Also, I tried using a micro-B cable instead of micro-C, connected to a Linux computer, and I noticed that after the calculator reset, it appeared as HP Prime, not "SE Blank 6ULL".

My notes do say TP907, which is next to the top-right corner of the SoC, but I cannot remember if that's actually correct (it could've been TP807 if I wrote it down wrong, but I doubt it).

There is theoretically another way, which would be to short two NAND data pins together to force the SoC's ROM into recovery mode (if it can't read successfully the NAND chip, it should fallback).

If all else fails, there is the option of hooking a JTAG probe to the back of the motherboard (https://tiplanet.org/forum/viewtopic.php...27#p238167), but it's glued to the back of the case with an adhesive film. It can be separated with a plastic spatula (or carefully with a knife) and some paper sheets to stop the motherboard from gluing itself back, but unless you actually need to access the pins on the back I wouldn't recommend doing that.
