- Back up data and settings using a recommended custom recovery tool such as ClockworkMod (CWM) or TWRP, as data wiping process is mandatory in this tutorial.
- Download and install the correct USB drivers for Google Nexus 4 on computer.
- Ensure USB debugging mode is enabled on phone by navigating to Settings > Applications > Development or Settings > Developer Options.
- Double-check that the device has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing ROM.
- Make sure the device is unlocked (not locked to specific carrier) and rooted with ClockworkMod Recovery (CWM) installed.
- If device is stuck at booting or experiences boot loop issues, Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
- Allow newly installed ROM to stabilise for five minutes before using the device.
