Yes, I too faced the same issue with my cech4008A on 4.81.
Uncheck 'NOR' and check 'eMMC'.
After PS3 settings reset, ROP was fine.
Which game are you trying?
Well, I don't know if these might help...
1.) Reconnect the USB after launching the exploit page.
2.) Select File Size after changing TitleID in Destination.
------> Do not change the size , leave it as (0x10190).Click Set New Size.
Hmmm not sure but I think both are same, machine will add the 3 zeros by itself anyways I think. Yeah, better try with another ready-to-inject game, probably a smaller one like Duck Tales from pspx.ru
