Failed Recovery, MODM7AE70 - what am I doing wrong?
Posted: Wed Apr 28, 2021 7:29 pm
I've got a MODM7AE70 module that became corrupted, and now even the recovery procedure doesn't seem to revive it.
I've got the module installed in the MOD-DEV-70CR base, powered through the mini USB. I'm following the recommended recovery process from the NB Docs.

- During recovery process, with the jumper in place, eventually led D2 becomes solid and led D1 blinks around 1 Hz rate. Then I remove the jumper.
- When jumper is removed, led D2 blinks around 2 Hz several times, then appears to reattempt booting or something, and repeats. Pressing the reset button has no effect.
- I get no comm through the USB serial connection with MTTTY at any point in the above process.
