Xiaomi Mi8 Bricked after locking bootloader - Android Q&A, Help & Troubleshooting

Hello. I have a problem. I have Xiaomi Mi8, which was sent back on a warranty, because it just didn't powered on one day. It was sent from PL to China, they sent it back after a month and from this time I had some issues. The phone came back with unlocked bootloader. I couldn't use Google Pay to use contactless payment, couldn't install Netflix for example, and other general problems caused by unlocked bootloader appeared.
Today I wanted to change that, so I entered fastboot mode, connected phone to PC, and entered "fastboot oem lock". It said OKAY, finished, but then phone was stuck in a bootloop.
In recovery, it says that "This MIUI version can't be installed on this device". Wiping data doesn't help.
I wanted to re-flash it with Global ROM, but Mi Flash says "Error: FAILED (remote: Erase is not allowed in Lock State)"
I wanted to unlock it using Mi-Unlock but this fails also. It ends with "Current account is not bound to this device. Add your account and device in MIUI's Settings Developer options Mi Unlock status" message.
I cannot enter settings because phone will not boot up. I read about authenticating with account_auth.exe on c mi com/thread-2173190-1-0.html (remove spaces, sorry but I cannot post links yet). I logged in, but then instead of "Unauthorized Xiaomi account" I have "Request failed" message and I cannot click "Apply Bind".
I'm running out of ideas. Phone will not boot, it can't be flashed, what else can I do other than replacing main board? Please help.

I had the same problem with Redmi Note 7 pro I have changed from china version to India version but I had some security issues with some app as the Bootloader was open since I flashed India version I did as you did from cmd I loced the Bootloader so the MIUI was blocked and phone was bricked I had to use boxes software then go back to china version again then setup new mi account with new E mail and different SIM then I was able to flash new global indian version of MIUI 12.5 but unfortunately I lost my IMEI 1 but lucklly had saved my Data on Google account ,so you should use boxes software to use your phone again!

Failed bootloader unlock. Phone is now locked to another mi account. Need help

Hi there. I was following a guide on how to unlock the bootloader for the xiaomi redmi note 3 pro and it failed on the last step as i entered fastboot oem-unlock go
now when i rebooted the phone, it started up a new setup process and in the end it says my phone is locked to another mi account and that i cannot access it without the password. according to the miui forums there is a way to bypass this, but when i start extracting the .tgz file, i dont get the same files as listed and when i try to flash it again using miflash, it says files missing and i cannot proceed.
How do i get this issue fixed up so that i can get my phone back to at least function without all headache? I have flashed and unlocked a nexus device before but it never gave me such issues. Thanks in advance
(unfortunately it seems that i cannot post outside links as its a new account)
i managed to unbrick my phone, but going through the unlock process, after i enter fastboot oem unlock-go it would give me the result of Failed: token verification failed. how should i proceed

Couldn't check Finde device status???????

Hi everyone.
1 - After my xiaomi redmi 3 Note Pro was in bootloop I flashed it with MIUI Global 8.1/ Stable 8.1.1.0
2 - At the first boot, when I had to sign in to my Mi Account, the phone started saying "Checking Find device status...", without letting me even try to sign in.
3 - So i tried to flash the phone again but it doesn't work now: with every image version and every MiFlash version I try in MiFlash says [error:"Flash tz error"]. I've seen that this probably happens because my bootloader is still locked.
4 - So I tried to unlock it with the standard procedure with MiFlashUnlock, and after all the procedure I received the message, but when I try to unlock it says: "Couldn't verify device, current account is different from the account info on the device". So I've seen that this is because I can't login into my account in the phone (see section 2).
5 - I noticed that I'm able to access the apps and the settings of the phone even if I'm in the mi account login screen (see section 2) holding the center button and going to google now and searching for settings or app names. I tried from the settings to reset the phone but it doesn't allow me since I'm not logged, I also tried to update the phone with the update app, but it doesn't let me.
Pls help
Got same issue with my RN3Pro Kate, is there any solution?

Xiaomi different versions LOL + "current account is not bound to this device!' error

Xiaomi different versions LOL + "current account is not bound to this device!' error
I finally found out there are looooooooooads of Redmi types, unbelievable!
Maybe Xiaomi should minimize their offer, I thought I had a Redmi Note 3, but I finally found out it's a
Xiaomi Redmi 3 IDO (3A) Snapdragon LOL
I ordered one for my daughter, and now I see it's actually a Redmi Note 3 (bit more expensive and different at the back).
==> So i'm busy checking out how to flash, I got the official sms to unlock the locked bootloader and the first part goes to 100%, but theb I have another error : "Current account is not bound to this device!"
I'll guess some more errors will follow seen this long & difficult process
I dowloaded the latest miui_MI6Global_7.8.10_024aaf1afd_7.1 of this week, but now I need to get rid of that error & locked bootloader.
Do I need to flash an old beta rom first or something to get rid if this error message ?
Nice to see a fellow Belgian here
I am a bit confused. You are trying to flash your Redmi 3 (ido)?
Because the ROM you say you've downloaded is one for Xiaomi Mi 6...
Could you provide some information (screenshot of your 'about phone' with the current installed MIUI ROM etc?)
When I unlocked my ido's bootloader last year, I flashed the Chinese developer ROM using MiFlash, coming from a fake vendor ROM via EDL mode. Then in China dev ROM I unlocked the bootloader using MiUnlock.
After that I flashed TWRP (flash lazyscript before booting into the system or change to custom ROM immediatly because dm-verity is a b****).
I believe in recent ROMs, EDL mode was blocked by Xiaomi.
About the error: make sure you log in to the unlock tool with the same account as you are logged in to on your phone (the account with unlock permission). Then go to "developer options - Mi Unlock status" and make sure your account has been bound to the device there.
USB-debugging should be enabled, as well as OEM-unlock.
I do not know when you received the unlock code, but it is possible you'll have to wait a week or so. A lot of people have found that it suddenly works after a few days of waiting.
If you cannot switch to a developer ROM due to locked EDL mode, you should be able to flash your ido with locked bootloader using xiaomitool. http://en.miui.com/thread-835254-1-1.html
With this tool you can switch between MIUI ROMs on a locked bootloader.
I don't see any reason on why you download Mi 6 (sagit) recovery ROM instead of Redmi 3 (or Redmi Note 3 if it's what you're talking about) one. For "Current account is not bound to this device" error, wait for at least a week after you bind your Mi account with your phone before unlocking.
Good luck.
Sent from my Redmi 3 using XDA Labs
Haha greetz to Belgium too Yes I was a long time since I checked the latest roms / Xiaomi phone versions
Now I have a rooted stable MIU9 V9.2.2.0 Laicnek and looking for the best battery saving Kernell, hope I can flash this simply with TWRP as everything is installed allready
What do I need to choose again in the options to flash a Kernell only ?
Otherwise the Lineos 15 with the latest Oreo (if there is an official version 15 already, as I see only a beta 2)

Can't unlock bootloader || flash new ROM...

Hello.
I recently got my new Redmi Note 5 3/32GB Global version. Simply, I don't like MIUI's 10 performance, so I want to use custom ROM. I logged to my MI Account, downloaded Mi Unlock (v3 and v2).
v3 - account application area query failed
v2 - it counts to 50% then stop with message "Device unlocked no need to repeat unlock"
Mi Flash - does not see my device, same as fastboot. USB Debugging enabled, currently running on MIUI 10.0.2.0.
+ I tried to create new account, ends up with some error message in chinese.
How to unlock that tarded bootloader? Thanks for your time...
Did you follow every step? Checked "OEM Unlock" in settings, linked account to device?

By the message that you received it looks that your device was shipped unlocked.
What do you type in fastboot mode to say fastboot doesn´t recognice it? provide some screenshot.
Did you check in developer options to verify if is already unlocked?

Nope, it's kinda common problem.
Finally, after 3 hours I got message which says, I have to wait 357 more hours to unlock bootloader. Factory reset + No SIM helped

Help on unlocking bootloader, RN4 Snapdragon

Hi there, so recently I bought a Redmi Note 4x from a Chinese seller in an online shopping store on our country.
I opened it up to see MIUI 8 but all in Chinese, though I managed to get it to English. Got it upgraded (OTA) to MIUI 9 and 10 global stable.
When I try to unlock the bootloader (new method), I always get error 20091 on Mi Unlock Status, even though my account has been binded to my phone.
I even tried Mi Unlock tool, but it returns an error after hitting 99% *see attachment (63)*.
I'm really puzzled by this since I just found out the phone wasn't an official global version. (Thru xiaomi product verification) so I decided to try and do something about it. I even tried shifting from Global stable to Global developer, still no luck, the same errors appear on Mi Unlock status and Mi Unlock app.
I even went as far as disassembling the phone and forcing it into EDL test point mode, and then flashing global developer fastboot rom via MiFlash as stated on this guide https://c.mi.com/thread-1479882-1-0.html but still I cant unlock my bootloader and the same problems appear.
UPDATE: I also tried using an unofficial unlock tool (which made my shift from global stable to global dev possible) but the xiaomi unlock server returns me error 20038 *see attachment (64)*
I really need some help since I want to unlock its bootloader and mod this phone.
Ps. btw, I even tried using different Mi Unlock tool version, but still got the same set of problems.
That link you shared is very good. I'm really surprised that it didn't work for you.

I'm even surprised it didnt work....maybe it has something to do with my hardware itself. I do think my hardware isnt made by xiaomi, since when I opened it up, only thing I saw (that i think made by xiaomi) is the battery....does it ring any bells?
Did you solve the problem? I have a Redmi Note 8 and the xiaomi server is responding with the same code:/

Error 20091 on Mi Unlock Status was a cause of the situation that your phone was binded to another Mi Account (probably the first owner of your phone if you bought it on the cheap). This altogether explains why I have that weird chinese error with something like a Mi Account ID in the error message in Mi Unlock. Error 20038 is also the same problem in the case of the XiaoMi Unlock Tool unfortunately.
The only way to resolve this would be to ask the previous owner of the phone to unbind the phone from his/her Mi Account and then trying to bind again, at least that's what I read on Mi Community Forums (Reference: https://in.c.mi.com/thread-1731805-1-0.html)
I also have error 20091 on my phone now.... trying to unlock the bootloader.
Really hoping to see ways to solve it.
Hello. I have a Redmi Note 4 Snapdragon 64 GB which I bought used and the last user didn't log out before doing a fabric restoration and I cannot unlock the bootloader and I get an Error 20038 in XiaoMiTool-V9.11.10 (Error 20091 on Mi Unlock).
I have downloaded mido_global_images_8.12.20_20181220.0000.00_7.0_global_3947ba5143.tgz (mido_developer_fastboot), modded rawprogram0.xml, added persist.img, entered in EDL mode (with testpoint) and flashed and when starts for the first time i get a message that says "This device is locked" and "Activate this device" but I have not the original account used to bind it.
Then, now I am in a worst scenario because I didn't get to UBL and I cannot use it with MIUI. Now it is a bricked device.
Any idea of how I can get out of this situation?
Thank you very much

I think the best course of action here is to ask the person whom you bought the phone from for help. If you are from Philippines and bought RN4X from Lazada on some cheap deals, then you've got a big problem returning it nor getting help from the seller.

The person who sold me the mobile says that he doesn't know who created this MI account and then is not possible to do the unlock in the proper way. I have a mobile phone that has a key to protect it but I have not the key and the person who sold me neither.
What about this? https://romprovider.com/bypass-mi-account/
