PHISON 2251-09-26 AFTER BURN IC USED 2251-09-V



AFTER BECOME 3D FLASH COMPANY HAVE A BIG BENEFIT
FOR EXAMPLE

FOR 32GB USB3 .SILICON POWER MARVEL M50

IN 2013 =SM3267 +ORGINAL INTEL L74 (4CE)
IN 2014=SM3267 +SANDISK TLC (2CE )

IN 2020 ALSO LOW COST CONTROLLER +DOWNGRADED NAND 32GB (ONLY 1CE )

OK 1CE TLC ?? MAXIMUM WRITE SPEED IS 10MB (SOME SAY OH NOT 8T23. I WORK 2 YEARS 8T23
IN 3D FLASH JUST INTEL MICRON MLC L06 IS VERY GOOD EACH 1 CE (MLC 16K 3D CAN WRITE SPEED 30MB
HOW EVER

after extract nand i read it (8t22 98 3c 98 b3)
install on big controller 2251-09

8t22 can work vccq =3.3 volt
but do remember

intel n18 l06 and b16 b17 vccq must 1.8 volt

if you put 3.3 on im flash may be nand is destroyed

in smi r44 for 3d (1.8)volt

but i just install nand and work normal and
it is very easy

and copy all important file

WE NEED 2251-09-26 DATA (HAVE IMPORTANT FAMILY WEDDING MOVIE

I HAVE ANOTHER 2251-09 BUT THIS MODEL HAVE LM3020 IC TO 1.8 VOLT VCCQ

SO FIRST EXTRACT NAND FROM 2251-09-26

AND INSTALL ON OTHER PCB

MAKE SSD AT HOME JMF606



I HAVE A FEW OLD BAD SSD
SOME PE ARE DONE (PROGRAM ERASE CYCLE END (EXAMPLE INTEL L74 HAVE 5000 PE)
SOME CONTROLLER DESTROYED BY ELECTRONIC SHOCK
BUT I NEED ONE SMALL HARD DISK TO MY DELL D630 OLD LAPTOP

FIRST MUST KNOW SSD LIKE USB FLASH PROGRAM BY CONTROLLER
AND WE WORK WITH SSD CONTROLER COMPANY

MY SSD CONTROLLERS IS MARVEL,SANDFORCE ,AND JMICRON

FIRST THING FIRST SEARCH INTERNET TO FIND MP (MASTER PRODUCT SOFTWARE )
I JUST FIND FOR JMICRON 606

OK LETS START

Fix COB FLASH



hi again

to day we have 4GB HP flash
this flash is not working

First step we must check Fuse

1-use multimeter
connect black wire on flash disk 5volt and red wire on GND show 630~650
if show betwen 500 and 650 5volt fuse is ok

if see the range your flash 5volt fuse is safe

if not try to found 5volt way


2-test DP DM

also use multimeter to see range betwen dp dm you must see in 1 second 1200~1500



ok we know test dp and dm

to day hp 4gb 5volt show «0» we found 5 volt way and use wire to connect 5 volt

in this picture i show the dp dm and 5 volt line

solder 5volt to line and flash is worked again

this flash have important data and we fix it
with out any flashextractor or pc 3000

FIX Innostor AND PHISON 64PIN Hardware Problem

IN Innostor FAMILY


IN PHISON USB3 64PIN 2251-03-Q ,2251-07-6


HI again
too many people have Innostor flash memory
and so many people emailed to me and have this problem

some ic «eml3020» is crashed and usb is not worked

eml3020 is dc to dc convertor


Innostor like a very old flash havent inside voltage convertor

as we know nand flash used 3.3 volt
but usb voltage is 5 volt

some flash like 2251-50 or other have dc to dc convertor but Innostor used em3020 to create 3.3 volt

— ok

lets test rule

use multi meter
1-is 5 volt fuse safe? ok go to next level
not ok > change fuse

2-Between DP AND DM must multi meter show (900-1700 ohm )
if not show change dp and dm fuse

3-test L1(Fuse)

4-output eml3020 is 3.3 volt?

if not

try find on old flash memory have 5 to 3.3 volt convertor
