Help - how to get U-boot command to boot original kernel (as now stucked at loading v44 power-kernel)?
 
Somehow I accidentally upgraded to the latest power-kernel v44 (when updrading ALL in Faster App), and my N900 is now stuck at the boot-up screen (with U-boot) saying "Starting Kernel..."

Is there any command that I can give to U-boot (after interrupting the autoboot) to get it to boot the original OMAP kernel?

At the very least, is there anyway I can access the phone's memory to get back data?

[EDIT, 19 Nov 2010]
Have found solutions, which also include installing v45 of kernel-power, multiboot and even Nitdroid... see last page of this thread: http://talk.maemo.org/showthread.php?t=65411&page=9

I just made the same mistake and I'm stuck in the same spot...

Flash the kernel only (this example flashes the std. kernel).

Have you tried this?

To boot maemo instead of meego:

Hit any key to stop the N900 from booting into meego and write this in the console:
Code:

run noloboot

And it will boot into Maemo
- from the meego uboot thread

@DrWilken: I was already planning to reflash, but I think OP's original intention was to avoid that.

@cfh11: The boot loader is attempting to boot the correct OS, but it stalls at "Starting kernel". So, unfortunately "run noloboot" doesn't work.

The power kernel runs: run noloboot by default I think (You need to boot with open keyboard to override).

drdrewusaf: -> I said "flash the kernel only". That doesn't overwrite anything else than the kernel... ;) If You do it like in the link I posted.

Original info here.

Then you will reinstall all the programs for me?? (that was the true point) damn this u-boot... could not update some apps.. used apt-get update.. and this auto-installed... ****-off... it SHOULD NOT be instaled by upgrade even with extra-devel...

Please read the advice that's given you carefully, even if you're understandably under stress :-)

Flashing ONLY THE KERNEL as shown will NOT require that you reinstall apps or restore data. Just allow you to boot again as before.

welcome to my world of yesterday!.....I had to do a fresh install after I updated to v.4.2...I had multiboot installed as well.I`m sure there is a way to recover it , but I`m not a God concerning Linux, so the easy solution, format and do a backup restore.

Yeah, I understood that, it was still a PITA though...guess that's what I get for having a 64-bit OS.

It came back just fine after the kernel flash. Now I'm wondering if I should even attempt to reinstall Kernel Power...
