D40, D50 and D70 phones on fw version 1.06
Digium phones start to boot, think they need a new firmware and so they download and install it, successfully according to the phone’s screen. Then they reboot, go into Reconfiguration mode, download the firmware again and reboot. Etc. ad infinitum, ad nauseum.
I found that if I put an old version of firmware in the second slot and do a factory reset, I can get the phones to come back to life. But that bank has version 1.05 and if I change it to something like the latest version 1.09, I get stuck in the boot loop again.
