Can't poweroff?
 

Hi folks,

I hope this hasn't been mentioned before as I searched for it but nothing that quite matched. Somehow I can't seem to fully power my n900 off. If I press the power button and choose "switch off" the phone seems to power off, but then buzzes and immediately comes back on and begins an infinite reboot loop. The only way to stop it is to plug it into a charger. Is this normal?

Re: Can't poweroff?
 

Nope. Did you install anything from the unstable, likely to make your n900 freak out repository?

Interesting, never happened to me. Try rebooting from the terminal and see if the problem persists. From the terminal:
1. enter;
2. enter.

I had the opposite problem. After shutting down the phone and putting it on the charger, it will not start up unless I remove the battery and then put it back in.

@schettj: The only thing i've installed outside of the normal repos is dialcentral, is that known to cause any problems like this?

@x61: If I use root to issue the reboot command it seems to reboot just fine. It's only if I turn it off by either holding the power button down or tapping it and selecting "switch off" that it seems to have the issue. As best as I can tell it never seems to actually power all the way off, as it immediately buzzes and displays the Nokia logo (without turning on the backlight), then buzzes again and repeats the process over and over.

This is certainly a strange phenomenon. Run the code to give you when the device was last on.

Output from uptime:
16:28:37 up 1 day, 13:47, load average: 0.00, 0.00, 0.01

I powered the device off yesterday by taking the battery out, so I think it reflects that. It's the strangest thing, the moment I put the battery in the phone it starts an odd little reboot cycle even though I don't press any buttons.

superhyper that is the same issue I encountered. Be careful before it hits the reboot count total 17 or something like that before it bricks. Try starting in R&D mode, shutting off manually with the power button that way, then restart normally. Hopefully that will fix it.

this is the reboot problem..

send it back or turn pwoer_off_mode to 0- change this whilst powering your unit from a pc- not the charger

if it reboots more than 17 times it will brick and need a reflash.. to reset the counter just turn the machine off and turn it on again-

Thankfully I have not allowed it to hit 17 reboots yet. I was under the impression that my issue was not the same as the reboot issue everyone else was having (my device has never rebooted itself while it was turned on and booted up). It's an issue where it seems to immediately turn itself on when a battery is inserted without any intervention on my part and begin rebooting. I'll give R&D mode a shot and see what that does. Thanks for the input guys!

Placing the device in R&D mode seems to solve the problem, I can power the phone on and off just fine. When I disable R&D mode it immediately goes back to its odd behavior though. I'm not sure what's up with it.
