Downgrade from Android 10 to Android 9 - Asus Zenfone 5Z Questions & Answers

Hi guys,
I installed Android 10 via OTA but it is full of bugs. I want to go back at 9 which was perfectly stable.
Is there a way to downgrade from 10 to 9 without losing the European warranty?
Thanks :highfive:

I haven't tried this, but downloading the previous full system zip from ASUS and using adb sideload from ASUS' recovery should work in this way, I could be wrong.
Edit, I tried this ^^
Didn't work, perhaps follow this guide: https://forum.xda-developers.com/zenfone-5z/how-to/guide-zenfone-5z-how-to-root-downgrade-t3815877

Use this file https://dlcdnets.asus.com/pub/ASUS/ZenFone/ZS620KL/UL-Z01R-WW-100.11.162.111-Downgrade-user.zip

Honor 6X - US Version (BLN-L24) - Initial firmware

In the tradition of the firmware threads by @vsriram92 ... here is the full initial update zip.
Honor 6X (US version) model: BLN-L24C567
Firmware: BLN-L24C567B110
Updated Link 2017-09-09 MEGA-FULL-OTA
Rollback Package from Android 7.0 to 6.0: MEGA-ROLLBACK
You can also download both from Huawei at hihonor.com in their support area.
Thanks @adomol, repository updated with appropriate credit.
Is this the Android 7 update from the 6.0.1 ????
No, this is the stock Marshmallow firmware that shipped with the 6X.
Can this be used to downgrade from Nougat to Marshmallow? Or will it brick? Just figured I'd ask before I try, I'm stuck in a bit of a jam right now, and no firmware I've tried will apply successfully (fails at 5%). So I figure that I might have better luck going back to the stock MM that the device came with.
Edit: It looks like the download link is invalid. Any mirrors?
Both links are not working now

Go to officail website http://www.hihonor.com/us/support/index.html
You need to install the rollback package before you install the 6.0 firmware if you are downgrading from 7.0

Thanks guys, but I was able to go back to MM yesterday, with the help of private messages from @adomol. It involved using a small rollback package and a large full package. The rollback went fine. I may or may not upgrade back up to Nougat, got some prep work to do and things to test. I've only had this device for a few days so I don't know the ins and outs of upgrading/downgrading firmware on Huawei. I'm more familiar with Samsung and Odin.

It is good that you downgraded to MM.
You'll get used to honor devices pretty quickly.
All the best

Can you share the links for small package. I will update the thread so that any othwr user facing the same issue can downgrade.
Link for only smaller file is ok but you can share both.

I acidentally deleted all files of blnl24, can i fix with this
Does anyone have the OTA firmware for the Honor 6x LN-24? All the links I'm finding online are broken.

[GUIDE] How to install EMUI 9 / Android 9 Beta on EML

Hi,
you want to flash EMUI 9 Beta, are FRP and bootloader unlocked and rooted? Great, here we go.
Disclaimer: I am not responsible for your bricked devices. This has only been tested by a few people with Windows 10 and EML-L29 C432. Other models may or may not work. Please don't use that method if you don't know how to recover your phone from a bricked or semi-bricked state.
It might be a good idea to disable your antivirus if you run into warnings. There is no root.
Steps:
- Download THE TOOL™ v0.2
- Download the matching firmware bundle for your device. With EMUI 9 the firmware files for L09 and L29 differ.
- Extract THE TOOL™
- Extract the firmware bundle, you'll get two ZIPs and some XMLs.
- Start FLASH.bat inside of the extracted tool folder - it will guide you through the procedure.
- I did not have to factory reset. Maybe you will still need to.
- I have no idea if you will be able to receive OTAs or upgrade to future builds.
Disclaimer: Its not my fault or my responsibility if you brick your phone. I have almost no spare time at the moment, so I will probably not be able to help you. Also, there is no root.
Download:
EML-L09 C432 - Build 9.0.0.47
EML-L29 C432 - Build 9.0.0.45
Massive thanks to:
- @Atarii
- @Androlark
- @ante0
- @dkionline
- @frantorresm5434
- laststandingdroid
- @mankindtw for the original NoCheck recovery
- @Pretoriano80
- @shimp208 for the bundled minimal ADB + Fastboot
- and of course to all the brave testers!
There is no root. Also, please don't blame if your device dies. And I don't know if VoLTE works.

Which model version do you have, C432?

yes c432
Will this work by sideloading the firmware with ADB (without root and unlocked bootloader)?
my phone is locked. So I don think this will work for me.
VoLTE works perfect!
No su message
The script always end with this no su error. I don't get the permantly grant root message.
I tried the script several times. But everytime the same error....
Any new info on possible root with this? Or do we have to wait till the full EMUI 9 release for that?

one way only huawei service center and flash by test point or all time update from funkyhuawei.club I have sam case
I already unlocked my bootloader and currently rooted on EMUI 8.1, got everything I need to do it with Android Pie. I've been looking into other ROMs like Lineage and AOSP, but I haven't found any good info for the P20... Only for the P20 Pro and Lite, which really sucks, it feels like the normal P20 doesn't even exist, a lot of forums only have subs for the Pro and Lite, it's very annoying.
What is stopping me, or anyone that was lucky enough to root before Huawei stopped that, from rooting EMUI 9? I don't have a lot of experience with android and roms so I'm kinda fuzzy on details.
Morning,
All is alright but... it is not possible to root p20 (some people explained same like genius but i'm not genius)
Where is the best method to root huawei p20.
Thx in advance have a nice day

Got it right. Used these files with instructions on OP
You must be on stock emui. And rooted. So first flash back your stich system.img en stock recovery. Then follow the tutorial in the OP.

Does rooting break OTAs?

Hey, a friend of mine recently got his Redmi Note 5 Pro and I was wondering if I can root his phone so that I can install google camera but without loosing OTAs. If I root the device, will he be able to receive OTAs normally? He is on latest miui 9.6 stable.
Thanks in advance.

problem will be recovery. theres redwolf and if am not mistaken also orangefox recovery that can install OTAS
If you simply want to test gcam than u can follow this guide. i have tested it and it works on both miui 9 and 10. and doesnt break OTA. i even got updated from global 9.6 stable to 10 stable while having this and all was ok. its the safest way u can use gcam without root or anything.

OP 7T downgrade from stable Android 12 to Android 11 [EU version]?

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.
