Question Rollback Process - Realme C21

Sorry for this noob question
But there any way to Rollback to C.09 Update or Rollback to Android 10

There's a link to an Android 10 rollback package in the Android 11 announcement in the Indian community forums. That seems the easiest approach and according to smiley.raver in another thread you don't need to match Android 10 firmware with your region.
Alternatively you could flash some Android 10 firmware directly. You can find some links to downloads from realme on various sites such as realmefirmware that could you could flash with your favourite MTK flash tool. My choice would be mtkclient because I prefer to use Linux where possible but quite likely the choices for Windoze would be more user friendly.
Good luck! (I am a Noob too.)

Thanks for Reply Bro...

Is that right? I skimmed across the thread and didn't notice remarks like that. Anyway, I can't help you either way as I haven't tried myself.

No idea. Did I mention I was a Noob? You probably will find a guide to MTK flashing in one or more threads on this site.

Again Thanks for Reply
I will try myself

Backup all the partitions of your phone first and let us all know of your success.

it depends on the firmware file format
it also depends on if you have full firmware file vs upgraded file
can you provide a few more details and i can help out where i can.

Hi, I'm trying to download back to Android 10 to perform the region hack to enable the Dual Sim functionality from Australian Optus prepaid Realme C21.
But I'm stuck. I downloaded this file from the realme forums, talking about a rollback package.
RMX3061PU_11_OTA_0370_all_kpNiOQ0SFsQk.ozip
But as i follow the instructions it tells me, the install version is older hence wont continue. This is with the built in recovery method.
Mainly posts mention that the special rollback ozip can be used to downgrade but for some reason the recovery wont allow me.
I'm not clear as to how I can downgrade back to Android 10.
I know there are roms (how do I flash these??? do I need to unlock bootloader), then were are ozips which are realme stock roms.
So what is the best way to downgrade back to 10??
Just want to get back to 10 so I can change the region to the 'optus prepaid xxxx', to get dual sim.

yes please.
Could you share how you downgraded?
I've been looking at flashing it directly with the zip firmwares you can download. But the process seems complex and I haven't found a clear way to do it.
Just want to downgrade to android 10, change region then enable dual sim and then allow it to upgrade back to 11 and 12 I guess.

If you use telegram
Msg me on
@CRit_172
This ID
I cna explain there and can send You necessary files ..

I have a theory.
Use mtk-client to unlock bootloader.
Install twrp with all in one tool. (not sure if need to use auth bypass hacks).
use twrp to flash android 10 ozip.
then try to boot into android 10.
use region change codes to perform change.
possibly restore recovery to stock, then lock bootloader and use OTA or ozip upgrades to upgrade to latest.

[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.

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.

looking for factory images for nokia6.1

It would be great help to the community if someone could share factory images for this device of android 8 and 9. It can be use to reflash from scratch, or downgrade the device to android8 like me..
In most cases, what you need is boot, system or vendor images.

I need thos images which i could use to flash my device. Actually i want to downgrade to orio, as i am not happy with pie. Can u help?
still waiting for response
I am in the same boat, I want to downgrade to Oreo 8.0 so I can unlock the bootloader. I found this website where the firmwares are available, thanks to the owners but I am not able to downgrade because it either gets stuck on 'abl_b' partition or fails. I have tried to use OST tool 6.0.4 with slightly edited firmware as I found on internet.
https://fih-firmware.hikaricalyx.com/index_en.html
You need Ntool for downgrade ur phone.
Also here are stock images: https://forum.xda-developers.com/no...de-how-to-make-backups-restore-stock-t3889815
Same here. I updated to pie but unhappy with it due to poor battery life and stability. I want to downgrade too.
---------- Post added at 10:35 AM ---------- Previous post was at 10:29 AM ----------
I came across a downgrade method for 7 plus where you just need to change slot from a to b. Then you flash downgrade package in stock recovery by applying update (in reality downgrade) from sdcard. Ii doesnt need bootloader unlocked. search google "How to downgrade Nokia 7 Plus from stable Pie to stable Oreo" (not allowed to post link because the site sells bootloader unlock).
if we had an oreo downgrade package for 6.1 we could try this method.

If you are critical unlocked, you can downgrade via OST LA. If not, you need NTool for downgrade.
I also tried to adb sideload through recovery the Oreo update but it also didnt work because it said the timestamp is older than current one. May be if we can change the time stamp it would just flash the update.

I am not sure if it's actually from Oreo because could be Pie, but the file name is "PL2-3260-0-00WW-B01-update" and it's size is 1.42Gb. I found it while I was looking for stock firmware for my Nokia 6.1. I dont remember from where though.

This page Is from a senior member here on xda, however search your model and variant firmware, if you flash a firmware for other variant YOU WILL KILL YOUR DEVICE
Good luck me if you need further help send me a PM

Then download the firmware marked as PL2-347C-0-00CN-B04
On the bottom of the page there Is a tool called Generic flashing script (or somenthing like that)
Once you have downloaded both files uncompress the firmware un any folder and copy the tool on the same folder
Click on the tool icon and follow the instructions

Question How to convert LE2111 OP9 phone to EU ROM?

[Posting here since this forum seem a bit more active than OP9 forum.]
Hi guy. What are the steps I can follow to convert my Indian(LE2111) OP9 with Indian Oxygen OS to EU variant?
Wanted to get away from the bloatware in Indian ROM & EU variant seems to support dual SIM. Also want the US version of Gpay, etc.
I downloaded Oxygen Updater , changed device to OP9(EU) & downloaded the full OTA ROM. When I try to "Local Install " on Settings page it says "verification failed".
I also downloaded the LocalUpdater apk, which also fails.
I haven't unlocked the bootloader or rooted the device
What steps am I missing?
I have the same needs but for my OnePlus 9 Pro.
Try to follow steps I did: https://forum.xda-developers.com/t/...-chinese-variant-le2120.4269767/post-87447209

Thanks for responding. It's seeming like the process has changed a lot since the last time I flashed ROMs back in OnePlus One days. lol
I'm currently on LE2111(Indian ROM) C60 on Indian variant OP9(dual sim, no wireless charging). I want to move over to EU ROM.
So are the steps:
1. Downgrade to android 11 using MSM Indian tool.
2. Flash android 11 using MSM EU tool
3. Update from OTA/Oxygen Updater.

Or you could do it in simpler way: after downgrading to A11 with MSM Indian tool use Oxygen Updater and select EU device, in the app’s settings: “Stable (full)” update method and enable advanced mode.
This will let you download the latest EU full ZIP, which you can install via the system’s built-in “local install” feature or the separate local upgrade APK https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk
