How to manually install Android 2.2 on the HTC EVO 4G

Sprint delivered on their promise to release Android 2.2 to a select group of testers today with a broad roll out is scheduled for Tuesday August 2nd. You can wait through the weekend to automatically receive the update or you can spend a few minutes of your time and manually install it now.

HTC has posted the file needed to update to Android 2.2 and it can be easily installed in a few simple steps. All you have to do is download the file from HTC, rename it update.zip, and flash it. Feel free to use your PC to download and rename the file or you can perform all these tasks on your phone using an app like Linda File manager.

Keep in mind this update is intended for stock phones that are running an unmodified version of the operating system. If you have previously hacked or rooted your EVO, then you should not install this update.

This update file comes directly from HTC so there is a chance that the file which comes from Sprint could be different.

UPDATE: HTC has removed the file, so either wait for the download link from Google or hit up the source link for a mirror. HTC also tweeted that this was not the final version so install at your own risk.

Follow these steps to install Android 2.2 on the Sprint HTC EVO 4G:

  1. Download the Android 2.2 firmware from HTC: http://liveimage.htc.com/OTA_Supersonic_3.26.651.3-1.47.651.1_releaseu2cqjc2e98n4o6xn.zip
  2. Rename the file to update.zip and place it on your SD card.
  3. Power off your phone then restart it while holding VOLUME DOWN and hit POWER.
  4. Wait for fastboot to load (screen with skating Androids). Use the VOLUME DOWN key to navigate the menu to RECOVERY and select it by pressing POWER.
  5. When you see the “/!” symbol, press the VOLUME UP and POWER button at the same time to display the options. You should be presented with a menu and one of the options should be “Apply sdcard:update.zip”.
  6. Use the VOLUME DOWN to navigate to “apply sdcard:update.zip” and select it.
  7. Wait 10-15 minutes for the update to install and then reboot your phone when prompted.

I was able to complete the entire process in about 15 minutes and ran into no problems. Look for a video later tonight if you want to watch the entire process before proceeding.

    Just got it installed on Angie’s EVO with no problems.

    • http://clarklab.net Clark Wimberly

      I take that back, one problem: when the HTC wizard was running on first boot it force closed right at the end and I had to reboot the phone. Everything seemed fine when it came back up.

      • http://www.youtube.com/emogamer Christopher Chavez

        I remember a few ROMs that used to do that. I was no biggie though. Everything worked fine after a reboot.

        I actually flashed the ROOTED version of the OTA that was “leaked” and everything is working perfect! Got a few strange artifacts when recording video but other than that…. its awesome!

        I’m loving all these little updates. Who woulda guessed Sprint would be the first to bring it OTA.. =D

        • http://Website jeffn

          Chris, I recently flashed the Fresh 2.1 rom per your excellent video, and was trying to install (i just realized) this new 2.2, and it would flash….I then read that it won’t work on the custom roms…do you know how i can get the rooted version of 2.2 so that i don’t have to go back and install the stock sprint 2.1 rom? any help would be greatly apprecaited!! thnx much

          • http://www.youtube.com/emogamer Christopher Chavez

            All you will have to do is flash this bad boy…

            Its COMPLETELY the stock 2.2 OTA (3.26.651.3) that was leaked on Friday from HTC. The only difference is this one has root inside. =)

            Hopefully as soon as the NEW one from Sprint drops the guys at XDA will quickly root it as well so we can have the most recent up to date stock 2.2 OTA =p

        • http://twitter.com/doublelama doublelama

          Any idea of the status of hot spot tethering with the rooted version?

          • http://www.youtube.com/emogamer Christopher Chavez

            On any rooted ROM you can always use an app called Wireless Tether for Root Users and be able to tether that way…
            As far as the Wireless Hotspot app/feature from Sprint/HTC. That will charge you to use it =p

  • geniusdog254

    HTC has now pulled the update. Link = dead :(

    • geniusdog254

      Ah crap. Updated as I posted that. Me = stupid :(

    • http://androidandme.com Taylor Wimberly

      Yeah it’s down but there are mirrors over at XDA-developers if you really want it. I chose not to post the links and will wait till we have the next official one from Google/Sprint.

  • http://Website Kuraiba

    Can’t wait to install it on my HTC Desire tomorow. :D
    By the way, what is the Quadrant score ? And the performance of the device in general ?

    • http://androidandme.com Taylor Wimberly

      Quadrant scores are comparable to the Nexus One on Android 2.2. Desire should be the same.

    • http://Website Bob Bobbity

      Running Quadrant Standard’s Full Benchmark test, 1298! :D

    Looks like the Android Market doesn’t work with this yet.

    • http://www.youtube.com/emogamer Christopher Chavez

      The Market works its just gonna take some time for it to realize Android 2.2 for the Evo is out. =/

  • http://Website Nam

    If I do this, everything off my phone will be wiped off? Could someone answer that please :)

    • http://androidandme.com Taylor Wimberly

      It does not wipe your phone. If you are concerned, just wait for the automatic update in a couple of days.

      • http://Website Nam

        I just did all the steps and it’s giving me error when I apply sdcard:update.zip

        Error msg – E:failed to open /sdcard/update.zip (No suck file or directory)
        E: signature verification failed
        Installation aborted

        What do you think it could be?

        • http://androidandme.com Taylor Wimberly

          You didn’t name the file update.zip or it’s not located in the main directory of your SD card.

          • http://Website Carlos Roman

            What is the main directory of the Sd card? CAN you copy and paste the directory as you see it on your computer to be clear on that?

        • http://Website Em0j

          If you have the file still. Just rightclick rename to “update” don’t put the .zip cause it’s already a .zip file. Then follow the directions given.

          That happened to me at first…the failed attempt. But it seems to be loading for me now. I can’t wait to see my new phone!

          Good luck everyone. Happy OTA for the EVO users!

          • http://Website Carlos Roman

            EUREKA! u were right.

        • http://Website fort

          IF update.zip doesn’t work then change the name to update one or the other should work.

    • http://Website Tonyheat

    Everything works great so far, very fast. High 30s Linpack. I did lose root and market not showing any of my downloaded apps. Wonder if sprint is gonna push another 2.2 update next week to my phone.

  • jakmayhopher

    when will us myTouch users get the damn 2.2 update! FRAK T-mobile!!! :( i might as well just get the Vibrant.

  • http://Website CJ

    I’m sure you’ve all heard by now that HTC officially announced on their Twitter page that this isn’t the final ROM and that installing it will most likely cause issues with your phone? Head to Twitter and read their page for the original and subsequent posts on the matter.

  • robbnice

    Hey Chris
    I just saw your YouTube video on using Rom Manager as a better way of rooting a Rom for your HTC EVO, I saw that you used a item in the video that I didn’t have, it was call Netarchy, is it something you mush have or is there a way to get Netarchy and use as part of the same process in your YouTube video title “SUPER EASY backup,Flash and Restore’ I will be waiting for your reply, don’t leave me hanging bro!

    P.S. your YouTube videos are the greatest, it make a regular guy like me feel like I can try and do new things out of my comfort zone, great info, thank you for giving a dude like me a little courage from a technical stand point.
