Mi 9 Restoring firmware

TLDR: I tried installing AEX rom and I bricked my mi9, getting it in a fastboot loop. Flashed a bunch of things and now I think my firmware is messed up. Help.
First I flashed TWRP, then I flashed the AEX rom and gapps, but phone got in bootloop, then I tried just flashing the ROM and it worked. After I flashed gaps it got into bootloop again.
Then I read the instructions from the AEX thread and I flash the recommended Firmware file (v9.6.13), and the flash failed.
I wiped everything, reflashed the ROM without gapps, and at restart the phone. Got stuck in fastboot.
Tried reinstalling TWRP with no success. Tried flashing MIUI with their flash tool but it didn't ended the flash procedure even after 20 minutes...
I tried to directly boot the recovery image (TWRP) and I was surprised that the phone booted in MIUI, but wifi wasn't working. Did not test anything else. Restarting the phone got me again in fastboot loop.
I tried again flashing with mi flash tool and this time was succesfull.
Then I tried to flash a MIUI eu ROM and got the phone again in fastboot loop. Flash was succesfull, but when restarting TWRP said that there is no OS installed.
I decided to give up and flash global MIUI 10.2.13 back.
But now my phone has some problems. Auto brightness doesn't work and video recording freezes the camera app when image stabilization is enabled.
So, is there a way to reflash 10.2.13 rom firmware using mi flash tool?
I suppose the first Firmware flash that was unsuccessful messed the firmware up...
Or how do I get my phone back to factory status...
I suppose v9.6.13 firmware is China developer and was an upgrade and that I should downgrade to 10.2.13 rom firmware.
Or flashing developer global will solve the problem? And how do I do that?

Have you ever tried fastboot rom ? Now it's the only solution to recover your phone !

Hmm, so where are you at now!? Have you got twrp installed? and 10.2.13 but with issues, right? or are you on stock recovery?

Current status: I managed to flash fastboot global ROM in mi flash, and stock recovery.
But the firmware is messed up.
Camera doesn't work well. And from normal use I saw that Gyroscope, light sensor and compas aren't working at all...
Phone reboots itself and I can't unlock it because pattern isn-t recognized anymore, untill I reset it by long pressing the power button.
From CIT menu gyro, light sensor and compass are definitely not working.
Would flashing latest firmware from TWRP be a possible solution? My bootloader is still unlocked and I can flash TWRP.
Or should I format vendor partition first? And then flash firmware?
Fastboot flash did solved firmware problem.

To be honest I'm not entirely sure if it'll help, but, I'd put global stable flashable zip on otg, then I'd flash twrp again, boot to twrp using buttons not commands, wipe cache, dalvik, vendor, system, data, internal. Then format data, swiping with confirmation 'yes'. Then flash latest global again over the clean device from otg. You could try using mauronfrio's twrp 3.3.1-35 instead of the one you linked get it here. That's just what I'd try, can't say whether it'll help and no guarantees it'll fix anything... Let us know the outcome bud.
You can download the latest flashable rom from here
I can't see why ur sensors etc aren't working anymore, it's got to be all software related me thinks
Do not try to reboot after wipes, you'll have nothing installed

Correct me if I am wrong, but flashing a stock MIUI zip form twrp won't work.
Or you are saying that I should flash a xiaomi eu ROM?

Got another sugestion:
Someone said that there is the posibility that mi flash didn't flash persist partition and that I should try to force flash it.
Referred thread here: https://forum.xda-developers.com/re.../how-to-flash-persist-partiton-redmi-t3830310
Is this a possibility?
And shouldn't mi flash reflash everything?

Hold tight bud, just checking. I remember doing that - and the stock rom flashes but you no longer have twrp, it flashes the whole system/vendor including recovery. But hang on 'cos I might be recalling my pocophone F1 for that proceedure. The reason I suggest to reflash twrp is simply to have better control over a fully clean wipe, before progressing to flash rom again. Like I say, hang on just checking...

Yes, miflash should flash everything, but you say you started flashing other stuff when it all went wrong, so I'm really not sure what's happened to ur device. Hang on anyway, still checking on the flashable zip ..
---------- Post added at 09:06 PM ---------- Previous post was at 08:49 PM ----------
Nope, I think you're right, it was the poco I was getting muddled with - haven't had to do this in while (poco has flashable stock zips somewhere...). It is possible to do it with lazy flasher, but that may start getting messy again. Have you tried re-flashing fastboot? Can you wipe much at all in the stock recovery - again, I can't remember.
Failing that, yeah, I'd seriously consider flashing twrp and flashing mi-globe or eu rom. I prefer mi-globe (although currently using beast rom) over eu simply because you can customize it more on the website. Though, I wouldn't recommend pre-rooting it. Root after, if need be. Any way, we'll cross that bridge later... For now just try to re-flash

Didn't get this.
Is it ok to format vendor partition? will it be recreated wen flashing again? using mi flash or from twrp?

I'm pretty sure you won't be able to wipe much in stock recovery, but just wipe what you can and try and re-flash fastboot. Don't flash twrp yet. You could try downloading again the fastboot file, in case of any corruption. Hopefully on the second flash all will be well. But that said, it should've been OK on the first flash :/ in theory

just flashed xiaomi eu rom and everything seems to work now. All sensors are working.
I had to disable signature check, and i got an mounting /system error -> got the message that is installed without changes... whatever that means
And now in TWRP, I think, my files are encrypted without enabling it.
Will try other roms later.
Thanks for the help.

Mi 8 soft brick

Hi guys
Sorry for my bad English
My device was running Android 10
miui 11
After I accidentally used an application to raise the screen frequency to 84Hz
The devics did a reboot and then stopped on the fastboot logo
I tried to enter recovery mode but was back to fastboot mode
I tried to flash twrp via adb and fastboot but the method did not work and the device returned to fastboot mode
Finally I downloaded the ROM file global Version Android 9
miui 11 and when i flashed the system via "xiaomi flash tool " the operation was successful until it reached the end of the process it showed me an error and the flash failed
I restarted the process and noticed that the flashing process gives me the error when the download arrives at "flashing boot"
I searched a lot for the version of Android 10 miui 11 but I did not find
What is the problem!
Can anyone explain what the problem is?
Thank you very much
Edit : solved With the help of my friend and brother @tsongming thanks bro

You likely damaged the phone, myself and others have posted numerous warning about flashing mods to increase the refresh rate.
I would recommend trying the Flashall.bat method.

See this thread : https://c.mi.com/thread-2121755-1-0.html
Also, I read about some people getting past these recent issues by using a USB hub extender. These decrease the amount of power to the port which may be causing a conflict. Try other ports and only use a usb 2 port. Further, I would recommend temporarily disabling firewall and antivirus if all else fails. Worst case use another computer.
If this helps come back and let us know what finally resolved it.

You still have encryption on your device, use the tool all in one and install TWRP ( You may need to use a different/maybe older computer, I think possibly windows 10 is part of the issue. ( Because I have had this exact issue that you are having)
Install the tool, and update ADB but not the tool itself, there will be a popup, asking to update. ignore it or the update will be flagged a sbeinga virus ( Actually a Windows issue) However, yes the program is unsigned.
Use all in One tool to remove encryption from device and flash TWRP
Boot to recovery, immediately flash root, Flash Su if you must.
Reboot to recovery, then flash a recovery rom. the boot to system , may take up to 10 minutes.
use ports from the back of the PC and you may need to use a usb hub.

While its possible that you have a hardware issue. Unless the phone has been exposed to moisture, or exposed to a great deal of force I doubt that you have a hardware problem. Again, I too have had a similar issue, it's just took a while to finally get it working, in my case my computer was part of the problem, since you have fastboot the number one goal at the moment should be with getting TWRP recovery installed, and then root.
Did you happen to make any TWRP backups?
Hopefully so, specifically if you have a TWRP backup that includes the persist image files, you need to try flashing those to the persist partition. If you can successfully restore the persist image then try the flashall.bat method again.
Another option is to use QPST, but try the above first.
Edit
Finally, After re-reading you initial post. I had forgotten that you attempted to improve the refresh rate of the display. If all you can get is fastboot after following all of the steps that I have mentioned than I am certain that you have a burned chip. Ignore the people who claim that you can't fry the chip they have no idea what they are talking about. The chip can absolutely be fried. It's still worth trying a few more times, you could have just simply corrupted partition images. When you flash the stock rom, or even when using the flashall.bat method not every partition is over written.
@ahmadbasher
When you flashed the file to increase the refresh rate you likely overwrote a partition called DTBO, See if you can flash a Mi8 DTBO image to the DTBO partition. If you have the full recovery backup, you can extract the file from there. i need to research exactly how that file works and I will try to help you will getting the image if you don't have it in a backup.

No problem, after reading some various post on GitHub, CNX, and source android.com, I found out that the Mi8 DTBO is in the boot. Image.
So you should be able to flash a boot image, root, and then recovery and hopefully boot to TWRP.
If that doesn't work then send me a pm and I will share my personal dtbo with you privately. But again you shouldn't need mine since dtbo is nothing more than the device tree and the boot image should suffice, because it has the exact same file.
ADB command : fastboot flash boot c:\boot.img

No that is just encryption, if the issue was related to encryption the flashall.bat method would have resolved it.
If you had a persist issue, you would see specific messages about not being able to mount the persist partition.

Yesterday I flashed the pixle rom on the device and I took off the device without problems but every period of time the device was doing a reboot, I do not know if it is the problem of the ROM or there is something wrong with the device
I tell you so that you know only that
Now I will flash the latest version of miui 11 android 9 global version, and flash the boot.img and then Root and finally Recovery True ?

Hey sorry for the delay in getting back to you, I sent you the link for the file via PM.
Also, I would strongly suggest using the stock miui initially. Just until you know it's resolved. Also while Miui is installed make a full TWRP backup and save it to your desktop. This way you always have a full backup to resolve any serious issues.
Then once you know everything is working as it should then go back to what you prefer..

For the record this issue was solved. Anyone reading this, make sure that you have a full working TWRP backup of your working device, it will save you a lot of headaches. The solution for the refresh rate is issue is restoring stock DTBO, and then flashing Miui Stock.

Question Can you install/flash the same MIUI version onto your phone?

So my RN10Pro is running MIUI 13.0.8 . Is it possible to download a MIUI 13.0.8 ROM from the Mi website and flash it to "Reinstall" the os?
Also, does this method need extra things like TWRP or is the unlocked MIUI bootloader enough?

You can reflash yes, I tried it before but on a different phone. I think you can do it in the Updater in settings too, I did mine in twrp by flashing recovery rom and doing a format data because of encryption. But to be sure (and avoid any errors), use fastboot flashing instead. It will wipe the data so be sure to backup.

So to be clear, it needs the unlocked bootloader right? Guess I have to wait 7 days :/

You can relock it afterwards if you're not planning to do any modifications or move to a custom ROM.

Question Phone Soft Bricked ?

Hi guys,
I was on "xiaomi.eu_multi_MI11Pro_MI11Ultra_V12.5.20.0.RKACNXM_v12-11.zip" (rooted with Magisk and with 2-3 modules), this Rom is from end of 2021 so I decided that I have to move on and give a try to "xiaomi.eu_multi_MI11Pro_MI11Ultra_V13.0.13.0.SKACNXM_v13-12".
First I decided to update my TWRP. I can't remember but I think that it was the one included in the v12.5.20 Xiaomi.EU Rom. I wanted to install "twrp-3.6.2_12-v5.1_A12-star-skkk.img".
First I removed PIN + Fingerprint and then restarted in Fastboot and booted with this kkk TWRP with "fastboot boot twrp.img", then I installed it with "Install Recovery Ramdisk", then rebooted to recovery (it was still ok) and finally rebooted to system ... and now it reboots in Fastboot.
I still have access to TWRP and I can see my files, so before I mess up more I'm backuping some files but it's f#£%ing slow .
What step(s) should I do to make the rom work again ?
I think of flashing Magisk-uninstaller (new TWRP told me at the end of installation that root was lost and that I had to re install it). Maybe there is something remaining from Magisk ?
Then, I think I'll flash "xiaomi.eu_multi_MI11Pro_MI11Ultra_V12.5.20.0.RKACNXM_v12-11.zip" again.
Do you have any advice ?
Thanks in advance.
P.S. : I know that I should post on Xiaomi.EU but I've tried to create an account on their forum since many years and it's insane but I used ~10 emails and I always have been detected as a bot or spam .

Always unroot before.
2 options:
Xiaomi eu rom v12 or 13, but you will need to format the data before flashing
Twrp/wipe/format data/type yes/reboot twrp.
If errors(red lines)repeat the operation.
Or use Miflash https://forum.xda-developers.com/t/flash-tool-guide-use-xiaomi-flash-tool.4262425/
In both cases you will lose your data.
You can try a backup with the twrp (without guarantee).

So nothing special, just flash and format data before if it's a different one ?
The simplest would be to flash again the Rom I was on ?

Of course but my answer was along the lines that it wouldn't work.

Flashed old Rom and everything is fine
So I'm back to the beginning .
Now I don't know how to move to last Xiaomi.EU.
Since kkk TWRP was ok to flash the old ROM, do you think it'll be ok to install last Xiaomi.EU ? Or maybe there is a better/safer TWRP to do it ?
And thx again for your support

Xiaomi Note 9 is still bootlooping even after installing stock firmware

Hello! Just created an account in this forum to seek help because this is driving me nuts.
I have a Xiaomi Redmi Note 9 (Merlin) which has no system (Android), but I still can access fastboot and recovery menu, so I went ahead and unlocked the bootloader and flashed MIUI without any issue. To my surprise, when I booted the phone back up, it was like I didn't do anything as it still bootlooped, it didn't even show the MIUI logo, so I tried again; still nothing.
So, I tried the following:
- I followed the guide in this forum for hard-bricked Note 9 phones (https://forum.xda-developers.com/t/...icked-redmi-note-9-merlin-hard-brick.4347025/), and I can tell the firmware flashes because the starting menu and the fastboot logo changed from the rabbit to FASTBOOT in orange letters, but still no system.
- I flashed stock firmware, but still no system.
- I flashed the MIUI version that the phone came with through fastboot, but still no system
- I tried to flash the newest version of MIUI the phone came with through TWRP using the recovery version, but still no system (and when I try to reboot, TWRP says there is no system)
- I tried installing Pixel Experience to see if MIUI was the issue but, still no system. The phone just keeps bootlooping endlessly.
- I tried running https://github.com/Zackptg5/Disable_Dm-Verity_ForceEncrypt to see if the encryption was the problem, but no progress.
I would appreciate any help to at least have my phone working, even if it's not with MIUI but with a custom ROM. At this point I don't care anymore, just want a useable phone.
Thank you.

Hi. Just flash the whole stock MIUI ROM of your choice and then
In TWRP you must format /data (you did first make a backup of your personal data right?)
Then phone should boot again.
I hope this helps. Good luck!

I've tried that a couple of times but it's like I didn't do anything, when I reboot I still get no system

bump - really desperate about this matter

I can't believe reflashing stock ROM + formatting the /data partition didn't fix your issue
You are using the flash_all.sh script that comes with the stock MIUI firmware right?
well your only option it seems is to check the bootloop log and then try to find out the reason for bootloop that way. Maybe somewhere inside TWRP you can find some kind of bootloop log? Good luck!

Yeah, I even tried with other PCs to see if that was the issue. Will try looking in the logs. Thank you!
