Just wanted to renew my Samsung N500 firmware. After "erasing" it was flashing up to 100% and giving me the following.

Bad_Resp_Chck: 08 ...

I've tried couple more times, then checked "New Flash Layout mode" and tried to flash again. The process completed to 100% and gave NO error. Then tried to flash second flash file (OGM) and what a surprise:

Mobile Boot Failed

Now I am not able to do anything with UFS box any more...
Please help me to understand the problem and resurrect the phone guys.
