There is no future for Nextbit Robin

Since Nextbit Systems was acquired by Razer, Robin's support was until February 2018.

If you update according to the message displayed on the notification of Robin terminal, the Android version will be as follows.

(As of 2017-05-26)

Android Version: 7.0
Android Security Patch Level: January 2017
Build number: Robin_Nougat_88

Our Robin has been updated to Android 7.0 and the following bug has surfaced.

It is played back intermittently as it gets caught during music playback
After inserting the earphone for a while, noise called buzz occurs

The above bug was unbearable, so I downgraded it to version 6.0.1, which was unavoidably stable.

Make a note of the steps I followed.

Factory Image

Nextbit Systems is tolerant of custom ROM introduction and routing, so even if custom rom is introduced to Robin, terminal security is effective.

In addition, we have published a factory image and a flash procedure so that you can return from the custom ROM to the factory settings.

You must unlock the boot loader to install Factory Image on Robin,

"YOU MUST HAVE YOUR BOOTLOADER UNLOCKED"

I just write, I do not teach me how to specifically release.

Subtlely unfriendly.

If you're stuck in a bootloop, or have your device by loading custom software on it, we've got you covered by offering our factory images. These images will help you get your Robin back to its original, out-of- What you will need to do is "flash" these images through your computer.

This link contains the files necessary to get your Robin back to the following:

Android Version: 7.0
