Flashing chinese Mi9 issues and getting stuck in bootloop

Hi all,
So over the last day I have decided to install twrp and flash a new rom on my Chinese Mi9. Previously I have locked the bootdoader and installed the global rom. I have adb set up correctly and all relevant PC drivers.
So this is what I did and the problems I encountered. Hoping I can get some feedback as to what may have happened.
1 - Installed TWRP (mauronofrio) then it would get stuck on splash screen. Was told to install TWRP (LR.Team/wzsx150) which I did and it worked. I formatted and wiped my drive to get rid of encryption.
2 - I flashed EU rom (after editing script) using TWRP (wzsx150) then after install it would get stuck in bootloop.
3 - I installed TWRP (mauro) then installed EU rom and success, everything worked well. But I found with this EU rom, most of my apps would not install from play store or my Mi restore would not work, there were apps everywhere. Also EU rom was very buggy flashed it again and still the same issues so decided to go back to global rom. Too many apps would crash for no reason and even clearing cahce/data in app settings would not fix it.
4 - I flashed global rom on TWRP (mauro) and installed fine. But when restarted phone it got stuck in bootloop and couldn't get out of there. Had to use Miflash to flash the rom and start from scratch. I now lost TWRP and got Mi recovery back because of this.
5 - I flashed TWRP (mauro) again and tried global rom once again, flashed magisk etc and once installed rom, the thing got stuck in bootloop again.
6 - I now have flashed TWRP (wzsc150) and have installed global rom and it is installing and restoring fine. Once global rom has installed I have lost TWRP. I am also stuck in bootloop and can't get out.
So basically no TWRP works on my phone.
I have managed to flash phone back to original condition with the global rom. On a positive it still works and the storage is unencrypted.
Does anyone have any ideas or suggestions why my Chinese Mi9 doesn't like TWRP (mauro) and it always gets stuck in bootloop. I just want root access on my phone and google pay to work with unlocked bootloader.
Thank you

This seems to be the theme with 8GB version? I have this version too and makes me worried. I still have about 5 days till unlock insha Allah

These TWRP for Mi 9 are quite beta (no working decryption, no proper backup and restore for example).
If you want to have it, you must use custom rom like EU one.
Stock rom auto re-flashs Mi recovery, period.
BTW, I don't find any unbearable bug the EU rom (most of guys here also have no problem with it), just reinstall the app, backup program such as Titanium backup may introduce a lot of errors...

The apps were fresh installation from Google restore. Even when I deleted them and installed again they still crashed. Gmail, Waze and even checking software version in settings all made it crashed.
So now if I were to install twrp and euro rom again, it shouldn't delete my user data as I no longer need to unencrypt my storage right? Will euro rom just overwrite global rom and keep all my data

Do you think when I installed this rom I never did a wipe and all my apps were there on start up. Do you think this might be a cause of certain apps crashing?

...for example I have EEA variant and lastly using Global Dev rom. I still geting regulary updates even when I have TWRP (mauronofrio) and root. Only before every update I need flash stock boot and recovery. Then update phone and then flash back TWRP and Magisk. All the time working my old Magisk + Xposed (Ed) modules working without reinstalling them. Little out of topic here but just wanted to say

So with a custom rom like EU rom, everytime there is an update do you have to flash back twrp etc? Do the updates work OTA?

Rommco05 said:
I was talking about official Global Developer rom. To answer your questions. With EU you always need reflash Magisk for sure, if also twrp I don't remember. Yes EU have OTA updates but only full packages and need be flashed over twrp so all bloadware is back.

But when you flash back, you don't wipe the cache/data and lose all your stuff do you?

Ok, managed to flash to EU rom with no problems. Works great. Will updating with the updater delete my stuff?

Thank you for all your help with this Ted. It has helped a lot.
So I did the OTA update this morning successfully, but noticed before doing the flash in TWRP, there was a message saying it had to do it that way due to my device been encrypted. That's funny because I have formatted then wiped the drive before installing the rom. Is this a true message?

Always do a full wipe when flashing to a different variant of miui since current twrp has issues on decryption. I also had tons of problems from just resetting only without wiping data. For example flashing to eu from china stable everything worked from just doing factory reset. But google play cannot download any app that has an obb attached for some reason. Most likely problems with file encryption so i did a full wipe now everything works properly.

I'm not able to make TWRP work, its successfully install on terminal and when I reboot and hot volume Up key it bringing me to FASTBOOT mode, and if I do restart system, it and then hold Volume Up key, its again the stock Recovery.
My device is Chinese 8GiB 128GiB. any help will be appreciated. I want to install Xiaomi.eu rom as my current stock Chinese rom with google app giving me horrible battery life, standby battery drain is too bad.

You need to do it quickly.
After successfully installed TWRP in fastboot, hold power button to power off (it will restart instead of completely off), when the screen gone black, very quickly hold the volume up button, hold it until you see the twrp screen.
If you are not quick enough, the phone will boot up and stock recovery will be automatically intstall back, you have to start over: install twrp again.

can't flash TWRP 3.3.1 - 3.0.2 works just fine

I'm having difficulty getting TWRP 3.3 working on my z3c. I'm not new to the process, and have done it a few times on a few phones. Right now my z3c has TWRP 3.0.2-1-z3c. I'm wanting to try the new Android 10 ROM that came out, but it requires TWRP 3.3 to work. So I got the TWRP provided in the thread. I'm flashing from Linux, so I did run
Code:
./fastboot flash recovery twrp 3.3.1-1-A10.0-z3c.img
When I reboot and hold the power down button it skips over TWRP and just boots the ROM I have installed.
Okay, so I downgrade to TWRP 3.0.2-1 and reboot...hold volume down...TWRP boots just fine.
Flash TWRP 3.3 again....no joy. It just boots straight to ROM.

Same. Couldnt find a proper answer to this. Still have trouble with this? I'm on CR6.1, that's android 8.1 and I'd like to try later versions (lineage os or maybe CR7.0)

Screwed badly with the systems to the point where I softbricked the phone, and had to revert to stock. Will try going straight to 3.3.1 instead now.
Edit: I used adb to go to fastboot (adb reboot bootloader), from there I tried all the different twrp images I have, including latest Android 10 one using the fastboot boot image.img (replace image by name of image, I name them A8, A9, A10 to match android version).
All of them booted, which means I can flash them without issues. I don't know which version I want to install though for now, and I don't want to be stuck again on a version that I won't be able to upgrade later on... so will probably go straight to A10 and Lineage 17 even if it's quite buggy.

did you found a solution? i have the same issue...

stuck on "MI"

I'm on twrp and I can't install any aosp rom anymore. format "yes", install fw 0.9.0. start with the flash seems to be all right, reboot system and get stuck on MI and nothing happens, try again with another rom and it is the same. I returned to the initial state with XiaomiFlash, I install twrp, I redo all the procedures and start again as before. any idea about it?

if i install a rom xiaomi.eu with twrp the phone works, if i install a rom always with different twrp inside it does not install anything. It had never happened to me, the problem appeared after I tried xiaomi.eu 12 how do you suggest me to proceed?

Unfortunately you're not very clear with what you did. So I only can assume that you probably didn't flash vbmeta.

thanks tosca, I don't know how but I had used the wrong firmware ..., now all solved

Redmi Note 9 Bootloop to recovery - help needed

Hi all,
I have a rooted redmit note 9 that was running the stock rom (EU version i believe as i am UK based) perfectly well for several months until today when then latest over the air update installed and my phone is now stuck in a bootloop where i can only access the custom PBRP recovery (installed from when i rooted previously). I can also access fastboot. I have tried wiping all data and cache etc, i have tried reflashing the magisk patched stock rom that previously worked, i have also tried flashing vbmeta that i flashed previously but still no luck. This is my only phone so I really need to get it working again.
I was about to try re-flashing the stock rom with SP tool but it tells me the scatter file is invalid.
Not sure what else to try now. I also note that when i PBRP loads up it always asks for a password however i dont have a password on the device.
Please could someone suggest something i could try?

your devices is encrypted try flash other custom rom first then try revert to stock hope it help u out

Thanks very much for your response. Based on your advice i tried to flash the latest Kraken 11 Vanilla rom from this fourm, however after installing via TWRP now i can't even get into recovery anymore, just goes straight to fastboot.
Any other suggestions please?

I have now managed to get back in to TWRP and tried flashing lineage latest rom but still i am stuck in a boot loop taking me to fastboot this time.
Please can someone help suggest hwo i can get my phone working agian. At this point i dont care which rom i end up (custom or stock) with as long as i can get it to function again

If your device is rooted, you can NOT update the system using the OTA (over-the-air), or the device will be stucked in bootloop.
If your device is rooted, you need to update the system MANUALLY, using the fastboot or spflashtool.
I suggest to update the system using the fastboot.
Now, you need to flash the whole MIUI again, except userdata and you will have your device back.

For anyone with a asimilar problem i eventually managed to fix my issue by using miflash tool version 20180528 and flashing merlin_eea_global_images_V12.0.10.0.QJOEUXM_20210413.0000.00_10.0_eea_c4a9d5d7fc fastboot version which i downloaded from the xiami site.
I had to try this multiple times because the extraction of the file did not seem to be correct on the first attempts.

How to flash ASOP based ROMs?

Hi
A few months ago I was able to flash on angelica lineage-17.1-20210326-UNOFFICIAL-angelica.zip and this worked well. Yesterday I tried to flash the s same image again and after several attempts I get a black backlit screen when lineage is meant to start. I reflash stock _V12.0.10.0.QCRMIXM then a recovery - PBRP 3.0.1. From there I was having issue
What is the flashing process for an unlocked device that has something like TWRP/Pitch Back/Orange Fox installed?
I guess once you unlock and can flash the recover you use the recover to flash the zip, then reboot and flash magisk.zip and everything should work? Or is there some step missing.

I had this problem too with the google pixel 7 pro. Can't help ya there on that one. I even tried re installing older firmware and it still didn't work. Maybe the bootloader is permanetly downgradable but the firmware of the stock is. Just a guess. Lineage os 20 is an unofficial build at the moment that receives hardly any updates.
