Hi all,
Need your help, 3 days ago, I unlocked my bootloader and via TWRP from this guide, managed to install MI EU rom V12.5.7.0.RKACNXM to my CN Mi 11 Ultra. All seems fine in the beginning.
But since yesterday I noticed, I can't use my front camera from Instagram, and then tried camera app, and also tried in CIT test menu (press Kernel version repeatedly from Settings), all are not working.
in CIT test menu, when accessing front camera, it will just stay blank white. other rear camera modules works fine though, only front cam is having this issue.
Already tried restarting phone, reflashing the recovery image from TWRP, clearing cache, still the same issue.
Is this 100% hardware issue?
Any help appreciated.
Update:
I tried reflashing the mi eu 12.5.7.0 recovery image from TWRP and format data, front camera still not working
then, i go to fastboot, and use the official fastboot CN ROM flash_all (clean_all), after done front camera still not working
so i think it's 100% percent the hardware issue. i have to return the phone to the seller, i want to re-lock the bootloader first.
what is the correct way to do it? when originally flashing the fastboot CN ROM, i wanted to try "Clean all and lock (flash_all_lock.bat). but i was afraid it'll brick my phone if i miss any step in making sure that it's ready for re-lock. (e.g. TWRP still in inactive slot maybe? i'm not so sure if this is a valid case)
note: i'm using official fastboot CN rom 12.5.7.0 because my device is the mi 11 ultra CN version, M2102K1C.
Also worth noting, in CIT test, first test menu (check version info), Ese Memory Total is showing number 0 in red on this device, while my other mi 11 ultra device, Ese Memory total is showing number 1 in green

Mine is working fine. I also have the CN variant and unlocked my bootloader have have at varous time flashed all versions available. That includes the Global, EEA and Xiaomi.eu roms, both stable and weekly.
I would recommend, first installing an older Xiaomi.eu (12.5.4 from 4-30-2021) rom prior to installing TWRP and upgrading to the latest version available. Older Xiaomi.eu fastboot roms where developed before TWRP for this device was available. The bat file script will format your storage properly and install. Once installed and basic setup is run, upgrade to the latest by installing TWRP and flashing 12.5.7.
When flashing one of those fastboot roms, you need unlock the properties and then flash it using administrative rights on your PC. Do a search on documentation on how to perform this flash. You will probably find that information here or on the Xiaomi.eu site.

hi jim262, I've tried xiaomi.eu 12.5.7 rom and china 12.5.7 rom, issue still there.
i don't think it's the problem of the rom, but the hardware itself.
i have 2 mi 11 ultra, one for me, one for my SO.
mine has no problem, currently on mi.eu 12.5.7.
so now i have to return the other one, but has to relock bootloader first, so, is it safe to just flash latest CN 12.5.7 rom via miflash and chose "Clean all and lock (flash_all_lock.bat)"? I'm afraid of potentially bricking the device
anyone with expertise kindly help me out
in recap, steps i did:
#1 unlock bootloader
#2 boot TWRP
#3 flash mi.eu 12.5.7. format data
#4 use for several days, realized front camera not working
#5 reflash mi.eu 12.5.7 via twrp. format data. front camera still not working
#6 flash fastboot CN 12.5.7 via miflash, using flash_all (clean_all.bat), front camera still not working
#7 decide wanting to return the phone
#8 how to relock bootloader, is it safe to just flash fastboot CN 12.5.7 via miflash using "Clean all and lock (flash_all_lock.bat)"? is there any step i missed? (e.g. inactive slot still having custom mi.eu rom?)
Sounds like a hardware issue tbh
Can you get warranty replacement or exchange?

Just reflash original stock rom using (flash_all_lock.bat).

from what i read, relocking bootloader with the incorrect rom not shipped with the device will cause brick
while i know that the current rom i'm on is the one it's shipped with (CN ROM), and the fastboot installation that i'm about to do for flash_all_lock.bat is also the very same 12.5.7.0 CN ROM, I'm still not sure about the a/b partition.
will it still have the remains of the custom EU rom i installed previously? thus resulted in bricking the device when relocking the bootloader?
i have to be absolutely sure about this because if the device is bricked, i'll lose my money for sure, cos the seller will not accept bricked device to be exchanged. i'm in southeast asian country with no official support for this device.

Look at the box that comes with the phone. There will be clue where the phone comes from. The phone model can be a clue.
If you are sure it's from China, then flash official stable fastboot ROM without lock.
Re-Lock bootloader can be done separately after flashing ROMs.

hi, thanks for your reply,
my concern is not really to make sure that it's a CN model phone or not.
but my question is about the A/B partition when relocking.
yes i know this phone came with CN rom as stated by seller and i can confirm it myself, first boot, all chinese, some parts of the box are in chinese, no charger in box, and the device model is M2102K1C.
if you read the steps that i did, at 1 point, i boot TWRP via fastboot and flashed mi.eu 12.5.7.0 rom, twice even.
before i reverted back to 12.5.7.0 CN rom via fastboot miflash.
now to relock, i have to be absolutely sure no trace of mi.eu rom? is it still residing in inactive slot (because of AB partition), which will brick my phone when relocking even when official CN rom active slot?
that's what i want to know.

Still use fastboot to flash official MIUI ROMs.
Don't use TWRP to flash official MIUI ROMs.
As said, relock can be done once you flash the original official ROMs back into system with fastboot command.
If you have doubt, flash it twice or thrice.
If you are able to flash the official ROM back into phone and able to boot into MIUI with official ROM in it with the clean all option, then it should be clean.
The given link has info. Read it.

i read it, but it doesn't mention anything regarding a/b partition.
that's my real concern is.
i know i'm on the CN official rom that came with the device, but what about the inactive slot? will it affect the relocking of bootloader?

A/B (Seamless) System Updates | Android Open Source Project
source.android.com
If you are so worried about slot A/B, downgrade to Official MIUI with an earlier version, then do OTA update. Check ARB protection yourself before downgrade.
It will overwrite both slots.

ah okay thanks, that's one way to make sure both slots have the CN official rom.
i;m now downloading the previous CN rom 12.5.4.0, hopefully arb version is still the same.
but from what you know, even if not doing this, relocking will still be fine? no matter what resides in inactive slot?

I don't know if relocking is fine or not.
A/B slot works as backup in case boot partition failed in one slot, there's still backup in the inactive slot that is probably bootable. (what I understand reading the Android link.)
Theoretically if you are able to boot into the system, one slot is bootable.

ah i see, that;s why i hesitated to relock because of this a/b partition concern, cos i don't know what resides in the inactive slot, and if it's the custom one, i think there's a chance my relock of bootloader will fail.. if that's even how it works..

There's fastboot command to flash into both a/b partition, but it might be more burden for you.
This code checks which slot the phone is currently using.
Code:
fastboot getvar current-slot
The safe way is just as said, downgrade after you check ARB index and Anti version is safe to do so. Then OTA update.
How A/B Partitions and Seamless Updates Affect Custom Development on XDA
You may have heard of Seamless Updates before. It involves something called "A/B partitions." What is it and how does it affect custom development on XDA?

we can see above, flash modem_ab, bluetooth_ab, boot_ab. does that mean both slots already have the official CN rom?

I don't know.
In fact, I never had an A/B slot phone before.
Do what you think is correct.

from what i read, relocking bootloader with the incorrect rom not shipped with the device will cause brick
while i know that the current rom i'm on is the one it's shipped with (CN ROM), and the fastboot installation that i'm about to do for flash_all_lock.bat is also the very same 12.5.7.0 CN ROM, I'm still not sure about the a/b partition.
will it still have the remains of the custom EU rom i installed previously? thus resulted in bricking the device when relocking the bootloader?
i have to be absolutely sure about this because if the device is bricked, i'll lose my money for sure, cos the seller will not accept bricked device to be exchanged. i'm in southeast asian country with no official support for this device.

Here's the reality, Xiaomi allows bootloader's to be unlocked. If you bought this thru a third party retailer, I'm not sure what their policy may be. What did it originally ship with? It was more than likely the CN rom if you imported the device from China. All the stock fastboot roms can be downloaded at MiFirm.net. As one of the other posters said, check your box. Another way to tell, is the back of the device. If it is plain and simply says Xiaomi, then it's the China version. If it has a bunch of regulatory script under the word Xiaomi, it's the Global variant. Just remember, Xiaomi got their start making custom roms and later phones, so they have always built phones that enable unlocking the bootloader.

i've actually addressed this above.
thanks for your reply,
my concern is not really to make sure that it's a CN model phone or not.
but my question is about the A/B partition when relocking.
yes i know this phone came with CN rom as stated by seller and i can confirm it myself, first boot, all chinese, some parts of the box are in chinese, no charger in box, and the device model is M2102K1C.
if you read the steps that i did, at 1 point, i boot TWRP via fastboot and flashed mi.eu 12.5.7.0 rom, twice even.
before i reverted back to 12.5.7.0 CN rom via fastboot miflash.
now to relock, i have to be absolutely sure no trace of mi.eu rom? is it still residing in inactive slot (because of AB partition), which will brick my phone when relocking even when official CN rom active slot?
that's what i want to know.
one thing i know is, if i relock bootloader with a rom not originally made for that device (custom rom or other region rom), it'll cause a brick.
i know i'm on the CN official rom that came with the device, but what about the inactive slot? will it affect the relocking of bootloader that can cause a brick? this is what i'm not sure of
after I installed a wrong indian rom my original ROM is NE2215 10 then I upgraded to NE2213 12 and it worked fine then i upgraded to A13 then i wanted to downgrade again then i installed a wrong indian ROM then I tried to get back to NE2213 and I flashed it
but I got stuck in a boot loop now so any help ?
btw my phone isn't bricked and I can go recovery and fastboot
What happens if you recover using the built in recovery??
Wait…what? Try booting the boot file from bootloader
Did you upgrade to the android 13 beta or Indian rom A.13?

He's downgraded dude.... Not sure a boot image will help him.... This is a situation that MSM was made for tbh.
Can try the boot image, but for what ? 13 or 12? EU or Indian?
Bit of a mess.
Edit: from the OP, it would seem he's on the EU firmware. But no way to tell what firmware is currently taking up the majority of his devices system between 12 or 13
I would try recovery, but yea sure booting an image shouldn't hurt.
I mean... You said the problem is that you flashed the wrong firmware: if you can boot in recovery and Fastboot, just download and flash the right firmware

Hey,
It really depends mate, but for me if I've had a bad flash and my recovery is still intact then I'd boot to my bootloader, then recovery, then just do a full wipe from there, this pops the operating system back in there and gives you a functional OS back..plus you bypass the need to identify what OS is indeed installed meaning you aren't attempting to identify the OS and by and large making a mistake, unless you can categorically identify it, something you may not be able to do without it booting.
Few things to note, I don't know how far the last firmware change you made got to.... So this could fail, but I cannot see it making things worse, I've not a had a problem with this method before but I've not been in the exact situation you're in so there is always an inherent risk.
You could go ahead and attempt to boot the boot image from the last firmware you had in a working state and see if that works, bare in mind I'm saying boot via fastboot, do not flash, I mean boot, if it fails, just reboot and you're back to where you are now.
If that works then fantastic, you're back in business, if not then you could either attempt the recovery wipe like I said OR go down the fastboot a full firmware method.
That should also work but that would be my last thing to do, it would mean extracting a firmware image by image from payload.bin then flashing each image over.
Apparently it's possible via fastboot enhance, but (sorry I know it's not too helpful) I have not had to do this myself, I was going to but recovery wipe worked for me instead.
Hope this helps mate, if you're unsure then let us know before you commit.

try flashing the downgrade rom, above the post that says WARNING. BOOTLOOP.
Fastboot Enhace
Make sure you check the box that says allow incremental or else it won't let you extract the downgrade rom.

I'm not sure if you can flash the downgrade rom through recovery or not, but you can try the following as a last resort. I am not responsible if you end up breaking your phone and this should only be used as a guide that you need to modify yourself since this script came from a oneplus 9RT fastboot rom.
