[GUIDES & FAQ][Merlin] Bootloader, Magisk, EdXposed, SafetyNet, GSI/Treble ROMs

[Akitake]

This guide worked for me. My both Redmi Note 9 are rooted with magisk v20.4
I've used the original vbmeta.img from Stock ROM.
But, I can't install Riru-Core and Riru-Edxposed using MagiskManager-v8.0.3.
It says to install any magisk version 19+. I've tried to bypass this verification, but it fails.
So, I've installed MagiskManager-v7.5.1 and I can install Riru-Core and Riru-Edxposed perfectly.
Magisk shows modules list perfectly.
Edxposed shows its installed and working perfectly.
I've tried to install XPrivacyLua and now it is working perfectly too.

Thank you very much

Very glad you enjoyed my guide, and happy it could help someone.
And congrats on following instructions properly, apparently most people can't.

And thanks for the heads-up with Magisk Manager!
I've added it to the guide as a temporary fix, crediting you.

My bad, I meant there's barely Xiaomi devices that shipped with Android 10, which have official TWRP.

Anyways, Both PBRP and TWRP I gave run fine, There's no specific reason that you would need an official build only.

I once nearly hard bricked my phone by flashing TWRP, it didn't boot into fastboot nor recovery so I'm trying to be careful

After I've installed modules using magisk manager v7.5.1, I've updated magisk manager to v8.0.3 and everything keep working perfectly. Root, Magisk, Riru, Edxposed and Xprivacylua.

SOLUTION:

At first run of magisk you need to have your phone CONNECTED to internet (wifi or mobile) ! Once it detects the Redmi Note 9 as version, it installs a custom patch for magisk manager can works perfectly. IT IS EXTREMELY IMPORTANT.

I can flash TWRP too, using this: http://unofficialtwrp.com/twrp-3-4-1-root-redmi-note-9

The question is, does the twrp work?

The question is, does the twrp work?

What do you mean with does twrp works?
I didn't tried adb sideload or flash anything.
But, I've tried file manager and terminal emulator, everything I need.
And they've worked as expected.

The question is, does the twrp work?

You'll have issues modifying system partition, wiping, etc.. but that's just due to the nature of the phone having Dynamic partitions.
Other than that, yes.

Is the recovery functional? Can it install images, zips, and etc?

I love customizations. But, I have to agree, there is no need to modify system.
if you need really to modify your system, probably you may need a pre-modified system.
I can live together all those unwanted applications from vendors.
They can be totally unaccessible with root.

Is the recovery functional? Can it install images, zips, and etc?

I am making alot tries and experiences with my new phone.
I will give a try for flashing zips.
There is any customized logo.bin for testing?

EDIT:

TWRP unnoficial is working fine on V11.0.5.0, but not on V12.0.5.0. I will give a try for v12.0.4.0.

As long as you don't flash TWRP/PBRP on vendor MIUI 12.0.5 and above, you're good.
Also make sure you don't miss out any commands.

 

[Communos]

Is the recovery functional? Can it install images, zips, and etc?

Yes, It can install zips which don't need system and vendor as r/w.

To test it out, I made a LineageOS GSI zip and flashed in recovery, flashed successfuly, no errors.

Very good to know, my friend !
I've just finished all my tests on V12.0.5.0.
Then, I will make some tests on V12.0.4.0 for last, because probably I will keep in this firmware version.

Never mind. I missed the fist command:
.\fastboot.exe reboot fastboot

after this step, I needed to update the fastboot driver.

Got the following error:

sending sparse 'system' 1/18 (131068 KB)...
OKAY [ 3.141s]
writing 'system' 1/18...

Phone: Redmi Note 9

You are doing wrong. If you are not sure for what you are doing, you have to use oficial flash scripts inside stock rom firmwares. This command "fastboot.exe reboot fastboot", makes no changes. Redmi Note 9 doesn't have system partition. You need to be sure for what you are doing before to do flash.

Phone shows fastbootd after the command 'fastboot reboot fastboot'.
Succeeded flashing CAOS.

There is a stock MIUI camera mod for custom roms called ANX camera, Give it a try.

I got 'can't connect to camera' error. Can you advise? Thanks.

CAOS on redmi note 9. Have tried ANXCameraUnity_190.BountifulDistantHapuka and ANXCameraUnity_181.SophisticatedTruthfulCob without luck.

Since Xiaomi released this phone kernel source, i hope we gonna get our official TWRP and custom ROMs soon

isn't it because of the mediatek chip? because it's closed source
