I wrote the image of MeeGo onto my 2GB MicroSD and i once flashed with a
sudo flasher-3.5 -l -k <kernel> -b
and found it was working fine.. Then reverted back to Maemo.

First I was using bootmenu. Now i removed it and installed MultiBoot and the very next reboot made me stuck

I cant find any kernel listed down,(not even the native maemo OS kernel)

I cant make any selection,so the device again turns off.

If i try pressing '0', this again tells me,

'Can't flash kernel,required files not found.

hit any key to panic'

Am dumbstruck!!!

Need to boot into maemo,without having to goto a desktop!!! possible????

Yeah,i tried the wiki,but its down now.. And i can just reflash the kernel+bootloader instead of reflashing firmware or rootfs!!??

I am eager to know what is the problem actually,why is my maemo kernel not shown up on the list.

Thank you flipalong.

type in
flasher-3.5 -F <firmware-image> --flash-only=kernel -f -R
into maemo flasher

but you have to have the maemo firmware image in the flasher and the n900 connected and everything.

i had the same error when i installed nitdroid and the maemo power kernel at the same time. i still dont know what the cause was

and also flashing the kernel will erase multiboot. im not sure what itll do to meego, but maemo will stay the same.

Will i have to lose the apps installed or any other data if i use this method???

if you flash just the kernel, u keep all ur apps and ur settings and everything.

if u do a normal reflash then u lose apps and lose settings but keep ur personal files (music, pics, vids etc.)
if you do a reflash and emmc reflash, u lose everything

multiboot is tied to /sbin/preinit, flashing the kernel will not remove multiboot

Code:

flasher-3.5 -k zImage -l --boot="init=/sbin/preinit_orig ubi.mtd=rootfs root=ubi0:rootfs rootfstype=ubifs rootflags=bulk_read,no_chk_data_crc rw console=ttyMTD,log console=tty0 snd-soc-rx51.hp_lim=42 snd-soc-tlv320aic3x.hp_dac_lim=6"

should override multiboot.

Or just press 0.

I dunno about the flash code you gave but pressing 0 didn't work for him (He really did something weird I guess...)

Explanation for the flasher code then;
You're loading the stock kernel image, which you can find easily on the internet, the booting it with a modified CMDLINE (kernel parameters), they're all the same actually, only init= is using the backed up preinit.

A way to get the zImage,
Download http://repository.maemo.org/pool/mae...+0m5_armel.deb
Unpack it, then unpack the .fiasco with flasher-3.5 -F .fiasco file -u
