I've an Android 9 Snapdragon head unit for my Bmw f30.
I upgrade to Android 10 but has a lot of bugs and i want to downgrade but isn't possible to downgrade.
I can't get fastboot to work because USB and keyboard doesn't work.
I've my unit rooted with magisk.
It's possible to modify the necessary files (boot.img or wherever files are needed) and flash it in Android and then install update.zip (Android 9 rom) from recovery to downgrade?
Or modify the Android 9 rom to bypass the check that doesn't allow to downgrade?
Here are the Android 10 rom: https://mega.nz/#F!kbYFBS5C!gE-QFJoU...PxiJA!xXwSkQJb
And here is the Android 9 rom that i want to downgrade to: https://mega.nz/#F!kbYFBS5C!gE-QFJoU...PxiJA!xLJWECpK
Please, help me.
Thanks in advance.
help!

I purchased a head unit from Amazon from the make AmaseAudio, based on Opel/Vauxhall and with Android 10.
I'm looking to root but I'm a little confused on where to start, here's the basic details:
Model PX30
Android Version 10 (API level does show as 29 in CPUZ)
Build Number rk3326_mid-userdebug 10 .........
MCU MTCE_HT_V3.30_1
From what I gathered there is 2 custom roms for PX30 but they seem to be for Android 9, though my unit does seem to be running the real Android 10 so I'm not sure if it's possible to install either of those 2 ROMs or would it create issues with it downgrading or what would I actually lose by going down? I'd even be happy without a custom ROM but still have root access to disable a few services to speed it up but again I don't know where I'd begin.
Another question is I'm unable to find anything about the stock rom so no kind of backup in case of anything going wrong, is it possible to backup the stock ROM on the device?
I'm more puzzled since there's nothing regarding PX30 and Android 10 from what I can find.
some news?
Hi all,
I am new to all of this and want to try my hand at getting root for my Eonon GA9453B.
Android 10

I could only find one other post referencing MTK 8227L but not sure where to begin.
Many thanks in advance!
JPS

I have an Eonon GA9450B with the 8227L with the same processor
I was able to use the following instructions to get root:

I need help with rooting and getting twrp on android 11 OS. I know that there is no current version of TWRP working for Android 11 for Oneplus 8 Pro, however is there a loophole to get twrp on android 11 with no issues being on android 10 first and then rooting the device while on android 10 then flashing twrp, then flashing a stable android 11 OS build. Basically, I'm looking for a detailed list on steps I need to take to get the pixel experience rom to work on this IN2025 model phone. If that means downgrading to android 10 rooting it then flashing twrp then flashing a android 11 zip file through twrp and keeping root that way however I need to make pixel experience rom work I would like as much help as I can get.
There's a Pixel Experience thread in the development section for the 8P. There's also a link to a TG group. Install questions will be best asked there.
Hi all,
I have a Android radio PX30 with MCU : MTCE _KSP_V3. after I searched for the brand I found its effort&bj.
Is there a way to update it to android 10 or install custom rom on it?
many thanks
I have three videos on YT that show you how to upgrade. Two are free and the third is paid but probably the best method. The GPS slot method I won't include because it isn't recommended.
{Mod edit}
RKDevTool Method (USB)(Free and Safe)
ROMs Here.
Recommended ROM.
Both of these methods work for upgrading and downgrading very reliably. Data lost whichever method you use so backup with SwiftBackup then pull the folder to your computer.
I would like to know how I can root this Chinese radio and what twrp could I use since it comes with android 11 and I am not sure how to flash the twrp and what version is better, i'm not sure if I'm posting in the right section, sorry for the inconvenience, regards
