How to dump a recovery image?

[Guest wired]

I'm after the stock recovery image for my optus streak, there isn't one floating around unfortunately. If I can get my hands on a stock optus streak, would this be the command to extract it, in a shell?

dd if=/dev/mtd/mtd0 of=/sdcard/recovery-dump.img bs=4096

I should then be able to fastboot flash it onto my phone?

thanks!

I gave it a try, but the Streak just reboots when trying to run the re-flashed recovery. The phone currently has a working -21 recovery image. What I did was:

- run the dd command from a Terminal window on the phone, and copied the resulting 5,242,880 byte .IMG file to my computer.

- flashed clockworkmod-streak-2.5.0.1 and tested it - CWM it loads up

- flashed the .IMG file (of the previous -21 recovery) from the dd command - the streak shows a black screen for a short while then reboots, after i select the Update.pkg option.

Is the recovery at mtd0? What am i missing?

thanks!

that's how its done on other phones. i'm not sure how to dump it for the dell streak because the conventional method does not work. the other stock recoveries out there are extracted from the pkg rom i believe.

you need figure out the correct device name and partition.

Thanks for the help guys, fards last night posted a -00 recovery image that works on mine, so I don't have to do it anymore!

Just use good old cat command, like this to list all.

this is it from my nexus one;

cat /proc/mtd

mtd0: 000e0000 00020000 "misc"

mtd1: 00500000 00020000 "recovery"

mtd2: 00280000 00020000 "boot"

mtd3: 09100000 00020000 "system"

mtd4: 05f00000 00020000 "cache"

mtd5: 0c440000 00020000 "userdata"

Here is a handy link about the dd command, the syntax and how to use it: http://en.wikipedia.org/wiki/Dd_(Unix)

hopefully that might help some one
