This is an extension of the HTC EVO Shift 4G FAQ which can be found here.
[SIZE=+3]ROOTing, Flashing, and Custom recoveries[/SIZE]
[SIZE=+2]HTC EVO Shift 4G[/SIZE]​
[SIZE=+1]Q1: How do I root my phone....?[/SIZE]
There are several methods for rooting the EVO Shift 4G, below are some of the most used/reliable/common ones in no particular order:
[TOOL][ROOT] Shift ROOTility [1.13.13] by @CNexus
[VIDEO GUIDE] FULL S-OFF ROOT for Evo SHIFT. Froyo (2.2) + Gingerbread (2.3.3+2.3.4) by @VICODAN
Root and downgrade for Android 2.3.4 {Script included - ShiftySonofA script dl added) by @Indirect
2.3.4 Latest OTA[2.77.651.8] Downgrade!! by @JohnnyCakeXM
[SIZE=+1]Q2: What is a custom recovery....?[/SIZE]A custom recovery takes the place of HTC's stock recovery once you root your phone. There are three custom recoveries for the EVO Shift:
Official ClockworkMod Recovery (commonly referred to as CWM)
Team Win Recovery Project (commonly referred to as TWRP)
ClockworkMod-Enhanced (commonly referred to as CWM-E) by dread7us
When choosing which recovery to use, read the ROM/kernel op that you want to flash, most of the time they will tell you which recovery is sorted for their project. In most cases both recoveries work just fine, so ultimately the choice is up to you, but if you decide to go with a recovery that the developer did not recommend, you still not receive support within that developers thread! ​
[SIZE=+1]Q3: How do I change my recovery ....?[/SIZE]
There are several ways you can do this
Via fastboot.exe
Download the ".img" file for the recovery you want to flash.
Move the "filename".img to the directory where your fastboot.exe program is located.
Boot your phone into fastboot mode (see the General FAQ #5 for how to do this)
Type the following in a command prompt/terminal shell in the directory where your fastboot.exe and <fileName>.img recovery are located:
Code:
fastboot flash recovery <fileName>.img
Via FlashImageTool **RECOMMENDED**
Download the tool.
Download the recovery.img file for the recovery you want to use.
Connect your phone to your computer with USB debugging enabled.
Open the tool, select your file and then select "recovery" from the dropdown menu.
Click "Flash" and let the tool do it's thing.
Via Terminal/ADB Shell **BRICK IS POSSIBLE HERE, BE CAREFUL WHEN TYPING**
Download the recovery.img file.
Open a terminal on the phone/adb shell from computer.
Type the following to navigate to the download folder
Code:
cd /path/to/download/folder
Flash the recovery to the recovery partition
Code:
dd if=./<recoveryFileName>.img of=/dev/block/mmcblk0p21

Thanks so much, buddy. Awesome work, these recoveries (TWRP and CWM) of yours.
Now digging through your device tree, trying to get a grab on how to compile this stuff by myself.

Too bad ROMs for this are few and far behind; it would've been golden if someone's up to the task of porting CM10.1 or 11 for this. Thanks for the CWM though, that'll be much appreciated.

I found this guid in other forum. It also have a link for a TWRP recovery.
http://www.htcmania.com/showthread.php?t=969144
Direct Link for the TWRP recovery>
https://yadi.sk/d/SSDNtX5xeMeDB
Note - I did not tried it!
This tutorial is what I have done on my device, I hope can use them my help
Emui installed in your device 3.0 beta we need to install this ROM but does not work...
We will need to download the ROM b370 here I leave the linck: https://yadi.sk/d/gqWACWBleVQAG
And we will do the following for installation, after downloaded extractor must install the Huawei on our computer here the link: http://forum.xda-developers.com/show...php?t=2433454
Then with the Huawei exhaust unzip the following
-Boot.img
-Cust.img
-Recovery.img
-System.img
Now you will have to download the android adb and the SDK tools, adb link here: http://www12.zippyshare.com/v/67744317/file.html
And put the adb on the local disk c and in the folder adb, place the custom recovery.
And we will do the following, execute the cmd in windows
And write the following: chdir c:\adb
And execute the following
-fastboot flash cust cust.img
-fastboot flash recovery recovery.img
-fastboot flash boot boot.img
-fastboot flash system system.img
-fastboot reboot
And ready we already have the system installed with the b370 and the system will tell us that it is Huawei p7 mini not the g6-l11
Now we go to the root of this phone
For that the tutorials need recovery twrp here:
http://www.htcmania.com/showthread.php?t=967406
This is a compilation of the user pepe0000 and there was where remove information in 4pda so stay us more clear tutorial
Agradeciemientos to pepe0000 for bringing us this recovery
He clarified that to install this recovery is mandatory to have the unlocked bootloader, but I know here in this link to go back: http://www.htcmania.com/showthread.php?t=939960
This tutorial was made by D.ceres which I also thank you for this tutorial
1.*descargar and unzip the contents of the ADB at the root of the C: drive * http://www12.zippyshare.com/v/67744317/file.html
TWRP G6-L11 2.*Descargue *: https://yadi.sk/d/SSDNtX5xeMeDB
3.*Copy the downloaded content to the folder file root ADB *
4.*Conect the phone to the computer in Fastboot (bootloader). *(Vol-+ botón de encendido)
5.* Holding down the SHIFT key, right-click on the ADB folder and select the option "Open command window" *
6.* In the command prompt, type without quotes "fastboot flash recovery TWRP_G6-L11.img" or if you want to rename to write the name that been placed
Enter 7.*Pulse now and execute the following code "fastboot reboot"
If you want to return to the original recovery you have to download this file: https://yadi.sk/d/cAphF5smcwmUX
And perform the same procedure.
Again I thank Pepe0000 also for your tutorial because of remove the info there and I couldn't do it on my phone

Official OTA Update Links and OTA updating modified systems

Don't forget to thank me and Radii it means a lot to us!
Click to expand...
Click to collapse
Upon discovering the reason people being given an error trying to flash OTAs in my TWRP recovery image I decided I would come up with a work around while I work out a way to fix it.
The following solution is group work between me and Radii.
If you came here just for OTA links then click HERE
Click below spoiler if you haven't installed TWRP on your device and you want to OTA update and then install TWRP.
First you need to download the version you would like, in theory you could backdate although this hasn't been tested and it may misbehave. For example the latest version as of 16/10/2015, build number cm-12.1-YOG4PAS38J.
On the spread sheet you will need two files, the fastboot and the signed. In the fastboot ZIP there is a file called recovery.img. Copy this to your android SDK platform tools folder. Now with the signed ZIP you either copy that to the same folder (platform-tools). Put your phone into fastboot mode and type.
Code:
fastboot -i 0x2b4c boot recovery.img
Or the name of the recovery if you renamed it.
Your phone will boot into Cyanogen OS Recovery. From there click Apply Update (Top option) and click ADB Sideload. Then type,
Code:
adb sideload cm-12.1-YOG4PAS38J-ham-signed.zip
Or whatever you renamed it to.
Reboot and you're done! Now you'll need to install TWRP to flash things like SuperSU and Xposed.
To install TWRP you need to download the latest TWRP image from HERE move that to platform-tools and type (with your phone in fastboot mode/bootloader mode of course)
Code:
fastboot -i 0x2b4c flash recovery "recovery.img"
Changing the name in the quotations to the name of the recovery and removing the quotes.
Click below spoiler if you have installed TWRP on your device and you want to OTA update and restore/preserve TWRP
Do the same as above, I have discovered it's impossible to preserve because Cyanogen will auto-write it's own recovery to the recovery parition.
Nerdy stuff
If you're wondering why you can't OTA without going through all this then it's because Cyanogen OS will do checks to see if the System has been r/w mounted. If so then it will stop all OTAs from installing. Simple when you think about it.
FAQ
Q: Why isn't TWRP still installed after installing the OTA? A: Because Cyanogen OS will write over the recovery partition with Cyanogen Recovery
Q: Will I lose all my data? A: Don't wipe and no, you can dirty flash to preserve data.

Thanks for your work, really appreciated.
However, it sucks a bit that we have tons of work just for the OTA updates if we want root, i guess we should annoy Cyanogen to add a Superuser option to CyanogenOS...

It's designed to be shipped with devices like Samsung or LG's ROMs they'll never add that option.

Why not? root is a normal option in CyanogenMod, why wouldn´t the "commercial" edition not support it? I see no reason they can´t add it to PrivacyGuard.
Here one of the forum admins said hes telling the team to add it -> http://community.cyngn.com/t/reques...-thethering-and-inbuilt-superuser-access/97/2

Breadcrust,
did you try this method used for oneplus one phones with CyanogenOS?
https://forums.oneplus.net/threads/flashable-zip-cm12-enable-integrated-superuser.297089/
https://github.com/julian-klode/bacon-superuser/
From what i´ve read OTA updates are working with it and all we need to do is update the recovery after installing a new ota, the script on github creates the patched boot files automatically, we just have to change the config to use the ZUK files.
All theory tho...as i don´t have my phone yet.

@othe01
No COS device allows you to flash incremental OTA if your /system partition is modified. Your quoted package puts compatible su binary in /system & flashes boot-debuggable kernel so that root can be achieved from both app & ADB. It has nothing to do with OTA. Your only choice is to get the signed zip & flash it manually.
@Breadcrust
It would be nice to put incremental OTA zip links too. My posts regarding OTA links also contain them.
:highfive:

sounded different here: [FLASHABLE ZIP] [CM12] Enable integrated superuser
But is prolly just a misunderstanding from my side.
How exactly does CyanogenOS check if System is modified and can´t we patch the check with an xposed module?

@othe01
He must used the signed zip to update. Regarding OTA faliure, I've discussed the issue here: http://forums.yuplaygod.com/index.php?threads/15124/
You need to registered in the forum to read, so I've uploaded a PDF of the same: https://drive.google.com/file/d/0B9zZIJPXbMsubkFBYmZ4eGtMQjQ/view?usp=sharing
I personally own OnePlus One & YU Yureka so already have a good experience with these things.
The whole procedure is clearly explained - no 'Xposed' module can bypass it. You can, in theory, deploy a file based OTA (I've already requested it through YU developers) instead of block based OTA or patch the update-binary to return always true (unmodified) value while checking the state of partitions.
:good:

@Titokhan I will post them later

@Breadcrust
for clarification:
-isn't "cm-12.1-YOG4PAS38J-ham-signed-fastboot.zip" is the same as "cm-12.1-YOG4PAS38J-ham-signed.zip", but with the recovery image include, can sideload this file using the same process you mentioned?
-if the phone is rooted, boot with the COS recovery and sideload the "cm-12.1-YOG4PAS38J-ham-signed.zip" will not work as the system partition is already been modified by the root process, am I right?

re: above
if using cos recovery and sideload via abd or from file the full signed version , and your have root, it will work, root will be lost though.
fastboot zip has recovery signed doesn't. you need to flash recovery extracted from the fastboot zip and then flash the signed full zip using cos either using abd or sideload file onto system

I flash the rom, but when I insert CDMA SIM into slot one, there is no signal
and there is no option to choose band from the menu.
would you please instruct on how to get CMDA works?

@taitai
As you can see here, it is not an CDMA device.

As regards technical faults as well we're unable to help in most cases as ROMs are from Cyanogen and unedited.

I have a chinese version of Z1 and it has CDMA capability

None of them do. They're the exactly the same under the hood.

Special thanks to a lady called Alexandria and @clcombs262 for getting me access to a server to build roms/recoveries for these devices . Hey Thanks A Million You are the Stuff !!!
Twrp Builder for the fist port of twrp for tetra

Fastboot fix:
Fastboot fix:
So most users don't have fastboot access
We have a fix for this.
Ok the very first thing you're going to want to do is gain some type of temporary root shell so that we can downgrade the bootloader by writing directly to the partition so that we can then issue a command to reboot to bootloader and use fastboot to unlock your bootloader and we're going to want to do that without using sugar mtk so that we don't end up with our unlocked device from eBay being relocked like a brand-new Tetra from Walmart.
So we are going to be using a kernel exploit called mtk-su to gain the temp root access.
Here is the kit
https://drive.google.com/open?id=1JfLzT6F66yBj6Qor_t4P9340CwLz5Y18
Instructions For Windows Users:
Instructions from a booted Tetra that has no reboot to fastboot functionality:
Extract this zip.
open the folder location in a terminel/CMD/Powershell window...
enable developers options.> enable OEM unlocking.>enable USB debugging
make sure the drivers are installed for your phone on windows {likely they are }
first get device recognized by adb
./adb devices
accept the prompt on the device.
after this move on
copy paste these commands one by one into terminal...
Code:
./adb push exploit /data/local/tmp/exploit
Code:
./adb push U8M8Y0Y0CT00.mbn /data/local/tmp/lk.bin
Code:
./adb shell chmod +x /data/local/tmp/exploit
Code:
./data/local/tmp/exploit
NOTE: the file exploit is just Mtk-SU renamed to " exploit "
Wait for it to say new UID 0
should now see # instead of $ in the prompt...
then type this command
Code:
dd if=/data/local/tmp/lk.bin of=/dev/block/platform/bootdevice/by-name/lk
after that completes type this...
Code:
reboot bootloader
Now you should see the fastboot prompt...
ENJOY
Instructions For Linux Users:
instructions for linux are the same except,
remove the
Code:
./
from each adb command...

Unlocking the bootloader
Unlock bootloader:
WARNING THIS WILL ERASE ALL OF YOUR DATA
Well this is done the same as any other device with fastboot.
here's how for the neewbz out there.
Code:
fastboot oem unlock
then confirm by pressing the volume-up key on the device
and then type this code to reboot...
Code:
fastboot continue
Let your device fully boot up then go through the setup wizard again {I always skip through it} and re-enable developers options and adb debugging.
Your bootloader should now be unlocked and you will see a warning message each time it boots. this warning can safely be ignored, In fact it can also be removed completely but that's a subject for a different topic.
NOTE:
though your bootloader is unlocked there are 2 files inside the device that will replace your recovery with the stock one on boot if you don't remove them, but you also have to disable dm-varity in the fstab before you remove the files or you'll get a soft brick.
Fstab lives in /vendor/etc partition
the easiest way for most users to fix this is to follow the instructions in this gsi prep package by @PizzaG ,
https://drive.google.com/file/d/1ir_S_fEX3SU3G-Fk7-YFl2z5NXfsIJ5l/view
the thing to remember is that you only need the backup to restore from his package, and DO NOT DO the LK DOWNGRADE from his package it's old and uses sugar MTK to replace LK and it messes up network stuff in the process.
You already completed the LK downgrade if you followed my instructions in the last post.
You should be ready to flash the recovery of your choice, do a backup from that recovery and then follow PizzaG's instructions on how to replace your backup with his one.
then if you wanted cricket-rom restore it all if not just restore /vendor and /system to get gsi working and fstab fixes and to auto remove the files that are in stock system to replace recovery on booting

Flashing the custom recovery
Flashing recovery and choices of recovery:
You can use any recovery that yourself or anyone else ports to the Tetra.
The TWRP images in the pizzaG package work but adb is broken in those.
So if you want TWRP that has ADB functionality "sideload etc."
grab the version here:
https://forum.xda-developers.com/showpost.php?p=79815342&postcount=253
Other Better Alternatives:
Pitch Black Recovery Project Ported By LgPWN'd:
https://forum.xda-developers.com/android/development/unoficial-pitchblack-recovery-alcatel-t3946122
Red-Wolf recovery ported by LgPWN'd:
https://forum.xda-developers.com/android/development/red-wolfrecovery-alcatel-tetra-5041c-t3946121
So Choose your recovery, and flash it in fastboot...
Code:
fastboot flash recovery recovery-file-name
Example :
Code:
fastboot flash recovery TWRP.Tetra.img
after this to get to recovery without booting all the way back to system
Code:
fastboot oem reboot-recovery
You should now be in a custom recovery environment .
Remember if u want to use userdata partition u need to disable variety in fstab mentioned earlier, and u need to format data to f2fs to
Kill the encryption and then reboot to recovery to be able to use data partition.
Also there is a file that will cause the stock recovery to over write your custom one.
/system/bin/install-recovery.sh
Rename it or delete it from custom recovery before rebooting
Also some people have had errors using the menu to format data
From the p.b.r.p port.
If it happens to you, try it from one of the twrp images in pizzaG prep package
The older version works when the newer ones don't sometimes
Enjoy !

How to root the Tetra
Reserved
To root or not to root....?
How to root the Tetra.
To root the tetra, follow up instructions to unlock Bootloader flash recovery
then flash your choice of root.zip
When using LOS roms I prefer to use the addon-su from LiniageOS extras
{google search that ^^^} which works out of box just flash and reboot
or you can also use Magisk which is many peoples favorite.
But to get magisk to work you'll need a few things,
first the latest magisk zip to flash, secondly to get it to show you a root prompt in gsi's you'll need to add back some missing library files.
Luckily Myself and @PizzaG have made a flashable zip that can be flashed from custom recovery to do just that.
It'll be in the attachments to this post.
AND NO THIS MAGISK FIXER WILL NOT WORK FOR ANYTHING BUT A TETRA 5041C !!!
so to get magisk running:
first flash :
Magisk_17.2+(GSI_Android_9-Helper)[7-12-2019].zip
then reboot back to recovery,
then flash magisk latest zip
reboot and enjoy root

Gapps to flash or not to flash....?
This is solely up to personal preference.
some users like google and the convenience of google apps,
some users Absolutely abhor Google and all of it's policies and data collection.

A word about Carriers and networks
lock/unlock status:
Carriers or other third parties that have unlocked your tetra have done so by manipulating the data contained in your NVRAM and NVCONFIG and Simlock partitions....
so you can factory reset , flash boot.img or system.img or vendor.img and still retain your unlock, though you may need to adjust your APN settings depending on your choice of ROM.
How to keep from accidentally re-locking your network:
The only way this happens is when you flash those protected OEM partitions or corrupt the data in said partitions.
The sure-fire way to relock a tetra to At&t is to flash / upgrade it using SugarMTK tool
as it flashes EVERY partition with the latest stock released from the server in china or where-ever.
What you can do if it happens to you....
There's not a lot you can do about it. Your carrier will likely refuse to help, at least thats what other users have reported to me.
What you can do is contact any reputable Unlocking service and most times they can re-un-lock it for you.
BUT NOTE: you want to use someone that has the cable-unlocks via pc and usb cable, not the ones who offer some code as your device likely will never ask for the code if you changed things to get this far.
And
Why we can't discuss it further here...
WELP, the big deal here is liability and the Forum rules of XDA.
We are not to discus these things because they actively seek to bypass Carrier Network Restrictions
and as such it's against XDA rules.
However if you find yourself in this position, you might want to contact someone at our device support group for help/advice as we have had to fix this situation before.
we can at least point you in the right direction,
since here on XDA i'm not allowed to Promote/recommend anyone to help fix this because it'll cost you money PERIOD and that's basically considered advertising.

Bricked Devices
Bricked Devices.
Un-bricking.....
FIRST-OFF WHY HAVE YOU NOT MADE A COMPLETE BACKUP TO STORE SOMEWHERE OFF THE DEVICE TO HELP YOU IN THESE SITUATIONS?
that will be your saving grace in most soft-brick situations, where you can still get to recovery Via button combo or via
Code:
fastboot flash recovery recovery.img && fastboot oem reboot-recovery
To unbrick from a hard brick our only choice for now is SugarMTK.
you can find it in @PizzaG Gsi Prep package...
NOTE:
flashing with sugar restores ALL partitions of the device to factory stock release...
what this means is that even if your carrier or some service unlocked your device to use on networks other than At&t you will NOW be stuck with At&t or cricket or it's MVNO's
SUGAR MTK WILL LOCK THE NETWORK ON YOUR TETRA EVERY TIME

We are currently working on.

I there an updated easy way for root yet preferably without pc

Thanks for the guide and fastboot fix. I'm running the LineageOS gsi based on pie, but along the way I have lost the ability to turn on wifi and bluetooth. I'm new to mtk roms, so I was wondering where the firmware for the radios is living.

Nope, you can however use mtk-su with a terminal emulator to get tmp root then u could use DD to make a copy of your boot.img
then u can use magisk manager apk to patch said boot.img, and then u can write that back to the device using mtk-su and terminal emulator. but this still requires you to have the device bootloader unlocked i believe or you'll brick

I have tried to get to your website "http://a-team-solutions.dynu.net/" to no avail. I have tried from many different sources both with and without vpn. I have posted in the thread for the site but have not received a reply. Is the site still available? I would gladly pay for the registered version if it solves my bricked phone problem.
Thanks
