Downgrading Readynas from OS 6.10 to 6.9.x
The title says it all. I upgraded and now I cannot compile virtualbox 5.1 using the linux linux-4.4.190-x86_64 kernel. I know the postings say do not, but is there anyway to go back in conjunct...

Thanks.
For anyone else contemplating the same thing:
I just tested this on a virtual NAS. It is not necessary to modify the time. Instead of modifying the length, delete one byte after the header to make up for the one added in the header. To verify everything is aligned, go to 0x4000 and verify that the ASCII data csums.md5 starts exactly at 0x4000.
I called the "update" 6.10.8. The file name doesn't matter, BTW, just how it identifies itself in the file header.
I did not see any immediate issues with access, but funglenn did see Samba issues, so consider that this downgrade may cause you to have to factory default to fix issues caused by downgrading Samba, and act accordingly.

THANK YOU! i used a hex editor and changed the version and padded the time as well.
As expected, the machine would not boot properly--the GUI would not load due to the changes in apache. However after a factory reset, it all came back up nicely as 6.9.4
now to wait for the resync and get back to work! i love this forum!
Sandshark you are amazing.
