- Verizon Razr Maxx HD
- Never unlocked (the unlock qfuse is NOT blown and the TZ is untampered)
- Previously motochoppered for root while running 9.16.6; edited sqlite db and froze some apps
- Phone ran 100% fine with no crashes/freezes/reboots from the original ICS release in 2012 up through and including build 9.16.6
- Before updating to 9.18.79 via soak test OTA, unfroze all built-in apps and used Voodoo OTA Rootkeeper
- Forgot to revert sqlite change before updating :
- OTA appeared to go successfully with no indication on-screen of any failure to apply any part of the OTA
Problem: Device reboots randomly, or semi-randomly:
- Overall it seems to reboot between 1 and 4 times daily
- It reboots more often when I am using the device to play music, perhaps every 2 hours
- via 3.5mm headphone jack or bluetooth
- Strangely enough it doesn't seem to ever reboot during weekends or while tethered
- It reboots when it's on or off the charger;
- It reboots when it's next to something larger;
- It reboots when I'm on the phone;
- It reboots when I'm asleep at home;
- It reboots when I'm on a plane;
- It reboots when I'm on a train;
- It reboots in the day, it reboots at night;
- It reboots when outside it's bright;
- It reboots in the absence of light.
- It reboots always, I tell you;
- What solution would Samsung sell you?

Here's what I've tried:
- I've tried freezing about 50 (yes, 50) apps using Titanium Backup. I froze almost anything that I could conceive of that might have any kind of background activity, whether stock or downloaded from the Play Store.
- I've tried un-freezing everything to no avail.
- I've tried a FDR, wipe cache partition, disabling SmartActions (as suggested over at XDA), and praying to Woodside Our Savior, to no avail.
Heck, I've even tried flashing back to 9.16.6, but that didn't work out (yet; SamuriHL is helping me ) for reasons I haven't yet determined. Overall it's pretty frustrating that I can't work out how this is happening and how to fix it. Any tips for this Dr. Seuss wannabe? :
X-Ref to XDA Forums, where a few other users seem to be having the exact same problem and a few more are having almost the same problem:
I'm posting it here because I think folks here seem much more knowledgable :
