CCR 1072 password de admin

My CCR 1072 keeps losing the admin password. I have to restart it to fix the problem. This has happened twice in 14 days.

Help!!

RouterOS version?

The internal memory is corrupted. Do a /export show-sensitive file=myexport and a backup, save it elsewhere,
then do a netinstall and reconfigure the device with the export. Using the .backup file might also cause the problems to reoccur.

version v6.49.8
If the internal memory is corrupted, it can be fixed by resetting the device. Others recommend updating the firmware to the latest version. My fear is that this will worsen the problem. Thank you for your response.

No.
Reset does not clear complete internal memory.
Netinstall does.

And Netinstall lets you easily install any fresh/clear version of ROS you wish (dwon to the factory minimal supported by a device). No need to upgrade/downgrade.
