Well, well, well, what do we have here? Why, it's the Android 3.1 update for the ASUS Transformer that we were all expecting early next week. The 220MB package conveniently showed up on the web earlier this morning, bringing joy to Transformer owners who are reporting successful updates without any issues.

The Android 3.1 update to Honeycomb brings performance fixes, an enhanced app switcher, resizable widgets, and alleged improvements to the keyboard dock.

Grab the download file from our mirror here (I've already untarred the original .tar file so you don't have to) and then proceed to the slightly tweaked instructions below:

Note: You will likely lose root if you're already rooted, as this is a stock update.

And, of course, we do not take responsibility for anything that may happen to your device. Proceed at your own risk.

  1. Place EP101_SDUPDATE.zip that you just downloaded on your SD card
  2. Make sure the Transformer is plugged in or has at least a 50% battery charge.
  3. Power off
  4. Press the volume down key and power key at the same time and continue to depress both until you notice a ROM Boot screen that advises you to press the volume up key within 5 seconds to start the ROM update process.
  5. Press the volume up key and the unit will update and reboot. It should take about 3~5 minutes
  6. After a reboot, a user notification should arrive in five minutes or so that the docking station has a firmware update available to version 0209. Please follow the instructions and update the docking station and then complete another reboot. The 0209 firmware offers improved typing speeds, mouse tracking and USB compatibility.

If you decide to flash the update, do let us know how it's worked out for you or if instructions need any more tweaking.

Rooted users may want to check out this xda thread where a pre-rooted update was posted.

    You cant flash this via clockwork recovery. You need to have the stock recovery. Since most of the rooting instructions for the Transformer involves replacing the recovery sytem, this cant be applied on a rooted Transformer.

  • Christo Acosta

    You rock, just saying.

    I'm not ready to take the plunge into the root-less unknown, but still...

  • Graham Gibby

    I've been trying to root my TF101 all day, and not a single downloaded file worked, and a coworker asked "How do you know?" Because of the exclamation point in the yellow triangle, maybe?
    I did this, now shows

    Android version 3.1,
    Build HMJ37.US_epad-
    If it sets back my rooting, so be it.

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

      Excellent - is everything working OK there? Notice what those supposed improvements in the dock are?

  • MicroNix

    Sweet. Been impressed with this tablet so far for the price. I *do* hope it fixes some of the FCs which appear to be honeycomb related.

  • AndroidUK

    Worked fine after I accidentally allowed a memory wipe by not reading the screen properly! - Fortunately, Transformer restored apps automatically from Google

  • http://talk3g.co.uk Hands0n

    Job done. A piece of cake. Happily on 3.1.

    The only "interesting" bit was getting the file across to the Eee Pad Transformer from my Mac. It is supposed to show up in Finder as an external drive automatically but does not. The Pad is looking for Asus Sync (only available for Windows PCs). So I had to copy it on to a removable SD card, insert the card into the Pad, copy the file from the removable SD card to the internal SD card memory. Then I could carry on with the instructions above to update to 3.1.

      All honeycomb devices use MTP rather than USB drive mode because it solves the problem of locking out the SDcard from apps while mounting it. The problem is that MTP is used by _many_ devices that compete with the iPod so Apple don't include the protocol in osX. Google have written a Mac app to provide MTP support here: http://www.android.com/filetransfer/

  • ben dover

    Just flashed it. So far so good!

  • colby

    Works exactly as described. Got my Transformer on Friday. Glad to see 3.1 is here already. Keyboard dock should be delivered on the 31st!

    • ben dover

      I got mine yesterday as well! Excited about getting the update only 24 hours later! :-)

  • Sibuna

    Went flawlessly here. Used my phones SD card

  • loretta tay

    updated to 3.1 fm tw to us ver but till now no notificattion to update dock

  • cosmic

    Asus seems to be the best bet for an android tablet at the moment. Great price, great screen, great accessory(dock), quick updates. Not to mention the extra codecs and functional sd card slot they threw in. Acer isn't half bad either.

    (Hm all the PC makers seem to be doing really well in the tablet market. Something about not being fat with wireless subsidies I guess.)

  • colby

    Actually I'm not seeing the video / movie rental app. Not sure what I am missing.

    • loretta tay

      mine also dun have

  • Tyler

    Does not work for me. It starts loading the at the Android update screen that it shows a (!) ,stops, reboots and receive a notification that says its been updated. A very few amount of people seam to be having this problem. Im running stock btw

    • loretta tay

      which sku r u having?

      • Tyler

        sku as in country? im in the US got mine 4 days ago. It seams a few people in XDA are having the same exact problem

        • NCX

          put the file at location. /removable/SD card or it won't work

  • http://www.kuwaitiful.com Obeya

    I was hoping the update would solve the "this item is not available in your country" issue. Which is a fault by Google, since the apps I'm trying to download are free.

    But that didn't fix it.

    • loretta tay

      what app u downloading

      • http://www.kuwaitiful.com Obeya

        Pretty much anything.. Angry birds.. Flash.. Worms.

  • PaperApe

    anyone know if the 3.1 update fixes the laggy flash content when it's displaying 720p or 1080p videos????

    • Tyler

      YES IT DOES!!! Its like a complete system over-hall. it even shows a data transfer animation on the wifi indicator. Everything is quicker and responsive even multi tasking!

  • NCX

    move the downloaded file to the location:
    /removable/SD card

    make sure you place the file in the ROOT of this location or it will not see the update

    don't use the /sdcard or the update will stop on the android recovery screen forcing you to hold power until it turns off

    • Tyler

      I couldnt answer above but a poster in XDA was having the same problem as me.. he figured out that its downloading and becoming corrupt on (TF and PC) . He used a drop box and linked the file. used the same method described here and in XDA with the SDCard (which is what ive been doing) except he didn't extract the file..

      dropped in the MicroSD card and did the power off, than power on install method. It works. We kept extracting the files and moving them onto the MicroSD card afterwards and tried to install.

      Now it works, and it runs PERFECT. happy i returned that POS Xoom.

  • brad

    What if I want to revert back to the 3.0 ?

  • Tyler

    This is the official build.. why would you want to? This is a huge improvement and not some MOD.

    You can also get the 3.0 in XDA but the current one is 3.0.1 this one is 3.1

  • brad

    simple reason would be that if some of the additions that the OTA might have compared to the zip file that Im updating to .

  • brad

    And I updated. Wow
    Movie Studio, its there.
    The new live wallpaper.
    The new additions like Kindle, Zinio
    Resizeable widgets.
    The speed of the browser.
    No hiccups in Youtube or playing back HD files.

    Wow, damn good job. Im impressed.

  • Lou

    I've installed the update last night and been on it all day with no force closes, battery life is still great web browsing is fantastic! I did notice my quadrant score dropped from 1956 to 1586 on 3.1 but things are quick and smooth. Love this update, now I just need a case for my transformer and I'm set.

  • giank

    it all went fair.
    speed highly increased!
    hope soon there'll be a way to connect to ad-hoc wifi with some rooted mod.

  • brad.

    Ok, where is the movie apps that everyone is talking about on the OTA version of 3.1.
    I see movie studio for editing, but where is google movies. ?

    Am I missing something here.

  • Frass

    Please follow the steps in the SOP manual to update the firmware.


  • Jake Forsworth

    Is the download only for Asus transformer. Or can I put it on my phone?

  • Darryl

    I succesfully downloaded and installed 3.1 but have two observations to share inhopes it will help others.

    1. From the Rom boot i must have not hit the volume up key because like a previous user i wiped all the data off my tab.

    2. Since loading 3.1 my browser crashes frequently and the keyboard is slow. I have flasf 10.3 installed.

    Clarification or help on these issues is appreciated.
