Android 2.2 build for Evo leaked, rooted -- and released

Android hackers strike again, this time with the upcoming Android 2.2 release for the Evo 4G -- it's already been found, rooted and made available for your flashing pleasure.  Avalaunchmods has beat everyone to the punch and cranked out the first Evo 2.2 ROM with Sense, and everything working.  Enough of my talking, I have a ROM to flash -- and some of you do too.  Hit the source link for download instructions and links [xda-developers] Thanks for the tip and the ROM Avalaunchmods!

Update: HTC's pulled its link and gone on Twitter with the following: "Please be aware any floating around for EVO are not final and may cause problems. Official updates are coming OTA next week!" You've been warned!

  • WOW
  • kick ass work Gary. <3
  • I love root I can switch between cyanogen 6 and this htc sense 2.2 root!
    Right now I'm digging the cyanogen 6 but I removed adw and added launcher 2-1(stock android)!
  • I don't get it.. if it's the official rom, how come it needs to be rooted to be put on an evo?
  • This. I just downloaded it directly from HTCs site, and loaded it as a recovery. No rooting, no adding Sense needed. Sounds like someone is taking credit for doing pretty much nothing.
  • or someone got the update early, figured out how to root it so people using custom recovery and are already rooted can use it too, and posted it up. This is a major deal, especially since he beat HTC to the punch.
  • sweet im so happy thank you
  • Doesn't have to be but now we don't have to wait for a rooted version. This is a good thing!
  • Sorry meant to reply to slayersp
  • Apparently here: and here: ...are downloads for the STOCK ROM. According to the sites both of them will break root. I'm reluctant to do it, being that the last update bricked my phone, but I want Froyo so bad... Post here if anyone uses these downloads to get the STOCK ROM and if it's a successful download and flashing.
  • Okay I am so confused. If I get this on my phone will I have full root with nand unlock or just kinda sorta root? Sorry for the stupid question.
  • Neither, get the 1.32 ruu run that, find on xda noob root guide for evo, the flash this, you have to be rooted allready
  • I don't understand either how is this the official version of 2.2 I thought it was gonna b easy download
  • Okay, I'm bone stock.. how the heck to I install this?
  • You dont you need root! F u c k I n g learn something
  • Newb question, doing it this way, does it save all your contacts or does it just wipe everything out?
  • Download the Android 2.2 firmware for the EVO –
    Rename the file and copy it to your microSD card via USB. [Note: make sure the file is named and not]
    Power down your EVO
    Hold down the “Volume Down” button as you power the phone back on.
    A screen should appear showing your phone’s system searching for various files. Scroll down to “recovery” and press the “Power” button.
    When you see the triangle with an exclamation point symbol, press the “Power” and “Volume Up” buttons at the same time.
    From the menu that appears, select “Apply”
    When the screen displays “Install from sdcard complete” select “reboot system now” and wait for the phone to power back up.
  • where was this post when i was struggling trying to figure out what to do. it took a long time before that light lit in my head telling me to rename the file. lol
  • Where do I get the file from and u mean download it to my computer
  • i downloaded the source file from
  • Thanks for the detailed instructions! I was a bit stuck on how to apply this.
  • Sorry, I'm a little confused, so I'm going to sacrifice my dignity for the sake of those that follow. Am I correct that this ROM is different from the official stock 2.2 update from HTC in that this one is pre-rooted? If so, was this one based on the official ROM?
  • If you head over to xda thread, lots of issues with this. Not to denigrate the good work over there, but man it is like the wild west. Some guys just got to shout "First!" and the barflies will ignore some major inconveniences just to jump in. Wade in with extreme caution. I await a fully function rooted EVO froyo.
  • Your wait is over, this is fully funcktional
  • mine is stuck at the "Loading, this may take several minutes" for a good 45min
  • Worked for me, Froyo working fine. Android-wifi-tether not working, but it does say that it is for 2.1 only.
  • You all missed the point here. i can see its a bunch of newbies to rooting and everything. Avalaunch had got the update before HTC had a chance to release it. He rooted it FOR THOSE THAT HAVE ROOT so we can update with out losing our root. BUT YET AGAIN! there's also a leaked HTC version out in the blue that is NOT ROOTED. and thats for normal phones.. If you don't want to lose your data then just wait to Aug 3rd or load the HTC source that is out in the blue. . If you have root then use avalaunchmods to keep your root! Correct me if im wrong. even tho i stand strongly correct here
  • I installed this and everything works except wifi tether I cannot get to work, but it does have root.
  • WIfi it in green wifi symbol
  • wiped and installed the ava 2.2, wifi tether working fine here.
  • Think i'll wait until it's downloadable in ROM Manager...
  • does anybody can tell me how to aply this i download renamed and cant be out on the phone it telles me does not find it any ideas. thank you
  • I'm guessing you have the Android 2.1.1 update, and never rooted your evo before. I think this froyo root can only be used if your phone is already rooted, just to keep root, but update to froyo.
