Hi. I followed the instructions in the backup loading basics sticky last night and installed the patch IOS236 and then used the cIOS installer. The problem is, I had rev 17 and 20b side-by-side because I could not get them to work initially, and now I don't remember which one I ended up installing. Is there a way to get a snapshot of what IOS/cIOS I have installed and what version or revision level of each? Also, is the only way to revert the changes by restoring NAND backup? Thanks.
