Hi, i have flashed 3 images on my rooted desire:

- the original backed up image
- splitted & recreated boot image with the same kernel and initrd as the original boot img
- boot image extracted from update-cm-6.0.0-N1-RC3-signed

Only the first image boots up, the other 2 do not even start on adb logcat. I have to reflash the original to boot up. This is what I do in recovery:

# ./split_bootimg.pl  boot.img
# mkbootimg  --kernel boot.img-kernel --ramdisk boot.img-ramdisk.gz --cmdline 'no_console_suspend=1' -o newboot.img
# adb push newboot.img /sdcard
# cat /dev/zero > /dev/mtd/mtd2
# flash_image boot /sdcard/newboot.img

this does not boot up. If I flash the original boot.img however, it goes up.

One other thing: there are some notices when flashing, but as the original boot.img shows these also and it boots up, I presume they are not that important.

This is reported as not an issue here URL.
I also have tried to chmod to 777 the mtd0.

but when I reboot, the Fastboot version has not changed and the boot image is still the same !!!!
I'll keep doing some investigation but any advice is welcomed
