SOME CHINA A19 MLC DDR LOOK THAT FIDE
WHY MP IS SDR MODE

BECAUSE I INSTALL SDR NAND IN CHANNAL 0 PLANE 1
PHISON MPALL CHECK CE 0 AND IF DDR MP DDR
BUT ONE CHIP IS SDR
IF MP IS GOING TO DDR MODE FLASH NOT WORK SAFE
BUT I INSTALL SDR TO CHANNAL 0
TO MPALL RECONISED ALL 4 CE TO SDR MODE

SMI MPTOOL HAVE A CHECK BOX TO FORCE DDR
IS903 MP TOOL HAVE A DDR CHECK BOX

BUT PHISON MALL AUTOMATIC CHECK NAND
IF ALL NAND IS DDR
MPALL DO DDR MDE

IF I HAVE 2 NAND DDR SPEED IS READ 150 WRITE IS 50
IF I HAVE A DDR 98 DE 94 93 76 D7 4CE READ IS 200 MB WRITE 100MB


SPEED IS

ONE SIDE SDR
OTHER SIDE IS DDR
BUT SAME ID

SO DO MPALL AND FIRMWARE
SO I MAKE 2207 AND INSTALL 2 MODEL A19
2207 HAVE 1 CHANNEL

TT57G2LAPA IS SSD NAND 98 DE 94 93 76 50 MLC TOGGLE DDR

AND SOME MODEL IS NON DDR
In 90% fuse change ,crystal change or do DM fuse change
Flash become work
I never buy PC 3000
If controller dead?
Try to change controller
Old band never lose data
Almost if have a problem
Controller problems
If you read my old article
I change 2232 PCB and save data
use factory driver for smi
install factory driver
and after connect use smi mp tool

to re frimware it
good luck
why you open the flash cover?
your problem is software

also we haave not fw65v5050.bin
so wait until we get that firmware
first use factory driver

if cant see driive letter

connect gnd+led left side

read old Article
sandisk or Toshiba 19nm mlc downgraded
but soldering nand is unplugged
flash I'd error!
you see I'd is not normal
solder again nand pin
you have hardware problem!
note:
some time we can't see the drive letter
this mean flash firmware is crashed
so we closed nand data pins (29+30)
or do my way
after connect +5 volt to controller pin
nand I'd is changed to 04 04
but before do firmware
cut the wire
2250 2260_2261_2267_2268
and
SMI 3257 family work with my way
use wire and solder pin (I show in top picture)
after soldering wire connect to PC
if you see 2268 pram
cut the wire (but no disconnect flash)
download uptool ver2093
go setup
first in user interface
enabled clean button
after do that
in main menu click clean flash
to erase all the old bad firmware
second
after clean flash
firmware again
in settings flash memory
downgraded flash
low level
smart test
ecc 12

good luck
4200 is phison 2251-68
before connect to PC
hold 29+30 band pin
to get the ROM code mode
if you real old article get that
after see the drive you can
re firmware uptool 2093
and capacity mode
band is downgraded
2c mean to capacity mode
to day i fix 2207+a19 tlc toshiba

but to day just update ony isp And Dont clean nand in uptool

put this line in mp.ini

ISP ONLY=1
