Root Easy instructions to unroot back to 100% stock?

[OUScooby]

OK, here goes nothing...

 

[OUScooby]

Why not just try it out? It won't hurt anything. Do a Nandroid backup first, just in case. Then after the RUU is finished installing, try to reboot your phone into recovery mode (vol+ + power). It shouldn't be there. Then use the adb shell tool in the Android SDK, and type the command "su" to see if you get root access. If all goes as planned, you shouldn't be able to. Also your phone should be completely stock. Verizon won't know

And, if none of that even works (which is not likely... I'm sure it will be fine...), you can always just restore your Nandroid and you'll be right back where you are at this very moment, then you can just try something else.

It will take you 15 minutes, instead of waiting hours for an answer here

Before I start, which method are you suggesting I try?

This one:

which from what I can tell is something almost identical to official OTA - and which sounds like can't be undone once preformed

or this one:

which I don't know what I'm supposed to do with the mr2 update - does it go in the sdk tools folder? then what?

sorry for my impatience, but I need a working phone for work, I need this done tonight so I can go to verizon first thing in the morning.

Sorry to burst your bubble, but you might not get a replacement Eris tomorrow morning. Many stores don't even carry them anymore. So they might have to send it with overnight shipping.

Well then I'll just have to persuade them into giving me an upgrade.

It shouldn't hurt to try and do the RUU first to see if it works. The RUU is an excecutable file from the PC. Connect your phone to the pc and then run the RUU. If that doesn't work then follow the instructions from jcase then you can successfully run the RUU.

 

[DDustiNN]

Try the RUU .exe method - it looks the easiest.

ANY method can be undone now. There are new root methods that work on any version (leak, OTA, hboot 1.49... all of 'em), so don't worry about that.

If Verizon doesn't have one in-store, they'll probably have to mail you one (takes 2 business days). Some people have also had luck switching to the Droid or Incredible, but that seems to be hit or miss.

 

[OUScooby]

So I tried this method: http://androidforums.com/htc-droid-eris/92096-verizons-ruu-official-2-1-droid-eris.html
It didn't work, the computer can't even recognize my phone. USB debuging is on it's set to charge only.

That leaves me with this method: HowTo: Flash Any Ruu - xda-developers
Now can someone please explain to me what am I supposed to do with this mr2 update file?

As I stated above the mr2 is an ruu just like the link above. They are .exe files that you execute while your phone is plugged into the pc, although I'm not sure if you should have usb debugging on.

Both of those require you to be connected to your computer in the same way. You might need to install an Android USB driver. I had quite a time finding that solution, but after that I've had no problems.

How did you root in the first place?

 

[OUScooby]

I ran the mr2 executable file - i thought this was supposed to be used somehow with this method: HowTo: Flash Any Ruu - xda-developers
anyway, it couldn't see my phone either.

To be honest I don't really remember what I did to root, I followed the instructions in the 1.5 to 2.1 thread. I had the phone connected via usb with no problems them, no I can't get the computer to see the phone, I've tried, charge only, htc sync, disk drive all with and without usb debugging on and off.

 

[Papadroid]

Try installing htc sync from HTC and see if your phone connects properly. This should install the drivers you need.


Were you able to follow the steps from here? http://forum.xda-developers.com/showthread.php?t=726885 if so then you have the correct drivers.

 

[OUScooby]

OK, they latest brick wall I've hit is that my computer just can't see my phone. I've tried on two different computers, one using window 7 starter, the other using windows xp, and I've tried multiple usb cables. I've tried powering on/off both the computer and the phone. Nothing!

I've reinstalled htc sync, and android sdk, I even did a factory reset. no luck!

 

[OUScooby]

So if I take my phone like it is, rooted, how likely do you think it will be that verizon will notice?

 

[OUScooby]

I just noticed that i no longer have wireless tether, or SU app after doing a factory reset. Could I have somehow accidentally unrooted?

Turn off your phone, then turn it back on by holding vol-up + power. Do you get the Recovery mode? And when your phone is on, does everything look completely stock as if you just bought it? If so, and no Recovery, then it's not likely they'll even notice.

 

[OUScooby]

When I try to do recovery mode, it boots up with a exclamation point and an android robot on the screen. It's been that way since my last attempt to unroot, awhile back.
It looks completely stock as I just did a factory reset. I guess I'll take it to verizon and see what happens.

 

[surgeon0214]

Do what you did to root, backwards. Make sure its exact or it won't work

I can't do that as my phone and computer wont communicate with each other.

I was 150% joking.

 

[rick311]

damn. i am hoping for an answer to this as i would like to unroot also.

 

[OUScooby]

First off, thank you to everyone who tried to help with my problem. I guess there was a (hardware?) problem with the usb connection on the phone, so I was never able to get it to connect to the computer to try any of these methods. But my thanks go out to all of you anyway.

So I took my rooted phone to Verizon. They didn't look at what software was on, and gave me a replacement eris. I tried to complain my was to an upgrade, but to no avail. I plugged the new phone into my computer when I go home, and it connected right away like it should, so I guess the problem was with my old phone, and not with drivers or anything like that.
Still I'm glad to have a working phone again, and I think I'll leave this one alone, although I will miss the wireless tether.

I still think there should be a clearly written idiots guide to unroot, it seem like something a few people are looking for, and we are not all as technologically savy as many users on here, so wading through the discussion in other unroot threads can be hard to follow.
The instruction in the all things root thread never worked for me. And of the two methods here, obviously I was never able to try either as my phone wouldn't connect to my computer, but I still have a few question left that may help future people looking at this thread.

Method 1:
This method seemed pretty straight forward, just download the program run it with your phone connected to your computer, and it will do it for you.
http://androidforums.com/htc-droid-eris/92096-verizons-ruu-official-2-1-droid-eris.html
But I never really got an answer as to what exactly this was. Is it truely 100% stock, or something very close that it is almost identical, or is it leak v3?

Method 2:
The other method suggested: HowTo: Flash Any Ruu - xda-developers
seemed to have three files associated with it; misc.img.zip, flash_image, and mr2 update. Misc.img.zip and flash_image go in the tools folder of the SDK. What is done with the mr2 update? Does it also go in the tools folder? Does it go on the SD card in the phone? Or is it not even used in this method, and it's its own method all together?

I am no longer in need of unrooting as I've got my phone replaced with a stock one, but these were the questions that I never felt I got a clear answer to. I started this thread because I was looking for an idiot's guide to unroot. Re-read the first post, remember to word your answers as if they are for that slow 8 year old kid who picks his nose and eats paste. Hopefully it will be easier for the next person who reads this thread.

 

[Papadroid]

When I have an opportunity I'm going to do this myself and do a complete write up. And FYI an RUU is official 100% stock. I'm glad to hear you were able to get a replacement.
