For the apps sync you need to go to play store and sync what you need from phone to watch ( play store from watch) it's new for android wear 2.0
[LG G Watch] darren1:
I was stuck on the same screen, I have just installed TWRP via fastboot and then reset and the port loaded in no time.
[LG G Watch] magicstick5:
Stuck on boot

Followed youtube vid steps, fastboot erase cache and userdata.

I then flashed both boot and system images.

Fastboot reboot and bootloop. Turned off using button and power on, no luck. Trying TWRP factory reset right now.

Anyone know a solution?

EDIT: Wiped userdata again, works.
[LG G Watch] darren1:
Animations can be turned off on Wear 2.0 via developer menu in settings. Hopefully this might help with any lag.

I cant get the ROM yo boot, im stuck on the 4 circles logo, someone who has the ROM booted can tell me how you did it?

Thanks
[LG G Watch] magicstick5:
This worked for me.

1. Follow steps that are given in the Youtube vid.

2. At the end, fastboot reboot

3. When you see the LG logo, swipe from top left to bottom right diagonally to enter bootloader.

4. Enter TWRP and factory reset.

5. Reboot system and wait. First boot WILL take a while.
[LG G Watch] fenix99355:

can someone make as script to do it. I have tried all methods and it just boot loops, trwp works fine
[LG G Watch] withoutname90:
Same problem here, no way to start, i get only bootloop with any boot.img (dory 2.0 official, 2 core mpdecision and 4 core mpdecision), with both TWRP or stock recovery and dory 2.0 system image.

TWRP 3 + squashfs is working fine but if i try to wipe system or data partition i get error on mounting.

i tried many time to reset back to stock with Rootjunky tool and i get bootloop also with this stable image.

in both cases twrp (both 2.8.5.0 or 3.0.0) or stock recovery are working fine, i get only an endless boot animation.

Please help, is there a way to wipe and reformat all the partition?

I used the following procedure and finally dory 2.0 booted up.

- fastboot oem unlock => already done

- fastboot format cache => NOT fastboot erase cache

- fastboot format userdata => NOT fastboot erase userdata

- fastboot format system => necessary for me but why?

- fastboot flash boot [boot.img] => dory 2.0 boot image

- fastboot flash system [system.img] => dory 2.0 system image

- fastboot reboot

Now is checking for update.

I got it on first day but somehow it settles later. Now I'm getting good battery just like Wear 1.5.

I'm not sure if it's because I played with it too often on first day.
[LG G Watch] FirefighterDown:
So I'm using dual boot img which is fast but Google Assistance response is slow. Any img which makes it faster?
[LG G Watch] bals:
Thanks for the upgrade to Wear 2 for LG G watch :svetius: . I am using Quad core boot image & quite satisfied with it. And I am able to run Net radio app (developed by me) directly similar to any music app in phone without any supporting app on phone.

But getting WiFi is a bit uncertain. I may have to reboot my phone & connect it to watch thro BT to get WiFi for using any net app like PlayStore or my music app. Any suggestion to improve wifi connectivity issues? Thanks.
[LG G Watch] reepje123:
The G Watch has no WiFi. Everything goes through BT.
[LG G Watch] bals:
Yes. I know that. But PlayStore & other apps in watch use phone's WiFi thro BT connection - facilitated by Android wear app. I think it is a sort of BT tethering provided by phone for G watch for which we do not have any control to enable/disable. That is what I meant. Android wear app shows "Connected" always but usage of PlayStore & other apps which need net connectivity is uncertain. If I reboot phone, it works most of the time. Are you able to download/update apps in watch from PlayStore always? Thanks.
[LG G Watch] reepje123:
My mistake, I misunderstood. There are multiple posts about connection problems with the Play Store in this thread so I guess we'll need to wait. Maybe it can be fixed in a future version.

I'm currently still on stock waiting for the next release.
[LG G Watch] motoralbi:
Quad core image should make it faster. On my side I see it takes some time only the first time you trigger the assistant, then the following times you say "OK google" the watch responds within 1 second, more or less.

[LG G Watch] Axel85:
Only to try and test, but you can try to download btauto tethering (the one with the green icon) from PlayStore. I use it to automatically share my phone connection to my car stereo through bluetooth when Bluetooth is connected . Even if I don't use it for my watch, because for me everything is working 100%, I can see the watch in the app menu to force sharing. Maybe it could help you to do some tries

Fastboot format doesn't work on macOS. Other commands like erase work fine though. Also, I dirty flashed MM over the 2.0 image without wiping, as well as erased system and flashed and it still bootloops, but now I can't use TWRP to wipe.
[LG G Watch] googleygoggles:
Well you're kinda stuck? The only way I found to fix it is to do the format command instead of erase. I feel like it's the erase command that borks things

I have a problem when i install boot.img, Minimal ADB say to me "image is not a boot image" ?? I'm confused and the result is that my watch is stuck on lg logo﻿. And the recovery mode dosen't work ( stuck on the android robot and no text appear )
[LG G Watch] Thisisabadname:
As soon as Android robot appears you have to do the swipe that you do to get into bootloader to get the options to show up

Might not be a swipe but I know you do something quickly after it shows up on the screen
[LG G Watch] motoralbi:
Nope.

Just do a swipe down from the upper border of the screen, so that the notification panel opens. There's the settings button there.

Edit: oh well just to tell you, yes you'll need to push the reset button in the tutorial, because notifications won't work until you finish it.

Hey guys finally G-Watch has Wear 2.0!! Followed the general thread for months, really glad to see finally the target is accomplished! Running it since Friday and all is working really nice!! Congrats to the developer.

Only one question, does anyone got telegram working? I can only see the blue loading ring rear welcome page.

Rest is all good.

Thanks in advance :)

Hey men! Thanks for your effort on bringing mpdecission to our SD400!! Did you manage to fix deep sleep?? Running dual core version but i cannot get more than five hours on it due this.

Thanks again and have a nice Monday!
[LG G Watch] thecreepy31:
But the menu doesn't appear when i'm doing the swipe when the android robot appear :(. Also, why when I install boot.img it fails ?

edit : nevermind, i just redownloaded boot.img and the cause is that i probably rename system.img by boot.img and redownload system. yep, a noob mistake ^^
[LG G Watch] googleygoggles:
Trying this ROM out again but this time with the quad core img. So far it's been working pretty predicatbly... I'll see how it'll hold up over the next couple of days. My question is why are all the watch faces round? Are they pulled from the G Watch R or something? Also, can we make the default faces square again? They look kinda weird on a square watch.
[LG G Watch] Thisisabadname:
Well I mean we did use the LG G Watch Urbane as a base for this rom

I just got watch faces off the play store (ones that I used on wear 1.6) and they remain square. A personal favorite of mine is Flash Clock.
[LG G Watch] spicyalan:
I took the risk of installing this.

It is now working fine, but I had some troubles installing. I did the "fastboot oem unlock" and installed TWRP3.0+squashfs recovery (from a post stating it to be compatible), then formatted and flashed as described in earlier posts. The watch always booted back into the recovery, no matter what I did. I just installed stock recovery again, and everything started working. Apparently, it does not really need the recovery as we are flashing through fastboot.

Everything works perfectly now. The keyboard is targetted to a round watch (but still, it works fine. Way better than no keyboard).

I'm using the 4-core kernel. It works way faster than 1-core, but maybe it might be interesting to see if it is possible to push one of the cores to a higher frequency than 787. This might improve app opening speeds further (unless the flash is being the bottleneck)

---------- Post added at 10:07 AM ---------- Previous post was at 09:24 AM ----------

I'm using the 4-core version and it seems that for most of the time the cores are in a "sleep" state (according to Aida64). Just scrolling fires up 1 core at 300-600mhz (up to 787Mhz), and sometimes fires up a second. Stock 1.5 always ran on one single 787Mhz.

It does seem to eat a lot of battery during installing applications (all cores firing). During sleep state (always on screen), my watch seems to use the same amount of energy as in 1.5.

Did you enable the setting to activate the watch by turning your wrist (I don't know the english translation)? Depending on the watchface, this might trigger a multi-core burst each time for a few seconds (this is a big drain if you rotate your arm a lot).

I don't know if mpdecision works in these boot images, but it does seem to behave nicely by putting cores to sleep (though this could also be handled by the governor). mpdecision might improve performance and battery by analyzing the workload better than a standard governor and fire up less cores. This might improve battery, especially during applications like heart-rate and sports stuff, which might trigger a performance profile while it is not needed.

How much it would improve is uncertain, unless tested. The SD400 has no big-little configuration, so a smart scheduler could also be enough.

Just to state: even LG (and/or Google) never got this part right, that's why these watches where just shipped with a 1-core configuration.
[LG G Watch] hardwareadictos:
I meant my G Watch doesn't enter in deep sleep state with dual core and quad core kernels :)
[LG G Watch] sun1000:
i have selected to do a factory reset in setting and now just boot loop to recovery....

[LG G Watch] bals:
Thanks for your feedback. Btauto tethering may be useful if a BT DUN client can be installed in the watch which will route net traffic to phone's WiFi through BT. Has anybody successfully used any BT DUN client which will automatically connect to phone's WiFi through BT ?

Are you able to use Play store always whenever you connect your watch to phone?
[LG G Watch] brostar2017:
Is there any benefit to me re flashing Android wear 2.0 again with the dual or 4 core boot image is there any advantage over it to the original boot IMG provided. It is a little laggy ATM but apart from that it's amazing, I can see why LG stopped there plans to do it. Also the instructions need to be updated, everyone that's having bootloop issues is because of trwp and wrong fastboot commands. Trwp is not needed, stock recovery is needed for it to work and fastboot format is needed not fastboot erase. Once I changed those two things no more bootloop and straight into wear 2.0

---------- Post added at 04:21 PM ---------- Previous post was at 04:20 PM ----------

The watch doesn't have WiFi itself, but it does already work with the phones wifi via the Android wear app.

---------- Post added at 04:23 PM ---------- Previous post was at 04:21 PM ----------

The issue seems to be trwp you will always bootloop if you use it. Only install with the stock recovery installed on the watch, also fastboot format cache, user data and system seems to help make it work.
[LG G Watch] sun1000:
yep seems that trwp cant clean recovery flag upon reboot
[LG G Watch] Novanic:
Hi,

I would like also to get Android Wear 2 on Samsung Gear Live. I'm an experienced software developer and have already flashed some custom rom, but I have no experiences in building custom roms, yet. How have you learned that? Is there a good tutorial / getting started or could you write the first steps you have done to get the initial version?

Thank you and best regards. :)
[LG G Watch] spicyalan:
Can you state your configuration settings (always on display, gesture setting, used watchface,...) and amount of screen usage (guessed) ?

Maybe a screenshot of battery usage might also be interesting.

Can you also check what it shows in AIDA64?

It seems that in my case (even with the 4-core kernel), battery usage is not that much different as in AW 1.5 except when it is needed.

- in sleep state with always on display, it uses a little more energy but I think this is more due to AW2 instead of the cpu. Generally, it is still handling +24hrs

- during training (heartrate monitor through Polar H7, watch displays heartrate continuously), battery usage is roughly the same. I had a 25% battery usage during a 2hr workout, which is on par with AW1.5

- When using programs like "play store" or installing applications, battery usage goes through the roof, because in this case it is revving up 3-4 cores (it seems art compilation only uses 2 threads, so 2 cores+the cores needed for the rest of the operations).
[LG G Watch] hardwareadictos:
Finally i fixed it factory resetting it! And yes, battery is almost the same as AW1.5 :)
[LG G Watch] spicyalan:
I noticed the cores scaling maximum speed is still 787Mhz (while the max speed of the cores is correctly 1200Mhz).

It would be interesting to try setting the scaling_max_frequency to 1190400 (maybe even only for core 0). This could help a few single threaded tasks, like starting programs. The governor seems to successfully scale down to lower speeds, so it might be that battery life is not impacted too much.
[LG G Watch] ab123321:
New update!

It is based on latest LG G Watch R image. Boot.img will be available soon, for now you can use one from previous build.

Note: now there is answer button during incoming calls!
[LG G Watch] Alexandgut:
Thank you very much for the update! I flashed the system and the quad boot image and everything seems to be working great.

Just a note to other users, It took thirteen minutes for everything to boot up, but I did not have to wipe anything and data was intact.
[LG G Watch] ericdabbs:
Im thinking about unlocking my LG G Watch bootloader and trying Android Wear 2.0. Any gotchas or things I have to be aware about when flashing this ROM?
[LG G Watch] Alexandgut:
I would just do it. I have not run into many of the problems others have run into. If you don't like the port, you can always return to stock. My only suggestion is to flash the 4 core boot image since it works best for me. As always though, YMMV.

I really enjoy Google assistant in my wrist for my smart home stuff. Battery life does take a slight hit. I lose about 15% more for my 14 hour day than I did before, but it makes it 14 hours!
[LG G Watch] bals:
Thanks for the update :good: . I updated only the new system image. It took about 10+ mins. It's working fine with Quad core image & gets connected to my phone without ant problem. But I am able to get WiFi connection only after rebooting my phone. That's the only problem. Great work.
[LG G Watch] Justatechie:
Thanks for the update.

Flashed it through fastboot without wipe or format and waited for 10 mins to see it boot up.

Now the watch is pretty much functional since we can answer to calls, but can also use developers options (just for me to prevent burn-in).

It's looking good and thank you again for all you are doing for the g watch.
[LG G Watch] Thisisabadname:
Guys the update fixes a big thing:
[LG G Watch] spicyalan:
All that was needed is a "fastboot flash system <system.img>" and a 10 minute reboot.

It feels more responsive in opening apps (though that might be a placebo effect)
[LG G Watch] kokesh:
Installing full FB lite is a better fix IMHO:)

---------- Post added at 09:22 AM ---------- Previous post was at 09:17 AM ----------

I didn't install anything and can use internet from installed apps (I have FB Lite apk and Messenger Lite installed in the watch and bot work 100%).
[LG G Watch] bals:
FB Lite & Messenger Lite apps installed in the watch uses FB & Messenger apps installed in the phone to communicate with the external world using phone's WiFi.

But I think apps like Play store uses Android Wear app to communicate with external world using Phone's WiFi. BT link from Watch to Phone is connected always but apps like Play store work some times. If phone is restarted then I am able to use Play store to install or update the software in the watch.

Are you able to use Play store always?
[LG G Watch] Thisisabadname:
I am. And pretty sure FB Lite and Messenger Lite don't use their full app counterparts for internet, considering it's mainly for phones and not meant to be put on a watch natively.
[LG G Watch] bals:
For your info, I installed only Messenger lite in the watch. But when I opened the app in the watch, an alert message " Install Messenger in the phone" showed up on the watch screen. This indicates that "Messenger Lite" app in the watch needs "Messenger" app to be installed in the phone to work properly. This is my viewpoint. Somebody may clarify this. Thanks.
[LG G Watch] MihaiSG:
You are right. Some apps needs also to be installed on the phone.
[LG G Watch] bals:
When I search for "Messenger Lite" in Play store through watch, it shows "Messenger" with version no 121.0..0.13.70. I installed this app in the watch which requires " Messenger" app in the phone to be opened for normal operation. But if I download "Messenger Lite" from Playstore & install it in watch from PC using ADB, this app works without any counterpart app on phone.
[LG G Watch] kokesh:
You are mixing two things: Messenger for wear (called just Messenger) and Messenger Lite - app made for countries like India, with data caps. It is full fledged phone app, only made to use less data. You can't install it from watch Play Store. You get the APK and install it via ADB. That thing doesn't have any idea that it runs on the watch.

Couple this with lowering the DPI on the watch and you get very nic, fully functional Messenger. Some dude even had Chrome running on the watch, but unsurprisingly it was very slow.
[LG G Watch] bals:
I am aware about this & fully agree with you. But I wanted to know if the apps like Play store works always in the watch. For me, it works sometimes & as I have mentioned in my previous posts, if the phone is rebooted & connected to watch through BT, I am able to update or download apps. I have seen many people raised this point. I think I am not the only person who face this problem.

I am sure this problem will get resolved soon. Thanks.
[LG G Watch] kokesh:
It takes a long time time before PlayStore loads/updates stuff sometimes. Hopefully it will get fixed. It is a bug in the ROM.
