Question Bricked after writing wrong boot.img

[Connor.-]

Phone: Redmi Note 11 Pro (IMEI search shows model number 21091116C sticker that came with phone shows model number 21091116SG not sure if this matters)

I have accidently patched and written the wrong boot.img to my phone after poorly attempting to setup Magisk to get google pay working on this phone
Am now stuck with the phone either booting to recovery window or I Can enter fastboot

Device bootloader is locked and i do not have a Xiaomi account linked to phone, trying to flash what i believe is ROM using MiFlash tools but fails since bootloader is locked, attempted to unlock using mediatek unlocker tools and cant manage to get this to work either

Feels like there's nothing i have not tried at this point have 20 chrome tabs open, downloaded so many different ROMs and followed heaps of different methods without any success


Edit: Account had not been linked to phone yet

Apologies if this is not posted in the correct format/section believe its right from the rules
Any help would be really apprechiated

I would think MiFlash should still work on a locked BL from EDL. What specific error do you get on MIFlash?

@orangekid thanks for the reply
Tested with multiple Global and CN roms "error:FAILED (remote: not allowed in locked state)

Are you in fastboot or EDL?

 

[seedlord]

just reflash the original unpatched boot.img in fastboot.
I have currently the problem that im stuck in poco boot logo, when I flash patched-boot.img. reflashing unpatched boot.img makes it boot again.

I tried flashing heaps of different stock ROM boot.img's but must not be able to find the original not sure, believe its a CN phone that had a Global ROM installed when i brought it but could be wrong

Ok you might need to get the phone in EDL mode. If you cannot do it thru fastboot (I think newer phones might not be able to) you might have to remove the back cover and use tweezers to do it thru test point (google or youtube test point EDL for your phone).

Then once in true EDL you can try flashing again with the tool. If you still cannot due to no authorization or locked BL or whatever, you might need to extract the stock image and use a patched firehose file to trick MIFlash tool.

I can try to look but it looks like these guys have a collection as well over here:

[No auth collection] Xiaomi No Auth Firehose Files for Qualcomm based phones.

What is this file? As we all know that Xiaomi has blocked offline flashing with authentication to flash their device. This files will ultimately help you to fix the Mi Account Authorization issue and hence unbrick your Xiaomi device via EDL mode...

I know this is a lot but my thing is in the future if you are going to modify your phone like kernel patching or anything of the sort you need to unlock your BL first. Just trying to point you in any direction that can resurrect your device.

Believe me I have been in weird situations, such as last year when I somehow flashed a bad file on my OnePlus 9 and the ONLY solution was to literally flash an Indian OnePlus 9 Pro (different device, different region) ROM on my phone from EDL, so my point is there's almost always something you can do unless you want to say screw it and send it in for repair.

I would remove the back of the phone and leave it off, because whatever you're going to do might require test point EDL until you actually get something to flash and boot. At this point I guess it can't really get any worse.

Thanks for this, i believe its a Mediatek processor not qualcomm unfortunately but EDL pins dont look too hard to access was suprised to see how easy it is to remove the glass back. I'm in talk with the store i purchased it from at the moment so will see how this goes before falling back to pulling the phone apart (only recieved it last Friday )

Realistaclly i am happy with MIUI it works fine for me only intention was to bypass safetynet with magisk so i can use it for contact payments everything else I had already setup just how i like it

Also I would try this maybe?

Tou should never try to flash anything on a phone with lovked bootloader. Even if you had patched the correct boot.img you would have ended with a brick because your bootloader is locked.
