I am new to the forum.
I have a pioneer dvr-115d and i was trying to make some dl backups but i wasn’t very satisfied with the results.Sometimes i have excellent results but not always. I had the last firmware 1.22 but using the imgburn the 12 the buffer wasn’t steady it fluctuates from 96 to 100%
So i upgraded the firmware to the primera 9.13 now the buffer is 100% .
I tried to restore to the original firmware 1.22 with dvrtool but i get firmware and device is unmatched.
I think i need the kernel file?
could someone help me, thank you
