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.

I could not find package file for L21 C185 and L24. I know there are links or comments on this, shared long back, but unfortunately could not find it. Please help in getting those and others available.
Files uploaded to Mega drive so that even if Huawei delete it, we still have the file.

Asking for this file?
I haven't seen this on forum and i couldn't get it from Huawei directly. They said it has been given to Service centre WTF (sorry for my words guys). They want us to visit SC for this (after spending on travel as well)
Package for L24 US model.

Hi Guys
How to get Stock Firmware Package for Huawei Nova 2i RNE-L22C675 ?? Can't find it any where. I need the Stock Firmware Package for Huawei Nova 2i RNE-L22C675 with EMUI 5.0??
I'm beginning to regret getting this phone cause there is literally no firmware support, neither from Huawei nor developers. Which is surprising cause it is came out the ending of last 2017. It's a real shame.
Anyways, if any of you guys have legit unbricking solution for this phone model would be much appreciated.
Thank you.

hi,can you help me downgrade back to emui 5.
i had issues debranding to oreo AL20.
im stuck in bootloop and lost my unlock keys for bootloader.
rollback package for BLL-L22 is not working
hi i have updated to oreo beta DUK-L09 8.0.0.321 (C636log) from the files listed in firmware finder.
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G2321/g1699/v110206/f1/full/update.zip

http://update.hicloud.com:8180/TDS/...hw_spcseas/update_full_DUK-L09_hw_spcseas.zip
Now I want to downgrade back to nougat.
I saw another C636 file which looks like the rollback package, "This update will roll back your phone's operating system to Android 7.0 (EMUI 5.1)."
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1997/g1642/v108624/f1/full/changelog.xml

When I try to use dload method, it fails at 5%, is there a nocheck recovery for oreo to help me flash back to nougat? Or is there any other way to flash the rollback pacake?
Thanks!
Here.

And: follow guide https://forum.xda-developers.com/honor-9/how-to/stf-l09c432-how-to-install-oreo-h9-t3707729 (it's similar to our device) and it has rollback guide.
You should be good to go to do a regular update with this recovery

why do you want to go back? are there any major bugs with the beta?
Bro. Going back to nougat from oreo is not yet available for this device. Google has changed the structure of all the partitions in oreo. So, until the company releases an official rollback package, you are stuck with it. I flashed the Oreo package after registering for the Beta testing version. I am using this version without any problem. I tried to call the call centre but even they are not aware about any roll back package.....
I want to share how I downgrade my MediaPad M2 8 from EMUI 4.0 to EMUI 3.1.
All my Google stuffs stop working after the B217 update.
This guide works for my M2-801W downgrade from B217 (android 6.0) to B019 (android 5.1).
*** Take your own risk! *** I take no responsibility! ***
In fact, I followed the guide here: http://cn.club.vmall.com/thread-11410111-1-1.html
I briefly write the steps in English.
Simply speaking, you need an "intermediate" update to allow your MediaPad to flash an old stock ROM.
NOTICE
This guide is for MediaPad M2 8 EMUI 4.0 (android 6) LTE version M2-803LC233B215 (or WIFI version M2-801WC233B213) back to EMUI 3.1 (android 5.1) LTE version M2-803LC233B019 (or WIFI version M2-801WC233B019).
Make sure your MediaPad M2 8 is original without custom ROM to reduce the risk!
Backup you data! This update will clear all user data.

Make a folder "dload" on your MicroSD card. Decompress the UPDATE.APP to the folder.

INSTALL UPDATE
Of course with enough battery level. Power off the device. Disconnect data cable.
Press [Power], [VolumeUp], [VolumeDown] at the same time for about 10s.
The MediaPad logo appears. Release the keys. The update will proceed.
Let the update process complete and the device will reboot.

Hey buddy, can you repost the "intermediate" update file?
Hey bro if your reason to downgrade from the b217 update is to get your Google apps to work again I recommend just installing an international 6.0 marshmallow update I will put the link here... this one worked for me cloud.mail.ru/public/E8YU/pjjUzCz1y
Simply just put the update.app file in a folder called dload on the root of your SD card power off then press volume up and down plus power button then it should begin the update all the best

If you have twrp recovery then just flash 9.6.2.0 fw less rom
Hi. I have a Redmi Note 5 (pro) Global version. I hate MIUI 10 too and want to roll back to 9.5.19 (which seems less buggy than 9.6.x) . Got the ROM from a great thread from miui dot com which I can't post being new here
The updater app tells me that I can't flash older versions
Recovery mode doesn't even offer flashing ROMs.
I can't unlock the bootloader now (have tried once, now have to wait 360hrs to try again??)
Am I stuck with MIUI 10?
THanks

Hi guys!
Just today, I updated my 7T [EU model] to the new, stable version of OxygenOS running on Android 12. However, I quickly realized that I much more prefer the old stable OxygenOS 11. Is there a way to downgrade to that version? I've tried scouting online, however, I only found downgrade links to Indian models.
Thanks very much!
Hi my friend!
Just check the official Oneplus forum (oneplus.net). There is a post OxygenOS 12 MP2 for Oneplus 7T/7TPRO that is pinned. There is a download link for all versions. Note that your cell phone will be erased!
Link: https://community.oneplus.com/thread?id=1181216999612088323&fromCircle=true
Thanks a lot, worked 100%
I just upgraded from 11 to 12, and i loose my connection every hour. Only thing that can bring back my signal is switch the phone into flightmode and back.
So will revert back to 11 as you did.
One questoin did the roll back wipe the phone or was apps and other settings still on the phone?

Is it possible to keep root through the rollback if I patch the boot image with Magisk before rebooting?
Edit: Just downgraded and had to root again after the downgrade (patched boot.img)
I am in the same situation. Upgraded to Android 12 and I'm having so many problems. I too am now downgrading. And actually moving away from OnePlus. Too many problems. Gonna try Carl's Nothing phone.
Hey there, Is it the original thread on offi OP site is not available anymore.
Do You guys remember the steps and what was needed to do the downgrade by chance ?
Help appreciated.
