PS3111-SSD fix hardware problem



to day we have PNY 120GB .NOT WORKING PROBLEM?

AND I TRY EXPLANE ANYTHING



It does not show any reaction

WHAT VOLTAGE MUST HAVE?
NORMALY ONE DC TO DC CONVERTOR =5=>3.3 VOLT FOR NAND FLASH AND CONTROLLER
OTHER 1.8VOLT FOR VCCQ

ALL INTEL MICRON 3D NAND(L06B NAND USE 1.8VOLT)
SOME OTHER NAND LIKE TS(TOSHIBA SANDISK )BICS FLASH (SOME TIME 3.3VOLT VCC 1.8 VCCQ)
BUT SOME TIME JUST 1.8VOLT

ITS FUNNY AFTER REMOVE COVER ISEE (256GB) LABEL


OK I SHOW DC TO DC CONVERTOR



ALL VOLTAGE IS NORMAL
DC TO DC CONVERTOR IC RANGE CAN CHANGE BY 2 RISISTOR .I DO NOT PERSONALY SAY YOU CHANGE IT
JUST SAY TO YOU UNDRSTAND FULLY
YOU CAN READ RISISTOR OHM,AND KNOW VOLTAGE
EXAMPLE



SO IN THE END .ALL VOLTAGE IS PRESENT
LETS DO ROM CODE JUMPER MODE
MAY BE FIRMWARE IS CHOKED
INSTALL USB TO SATA +SSD AND CONNECT JUMPER I MARKED IN BLACK COLOR ON THE PCB PICTURE
AND OPEN MP TOOL ,TO SEE ALL NAND IS PRESENT OR NOT


AFTER CONNECT OPEN PS3111-SSD-MPTOOL (I UPLOAD IT TO FLASHBOOT.RU 1YEAR AGO )
CLICK REFRESH .DUBLE CLICK ON ICON BLUE


SO WE ARE BAD SOLDER PROBLEN
CHANAL 0 2CE IS NOT CONNECTED TO PCB
98 3C 98 B3 76 E3 = 98 IS TOSHIBA — 3C IS 32GB- 98 IS TLC -B3 IS 3D- 76 ???-E3 IS GEN 4

WE USE HOT GUN+FLEX TO RESOLD CHIP


I USE GORDAK 852. MAX TEMP AND GOOD FLEX JUST NAND CHIP
AFTER 10 MIN COOL DOWN INSTALL
ON PC AND WORK AGAIN
WE HAVE DRIVE AND ALL FILES DONT NEED TO REFIRMWARE
WHY NOT FIRMWARE (BECAUSE ALL NAND CAPACITY IS 256 (983C98B3 *8=256GB)
SO HALF ISS BAD BLOCK
AND RISKY
SSD STOP WORKING BECAUSE OF NAND SOLDRING
ALWAYES DO REMEMBER THIS .LGA,BGA CHIP 50% IN FAIL CHECK THE NAND ID

OK TEST TIME
