[PRJ] Rooting the Droid Eris

Title: Rooting the Droid Eris: What else needs to be done?

So, I've looked around a lot, done some snooping, and I've hit the point where I think I need some help...

Over the last two days or so, I have been messing around a lot with the Eris.
I've been able to get fastboot as well as adb to recognize the device. Unfortunately, I can't get fastboot to do anything other than recognize it. I've tried rebooting the device through fastboot to no avail. I also believe I have a pretty much complete system dump, which I am willing to post if it is of benefit to getting things moving. The one file I don't have, that I'm not sure is needed or not, is "init.rc". Every time I try to pull it, it says "permission denied".

So, what's next? Any and all help is appreciated.

Thanks , guys,

1: this is NOT the section for the Eris
2: to dump your boot, get into recovery or system, connect via adb and:

cat /dev/mtd/mtd2 > /sdcard/boot.img (where mtd2 is your boot partition)

Seriously, this is not the Eris section, so please go post over there.

Uh. Guys. The Eris is a rebranded Hero.

To the OP, have you tried the instructions for the Sprint Hero?

...I'm about 99% sure there is not Eris section. Sorry about that.

From what I've seen around, none of the CDMA Hero methods work on the Eris. I will definitely try it tomorrow. I'm not sure if this is a justified fear, but just trying random root methods could brick my phone. I'll keep looking around and trying different things, though.

edit: So, tried pulling /dev folder. My out put says that it's "skipping special file" and then lists all the files in the folder. I can't get it to copy to my sdcard either as I get a "/sdcard/boot.img doesn't exist". Sigh. I'll keep trying. Idea: do I need my sdcard partitioned a certain way to get the file to write to the sdcard?

1) You won't be able to access mtd2 unless you're root, so you need to do that first.

2) When adwinp said to run "cat /dev/mtd/mtd2 > /sdcard/boot.img", that's being run from a shell on the phone itself, *not* from "adb pull". If you tried doing something like "adb pull /dev /sdcard", that's going to fail. You have to open a shell on the phone via adb, then copy the contents of mtd2 to a file on your sd card (i.e., /sdcard/boot.img). But again, you won't be able to do that with an unrooted phone because the mtd device files are not world-readable:

# ls -l /dev/mtd
crw-------    1 0        0         90,   4 Nov 12 03:33 mtd2

I'm not sure if this is a justified fear, but just trying random root methods could brick my phone.

The method of becoming root for the Hero (using "asroot2") will not brick your phone. It's what you do with root once you have it that could brick it.

Thank you so much. Great info. I will try the asroot thing out today.

CDMA Hero Root Method: Got through the first steps:

"./adb push asroot2 /data/local/
./adb shell chmod 0755 /data/local/asroot2
./adb shell"

Then:

"$ /data/local/asroot2 /system/bin/sh
[1] Killed /data/local/asroot2 /system/bin/sh
$"

So, that seems to be a no go.

Yea, the Sprint Hero method won't work. And the Eris is a rebranded Hero so technically this is the right section.

Okay, so if that method doesn't work, what's the next step?

edit: Would the method where we open a recovery.img on the phone and then install the superuser.apk work? I'm not sure if there is a general recovery.img that it could boot into or not. Any thoughts?

I'm hoping someone will care about this soon. From all the research, a LOT of times people are walking into VZW looking for Droid and walking out with the snazzy little Eris. It's become the phone of choice at the store.
