Z10 keeps rebooting on its own 10.2.1.2977 version installed

Question

Reboots about twice per day randomly on its own.  Has been getting worse lately.

Answer 1

Hello,
First, please confirm your OS level...is 10.2.1.2977 your "Software Release" or your OS Version? The OS version is the number that is the most important.
If .2977 is your OS level, then it is not terribly current. There were at least two more versions, in the .3nnn range, after that, as well as 10.2.2.1531...all of which are more stable than what something as old as .2977 would be. So, rather than trying to fix what you have, I recommend you instead update your device to something more current.
Via the on-device as well as LINK methods, you will be restricted to what your carrier has allowed:

But, via Sachesi or AutoLoader, you will be able to use any version for which you can find the proper files:

Given what you describe, I would recommend you use the AutoLoader method, and indeed use this process:
Take a full backup via LINK
Manually copy all of your data files from both Device and Media card to your computer
Fully document your configuration (email accounts, screen layouts, configuration preferences, etc.)
WIPE your device
Load your OS via AutoLoader
WIPE your device
Restore from the backup taken
If things operate normally, then stop here
If things do not operate normally, then redo the process starting at step 4, but at step 7 restore only your Settings and nothing else, and reconfigure the rest manually from the documentation you created in step 3.
If things still do not operate normally, then again redo the process from step 4, but skip step 7 entirely and instead manually reconfigure everything via the documentation created in step 3
Good luck and let us know!
