I also tried these drivers !!! I tried to uninstall all the drivers and redo the procedure! As soon as I connect the phone, it sees it as an MTP device and gives me an error. I don't know what to do anymore! I doubt that it is a hardware problem!
I am in the same situation. I have to add that I have installed TPRW and I know that it's not compatible with A12. Have I to remove it (installing before the stock recovery) or I can directly install the last update 13.02, with the relative bat file, without data formating?Now my phone is run on Miui 12 stable. Should I execute "windows_fastboot_update_rom.bat" if I update from Miui 12 stable to Miui 13 stable? or clean install?
