I'm wondering if this approach can be used in my particular situation:
- I had a factory-jailbroken PW4, updated to 5.11.something
- For some reason I had to do a factory reset, then reinstalled most of the hacks (
but not the hotfix)
- It was living in an airplane mode ever after.
- One day I've disabled the airplane mode to sync time...
- OTA to 5.12.2 happened.
Now the
hotfix instalation (via Update my Kindle) throws 007 error.
But maybe there are some JB leftovers that'll allow me to enable PRE_GM_DEBUGGING_FEATURES_ENABLED__REMOVE_AT_GMC and downgrade to factory image.
I'm just wondering how risky is the attempt to downgrade. Should it fail right in the beginning, or it'll attempt to flash something and leave me in bricky state?...
