Current development stage
Kernel:: Still work in progress. Most functions are working correctly. Expect some bugs.
GITHUB REPO: Github Android B2 Repository
Recovery:: Minimal image. Not actively worked on, but enough to wipe and access ADB: MediaFire
Android: Most of it is working, and for me at least, IS usable. Some things are still missing and will need to be worked out though.
Working:
Android Wear 6
Remember: These are BETA, things may or may not work. No support, no nothing, just sharing them with you so you can play with them. I already know what works and what doesn't, and I'm trying to fix everything

Installing

User @alvaromartinezb has made a really good video explaining what you have to do, check it out! https://www.youtube.com/watch?v=bBqg72z8LOk&feature=youtu.be

KNOWN ISSUES
USB doesn't work! --> Check if you're running latest build, check your drivers. Windows 7 may have some issues with MTP
ADB doesn't work! --> You might need to manually install the driver on the device manager in Windows (you can use Google SDK's bundled driver)
Battery doesn't last! --> Be careful with battery hog watchfaces, some will prevent the watch from entering suspend, or keep the heart rate sensor active at all times.
I can't play music from the watch to the speaker --> I haven't found an app that works. We're the only people with a speaker on an Android Wear device, and there aren't many 3rd party apps for that. Driver level is OK
I can't take photos! --> Work in progress, everything takes time, and my watch doesn't even have a camera!
Calls don't get routed through the watch and without it I will die! --> Then go back to Tizen. That functionality doesn't exist in Android Wear, and hundreds of hours of work for a function that probably wouldn't end up working anyway. And I hated it when I had it on Tizen, it only gave my phone issues when connecting to my car's bluetooth handsfree, and forcing me to choose back my phone on each and every call. I'm not developing that. If you want to try to code it yourself and you succeed, I can link to your work if you want, but I'm not wasting my time on that.
Going back to Tizen
BE ADVISED: GOING BACK TO TIZEN MIGHT PROVE DIFFICULT TO ANYBODY WITHOUT KNOWLEDGE OF THE WATCH, SDB, ADB, AND ANYONE WHO DOESN'T USE ODIN. DON'T PM ME FOR IT. IT'S WRITTEN BELOW. ASK IN THE Q&A SECTION PLEASE. THIS IS A DEVELOPMENT THREAD, AND THESE IMAGES ARE FOR DEVELOPMENT ONLY.
BE ADVISED (again): There's no PIT file for this watch. If your favourite flashing app for samsung phones requests one, use Odin. I know, I don't like it either. But we live in a world full of virtual machines with the ability to share USB ports. Now it's your chance to use them if you don't feel like installing Windows in your machine.

1. Flash this file: http://www.mediafire.com/download/3cg2eazoouur0bs/Tizenmod-Full-Restore.tar
2. When it fails to boot and the screen goes blank, reboot to the bootloader menu and select recovery.
Extreme Recovery mode - Only use if above method doesn't work
YOU NEED TO KNOW HOW TO USE ADB/SDB FOR THIS.
It may happen that you try to recover your watch but for whatever reason it still enters a bootloop when attempting to boot Tizen. This might happen if you played with partitions, if some permissions were set where they shouldn't be, etc. If you enter recovery mode in Tizen and you don't see a confirmation that the watch is being restored to default, you can try this:
First of all download everything from this folder:
https://www.mediafire.com/folder/a1tcatuw1a8t3/Full_Restore
And then follow these steps:
Some info about the device
Gear 2 specifications
Samsung Exynos 3250, dual core up to 1GHz
512 Mb of RAM
4 Gb of flash, divided in 15 partitions (see below)
Mali 400 GPU, using Exynos DRM driver
YMU381 audio, supported by ALSA
BCM4334W Bluetooth/WLAN controller, already supported by Android in a bunch of phones
Samsung SensorHub (STM32) controlling Gyro/accelerometer and HRM. Supported in the kernel and seen in Android HAL.
Partition layout
bota0 -> ../../mmcblk0p1
bota1 -> ../../mmcblk0p2
csa -> ../../mmcblk0p3 --> ext4 -> /csa
boot -> ../../mmcblk0p5 --> Main Kernel
csc -> ../../mmcblk0p12 --> ext4 -> /system/csc
fota -> ../../mmcblk0p10 --> seems empty
ramdisk-recovery -> mmcblk0p8 -> ext4 -> Unused in tizen --> USED AS BOOT PARTITION IN ANDROID
module -> ../../mmcblk0p9 --> ext4 -> /lib/modules --> USED FOR TWRP IN ANDROID
rootfs -> ../../mmcblk0p15 ext4 "/" --> Root file system, recovery works from here too. If you break it it will only boot to download mode. --> USED AS SYSTEM PARTITION IN ANDROID
system -> ../../mmcblk0p11 EMPTY --> Did samsung start with Android on this thing then changed their minds?
system-data -> ../../mmcblk0p13 --> ext4, /opt --> If you erase this partition, your watch won't boot back into Tizen. Do not touch it unless you have a backup and know your way into restoring it.
user -> ../../mmcblk0p14 EXT4, /opt/usr --> all user data, including the MTP available part (/opt/usr/media) --> USED AS DATA & SDCARD IN ANDROID

DISCLAIMER
Code:
Your warranty is now void. Not only void,
it's not comming back. The moment you
flash anything on this thread you can say
goodbye to it. I almost hard bricked my
watch once. It can happen to you too.
I do my best to post things that aren't
dangerous for the device, but anything
as simple as a 9 instead of a 4 in the GPU
driver might make it overheat and kill it.
Everything here is at your own risk.
You have been warned.
Current development stage
Kernel:: Still work in progress. Most functions are working correctly. Expect some bugs.
GITHUB REPO: Github Android B2 Repository
Recovery:: Minimal image. Not actively worked on, but enough to wipe and access ADB: MediaFire
Android: Most of it is working, and for me at least, IS usable. Some things are still missing and will need to be worked out though.
Working:
- Boot
- USB: ADB, MTP [july 19th]
- Display: Software rendering, OpenGL and mixed compositions
- Screen dimming
- Screen always on
- Battery reporting and charging
- Oportunistic Sleep (kernel)
- Bluetooth: basic functionality (working for notifications, music control etc), Tethered internet access (still some bugs to work out though)
- Vibration
- Heart Rate Monitor
- Accelerometer sensor
- Step counter
- Gyroscope (this includes tilt to wake)
- Power management: CPU Hotplugging, frequency scaling, Amoled LPM, runtime suspend and opportunistic sleep.
Depending on use, can give from 12 to 48 hours of battery life. Normal use gives me about 18-20 hours with screen always on - Audio: Input and Output
- Infrared
- Basic TWRP recovery functions
- Camera
- There's no way of playing music to the speaker directly from the watch
- There's no gallery app
- Palm-on-screen to suspend
- Anything that's not specifically put as "working"

*NOTE* This is highly destructive. You do this wrong, your watch might not boot again. I'm not responsible for whatever damage you do to your watch.
First of all download everything from this folder:
https://www.mediafire.com/folder/a1tcatuw1a8t3/Full_Restore
And then follow these steps:
Code:
1. Flash TizenModFull
It will start rebooting itself
2. Flash recovery_fota_cache
3. Enter recovery, and run the following commands through ADB:
adb shell ->
umount /data
mount /dev/block/mmcblk0p15 /system
mount /dev/block/mmcblk0p13 /system/opt
mount /dev/block/mmcblk0p14 /system/opt/usr
rm -rf /system/opt
cp /system/usr/system/RestoreDir/opt.zip /system
cd /system
unzip opt.zip
sync
cd /
umount /system/opt/usr
umount /system/opt
umount /system
Exit the shell and select "Reboot -> PowerOff" from TWRP
4. Now press and hold the power button until "Rebooting..." appears, then enter Download mode
5. Flash kernel_tizen.tar
6. Reboot again to download mode
7. Flash tizenmod2.tar
