If you want unlock and install custom rom based on A12 firmware you don't need to donwgrade (just unlock bootloader ed install whatevwr you want)
you need to start from EDL if you want to install roms that require A11 framwwork

Thank you, so basically since my bootloader is unlocked I can follow instructions and just flash rom via fastboot? Color os doesn't have an option in recovery to install anything.

If you want to install lineage or other roms based on A12, just follow instructions
roms based on A11 tipically require A11.2.10.10 to flash it you should restart via EDL (MSM tool)

I've downloaded the msm tool and see nothing that it is catching

Solved, I had to find the right drivers, thanks for all the help guys

RQ: Links to Root Tutorial

Hello,
I am currently downloading 7.2.16 (MIUI8) Developer Rom for my Mi Max, so i could unlock its bootloader since i got the permissions to do so. I have a few questions for the time after i unlock the bootloader evenyually:
1. Can i go back to the latest stable global rom and still have my bootloader unlocked?
2. Can you give me a link to suitable TWRP/Root tutorial.
3. If i succeed with the flash of TWRP and Root, would i be still able to receive OTA updates.
Thank you.

ultimate / universal root / twrp installation guide?

Hi everyone
Sorry I am confused; there does not seem to be an ultimate universal root / twrp installation guide for the Xiaomi Mi A2 Lite phone (my son's phone) in 2019.
No offense intended but all these various posts on the topic just help to confuse people!
I managed to unlock the bootloader but can anybody please tell me what is the easiest / user-friendliest way to install twrp (which version?) and root the phone so that I may proceed with flashing LineageOS afterwards to get rid of all the bloatware.?
what about these partitions A & B?
Thanks a lot in advance
https://github.com/tkchn/daisyinstall/blob/master/README.md
This is the guide youre looking for
@barumbads: Thank YOU!
[EDIT] er... this is for flashing a custom rom!
I did some extra research out of XDA
[Guide] How to root Xiaomi Mi A2 Lite
and
How To Root Mi A2 / A2 Lite (Magisk) and Install TWRP Recovery
but again... confusing! which one should I go for?
(I already tried the later one and created another post following an issue with it!)

It depends on what you want to do.
Root doesnt need TWRP, just Magisk. There's a guide on here.
Flashing custom ROMs needs TWRP. Each custom ROM has specific instructions.
There's no one-size-fits-all solution for this phone.

Hi @a1291762 & thanks.
This is what I am saying it is confusing; I have been thru a few phones (samsungs, LGs, lately Xiaomi...)
and the process was first install twrp then root and then you could flash roms
I know when you flash LineageOS, you get root included in dev options so from your explanations I will look how to flash LineageOS but currently I'm struggling installing twrp as you have seen in my other post

My last phone didn't have A/B or encryption or use Magisk for rooting... So for me everything about this phone was new and different.
I started with stock (android one means I didn't immediately want a custom ROM). Then added Magisk. I added TWRP after edxposed caused me bootloops (magisk manager CLI can run from TWRP). I haven't installed a custom ROM yet but I've got a custom splash and bootanim.

OPPO A12 Root

Hey, I've been trying to root my OPPO A12 for the past few days. I tried almost every method I found on different websites, but it seems not possible to root this phone. I even tried to unlock bootloader and flash TWRP (I found out later that there's no custom recovery compatible with this device) but I can't load into fastboot mode. Pls tell me if rooting CPH2083 is possible or not, if yes I'd appreciate your help. Thanks in advance.

I did'nt tried because there is no profit of doing that as there is no custom rom or custom recovery for it you can only install magisk modules and voiding your warranty . I would port a custom recovery and then we can install a gsi im in the process of doing it

Rooting means gaining full acess on your phone and you do that for a specific reason and most of the reason is installing custom rom and if there is no custom rom then there is no profit.
And magisk is an app by which you can root your phone and install modules like viper4android which increases sound quality and other modules like that .
I would recommend not to root the phone. You can root after there is a custom recovery or rom

oppo a12 bootloader can be unlocked with the hydra tool. A new update comes from the hydra tool which claims that they can unlock the bootloader of oppo a12. You can see this by this latest update
Has anyone tried the hydra tool on an oppo device? I am looking into it. I hate my oppo because of the missing bootloader.
Sorry. XDA messed up. I did not want to post twice.

Question How to convert the T mobile 9 pro to the Global or NA OOS12?

Hello all!
I am an user of OnePlus 9 pro (T-mobile). I don't want the pink startup screen, and I found a lot of resources here can help me on it.
I have backup all my personal data. I have unlocked the sim and bootloader (using the official unlock_token.bin). What is the next step?
I am lost here since there are some different posts (and some posted last year, I am not sure if this still work or not).
Thank you all!
Flash a rom or custom oos
First off do not update to A12, make sure USB debug is enabled, auto updates disabled....do that and I hope you are on A11...if so, I have exactly what you need

I would stay away from custom roms, I have seen too many people having problems. Secondly as of right now, A12 is buggy so that is why I stay with stock A11 from T-Mobile. With the setup I can give you, you can have any custom bootanimation and custom systemwide font you want.....
First off, download and install Magisk v25.2 app from GitHub website and install it to your phone. Next download the attached file to the folder with your platform files.....
Download Magisk from this link to your phone and install it.
https://github.com/topjohnwu/Magisk/releases/download/v25.2/Magisk-v25.2.apk
Then download this link to your platform tools folder on PC...
Download twrp-3.6.2_11-0-lemonadep.img
Download page for twrp-3.6.2_11-0-lemonadep.img
dl.twrp.me
Then download this link to your phone storage...

Let me know when you are down with these three steps!!!!! And are you updated to 11.2.9.9

Yes. I have successfuly updated 11.2.9.9 now.
I have a question that would this work? https://forum.xda-developers.com/t/le2127-oneplus-9-pro-custom-rom-t-mobile.4490195/
I am interested in Android 12 or even 13 if possible.

If you are focused on upgrading to A12 or A12 then what I have will not work. As for the custom ROM, possible it may work, but you need to follow the steps to the letter. Any OP9P custom ROM will work from the XDA forums, the question is, will there be issues? Very possible. Good luck on your journey.....

Been running nameless for over a month and a half now and haven't had a single out-of-the-ordinary problem that can't be fixed with a simple reboot. I have the T-Mobile variant here. Data works fine.

Thank you for all the help today! I think I did something wrong. I successfully get TWRP (directly boot, not recovery since it is failed), and then get my phone bricked flashing the rom lineageos... Now I am trying to unbrick it...

Bricked as in black screen? Or does it boot to fastboot? What version of lineage are you trying to run? And what OOS were you on? You need to be on OOS 12 to run lineage 19. And twrp is not the recovery to use for that.
Look before you leap.....read read read and make sure to follow ALL steps 1step at a time.....

Question Where to get Stock Firmware?

Got the Mi 11 5G NE recently and I'm wanting to install LineageOS on it as per the installation guide: https://wiki.lineageos.org/devices/lisa/install
However it says I must be on Android 12 and unfortunately I've already updated the phone to the latest Android 13 MIUI.
Just wondering if there's a reliable place to find the Android 12 stock firmware

MIUI Downloader will point you to the official ROMs
MIUI Downloader - Apps on Google Play
MIUI upgrade app for Mi users.
play.google.com
However, you would need to avoid downgrade protection (it can be done, you will have to download the Fastboot type ROM, unpack tgz, find a bat script inside that does not relock BL, edit the script to remove downgrade protection and use it then to flash manually via Fastboot - not by using MIFlash)
Btw, for any flashing you must first unlock the Bootloader (either for downgrading MIUI and/or for installing the custom ROM)

Ah nvm it went through.
Can/should I re-lock the bootloader after either rooting or installing LineageOS? might just stick with rooted stock, haven't decided yet
