Hi Folks,

Seeing around various section of all the models when users are struggling to restore their phone either due the flashing an incorrect firmware or after updating via Firmware Finder app and then wanting to rollback to earlier version of EMUI. They sometime cannot even flash the custom ROMs due to FRP lock or unable to flash the custom recovery and even after trying all the known methods, we struggle to restore their phone as they messed up badly with their phone and model or version change to something unexpected.
In this thread, lets discuss and share about rollback files available for various models (be it MM, Lollipop anything) so that new users could use it to restore to their original version and then update to official versions.

Hi
Please NMO-L31C185 (Middle East region,GT3)
THANKS :good:

If it worked in past it should work again. Only flash file for your model.

Flash the stock Nougat recovery and then dload this file.
Else just dload the full Nougat firmware and then dload this. And then MM full firmware.

I too have the model nem-l21. I flashed Twrp did a whole backup of stock rom and installed lineage os. But I accidentally deleted the backup of the stock rom. I tried the dload way to go back to stock but it says incompatible with this version. What should i do? Before flashing twrp i was in android 7.0 and emui 5.0. Any suggestions? *Sorry for my bad english....

I will check and let you know soon!
So I checked the video.... I don't know if it is going to work... i will give it a try, thanks! I will do a full twrp backup. If it doesn't work i will be able to enter into bootloader mode and then flash twrp again? That's my thought...if it does not work i need to be able to enter into fastboot mode so with the help of twrp flash again lineage os... What do you think? If you can't find your device model then you are in very bad luck. However check the box that the phone came with (if you still have it). It has your devuce model. Also don't forget... choose the FULL OTA file from the site! ;)

Okay I have a question. I downloaded the rollback package and read the instructions. It says that you need to have a stock rom in your phone in order to do the rollback...so my question is. Will i be able to do the rollback while i'm on lineage os 14.1? I don't have a backup of my phone but have twrp installed. My phone is Honor7Lite/Honor5C NEM-L21! Please help! Thanks in advance :)
