N900 doesnt work because of uninstalling Linux Kernel for power user
 

I tried to uninstalled Linux Kernel for power user via app manager but I couldnt uninstall it then I rebot my n900 and is not booting, now everytime i try to Turn on, charge, or plug usb it restarts several times... even i cant hard reset it via flasher :(

PROBLEM SOLVED
Uh thanks for Allah the problem solved without loosing any DATA
I really didn't believe that my device will work again

thanks to everyone helped me in maemo talk

here are the steps (I used Ubuntu):
1- charge battery via another device
2- install flasher and download firmware
3- in terminal type

Code:

---

sudo flasher-3.5 -F RX-51_2009SE_20.2010.36-2.003_PR_COMBINED_003_ARM.bin --flash-only=kernel -f -R

---

(RX-51_2009SE_20.2010.36-2.003_PR_COMBINED_003_ARM.bin) is the name of firmware and maybe yours is differ)
and (--flash-only=kernel) won't reset any data it will only reset the kernel
4- plug USB to computer and N900 (but let N900 without battery)
5- press and hold "u" and put the battery to N900 then it will say
Flashing kernel... done.
and N900 will boot successfully


then enjoy..

Reflash your device with the latest firmware. As far as I know the probable ideal way was to select the `Nokia Kernel' from the list of applications. I have done it once before and it works (though you'll need internet connection to the device however).

I think u can only replace a kernel with another. But looks like u have tried to uninstall a kernel without pointing an alternate. So this means there is no linux kernel to load.

Tried flashing only the kernel?

If I am not wrong, you have to click on Nokia-Kernel icon to uninstall Linux Kernel for power user.

Flashing Kernel only should do the job, not sure why you aren't being able to do so.

I can't reflash it
I turned off the device and I pressed "u" then connected to PC but unfortunately I couldnt do anything because same result happened :(

Re: N900 doesnt work because of uninstalling Linux Kernel for power user
 

try only flashing the kernel and this will do the job as already earlier mentioned...and dont worry flashing only the kernel you will not lose any of your files...

Big, Fat Warning!!!

The solution tim_de_wolf suggests will reset your phone to factory default. If you do not want to do it use the flasher to just flash a kernel http://wiki.maemo.org/Updating_the_t...rt_topic.21.29
