N900 keeps turning on and off!
 

major problem!!! my N900 suddenly turns on and off...it'll turn on and then few secs after it'll turn off. I can't do anything on my phone..it just keeps restarting like crazy! I took out the battery..took out sim...and everything...problem still persists...what should I do? it won't let me access my phone at all :(

Re: N900 keeps turning on and off!
 

i think u have dead battery, i was having this same issue with failed batttery

Re: N900 keeps turning on and off!
 

ok I was thinking the same...because lately my battery had been draining quicker than usual...and I've had my N900 on the same battery for more than a year and a half now..and well perhaps it just died? Planning on ordering a new battery asap. Let's see what happens...where'd u order ur batt from?

Re: N900 keeps turning on and off!
 

Before u get a new battery try switching your phone on with a different battery same battery of another phone or from someone you know with same battery as i think its on a reboot loop where you might have to flash your phone! If your phone works fine with another battery than its your battery if you get same problem then you definetly need to flash it! Some software has crashed your phone and made it go into a reboot loop!

Re: N900 keeps turning on and off!
 

Are you sure you didn't mess up somthing important like system files?

Re: N900 keeps turning on and off!
 

nope, last thing I did before this reboot happened was to open the browser and it just went crazy from there. I plan on testing a new battery tomorrow, however if the problem persists, how would I flash my phone if it keeps restarting by itself as soon as the battery is put in?

Re: N900 keeps turning on and off!
 

Perhaps if you keep holding U from even before you stick the battery in it will go straight into flash mode?

Re: N900 keeps turning on and off!
 

The full information how to flash is available on wiki just do a search for flashing firmware and off you go everything you need and how to is on there its quite straight forward too! good luck!

Re: N900 keeps turning on and off!
 

Perhaps that Backup OS thing could be helpful?

Re: N900 keeps turning on and off!
 

alright will give it a try....i'm hoping the issue is mainly due to a dead battery and nothing else...if not, i'll look up on how to flash.

Re: N900 keeps turning on and off!
 

If your device turns itself on and off whilst showing mostly nokia logo during the on intervals. That's what you call a bootloop.

Bootloops can be caused in various ways including deleting critical `system' files, installing programs from extras-devel repository without reading or understanding what the program is used for, etc.

Unfortuntely to cure such symptoms easily would be to reflash the device.

Re: N900 keeps turning on and off!
 

ok I tested out a new battery and it still didn't work...so it's def a software problem! :( I've never flashed N900 before....let's see how this goes....after the flash will it wipe out everything? files, programs, pics,vids,contacts etc? I don't even think I have a back up...

Re: N900 keeps turning on and off!
 

You might wanna try just flashing rootfs at first see if that is enough to at least let you access the stuff you wanna backup. Read the details on the wiki, and triple check everything before each step.

Re: N900 keeps turning on and off!
 

Btw, i meant Rescue OS, sorry 'about that.

Re: N900 keeps turning on and off!
 

finally fully flashed my phone. I used this site to do so. http://www.mynokian900.com/2011/03/f...-my-nokia-n900

Also I installed that security update that was supposed to include portrait mode and some other features, but my phone is still in landscape mode?

Re: N900 keeps turning on and off!
 

The security update is just a security update, no other features. If you want potrait mode, install CSSU.

Re: N900 keeps turning on and off!
 

I had CSSU before, and because of that something happened and my phone went in a reboot loop....how about if I just do this for portrait? http://talk.maemo.org/showthread.php?t=74980

Re: N900 keeps turning on and off!
 

You could also do that for a potrait desktop of course.

Re: N900 keeps turning on and off!
 

That modified hildon-desktop's been merged into CSSU.

I recommend flashing to PR1.3 GLOBAL firmware, then installing CSSU on top of that.

The PR1.3.1 security fix is already in CSSU as of the 20.2010.36-maemo16.8 release.

N900 bootloop
 

I need help. experinecing bootloop on my n900 after i tried to uninstall power kernel seetings.
i am trying to flash but the device keeps vibrating, showing the nokia logo and the usb symbol in that sequence in a cycle, and hance i cannot flash, please help.

Re: N900 keeps turning on and off!
 

So here is my bootloop problem. I decided to do the swap on SD which is a great idea in theory, but if the cover ever comes off it crashes your system when swap dispersals. As we all know serious system issues come up when the system is crash stopped. I had one N900 end up with a keyboard LED get stuck, flashing didn't help. What this means is that the N900 can apparently hold errors in hardware after crash halts which flashing wont fix.

So intro over...

I have a reasonably new N900 bought at that NewEgg closeout sale. Had a few occasions where my cover popped off or a unstable app crashed the phone. Now I have a N900 which will often bootloop even after a 5-6 clean USB flashes of first stock Nokia vanilla and then stock Nokia combined images today. First boot works fine but after I get things installed to use a working backupmenu image or even rebooting after installing some repos or installing CSSU the bootloop returns.

(edit) I left it sit without battery for 10 min and I got it to boot...
