  • (Necessary!!) Make sure that you have already installed custom recovery like Clockworkmod recovery or TWRP recovery on mobile. Without this recovery you cannot flash ROM on the mobile.
  • Here is the procedure to install TWRP recovery on HTC Explorer.

Procedure to flash Cyanogenmod 10.2 based on 4.3 Jelly Bean on HTC Explorer:

  • Download zip file of ROM from the source page. Also download kernel image from the same.
  • Since Google Apps are not pre-installed in the ROM, you have to separately download and flash them.
  1. Download Google Apps for CM 10.2
  • Connect your mobile to computer through USB cable. Ensure that you have enabled USB debugging on. Copy both files to the external memory. Don’t extract them.
  • Disconnect mobile from PC and Turn it off by long pressing power button.
  • Download the fastboot files which we will need to flash the kernel image.
  1. Fastboot Files
  • Extract above zip package of fastboot files. You will find four files inside your extracted folder.
  1. adb.exe
  2. AdbWinApi.dll
  3. AdbWinUsbApi.dll
  4. fastboot.exe

  • Open Kernel package which you’ve just downloaded in your computer. Search for boot.img inside it (which is kernel file). Extract that kernel file using WinRAR & copy the same in fastboot folder so that you should have total five files inside it by now.
  • On the phone (while switched off), enter into the fastboot mode. To do so,
  1. Press & hold Volume Down + Power Button together.
  2. Your device will be booted in bootloader mode. Now navigate Fastboot mode using volume up/down buttons & select it using power button.
  3. After entering into the Fastboot mode, Connect your phone to the PC.
  • Open the ‘Fastboot‘ folder in which you have extracted fastboot files.
  • Now Open command prompt & Point its directory to the fastboot folder (OR You can do the same as: open Fastboot folder, Press & hold shift key and then right click on the free space in the same folder.When right clicked (holding shift), you’ll see ‘Open Command window here‘ option. Click it & Command prompt will get opened pointing to the Fastboot directory).

  • Put this command in command prompt: fastboot devices (After entering this command, you’ll see the random numbers are appeared in the command prompt window.This is to ensure that your device is properly connected. If it doesn’t appear then you need to install HTC Sync software to install essential drivers for Explorer).
  • Type the following command in command prompt to flash the kernel file:

                           fastboot flash boot boot.img

  • Restart it in bootloader mode by typing “fastboot reboot bootloader” (without quotes) in command prompt. Once phone restarts then you can disconnect the phone from PC.


  • In bootloader mode, highlight recovery by using Volume Keys & Enter into the recovery by using Power Key. You’ll be landed into custom Recovery.
  • (Recommended!) Take a nandroid backup of current system. You might need it if something goes wrong. For that select backup & restore and then backup. This backup will be saved in external memory.
  • Now wipe data/factory reset and then wipe cache partition to wipe all the data and caches respectively from the phone.
  • Next step is flashing of ROM. To do so select install zip from sdcard and then choose zip from sdcard. Choose Cyanogenmod 10 file for installation.
  • This will take few minutes for installation.
  • Repeat the step of install zip from sdcard and choose zip from sdcard. But this time chose GApps Package.
  • After successful flashing of both the files, select +++++go back+++++ and then reboot system now. First start may take some more time than your usual restart.

Upgrading from Earlier version of Cyanogenmod:

  • Just copy ROM file and Gapps file to SD card and flash them through recovery. No need to do wipe data and wipe cache partitions.

Tip: If you don’t like this ROM or you are not comfortable with this ROM, you can easily return back to the previous ROM just by entering into the recovery mode. Then select backup & restore option followed by restore & chosoe your latest backup to restore.
