Update from P2a42_S233_170404_ROW when OTA is not working - Lenovo P2 Questions & Answers

Hi,
My Lenovo P2 uses the stock rom in P2a42_S233_170404_ROW version.
I can't download any OTA updates, maybe because my phone is rooted and its bootloader is unlocked.
Could you please tell me how to update it to its last version, without losing any data?
Thanks for your kind help

It's Ok..

Thanks for your quick answer.
Unfortunately the S251 link is broken/offline.
Would you please tell me where I can find it?

Try to explain better! Do you have installed custom recovery?
no i installed a modified multi language rom from "needroom" did every as told and everything looked fine during the upgrade and when i was finished i got the green circle that says it was ok but when started it up it went in to boot loop and said "TOOL DL image fail!" but after a while its totally dead.,when i try now it wont load in any software into the phone ,just starts up the purple pre preparation on the SP flash tool but when i connect the phone it stops .cant get it into recovery mode or anything,just completely dead. i would rely be thankful for some advice her
Maybe the package you've tried to install is corrupted.
most likely, but is there anything to do with it or is it over for it.

Most likely your device is unusable. Without any recovery, I dont think you will be able to do anything. I am sorry.
OK a 200$ experience richer , thanks anyway

Are you able to be in the download mode for some time? Try to use DLM backup using lglaf to backup all your partitions.

I would find the stock firmware that you where on and try to flash lgup or flash tool and start again you will lose data but device will be working. And remember to always backup before hand.
First of all thanks a lot as your method perfectly worked , i just have another question out of curiosity if you don't mind , altough LGUP did work of course , i recently noticed that if you don't already have the Google account already registered on the device , and precisely on Lollipop and above , there's absolutely no way you would boot up your phone , i wonder if there's a way to bypass that Google Verification thing !
and just for reference , LG UP doesn't entirely flash the device , it just .... , you know , like just replacing the old firmware without deleting the data , LG FLASH TOOL 2014 doesn't work either , it doesn't even start the flashing process regardless of the firmware , so it's not an option .

Moto Z2 Force Sprint bricked *Please help*

Hi all! I ask your help! I have Moto z2 Force on 8.0 Oreo and I installed custom recovery twrp-3.2.1-1-nash.img and foolishly chose Slot-B and then I reboot the phone. Now when connected to a computer, it is defined as Qualcomm HS-USB QDLoader 9008 . How can I bring it back to life?! Help please! :crying:
After many attempts, it was possible to flash blankflash_from_NDX26.183-15_17. Phone reboot in fastboot and then full flash stock firmware.

This happened to me on t-mobile yesterday and I managed to solve it by downloading this: (T-Mobile only) https://drive.google.com/file/d/1fM5KLheeMYcs3yF7InOzHq6yGCOmrrbk/view
Extract the zip and while your phone is connected to your pc and booted in bootloader mode, run flash_all.bat, boot (don't flash) TWRP, install TWRP with the TWRP zip found here: https://dl.twrp.me/nash/twrp-installer-nash-3.2.1-1.zip.html
Then reboot to your newly installed TWRP recovery, factory reset, flash rom, reboot bootloader and run "fastboot -w".
After that you should boot up fine. Fastboot -w might not be necessary but I had to do it, otherwise I would boot but I would get an error message "android.process.media has stopped" without it.
Hello Friend!
Do you know if there is a solution for Moto Z2 Play? The update for Android 8 came automatically and I accepted. After a few days, he caught up and got into HardBrick! Neither the BootLoader options (power + volume (-)) are working !!
When I put it in the charger it will flash a white LED
Sorry, I'm using Google Translate
