[Android Q&A, Help & Troubleshooting] zyrill:
I'm trying to dump the boot.img in the hopes of porting CWM and, eventually, CM11 to the Lenovo B8080, better known as the Lenovo Yoga 10 HD+. But I'm at a loss how to extract the boot.img.

I've been following this guide here: http://xda-university.com/as-a-developer/porting-clockworkmod-recovery-to-a-new-device and am stuck at trying to extract my boot.img as the binary is missing. All I get is

$ dump_image boot /storage/sdcard1/boot.img
dump_image: not found

I've also tried using romdump but the binary that I found won't run on the b8080, wrong architecture.

Lastly, I tried

$ cat /proc/mtd

as recommended in this guide: http://www.addictivetips.com/mobile...es-boot-recovery-and-system-partition-images/

but that also doesn't work as there is no "/proc/mtd".

What I do have is the following output:

$ cat /proc/partitions

Does anybody know how to proceed from here? Thanks!
