[ROM - DEV] WearOS 2 for Gear S3

[lavasbey]

Approximately how long does the battery last with wear os installed?

Battery drains very quickly by the screen. If you keep the screen on, it'll last one hour tops. But if you close the always on and keep the screen closed when you don't use it, it has a pretty solid usage time. Approximately a day and a half in my case.

Thanks for make this. Hope you can find a way to install wearos on Amazfit Verge. Maybe it's little easier because old Amazfit Watch use Android on their watch but it's not wearos.

Never had an experience with Amazfit Verge. No CPU info, it has 512MB ram which is not enough for running WearOS smoothly. Sorry.

hey seniors sorry to say but i forget to turn off my reactivation lock sadly my watch stuck saying custom binary blocked by reactivation lock.. i can't go into wireless mode please can you solve my problem how to fix this ?

The only way is soldering USB cable and flashing Tizen firmware with Odin.

Never mind, I just realized it could be only not showing the ap Mode text because the weird green text, I was right, double click in power button and I found the wireless network in my laptop.

Hi, I am glad you made it. It is also a known bug

Same green text on Wireless Download Mode. It prevents debug messages (Switching to AP mode etc) but functionality is not effected.

My watch is still connected to usb. So I can not say anything about battery life. I have still things to do for power management and kernel improvements. Also it depends on your battery's health. With disabled wifi (auto to completely off), always on screen, gps from settings, it can save your day.

I've been noticing that recharging is quite slow. Not sure how or what, but it's been 12 hours and I have to reboot it a couple of times to get more charge. 12:01 PM started charging -> 22:07 PM and it's only 83%.

P.S. I'm not sure if I could extract some logs wirelessly from my watch. If so, I'd love to share them if that would be more helpful.

Yeah that was an issue on my case too. Not that slow tho. Maybe try turning of the screen, if you didn't already, will solve a bit of your problem.

Watch automatically boots when chager is connected, but booting eats too much battery. When my charger and my watch heats up, it's like impossible to charge it. It is just looping.

Sooo, maybe adding an on off switch on auto boot solves the problem for a while?

Hey, yeah, my screen is turned off. I just notice that there is a couple of percentage charging. But then gets stuck on a certain percentage, rebooting seems to fix it for a couple more percentage. And for heat, it's been quite the same temperature as usual from my perspective.

What do you mean with the automatic boot? I've noticed my watch been crashing sometimes (not sure how or what, just out of nowhere with no repeatable process to simulate it) and it just restarts itself. Is that what you mean?

I've been keeping track of the battery life combined with my settings, maybe it'll be handy in the future to keep track of it.

No, I meant the booting after you connect your charger. Wheter you close the watch by shutting down or drain the battery to 0 percent, it stills boots when you connect to the charger. Maybe power off'd charging would be more usable.

And also, yeah. You have a different problem there. I don't know what to say to you. It looks like a background app has an issue. Maybe your watchface is the problem? I don't know.

Wow that's way to quick to make it worth it. Will there be a way to make it better in the future?

I can't find software with version r760XXU2FUD1. can i flash any other version if yes then please recommend me senior. can i flash software that you had given in MEGA cloud ?

 

[Reimagine]

I know youve probably heard this a lot but youve trully done what no one else could. I am glad youre getting some media coverage on this.

If you could have battery stability and NFC working for google pay, I dont see why this wouldnt be the main OS for all of the gear s3's in use out there (mine included).

I wish you the best <3

 

[catamai98]

I installed it, a few bugs here and there, but incredibly smooth. Very good work, I need just google pay and I will never need anything from a watch

 

[Umbardacil]

Yeah

NFC is all what we are waiting for

Imagine my disappointment when i spent 500€ back in the days for a high tech watch, and i couldn't pay with it although it was hardware ready (my county - Poland ) doesn't support Samsung Pay.

So i wish OP good luck and i keep my fingers crossed. If your project becomes daily driver with Google payment method i will find a way to donate you

I feel you, Romania here, same situation.

Coming back to the charging issue. I've placed my 0% battery on the charger today, and it went from 10:00 0% to 12:20 100%. I changed the watch face, but also disabled wifi and location. I also cleaned my charger a bit. Not sure what caused it, but it works fine.

 

[catamai98]

Only annoying problem that I have is with the vibration, is not working always and when is working it is very weak

I don't think i have felt it vibrate once but everytime i check it i have notifications

 

[Solidsnake892022]

Wow grande!
Ci sarà anche un port per Galaxy Watch?

DOWNLOAD WearOS 2 (Based on latest H MR2)
DOWNLOAD WearOS 2 (ALTERNATIVE)

GEAR S3 ONLY!! Installed and tested on a few SM-R760 Frontier and get succeed. In theory SM-R770 Classic will work too. They use same kernel and hardware.

BUT Korean and LTE versions are NOT TESTED. THEY USE DIFFERENT KERNEL CONFIGURATION. IT WILL PROBABLY CAUSE HARD BRICK!! USE YOUR OWN RISK!

BEFORE INSTALLATION

• DISABLE REACTIVATION LOCK
• Charge your watch to 100%
• Keep your device charging while installing firmware
• Have a stable computer with Wifi
• Take note your current Tizen firmware version for going back to Tizen
• Backup all your data
• Keep your watch close to your wireless adapter

INSTALLATION (View Detailed Document Here)

• Flashing process is the same as flashing combination or Tizen firmware
• Wireless flashing takes 15~45 minutes.

1. Extract downloaded zip file to get tar file
2. Enter wireless download mode
3. Switch to AP mode
4. Connect to watch from your wireless adapter
5. Select tar file for AP section
6. Flash

DO NOT interrupt flashing process!
DO NOT shutdown your computer or allow your computer to sleep!
DO NOT enter recovery before WearOS boots completely!

KNOWN BUGS

• Poor Battery Life compared to Tizen (Old device, new operation system)
• Audio (Low sound level, bad quality)
• HFP calls on watch (Bad noises, distorted sound)
• If you remove your watch from charger, WearOS charging indicator keeps showing until reboot. Prevents battery saving mode. Disables vibration for notifications.
• Some menus on Settings belongs to Ticwatch (just ignore them)
• Offline charging boots device

• Selinux is in Permissive mode
• ADB Root is active
• KNOX will be tripped!!

RESETTING WATCH OR CONNECTING NEW DEVICE
NEVER use WearOS settings menu to reset watch!!! It is not tested and may be brick your device.

Option 1: Flash WearOS again
Option 2: Boot to TWRP and Wipe Data (IMPORTANT! Be sure “Use rm -rf instead of formatting” is selected on TWRP settings. (TWRP Settings -> General Settings)

GOING BACK TO TIZEN

1. Find and download your Tizen firmware from internet. (Remember, you took note your firmware version before installation)
2. If you can not find your firmware you can try THIS TIZEN FIRMWARE. (It may has different CSC. Be careful!)
3. Flash

can you port also to galaxy watch3?

 

[tsp12 haha]

I know it's getting tiring how a lot of people say they created an account just for this. I just wanted to say that it worked perfectly! Yes, although it still thinks it's charging after taking it off the wireless charging thing, it still works completely fine! I downloaded it through the Wireless Download menu, as definitely a non expert in these type of things, it was quite easy to install! Thank you for basically bringing back life to this old watch.

 

[catamai98]

Now I have one day of use, and is working great, only the problem with vibration and google pay. Battery seems pretty normal to me, maybe a little bit worse but not a big difference. Awesome work

 

[Amperro.]

Cant wait to get NFC working. Keep up good work kind man!!
