Over a period of this article we will be checking out on what are the list of pre requisites you need to follow and then we will check out a detailed tutorial in the next page.

Essential pre Requisites:

  • All the data present in your phone should be backed up as in the process of applying this update, the data might get either lost or corrupted. With the help of below mentioned steps you can easily backup the same. After updating with this release, the HTC Sync won’t recognize the device as it’s a custom ROM firmware.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Call Log – Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • Disable all the antivirus suites in your computer and uninstall the same in your device as these tools generally tend to interrupt the process of firmware update.
  • Minimum charge left in the device should be at least 60% so as to ensure that device doesn’t get turned Off in the middle of firmware update.
  • Enable the USB Debugging in your Galaxy Advance from the path “Settings > Applications > Development > USB debugging”. The USB Debugging option should be ticked as shown in the below screen capture.

So assuming that you have followed all the above mentioned steps, you now need to proceed to next page where we have mentioned a detailed tutorial on how to install the custom ROM firmware in HTC Desire.

Procedure to update Mild Wild 3.9 Custom ROM Firmware:

  • Download the Mild Wild Custom ROM Firmware package from here to your computer and once you do this, you need to connect the computer and copy this zip file in the device. Ensure that you are not placing the file deep into the sub folders.
  • Disconnect the phone from computer and turn Off the phone so that it can be then entered in the recovery mode. The recovery mode in htc Desire can be entered by pressing the Volume Down button + Power Button till you see the recovery mode screen on your phone.

Recovery Mode Procedure

  • Once the recovery mode is entered, you need to select “install zip from sd card” > “choose zip from sd card” and then choose the Mild Wild 3.9 Custom ROM Firmware Package. As soon as you select the file, it will take up to 5 minutes to update the same in your device.

HTC Desire Recovery Mode

  • Once the firmware is updated successfully, the device will land up in the recovery mode screen where you need to select Wipe data/factory reset and also you need to select Wipe Cache partition and then reboot your device by selecting reboot system now with the help of Volume rocker keys. Once it’s done, you then will have to select the option of “reboot system now” for restarting the device.
  • Once you see the home screen, disconnect the phone from the computer and there you go, you are ready to play with your phone.

Note: At any point of time just in case if the process of firmware update gets stopped due to any reason, all you need to do is restart the process from the start by re inserting the battery.
