How to restore a flash?

[hack3rcon]

Hello,
I have a USB flash drive with ChipsBank chipset model "CBM 2098E". I used CBM UMPTool and changed its model to anything else, but after it my USB Flash drive is not detected by system. How can I fix it?
I tried to reformat it with "dcfldd" :

Code:

# dcfldd if=/dev/zero of=/dev/sdc1
# mkfs.ext2 /dev/sdc1


After it:

Code:

$ sudo file /dev/sdc1
/dev/sdc1: Linux rev 1.0 ext2 filesystem data, UUID=3d08c314-aa88-43fb-a8c0-66226fa8ff5d (large files)


But, I can open and mount it
How can I restore it?

Thank you.
