[H955 6.0] Camera stopped working - Possible to Downgrade 5.1.1 / Reflash 6.0?

Hi,

i flashed the 20a version with lgup - everything worked fine so far but all of a sudden my rearcamera stopped working.

now i want to check if its something software related (20a is not a real final sofware) or hardware damage..
"reflash" with 20a and upgrade in lgup doesnt fix it.

is it possibe to get this phone back to stock firmware justin case i have to send it back to the seller or to see if it will work with stock firmware?

or are there any other ideas what to do?


thanks in advance
