Can't update my Redmi K80
I'm unable to complete HyperOS update on my CN version Redmi K80 phone. I get a notification that there is a new update, i click it and it downloads it, but after it finishes downloading the update, it tries to extract it, it stays at 0% for like 10-15 seconds and then gives the following message " Could'nt update system. Download ROM and try updating again" . I tried downloading 5 times, it downloads 7GB every times but then fails to proceed with the update. Any solution? This is a second hand phone from China, the ROM is Chinese, and the bootloader is locked.
