I was using my phone normally yesterday (Saturday) 12/06, I left it charging and when I looked at it again, it was restarting non-stop. It's a Redmi Note 8, I held the power button, but it wouldn't turn on, it just went back to the bootloader screen, I didn't try to format it as I'm trying to recover my files. So I thought about unlocking the bootloader to have access to my files, I used Mi Unlock Tool, but it doesn't work because it asks me to add my account to the device (It was already added before this happened). I still have access to my account phone number, and email. But I couldn't unlock by this fastboot method, so I tried using the "fastboot oem unlock" command, which didn't work either, it showed these two messages.
'Fastboot boot command is not available in locked device'
FAILED (remote: 'Token Verify Failed, Reboot the device')
fastboot: error: Command failed
The versions of MiFlash Unlock I used were
"miflash_unlock-en-5.5.224.55" and "miflash_unlock-en-5.5.224.24".
The device is not recognized by the "Mi PC Suite".
The device still appears in fastboot devices, but not in adb devices
bump
When unlocking phone's bootloader automatically all user-data get lost.
Hint: Add Redmi Note 8 to this thread's title thus mainly owners of such phone get addressed.

Ok!
When using "MiFlash Pro", I managed to reach 100% (?), but the device resets, gets stuck in the MIUI screen for 2 minutes and then resets again to the bootloader screen. I was flashing the same ROM i was using, the "V12.0.4.0.QCOMIXM".

Hello,
I've ****ed up my op nord.
The phone was running lineage 17.1 verison 29-7, I did a lock of the bootloader.
Now it's locked with the message 'your device is corrupt. It can't be trusted and will not boot.'
When I try to boot as with the power/volume up combo it show the 'Qualcomm CrashDumpMode screen
I tried to unbrick it using the EDL method, but the phone doesn't boot in EDL mode.
I've followed the instructions as written on https://www.getdroidtips.com/unbrick-oneplus-nord/.
However, the phone doesn't boot in EDL mode.
Any suggestions how to proceed?
Hi,
I facing same issue with OnePlus 9R device. I found on internet that EDL can be triggered from hardware as well. So there’s still a hope.
In case if you have resolved this issue, please let me know
i used to be able to have custom rom on this phone but i tried updating the custom rom but it put the phone in a boot loop. then i used msm download tool which got me on stock. then stock updated on its own overnight and now i cant enter edl mode. idk what to do. any help is appreciated
Hi all
I had just finished installed Lineage and twrp succesfully to setup this phone, but I then discovered that the unlocked bootleader was preventing me to install Netflix.
I then tried to re-lock it via "fastboot oem lock" which apparently worked, but the side effect was that my main system is now not booting at all.
And when I've then tried to unlocking it again, it just fails, so I'm currently closed out.
Right now I can only access fastboot mode.
Any idea if this can be saved?
thank you
It can be saved but you need to use EDL mode (Emergency Download Mode). This mode is locked by Xiaomi and you Need an authorized account to use It.
You have 2 options:
- Pay a man that have an authorized account and can flash the stock rom from EDL.
- Go to an authorized Xiaomi center.
Thank you. Luckily that was not the right answer.
I've managed to put the phone in EDL mode via hardware, after opening it up.
After bypassing also the lack of helo message error, I've finally manage to flash with Xiaomi Flash tool and regained access to it.
Hello everybody,
i'm not new in custom roms, but i have a problem, i can't solve by myself:
I flashed an unlocked Mi5 to linageos 19.1 without problems.
I had the bad idea to relock the bootloader due to security reasons (fastboot oem lock).
Now the device is not booting anymore, i can just see the Mi-Logo flashing very shortly.
I can access fastboot, but can't boot into recovery.
I tried to unlock the device again, but the Mi Unlocker fails and prompts me to go to the developer options in Miui, which is clearly impossible.
Any chance to proceed from fastboot (fastboot oem unlock does not work...) ?
Thanks, Jan
congrats, you succesfully hard bricked your phone. please take it for a walk to the xiaomi service and pay for gettting it fixed. who told you it is a good idea to relock the bootloader with a custom rom installed ?

actually, i remember some banking apps complained about the locked bootloader. I thought i can lock/unlock it in fastboot mode, but looks like i was wrong.
I will give the MiFlash Tool a chance, but i have not much hope...
@Fytdyh: do you think, Xiaomi Service can fix it ?

Make sure if your bootloader is really locked or not using fastboot command
fastboot oem device-info
OR,
fastboot getvar unlocked
If it's not locked, you can simply flash your stock rom using flash tool available for mi. Before downloading a rom from internet, take note of your device info using fastboot command ,
fastboot getvar all
And if bootloader is really locked, you have to flash stock rom from EDL mode. You may have to remove back cover to turn on EDL mode. Your device has snapdragon chipset (Plus point). Watch tutorials about xiaomi edl rom flash - snapdragon. You can go to service centre. If they tell you that you have to replace motherboard, don't be agree. Tell them to flash rom using EDL mode.

looks like i am getting closer... located the two EDL points to short during PC connection, installed the Qualcomm serial driver. For a second i see the device appearing as COM6 but then it disappears again and is not availiable anymore.
Any hints ?
Thanks again, Jan

Try this to solve the issue.
If it doesn’t help, read this to boot properly into edl

Flash stock recovery for your device via fastboot, then you should be able to boot into recovery or flash a stock system.img or your full stock firmware for your device, then unlock the bootloader(fastboot oem unlock) then flash TWRP and LineageOS again.

But he mentioned, bootloader fails to unlock. Actually it's hard brick(Even though he can boot into fastboot,the bootloader is locked. So nothing to do with fastboot).Without unlocked bootloader, flashing something from fastboot will hard brick his device completely (Will not be able to boot into fastboot). Or flashing will be denied

OK, next level reached. The phone is connected to the com-port and the correct driver is displayed.
The whole procedure is a bit unstable, i need to connect the phone several times, to get a stable EDL mode.
The Xiaomi Flasher recognizes the phone, but flashing does not succeed. Sometimes it's not able to receive a kind of Hello message, sometimes it displays "object reference not set to an instance of an object".
I also downloaded the QPST flasher, but have no plan, how to use it.
I'll keep on trying!
Thanks to all, who helped me to reach this point!

I found something new by watching this video. Maybe you don't understand hindi(India is our relative country, so I do).
Lemme explain,
This guy's xiaomi k20 pro phone hard bricked with a locked bootloader. He tried a lot to repair it(by deep flash or something idk). But everything failed. At last he came to this step of EDL mode. But xiaomi Edl mode flash requires an "AUTHORIZED MI ACCOUNT" . Xiaomi people pay to get authorized account license that normal users don't have. So the guy contacted with them on a telegram page called "Mod Edit: Name Removed" . They told him that they will repair his phone via teamviewer. All he had to do is pay some $ & connect phone in edl mode. Rest of the things were done by them. And his phone repaired successfully! (Watch the video from 4:00)
So In his video, he is telling to go to that page & contact with "Mod Edit: Name Removed" there. They take 20-25$ (depends on device). If you tell them you're from Mod Edit: Name Removed's video, they will give some discount

Yeah, I jumped the gun and posted before seeing all the replies in the thread describing their whole scenario, should've known better.
They obviously need a hardware approach, i.e. JTAG/RIFF/Octoplus or replace motherboard.

Thanks for research!
Meanwhile, i stopped using Windows due to all the caveats and switched to reliable Debian Linux on a different machine.
Again it takes 10 attempts to get into EDL Mode.
I used qdl (Qualcomm downloader for Linux) with all the firehose, raw and patch .xmls
Code:
sudo ./qdl --debug --storage ufs --include . prog_ufs_firehose_8996_ddr.elf partition.xml rawprogram0.xml rawprogram1.xml rawprogram2.xml rawprogram3.xml rawprogram4.xml rawprogram5.xml patch0.xml patch1.xml patch2.xml patch3.xml patch4.xml patch5.xml
Output looked like some stuff was written, at the end i receive:
Code:
qdl: failed to write: Connection timed out
However, the phone is now dead as can be without fastboot working any more.
Maybe i'll give it another try, or get a used Mainboard...
Best regards, Jan

That's expensive. Anyway, it will be better if you don’t waste time on this. Just go for 3rd party help(From that official telegram channel or service centre). That will cost less

Thanks Tawsif for the good hints and links.
I don't really depend on the phone, so i will keep trying.
It's not wasted time, it's mainly learning new stuff and improving skills.
I believe, i'm not too far away and if it works, it's the best satisfaction.
If not, i bricked an old Mi 5.
All the best,
Jan
