Flash first then relock bootloader after... you can use MiFlash Tool on PC and choose "Clean flash and lock Bootloader" option.

Totally Bricked?

I Have an Huawei P10 lite with Elemental EMUI 8.0 rom...TWRP Recovery. my Phone rebooted by itself. Now i cant boot the os and recovery...no erecovery ..and Fastboot says Phone locked and FRP lock. Is my Phone totally fkd now or can i unbrick it?
Yep. It's almost totally fkd
You can unbrick it by DC-Unlocker + HCU Client with their support, but the whole service will cost you a lot of money!

Heating issues on my MI note 2

Hi Guys,
I'm having overheating issues on my MI Note 2. Does someone experience this too?
It depends on the ROM... What ROM are you using?
I am experiencing it in custom ROMs but not in MIUI.

Factory reset can be the answer here. This or fastbooting using MiFlash the latest global rom.

Help me find a suitable twrp version for global mi 9t

Hey guys Hope your all good
I have bought a new mi 9t the global one( MIUI Global 10.3.11) (PFJMIXM) and I am not sure right now which version is suitable. I have already read those multiple threads about the twrp
https://forum.xda-developers.com/mi-9t/how-to/twrp-versions-xiaomi-mi-9t-t3955946/page7
, but still not sure which one is suitable.(knowing that I know how to unlock the bootloader)
Plus I need a way to get back to the original MIUI if anything bad happens such as soft bricking the device.
Any way thanks in advance for your help.:good:
though I'd suggest you the 4pda twrp since probably most of the users use it, one user reported an issue with restoring backups as you're mentioning it in your question. but you can use fastboot or miflash tool to return to your original factory rom whenever you desire that.

Hello
Sorry for my English, I have the same mi 9t the global one (MIUI Global 10.3.11) (PFJMIXM) and twrp from 4PDA and Magisk. everything works great, no problems. Installation is very easy, there is a manual in the zip file from 4PDA, one click and it installs itself I recommend

Yes this is the one go ahead yarayess ?
You need to unlock the bootloader before attempting to flash twrp. Did you do that?

After flashing any other rom can i get back to stock miui 10.3.11 by restoring the twrp backup?
Will it not cause any bootlooping or ARB ISSUE?

Bricked device need help

So my mi 9t is not bricked, I was running the latest EU version of miui 11 when I tried to lock the bootloader. I now have the error your system has been destroyed? But due to antiroll back protection I can't flash any of the current .tar files available for miflash tools. Is there anyway around this or will I have to wait till a miui 11 version of the flash tool images are released? Any help would be greatly appreciated!

If you have an unlock boot loader just downloaded the fast boot ROM from here https://mifirm.net/model/davinci_eea.ttt
And flash it with mi flash tool, I have updated and downgraded multiple times and I haven't encountered any problems.
And when flashing check the flash clean all at the bottom right of the program if yout don't want to lock your bootloader.
if i do not want to unlock?
