Increase storage 2.49Gb for Qmobile A700, Gionee Gpad G2, Walton Primo N1

Getting short of memory with 1Gb internal Memory only? even tried 2.73Gb mod available but then you still run out of space as you can not move apps to the SD card?
Every time you need to flash a new ROM you need to revert back to the original storage by flashing and restoring... lengthy process.. here i put up a solution for all of you guys using the device or any of its clone. i have Qmobile A700 and tested this on Walton Primo N1 as well...:angel:
Do it ONCE and keeps same storage FOREVER. no matter how many ROM's you change or Flash via custom recovery.
Point to Note here is if you flash this method your current ROM will remain installed, only changes that will incur are Logo shall be replaced, partitions shall be modified and recovery will b replaced with twrp. If you need to keep current logo and recovery then replace the logo.bin and recovery.img with the ones you need to keep in the folder files_to_flashtool you can go to any ROM you want after this. Even when you are flashing a new ROM you don't need any zip to change storage, like it used to be with 2.73Gb Mod. just flash the ROM and you will have 2.49Gb Internal Storage in any rom. But Please take Backup of your Phone just in case anything goes wrong. i shall not be responsible for anything bad happening to your phone if you don't follow the method PROPERLY.
Method and Instructions.
1. Download the files from the Link given at the end.
2. Unzip the folder Tools.zip.
3. Unzip the Drivers Folder.
4. Install Drivers on your PC install ADB and fastboot drivers and device drivers as well.

video tutorial how to flash and the Work Around for if you get stuck on boot logo
Here is the video tutorial how to do it
http://nibs.tinytake.com/sf/OTcwMDFfNjUxODgy
Please note you may require a work around to get it working if you are on stock ROM. so please please keep backup of your ROM before following this method. i shall not be responsible for any loss of Data or damage to your device. …
After the process was finished i rebooted my phone on the stock ROM, it did not boot. so i figured out a workaround for stock ROM users, after the flash is complete when you are on stock ROM (or even any other custom ROM) and phone does not go beyond boot logo, reboot to recovery and restore your TWRP backup.... after the process is complete reboot and enjoy 2.49Gb internal storage or you can also flash this and then install any custom ROM over it. and still you will have 2.49 mod. and it will remain the same untill you restore stock ROM using SP Flash Tools.
Thanks and Enjoy :good::laugh:
Dont forget to hit thanks if i helped you.

[Guide & Download Links] UHANS A101S TWRP & Custom ROM

Hello,
I have successfully installed TWRP and a custom ROM on a UHANS A101S. And now I want to share the files and instructions, because they come from Russian forum 4pda.ru (thanks and credits to them).
Warning: I do not take any responsibility for whatever outcome you have when trying this on your device. It worked for me, but everything you do is your own risk.
Now, here's how it worked for me:
(Instructions are for UHANS A101S only, NOT for A101)
Installation of TWRP:
1. Download TWRP recovery image for UHANS A101S. Check that you get the correct recovery.img for your firmware build. Also download the scatter file for the UHANS A101S.
2. Download SP Flash Tool and driver for UHANS A101S.
3. Install driver on your PC and reboot your PC.
4. Unpack SP Flash Tool. Unpack scatter file. Put scatter file in same folder as recovery.img file.
5. On your phone, enable USB debugging mode in developer settings. (To activate developer settings menu, tap 7 times on your build number in Settings > About).
6. Switch off phone. Remove battery. Wait for 10 seconds. Put battery back into your phone, but don't start it! Keep it switched off.
7. Start SP Flash Tool with Admin permission. Click "scatter-loading" and navigate to the folder where you unpacked the scatter file and select it. Make sure that "Download Only" is selected in drop-down menu on the left. Then click the "Download" button in SP Flash Tool.
8. Connect your phone to the USB port of your PC and press Volume Up on your phone, so SP Flash Tool will recognize it.
9. If everything goes fine, in SP Flash Tool a red progress bar at the bottom turns yellow, then green and finally you get a pop-up with a green check mark.
10. Now you can boot into TWRP. To do so, unplug phone from PC and press Power On and Volume Up simultaneously.
Download links for installing custom recovery TWRP for UHANS A101S:
Download from Mediafire
(For the recovery.img file, choose DRV.TEST version if you see this appendix in your firmware version. Otherwise, option v3.05 is correct).
If you want to restore stock recovery, recovery image from firmware version 3.05 is available too.
To install custom ROM, download your preferred ROM, copy it to your phone and flash from within TWRP.
Custom ROMs for UHANS A101S:
CLEAN MOD (Stock ROM without bloat)
MOKEE ROM (Gapps: no, root: no)
Resurrection Remix 5.7.4 (Gapps: no, root: yes)
To get Google Play store, flash Gapps package.
Download Gapps package here (choose ARM and Android 6.0):
http://opengapps.org
(Pico or Nano package recommended).
If you want root access and if it's not included in the ROM, you can flash SuperSU Zip using TWRP:
SR2-SuperSU-v2.79-SR2-20170103215521.zip
Stock ROM from UHANS (via SP Flash Tool):

Source: http://www.uhans.cc/Service/index

A new custom rom
Hey guy! Thanks for your ROMs, I have Uhans A101S and they worked properly but I wanted to try something else with a google stock experience and so I wanna ask you if you can create another custom ROM (like lineage os) for this device.
Thanks a lot!

[GUIDE][20-MAY-2019]HOW TO FLASH Z010D ROMs on Z010DD (8.1 and 9.0 ROMs).

This guide is specifically aimed for Z010DD users who want to flash custom ROMs:​If you want to stay on stock and only wanna flash TWRP and root the Stock ROM, please skip this thread and refer to @jide1 's guide here instead: https://forum.xda-developers.com/as...ot-asus-zenfone-max-zc550kl-qualcomm-t3652518​
Things to be noted beforehand:
1. Make sure you are on the latest/final stock rom/firmware
2. Need Unlocked bootloader (Linked below, install the apk and follow the steps)
3. Take backup of all of your data from the internal storage. (To avoid depression if accidentally wiped your precious data)
4. Minimal ADB and Fastboot (Thread Linked below, Download from there and follow on-screen steps).
Steps:
A. To flash TWRP:
1. Once you have unlocked the bootloader, download 'minimal adb and fastboot zip' and PBRP zip(extract img from it).
2. Boot into fastboot by switching off the device, then POWER + VOLUME 'UP'. (You'll enter CSC ode screen, which is fastboot so don't worry)
3. Place the recovery image into the fastboot folder and open a command window there.
4. Connect your device, then type 'fastboot devices' and Enter, just to verify if your device is shown.
5. type: fastboot flash recovery recoveryname.img
THE NEXT STEP IS IMPORTANT, Pay Attention.
6. Now REBOOT Directly to twrp by holding POWER + VOLUME 'DOWN'. Don't boot into system else stock recovery will get restored.
B. Preparing for Flashing ROMs:
Once you have booted to twrp successfully, you will need to 'format' all the partitions, which includes:
System, Data, Cache, Dalvik/ART Cache, & Internal Storage.
HERE YOU WILL LOSE ALL OF YOUR DATA, YOU HAVE BEEN WARNED ALREADY SO, yeah.

Bugs and Notes:
1. Notification LED doesn't BLINK when a notification arrives, it stays on (colors are correct though).
2. VoLTE is broken on pie roms (ignore the volte logo), stick to Oreo if you want VoLTE. (LTE data works fine).
3. Reboot Sometimes get stuck in black screen, its RANDOM, LONG Press the power button for 15 secs instead if that happens.
4. If any ROM contains 'Always On' functionality, disable it as the feature doesn't work properly. (Ambient display has no issues)

[Guide][Installation][Fix]Switching from stock ROM to custom ROMs + Installing stock ROM after a brick or other Failures ( Mi A2 Lite - Daisy)

This guide is general guide for the installation of custom ROMs. I will also include guide to install stock ROM on devices which have been bricked or for solving various problem which you may encounter in custom ROMs. There are other guides for the same purpose but most of them are outdated and many of you seem to ignore old guide despite the fact that those guides can be helpful.
This is guide is only relevant for installation of custom ROMs which were released up to the date of posting this guide or up to android version 11. Recovering a bricked device can be done in the same way as to this one but installation instruction for devices with android version greater than 11 may differ.
DISCLAMER
Code:
I am NOT responsible for bricked devices,
thermonuclear war or for you getting fired because your alarm app failed.
Make sure the bootloader is unlocked and never lock the bootloader

EDL FLASHING (For windows only)​
EDL flashing can be helpful when flashing every partition of device is needed either for clean stock base or after brick or after some failure.
EDL flashing can be the final resort when everything else fails.
PREREQUISITES
1) A good USB cable, your phone
2) A PC with either windows or linux
3) Fastboot drivers from google and edl drivers from qualcomm
4) Platform tools from google
5)Fastboot rom. This should be full rom in .tgz format.
6)Xiaomi flash tool (LATEST VERSION AVAILABLE)
Install the adb and fastboot drivers from google. If you are on windows 10 or greater then you can also use "windows update > optional updates" to update adb and fastboot drivers + edl drivers. For the installation of drivers always use trusted sources and don't turn of driver signature enforcement if you can.
Extract the platform tools in a convenient folder, we will be doing our operations from this folder for fastboot and adb opeartions. Extract the fastboot ROM and place that in convenient folder as well. And for xiaomi flash tool extract the zip and launch XiaoMiFlash.exe .
If you can access fastboot in you phone then the phone can be booted into edl mode through fastboot else you have to take out back cover and short the testpoint pins to make the device boot into edl mode (see the attached image ).
If you can access fastboot. Boot into fastboot and type the following command in terminal.
To check if device is connected properly and drivers are properly installed
If no devices is shown then connect device properly with good usb cable and check the drivers.
Code:
fastboot devices
To boot phone into edl mode. This is only possible if the bootloader is unlocked else testpoint-edl is the only option
Code:
fastboot oem edl
The device should be shown as COM device in device manager ( Windows ). If not then either drivers aren't installed properly or your phone isn't in edl mode.
Now click on refresh button in xiaomi flash tool. Your device should be recognized as com device. Set the path to the images folder ( extracted fastboot rom ). Select CLEAN ALL option . If everything is good then click
on FLASH. The flashing process should start now. After the process completes keep pressing power button to boot device into the currently installed ROM.
Just install the rom and setup once even if you're going to flash custom rom next. This reduces various problems which may come in custom ROMs.
If any error occurs then try the following:
Make sure you are using latest flash tool.
Good fastboot rom (shouldn't be corrupted )
Good USB cable and try different ports of the PC.
The flashing should be done immediately after booting to edl. If not then take out battery and reconnect it if you have back cover open(In case of hard brick). Or keep pressing power button and volume down to boot into fastboot and boot to edl mode again from the above instructions(If fastboot is accessible)
For booting to edl using testpoint:
> Take out backcover
> Disconnect battery
> Short the pins
> Flash
> Connect battery after flashing is complete
> Keep pressing power button to boot into system.

qdl flashing ( linux only )​
For very detailed guide github -> bkerler edl
Thanks to DEFXZ and LinkBoi for suggesting this alternative.
Make sure you have platform tools, fastboot rom and other prerequisites to detect device properly.
clone the repository in convenient place
Code:
git clone https://git.linaro.org/landing-teams/working/qualcomm/qdl.git --depth=1
change to qdl directory
Code:
cd qdl
Build qdl tool
Code:
make
Finally flash the rom
Code:
./qdl --storage emmc --include /path/to/stock/images /path/to/stock/images/prog_emmc_firehose_8953_ddr.mbn /path/to/stock/images/rawprogram0.xml /path/to/stock/images/patch0.xml
The paths are the paths to various files inside the images folder which will be obtained after fastboot rom is extracted.
For further informations:
Original github link
qdl discussion in XDA

FASTBOOT FLASHING​
PREREQUISITES
FASTBOOT DRIVERS
PLATFORM TOOLS
FASTBOOT ROM
GOOD USB CABLE
PC WITH WORKING USB PORT
See this for meeting prerequisites.
Install fastboot drivers, connect device to PC via USB.
Extract platform tools into a convenient folder.
Extract fastboot ROM into a convenient folder.
Go to platform tools folder ( this will contain files and executable like fastboot.exe) and open powershell or any terminal window there
[ shift + right click and select open (powershell) window here ]
Type this command to see everything worked correctly.
Code:
fastboot devices
If not then check every step properly.
Now execute the script to flash the ROM.
Execute flash_all.bat script for windows PC.
Execute flash_all.sh script for linux PC.
If platform tools cannot be accessed system wide then.
Code:
./fastboot devices
will provide fastboot devices information.
For flashing drag and drop flash_all.bat or flash_all.sh file into the terminal.
Code:
'/media/user001/user/daisy/stock_roms/daisy_global_images_V10.0.18.0.PDLMIXM_9.0/flash_all.sh'
It will look something like this in linux and similar in windows.
If any error occurs the search for particular error. Most of the times the error is due to corrupted fastboot ROM or bad connection between phone and PC.

FINALLY! FLASHING CUSTOM ROM​
STEP 0
Flash(if not flashed already) the stock base recommended by particular ROM, if the ROM doesn't recommend a specific stock base flash 10.0.18.0 from the above instructions.
PREREQUISITES
TWRP or ORANGE FOX RECOVERY
Fastboot drivers and platform tools (details above )
The ROM which you want to flash, choose from here
GAPPS package if rom is vanilla and you want to install it.
Magisk if you want to root.
As you may have known by experience, our device doesn't have recovery partition so, flashing recovery through fastboot isn't possible. For flashing recovery first we need to boot recovery image and then only we can flash it.
If you want to use twrp:
Download both twrp*.zip and twrp*.img and place it in a convenient place.
If you want to use orange fox recovery:
Download orangeFox*.zip and extract it.
Keep both the .zip and .img file in convenient place.
If you have sdcard then copy ROM file, gapps, magisk, twrp or orange fox files into sdcard.
If not then there will be further instructions.
Now, connect the phone to the PC via USB and enable usb debugging. And open terminal in the platform tools folder as in above instructions.
Check device connectivity:
Code:
adb devices
Reboot into fastboot:
Code:
adb reboot bootloader
Check device connectivity:
Code:
fastboot devices
Lets check if the bootloader is unlocked:
Code:
fastboot oem device-info
If bootloader isn't unlocked you won't be able to flash custom recovery into the device. So, first unlock the bootloader. This should be allowed in the developers option of your phone first. This will factory reset the device.
Code:
fastboot oem unlock
Now if everything is good then it's time to boot into custom recovery:
Code:
fastboot boot recovery.img
recover.img is name of image of whichever custom recovery you want to use.
Code:
fastboot boot '/media/user001/storage (1)/daisy/twrp/twrp-3.5.2_9-2-daisy-unofficial.img'
It's like this in my case. You can drag and drop after typing fastboot boot
The phone should now boot into custom recovery. If it ask for decryption then your lockscreen password should work there.
if you want to flash recovery only then find the recovery.zip you want and flash it.
The steps further is also valid for moving between different custom roms. The term used for such process is CLEAN FLASH.
For Flashing custom ROMS :
SOMETIMES FLASHING INSTRUCTIONS MAY DIFFER SO, BE SURE TO CROSS CHECK FOR INSTRUCTION IN ROM SPECIFIC XDA THREAD OR TELEGRAM GROUP
The following action will wipe userdata if not wiped already. Be sure to backup data before these steps. Also if you encounter any future problems full backup from custom recovery may be able to solve most of the problems. So, be sure to keep full backup(including every partition) of your device.
Go to main menu > wipe > select all except internal storage and microSD.
Swipe right to perform wipe.
Install custom recovery by flashing recovery.zip
(This is done in case adb push doesn't work below and sdcard isn't available for flashing)
Again go to main menu > wipe > format data
Type yes and press enter.
If you don't have files in your sdcard then:
push rom file + gapps + other files into your device through adb push.
The command will be something like this:
Code:
adb push '/media/user001/storage (1)/daisy/posp/potato_daisy-11-20210919-dumaloo.v4.2.3+20.Community.zip' /sdcard
If adb push fails to work then you can reboot recovery and simply copy the files through file explorer.
Reboot to recovery only if you had installed recovery after wiping system else the device will soft brick
Now flash the rom.zip by selecting the file and swiping right.
Flash custom recovery if the ROM doesn't contain recovery
We have to change current slot even if we don't want to flash anymore things.
Latest recoveries changes slot automatically So, go to main menu > reboot > recovery
Now flash files which you want to flash i.e. gapps and magisk.
Again, Don't flash gapps if the ROM is of Gapps variant
Most of the roms now have implemented FBE (File Based Encryption ). So, you need to format data before rebooting to system. Again, check for specific ROM installation instruction if that is required or not. If you keep data from previous ROM that won't be considered a clean flash so, for proper clean flash format data before rebooting to system.
reboot system

MOVING BETWEEN DIFFERENT VERSION OF SAME CUSTOM ROM
Dirty flash or OTA ​
Most of the newer ROMs have seamless update ( even the unofficial ones ). The OTA update is simple. Just go to updater ( in settings > system or native app, depends upon the rom). If your ROM is of vanilla version then make sure gapps and/or magisk which you have installed, your ROM and custom recovery all support addon.d survival script. If they don't then you may have to flash everything again after update process is complete.
If custom recovery itself doesn't support update then you may need to choose different recovery or dirty flash ROM from the recovery. Don't worry most of the roms and both the recoveries for daisy support OTA and addon.d survival.
DIRTY FLASH​The process of flashing a ROM on top of existing one keeping the /data partition intact is known as dirty flashing. Such flashing must be done only on different builds of same ROM and it isn't recommended to flash build of lower version on top of higher version.
The steps for dirty flashing:
Download the update package.
Reboot to recovery
Enter password for decryption if encrypted.
Flash the update.zip package.
Reboot recovery, if recovery/rom doesn't support survival of recovery then flash recovery before rebooting to recovery.
If gapps and/or magisk survival isn't supported then flash gapps and magisk, make sure gapps is of the same type which was flashed before.
reboot system

Hi @user-001 thanks for this.
I'm on a stock A2 lite thats never had anything done to it , am i right in thinking i follow the clean flash section ?
You mention in there
We have to change current slot even if we don't want to flash anymore things.

I'm not fully sure what that involves could you break it down the steps a little for me.
I've downloaded all the files and am set up but i'm unsure on the Flashing fastbbot section where you say to use these files..
Execute flash_all.bat script for windows PC.

Is this a section i can bypass ? if not where can i get them from ?

1) Yes you should follow clean flash instructions.
2)Changing of slot is done in custom recovery. Precisely in the reboot menu. But newer recoveries automatically switch the slot after flashing the rom , just be sure to reboot to recovery after flashing the recovery zip file.
3) the flash_all.bat script will be inside the extracted rom(fastboot rom) folder. You can use xiaomiflash too for flashing through fastboot.

Hi thanks for the reply,
I'm getting confused with all the various guides all seem to want you to do it a different way.
As i'm wanting Lineage thier instructions are...
Installation:
Download the latest build from here
Download LinkBoi00's version of TWRP here
Reboot to bootloader (adb reboot bootloader)
Fastboot into TWRP recovery (fastboot boot twrp*.img)
Do a factory reset in TWRP
Flash the latest build of Lineage OS
Boot into your new phone

Theres no mention of the edl or fastboot flashing and also the fastbot rom i downloaded doesnt have the flash_all.bat script in the zip file.
So do i follow thier instructions or these ones ?
Cheers

This guide deals with how to do something rather than what to do, meaning you should always do what particular rom suggests but the way to do this is mentioned here.
edl or fastboot flashing comes under clean flashing with new base, most of the time you aren't required to do this.
The script should be clean_all.bat or something similar just don't execute script with lock in the name(it will lock the bootloader)
And if you're already on the recommended base you don't have to flash the fastboot rom.

First of all, thank you very much for the detailed guide. What you have done here took a lot of work to do but it will help a lot of people (including me) to understand, albeit rudimentarily, the structures and functions of the devices etc.
For all that, thanks again.
When I start using the guide, I will update this post with any questions, such as :
fastboot boot '/media/user001/storage (1)/daisy/twrp/twrp-3.5.2_9-2-daisy-unofficial.img'
why not doing below? (For those who, like me, are not very familiar with linux.)
1. > adb push <twrp.img> /sdcard or same adb push "C:\platform-tools\twrp-3.5.2_9-2-daisy-unofficial.img" /sdcard
( which means push <file> from "adb|platform-tools\ folder" (eg. C:\platform-tools\)
into the root of <internal storage> | /storage/emulated/0 )
2. Reboot from adb to fastboot:
> adb reboot bootloader
3. Boot the image from <internal storage>:
> fastboot boot /sdcard/twrp-3.5.2_9-2-daisy-unofficial.img
What is the "Red" pointed and "Yellow" addresses"?
fastboot boot '/media/user001/storage (1)/daisy/twrp/twrp-3.5.2_9-2-daisy-unofficial.img'

I followed your "EDL FLASHING" post (#2) and it worked exactly as you mention!
In short, I was comming from unsuccessful flashing... but this is out of topic.
For me, did not worked the first time (after restarts) but the other day worked perfect.
The point is, most of times, it's becase windowz drivers.
We have to point that windowz needs their time to take the drivers in place. So, be patient and leave windowz to (not forced) restart(s).

That must be your terminal representing different type of character in different colors.
Or, Are you talking about something else ?

For future references, the extracted fastboot ROM should be like this and you need to execute flash_all.bat or flash_all.sh script depending upon your OS or terminal.

Of course I'm talking about something else. lol
I was talking about that 'strange' address. fastboot boot '/media/user001/storage (1)/daisy/twrp/twrp-3.5.2_9-2-daisy-unofficial.img' (explained in post #11)
There is not such a directories in my miA2Lite phone. Obviously, it's because you are on Linux or Mac (UNIX). On Windowz 'command prompt' syntax it's slightly different.
Thus, I typed fastboot boot "/sdcard/twrp-3.5.2_9-2-daisy-unofficial.img"
* /sdcard is the root of <internal storage> directory.
** On Windows, double quote the address, if it's include spaces.

The twrp image was on my pc(linux) i was booting directly from pc's terminal. And if you use only adb(or fastboot) then the paths are pc's absolute paths.
