Restore stock bootloader/recovery?

Last Updated:

    Can anyone give me some insight on restoring an Eris completely back to stock? I was running 2.1 OTA rooted and I'm trying to get the stock recovery back. I rolled it back to 1.5 using the SD card method, downloaded the OTA 2.1 update but it won't install since the bootloader is S-OFF. Is there an SBF that I should use for this that gives me a total stock flash? I tried to re-root and start over but I wasn't able to get SU installed...I'm all twisted around here and could use a back to basics walk through if one exists. :confused:

    The OTA update failed not because of the bootloader, but because of the fact that the custom recovery (Amon_RA, I presume) was present. The OTA process is actually performed by the stock (HTC) recovery boot, and it is incompatible with Amon_RA custom recovery (and probably clockwork, too).

    The easiest way to accomplish what you are trying is to flash the Leak-V3 ROM, and then follow that up with an "update.zip" method using the July 2010 OTA update.

    Can someone give specific on this procedure? I want to do this as well.

    Before I begin, let me say that an incredible amount of traffic gets generated on this board (and others) due to folks who end up somehow mutilating files that they download. The cause of this mutilation is almost always "short" or "truncated" files caused by interrupted downloads or incorrect disconnecting of SD cards "mounted" by the PC. The way you can avoid this problem to begin with is to check your checksums (Thanks to scary alien for that post). Please do this to insure the files you download are the correct files, and are undamaged.

    There are a couple of files mentioned in this post:

    PB00IMG.ZIP (leak-V3): 109,946,224 bytes; md5sum 1c0b0182356242a9d673a661e7458587
    RUU...exe ("Official" RUU): 130,323,038 bytes; md5sum 74035b1685b279b1aa4f17fafdbec78b
    update.zip (July 2010): 13,437,426 bytes; md5sum 6c509776a039149c392940025a13cff9

    First, Get the Leak-V3 installed

    1) Go to this Leak V3 Announcement thread and download the file.

    2) Get it onto your SD card in the root folder, and make sure it is renamed to "PB00IMG.ZIP". (that's Zero-Zero in the middle, not "Oh-Oh").

    3) Perform the procedure shown step-by-step using pictures in the thread http://androidforums.com/all-things-root-eris/75384-visual-example-pb00img-zip-update-method.html (ignore the comments about "battery pull", and run the procedure through to completion).

    Note: Alternatively, the steps 1-3 can also be performed by using the Windows PC-based RUU utility referred to as "Official" RUU

    4) After the phone reboots for the last time, there is a good chance that it will immediately recognize that the July 2010 OTA update can be applied. If that happens, you are done. If not, complete the rest of the steps here.

    5) Download the July 2010 OTA from the link mentioned in this post.

    6) After download, move it to the root folder of your SD card and make sure it is renamed to "update.zip".

    7) Turn your phone off.

    8) Turn your phone back on by holding down the Vol-Up and End/Power buttons simultaneously. (Actually, the precise procedure is this: hold down the Vol-Up button, and continue to hold it down. Then press the End/Power button, and continue to hold BOTH buttons until the screen with three skateboarding Droids shows up - you can release the buttons at that time).

    9) You will see a screen with only an image on it - nothing else. Wait about 10 seconds, and then press the Vol-Up + End/Power buttons again as in the previous step... only this time you can release them immediately. After a couple of seconds, you will see a menu appear on the phone. Use the one that mentions "sdcard:update.zip".

    Can not use amon recovery flash. Trackball will not scroll down to wipe or flash from sd card. What else can I try?

    Read the instructions again - you do not do this from Amon's Recovery. You press Vol Down when you restart, rather than Vol Up.

    How else can you flash the leaked v3 rom without using the amon recovery? Please tell me because that would solve my problems.

    Tried the Windows RUU and I got an unknown error when it tried to restart the phone into recovery. The screen on the phone never changed.

    Again, I'll tell you to read the instructions again. It tells you to place the downloaded update file (which I belive you rename to PB00IMG.ZIP) into the root folder of your SD card. Then you restart the phone to the bootloader - not to Recovery - by holding Vol Down while you press Power. Follow the instructions above (plus in the link in EU1's post.)

    In the other thread I gave you a link to a procedure that you can use to use ADB to copy some files, change the permissions on one of them, which will then allow you to run the RUU.

    Your choice. In both cases, I encourage you to read carefully. Open the posts, print them if you must, and follow the instructions carefully.

    +1 (yet again) to doogald and to erisuser1.

    The 2.1 v3 leak PB00IMG.zip mentioned above will replace the custom (Amon_RA) recovery (and the radio, bootloader, and the O/S, etc.) on your phone when you flash it. This is what puts you back to stock 2.1.

    Then, the July OTA update.zip file will apply the latest update to your phone. If you are just looking to un-root and return the phone to VZW, they probably won't care that you don't have the OTA update, so you might be able to skip this step.

    Additionally, the above procedure should not require you to use your trackball.

    Hope that helps and good luck.
