Random reboots
 

Hello!

My freshly bought N900 is not cooperating with me ;(

I get random reboots - on a freshly flashed, on CSSU T, on CSSU Thumb - no matter which I flash the reboots come again.

cat /var/lib/dsme/stats/lifeguard_resets

shows:

/usr/bin/systemui: 1
/usr/bin/hildon-home: 2
/usr/bin/camera-ui: 1
/usr/bin/ohm-session-agent: 2

cat /proc/bootreason

Any help what to do with this problem?

Maybe this is of some help, though the reboot problem should be fixed :

(My, that URL just looks weird in this context)

A bit dumb but cheap suggestion to try: a new battery.

Re: Random reboots
 

It was a battery that was causing my random reboots. So might be worth a try.

Re: Random reboots
 

My wife's Lumia 520 has the same battery so before buying a new one I will do a secret swap for testing ;)

The strange thing is that sometimes a get a reboot under heavy load with many apps running and sometimes it happens just with one thing opened.

Re: Random reboots
 

I had random reboots on my n900 with dying gsm. It was long time ago so I am not sure but probably with tablet mode on there was no problems (except broken EMMC :P).

Re: Random reboots
 

Do you have a SIM card in that phone? That "out of the blue" reboot may be caused by a sudden spike of current caused by e.g. a call or an SMS about to be received.

Re: Random reboots
 

Yes - there is a sim but it is disabled by default - I use an app to turn the phone into tablet mode. I just turn it on to receive sms from my bank, the turn it off.

Re: Random reboots
 

Everything above said is possible.

I always go for some isopropanol alcohol to clean up contacts.
And in this special N900 case you may bend the "spring" metal clips, holding the battery, a bit inwards.

Good luck...

Re: Random reboots
 

Yep, start with bending those springs a bit.

Re: Random reboots
 

Funny thing - I wanted to do what you proposed so I have pushed the power off buton and selected switch off, and the phone rebooted by itself instead of turning off...
The second time it turned off.

The contacts look like brand new so I just bended the clips. Will report later.
