How to Install Custom ROM’s on Android devices (universal guide)
- First of all, on your computer you need to download the proper update file.
- Optional: download the Google apps package if it is not included on the firmware file.
- Save the files on desktop; don’t unzip them.
- Then, connect your handset with the computer.
- Establish the connecting by using the USB cord.
- Copy-paste or drag and drop the downloaded files from desktop to your phone’s (tablet’s) SD card.
- Disconnect the devices by unplugging the USB cable.
- Turn off your smartphone / tablet and wait a few seconds.
- Then reboot your gadget into recovery mode.
- Next, navigate through the recovery mode menu and select “wipe data factory reset”, “wipe cache partition” and “wipe dalvick cache”.
- The system will now be wiped out, so that’s why the backup has been recommended before.
- Up next, return to recovery main menu: select “+++go back+++”.
- And choose “install zip from SD card” and “choose zip from SD card”.
- Pick the update file and flash the same.
- Optional: repeat this operation for applying the Google Apps package.
- When the installation process ends, from recovery select “+++go back+++” and “reboot system now”.
- You are done.
In some cases after flashing the custom ROM, when rebooting the first time, your handset might get stuck in a boot loop (if the first boot takes longer than usual, don’t panic, there is nothing wrong with your device); if that happens, follow:
- Reboot in recovery once more.
- From there select “wipe data factory reset” and “wipe cache partition”.
- Return and reboot.
- Optional: if needed now you can restore the previous software (only if you had made a Nandroid backup as indicated). So, use the recovery menu and select “backup and restore”.
