Hey folks:   I tried to do a manual update to 6.9.2, and am now having boot issues.  I have worked through the troubleshooting page on the wiki but am stuck.   Here is the process I followed -     connect the flash drive to a PC/Mac     make a backup of the flash drive in case you want to be able later revert     download the zip of the release you want to use from the unRaid download page     extract all the bz* type files overwriting the ones on the flash drive
