I have a Redmi 9 (lancelot, galahad) and I was trying to install lineageos for microg, but whenever I try to flash a recovery (tried with the one bundled in the lineage for microg zip, regular lineageos and TWRP) and reboot to recovery, the phone stays a while (20s to 30s) in the mi splash screen and then the screen turns black for another while, after that the phone boots into MIUI.
Edit: The version provided in the description of this video works, but I still can't install lineageos as it causes the same problem in the form of a bootloop.
Edit 2: I missed the Downgrade to Android 11 message, I repeated the process from MIUI 12.5.5 EU and now I have lineage porperly installed.

Hi everyone,
I'm new here though but am a Xiaomi user from the beggining of Xiaomi into devices with Redmi Note 3G Enhanced.
Currently, I own a Redmi 4X and I would like your expert lights please. I've flashed the latest twrp from twrp.me for my santoni device. Then flashed the latest build from LineageOS Official source + Gapps before booting up for first time. Everything was working perfectly until I decided to flash the latest update of LineageOS as I've seen in my updater it was released. So, I downloaded it through the updater and tried to flash it...
I came up with this "Failed to unmount /system (device or resource busy)" after that re-booted to LineageOS and everything was messed up with Google Services & Apps etc. Then I went back to twrp recovery and tried to flash again the rom but I was still getting that message so I understood something am doing wrong. Also santoni has dm-verity enabled which I know something about but just an info. I really wanna stick with LineageOS on my Redmi 4X forever but I'm afraid to flash it again. I've flashed MIUI 10 Beta by fastboot but now I wanna go back to LineageOS forever (addicted).
My only problem is: After successfuly flashing LineageOS and Gapps, I cannot apply (flash) updates to update the ROM to the latest nightly build due to this error above.
Kind regards,
peryson
Try with different recovery. For example with this

Instead of trying an unofficial recovery, do I have an option to unmount system manually before flashing through Official TWRP?

You can download latest Lineage OS build and dirty flash it (without any wipes) (so you can unmout system parition). And I don't see any issue in using unoffical twrp.
I also have experienced same error once during upgrade "failed to unmount /system"
Eventually I wiped everything and did clean flash from scratch. This is really annoying issue and demonstrates that upgrade system is not 100% reliable for some reason.
I'm not sure however is it Lineage or twrp issue.
Hello there, i unlocked my device and flashed twrp but everytime i flash a custom rom i get a black screen, mine is Mi 9T pro global, tried los 17 flashed firmware global 10.0 then los then gapps then dfe and restart got black screen even twrp got black screen, again i tried but changed gapps this time booted then i decided to go to havoc 2.8 i download firmware global 9.0 then havoc then gapps (download them from opengapps) got black screen after that i had to flash miui via mi flash tool , can anyone pls guide me on how to flash Custom roms(pie and Q) on my device,
Any help appreciated
The issue I have is that I am unable to install any custom rom in the phone, I am only able to correctly install xiaomi.eu roms and also miui global roms using fastboot method. Any custom rom I try, like Pixel Experience, but also many others, the phone will boot loop. Tried android 10 and android 9 roms, also tried to flash roms coming from an older global miui rom, just like one tutorial recomended to do, but still nothing. In TWRP there are no errors, rom seems to install correctly, but when I reboot the phone it will boot loop.
Another weird issue is that only some versions of TWRP will install on my phone, right now I am using Orangefox 10.0.3, version 10.0.4 just won't install, I flash it but nothing happens. TWRP versions from mauronofrio won't install for some unknown reason.
I'm at a loss really as to what is happening.

1. Try the latest OrangeFox beta - https://forum.xda-developers.com/mi-8/development/official-orangefox-recovery-project-t4039531
2. If you have any issues with it, then report (with logs) in the OrangeFox thread.
How?
I tried with twrp and orange fox, now is bootloop why?
When I install any zip custom rom, starts and android that something still stops responding.
And when i flash android 11 system image twrp says no os installed
After some time I got a second Axon 10 and I spend some time figuring out what was possible with this phone in terms of root, custom ROM etc.
My results are as follows.
What is working:
Android 9 + Magisk and TWRP
Android 9 + TWRP + Custom ROMs (LineageOS 16 and patched GSI)
Android 10 + Magisk and TWRP
Android 10 + Magisk and MicroG flashed via Magisk (= stock ROM without Google Services)
Android 11 + Magisk
What is not working:
Android 11 + Magisk + TWRP (TWRP logo flashes randomly but TWRP does not load).
Android 11 + Magisk + MicroG (the nanolx patching script does not work with Android 11 as of yet)
Encryption in Custom ROMs
Method to flash files via EDL
Unzip / unrar my files into the backup\full folder of the EDL tool and choose restore + full in the tool.
Unlock Bootloader:
Before you try any of the files, you MUST unlock your bootloader!
BACKUP of your data as it will be lost!
Download the EDL tool from this Thread
If your phone is not on android 9, you must go back to Android 9 first. e.g. by using my Android 9 1.9 backup.
After you restored it, restart while holding the volume + key and do a factory reset / format data.
Boot into EDL again and unlock the bootloader.
Now you are on android 9 with unlocked bootloader.
From here you can follow the other guides in the form and install TWRP or lineageos. Or flash one of my files below.
Flashing EDL files:
Unzip / unrar my files into the backup\full folder of the EDL tool and choose restore + full in the tool.
I put all my files into this MEGA account: MEGA
Android 10 version 2.9 Magisk + TWRP
Android 11 version 3.5 stock
Android 11 version 3.5 Magisk
Android 10 version 2.10 stock
Android 10 version 2.10 Magisk (TWRP can be flashed with Magisk)
Install MicroG:
Only works on Android 9 and 10.
Before you install MicroG you must patch the stock ROM to allow for signature spoofing.
The patcher script I used is on https://downloads.nanolx.org/NanoDroid/Stable/ When I write these lines the up-to-date-version is NanoDroid-patcher-23.1.2.20210117.zip
Reboot.
Install MicroG from the Magisk repository.
After a restart there will be error messages that google apps keep crashing. With each warning, disable the apps one by one.
When you reboot again, no errors should appear and MicroG should report that it is fully working.
You can add the Bromite Framework and give F-droid system rights. Both are available from the Magisk repo.
Updates will likely install the Google apps again and uninstall Magisk...
Revive phone:
Not really related, but I bricked my phone several times.
If your phones does not boot anymore or hangs in a bootloop, try accessing the EDL mode.
The easy way:
Boot while holding volume -
The hard way:
Old Volume +, volume - and power until you end up in EDL. The screen will be black, so it helps if you have the Phone connected to Windows and can hear the system sound when the USB sees a connection.
In anyway you can then use the EDL tool to restore / flash an EDL image.
On custom ROM support:
Well there is LineageOS 16 by Unjustified Dev. https://forum.xda-developers.com/t/rom-unofficial-zte-axon-10-pro-9-lineageos-16-0.3992127/ It works well. But has a patch level that is outdated by now.
On top of it you can install the GSI ROMs created by Rafyvitto. The latest one is Resurrection Remix https://forum.xda-developers.com/t/...nofficial-resurrection-remix-q-8-6-7.4172527/
with a security patch level of mid 2021. Which is recent enough to use. The stock roms are not much better.
With both Custom ROMs, encryption is not working which poses a privacy/security risk when your phone is stolen. Do not forget that your phone does not only contain your photos and data but also your passwords to your accounts.
Added Android 10 2.10 files.
Its nice to see anything new for this phone. I wish I can use these roms but I have the American version.
Hi and thanks for your work and your files.
I'm stuck on "Loading the programmer: prog_ufs_firehose_sdm855.elf >>>", if I try to recover your edl files with EDL Tool, v 3.25.
I have to choose option 2: "Restore Full EDL from backup", right?
Is there a way to check if the bootlaoder is really unlocked?
Thanks in advance
OK, I was able to solve the problem with the "programmer" and try the backups. The next step was almost clear. The device is stuck in bootloop. I've already tried all the backups I could find on Mega. After the EDL Tool has done its work and the device has restarted, the mobile phone goes into the boot loop. And now? So the starting position was: Android 9 with an open bootloader. Maybe someone has an idea?
After I couldn't get the device out of the bootloop, I flashed the A2020G_PRO_V1.6_FULL_EDL via MiFlash and then did an OTA update to 1.8.
Then I tried unlocking the bootloader again, which unfortunately didn't work. The flash is carried out without errors, but the device then apparently does not start in the desired Fastboot mode.
Thanks for your guide. However am I missing something with the Android 11+Magisk installation? I restored all the correct files and everything flashed correctly, however upon reboot there is no Magisk installed anywhere. Did a factory reset after the flash and still not there. Tried installing Magisk via his github and tried patching the boot.img again and it says success but after rebooting it says Magisk is not installed.

Maybe you need to switch the slot in TWRP. It sounds as if you install it to the other slot (like A) an then boot B. Or vice versa.
