error flashin boot.img

[Drew408]

I just modified my boot.img using these instructions
HOWTO: Unpack, Edit, and Re-Pack Boot Images - Android Wiki
Everything worked good using the alternative method posted in the HOWTO up to the point of flashing the image. when I use the instructions given it returns this error:

# cat /dev/zero > /dev/mtd/mtd2
cannot create /dev/mtd/mtd2: permission denied

Tried to skip this step as I read somewhere it could be and got this:

flash_image boot /sdcard/boot-new.img
error writing boot: Permission denied

Any help??

fixed the issue...not a hundred percent sure how but this is what I did.

1.)set: export PATH=$PATH:/home/andrew/android-SDK/android-sdk-linux_86/tools in my .bashrc file at the very top of the .bashrc file and saved
2.)rebooted into recovery
3.)opened adb shell (which I wasnt able to do in recovery mode before adding the PATH. I ran adb as root, and and got an error stating that no devices were found, but now that i added the PATH i can adb shell as user.)
5.)then mounted the sd card where my .img was stored and executed the orignal commands. worked perfectly.

seems like it was just an issue with setting my android-sdk tools path. which I should have already had setup when I installed it, but never found out how to permanently store the PATH of my sdk tools.
