[HTC 10 Questions & Answers] kimba99:
maybe the conversion from 2PS6500 -> 2PS6200 makes TWRP mess with the partition layout or is it the 64GB edition thing?!

not sure if TWRP currently accesses the partitions by-blockID or by-name ... so maybe the partition layout of my "htc_pmeuhl XC" (not PVT!) could be accessed in an incorrect way due to a different partition layout???

here the partition layout via adb su-shell: (connected to ... currently viper10 5.11 magisk-systemless edition)
