I have updated firmware from r802 to newest one, r806
With original file from Samsung web site, r806com.bin
After that it does not write nor CDR nor CDRW
I returned firmware to r802 but without any success
I tried also r803, r804, but with the same result
Can someone dump firmware from SW-252FEN (not 252F) please ?
I think that firmwares 252FEN and 252F are different
