Technology without spirituality makes our world so ugly

HAVE FUN

EXTRACT 2 NAND HVJ6MFG AND INSTALL ON ALCOR
AND DO JUMPER MOD

PART 3
TRY USE 3D SUPPORT CONTROLER FOR NAND
I FOUND AU6998SN-GTC
IN FEW DAY I WRITE RESULT PLASE WAIT...

PART 2=>NAND NAND IS DOWNRADED TOSHIBA 3D TLC
HV=LOW PE PROGRAM ERAE TIME AND BAD BLOCK TOO MANY

FOR 64GB?? LOW COST PCB? IN USB3?
This is a betrayal
EVEN IS917 HAVE 3.3 VOLT COIL

I CHECK 5 VOLT FUSE AND BETWEEN GND AND VCC MULTIMETER SHOW 640
SO 5VOLT FINE >The problem is not the customer SYSTEM

3.3 VOLT IS GONE
PROBLEM IS PCB Low cost Stupid design
