[PRJ] Rooting the Droid Eris

[Videofolife13]

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?

 

[Videofolife13]

...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.

 

[Videofolife13]

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.

 

[Videofolife13]

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.

Are we able to use this exploit at all?

 

[binny1007]

I dont know why more people are not trying to get this rooted, because as soon as sprint releases a update the hole will most likely be pached for them also. So it would make sence to root this ahead of time. Thats just my 2 cents.

The hole has already been patched. The FW on the Eris is patched as well.

i know the eris is patched as i have one, but the hero FW still has the unpatched exploit. what i was saying was it would make sence for the eris to get a root exploit so that way when sprint updates thier FW it will be easy to root the hero. making everybodys life a little easier

 

[davidboyd]

Take it to a Droid Eris board. This is the CDMA Hero board. No one here cares.

It would make it easier...but the motivation is still harder since we can still always get back there if needed (downgrade to vulnerable firmware with RUU.exe and root, then upload a custom ROM that doesn't update from Sprint )

I'm sure a new root will show up for you guys...Video is on the right track, post those exploits (and perhaps alert Amon_RA of them?) and one of them will be bound to work (constant of life...new exploits will be found )

davidboyd: the eris *is* a CDMA Hero...

 

[davidboyd]

No, the Droid Eris *ISN'T* the same as the CDMA Hero. If it were the same, you wouldn't be asking how to root the Eris since the steps to root the Hero are all over this forum.

The Eris is similiar to the Hero, but not the same. Take your Eris noise to an Eris forum.

Dude people need to calm down. Technically the eris is the hero but for VZW. When we wanted our hero rooted we asked everybody. It's not like they are spamming the forum, its just a thread. Like i said before you Eris guys should wait for the moto droid to get rooted, asyou all could probably use the same exploit. Just have patience. It took over a momth for thehwro to get rooted

 

[DroidHead]

Not to add to the BS that some are comming in here with... The Eris is not a Hero, it is the HTC Desire rebranded as the "Verizon HTC Droid Eris"...

Anyway, Where is the Eris forum?

Ok buddy this a community to help, if you dont have anything productive to say dont say it, and do your research first. Many times when a phone is released on differant carriers they will rebrand it, such is the case with vzw and sprint, different names do not mean different phones, look at the wiki and you will see. take the touch pro, same phone but it is a little different from carrier to carrier.

No, the Droid Eris *ISN'T* the same as the CDMA Hero. If it were the same, you wouldn't be asking how to root the Eris since the steps to root the Hero are all over this forum.

http://pdadb.net/index.php?m=pdacomparer&id1=2080&id2=2005 look here pretty much the same phone.... if there was a ERIS forum do you really think that we would be posting here(use some common sense buddy).... I guess in a few weeks when sprint updates there FW and you loose your root you will be in the same boat as us. Like i said if you cant help than dont post.

Not to add to the BS that some are comming in here with... The Eris is not a Hero, it is the HTC Desire rebranded as the "Verizon HTC Droid Eris"...

again look here the only differance is a little better CPU.... http://pdadb.net/index.php?m=pdacomparer&id1=2080&id2=2005

I agree that once the moto gets rooted than we should get root to, but from what i have been reading it looks like they are looking into a bootloader exploit, witch would not help us at all, witch is why threads like this will help to bring people in that have the know how on rooting.

So back on topic.....
