I don't have a 0x9302. So I can not test it.
I do have several other controllers that I could try e.g. 0x9341
But seriously. Why don't you buy a TTGO R32 board and do the hardware mod described by Bodmer?
I did ask what ID was reported by graphictest_kbv.
Please answer.
Incidentally, you can SLOW down the ESP32 via the IDE Tools Menu. Does this make a difference? e.g. when reading the ID.
