N900 restarting loop
 
Hello
I have switched off my N900 and since then I cannot boot.
when I press the ON button it keeps restarting endlessly.
it just display the NOKIA screen (without vibration) and goes off and again on.
I have removed the battery for more than one hour, but it didn't help at all.
do I have to reflash?
Is there anything else I can do to avoid reflashing?
if I reflash will I loose all the installed apps and contacts?

please help me because I had a lot of valuable stuff there and of course I didn't backed up anything.

Re: N900 restarting loop
 
Have you tried charging the battery for a while before restarting? Something similar has happened to my N900 a couple of times, and each time it was due to a depleted battery.

p900 2011-06-10 20:32
Re: N900 restarting loop
 
yes, I have tried recharging the battery with an external charger.
I have also tried another battery without success :-(

Re: N900 restarting loop
 
yes there is way , it happened with me too , and some one said trying reflashing only kernel , but unfortunately i already had reflashed my device , try googling it .

Re: N900 restarting loop
 
Sounds as if your phone can't load the kernel.

Try flashing the kernel to the N900

Re: N900 restarting loop
 
Hello mate,

I had almost the same problem too. For me my N900 was fine but the battery pins were too wide to have a good connection. So if you have a something like a baby pin try to push the connectors closer carefully and try it again on your phone. It might make a difference. Let me know if it worked.

I retried using another USB port and windows say that cannot find the usb driver. that's strange because I was always able to connect my phone to that laptop

Re: N900 restarting loop
 
I waited more than 20 minutes but also it was pointless as there was no connection between the laptop and the n900.

can I find that driver anywhere to install it manually for windows 7 64bit ?

eefo 2011-06-11 19:25
Re: N900 restarting loop
 
lol you should have mentioned your windows bit before :p
search in wiki , or google with update firmware talk.maemo.org
and there you will see the procedure to flash your device with window 64 bit

p900 2011-06-11 19:31
Re: N900 restarting loop
 
I updated to PR1.2 and PR1.3 previously and 64bit windows on this laptop were just fine.

Re: N900 restarting loop
 
all I did, was a restart of N900 as it was ON for many many days and then I couldn't switch it on again :(

Re: N900 restarting loop
 
There might be a chance of a faulty USB cable. At any case you might want to recharge your N900's battery so that you can flash it.

Regardless of whichever OS you choose to use, the basic troubleshooting that you must do is to check if the OS enumerated (identified) the device. Under windows I'm sure its under device manager, under linux its via USB. Whilst the device is in flashing mode you will see the device is being identified something like 'Nokia Mobile Phones E-51 (firmware update mode)'. Also if the flasher is waiting for a suitable device and you have plugged in N900 already but you don't see the device being enumerated. You might want to try other ports on the computer and see if you can get the device to be identified.

Also I wouldn't personally suggest plugging N900 onto a USB hub when you are flashing, especially non powered/heavily used USB hub.

also, the n900 screen stays lit, writes NOKIA and shows the usb connectivity icon on top left.
I flashed mine N900 many times and I never plugged USB in the middle of flashing procedure.

First I plug device to PC by holding U key on the device keyboard and then connect the USB cable. I hold the key until I see USB connectivity icon on top right corner.

Then I execute flashing command.

If you are going to flash FW and eMMC (both latest) run first:

flasher-3.5.exe -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin -f

and then:

flasher-3.5.exe -F RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin -f -R


But if you are going to flash just FW (PR1.3), then run:

flasher-3.5.exe -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin -f -R


To flash just kernel (PR1.3) run:

flasher-3.5 -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin --flash-only=kernel -f -R


and to flesh just bootloader (PR1.3) run:

flasher-3.5.exe -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin --flash-only=nolo -f -R

Don't forget to type -R at the end of flashing command! Skip it only for kernel in the first scenario.

that's what the instructions they gave me say. to execute the command (part 6) and then plug the usb (part 7) found here

Re: N900 restarting loop
 
p900, VANILLA is not firmware, but eMMC content!!! You don't have kernel in there ! Use file's full names (don't rename them) to avoid confusion.

p900 2011-06-12 10:48
Re: N900 restarting loop
 
kolos which file do I have to use in order to flash the kernel? I changed the file name to vanilla in order to avoid typing all that long file name.

kolos 2011-06-12 11:02
Re: N900 restarting loop
 
Firmware is RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin and if you want to avoid typing you can rename it in firmware.bin or something similar. Don't forget to put -R at the end of flashing command if you will flash just firmware (or kernel, or bootloader).

p900 2011-06-12 11:13
Re: N900 restarting loop
 
so, I will type the following, right?
flasher-3.5 -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin --flash-only=kernel -f -R

kolos 2011-06-12 11:16
Re: N900 restarting loop
 
Yes and if you rename this file, the command would be:

flasher-3.5 -F firmware.bin --flash-only=kernel -f -R

Re: N900 restarting loop
 
I ended up with the following and now the phone is still plugged on USB displaying NOKIA with the usb icon ON and the display light is ON
do I have to do anything else? should I remove the usb and reboot the N900?

Re: N900 restarting loop
 
Very well! You can unplug the phone and try to switch it on.

If you will still have rebooting loops try to flash bootloader too.

flasher-3.5 -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin --flash-only=nolo -f -R

p900, don't need to send me any gifts. We're here to help each other, share experience, express our views and exchange knowledge.

Where is PQU, if it's not secrete?
