you have a hardware problem look a nand chip pin? is welding is ok?

before do anything First make sure in chipeasy see the nand flash id
Example

AD DE 94 Eb=Hynix MLC 16K

i always type Easy in english to understand all people

i am iranian and my language is Persian

i put the picture and explane all information step by step

but more than 100 email to me about sm3257enba!!!

IF YOUR 3257ENBA NAND IS MLC CLOSE SB8 And use Star_SM3257ENBA_N0228


just that

no card mode or change isp file

OK LEts To TEST

I DO Seeting You Just Select 03TLC.ini for tlc or 03MLc.ini Good luck

look other Files

File 146 Is MP.ini

Look that

Run Resorce Tuner And Open the Phison225103.exe

in EXterApp(this Mean Extrnal Applocation) have same file

I Save All And open one by one by note pad And Extract it

1-Download Sp Downloader From Silicon-power.com-Support -Download -Recovery

2-Spdownloader Detect 13fe 5200 and Download the Phison225103.exe

3-Download the Resource Tuner for Extract the Exe File

fc alwayes for downgraed nand

in fc mptool ecc=0 capacity optimeze

password is 123456

SB8= USED IN MLC

IN SANDISK NAND WE MUST 2 OR MORE TIME ERASE ALL +55AA

SANDISK NAND TABLE IS VERY BAD AND VERY EASY TO LOSE MBR AND CAPACITY

I ALWAYES SAY I HATE SANDISK

FOR 19NM TLC =ECC 48
FOR 24 OR 19NM MLC ECC 30

FOR (5D2F)MLC (TC58NVG5D2FTA10,TH58NVG6D2FTA20) 15 BIT ECC

FOR SUMSONG TOGGLE TLC 48 BIT ECC

FOR L63 (I29F32G08AMD2,MT29F32G08CFAAA) 12 BIT ECC

NOTE:

ALWAYES IN TLC MORE THAN MLC USED ECC (BECUASE TLC DATA SAVED IN TRIPLE CELOL)

INSTALL OTHER SANDISK ON PHISON 2267

IN UP TOOL CLEAN ALL

CAPACITY OPTIMIZE
FULL SCAN ONLY

TEST YOUR MEMORY SAFE OR NOT?

هیتر کشی بد انجام دادی اثرات گرما زیاد رو شاسی بدنه دیده میشه
نند ساندیسک به شدت به حرارت حساسه و زود خراب میشه

مموری باقی مونده رو رو فیزون 2267 امتحان کن
اگه سالم بود یه صفحه جدید واسه مشکلت ایجاد کن قدم به قدم کمک میکنمت

FOR 1 OR 2 TIME ERASE ALL BLOCK

AFTER ERASE REPLUG AGAIN AND DO MP

Capacity optimize
