Arg!!! Need help. I thought I had prepared well. I was rooted, so I unrooted, and flashed the stock recovery.img. However, the update failed and now it won't go past Fastboot.
If I attempt to manually fastboot flash anything from the 4.2.2 release, it fails. For example, if I fastboot flash boot boot.img I get Partition (boot) Security Version Downgraded preflash validation failed for boot.
I have a feeling that it partially updated and now won't take a flash of an older version. However, I don't have the newer .zip file to flash manually.
Any assistance would be GREATLY appreciated!
