Re: [help] N900 dont complete its booting & then it reboots
 

I'm not sure. From what I can tell on the Intarwebs, it may be that your battery is dead, although it seems perhaps a bit early (did you discharge it too deep or get it hot?) My n810 likes to reboot continuously when it's off and charging, and I think this is due to the battery being on its way out. I don't have an n900 to play with, tho.

Re: [help] N900 dont complete its booting & then it reboots
 

You shouldn't need to reflash. It sounds like a low battery - you can try charging it (make sure that the yellow LED is pulsing, and that the phone isn't vibrating & continuously rebooting - it may take a little while to start charging though). If it does keep rebooting then you'll need to charge up the battery externally, either in a compatible phone (e.g. Nokia 5800) or in a desktop battery charger (you can pick these up cheaply from ebay).

Re: [help] N900 dont complete its booting & then it reboots
 

no am sure my battery is not dead because it was like around 10% when i turned the device off and i woke up without turning on the device i charged it & it beamed ( the led flash ) as its charging i dont think its a battery problem :( :( :( :(

Re: [help] N900 dont complete its booting & then it reboots
 

mm the device is making this yellow or brown led normal flashing and its charging pretty normal by the looks of the led flash ....the problem is that am sure the battery is not so bad because its even rebooting why :( is there a possibilty that its dead device ?

Re: [help] N900 dont complete its booting & then it reboots
 

If you're sure it's charged, and it's still rebooting, then flashing is probably the only easy answer I'm afraid.

Re: [help] N900 dont complete its booting & then it reboots
 

Funnily enough, the very same thing happened to me just yesterday.

I can't say exactly what did it (though it was almost certainly my fault - I'd been fiddling with apps from extras-* all day) but even so, I had exactly the symptoms you describe. My battery wasn't low, but after rebooting the device voluntarily I had a reboot loop.

I charged up my Nokia *fully* - better to be safe than sorry - and followed the instructions on the Wiki:

http://wiki.maemo.org/Updating_the_tablet_firmware

A few (stressful!) minutes later I had a working N900 again, and an hour of installing later all my apps etc. back in place.

Re: [help] N900 dont complete its booting & then it reboots
 

I was thinking this was a funny coincidence too, but I'm starting to think otherwise. After I uninstalled a lot of apps yesterday I rebooted the N900 (the battery was full) and it got stuck in the reboot loop. Removing the battery didn't help to fix the issue, so I reflashed.

Re: [help] N900 dont complete its booting & then it reboots
 

If you use apps from extras-devel or extras-testing then it might be a error with the uninstallation script.

Re: [help] N900 dont complete its booting & then it reboots
 

If your battery is low (not flat, but low) it won't flash any how..
Normal low battery behaviour I've seen is to power off after trying to boot, not to reboot after trying to boot (ie reboot continuously)

Just because the charging light is flashing doesn't mean your battery is charged.. A good check is to try and press the U button whilst powering on.. if the screen stays dark, displays a Nokia logo and a little USB icon in the top right of the screen, it is fairly safe to say the battery is mostly full.. certainly full enough to flash and recover your phone..

if, however, the display lights up and the phone tries and fails to boot, you're going to need to find an alternative way to charge your battery.. someone else with an N900, X6, 5800 or 5230 would do since they all use a BL-5J battery..

Once you've got a charged battery, your device might wake up of its own accord.. failing that, it's probably time for a visit from mr flasher-3.5 to kick things into action

Re: [help] N900 dont complete its booting & then it reboots
 

hi
I already had the same problem. Only one way to solve it is reflash. sorry :(

Re: [help] N900 dont complete its booting & then it reboots
 

am certine that the battery is full now since i left home to watch a match and left it pluged to the charger now the led is green but offcourse its still with the same error so i think ill have to reflash it tomorow morning since am so tired u know i had the worst day ever i mad a car accident too :( thanks all it's really true that maemo is the best comunity ever :)
i will report back tomorrow what will happen with me :)

Re: [help] N900 dont complete its booting & then it reboots
 

sorry for my question but its better to know before doing anything wrong and regret.
when i reflash i only do this :
Download the Flasher for your device model: N900, N810, N800 or 770
In the same directory, download the latest firmware image for your device model:
for N900

Ensure the battery is fully charged.
Unplug the charger and switch off the device.
Connect the device to the computer via USB without turning it on.

or i have to do these also:
In order to flash directly from the XP/Vista/Windows 7 command line, follow these steps:

Download and install the latest version of Flasher e.g. maemo_flasher-3.5_2.5.2.2.exe
Download the latest firmware (.bin) file and save it to %ProgramFiles%\maemo\flasher-3.5\ (the default installation path for Flasher) or to the custom path of your choice.
Ensure the battery is at least half full.
Unplug charger cable and switch off the device.
Open the Command Prompt (Start then Run or Windows Logo key + R) and type cmd then press Enter.
Change the directory to the Flasher's path (TIP: Use the TAB key to auto-complete the commands and file-names)
cd "%ProgramFiles%\maemo\flasher-3.5" Hold the u key on the keyboard and connect the USB cable at the same time (details on the wiki)
Run the following command:
flasher-3.5.exe -F RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin -f -RReplace RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin with the firmware you wish to update.

The update will take approximately 4 minutes after which the N900 will reboot and display the Welcome Screen with Regional settings

Re: [help] N900 dont complete its booting & then it reboots
 

i have the same problem. Reboot even on regular charger.
i tryed to reflash, but i press "u" and when nothing happens, one time the computer found the Nokia USB ROM and get a error on Driver. Flasher still in "Suitable USB device not found. waiting."

I tryed Windows 7 x64, Windows 7 x86 and Ubuntu 9.10 x86. All the same problem. unless in Ubuntu, when i never get error with driver. but, doesn't works too.

HELP! :(

Re: [help] N900 dont complete its booting & then it reboots
 

mm i hope that someone here can find a solution for your problem too :( i really know nothing about re-flashing :( i hope that we will get our devices working soon missed my N900 :(

Re: [help] N900 dont complete its booting & then it reboots
 

wtf is Nokia USB ROM??!!
How can i install this driver?

Re: [help] N900 dont complete its booting & then it reboots
 

This is the part you need to do.

Re: [help] N900 dont complete its booting & then it reboots
 

Is your N900 going into USB flash mode (showing the Nokia logo, without the backlight, and a small USB logo in the top-right corner)?

Re: [help] N900 dont complete its booting & then it reboots
 

I'm not sure whether this is your problem (since you're still having problems in Ubuntu) but there's a specific section of the Wiki page that addresses potential problems with Windows 7.

I flashed mine using XP, so if you have an XP machine around, it's worth trying it on that. Also, if you have Nokia PC Suite installed, it will try and grab the device (even though it's broken) and prevent the Flasher from seeing it, so ensure you turn that off first if you have it.

Re: [help] N900 dont complete its booting & then it reboots
 

ok there is something i dont understand these 2 commands both i write them in the cmd in the pc or the 1st in the pc the second in the N900 or what exactly? and what exact version do u recommand me to flash ( my N900 was bought from US ) thanks

Re: [help] N900 dont complete its booting & then it reboots
 

All of this is done on the PC (except for holding down the U key - that's on the N900). You'll want to download and flash the latest version of the US firmware - it's clearly labelled on the site (RX-51_2009SE_3.2010.02-8.002_PR_COMBINED_002_ARM.bin).

Re: [help] N900 dont complete its booting & then it reboots
 

now my led flash is green so am ready to flash it right i mean that means that my battery is full ? .. btw i press the U the moment i plug the n900 to the laptop ? and i keep it pressed till when ? thanks :)

Re: [help] N900 dont complete its booting & then it reboots
 

If the light's green then it should be fully charged, yes. And you want to start pressing the U key before connecting it, then keep it held down until you can see that the N900 has booted into USB mode (the backlight will be off, but it should show the Nokia hands logo as well as a small USB logo in the top-right corner). Once you connect it, the N900 should power on and go into the USB flashing mode.

Re: [help] N900 dont complete its booting & then it reboots
 

RX-51_2009SE_3.2010.02-8.002_PR_COMBINED_002_ARM.bin this one next to it there is usa varient well my device was bought from the usa but i live in the middle east so is it better that i download the global one or its the same ? ( am now downloading the one which is varient for us)

Re: [help] N900 dont complete its booting & then it reboots
 

Press U on the N900 and hold it down while you insert the USB cable into the computer. KEEP HOLDING "U" until the flasher sees the phone. This means you should have already started the flasher app with flasher -R xxx.bin -F -r (not quite sure on the switches, haven't used it in a few days).

After your N900 is flashed and up and running... stay away from the extras devel repos. Even extras testing, for that matter. Sure, we need people who can test apps, but (and don't take this the wrong way), you're not one of those people. If you can't figure out how to reflash your device, don't even know about roofs and you think all the apps go onto the 2GB drive and if you panic like a little school girl if your N900 starts acting up, then the above mentioned repos are not for you.

Re: [help] N900 dont complete its booting & then it reboots
 

Nobody knows what the difference is between the variants. If your phone already had the US firmware then you may as well stick with that. Once anyone tells us what the actual differences are, you can decide whether to bother changing to the Africa/Middle East version.

Re: [help] N900 dont complete its booting & then it reboots
 

if the problem dont get fixed after i reflash ? i should install the eMMC and then directly after that flash it with that version ? because i read some other forms all are saying that flashing didnt fix it they made an eMMC which is also harder :S

Re: [help] N900 dont complete its booting & then it reboots
 

I think it's unfair that some people now have to go thru two kinds of flashes to really flash, but the eMMC flash isn't that bad. Yes, I would recommend you flash the eMMC and read the Wiki pages carefully (except ignore the place where it says you won't have to flash the eMMC if you have a production N900, because it is incorrect).

Re: [help] N900 dont complete its booting & then it reboots
 

dont forget to try several usb ports for reflashing IF it fails to start the flashing procedure. happened to me.

Re: [help] N900 dont complete its booting & then it reboots
 

i just did as u said Rob and now my device turned on didnt test the signal yet but the problem is that when i go to memory status i still see 1.68GB free for apps ( but all the apps are uninstalled is there anykind of error happened or i should flash the eMMC to have it like it was now after the reflash i still have mostly everything videos messages but i only lost the widgets and apps but i need to make it like factory what should i do :) thank so much !! really thanks finally i can use my device :D

Re: [help] N900 dont complete its booting & then it reboots
 

Yes, /opt is left untouched, so all the old installed apps will still be taking up space. If you're going to reinstall them then this isn't a problem, otherwise you'll probably want to reflash the eMMC as well (backup anything you want from MyDocs first though, as that will also get wiped).

Re: [help] N900 dont complete its booting & then it reboots
 

Well my phone got bricked too with the mid Februari update. I did manage to flash it back with the VANILLA.bin. I did however loose all contacts, conversations, apps, emails and so on.

Luckily I had a backup, but they didn't contain my conversations (why not? thats just stupid!).

I like this phone, but today bummed me out a bit. All of a sudden I am feeling a bit less comfotable with this Nokia. We live in an age of Gigabytes. Backup the hole shabang!

Well, I have to reinstall a ton of apps and so. *sigh* This phone used to feel so right..

I'll just wait with the big update at the end of Februari untill others have installed it. A shame it went like this though.

Re: [help] N900 dont complete its booting & then it reboots
 

so there isnt any problem reflashing the eMMC after i finish the eMMC i dont turn on my device right ? i mean i directly flash the new firmware too the newest one which was released 2 days ago? and is there any possible future failure if make this eMMC ?

Re: [help] N900 dont complete its booting & then it reboots
 

1st of all thanks for your help :) ... then i appriciate ur concern well its not that i couldnt find out how to do it my self or something but i never ever used anything near linux before i was always Windows Mobile user and i used to test alot of firmwares and everything without panic then changed iphone 3gs didnt like it and got my n900 so i was scared doing something wrong especially i live in a far country which dont have N900 thats why :) so am trying to learn more about the meamo and these stuff to be good for future releases :)
but again thanks for your help and i appriciate ur concer and will read more about the maemo and wiki's before doing anything stupid again =)

Re: [help] N900 dont complete its booting & then it reboots
 

thanks again all especially Rob1n i did an EMMC and then flashed a firmware i just booted up my device as if it is new from the nokia :) i really can't thank you enough bro have a nice evening :)
P.S : am heard a sound beap or punk when i turn my device off ( happened twice thats totally normal right ?
Thanks again :) :)

Re: [help] N900 dont complete its booting & then it reboots
 

Yes, that's normal.

Re: [help] N900 dont complete its booting & then it reboots
 

I had this happen to me this morning after intstalling Fuelpad!

Seems the only option is reflashing from skimming through this thread. Annoyingly, I'm out on a job for the moment! First time my N900 has played up :( I'm not even adventurous, only have 1 or two things installed from Testing and on from Devel (MaePad) which hasn't caused any problems in the days/weeks they've been installed!

Will flashing screw up my conacts?

I made a couple of backups previously on the device (which always seemed a bit odd to me!). Will flashing lose these backups?

I'm scared! :S

Re: [help] N900 dont complete its booting & then it reboots
 

Flashing the firmware will leave your contacts and backups untouched. Flashing the eMMC, however, will wipe your contacts and (if your backups aren't on the memory card) the backups as well. You may need to do both - start with the firmware and see whether that fixes it first though. If you do need to flash the eMMC, try powering off the N900 and connecting it via USB first - this may start it up okay in mass storage mode and allow you to copy off the data from the MyDocs folder first.

Re: [help] N900 dont complete its booting & then it reboots
 

Thanks, hopefully I won't be long on this job now. And can get home and try and flash my N900 again! I now hate FuelPad! lol!

Wish I'd done a backup to the SD card now, only ot it working a couple of days ago!
