[Xiaomi Mi 11] SpYneX_:
Hi everyone, I'm writing this post to ask for your help regarding an issue that is driving me to exhaustion. I also apologize in advance for any errors. It all started after trying to overclock the gpu with the konabless app, previously the app made me make a backup of the vendor_boot image in case of post modification problems, so next i edited the frequencies of the gpu, I applied the changes, rebooted and BOOM, a phone freezed at mi logo. So I rebooted in twrp to reflash the stock vendor_boot image, and for my great intelligence I flashed it on the boot image partition, and what did I get? A phone stuck in fastboot.

Oh well, a phone that turns on in fastboot is not a big problem you'll say, and I thought the same as i previously had a problem and solved it by reflashing the stock rom in fastboot, so I took my nice computer (actually it's a 12 year old pc that runs on carbon, but that does its job), I opened the mi flash tool, connected the phone, selected the fastboot rom, precisely the EEA 12.5.7.0 (like the one natively installed before the damage) and started the installation. 20 minutes later ... error: cannot load bla bla bla, ok ok, i seached various solutions on Google and tried every metods, i changed the directory of the mi flash, of the rom, I updated the version of mi flash, i installed both on C:/ drive, reinstalled the drivers, i edited the batch file to remove the anti rollback but nothing, it arrives at flashing the super image and after some minutes it fails the flashing. Before you ask, YES, the bootloader was unlocked. I also tried to flash the rom in twrp, but ... the phone no longer had the twrp. The only way to start it was via command (fastboot boot twrp.img), the onekey injection did not make it permanent, and connecting the phone to the pc it revealed the device, but not the internal memory, I tried to make a format data but nothing. I managed to make it permanent only once, manually flashing only the vendor_boot and boot images in one of the boot_ * slots, in that case incredibly the pc also detected the internal partition, I copied the flashable rom and ... the twrp said to restart the recovery for I don't remember what, but basically I couldn't install the rom via twrp. At that point I finally gave up and took the phone to an authorized xiaomi service center where they fixed it (bye bye 25€), I don't know how exactly, I would opt through edl mode I think, and now i have my working phone...but heeeeeey, they flashed me the 12.0.1 TW version, not the EEA... Ahhhhh come on. They also re-locked the bootloader, so... agaaaain i re-unlocked the bootloader, this time i downloaded the unofficial tool xiaomi flash tool v2, it installed every needed driver, i clicked on "my phone works and i want to mod it", this time i tried to flash the global rom 12.5.7.9 and when it arrives at flashing the super image IT FAILS (fast boot flash_all failed, exit code:1, output: flash super error), and like a nightmare the phone was stuck in fastboot again, fool once but never fool twice, this time I had previously made a twrp backup of everything except the data partition, I install it and the phone restarts perfectly, I also notice that despite the attempted flash of the rom in fastboot after restoring the twrp backup without the data partition, nothing has been deleted from the data partition. So benevolent gods of xda, how the heck should I change rom region? Thanks for your attention and I hope I haven't stressed you out any more than I already am.
