How to enter flash mode

If your Gear 2 is not linked to a Samsung phone, you have to bypass the first screen. Click around 20 times on the watch symbol until the Bluetooth message pops up, then wait until it disappears and then long press the watch symbol once. See this video.

Long press Power to force a reboot (the regular software restart button does not work for accessing the menu), then press Power quickly multiple times to go into the boot menu. You can navigate to downloading mode by pressing Power and then waiting a few seconds.

Mainline

The device has mainline support, added by Samsung. See here

Needs this patch to get the kernel to load on a retail unit.

Mainline does not currently boot very far, seems to be stuck on Exynos DRM.

GUI
