Battery	Battery life seems to be bad on Treble, compared being on the stock firmware. Low battery power mode will somewhat help with this.

Basic Flashing Guide

This is assuming your device is brand-new, with a locked bootloader. You should also have adb installed on your computer with the appropriate drivers. Make sure your device has a good charge before continuing.

Pre-Flash

1. Boot your device and skip through the setup procedure. A Wi-Fi connection is not required for this process.
2. Open the Setting menu, go to System, About tablet, and enable developer mode by tapping the Build number field several times. Hint: watch for the popup at the bottom of the screen to tell you how many times you need to tap the Build number.
3. Go back to the System menu, and open the new Developer options menu.
4. Toggle OEM unlocking to unlock your bootloader.
5. Toggle USB debugging, and accept the popup.
6. Connect your tablet with a USB cable. You should see a popup asking if you want to allow USB debugging. Check the Always allow box, and tap OK.

Ready to flash

1. Open a terminal on your computer, and type adb devices to verify that your tablet is available and ready to accept commands. You should see a response similar to this:

List of devices attached

[your device's serial number here] device

If you see an error message, double-check that your tablet has been authorized with your computer. You may need to disconnect/reconnect it, or restart the adb server (adb kill-server).

2. Now that adb is ready, reboot into the bootloader with adb reboot bootloader. The screen will go blank, and in a few moments you should see => FASTBOOT mode... at the bottom of your screen.
3. Enter fastboot flashing unlock. You will see a warning appear on the tablet. Press the Volume Up button on your tablet to accept. Your bootloader is now completely unlocked, and all user data has been erased.
4. Wipe the System partition by entering fastboot erase system. You will see output confirming this action.
5. Enter fastboot -u flash system name_of_system.img, where system name_of_system.img is the name of the ROM image you'd like to flash. You should see some output as the image is written to memory. This may take several minutes. Interrupting this process may require that you have to restart the flash process.
6. Finally, enter fastboot reboot. Your device will reboot several times, at one point showing an erasing screen. Allow the device to continue and it will eventually boot into your new system.
