DISCLAIMERS:

This help is specific for MERLIN devices only !
(Xiaomi Redmi Note 9 and Xiaomi Redmi 10X 4G)
Keep atention. This is an UNOFFICIAL thread.
This thread was based on the thread by Agent_fabulous. Thank you very much !
DON'T ask by PM. If you have any question, reply to this thread.
Keep in mind, nothing is 100% perfect, so you need to read careful
and keep trying before to ask an already answered question.
Keep your backup files safe and secure ! If you can, encrypt them.
If you try to flash in "firmware upgrade" mode, bootloader will be LOCKED again !
Never try to flash in "format all" mode ! Otherwise, you will LOSE all secure and identifying infos for your device. Like IMEI and MAC.
Never try to share your backups or your security and privacy will be compromised.
USE AT YOUR OWN RISK. I AM NOT RESPONSIBLE FOR YOUR ACTIONS.
Sorry for my bad english.

GOOD LUCK

TWRP does work above 12.0.5, I have tested.

New build: https://tdrive.elytra8.workers.dev/image-new.img
Flash like you flash any other custom recovery.

For ADS in MIUI, using debloat tool and removing MSA does the job.

Uhm... hello, newbie here and hopefully in the right thread.

I have a Redmi Note 9 and wanted to install LineageOS. What I have done so far:

Jumped through all the hoops to unlock the bootloader.
Since that erases all user data, I did not bother setting a password in the setup. Just went through it as quickly as possible.
Installed TWRP 12.0.6
Used that to install lineage-17.1-20210209-UNOFFICIAL-merlin.zip from here.

Result: The new system does not boot. I always end up in TWRP again. Even if I specifically go to Reboot -> System, it'll boot into recovery. I think the first boot fails and then it goes into recovery (if I power the device off and on again, it vibrates, the logo comes on, the screen goes black, it vibrates again, the logo shows again, and then I'm in TWRP).

What I have tried unsuccessfully:

Flashing the vbmeta from here.
Erasing the misc partition.
Flashing the old lk from here.
Closing the AVB2.0 after flash (with and without closing DM verity).
Wiping cache, dalvik, data, internal storage, and cache before reinstalling LOS.
Replacing TWRP with PBRP and trying again.
Probably some other things I don't remember. I've been chasing red herrings through this rabbit hole all day.

I also tried to install the ArrowOS build (from here), just to have one more datapoint. After that, the device boot-loops into the bootloader, and I have to manually go into recovery via VolUp+Power. This leads me to believe that it's not the LOS build at fault. It seems more likely that I am a moron and am doing something wrong. I just can't figure out what it is.

Any help would be appreciated.

Uhm... hello, newbie here and hopefully in the right thread.

I have a Redmi Note 9 and wanted to install LineageOS. What I have done so far:

Jumped through all the hoops to unlock the bootloader.

Hey, Custom roms for Redmi Note 9 need MIUI 12.0.1 Indonesia, or MIUI 12.0.3 global vendor.
Downgrade your phone to the specific MIUI vendor, and then try flashing custom rom.

Here's the link for global 12.0.3

Xiaomi Firmware Updater

The ultimate script that provides firmware packages for Xiaomi devices.

xiaomifirmwareupdater.com

And before you downgrade your miui version, please erase system and vendor to bypass anti roll back.
Use these commands after connecting device in fastboot mode:

fastboot reboot fastboot
fastboot erase system
fastboot erase vendor
fastboot reboot bootloader

Then flash the 12.0.3 global/12.0.1 Indonesia miui version through MiFlash.
Or
You could give flashing 12.0.1 Indonesia vendor in TWRP, and then flashing rom.

If after fastboot reboot fastboot it shows waiting for device, install this driver. https://drive.google.com/file/d/1JFYCZ3mu_Y_xpnS7QrmtwqOeFnWg6DO2/view?usp=sharing
Please note that you need to be on stock recovery for fastboot reboot fastboot to work.

Happy flashing

Thank you very much! With that info, I think I finally have it working!

I case it's helpful for future users, here are some issues I encountered along the way:

Communos said:
fastboot reboot fastboot
fastboot erase system
fastboot erase vendor

Code:

$ fastboot reboot fastboot
fastboot: usage: unknown reboot target fastboot
$ fastboot erase system
erasing 'system'...
FAILED (remote: Partition table doesn't exist)
finished. total time: 0.013s
$ fastboot erase vendor
erasing 'vendor'...
FAILED (remote: Partition table doesn't exist)
finished. total time: 0.012s

Is that normal? I do have a partition named 'super' that I can see in the TWRP backup module. Judging from its size, that could be the system partition. I think there's also a vbmeta_system and vbmeta_vendor, did you mean those?

Then flash the 12.0.3 global/12.0.1 Indonesia miui version through MiFlash.
Or
You could give flashing 12.0.1 Indonesia vendor in TWRP, and then flashing rom.

Ok, so I downloaded the full ROM for 12.0.3 global. I'm using Linux, so MiFlash won't work. But the ROM archive I downloaded contained a bunch of partition images and a shell script that would flash them using the fastboot command. I just ran that script. Windows users probably could have run the .bat file that was also included. There were no errors. And after a reboot, MIUI started to boot and presented me with the setup procedure.

I did not complete the setup (I suspect it would have just auto-updated MIUI to something that would have caused problems again) and used the power button to go into the bootloader.

From there, I flashed TWRP again (since it got overwritten by the script mentioned above), went into recovery mode, and tried to install LOS again. First, flashing seemed to hang. The last messages in the log were:

Code:

Installing file '/external_sd/Download/lineage-17.1-20210209-UNOFFICIAL-merlin.zip'
Checking for Digest file...
Target: Redmi/merlin_eea/merlin:10/QP1A.190711.020/V11.0.2.0.QJOEUXM:user/release-leys

And that was it. The border around the progress bar was doing it's busy animation thing and after waiting for 10 minutes, I used the power button to reset the device.

The second attempt went through fine, and now I have LineageOS running on the device. I still need to play around with it some more to see if there are any issues, but the flashing itself seems to have worked.

Again, thank you for your help!

Oh you're using Linux, for Linux the commands is
/.fastboot reboot fastboot

Great to know you were able to flash successfuly. Note that first boot in all roms is a bootloop, you just have to force reboot after a minute of bootlogo showing up or so.

Apparentely, you need to flash in EDL mode.
So, you need to bypass the authentication in EDL mode first.

Newbie Android user here, hopefully i’m on the correct thread...i have a Redmi Note 9 with MIUI Global version 11.0.5 and Magisk version 20.4.

I tried updating Magisk to the latest version using the direct install option but I keep getting an error. I was told I need manually patch the boot.img and flash it but I need to create a magisk_patch.img first from the boot.img.

I read some of the guides on this thread but I’m not sure which one to follow. Also the steps to create the magisk_patch.image shows I need to click the Install button on Magisk then Select and Patch a file. I only have the Update button on Magisk, can I use that instead?

Or if you have other suggestion how to fix my issue. I attached the error I’m getting when I’m updating Magisk.

Thank you in advance for the assistance.

You can't install the magisk using the direct option.
You need to the patch the boot.img file and then flash the magisk_patched.img using fastboot (or spflashtool).

HELP PLS

i first flashed the patched_magisk.img then i got in a twrp boot loop. When i try to reboot into the system i get back to twrp menu.
Then i panicked and went to WIPE and factory reseted,
but it got stuck again. Then i powered it off.
How do i get out of this? I wanted to flash the stock boot.img but the storage folders has strange names

EDIT:
i figured it out what i have done. The data was ecrypted so i formated the data. But now i have another problem:
I installed linageOS from here, but when want to reboot back to system it says
No OS Installed! Are you sure you wish to reboot? i don't undertand why the custom rom didn't install.
I just copied the .zip file with the custom rom in the phone and hit install in TWRP. What did i do wrong?

no, i mean a full guide for rooting from the beggining to end, for redmi note 9. For example i missed the vbmeta and this resulted in an error. Now i have to flash the stock firmware and wait for another 7 days for it to unlock. For newbies like me, this looks like a mess. If you don't have one, can you please create one? Do it for us, newcomers. Thanks
