Hello

Hope someone can help I cannot find a definitive answer hopefully in layman's terms for this problem.

Redmi Note 8 Pro Bergonia 6gb ram 128gb storage Miui 12 Global


Tried CFW 2020 Anti-Brick Corvus ....., Afterwards Phone booted then went completely dead apart from power light when connected to usb

Came accross SP Flash Tool this did help, phone now boots, all seems ok apart from when in fastboot when connecting usb to PC/laptop (tried several cables with a PC and laptop using USB 2.0 all worked prior to trying CFW) all with same result phone stays in fasboot for approx 20 seconds then reboots. Don't know if this is relevant, if I put the phone into fastboot and do not connect to usb, fastboot remains on. Is there anyway I can install twrp and root, or am I stuffed?

Thanks
Smokes

1/Try flash with Miflashtool
2/Try unbrick hardbrick method. You can find on many: Youtube, Telegram, Github, XDA,... Keep phone in EDL mode by bypass and flash by Sp flash tool.
