[Motorola Droid 3] mccoy51:
I am having the feared random reboots in my recently acquired Droid 3.

It is rebooting more than 10 times a day randomly, both when idle and when doing anything in the phone.

The only pattern I've been to able to catch is that around 30 seconds before a reboot, I loose phone signal (the signal strength meter is empty and showing a cross). WiFi keeps working until the reboot.

I am located in Spain and using the phone in GSM/UMTS mode, with CDMA disabled. Some times when I loose the signal prior to a reboot, I get a pop-up asking if I want to put the phone in "global" mode for it to search for CDMA signal.

I am using rooted Steel Droid 3 with OTA 5.6.890, but it happened with Verizon's stock ROM as well.

I have googled extensively for the last couple of days and did everything I have found about possible solutions:

- Factory reset and disabling Google restoring features on initial config (to prevent restoring WiFi hotspot data, alleged to cause reboots)

- Manually wiping all WiFi hotspot info

- Disable WiFi

- Running with no apps installed

- Formatting sd card

- Wiping user data and cache from Recovery

- Checking if the battery is loose, wedge a piece of paper to lock it in place

None of this have prevented or even alleviated the random reboots.

I'm fearing my phone might be a total lemon, but unfortunately as I am in Spain I can't return it and get a replacement. Anyway I have been reading that people have returned their Droids four or five times and still get random reboots in every new or refurbished Droid they get.

Other than that the phone works perfectly well, and I really love it. But having reboots when you are in the middle of something is going to get more and more annoying and I fear I will throw it out of the window sooner or later. I really need to solve this.

I run adb logcat in hopes of finding what is causing it, but it didn't see anything revelatory. Here are the tails of my last 3 logs before a crash:

But I have googled for libmdmctrl and there is only 1 result that has nothing to do with anything.

I am really in the dark, thanks for any help!
