this controler real name is
MAS0902/MK8215
it was detected by the system and even mounted as a disk, but at the same time it was impossible to enter it, I did not find recovery tools through PID in the site table, and it seems that for this controller they are not helped by deep formatting using the HDD LLF Low Level Format Tool.
I suspect that the flash drive was previously flashed with firmware from another controller.
just support l74 intel /micron
and hynix 20nm mlc

Hi dear DavodAmirajam, hi all.
I try to change NAND (tsop-48) to new from old USB Flash drive Silocon Power (8 Gb) look like original chip, but it has not solve my problem. Maybe i kill processor (Rockchip RK 3066) after static electrick shot (shock)? A try to use hot air, good flux and check all pin of 48 — good contact. Or may be i need to set test mode for nand and connect many pins I/O to set Maskrom mode? I use many driver version and any programms (BatchTool and ROM Flash tool and RKDEv Tool ) many releases and many versions.

My best result — i can to load RKDevTool_Release_v2.86 boot, kernel, loader, parameter, misc, system and other parts of Firmware to RAM but when i try to load FW to NAND — it call to error IDB FAIL :((

Maybe i need to other programm or other driver or other firmware? But i try many of this.

May be i kill other details and it is reason — static electric may kill them?

WOW! IT'S GREAT) Thanks you my hero! My GoodRAM USB flash now work and capacity 128 Gb now correct.
I do test with «h2testw» software — OK sucess!
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 9.60 MByte/s
Reading speed: 16.5 MByte/s

IRAN — MY FAVORITE COUNTRY, THANK YOU VERY MUCH DEAR FRIEND, DEAR DAVOD AMIRAJAM. I AM HAPPY!)
Why am I suspicious of NAND PIN solder
IN AUTOMATIC MODE CONTROLLER DETECT ALL 2 NAND
MAY BE NAND 2 .NOT INSTALLED WELL
cs=CHIP SELECT
AD DE 94 DA Hynix H27UCG8T2ATR=8GB
IF YOUR DEVICE IS 8GB SO YOU HAVE 1CE .1 R/B
MAY BE RB,CE PIN IS UNPLUGED FROMM PCB
use hot aire +good flux.
if you not pro
give it to pro
if your nand is skhynix orginal
unplug pin problem
post here .in public may be help people

first post here screen shot
if you can bring ce1=60000mb
and if you change it to 120000 give you error
may be ce 2 pin is broked .resolder it again
in 50% 2ce flash= if 1 ce work ??? so solder again all pin .carefully
may be 1 nand unploged from pcb
use soldring all nand pin carefully +use good flux
