Unfortunately since some hours I have a N900 which no boot anymore (reboot loop) and I am trying to recover it without full reflash.

I have executed :

• dpkg -i u-boot-tools (installed but not configured)
• dpkg -i u-boot-flasher (install failed)
• cd / && tar -xf /home/user/u-boot-images.tar.gz
• u-boot-update-bootmenu
• dpkg -i kernel-power-modules_2.6.28-10power49+pre50_armel.deb (which has removed power kernel v49 modules)
• flashed manually new kernel
• rebooted

Then phone has never completed boot process.

Tried many kernels but at some point it always reboots with all kernels (stock and power v50).
Tried RD mode and Kernel with FB but no results

Fortunately multiboot menu is still operative and I can launch backupmenu and its ssh shell, the problem is to find out what is the problem that causes reboot
