Here's the delta for 2.3.0 E6:
conf.cfc.delta.e6:
[(1068, '\x02\x04'), (1116, '\x03\x06'), (5443, '\x04\x05')]
Unfortunately it has the same size as the e5 config file, so my script can't auto-detect. Easiest is to just take the v0.4 hack, and overwrite conf.cfc.delta.e5 with the e6 delta.
Do it on your own risk!
47MHz, let me know if you can't send the bricked one back to service.
