An approuch to the solution
Hi all, I'm new here and I would like to share my experience with my Atrix
A few months ago I bought a brand new Atrix from Amazon; this was an unlocked ATT phone that works perfectly for 3 months; then the phone began to restart itself with no reason and without any logic.
So I try everything...
1- I change the SIM card
2- I Reboot to factory defaults
3- I wipe data to factory
4- I wipe the system
5- I installed CM7
6- I went back to ATT 5.141 version
9- Now with ATT firmware version 5.91
Nothing works, and nothing fix the restart problem. In my case the random reboot wasn't the only one problem, also my phone lost connection with the mobile company network, so the phone become a little tablet.
So for those who can't connect his phone to the mobile company network, there is one quick solution: (you need to unlock the bootloader)
1- format Dalvik cache
2- Format cache partition
3- Format battery statistics
Then restart the phone wait for it to reconstruct the Dalvik cache again, and then your phone will connect to your cellphone company network; this will no fix the restart problem but you will be able to use the phone as a phone when it put itself in "flight mode".
I think that this restart problem is due to some buffer that is being overloaded, or something like that, I will keep searching and trying to solve this by my self.
If I have any advance I will post it here again.
