I am currently using an external JLINK to program the 9160 module, after adding read protection. Unable to recover using nrfjprog, report the following error:

ERROR: Recover failed. Please make sure that the correct device family is given and try again.

Hi,

Please make sure that the correct device family is given and try again.

 Could you please try setting the family of your device when using recover:

nrfjprog --recover -f NRF91

Best regards,

Marte

Hi,

Please verify which version you have with nrfjprog --version.

Could you please try 

nrfjprog --recover -f NRF91 --log

and attach the log here?

Could you also try the solution posted in this case (but change nfr52 to nrf91 in the script)? Remember to power cycle the device while running the script.

Best regards,

Marte

Same phenomenon

I think this is a bug. Performing nrfjprog --recover after nrfjprog --reset will trigger an unrecoverable bug, which can be recovered after reopening the command line window or powering off the module. Can you guys try to solve this bug?

The problem can be reproduced on thingy91. What I burned is the program of at_client, after executing nrfjprog --reset, thingy91 will light up red and green lights. The recovery operation cannot be performed when the light is on.

Hi,

Can you please verify which version of nrfjprog you have with nrfjprog --version?

This bug has been reported before, but should be fixed in nrfjprog version 10.11.0. Please let me know if this isn't the case so I can report it.

Best regards,

Marte
