[HTC 10 Guides, News, & Discussion] tst1212:
I bought a US Unlocked HTC 10 from Ebay, supposedly new. I HTC S-Off and Sunshine root, and both were successful. My goal was to convert it to Verizon, but that's where things went bad. I changed the CID to VZW__001 , tried to Flash the firmware and no luck, got errors. So now I'm considering switching to ATT and would like to get the phone back to US Unlocked. I switched the CID back to BS__US001 and tried to flash "3.16.617.2_FULL-WIPE_firmware.zip" and got the below errors;

So then, if I flash TWRP and run a Wipe process, I get three partition errors.

Failed to mount '/system' (Invalid argument)

Failed to mount '/carrier' (Invalid argument)

Failed to mount '/persist' (Invalid argument)

Should I htc_fastboot erase the partitions, and try again?
