Hello all


Im work with this tut.
HOWTO: Unpack, Edit, and Re-Pack Boot Images - Android Wiki


Everything is fine except for the part


flash_image boot /sdcard/image.img ---> NOT OK
error scanning partitions: No such file or directory


im trying with fastboot but command dont exist


cat /proc/mtd ----> File not exist but there is something else i found


# mount point fstype device device2
/bootloader vfat /dev/block/nanda
/env emmc /dev/block/nandb
/boot emmc /dev/block/nandc
/system ext4 /dev/block/nandd
/data ext4 /dev/block/nande
/misc emmc /dev/block/nandf
/recovery ext4 /dev/block/nandg
/cache ext4 /dev/block/nandh
/sdcard vfat /dev/block/mmcblk0p1 /dev/block/nandj


I have concluded that there is no mount_point who exist /boot nor /misc nor /env .... using emmc fsys


I try this...
After unpacking/packing ramdisk and kernel without any changes into ramdisk folder...
File size of original and recompiled image is equal 16MB but little difference in ~10b


adb push image.img /sdcard/image.img
adb shell su -c "cat /dev/null > /dev/block/nandc"
adb shell su -c "cat /sdcard/image.img > /dev/block/nandc"
adb shell su -c "sync"


Reboot device....
Device stuck up on first logo (Core 4) :(


now im tried wipe image and fill with content without unpacking/packing
adb shell su -c "cat /dev/block/nandc > /sdcard/image.img"
adb shell su -c "cat /dev/null > /dev/block/nandc"
adb shell su -c "cat /sdcard/image.img > /dev/block/nandc"
adb shell su -c "sync"


Reboot device....
Everithing OK


Is there any chance that the problem is in the process of unpacking/packing or something else i dont understand ???
