Recovery Partition Backup - Permission Denied

[AVanover5]

I'm having an issue backing up the recovery partition. I use the "ConnectBot" app for a local unix shell. I mounted the root directory as r/w first because by default it's r/o. Then I tried backing up the recovery partition like this:

$ cat /dev/mtd/mtd1 > /sdcard/mtd1.img

But I got a permission denied error. My phone is already rooted. So what am I missing here?

I may be wrong, but I believe the internal storage (at least, certain parts of it) are mounted as RO when the phone boots. You may need to explicitly mount the dev/mtd folder as rw, perform the command, then you should remount it as RO again to prevent unwanted things from happening in there.

You're right, certain parts are read-only. That's why I set the main directory to read/write (using RootExplorer because it's quicker than typing, not from shell). Otherwise, I'd get a permission denied error. I guess I'll check every subdirectory from root to mtd just to be sure...

UPDATE: Yeah, all directories are r/w. Thanks for your help anyways though Taegost. I greatly appreciate any help.

I ran this and got the following output:

$ chdir /dev/mtd
$ ls -l mtd1
crw------- root		root		90,	2 2010-12-30 02:13 mtd1
$ █

The dashes are split into three parts; the user, group, and others each of which have (r)ead, (w)rite, and/or e(x)ecute. So, am I not the owner? o.O I'm logged in as root right? It says root owns it. I'm so confused... I'll try chmod...

UPDATE: "chmod 606" mtd1 responds with operation not permitted.

All I had to do was login to super user with "su". I realized it when my shell was "$" and not "#". I feel so stupid right now -.- I must just be tired. No chmod needed. Wow, lmao...
