find very old flash (some smi ) have 5 to 3.3 volt

ok so many people say cant find on smd market

how i find?

alex used flash extractor and tell me controler name and nand name \
example phison 2207 th58teg8t2jta20

Fortunately firmware 5.2.53 work with A19nm TLC ,15NM tlc toshiba and sandisk
good luck

Device Revision: 1100 is smi

dear roman

your flash is smi

connect 29+30 nand flash pin

Re Soldring nand pin

your flash nand pin is unplug solder again
flash must have a nand id
example
Flash ID code: EC1AA8DE — Samsung K9BFGD8U1M — 2CE/Single Channel [TLC-8K] -> Total Capacity = 32GB

also to day silicon power give RepairBox.exe you can download from site

connect gnd +led right side
to bootmode
after that try new mpall and
new bin file

in restore try restore or just format?
use restore 3.16 or 17

ok use uptool 2.89 and use clean flash
clean old firmware
and use mpall 5 and new firmware
but is risky

restore 3.9 is old!

use restore 3.15
if cant find
i uploded for you
and do not use mp or uptool

becuasr mpall 5
need 5.1.55

phison restore 3.15

hassan
use sss6690 v2.159
6690+toshiba 43nm d2

before mp
use sss safe erase
if cant
in feature setting
eraseallfirst=1

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 !!!!??
