You need to flash version 14 stable to both slots
I tried flashing that version but I get Qualcomm Crash Dump when booting into recovery. But I can boot on Version 2 though. If I try fastboot flash recovery_a and fastboot flash recovery_b, it will put qualcomm crash dump. I also tried to boot into the recovery by using fastboot boot but that also didn't work. Any help here to get version 14 to work?
