Cyanogenmod on Desire HD

September 26, 2011 6 comments

Its been almost 10 months since I got my hands on HTC Desire HD phone and had got a decent update to 2.3 from HTC site. But the only issue was the battery hogging HTC Sense and apps like stocks, weather eating my battery and 3G data. Who cares about the weather in bangalore? Just go out and enjoy the sun / rains..

Ok coming back to rooting the phone..  It just took me few google searches to decide the best custom rom in android market was cyanogenmod. For more info of custom roms visit –  To install the custom rom’s you need root access to your phone. HTC provides boot loader for certain phones ( but I was not going to wait for them to release for my desire HD. So decided to take a risk, void my warranty and go ahead with unlocking the phone.

Warning: Please note you are doing this at your own risk! There is a high chance that this might damage your device, or make it inoperable.


What you need :

Firstly is to create a GoldCard SD card. By doing so you wont be getting the “CID Incorrect” error message while unlocking in the next step.


  1. Go to android market and search for GoldCard Helper and install it on your phone.
  2. Run the app and note down Card:mmc2, Reverse CID’ value, making sure to use mmc2 and not mmc1.
  3. Go to site and paste your reverse CID number along with your personal mail address.
  4. Check you mailbox and download the goldcard image to your computer.
  5. Launch HxD hex editor on your computer by right-clicking it and clicking ‘Run as Administrator’.
  6. Mount your SD card to your computer, using your phone.
  7. Go to ‘Extra’ menu > ‘Open Disk’.
  8. Select Removable Disk (which should be your SD card) under Physical Disk (and NOT logical disk), uncheck ‘Open as Readonly’ and click OK.
  9. Go to the ‘Extra’ > ‘Open Disk Image’ and open the goldcard image downloaded in Step 5.
  10. Select ’512 (Hard disks/Floppy disks)’ as the sector size when prompted and click ‘OK’.
  11. In the goldcard image tab, go to ‘Edit’ > ‘Select All’ and then ‘Edit’ >’Copy’.
  12. In the ‘Removable Disk’ tab, highlight offset (line) 00000000 to offset (line) 00000170 including the 00000170 line and go to  ’Edit’ menu > ‘Paste Write’.
  13. Click ‘File’ > ‘Save’ and accept any warning that you get.

Now that your SD card is ready for downgrading. Follow the procedure to downgrade to 1.32

  • Download the attached file from here (right click to save file as) <Downgrade folder>
  • Extract the file to reveal a downgrade folder and copy it onto your C drive
  • Download this file stock 1.32
  • Connect Desire HD to a computer. Charge only, USB Debugging enabled!
  • Open Command prompt and navigate to the downgrade folder
  • If you placed the downgrade folder in your c: drive type in cd/Downgrade
  • It should show C:\Downgrade>
  • Carefully type in the following commands one by one

adb push psneuter /data/local/tmp

adb push misc_version /data/local/tmp

adb shell chmod 777 /data/local/tmp/psneuter

adb shell chmod 777 /data/local/tmp/misc_version

adb shell /data/local/tmp/psneuter

adb shell

NOTE: You should have the “#” sign instead of the “$”. If you do, you have temporary root, and can continue on.

/data/local/tmp/misc_version -s 1.31.405.3

If you did not get root access then follow these commands :

adb push misc_version /data/local/tmp

adb push fre3vo /data/local/tmp

adb shell chmod 777 /data/local/tmp/fre3vo

adb shell chmod 777 /data/local/tmp/misc_version

adb shell

./data/local/tmp/fre3vo -debug -start FBB00000 -end FFFFFFFF

cd /data/local/tmp

./misc_version -s 1.31.405.6

  • Copy to your SD card.  Don’t extract it and don’t rename the ZIP file.
  • On the computer, open terminal and run the following command:.

adb reboot bootloader

  • Use Volume up/down keys on the HTC Desire HD for navigation and Power key for confirmation. Select Fastboot to flash the 1.32.405.6 firmware.

Wait now till the downgrade is complete. Next step is to unlock the phone and gain root access. To root the phone we need visionary software and it is placed in the downgrade folder. File : com.modaco.visionaryplus.r14.apk. Copy this file onto your phone and run this apk file using File Manager or any software of your choice which can run apk files. Once the visionary is running follow these steps :

  • Check “Set system r/w after root”
  • click Temproot now wait patiently till it finishes.
  • once you have successfully Temprooted
  • Click PermRoot the device and wait for it to restart the Device.

Once you are done you have root access to your phone. The next step is to S-off the device.

  • Open the the Desire hd radio tool.
  • Select Radio S-Off and run it!!

Now you have an android 2.2 build 2.32 phone with root access which is ready for installation of custom roms 🙂

Installing CyanogenMod (copied from cyanogens mode site)

  •  Download the latest version of CyanogenMod.
  •  Optional: Download the Google Apps for the device.
  •  Place the CyanogenMod file on the root of the SD card.
  •  Optional: Place the Google Apps .zip on the root of the SD card also.
  •  Boot into the ClockworkMod Recovery using visionary tool.
  • Once the device boots into the ClockworkMod Recovery, use the side volume buttons to move around.
  • Optional: Select backup and restore to create a backup of current installation

Android on VM.

March 9, 2011 Leave a comment

The only thing which was missing in my gadget collection was an android phone. I wanted to explore the features of android OS before buying a phone. After Googling for 10 minutes, I landed on android-x86. Downloaded the 2.2 generic version of the iso file and installed it on VMware Workstation. Got the android home screen in 5 minutes. Connected my laptop to wifi setting and started to use all the features. After playing with it for few minutes i was pretty much impressed with android. Here are some of the screen shot i captured while i was working on android-x86.

If anyone is interested on trying this, let me know. Ill upload the vmx file onto some shared folder so you can also try it out.

Iphone to W595

February 22, 2010 2 comments

After a year of using Iphone i was literally fed up with the phone. You need to be too careful with the phone like a costly glass vase in your hand.. Its just not for me.. The touch goes for a toss if you get it in touch with water(got drenched in rain), the battery is so horrible, huge in size and syncing with itunes – you need to be crazy to keep the same set of data in different machines before you sync. Are you CRAZY!!

Its got its own advantages but for me not worth the trouble. So i decided to get rid of the weed and got a very nice deal. Maybe Bangalore guys are still excited with the phone.

I have got back to my sony walkman series and its a nice small phone. Hope its not so delicate as iphone.. Reviews after a week of usage.. 🙂

BYE iphone.. May your chip rest in peace or irritate the new owner.. 🙂

Digital Camera Modes

January 7, 2010 Leave a comment

I have been clicking from past year and half in my canon s5is and i think i am improving as the time has moved on. Well till now its been more of trial and error. I had no interest to read the manuals or any big posts to understand what the camera is doing. Basically till now 80% of my shots were taken in auto mode and i did not understand what the camera had selected to get a nice shot.

Well now its time for a change and after going thru Digital Camera Modes article in i have realized its not just an auto mode to clique. Its a start for starters like me to know more.

I have started to try out other modes and play around. When will you start??
