EM7565 Firmware Gets Corrupted

Hello,

We are currently using Sierra Wireless modem models EM7565_1104207 and EM7565_1103520 with FW SWI9X50C_01.08.04.00. Recently, we have encountered issues where the modems enters a failure state where the firmware becomes corrupted. We have looked at a few modems sent to us that are failing during the repair process.

We believe the problem is caused due to power ups, and downs or a firmware issue. We have been able to connect to these failing units, reload the firmware and they seem to come back to life.

Has anyone encountered or observed this issue before? Or is there any firmware update that fixes this issue?

Have you tried to redownload firmware and see if it can recovered?
