Re: Kernel power update, jamming on boot, panic help !
 

@Larswad,
after flashing to PR1.3 (kernel only) the power kernel was not available to me - so I believe it is uninstalled by flashing.

What I did after that was to install the stable version of kernel power, V42
@zimm,

what happens when you,

remove and reinstall battery - leave the phone off,
press and hold u,
plug in usb cable, don't have flasher running, just plug into a powered usb port.

Do you get the nokia logo with a small usb symbol in top corner?

@elipsoid: Thanks! And so when you went from the power 44 (or maybe 45) version to the Pr1.3, you flashed the kernel using the flasher3-5 over usb or did you do that from inside xterm on the device itself?
This time I'm double checking because I don't want to end up where some people did in here.

Impossible to get Xterm after the power44 upgrade - just stuck at U-boot and fails to load kernel:(

Grabbed PR1.3 kernel (not eMCC)
Flashed to PR1.3 on a linux machine over USB.
Then used apt-get to install v42, the stable version. All is well now and my device is back to normal, all programs and settings are as before.

This is the crucial part which a lot of people seem to be missing. The phone needs to be off when you want to get it into flashing mode. While it's off you hold 'u' and connect it via USB to a PC. That will get you into flashing mode. You shouldn't turn the phone on!
Once it's in flashing mode you run the flasher

I just fixed mine by reflashing the stock PR1.3 kernel.

These steps should get you there (assuming you're using windows):
1. Download and install the flasher from here: http://tablets-dev.nokia.com/maemo-d...-downloads.php
2. Download 'RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin' from http://tablets-dev.nokia.com/nokia_N900.php
3. Copy that file to C:\Program Files\maemo\flasher-3.5
4. Start -> Run -> cmd.exe
5. In the dosbox change to the flasher directory: cd "\Program Files\maemo\flasher-3.5"
6. Make sure the phone is off.
7. Open the keyboard and hold the 'u' key.
8. Connect the phone to the PC using the USB cable (while still holding the 'u' key)
9. Now you shoul be in flashing mode, the screen should show a Nokia logo and an USB symbol in the top-right corner.
10. In the dosbox run flasher-3.5.exe -f --flash-only=kernel -R -F
RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin
11. A new kernel will be flashed, that take just a second and the phone will reboot.
12. Done, you've got a working phone again.

The only step left is now is to figure out whether you want to reinstall the power kernel and which version to use in that case. But if you screw that up you can always get your phone working again using the above instructions, there should be no need to do a full flash or mess around with SD cards.

@elipsoid: Yes, just wanted to make sure. BTW, didn't know that when you had the 44 version you were one of those that got stuck in the boot. But ok, that explains it.

Not meaning to double post but I hope this would be helpful for those stuck at uboot: http://talk.maemo.org/showthread.php...d=1#post871473
Have a good one!

Re: Kernel power update, jamming on boot, panic help !
 

when i try the code for v42 my n900 says E: Version '2.6.28-maemo42' for 'kernel-power-flasher' was not found
Nokia-N900-02-8:~# .. any ideas?

Re: Kernel power update, jamming on boot, panic help !
 

Hmm, I have just checked it again on my device using the the -s switch to simulate, works fine for me.

First try this:
then try it again. You will get that error if for some reason you can not connect to the repository. If that does not work, that package may be in the extras-testing repository, just ensure you have it enabled.

Re: Kernel power update, jamming on boot, panic help !
 

I tried this but when holding "u", nothing happen... an idea ?

@babysugar: I see your still struggling since yesterday:(
Please do this first and post back exacly what you see:

remove and reinstall battery - leave the turned phone off,
press and hold u,
plug in usb cable, don't have flasher running, just plug into a powered usb port on the computer.

Do you get the nokia logo with a small usb symbol in top corner?
