Thanks

When did the error occur? When u get into twrp the first time?

 

[Ahmedstony]

Yes, and I tried wiping cache and factory settings. Is the sdcard bricked? Any suggestions?

The phone is really great, but there're no custom roms or rooting options
Thanks

Yes I have the same model and version as you.

Actually tonight I received a system update to PB1-770M_S000169_151229_ROW however after updating it has the same problem when I try the .bat file.

I am wondering if my bootloader is locked. I bought it last month at the Singapore airport and perhaps their models are locked. How can I check if my bootloader is locked?

U can try this :

1. Set up ADB and Fastboot on your computer. You can download the full Android SDK from here, or get the quick ADB and fastboot installer from here. For Mac or Linux OS, click here.

2. Install USB Drivers on your computer.

Installation Instructions

Make sure you have setup ADB and fastboot on your PC. Also accept Always allow from this computer when you plug in the device for first time to enable USB Debugging.

Now connect your device to PC and accept the RSA Authentication prompt. Now open a command prompt or terminal window. Do this by holding shift key on your keyboard and right-click on an empty space and select “Open command window here” option to launch a command prompt window. Verify connectivity issuing the following command in cmd:
adb devices

Boot into the bootloader or fastboot mode. To do so, you can also issue the following code, while connected to the PC.
adb reboot bootloader

Now, as the Phab Plus isn’t recognized as a fastboot device, you will have to specify the OEM id. It is 0x2b4c meaning, any fastboot command must be suffixed with the following code.
-i 0x2b4c

Now this is important. We will proceed to unlock the bootloader. To do this, issue the following command. Choose yes on the device screen if prompted.
fastboot -i 0x2b4c oem get-device-info

If you see a message like (bootloader) Device unlocked: true, then reboot to bootloader
Bootloader on your device should now be unlocked. Reboot your device normally or issue the following command”

And start open the .bat file again :fingers-crossed:

Thanks so much for your help. I tried your suggestion on 2 separate computers (both W10) and got an error after typing; fastboot -i 0x2b4c oem get-device-info

However I tried a 3rd computer (running W8.1) and ran your .bat file again and it worked. I now have TWRP and root and I am now installing my favourite root apps such App Ops, Firewall and Hibernation Manager. I don't know why my 2 main computers had errors. I installed the correct ADB driver and used your files however there must have been some old drivers affecting the flash.

Anyway my new Phab Plus is now rooted and I very happy. Thanks so much for your assistance. I really appreciate it as it made me realize I should try another PC.

This is the Chinese version. When I run your bat file, I get success message (at least that is how I do interpret it), but the characters displayed make the echoes unreadable for me (wonder whether it has to do with the phone being Chinese).
This what I see (snapshot from UltraEdit of your bat file - the saem I do see when I run the bat file):
echo.

Any ideas why I can't read your echoes?

Could you copy them into this thread, so I can decipher what I am supposed to see?

Thanks

It is so nice that some one rooted Lenovo Phab PLUS, i was waiting for so long to get this. Now i want to get to home as fast as i can, and check if it works

Only problem i just get OTA that was around 30MB, i don't know could i root this device or not now.

Does any one know how to make Lenovo phab plus only in landscape mode, with no additional program like rotation lock ? Because it need to boot before it can rotate screen

 

[kilohercas]

This is what i get, and no mater what i press, i can't instal update via recovery. it says footer is wrong
