Updated: There Are Some Issues. UnrEVOked Is Here - One Touch Root For EVO 4G And Hero, Working Even After EVO's First OTA Update!
Last Updated: July 21st, 2010

Yesterday, we reported that the EVO 4G was rooted, right in time for the launch day. The root method, however, required a full wipe and was quite tedious.

Updated: There Are Some Issues. UnrEVOked Is Here - One Touch Root For EVO 4G And Hero, Working Even After EVO's First OTA Update!

The same hour the root instructions were released, a new root method, called unrevoked, was promised and scheduled to come out by midnight. However, Sprint's OTA update fixing the SD card issue also patched up the vulnerability that both root methods used.

Fear not though, unrevoked was still released a few hours ago and works for both pre-OTA and post-OTA EVOs and only pre-OTA Heroes.

The root method is very simple - you just download the .apk from your phone's browser and install it as an application. Then (you guessed it) run it.

The new vulnerability that allowed root to be achieved has not been disclosed this time, in the interest of keeping the EVO rootable for as long as possible:

Update #1 [6/5/10 1:00AM]: I've gone ahead and applied unrEVOked to my post-OTA EVO and it had root within 5 seconds. You will find what the process looks like at the bottom of the post. To check afterwards, I've installed android-wifi-tether - the first and best app I install when I get root, and it loaded and asked to approve su permissions.

Update #2 [6/5/10 1:45PM]: I am actually having some issues with accessing root. My USB debugging is enabled and I've seen 4 su prompts, so I know *something* is working. However, these don't:

1. Android-wifi-tether doesn't actually work - it loads and starts the AP but neither my laptop nor Alex eReader can see it.

2. 'adb remount' doesn't work and fails with this error: remount failed: Operation not permitted. This means I cannot remove the stock apps I want to remove, as the file system is readonly untill 'remount' works.

3. Clockwork recovery using ROM Manager doesn't install - just comes up with a non-descriptive error, though it does detect the EVO's phone model correctly.

Update #3 [6/6/10 12:00AM]: It looks like the android-wifi-tether app indeed has an issue on the EVO - http://code.google.com/p/android-wifi-tether/issues/detail?id=362

Update #4 [6/6/10 5:19PM]: android-wifi-tether now works, thanks to an update!

I asked for confirmations and clarifications, and got them directly from the horses mouth:

So hurry up, download the app from http://www.unrevoked.com and report back with your experiences.

See you on the other side for the root!

  • Henry L

    Worked for me as well. The ROM Manager recovery isn't installing though - some error after it detects it's an EVO and I press download.

    • Q

      Same problem-- after selecting "Flash ClockworkMod Recovery" I confirmed the phone model, and it ran for a second before getting "An error occurred while flashing your recovery."

    • http://www.AndroidPolice.com Artem Russakovskii

      Same problem with me. Something is fishy.

    • Louis

      I get nothing... I get a confirmation of "done" but nothing happens after that

      • ScottJ

        Same thing. No request for superuser access, and Wireless Tether says it doesn't have root access.

        • http://www.AndroidPolice.com Artem Russakovskii

          The newest update breaks unrevoked - see this. They are promising a new version but if you want a proper root, go for Simple Root.

  • daniel

    downloaded to hero 2.1 update1
    and did not get s/r screen. root
    does not seem to work.

  • http://www.jeriwho.net/ Jeri

    which version of wifi tether did you use, sir?

    • daniel

      barnacle wifi tether

    • http://www.AndroidPolice.com Artem Russakovskii

      I used the latest available now, but didn't actually test connectivity after seeing the su screen. The tether app doesn't work for me - the AP SSID never shows up in the list on my laptop.

  • Jane

    Root seems to work well before and after I applied the OTA update.

    The android tether app seems to run normally but none of my wireless-capable computers can connect to it. I've tried every combination of settings and it still won't connect. Nothing shows up in the

    Barnacle's doesn't work for me. When i run it it shoots back an error saying "Failed to set AP_SCAN"

    Anyone else have any luck?

    • http://www.AndroidPolice.com Artem Russakovskii


      I didn't go as far as testing the connectivity at the time, but now that I've tried it, the tether SSID doesn't even show up in the WiFi list on my laptop. Together with 'adb remount' not working, I suspect something isn't complete here.

  • Palak Desai

    Does this root allow you to uninstall apps from Android or do you still have to go into recovery?

    • http://www.AndroidPolice.com Artem Russakovskii

      It's actually not working for me - I get an error, which I pinged @unrevoked about:

      adb remount
      * daemon not running. starting it now *
      * daemon started successfully *
      remount failed: Operation not permitted

  • babelfish

    The evo has bad battery lifebecase of all of thesebackround apps like stocks and friend stream keep popping up. How in gods name do you keep these apps from constantly launching even after you kill them in task manager?

    • http://www.AndroidPolice.com Artem Russakovskii

      You can't stop them from starting I don't think but what you can do is remove some of them you don't want altogether... that is, when the removal process works, as it currently doesn't (see Update #2 in the post body).

  • http://www.AndroidPolice.com Artem Russakovskii

    android-wifi-tether issue is now fixed!

  • Mhmobile

    So unrevoked can now be used to root and the tether app will function correctly?

    • http://www.AndroidPolice.com Artem Russakovskii

      That is correct.

  • TK

    works perfect, using internet from evo on my computer now. its pretty fast any other apps to get on my newly rooted phone?

  • babelfish

    So what is this deal with the ota that came out last night? Is it safe or is that Sprint trying to lock out tethering?

    • http://www.AndroidPolice.com Artem Russakovskii

      There was no OTA last night - the only OTA came out on the 4th, the same day EVO launched. That OTA is accounted for by the last part of this post's title.

      • babelfish

        Nah dude last night my evo told me there was some update available but I dealt with iphones long enough to know not to update blindly. I think it was a plr? I forget what the anogram was...

        • http://www.AndroidPolice.com Artem Russakovskii

          A PRL update is just a tower config for better reception. It has nothing to do with phone's software and can be safely performed.

        • Mhmobile

          Just checked mine, showed "System Upgrade"
          1.32.651.6 (13.14MB) FOTA update.

          Not sure if this was the 1st one that came out on the 4th? Is this one safe to install? don't want to chance losing root...


        • http://www.AndroidPolice.com Artem Russakovskii

          Yeah, that's the safe one from the 4th. You can see the version matches the one I posted there.

    • Luis

      Which one are u using in the market because i am not having any luck using my evo for tethering and i rooted already please help

  • Mhmobile

    Thanks Artem! I'll go ahead and install

  • dj scissor

    will this root reset my phone?. i have spent all weekend setting it up and installing apps. someone who has done the root please advise.

    • Adam Powell

      Also will rooting my phone void my sprint insurance...

  • Swebby

    Worked perfect and seamlessly. Just need to get that remount to work so I can remove some bloatware. Thanks so much.

  • Steve

    If I install and run this what will it do exactly?

    I think I understand that rooting my phone will give me admin access to everything on my phone so I can turn on everything in the OS that HTC and Sprint turned off. I can remove the apps that I currently can't like Sprint Nascar app. and, I can install a custom ROM.

    But Can I do all that with just this program or do I need to install something else as well? Is there a website or PDF that I should read first?

  • babelfish

    Hey so I just rooted via unrevoked can I uninstall the app when I am done, and also when I go into terminal to su root passwd to change for security I get permission denied! Wtf I am root!

  • Socalfrank

    All I want is the Wi-Fi tether, so this looks great, but before I do it:
    1. will I still get OTA updates in the future?
    2. Will this void my warranty?

    • Socalfrank

      OK< So I figured it voids my warranty, so I'm at least going to wait until my 30 day remorse period with Sprint is over before doing it. Their 3G and coverage appears to be having trouble in my area and as of now, the phone is likely going back.

      But, if I stay and UNREVOKEd, will I get OTA updates ...FROYO when it comes out?

      • http://www.AndroidPolice.com Artem Russakovskii

        Rooting doesn't prevent any updates, ever - you should be able to get them fine but that may end up unrooting you.

        • Socalfrank

          How do they know you have rooted this phone? On my Nexus One, there is a little unlocked padlock when booting up.

  • AtomicWingnut

    Just used UnRevoked and setup tethering... worked great except wouldn't accept the passwords I set up. The speed was really fast. Does the battery get super hot running this?? Why the temp monitor?

  • Shawn

    If i use unrevoked, is there a way to go back in the case of needing to have my evo worked on?

    Also will all my apps be lost that are currently on my phone?

  • Justin

    for the hero, do you have to be running 1.5???

  • hcocdr

    I am toying theis on my laptop connected to my EVO wireless and not having to pay Sprint for somethting I am already paying for. U Da Man!!!

  • aramsdell

    Worked great until the latest update. Now won't recognize it is rooted.

  • james

    Hey I have down load this unrevoked when I first got my evo it rooted my phone an also gave me the supersede app an I also installed the tether was working good then my phone had said there was an update I guess software update so I updated my phone just to be updated after it finish updated tether didn't work any more I installed it and unrevoked and superuser now when I install unrevoked it don't give me the superuser app and tether still don't work any ideas an how I can fix this problem thanks.

  • MIke

    James, I have the same problem it was working great until about 20 minutes ago when I updated the evo software. anybody out there have any ideas. I uninstalled and reinstalled both the unrevoked and wireless tether 2_0_5_pre2.apk still doesn't work. It just says "unable to start tethering please try again"

    • http://www.AndroidPolice.com Artem Russakovskii

      Guys, the newest update breaks unrevoked - see this. They are promising a new version but if you want a proper root, go for Simple Root.

  • JerryN2U

    Is it possible to just do Step 1 and that's it.. Is it required to do all three steps?

  • rich

    how can I roll back the last OTA hero update, so that I can use Unreviked?

  • Joey

    I just used revoke and when i used the tether program, the program said i needed to be rooted even though i already ran the root.

  • Polly
