Hi all,

I purchased an XPR 3500e that unfortunately has the latest firmware installed, forcing CPS 2.0. I'd really like to downgrade to the previous firmware so I can patch 25khz channels and stop pulling my hair out when the CPS hangs.

I know that this is possible and I believe I have all the tools:

Depot 14 installed
FlashZap PCR installed
Tuner settings backed up

All that I'm missing is the firmware itself, I believe, and a guide on how to pull this off without bricking the radio would be nice

I'm happy to share the above tools if anyone can help me find a guide. When I search in Depot I get an error and no results.
