Re: N900 Unexpected reboots
 

well i am sending it back to newegg for a replacement. i am really disappointed with this entire process. i am debating whether to just sell it once a new one gets in :(

Re: N900 Unexpected reboots
 

Bad hardware happens. Mine works and totally rules. Sorry yours didn't, but ones that aren't defects rock.

Re: N900 Unexpected reboots
 

i hope so, i am still on the fence as i can't sync it with my work email. when it works it does rock, but i hate my works webpage for email.

Re: N900 Unexpected reboots
 

Well, I kind of unsure what to do... my device reboots once a day... seems random.
Should I send it back or one reboot a day is not that worrying? Problem is that I bought it online so I have to send it back and also my retailer will only have units after the New Year.

Re: N900 Unexpected reboots
 

Hello
I am from Germany and my N900 had many reboots when I become it.
One Weekend 150 reboots. So I send it back and my new N900 has no Problems with reboots. Many people think that it will be a harware problem. Nokia Care have no informations about it.

Latest from Bug 6334 (random reboot 32wd_to)


From Aero Tamminen (Nokia)
Looks like the reboot problem will be resolved soon :)

Re: N900 Unexpected reboots
 

i don't have this problem but this is great news for other owners.

Re: N900 Unexpected reboots
 

Do you have any source, bsving?

I beg your pardon mate :D i misread your quote :$ shame on me^^

Re: N900 Unexpected reboots
 

After getting my N900 replaced last weekend (http://talk.maemo.org/showpost.php?p...&postcount=331) I've now had over 7 days without a reboot or any other problem.

I've been following the bugzilla reports for bug 6334, and it seems like some people have found a work around by adjusting the power management options in the Maemo kernel. Based on my own experience, I remain convinced that this is a hardware (i.e poor QA) rather than software problem. This is re-inforced by the fact that lots of other things on my replacement seem to work 'better' than on the first one I had.

YMMV, of course, as they used to say on Usenet... :D

Re: N900 Unexpected reboots
 

Well, Ican tell you that my device work much better also. Much more fluent screen etc, and I am simply doing the work around. As mentioned in another bug and thread, the rebooting messes up the PVR/SGX, making the system unstable. After ANY "warm" reboot, a cold reboot is recommended (turning off with the power button), as this will reset the SGX.

It certainly is hardware, as confirmed by the Nokia guy in the bug-thread. But, this is normal and simply a spread in HW specs that is not incorporated into the current driver. I mean, anyone who has done overclocking and been fiddling with wait states etc knows this.

Have faith, thatis my motto right now. :D

Re: N900 Unexpected reboots
 

So, essentially, I initiated the replacement of my rebooting device for no damn reason?

Re: N900 Unexpected reboots
 

Maybe, maybe not. I have done the same thing, but haven't sent mine in yet. With this fix, I easely go through a day without needing to recharge, so it has no practical consequenc for me. If this turns out to be unfixable in software, well then Nokia will HAVE to recall/fix them no matter what. If it is fixable in software, then no problem.

I bought mine on the internet, and right now it will take weeks, if not months to get a new one due to high demand and Christmas season. I see some stores will not get new supplies untill the mid of January. If I were in a position to just hand it over and get a new one right away, I would do it.

But, according to Nokia, this is likely to be fixed. They haven't given any promise, but they wouldn't do this in any case untill the fix is fully tested, and right now it is not. It is much more likely that this will be fixed, than not. Maybe not in the first FW update, but soon after. My experience with Nokia is that they allways deliver, but they seem to be in a habit of delivering a tad too early in most cases regarding high end devices. The N900 is no exception, and I believe that rightnow there is nothing fundamentally wrong with my device, that cannot be fixed in software.

Re: N900 Unexpected reboots
 

So what should we expect? A software release that would make our corrupted phones work as fine as those that had no reboot issues?

I'm confused. If replacing my phone allows me to get a new one, with no reboot probs and better performances, why would i wait ages for a fix that would prevent the rebooting but won't make my phone as good as others?

Re: N900 Unexpected reboots
 

You should read the bug-thread, but this is a snip from it where Aero Tamminen from Nokia answers this particular question:

Re: N900 Unexpected reboots
 

Well i'm participating the thread under the same id, but as i am a new user, i don't take nokia's team reactions as God's word and find difficult to know how much i can trust them, this is why i'd rather rely on experienced nokia's customers/users

(btw i'm french, so i'm sorry for my erratic english)

Re: N900 Unexpected reboots
 

I firmly believe that this issue can and will be fixed in an upcoming firmware update.

There was a similar issue with certain Apple computers and OSX 10.5 when that first came out. 1 in maybe 20 or so people were experiencing kernel panics. I was one of them. Since it didn't happen to everyone, many thought that it was a hardware issue. Yet somehow it was fixed in an update.

I have faith that this is a similar issue, and will be fixed in no time.

Re: N900 Unexpected reboots
 

Mine has rebooted from the start (MPD UK order, ordered 13th December),

Running "echo 0 > /sys/power/enable_off_mode" seems to have stopped the reboots, I'm going to wait for an update as opposed to sending it back.

Re: N900 Unexpected reboots
 

Got mine replaced. And the new one is also rebooting, albeit slightly less often.

As the only thing common the the devices was my SIM-card, I cleaned it with isopropyl alcohol. It might have reduced the reboots, but hard to tell.

Re: N900 Unexpected reboots
 

not sure if this will help. i recently boiught a used hp laptop and for no reason it would shut down after about 45minutes or so. so what i did was remove the battery. well it solved the problem. so if i had a nokia n900 i would see if i could run the device without the battery and plugged in. maybe the charge controller or the battery is faulty. its an easy test let me know what happens.

Re: N900 Unexpected reboots
 

I think new batch has improved something. I got mine 4-5 days ago, boot up out of the box, didin't install too much, 3 programs only, everything pretty much default, networks half 2.5G half wifi always on, skype and gtalk, 3 email accounts, 10G MP3, that's it, uptime now 4 days, never reboot, super stable, battery time is about 24-36 hours per charge, moderate used, about 2-3 hours web browsering, 1-2 hours music, some streaming video, 5-10 minutes phone call etc, every day.

Re: N900 Unexpected reboots
 

I have received my replacement unit yesterday in the evening and since then - zero reboots so far. In about the same time the old unit rebooted about 10-15 times. So I genuinely hope this issue is sorted for me - fingers crossed!

Also, I have an impression that new unit is slightly snappier and more responsive. But that might be a false impression since I didn't use N900 for few days.

Re: N900 Unexpected reboots
 

I received mine yesterday, and within the first two minutes its rebooted!

I've tried flashing new firmware, NSU didn't work it got stuck at 3 minutes, using flasher I changed firmware to GLOBAL and then UK variant, nothing. Then I tried flashing the eMMC and it just says changing device to flash mode and nothing happens!

Now it doesn't even do that, tried it under windows XP(32) and windows 7(64).

This is not good! I've just paid £500 for this and I have to wait for a replacement! I want someone to bring it to my house and swap it! I don't want to be without for 3/4 days or more!

This is definitely a H/W fault, I've changed the battery, changed the firmware, deleted all stuff preloaded on the device and still reboots! I am not pleased!

Re: N900 Unexpected reboots
 

it is sort of a hardware fault. but if u do the work around your unit unit will be vefry sttable and probally faster than a good one without the disabling of power off mode.

i am sure that this problem can be fixed with a fw update as its unlikely that is due to a faulty component but more likely a conponent that is varied and the driver isnt optimised for that variance..

i am happy with my device its super smooth with the workround. albeit i carry a spare battery

Re: N900 Unexpected reboots
 

Whats the workaround please?

I just tried updating the F/W on my openSUSE 11.2 PC and all I get is Unable to enumerate USB devices!

I've been waiting so long for this! EVEN the Nokia N95 and other which supposedly had their own problems I was able to fix with debranding etc. but this is a new kettle of fish, and it seems very different from the meamo i've been used to.

LSUSB gives me this:

Bus 001 Device 011: ID 0421:0105 Nokia Mobile Phones E61 (Firmware update mode)

it's really an N900

Re: N900 Unexpected reboots
 

Re: N900 Unexpected reboots
 

read the whole thread b4 you do anything id advise you do the perm fix..(it can b changed back)

Re: N900 Unexpected reboots
 

I just received a replacement unit yesterday and its rebooting constantly. Its actually worse than my old N900 (sent it in for other reasons than the reboot) but are we sure its hardware related? Should I send back the N900 again? Its spent more time at the repair center than in my hands so far...

reflashing it and putting it into R/D mode and taking it out of R/D mode did nothing. Still getting reboots.

Re: N900 Unexpected reboots
 

Hi,

Thanks, I figured it out. But it still didn't do anything. I think I'll wait until the new year for an update before I send it back.

Re: N900 Unexpected reboots
 

hi all,

after playing around with a device which kept rebooting (bootreason wd32_to) every 10-15 mins and after trying various workarounds like disbling some of the power management features I gave up and returned the unit for replacement.

Got a new one, restored the backup etc... no reboots for 4 days. So, my conclusion and suggestion to all of you who suffer from very frequent reboots is to get your device replaced as at least in my case I had clerly faulty HW.

Re: N900 Unexpected reboots
 

I'm experiencing also several reboots. :eek:
I disabled the screen vibration and seems to be more stable than before yet still rebooting sometimes.
It does not matter that I have one or many applications in use. It does not matter that the battery is full or almost empty. It does not matter that I play Mahjong or browse the net. It reboots at it's on will.
I just hope Nokia will release soon a new software killing all this "childhood" bugs and leaves us with a pristine terminal.
Any light on this will be greatly appreciated.
Happy New Year!

PS: Back in the day I said to myself that I was NEVER gonna buy any tech item in the first months of its release date. We all end up being the testers rather than the ones enjoying the product. Oooops! I did it again and I regret... Damn!

Re: N900 Unexpected reboots
 

Still reading through pages of posts....

I have been getting about 1 random reboot a day. Sometimes 2 a day. Seems like they happen when I a, doing just about anything. I had it reboot today when I woke up and slide the sleep slider to see what time it was. Love the phone almost enough to tolerate it but it sure is a bummer when your telling your buddy how sweet your new phone is and it reboots in front of him.

Mine is a preorder from Newegg and it has consistently rebooted itself 1-2 times a day since I got it.

Re: N900 Unexpected reboots
 

six do the perm fix, its worth it

Re: N900 Unexpected reboots
 

my first n900 had a non-functional internal microphone. had it for several weeks, it never spontaneously rebooted once. just got my replacement. the microphone works, but I've had 5 spontaneous reboots in the first 24 hours. :( seriously considering giving up on this device.

Re: N900 Unexpected reboots
 

i think it's a bug for now since it's still new =/

Re: N900 Unexpected reboots
 

thanks for the info! I decided to wait for a FW update instead of sending it back for replacement. Hope it's worth it:)

Re: N900 Unexpected reboots
 

I also had quite some reboots but all "sw_rst" as bootreason.

I knew in advance that the software was not really finished, could be buggy and could cause crashes ...

BUT

This device still runs linux, and one of the advantages of linux always was imo that you hardly have to reboot it, maybe just in case of a kernel update. So I think it's a big flaw the device reboots when there is a software issue. Can't it just try to kill the process causing the crash or fail gracefully without reboot?

Re: N900 Unexpected reboots
 

Any explain on why some devices do not reboot? The first unit i received did encounter such problem. However, the replacement unit i received do not encounter such problem at all, it is just perfect. Those who were lucky enough got their first unit in perfect condition. Why is that so? isn't all n900 running the same firmware?

Re: N900 Unexpected reboots
 

Mine just rebooted when I tried to connect to a public wifi spot and required a battery pull. Prior to this, it has never rebooted (2 weeks) as I rarely use wifi
