I successfully downgraded a KOA2 from 5.14.3.0.1 to 5.14.2.

Note:I was already successfully jailbroken at 5.14.2, then received the OTA update to 5.14.3.0.1.

Steps: re-installed hot fix just in case, reinstalled KUAL, then used the downgrade extension to go back to 5.14.2.

Errors experienced:

* after copying the 5.14.2 bin to the root of my kindle, I received an error something to do with an incompatible update file. Tried downgrade, and it rebooted and no downgrade, but copying over the bin the second time worked fine. Successful downgrade.

* amazon sneak-attacked me and auto-updated me immediately after my downgrade. After the OTA update, I turned on airplane, reinstalled KUAL, re-applied downgrade (same error as above). After downgrade immediately applied the renameOTAbin extension: https://www.mobileread.com/forums/sh...&postcount=174.

Downgrade working and persisting.
