in cob flash

Chip on board

you must connect gnd to boot rom code mode


ok you can see the pin out

you must connect for 4 second to gnd to change vid to

VID = BA57 PID = 1001

if do not the rom code mode mptool cant detect flash
but in this nand i can firmware it by

98 DE 98 92 72 D7 ---1.1.53 ok! 19nm tlc toggle
98 3A A8 92 76 D7 1.1.53 ok 19nm tlc die size 16gb

and >=19 nm MLC like 98 DE 94 93 76 D7 1.2.10 ok

but in large capacity phison alwayes use the 98 3a a8 92 76 50

in last

shame of toshiba

in years toshiba use a19 tlc in SSD !!!!??

ok lets to test

this is mp.ini

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…
ok time to test
ok do mpall and frimware

mpal 3.63+fw 2.06.10 (some people write firmware as FW38FF01V30610M.BIN but real is FW38FF01V20610M.BIN
2251-38 64 pin is so difficult to soldring
controller pin is so small
i remove the Between connection with wire

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
i read the pcb number and search in internet
for undrstand is pcb support dual channel or interleaved?
finaly found in flash extractor
I found this pcb (old tdk 4gb 2251-32 and 2 hynix mlc 4k )

now i have a 2251-38 and 2(th58nvg6d2..)

i loking for Good Flash Board

in phison site say 2251-38,2251-33,2251-32 is pin to pin Compatible
also i have team group flash 2gb phison 2251-38 and some emmc nand 2gb

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

i have 2 «th58nvg6d2ela48» one from japan
one from taiwan
i make this 32gb for me .used 2team group 16 gb same nand
so ,real flash 128gb

must be 4 or 8ce
example
is903
98 3c a5 93 4ce th58tft0dfkba4k
or
micron l95b
2c à4 e5 3c 4ce
