[HTC U12+ Questions & Answers] DaAndereAndre1:
Hello guys!

As I managed to get to this exact issue described in this thread after trying to flash Viper Beta 3 (don't know excactly where things did go wrong...),

I'm curious if we will be able to make the beloved U12+ working again...

I don't know if that changes anything regarding this issue, but what is interesting is that if i check the current slot, switch it to B, switch back to A and send the command to set A as active once again, I'm able to temporary boot into TWRP... No chance if I don't do the slot switches before... But currently I'm know sure if that changes anything as I tried to flash system.img afterwards, but still stuck in fastboot...

I think RUU is also not an option as I'm not able to determine which version I would need as this is my output from getvar... Does that tell me that the partitions are completly srewed up? Any ideas based on getting in TWRP?

EDIT: I would also like to try if I can get into Download again when flashing hosd.img but the spreasheet in the factory image collection thread is offline and I can't find the img anywhere else on the web...
