why team group used 4channel controller for 2GB .i cant undrstand
and pcb is un un usabled
becuase just emmc and dont have a tsop 48 pin
so i extract the controler from PCB

ok this pcb is good
in last picture from flash extractor used 2233 and t58nvg8d2ela20 *2 (used pcb for 64GB )

so lets start…

extract old tdk for used flash board

2251-38 64 pin is so difficult to soldring
controller pin is so small

ok do mpall and frimware

mpal 3.63+fw 2.06.10 (some people write firmware as FW38FF01V30610M.BIN but real is FW38FF01V20610M.BIN
ok time to test


in tera copy up to 22 mb
i test in win xp 32bit

ok in final
we undrstand crystal controler pcb «2232-2233-2238» is same and we can use 1channel «2237-2239»

free crystal same model is «2260-2250-2261-2267-2268»

— in alcor all version pcb is mach
example you can change au6986 by au6998sn
you dont need «n»version install crystal
— in ite also 1165-1167-1167b-1169-1176 is same
— in smi like 2 model

crystal need (3255-3254-325ac-- is same)

free crystall model (3257-3257en-enba -enlt is same

good luck…
