Dear N900 owners
I have a problem with my N900 wont boot after upgrade and reflash u-boot
©Early before phone has kernel power v53
Using xterminal apt get update upgrade command asks upgrade u-boot
But upgrade and flash finished phone wont boot any normal and kernel power mode
How to restore kernel power v53 without reflash and lose any app and sdcard data

quick reply .. may miss a lot of important information, but you won't lose any data:

first, why you have the problem: likely you no longer had the kernel modules belonging to the stock kernel, which is basically what 'flashing' u-boot flashes. So your N900 is not booting as by default, u-boot will boot stock (attached) kernel until you instruct it otherwise

so, simplest way is to use flasher tool to load the kernel for kp53. You can find zImage on the repos.

Then once you're in Maemo, you can fix your u-boot properly

sudo flasher-3.5 -k zImage-2.6.28.10-power53.fiasco -f -R


is that code solve the problem

and how to download kernel image
