[Desire Q&A, Help & Troubleshooting] rain5:
Hi,

I'm trying to roll my own boot image to install on my rooted htc desire running TMOD/froyo 2.2, I used the guide "HOWTO: Unpack, Edit, and Re-Pack Boot Images" at android-dls.com using the correct base address ( 0x20000000 ) passed to mkbootimg. This all goes fine but every time i try flash the image i just rolled i get this;

sh-3.2# flash_image boot boot-new-2.img

Side note: flashing the extract of /dev/block/mtd2 back to mtd2 works perfectly, i just dont understand.
