HTC HD2 – Steps to Install Android 2.3 Gingerbread OS

HTC HD2 AndroidWhat if i say that you can install Android 2.3 Gingerbread on your HTC HD2 in simpler and in a shorter manner as many of us might agree with me that HTC HD2 has got a lame operating system that is Windows Mobile 6.0 version as the best part of this is due to the hardware of HTC HD2 you can install almost every android version ranging from Froyo to Gingerbread on your device. So, let’s proceed and check out how you can install the latest Gingerbread 2.3 version on HTC HD2. Thought the build is not a final one or 100% optimized one but is an AOSP build.

Procedure to install Gingerbread 2.3 on HTC HD2:

  • First of all you need to download the AOSP build file MDJ Android 2.3 Gingerbread AOSP Build for your HTC HD2 device and need to save the same on your desktop.
  • Now, you need to copy the Android folder into the root of your SD card. You need to copy the data.img file into the Android folder.
  • Now, you need to run the exe file with the name CLRXAD.exe on your HTC HD2 with the help of file explorer.
  • After running the exe file you will need to run the HARET.exe on your HTC HD2 device.

So within 10-15 minutes your HTC HD2 will boot up and there you go you can see that your device is now working on the Android’s Gingerbread operating system and not on lame Windows operating system 6.0. So, in just four simple steps to be precise you can easily install Gingerbread on your HTC HD2.

    I have followed the below steps

    – On computer, download and unzip indicated file – “MDJ Android 2.3 Gingerbread AOSP Build”
    – Connect Phone to Computer via USB, copy Android folder to root of SD-Card of Phone. I am not sure what does \root\ signify?
    – Copy one of data.img files (1024=T-Mobile_USA, 512=European) into phone’s Android folder. I copied 512 .img file as I have a phone I bought in India , unlocked
    – Detach USB connection (no longer needed) and when I see to run the files on my phone I don’t see ANDROID folder which I copied
    – I reconnect the phone to my PC and I see that the Android folder isn’t there.

    Please help me

    After spent lot of time looking for good advice how to install Android on my HTC HD2 Tmobile Usa, happily I found this excellent site. I read several times the instructions and the comments and experience from other users in order to avoid any problem and frustration in case of no success. I am extremelly satisfied now with Android. I was scared when a file .7z was copied but I found how to unzipped and finally …very important…Install the application to keep DUAL applications WP6.5 and Android, because after restarting the phone , it always got WP instead of Android. Now my phone have the two systems.
    Do not give up. Read this thread and learn from other’s experience. Thanks everybody !!!

Do i copy all 3 to the android folder then copy the android folder to the root on my hd2? Then run the two things inside the android folder from my cell? Also will this lock my phone if it is unlocked? I have never rooted before so please help!

    @Todd GenY DualBoot is another alternative you can use.

    • Tyson

      June 24, 2011 at 8:24 pm

      No offense meant; but I have the same issue of starting in windows. I went through the file explorer and ran the two exe’s in order to get back to android. But after reading these threads I may try dual boot setup. I went to the link above and the author is fairly clear right at the top about it not working on an htc hd2. Something about no snapdragon yet. This is just an FYI, not a flame. I’m a noob.

  90. Colin Garcia

    June 6, 2011 at 7:33 pm

    Can you put whatever apk files you want in the “AndroidApps” folder?

  91. Todd

    Here is a link to a simple program that will let you dual boot into either Windows or Android upon startup without having to go through file explorer.

        download dual boot from this link & follow following steps

        1. install android 2.3 on SD Card

        2. power off cell

        3. remove SD CArd and install JMZ dual boot

        4. power off cell

        5. insert SD card back in and turn on ur cell… should ask u for android or windows boot

    Dear Pradeep,

    Even after reading all the comments and replies, I’m still confused as to which img file need be copied and whereto?

    1. Copy all the folders (containing data.img) to Android folder?
    2. Copy all the folders (containing data.img to root?
    3. Copy selected file to root?
    4. Copy selected file to Android folder?

    If 3 or 4, which file? I bought the phone from India.

    Thanks in advance.

    battery will charge long time (3 hours)
    barrery backup is very low, when compared to 6.5
    internet data connection is turn off frequently because incoming call, incoming sms , outgoing cal
    internet data connection is donot turn on automatic
    camera photo is bad
    when andriod is running, at the same time card is removed, os is damaged
    when watching movie or torrent download, button lights turn on and turn off, it creat distrubance

      May 22, 2011 at 9:32 pm

      Dear Ashok V,

      u r clearly mis-informed, i run Ultimate Droid 3.3 (2.3.3) build off nand on my hd2…
      Video recording works (800×480)!!
      720P video playback!!
      GPS works !!
      Battery charges in less than 2 hrs and last for @least 30hrs (moderate usage)..
      Internet connection/ Suto sync connects & remains on regardless of calls, sms or mms…
      Camera (5MP) works!!
      Android is running off NAND and so i can unmount my sd card & re-mount whenever…

      Get ur facts straight before criticizing…Ignorance is no excuse.

      • Todd

        June 3, 2011 at 6:06 pm

        Well Voncrane, this comment thread isn’t about the Untimate Droid, it’s about this version of Gingerbread and everything he listed is valid. It doesn’t work. So unless you are running the ROM that this thread is about, then you shouldn’t call people ignorant. Sounds like you are the ignorant one who just came into a thread that you didn’t know about.

      • richard

  99. Yukeei

    May 4, 2011 at 11:49 pm

    All I get is the black screen — I’ve waited 20minutes, 40minutes and now, 45minutes before shutting off the phone (taking the battery out ’cause it won’t shut off normally), formatting the sd card, copying the files on it again and going through the steps one more time.

    Any idea why it’s not working? Should I let the phone try to boot up all by itself even if it means waiting a couple of hours?

      Hi Silvia,

      You should try to download the files again and unzip it. Please click the below link to download the files for Gingerbread 2.3 Android.

      If you still facing the same problem, then I think you dont have the unzip application in your system.

    If so, will my apps and contacts saved in the Android OS be delete?

    Thanks in advance

    • Neal Pradeep

      April 7, 2011 at 7:31 pm

      that depends on the coding actually, if it has that capability to use the apps simultaneously then it can be used but generally you cannot use.

    – Connect Phone to Computer via USB, copy Android folder to root of SD-Card of Phone
    – Copy one of data.img files (1024=T-Mobile_USA, 512=European) into phone’s Android folder
    – Detach USB connection (no longer needed)
    – On Phone, use File Explorer to go to Android folder, run (click) CLRXAD.exe
    – On Phone, same folder, run HARET.exe
    – Done. Watch Android Gingerbread boot up

    My phone now shows a black screen with a small amount of text in the top left corner informing me it is shutting down the hardware and jumping to Custom Kernel. Is this normal?

      Did you have the CLRXAD.exe or the CLRCAD.exe? With the CLRCAD.exe, it does not work and there is no CLRXAD.exe that is in the Android file. Please help, TIA1

    Installation procedure is not detailed enough. There is 3 data files, how we should handle them not mentioned.

    I will say, put the data file (for T-Mobile USA 1024, for European 512) into Android root directory.
