Google Nexus 4LG Press Kit

Last week, Google officially rolled out the new Android 7.0 Nougat to Nexus 6, Nexus 5X, Nexus 6P, Nexus 9, Nexus Player, Pixel C (laptop).

However, former flagship phone Nexus 4 is no longer eligible to receive firmware update, as the Google phone's software support warranty has expired. Users, who are still hanging to the 2012 device, you are in luck. XDA Developer Forum's recognised programmer, who goes by the moniker, Zaclimon, has come up with the Nougat-based AOSP (Android Open Source Project) ROM compatible with the Nexus 4.

It is 234MB in size and has no hint of bloat-wares. ASOP ROM brings all the goodies of Nougat including night mode, bundled notification, improved battery optimisation, multi-window options and numerous other value-added features to enhance users' experience.

Prerequisites (things to remember before installing Custom ROM):

  • This new Android Nougat AOSP  ROM has to be installed on the LG-Google Nexus 4 (aka Mako) only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
  • Make sure the device is rooted before going ahead with custom ROM installation
  • Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
  • Make sure you have installed USB drivers in the PC, or else your phone (Google Nexus 4) will not be recognised by the computer.
  • Make sure your device has more than 80 percent battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted mid-way.
  • Though installing custom ROM improve the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. IBTimes India cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked. Hence, users are advised to proceed with caution.]
