Warning: Although the tutorial shared below successfully flashes Custom ROMs onto your device, there are chances of you bricking your phone and making it useless. You need to have a rooted Android device to flash Custom ROMs. If you are a newbie and don’t know the abc of rooting, then I recommend you do not proceed. I or Dragon Blogger is no way responsible for any damages you do to your phone by following the tutorial below. Proceed at your own risk. You and only you are responsible…..
Lets proceed with the tutorial:
Step 1: Go to XDA Developers Forum and search for your device either by simply entering your device name in the search bar or by manufacturer in case your device doesn’t show in search results.
Step 2: Click on Android Development in the sub forum for your device.
Step 3: Check for Custom ROMs for your device. Download the ROM which has positive responses from all the previous users who flashed that particular ROM on their device.
Step 4: Copy the ROM into your Android’s SD card. You can also keep it in a folder.
Step 5: Boot into Clock Work Mod (CWM) recovery. Booting into CWM is different for different devices, so you can know the process by searching your device name in Google. You can navigate in CWM by using Volume rocker keys and select by using the center key.
Step 6: Once you are in CWM recovery, click on “Wipe data/reset”. Confirm your action in the next step.
Step 7: After wiping data, click on “Wipe Cache Partition”. Confirm your action in the next step.
Step 8: Go to Advanced > Wipe Dalvik Cache. Confirm your action in the next step. Then again go to advanced > Wipe Battery Stats.
Step 9: Navigate back to the main menu and click on “Install ZIP from SD card”.
Step 10: Select the Custom ROM and confirm your action in the next step.
Step 11: Your device may boot 1-2 times during the installation process. It is a normal process and nothing to be panicked.
Step 12: Once the installation process ends, click on “Reboot System Now”. First reboot might take 3-4 minutes.
Congrats, you have successfully flashed a Custom ROM.
