Why does OTA update 3.70 keep failing?

Last Updated:

  1. I have an HTC EVO 4G That i rooted using the unrevoked method. When I try to update the htc software to the 3.70 FOTA update, it downloads and begins to install but after the reboot and beginning of the install it gives me an exclamation point inside a triangle next to the android guy and does nothing else even after waiting hours. Thinking this was root related i restored my phone to defaults (wiped it out) in recovery mode and tried the update again with the same results. Is this a root related issue and how can i make the update work?

    1) Never accept an OTA update while rooted
    1) Never accept an OTA update while rooted
    1) Never accept an OTA update while rooted
    2) It's a good thing it's not working. If it did, you'd lose root and have a hell of a time getting things to work correctly again.
    3) Wiping data in recovery does not unroot your device. All it does is take whatever rom you are running (or stock) back to stock with all data wiped out. It does not remove root.
    4) You *can* install the OTA update if you follow the correct procedure to unroot first, but this is a bad idea if you want to keep root. Rerooting with the new 2.10 hboot is not easy.

    If you want everything you need out of the new OTA, flash a rooted version of it as you would any other rom. Here are a couple you can flash:

    [ROM] RUU SuperSonic EvO 3.70.651.1 OTA - Stock - Sense - Deodexed & Odexed Version - xda-developers
    ♠♠♠[SteelROM RevI.2]♠♠♠ UPDATED 12/19 v3.70.651.1 │Rooted│ DeOdexed - xda-developers

    You also need to update your radios, etc. found here:

    [ Radios ][ 12-17 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions - xda-developers

    If you aren't sure how to do this, follow the instructions found here:


    Always make a nandroid backup before doing any of the above. Keep in mind that this will not update your hboot as the OTA would have. There is never a good reason to update hboot, and will be more of a pain to deal with than anything else.

    Ok.. I have to chime in here.

    I keep hearing the whole "never accept OTA" talk over and over again. I completely accept the fact that it will make you lose root. Is that the ONLY reason you shouldn't accept the OTA?

    I have have been using unrevoked since version 1 and have accepted EVERY single OTA since Launch. Yes I lost root, but I have NEVER had to do a full install or my apps (from backups or otherwise) or resynced by contacts or anything like that. I just had to deal with waiting for unrevoked to catch up.

    And yes, I will only use unrevoked. I have flashed roms in the past, but hate having to deal with the "Flash your radios, flash a kernal...etc" bs. It simply isn't worth it to me. I appreciate others are willing to put up with what I consider to be a hassle.

    I root for two reason... Remove bloatware and Wifi Tether. Unrevoked gives me all that and I don't have to Wipe my phone. In fact, I have NEVER had to wipe my phone since I first got it (with the exception of flashing custom roms, but did a nandroid backup of my unrevoked os). And would hate to have to do it by having to flash a rom just to get root.

    So I accept the OTA knowing I will loose root, but the unrevoked team is so damn good that I rarely have to wait more than a month. Totally worth it to me.

    To the original poster, If you are willing to loose root for a bit, I would be more than happy to walk you through the steps to upgrade to the latest OTA and you won't have to wipe your phone.

    I'm rooted on the OTA ... To get it done, I had to:
    1) put the original recover on
    2) OTA (actually a couple of times since I also back-rev'd the OS)
    3) flash a custom recovery
    4) flash root

    I agree with all the above, although I've had to wipe my phone once to get root, given the instructions I had to root 2.2 after getting there using the leaked version.

    The trick is to make sure you have a stock recovery and all the Sprint apps are installed (that last got me for a bit). If you have s-off (which you should if you've done unrevoked forever), then, once the OTA is loaded, you can flash a custom recovery and then flash the superuser app, like the next post by bzxzlg says.

    I have lots of history, saved web site passwords, etc. that I don't want to lose. So, being able to do the OTA update without a wipe of my data was the best choice for me. I think the phone is running better with it, too.

    if you use the stock rooted roms and install from recovery you ONLY have to wipe cache and dalvik cache, YOU WILL KEEP ROOT AND ALL DATA, the wait time for the release of unrevoked is getting longer and longer and there is ALWAYS a chance all paths to root will be locked, so its your choice but not difficult to update without otas

    You guys are right in that it is possible. That doesn't change the fact that it's a very bad idea. You put your phone in a weird state by upgrading to an hboot that was most likely created to avoid root. In the case of 2.10 (and I think 2.02), you can't even use the same recovery images. Not only that, but once you get to hboot 2.02 or 2.10, you can never downgrade your hboot, which didn't used to be the case. There is never a good reason to accept an OTA if you want root. Period. Flashing a custom rooted rom, then the radios is much easier. I can't tell you what to do, so do whatever you like, but if any of you ever end up with a brick or a half-rooted phone, don't blame me. Trust me, a majority of people who have been rooting their phones for a lot longer than me will agree.

    What's the trick to restoring a functional phone (rooted or otherwise) after the 3.70 OTA on an unrevoked-rooted EVO?

    It seems more than a few people with rooted EVOs have taken the OTA (by mistake or otherwise) and are now stuck.

    Ok my 2 cents on OTA and how I've dealt with it in the past:

    1) Check xda if a hack exists for the OTA
    1a) Yes: Run OTA, re-root if needed
    1b) No: Hold off rooting


    The only issue now is getting it to install...
