- In the window cd .. and press Enter while typing up her only the drive letter (C: \>) see.
- Now you give a cd fastboot and Enter . In order for her in the folder.
- Now that off with Mate Vol - to the PC.
- Now you give fastboot flash boot boot.img and Enter, then fastboot flash recovery recovery.img and Enter.
This means that both you have flashed.
- Now disconnect the device on and off with soft Vol + Power.
- Then you can proceed with the instructions.
For users whose system is running:
- Download and unzip this file. The Update.app contained therein in the dload folder to the SD.
- This flash now.
- Now the Update.app the B137SP03 in dload folder and flash
- After that the device starts again with 4.4.2.

Thanks Foox1, Its working perfect, even i had this error at 95% on the first UPDATE.APP, and i did not have the 300 roll back version when rebotting, i succeded installing 137SP03 after that at the end i installed B141 and everything was perfect.
I think B141 is the best update by now... i got very good performance and battery life... try it.

I can't understand the second part.
First we flash the update.app we take from the folder "Mate 7 (Jazz-L09) V100R001C900B308-Transition_Pack"
Then we flash the second update.app with the B137 firmware?

Yes, the first matches of the bootloader and the recovery, the second flashes the entire system.

If my system running, you mean I'm running the lollipop, right?

Yes, if 5.1 is running and want to back 4.4.2. The first part is for users who have made it wrong, and the system will not boot.

I do the second part but nothing is happend. First I install the first file "update.app" then my phone reboot and then I install the second file update.app from B137, my phone reboot again but nothing it happens.

Question Lenovo Phab PB1 770m no operating system help

Hi all i have new Lenovo PB1 770m I attempted to root it the TWRP was installed but it was not rooted
then I tried to update the firmware to the latest 151111 and no go, in the end i managed to delete the operating system so now I can boot to recovery mode only, When I try to restart it comes up with No OS Installed, I have tried to install xposed v79 sdk21 arm64zip no go, Ok now I know that I am an IDIOT for
not making a backup of original system and not cheking the firmware was the same as the root guide,
On the top of recovery screen is :- 2.8.7.7 SevenMaxs and TeamWin Recovery Project, I guess this could
be an expensive lesson, I have been looking for an original ROM with no luck so any help would be very
much appreciated, Thanks pluto1956, Mike
ps used info and files from here to try and root. http://forum.xda-developers.com/andr...oting-t3290347

Well i did it. Is really simple but it seems nobody has this problem before. You need
- Download Stock Firmware from russian lenovo site
- The Tool i used is QPST_2.7.422 QFIL it cames with the Drivers (i used Win8.1)
- Put phone in Download mode (press vol up and down same time and connect phone to PC)
- Open QFIL program and select flat build
- In select programmer you select prog_emmc_firehose_8936.mbm
- In load xml i selected rawprogram_unsparse and path0
- After that you click download and wait like 4 min and when say finish succesfully you start phone manually
I hope this helps.

Thanks brother, yesterday i downloaded one russian rom in zip format and there was a .bat file included in it. i only double clicked and it flashed through adb and fastboot and it was successfull. i got the operating system 5.0.2 but WLAN is not working, tried flashing several time but no luck. i learned that it is still under warranty ..so sent it to warranty. in a week it will be back with be for testing again hopefully.
well i will try your method as soon as i get my beast again. Thank you so much for helping out in timely manner, really appreciate it brother.

it is very easy my friend just look into the only topic/thread about Phab plus in xda. it will guide you well.
if you get any error in recovery like footer is wrong/signature verification failed. connect your phone and first check if your device in being tracked by adb. use adb devices.
if your device appear in the list of devices ..use fastboot oem unlock then flash sevenmax twrp again after entering into temporary twrp as per phab plus thread.

Could you please elucidate more? I downloaded the ROM and the flash program. However, I've no clue how to get going. I don't even see the xml files anywhere (as mentioned by you).
Just don't want to screw it up bad so being little more cautious.

Hi, same here. I tried using QFIL and getting Sahara Fail. Then tried clicking on the bat file but its not working since the phone is not recognized. Please help.
EDIT : I got the QFIL working just now and my phone is working. Flashed the stock rom and I think it will be just fine.

My phone was wiped by me . I have TWRP and my phone is read as ADB interface (when in recovery mode). I tried adb devices and it returned 1f82f24b recovery. I also can access my phone memory from PC when in TWRP recovery which enables me to transfer files.
My problem is it is only read as ADB interface not as Qualcom COM port device. When I try Download_with_partition.cmd I get the error that it can not distinguish devices and to try. Any solution by those managed to install it successfully?

For everyone landing in this page due to wiping his OS of Lenovo Phab Plus by mistake (like I did), please refer to this thread:
Lenovo Phab Plus PB1-770M Stock ROM needed

[GUIDE] How to fix broken Sensors for both Stock and Custom ROM.

Guide to fix broken Sensors for both stock and Custom ROMs​
Note : If u are reading this then u have already lost your original WiFi Mac Address and also now your sensors too by flashing certain specific ROM builds . As per what I have seen is, only this type of users are affected with sensors too.
When u complete the procedure, u will be loosing your WiFi again ! So please take backup of your WiFi and Bt Mac address before doing anything ( if u have original one )
Procedure
1. Download fastboot stock Oreo ROM zip
2. Go inside the stock ROM folder
3. Go inside images folder
4. Check for persist.img ( this file is necessary )
5. Now check for rawprogram0 file
6. Open it in notepad ++
7. Inside it, u need to find a line like this
<program SECTORSIZEINBYTES="512" filesectoroffset="0" filename="" label="persist" numpartitionsectors="65536" physicalpartitionnumber="0" sizeinKB="32768.0" sparse="true" startbytehex="0x1a8000000" startsector="13893632"/>
8. Now u need to edit this line to
<program SECTORSIZEINBYTES="512" filesectoroffset="0" filename="persist.img" label="persist" numpartitionsectors="65536" physicalpartitionnumber="0" sizeinKB="32768.0" sparse="true" startbytehex="0x1a8000000" startsector="13893632"/>
9. Save and open Miflash tool
10. Copy ur Bt Mac & WiFi Mac if original
11. Go into bootloader / fastboot mode
12. Unlock bootloader if not done already ( fastboot oem unlock )
13. Now go into edl mode ( fastboot oem edl )
14. Your phone screen should now go black and LED light should be blinking ( if not try until u get this )
15. now keep your phone connected and open device manager app in your PC
16. You need Qualcomm QDLoader USB Driver to be installed in your PC for edl mode to work ! get it via following link
https://www.xiaomigeek.com/download-qualcomm-qdloader-usb-driver.html
17. after installing , open MiFlash tool , press refresh
18. This time u will see something like ( COM 8 ) or similar instead of device serial number.
19. Select clean and lock and press flash
20. Let it complete ! This time it won't reboot automatically to system after flashing is completed.
21. When it completes ( it will say Success ) . Reboot to system by long pressing power key
22. Complete the startup procedure and check Sensors !
23. Sensors will be fixed but WiFi will be broken
24. Now flash this zip via TWRP
https://www.androidfilehost.com/?w=files&flid=270334
25. Reboot ,your WiFi too now will be fixed
26. Now u can fix your WiFi Mac and Bt Mac to original state via their specific method !
Profit !!

Here is the solution for BOOTLOOP after 9.0 beta

Hello everyone ,
so , I've been this and here is what i did to get back to normal :​
1- download MiFlash and the oreo 8.1 (V9.6.8.0.ODHMIFE) fastboot image from here
2- download *adb* file that i upload , and extract the files
3- download this file ,and extract the files , you will find *TWRP* folder
4- copy or move *adb* folder to the C:\
5- use Miflash to flash the fastboot image
6- when your phone start bootlooping go to the fastboot in the phone
7 - open the *adb* folder and run *Command Prompt* , write *fastboot boot recovery.img*
8- when the TWRP start go to pc and copy *TWRP* folder and place it in the main internal
9-go to restore in TWRP and chose the backup folder , restore *Boot* and *EFS* and swipe (if it doesn't show anything to restore go to TWRP>backup and copy *2018-12-06--15-41-27_PQ1A181205006* folder into *TWRP* folder "not to backup folder")
10- now in TWRP go to reboot and click bootloader
11- you will go to fastboot , flash oreo 8.1 (V9.6.8.0.ODHMIFE) by MIflash
12- everything will get back to normal !! :highfive:
update (3-10-2019) :
i recommend to flash latest official mi a1 rom maybe well fix it (using fastboot) ,
any way here is new link for TWRP file http://www.mediafire.com/file/j6682qbs7qa5sg5/TWRP.7z/file
thanks to :
@joeyhuab for the advice
@berlin51 for the link
@abhishek987 for the recovery image file​

So this will not mess up any IMEIs or anything? Is this a universal solution for everyone who messed up?\
EDIT: Nevermind, used the guide, works fine. Thanks for that!

It's working. Thank you!
Just need to copy "2018-12-06--15-41-27_PQ1A181205006" to TWRP folder.

Can you explain a bit
Sent from my OnePlus5T using XDA Labs

If anyone is planning to flash Pie stable/beta
1. First take a backup of EFS from TWRP and Low level backup of all partitions ( system n data not needed ) with low level backup tool via EDL
2. In order to get Pie booted, you just need "System.img" extracted from the OTA ( use payload dumper) or just take the system.img file floating around here
3. Transfer System.img to adb folder >> Boot to fastboot and flash the system.img only
fastboot flash system_a system.img
fastboot flash system_b system.img
Everything works except dual 4G/VoLTE
Downgrade will also won't have any issues
> For Dual 4G/VoLTE, you also need to flash modem and rpm
fastboot flash modem_a modem.img
fastboot flash modem_b modem.img
fastboot flash rpm rpm.img
fastboot flash rpmbak rpm.img [ Optional]
But now if you try to downgrade , you might end up with bootloop
>> To Fix bootloop, boot to EDL
Flash the fastboot rom you were running before when you took back of partitions
Then Use lowlevel backup tool to restore all the partitions and reboot

Procedure is same as flashing fastboot rom via EDL mode with MiFlash but instead of flashing it from fastboot try it from EDL mode
Use this command within fastboot mode to get to EDL
fastboot oem edl
Total process will take 10+ minutes, once the flashing status changes to "Success", hold the power button for around 10 seconds to reboot

Check if those IMEI numbers are your phone ones only? AFAIK EFS is device specific which contains information like IMEI, MAC Address..

Is that for people who flash it through fastboot or is this required if we update to the stable through OTA as well?

There is no official fastboot rom yet, the one available has the contents of extracted payload.bin from the OTA
Even if you update your phone via official stable OTA, you will be facing same downgrade issues
Yeah i meant it for those who are planning to flash via fastboot as most OTA users with locked bootloader wouldn't bother to downgrade

Please help me I did the steps and manages to restore the stock rom, but I get a message saying "phone not allowed" And when I want to make a call tells me "mobile network not available "

If the IMEI is different then u haven't edited the QCN correctly
Flash Nougat firmware again via EDL
and this time edit the IMEI hex values correctly in the qcn file via hex editor
Also make sure u have converted your IMEI to hex values

[GUIDE][04oct][10or.E][Bootloader Unlocking]And Installing [Custom Recovery]

Before you start reading note that no spoon-feeding is done here and its a bit tricky if you are flashing Stock ROMs for the first time.
REQUIREMENTS:
-PC/laptop
-ADB-Fastboot Drivers / Qualcomm Drivers must be installed
-QFST tool / QFIL tool anyone required (QSFT RECOMMENDED)
-notepad ++
-Platform Tools
-Stock Nougat v82/v99 Firmware File
-AIO Tool for 10or.E Download AIo Tool Kit
-And A working Brain
Process:
First, install all the drivers and Flashing Tool then Extract the V82/V99 rom.
Then go where you have extracted the rom then go to the firmware folder there find (rawprogram_unsparse/rawprogram0) anyone and open that file with notepad ++ NOW HERE COMES THE DIFFICULT PART you need to delete some lines from that file so that it doesn't create any NULL IMEI issue when flashing the rom.
**NOTE YOU NEED TO CHANGE THE (rawprogram_unsparse/rawprogram0) FILE. BELOW LINES MUST BE CHANGE FROM BOTH FIRMWARE V82 as well as from V99 firmware. or else it will give null IMEI error.
After opening the file in notpad ++ find this lines:
filename="st1" label="modemst1" num_partition_sectors="3072" physical_partition_number="0" size_in_KB="1536.0" sparse="false" start_byte_hex="0xd682400" start_sector="439314" />
filename="st2" label="modemst2" num_partition_sectors="3072" physical_partition_number="0" size_in_KB="1536.0" sparse="false" start_byte_hex="0xd802400" start_sector="442386" />
[FROM THIS TWO LINE YOU NEED TO REMOVE THE "st1" and "st2" ] THEN
filename="fs_image.tar.gz.mbn.img" label="fsg" num_partition_sectors="3072" physical_partition_number="0" size_in_KB="1536.0" sparse="false" start_byte_hex="0x10008000" start_sector="524352" />
[FROM HERE YOU NEED TO REMOVE "fs_image.tar.gz.mbn.img" ] THEN
filename="persist_1.img" label="persist" num_partition_sectors="9608" physical_partition_number="0" start_sector="10485760" />
[FROM HERE REMOVE "persist_1.img" ] THEN SAVE THE FILE
**NOTE- REMEMBER IN WHICH FILE YOU MAKE THE CHANGES.
(either rawprogram_unsparse or rawprogram0).
**NOTE**
Make sure USB debugging is turned on from developer option,
Now boot your device is in EDL Mode.
To Boot in EDL Mode just Power OFF your device and then press (volume up + volume down button simultaneously) when 10or. logo popup just connects the data cable... and your notification LED will start blinking...
**MAIN PROCESS**
**FIRST NEED TO FLASH V82 FACTORY FIRMWARE FOR UNLOCKING BOOT LOADER.
Now open QPST Tool/ QFIL Tool, anyone you prefer then select Flat Build then in programmer path, go to browse and from the V82 firmware folder select "prog_emmc_firehose_8937_ddr.mbn" file Then click on load XML And select the .xml File in which you have made the changes (otherwise if you select the wrong .xml file the IMEI will be NULL) After selecting the .xml file another window will be popup just select the [patch0] and then it's done...
Now you can flash your 10or. Device By just Clicking on the Download Button.
Let the flashing process to be finished...
After the flashing complete boot your phone it will show a start option just start it by power key, then your phone will boot into test mode then just click on Reboot --> Reboot To Android --> Ok, then again click on start by the power button, after the phone boots again enable the USB debugging option and power off your device.
Now we need to boot our phone into fastboot mode for that (press power button + volume down simultaneously) and then click on start again by the power button. then some options will be shown just select fastboot mode by the volume rockers and the power button.
As now your device is booted into fastboot mode just connect the USB cable and you can now unlock the bootloader by typing this commands
OPEN FASTBOOT/PLATFORM TOOLS and use this following commands
fastboot devices
(it will show if your device is connected or not)
then type fastboot oem unlock
then there will be a popup on the phone just select "yes" by the volume rockers and power button.
After the phone reboot, your phone bootloader will be unlocked Now you need to flash the V99 rom for that just power off your phone and boot it again to EDL mode and flash the V99 rom by the using same process use to flash the V82 ROM.
**Recovery Installation**
Now you have unlocked the bootloader and installed the V99 ROM now the final process came to install any custom recovery you want for that just extract the AIO Tool kit (password for extract: vishalsmagic) just open the file and go to the TWRP kit section then from flash section select the one you preferred to flash then just Double click on "VISHALSMAGIC" and enter password (vishalsmagic) then just type the com port no. and hit Enter to flash.But before flashing make sure your device is in EDL mode.
After the flashing complete just press the (power button and volume up) to boot into twrp..
And boooom you have installed custom recovery on your 10or.E
If you want you can install "no verity opt encrypt'' zip(optional) and "Magisk" for Root (optional).

can you explain why we are again flashing V 1_0_99 stock rom.
could we have not unlocked bootloader by flashing V 1_0_82 only.

Please, update link for AIO Toolkit.
