    Ok so I know there are many threads on this already, and I apologize for creating yet another one, but I can't seem to find a clear answer on how to do this. I've already tried the method described in the "Guide from stock 1.5 to the latest root 2.1 thread" and that method failed.

    Here is the situation, I'm having an issue with my phone that is basically making it unusable, see this thread: http://androidforums.com/htc-droid-eris/126553-phone-stuck-headset-mode.html#post1180472
    This is my 2nd eris after having it replaced once already, and I'm going to try and use this problem as an excuse to complain my way to an upgrade. But before I go into Verizon I need to unroot my phone. I currently have a rooted v of 2.1, I'm not sure what is is called but I think it's basically a rooted version of the official OTA. I AM NOT LEAKED.
    Now after the OTA I don't know if 100% stock means 1.5 or 2.1 but basically I need it so Verizon can't see that I've voided my warrenty.

    I am looking for an idiots guide to going back to 100% stock. I've found a few threads on this but I am not tech savy enough to understand the technically discussion to know if these methods will even work for me.

    I'm looking for a easy to follow guide back to stock that is written so that even an 8 year old can follow it. And I'm not talking about one of those freaky computer genius 8 year old, I'm talking about the kind of 8 year old that picks his nose and eats paste, the one who is a little bit slow. You know who I'm talking about we all went to school with at least one kid like that.

    Many thanks.

    mr2 is an ruu (Rom upgrade utility). The mr2 was the OTA sent out in April, the only difference being that this will reflash the whole phone. This will restore your phone to complete stock. Once you flash this they will not be able to tell you had the phone rooted.

    FYI,

    You can still download the MR2 RUU from PCD phones (HTC's distributor) at this link:

    Personal Communications Devices | Our Devices - ADR6200VW

    (look over on the upper right hand side of the page) for "MR2 Upgrade"


    Please report back if it succeeds or fails, or whether you had to use Jcase's instructions to make the phone accept the RUU.

    OK I'm lost again. I've downloaded the mr2 update, and I donloaded both files linked on the xda thread misc.img.zip and flash_image, but the xda thread has no instruction on what exactly to do with them.

    I'm assuming that since your phone is rooted you have the sdk installed. Place the flash image and the misc image in your tools folder and then follow these instructions using command prompt:



    adb shell push flash_image /data/local/flash_image
    adb shell push misc.img /data/local/misc.img
    adb shell chmod 777 /data/local/flash_image
    adb shell /data/local/flash_image misc misc.img

    I'm pretty certain that it will not work unless you use jcase's instructions. I believe many have tried to use the mr2 in the past to unroot and were unsuccessful.

    OK but I'm about to try this. Do I put mr2 update in the tools folder also? Then what do I do with it? or will that be clear once I start the process?

    I saw that thread but that seemed like it was for leak users. I wasn't sure if that would work for me.

    the above mentioned exe install is the easiest you just run the file while your phone is plugged in, it does the rest (RUU_Desire_C_Verizon_WWE_2.36.605.1_release_signed_with_driver.exe)
    Basically plug in your phone, run the file RUUetc...etc...exe and read PC instructions it will do everything you just hit next, next, next, and your done. wipes everything off the phone.


    I believe you can also just download the NEWEST OTA for Eris 2.1 that just came out officially July 18th:

    http://android.clients.google.com/p...Verizon_WWE_2.37.605.4_2.36.605.1_release.zip

    1. Download file & rename it update.zip
    2. Place file on the SD card (NOT in any folder) then shut off your phone
    3. Hold down Volume Down & Power
    4. Select Recovery and press the power button
    5. The phone should reboot & give you a screen with an exclamation point
    6. Hold down Volume Up & press the power button
    7. Select Apply sdcard:update.zip long wait time and your done.

    Papadroid's instructions seem like they will work, I just need a little help walking me through the process. What do I do with the mr2 update? do I put it in the tools folder in the sdk installer? then what do I do with it? or will that become obvious once I start the process.
    I want to make sure I know what I'm doing before starting the process, i don't want to brick my phone because of a simple error on my part.

    That is exactly why I said

    Probably vague wording for the OP, I'll admit.

    There was a prior report 6 weeks ago or so from a user "BlazEd ONe" that he could use the MR2 RUU on a rooted phone. I never tried the RUU, but the MR2-derived "PB00IMG.ZIP" file would definitely NOT work on my (rooted) phone.

    Correct.

    Largely incorrect - it won't work without a stock recovery partition, and also won't work for the vast majority of dev ROMs even if a stock recovery partition was in place.

    The current OTA (July 2010) is only for patching Leak-V3 = OTA-2.1.

    It would work with the PlainJane ROM, but not with Ivanmmj Official 1.0 (Ivan zipaligned the apks, so their sigs no longer match what the patcher expects to see), or Amon_RA recovery - the rooter would have to temporarily put the stock recovery boot back in place to get it to work.

    The above mentioned exe being this? http://androidforums.com/htc-droid-eris/92096-verizons-ruu-official-2-1-droid-eris.html

    I saw that thread and it was a little unclear. At first it seemed like it was for leak users, then after reading it again it seemed like it was to upgrade to v3 leak.
    Can some one confirm that this method will;
    1.) return me to 100% stock, not some other leak version.
    2.) work on a rooted (not leaked) phone
    3.) remove all trace of rooting

    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 ;)
