Question Lenovo Phab PB1 770m no operating system help

[pluto1956]

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
UPDATE I managed to get a ROM from Russian site PB1-770M_S000156_150930_ROW_fastboot.7z 1.8gig
instructions say to be installed from computer via usb my problem is I can only access the internal storage or external SD card not the Usb-otg so it seems I can only update from the sd or internal memory
tried putting the rom on both but no go

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.

How can you root this damn phones.... i was trying like for 2 days....

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.

i cant use the .bat cause my phone is already bricked...it wont be recognize by the app...the only way is thru QFIL but the problem is that i always get the error above

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?

I can't unbrick

Hi!

I have a Lenovo Phab PB1-770M, this phone won't turn on, only Lenovo logo, or fastboot or flashmode.
With Flashtool i can't flash. In Fastboot i flash a recovery or operating system, i reboot the phone and again only the Lenovo screen, operating system not starting.

What can i do?

 

[profeduards]

man dont use Qfil program.
the rom which you downloaded should be in zip format, unzip it, there is a file download_with_partiotion.bat.
run it and sit back until it is finished.

this is what i get running the .bat command >
'adb' is not recognized as an internal or external command,
operable program or batch file.

please ensure the phone can distinguish adb devices! Please retry!
