For about the last week, my DroidX with the OTA GB leak installed (not rooted) has been rebooting when I plug it into or remove it from a charger or a USB port. When I plug it into the charger, the GPS icon appears briefly and the SeePU icon shows that the processor is maxed out, and then it full reboots to the red Motorola logo.
I have searched and read many other threads indicating that this is related to the SD card. The reboot does not occur when the SD card is not installed in the phone.
I have moved every app that was installed on the SD card back to the phone, but that did not solve the problem. I also wiped the cache from Recovery Mode which did not solve the problem either. I also tried setting the USB Manager to Charge Only.
I had this happen and all I did to fix was take cable to store and they replaced it for me and I haven't had this happen any more.... The cable worked for me. If the cable dont work then I would check port because this sounds like a short because it only does it when you plug or unplug cable.
I am on Froyo and my phone reboots when plugged into the usb port periodically. It started today when plugged into the charger of not letting me do anything including unlock the phone, however the power button worked and when I would hit it 2 to 3 times it would let me operate the phone.
It also randomly reboots whenever it feels like it.
I've never downloaded Bump, and I'm on stock unrooted Froyo; but I get frequent reboots (read: not every time, but maybe every other time) when plugging into my computer's USB. I don't let it bother me too much, but now I'm curious!
