Lock out code or back door to 9412G and 7412G Bosch Control panels possible?

[D <865b5cd0025b5446449bdb269b2b3602_5841@xxxxxxxxxxx>]

Any help with unlocking or accessing panels that have lost power and memory
(Li Ion 3V) and now respond to RPS connection with 5017 :invalid datalock
message. Bosch wants what I believe to be an incredible $150 each to "refresh"
or refurbish programming. All I did was mistakenly store them without knowing
the "Achilles heel built in .
