Can that old firmware run the KUAL installer bin using "Update My Kindle' option?? (if using that way the bin file doesn't go into "mrpackages", it goes into the root level of kindle drive)
You installed DevCerts keystore bin that way?
As for MRPI & ;log mrpi : you probably should reinstall the hotfix bin (using Update My Kindle)? One thing to have in mind is that if you reinstall the hotfix bin (from NiLuJe's Snapshots thread) you're gonna need to also reinstall DevCerts keystore bin again
after the hotfix because hotfix installer hasn't been updated / repackaged to have the new developer.keystore
