Hello, my phone s7 edge doesn't sync with my watch gear s2 with android wear. I need help!!!!

Which instructions & packages did you use? Trying to get a 'new to me' Gear 2 working.

I didn't use more instructions than showed in this thread. Only I can't pair wacht and phone so searching videos I found a user with the same problem and I tried out to install the version 1.5 of wear app. After two devices will be paired and you'll be able update to the latest version of wear app. I hope you'll have luck!!!

I got the watch setup too, and now I'm also having problems getting the watch & phone paired. When I installed version 1.5 of the Google Wear app, it immediately insists on auto-updating to the latest version, and I never get a chance to try pairing. How did you avoid this?

Go to the play store swipe from the left side to open the menu>settings>auto update apps change the setting to do not auto update apps, after you've paired your watch you're free to turn auto updates back on if you wish :)

Muchas gracias!!!!

Hello friends, I recently bought a Gear 2 and I could not connect it in any way to my xiaomi MI A1 until I found this great firmware. Now I can use it every day, I receive messages from WhatsApp y much more. Muchas gracias! Ojalá el creador de este firmware lo actualice pronto.

    Hello everyone!
    Android Wear for Gear 2 / Gear 2 Neo

    This thread is about development of Android Wear for Gear 2 & Gear 2 Neo
    IF YOU HAVE A QUESTION, ASK IT HERE: http://forum.xda-developers.com/gear-2/help/qa-porting-android-to-gear-2-t3018159

    attachment.php.jpg bootlogo.jpg wearboot.php.jpginstallgplay.jpgscreenshot.jpgIMG_20150514_204055.jpgIMG_20150514_100754.jpg

    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.

    • 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
    Not working:
    • 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"

    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

    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

    @alvaromartinezb Walkthrough video on audio: https://www.youtube.com/watch?v=klYqseFd90g
    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 (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.

    *. Walkthrough video by @alvaromartinezb : https://www.youtube.com/watch?v=LhzIqFopQNY&feature=youtu.be
    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
    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:

    *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:

    And then follow these steps:
    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
    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

    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
    Moving on

    So, I'm sorry to tell you this, guys, but the day has finally come.

    Some months ago, I started having some issues with my Gear Neo. I would flash anything, and the watch would stop flashing midway dropping a "failed" message on Odin, or wouldn't boot after flashing. After a lot of trying, I finally was able to bring it back to life, but sometimes, the watch would still randomly reboot, show random force closes, and sudden battery drains. The reason for this is that the flash chip in my watch was slowly dying and corrupting the data inside. Those problems have only gone worse, to the point where it can't stay running for more than a minute without dying. I've been testing it over and over again and the result is always the same: I can zero out an entire partition, and read it back and see that some parts get zeroed, and some others read 4, 6, or random characters. That and the kernel dropping I/O errors all the time in dmesg show what that means: after more than a thousand kernels and systems flashed, the flash chip finally gave up.

    I've thought of getting another one to replace it, but my life has changed dramatically and I don't have much time to work on anything lately, and if I were to buy another watch, I think money would be better spent in something newer after all.

    I started this project 20 months ago, with no idea on how to make Android run, a very limited set of skills, and without knowing if I'd ever get anything running in the watch. Finally we ended up with a mostly complete Android Wear experience, iterating through 3 major Wear versions on a watch which was never designed to run it, and with an amazing community helping each other with all issues that have arised through time.

    It's been really fun working on this, and I'm really, deeply thankful for each and every person in this forum which has participated in any way with this project, either making videos, reporting issues or just helping others.

    So, to everyone, since I can't mention the more than 500 persons I was mentioning in this post, THANK YOU, I really hope we'll meet again in another project!
    I'll be in the Gear S forum trying to make this damned, horribly programmed, and full of issues watch behave :)
    Welcome home

    Welcome home, Android
    I've spent four months searching for you :)

    We still have a lot of work, but it's nice to see you finally showing up!

    Edit: Logcat here -> http://pastebin.com/rSPLTCrX

    *flies away to repair all the crashing stuff*
    Already got the update file thanks to @tritus! Took a quick look, version is a little up (MEC23L) but not as up as emulator (MU) and does have Google TTS services. I pushed it into my watch and it fails almost every time I try to start it. In fact, it behaves exactly as the emulator APK. Renders ambient mode half dead and walking like a zombie in the background eating my battery..

    Update is a mix of binary patches/new files, so it'll take me a little while to make a master system image and patch all my stuff into it. We'll see how it works when the framework version is up!

    Will keep you guys posted!
