In late 2015, Google officially disbanded software update service to the Nexus 7 (2012) as the device was more than three years old and hence, it was not eligible to receive the Android Marshmallow.

That being said, people who are still hanging on to the Nexus 7 (2012) can experience the new OS by installing custom ROMs that are available in Internet. Among them, BeanStalk series firmware is one of the most popular out there.

Salient features of BeanStalk Android Marshmallow OS:

  • System UI tuner
  • original BeanStalk Wallpapers (developed by skyliner33v)
  • App circle bar
  • Built-in Task Manager switcher
  • Customisable navigation bar
  • Gesture anywhere feature
  • CyanogenMod based performance tweaks
  • Developer options and advanced reboot enabled by default
  • Toast animation feature
  • Do not disturb feature

Pre-requisites (things to remember before installing Custom ROM)

  • Though installing custom ROM improves 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].
  • Make sure the device is rooted before going forward for custom ROM installation.
  • This new BeanStalk Android 6.0 Marshmallow custom ROM series has to be installed on Google Nexus 7 (2012) model only; if tried on other devices, it might bricked them [To check your device model: Go to Settings >> About phone >> model number]
  • Installation of custom ROM requires clearing of memory in the tablet, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
  • Make sure USB driver is installed in the PC, or else your device (Google Nexus 7) will not be recognised by the computer.
  • Make sure your device has more than 80 percent battery, or else there is chance of tablet getting temporarily bricked if the installation process is interrupted mid-way.

[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.]
