Help! My RED Hydrogen One is bricked… It’s boot looping / stuck in Fastboot Mode… the only thing I’ve been able to flash is TWRP (a special variant that runs on the device) I’m going to try to install a generic version of Android 8… If you have some sort of recovery img can you share it… I really really need one. Anything will help, Thank you!
by surfing on internet it seems that someone have unbricked and updated to ver 9 of android here UNBRICK RED HYDROGEN ONE WITH STOCK ROM (PIE) (EDL REPAIR+FASTBOOT FLASH) | Page 2 | XDA Forums
