[Supported Devices] borxnx:
Hi folks. I'll start off with some disclaimers.

I'm not part of the Jide team or in any way affiliated with RemixOS other than that I was given permission to post an "easy install" package here.

I cannot fix bugs. If you want to tell me about bugs you are welcome to, but there's nothing I can do about them. This thread *may* be monitored by Jide team members, but I cannot guarantee timeliness nor thoroughness.

I am only here to support this thread in regard to "How To Install It". That said, I will try to assist anyone with any issues that I can. I can't fix bugs, but I can answer question and may be able to resolve some issues.

This process WILL WIPE your device, so be sure to back up any important files beforehand.

Now that all that's out of the way, let's get to it.

If you haven't heard about RemixOS, here's a little intro: http://www.jide.com/remixos

Remix is a different kind of Android experience.

The only way to install RemixOS at this moment is through fastboot. I took their firmware files and simplified "flash-all" batch script and packaged it alongside ADB and fastboot. If you already have ADB and fastboot, you can download the firmware directly from Jide and install just like always: http://www.jide.com/remixos/devices/nexus9

If you don't have ADB or fastboot, or just want to speed up your install process, keep reading.

You will need an UNLOCKED BOOTLOADER to do this. Unlocking your bootloader will wipe your device, but so will installing this ROM normally, so again be sure to back up important files. Click the spoiler button in the instructions below to see the additional steps for unlocking your bootloader.

Pre-install: Enable "OEM Unlocking" in Developer Settings. To do this: go to "About Tablet" in Settings. Tap "Build Number" seven times. You'll see a notification that you are now a developer, and now you'll have a "Developer Options section in Settings. Go into Developer Options and enable "OEM Unlocking" by flipping the toggle.

1. DOWNLOAD EASY INSTALL PACKAGE:

2. Unzip the package. Just the .zip file you downloaded, no need to unzip anything within the original .zip file.

3. Boot your Nexus 9 into bootloader mode. (power off tablet, hold "Volume Down" and "Power" buttons simultaneously for 4-5 seconds. You'll see a white screen with multicolor text if successful)

4. Connect tablet to PC via microUSB cable.

To unlock bootloader, if necessary:

A. Hold Shift and right-click within the unzipped folder containing ADB and fastboot tools, then click "Open a command window here". A command prompt will pop up.

B. Type

fastboot oem unlock

C. This will wipe your device and takes a few minutes. If it reboots afterwards, get back into bootloader mode to continue.

5. Double-click "flash-all.bat", the batch file within the folder you unzipped from the package.

6. Wait for a while. It takes a few minutes. Do not unplug the tablet or turn off your computer during this process. It will reboot automatically when complete.

Congratulations, you are now running RemixOS 3.0!

A few notes for modders:

I was able to root using CF Auto Root.

TWRP works fine for flashing some .zips, but remember this is a heavily modified AOSP so not all mods will work.

I have not tested Xposed.

Layers do NOT work.

If you install a custom recovery or modify /system you will not be able to install OTA updates, you will have to flash the entire package manually.
