SM2263XT PROBLEM

HI AGAIN .WE HAVE SSD
NO RESPONSE .ALL LED IS OFF

BUT WE HAVE 3.3 VOLT FOR NAND VCC ,1.8 VOLT FOR VCCQ. NAND IS 29F32BALCTH TLC ORGINAL BRAND INTEL
128GB

AFTER ALL VLTAGE FINE .INSTALL SSD ON USB BRIGE .CLOSE ROM CODE JUMPER


AFTER JUMP THE ROM CODE MODE ,LED IS BLINKING SO .OPEN THE MPTOOL TO SEE IS ALL FLASH IS FINE OR NOT

DOWNLOAD 2253XT VERSION IM B16 OPEN IT
CLICK INFORMATION ICON




SO REBALL THAT



I TRY 2 TIME REBALL CHIP BUT STILL CH2 IS NOT DETECTED
SO I TOOK CH0 NAND OUT AND INSTALL TO CH2 TO KNOW
PROBLEM IS PCB? CPU LINE? OR MAY BE NAND CHIP IS DEAD?

AFTER INSTALL OTHER NAND .I KNOW NAND IS DEAD

I CHECK ALL DATA IO,VCC,VCCQ .BUT WE CANT FIX IT
ALSO WE CANT SUPPORT 3 CHANNEL ON B16 (ONLY 48GB B0KB SUPPORT 3CE)
SO I JUST INSTALL 2 NAND .AND FIRMWARE IT TO 64GB
