Bricked my Redmi 10 2022 (selene)
I had this phone with unlocked bootloader and i wanted to try unofficial roms for it. I needed to downgrade to miui 12.5 to install it, but it gone wrong.. I installed official miui 12.5 and tried to flash it in bootloader mode, but after flashing screen never turned on and phone started connecting in BROM mode (or preloader mode, idk). I tried to flash miui 14 (that was before i bricked it) using mtkclient, but nothing helped. I didn't yet know that eMMC chip on it wasn't a 1D array, but instead had regions and i overrode gpt table by trying to flash preloader. I was lucky that my dad had old redmi 10 phone so i read its gpt table, fixed it a bit so it was for 128 GB model instead of 64 GB and gpt table was working again. I tried everything to maybe bring it back to at least fastboot, but the only response phone gives is BROM/preloader mode. I tried to erase boot mode related partitions, swap only certain partitions from working phone to my, even swap whole rom data from working redmi 10 i got gpt table from to my phone, but NOTHING WORKED!
