After switching back to backside for a while, I decided to come back and try the internal build.
The rom flashed, but gave in error that /data and /system failed to read or something.
They also wouldnt mount. I'm pretty sure its because I wiped them..
Other recoveries operate normally and access them without issue. Im sure im missing something obcious....
Lessee... internal rom will still flash in os2sd mode (advanced-internal or os2sd)
but won't wipe right.
Your internal partitions're fine.
And using twrp new as or newer than rom or not good results.
