I tried to read all pages but could not find the answers to my questions.

- Downgrade to Android V9 - Howto ?

a) put a MIUI firmware in downloaded_rom and update with "System update" ?

Which firmware version where from ? Remove compability.zip from the firmware and modify updater-script?

Is there a ready-to-use firmware for that intermediate step ?

b) flash a MIUI firmware with fastboot. Which and how ? Is also a modification needed ?

c) flash a MIUI firmware with TWRP (which has to be installed before of course) ?

which global firmware could be used ?

Then the next questions are

1. Will the bootloader stay unlocked with a) b) c) ?

2. Which variant of TWRP is needed for the downgrade if any ? Sometimes CFW and sometimes not ?

3. After the downgrade is done how to go on ? Reinstall TWRP (CFW or non-CFW) ?

Thanks for somebody to put some light on it.

I tried the instructions but my RN8P is new with MIUI global 12.0.1.0 (QGGEUXM) and probably these instructions are no longer valid.

I could not boot into any TWRP recovery.

Flashing seems to work but not booting into recovery (boot loop).

So the phone boots to system eventually when i no longer press Vol+ and reinstalls the factory recovery.

Okay... so i saw a lot of people confused about what to do to downgrade.......

DISCLAIMER:: I am not responsible for u or ur phone's death :P.. At ur own risk buddy.....

Here's how to......

If you have miui 12/11/10 Android 10/9,,, If you have an older/newer/any version of the stock rom,,, (NOTE: if you are begonia/begoniai ,,, don't know about chinese,,,, BOTH ROM versions WILL WORK,, except u MIGHT face some problem with the other one,,, i tried global one in indian,,, didn't get much of a hickup.. and didn't try the other way around)...

1. Unlock bootloader.... (lot of tutorials on how to in yt/other sites). Though I once did flash without it and it worked,, it might just have been luck,,, So I strongly recommend u do unlock bootloader,, Don't blame me otherwise.

2. Download the miui fastboot rom u want to flash from any xiaomi stock rom providing website.

3. Install miflash Pro in ur pc (windows,,, don't know for other os)

4. Open miflash pro and open miflash, not sp flash tool.

Before that extract the fastboot rom to any place.. U should get a folder named begonia/in... something.

In miflash locate that folder and hit select / open or whatever was said there.

5. Once bootloader unlocked , boot your phone into bootloader ( while device is off Power button + volume down)

6. connect phone to pc with usb.. of course u need to have the proper usb drivers installed for ur phone. u can do that with miflash from some place... I forgot where.

7. Miflash will then recognize ur device as some bizzarre name. u have 3 options here.... Flash all and lock - will flash and lock bootloader again,, clean all save userdata - will save ur user data ,, like internal storage and apps and data,, clean all - will do , like a factory reset after flashing the rom ...

So after that,, ur phone should auto restart,, if not,,, do it manually,,, and ur phone will boot like normal,,, first time may take a while if u did clean all/ flash and lock.......

THERE ARE OTHER WAYS... BUT THIS IS THE CLEANEST WITH CLEAN ALL OPTION.... OR SO I THINK

For the other questions,, there are lots of guides out there in other threads... .......
[Redmi Note 8 Pro Guides, News, & Discussion] cruncher1234:
I don't think that will work because of the anti-rollback protection.

This guide still assumes android 9 on the Redmi Note 8 pro but newer phones already come with android 10 and the problem with the CFW mods is then that the new phones seem to have a different front camera and the CFW firmwares have no driver for it.

[Redmi Note 8 Pro Guides, News, & Discussion] YoureAnApple:
So of course i read about these issues after flashing Pixel Experience. Now i have at least a broken front camera.

Whats interesting though is my device shipped with 11.0.5.0 (PPGEUXM) while this post suspects the hardware change came from 0.7.+ builds (https://xdaforums.com/showpost.php?p=83570951&postcount=337)

Anyway im really frustrated as you can imagine.

tbh im really fed up and if i cant roll back that it is what it is. my device is 2 weeks old and i intended to use it...

any help welcome!

tyvm in advance :)

*edit: i installed 0.6. via miflash and am currently dl 12.0.3 Q.

i dont care anymore as long as all functions work. ill see what i can do about installing a custom rom/anti rollback IF there eventually is a solution to the missing drivers

Is my actuall profile set to flash any CFW ROM?

Before I read this instructions, I have already unlocked the boot loader, and I got root access (by Magisk), and I have installed the TWRP (Chinesse version 3.3.2b-0305), then I could flash MIUI 12 A10 Global. My question is: Do I have to make all this download process, etc. anyway, to set my Begonia as CFW, so that I can flash a custom ROM??... Or my actuall profile (unlocked, rooted, TWRP, MIUI12-A10 installed) is ready to flash any CFW ROM??

[Redmi Note 8 Pro Guides, News, & Discussion] big_lou:
To downgrade to a previous version, download the fastboot image for your device at https://xiaomifirmwareupdater.com/. In the archive you'll find the flash.bat or similar name. Open the script and remove the anti-rollback code or just use the flash commands manually (boot, data, etc...). In my experience, miflash was giving me anti-rollback errors and wouldn't let me flash so this is what I did.

So i was testing roms and in the process i managed to to do something wrong, but i don't know what. Ended in this situation:

TWRP works

When i clean flash any rom and reboot, it boots to fastboot

I tried cfw a10 and a10 roms, cfw a11 and a11 roms. It allways goes to fastboot on reboot

I tried the same procedure in twrp and orangefox :/

Anyone knows if this is fixable from recovery or fastboot, or i gotta go back to miui and start all over again?

Thx.

Edit: nvm, it's fixed. reflashed preloader, lk, and its good as new

Hello,

I want to stay with vanilla MIUI, I just want TWRP and Magisk is there an easy way to do this ?

I'm currently on base OS android 9 (never updated), is it a good idea to flash preloader as suggested ?

After I will want to update to A10 and then A11 (I saw that A11 was announced on this phone), with this modifications will I still be able to perform OTA update ? Does the "safe" preloader will still be present or overwritten ?

Thanks for any help
[Redmi Note 8 Pro Guides, News, & Discussion] donkyshot:
To install twrp and magisk you can follow this guide: https://xdaforums.com/redmi-note-8-pro/how-to/guide-unlock-bootloader-flash-twrp-root-t3995919

You can flash the preloader but it will only boot on Android 9. Flashing miui android 10 will overwrite it.

To update you can follow my guide here: https://xdaforums.com/redmi-note-8-pro/how-to/v12-0-2-0-qggeuxm-v12-0-2-0-qggidxm-t4180873

Remember to flash correct lr-twrp recovery for Android 9 & 10.

You can update magisk by magisk manager stable channel. Don't flash or update beta magisk 21, it's not working yet on mediatek.

If you have any questions, let me know, happy flashing.

I tried to search for my question, but I guess it hasn't been asked yet.

Is there any benefit to using a more recent CFW minor version than what the ROM developer has specified (e.g. CFW v3.2 instead of v3.0)?
[Redmi Note 8 Pro Guides, News, & Discussion] Novbidouille:
Good evening, I prefer to ask before doing something stupid.

I understood that you have to install the CFW to install a custom rom, but one thing bugs me, which CFW should I choose?

what does A10 and A11 correspond to ? the android version of the custom rom ?

begonia-oss - Browse /CFW at SourceForge.net

sourceforge.net

I just bought it and I'm on android 9, never updated, I would like to install Resurrection Remix OS.

Thanking you in advance, have a good evening.
[Redmi Note 8 Pro Guides, News, & Discussion] donkyshot:
Yes A9 stands for Android 9.

So if you're on A9 you can just follow this thread and install the preloader, cfw recovery and cfw rom.
[Redmi Note 8 Pro Guides, News, & Discussion] Naksnaks910:
Oh god this is confusing. Sorry for asking, but am I even remotely right when I intend to do this (currently on EMUI 12 A10 Stock):

Hi there guys!!!

I'm getting a weird bug, i can only install android Q(CesiumOS 2.6, or Resurection Remix, PixysOS 3.1). When i try to use any rom that uses CFW3.1 it bootloop to fastboot mode.. (tried orange TWRP, the unnoficial ones) nothing is change so far.. Any ideas? By the way tried to use TWRP-3.4.0.2 and flash cfw v 3.1 but it gives me corrupted zip when i try to flash in TWRP.

Any ideas??

Thanks for the help!!
[Redmi Note 8 Pro Guides, News, & Discussion] Naksnaks910:
Okay, thanks! Forgot to say that I alread have a non-CFW recovery (LR TWRP), so those files should still be good if I change the flashing order according to the post?

EDIT: Or do I still have to downgrade first?
[Redmi Note 8 Pro Guides, News, & Discussion] donkyshot:
For method one you need to downgrade first, for method two you can skip step one, as you already have custom recovery installed.

Read megathread but the solutions did not work for me, i'm probably doing something very wrong here...

Edit:

Ok i think the zip files WERE corrupt... download again "begonia-A11-CFW-vendor-20201128.zip" used OrangeFox.. installed and now when i try to install any A11 the rom bootloops... then go to recovery..

Hi I just bought this phone and im on the latest A10 - MIUI global V12.0.2.0(QGGEUXM) firmware. I really want to root it, but after seeing all these posts about permanent hard bricks im pretty scared lol. So just for reassurance:

1. Unlock bootloader

2. Flash this TWRP version in fastboot

3. Follow this guide to root with Magisk 19.4 (and afterwards upgrade to latest magisk)

If I do this, there should be no chance of hardbrick? Should I change steps? Thanks in advance! :)

If anyone has the files, we'll love to have them !

I'm ready to flash CesiumOS v3 coming from stock Miui11 A9.

If I understood well, I should first go to fastboot and flash the cfw files (preloader_begonia.bin and lk.img), then cfw-twrp.

Then, I should boot in twrp, wipe, flash begonai-a11-cfw-vendor, then flash cesiumOS.

Is that right ? No need to flash a firmware ?

[Redmi Note 8 Pro Guides, News, & Discussion] dedalumine:
Hello,

I would like to kindly ask for some help on some points, which I did not understood (despite some research on that thread). :unsure:

I just bought a Redmi Note 8 Pro, which is “waiting for unlock”; meanwhile, I am looking for information on put an alternate ROM. Looking that thread frightened me, I would possibly not bough that phone if I would have been aware of such “problems” (or potential problems)

I have some dumb questions here, but prior to do anything that may brick the phone, and as indicated in #1, I would please ask for some confirmations:$

My current MIUI version is MIUI Global 11.0.5 | Stable (PGGEUXM), and it is indicated for android version “9 PPR1.180610.011). Can I ‘safely’ proceed to the “CFW Migration steps” Method 1 indicated in the #3 ? (I expect yes)

I found there that CFW has issues. For me calls related (e.g. speaker) can really be a show stopper for me… Is it still the case?

Now more “general” questions, about the boot process. I tried to understand it better, according to some explanation provided there : https://xdaforums.com/t/info-understanding-and-troubleshooting-bootloops.4107637/ (sorry, but I don’t fully understood #1)

My understanding is that the boot process is BROM -> Preloader -> Little Kernel -> “kernel”

This last “kernel” could be either the boot.img (regular boot) or from the recovery. According to #1, I assume that the PL->LK->kernel chain should be “aligned/compatible” , and the PL/LK provided in #1 have their security disable (SLA), but only works with Android 9.

A) Are these assumptions correct?

B) Usually I flash using fastboot in “bootloader” more. I didn’t understand if this “bootloader” is present as in other devices, if it has its own “kernel” and in the chain PL->LK if the “bootloader” is after or not… May I ask for clarification there?

Now, looking into the CFW migration steps, I didn’t understood why it is recommended to first flash a “non-CFW recovery”, flash the CFW (from the non CFW recovery), and go back to bootloader and flash the CFW recovery.

Why this 'intermediate' step of flashing a non-CFW recovery ?

I have much more questions (mostly related to the version A9 / A10 / A11) but perhaps answers would avoid their need…

Many thanks in advance for any hints on points...
[Redmi Note 8 Pro Guides, News, & Discussion] FivEawE:
1. I think you are safe to proceed since if you were to look at couple of messages from this thread, they were mostly saying that the process was successful. I was on Android 10 and did the second method successfully.

2. I haven't noticed any issues.

A. There's a detailed explanation by the creator of the CFW on medium. If you google for "medium redmi note 8 pro" you should be able to find the article.

B. If I understood correctly, you are trying to guess if bootloader loads after MediaTek's EDL mode. If so, then yes. That's why if you brick you can't use fastboot (I think).

Regarding flashing the non-CFW recovery, I assume recoveries has their own kernel, which depends on proprietary blobs which reside in /vendor partition. Since CFW changes stuff in /vendor, there are two recoveries - one for stock /vendor and one for the CFW /vendor. I guess you can't boot CFW recovery on stock /vendor since there might be linking errors (these are just my assumptions).

If they are on the same Android and CFW version, then wiping system, cache, dalvik, flashing the ROM and formatting data should be sufficient enough.
