thanks for this. I'm a noob at messing with the watch. I thought I'd never root it or unlock in any way but google forced me to it.

They decided that 1 core at 700mhz is enough? they're probably trying to force the watch users to accept that the watch is old and they need a new one. I'm glad I found this thread and flashed the dual core option. The watch is super responsive now. I was very scared when flashing the boot.img since my watch doesnt sit stable in the dock and it keeps disconnecting. I managed to get it to "sit" for like 3 mins and flashed it.
[LG G Watch R] N3CR0M4NC3R:
Not having any luck here, got as far as unlocking the bootloader and it is correctly showing in fastboot as lockstate unlocked but i cannot seem to flash ANY of the img files, using the command fastboot flash boot 4-boot.img just throws me a no such file or directory in cmd, the img file is in the root directory along with all the platform tools, what exactly am i doing wrong here?
[LG G Watch R] AndiTails:
You need the command prompt to be in that folder too.

It's easier to type everything up to the filename, hit space, then use the mouse to drag the file into the CMD window. It'll type in the full location and name for you. Then hit return.
[LG G Watch R] N3CR0M4NC3R:
And that did the job, cheers for that!

Pretty simple thing to miss but it has been quite some years since i was last actively flashing bootloaders and firmwares :P

I'm interested in root too, have you found a way to root stock aw2? [MENTION=622139]stevep113[/MENTION]

I flashed latest supersu in twrp but got no good results :(

Try skins ROM the boot IMG will root on reboot

Watch shutdown with new kernel : Cause is kernel, not battery.

Hello everybody,

I've juste bougth an good old W110 (LG G Watch R...) yesterday. I've tested it all the afternoon. Good battery life, good perfs.

It was on AW 1.5.

After charging, I upgraded it to AW2.0. All the application and watch faces were keeped. Still working.

Performances were still correct, but when I tried some advanced wear 2 functions (playstore, etc.) It slowed down... OK.

So, this morning I've upgraded the kernel for the "2-boot.img" one.

First, OEM unlock. OK.

Then simple boot (fastboot boot 2-boot.img)... bootloop... (Or boot too long for me :) ).

So i've flashed the kernel. OK, it booted (on the craddle). I started to resync the watch with my nexus phone. So I take the watch out off the craddle an started the process....

And the watch shuted down !

I boot it again, immediate shutdown...

1st conclusion :

The battery is GOOD. It have been tested and It worked fine.

So the modified kernel killed the watch !!

Conclusion : For some watchs don't use it !!!

OK. So why ? It is strange... But... I have a backup of the AW 2.0 original kernel :) !

So I flashed it back...

And the watch ressurected !:)

So 1st conclusion is confirmed : The cause is in the kernel !

OK... so why it failed ? Battery ? I don't think so.

As failure arrives when we take the watch out of the craddle, taking logcat may be difficulte...

Correction can be taken is some direction : Thermal shutown ? Is the watch not getting too hot ? And when in the craddle the security disabled ,or the temp when the shutdown occure not the same ?

Is there any "watchdog" configured in the kernel that must be disabled ?

For people wanting to "revive" theire watch here is a link to the original working kernel :

Look for NXG47C boot image.
[LG G Watch R] ianrobbie:
Just wanted to jump in and say "thanks!".

I installed the 4 core kernel (my watch is recharged every night anyway so no battery concerns) and the difference it has made is nothing short of remarkable.

No more two/three second waits for menus to open or gestures to register and everything is nice and snappy again.

Thanks very much!
[LG G Watch R] Pawelss:
hi,

I'd eliminate thermal issues, I've been using the dual-core kernel for a while now (since the day I replied for the first time in this thread) and I can confirm that the watch does NOT get warm during any type of use. The battery life has been slightly improved in my case, the watch lasts exactly 48 hours of normal use (its 2 years old). Perhaps there is more than 1 hardware version or something? maybe a different battery manufacturer and that could cause the shutdown? I'm no expert but I think we should be able to see it in fastboot?

here's a picture of my devices fastoot menu:

[IMG="gwr fastboot"]https://i.imgur.com/BpWrho2.jpg[/IMG]

it says rev_10

I assume thats version 1.0 so go ahead and confirm that yours match too.

edit:

as for your 2-core bootloop, I gotta say that it took like 10 - 15 minutes to boot.
[LG G Watch R] nicogri:
This mod changed my watch (not my life ^^)

It was slow and barelly dead with AW2 and now it is as snappy as my Huawei Watch !!!

I don't understand why LG is not putting this simple modification in all the watches ?

Question is : should I flash original boot image to perform OTA update or can I go for it right away ?

---------- Post added at 19:27 ---------- Previous post was at 18:40 ----------

OK so auto reply to myself ^^

Flashed original boot just to be sure and then OTA which took arround 15 minutes (check reboot flash reboot)

Now watch looks snappy and working fast.

How to check if LG didn't finally change governor or cores numbers ?

I will wait to know what settings are in the new image (if new) berfore reflashing 2 cores version

By the way here its new build number

Edit :

Going back to 2 cores version

Edit 2 : OK seems like going back to 2 cores was not a good idea at all...

Now I am bootlooping so maybe boot image was tied up to the update more than I think.

Now I think I need to wait with my watch sutdown until new files are released for new OTA.

Or flash back complete previous firmware through ADB and wait

Edit3 : I think that [MENTION=3557264]boorce.com[/MENTION] had the same issue (3 posts ago)

Maybe his watch updated directly to latest AW2 and he faces incompatibility...

As I don't know how much time I need to wait for OP (or some other guy) to got the update and then dump boot.img and then patch it or so I am gonna try to flash back previous AW2

That is what appens when you flash and flash and flash and never make backups ;)
[LG G Watch R] apexhugger:
I have been using both the 2 core and 4 core versions and it's great. It has made my watch usable again. AW 2.0 ground my GWR to a halt, google assistant took a long time to load, incoming phone calls would just display a blank screen so I couldn't tell who was calling. Now these functions happen almost instantly.

Not all that much difference for me between 2 and 4 cores in terms of battery life. But the 4 cores is a little faster.

Can someone tell me how to backup the stock kernel or can upload the stock kernel for me to download. Right now I have to upload the modified kernel everytime I reboot the GWR.

Thanks!
[LG G Watch R] nicogri:
Maybe you only use the fastboot boot command instead of fastboot flash command...

I will try to modify new boot image as many people is requesting so, but I still haven't received my OTA and I will need a link to the zip file in order to get it to my computer, will try once I get it
[LG G Watch R] nicogri:
Thanks pablotiss.

I am checking here and on reddit for the first person to give the OTA link.

This way I can extract boot image too

Anyway thanks for your work for community

PS : You should add a big red line on top of your original post telling people not to use your boot image if they receive the update ;)

[LG G Watch R] Aerandir14:
I flashed this kernel around 2 weeks ago and this morning I got the OTA notification on my watch. Tried to install, it rebooted but it seems like it didn't do the update (I'm still on March security patch).

I flash the original boot.img around 8h ago, did a factory reset, re-locked the bootloader but still no update notification...

Is there a reason for this?

EDIT: I flashed the stock boot.img, recovery.img and system.img via fastboot and I got the OTA straight!

[LG G Watch R] nicogri:
Thanks man that's the stuff ;)

I flashed it on recovery... got a xfer 1.16x message on adb but I saw boot.img patched just before.

Watch booted good so I am up to date and on 1 core.

[MENTION=1917650]tampitzel[/MENTION] you can use this file to get your watch up and running !
[LG G Watch R] pablotiss:
I'm currently facing a problem with OTA zip, the new zip is an incremental update, what means it only has part of the boot image (the changed ones), thus I cannot use it to directly flash to a device. I also have the previous boot.img, applying the patch to the new image should give the new one, while I don't know how can I apply it to a file, I have tried using the command that android recovery uses to flash it through the Android shell, but it only works for partitions, not files.

Any ideas will be welcome
[LG G Watch R] nicogri:
I think easiest way is to dump a full updated boot.img after the update using adb.

But need to be root to do so
[LG G Watch R] ianrobbie:
Hi all. Just a quick question. I recently reset my watch and now, after setting it all up again, it's prompting that an OTA update is available?

I have the 4 core kernel flashed and was wondering if I update will I need to re flash?
[LG G Watch R] Discotetak:
Before I flashed the custom recovery and rooted the watch, I was able to flash the different versions of this kernel using the Windroid Toolkit v3.1 - I tried the 1 and 2 core versions and settled on 1 core. Now, after I flashed the TWRP recovery and rooted it, I'm no longer able to flash the 2 core kernel - I don't get an error, but when I check the number of active cores in AIDA64, only the 1st one is active. What I am doing wrong?

Thank you!

Actually, nevermind - I managed to flash it from the TWRP recovery
[LG G Watch R] N3CR0M4NC3R:
Got the notification here of the update here on my watch too,

just seems like a security hotfix with a few optimisations for single core usage..

im still on the 4 core kernel and won't be updating until it works with the newer update, thanks for all your ongoing work!
[LG G Watch R] apexhugger:
My watch updated to 7.1.1 (AW 2.0.0.156099718), Bootloader LENOKZ22B, Build ID NXH19X, Incremental 4010769, Kernel Version 3.10.40-g17dadfc and the modified kernel is no longer booting. Just gets stuck in a boot loop with the watch getting very hot. Looking forward to a new modified kernel as the GWR is still slow. :)
[LG G Watch R] mieszk3:
After restoring an original boot image and update to the newest firmware version (NXH19X) I can tell that there is a difference in watch's work. Now it works a lot better then the first AW2.0 version.
[LG G Watch R] Pawelss:
does it work better or as good as the dual/quad core kernels? I remember that the original AW2.0 slowed down after a few hours of regular usage.

if it's still not as good then I'm not gonna bother with LGs updates and just sit on the modified kernel.
[LG G Watch R] mieszk3:
Works better, almost like 2 cores kernel.

Ok thanks. I've just received this watch used but in good shape and I must say AW is really sluggish compared to AW 1.5 in my original squared g watch. The watch is really beautiful, specially compared to the squared one

[LG G Watch R] scotta316:
I really have to disagree. I've been using the update for about a week, and my GWR is just as slow as ever. Maybe you're using a simpler watchface now than you were then, as I've found that makes a difference. I still find the watch barely usable, and I can't wait for these kernels to be updated to work with the update
[LG G Watch R] Aerandir14:
Did you do a factory reset after installing the update? I'm using a watchface with 3 complications and it's pretty usable.

Envoyé de mon XT1635-02 en utilisant Tapatalk
[LG G Watch R] Ambious:
I too found that watchfaces have a huge effect on the performance.

I used to use an animated watchface which would basically cause the watch to grind to a halt every so often.

Now I use a really simple one and it's noticeably faster - I'd dare say several times faster.
[LG G Watch R] Pawelss:
it's a downgrade if I have to use a simple watchface. I've been using the Neo watchface on AW1.5 and it's been great. now on AW2.0 (without the dual-core kernel) it works like trash. If they force us to use simplier watchfaces then it's definitely step in the wrong direction.

as a sidenote, any of you use facebook? if so, did you notice how tideous it is to answer with voice reply? it's literally easier to pull the phone from your pocket and do it there.. you gotta enter the notification, pull up the 'answer' sheet, then go to 'voice call' and finally choose the microphone icon..... waay to many actions need to be taken in order to reply to a message. I really liked it in AW1.5.
[LG G Watch R] kitchenfork:
I installed Skin1980's ROM and kernel and I can't believe the difference compared to stock, even with animated watch faces. Stock AW 2.0 in my opinion is barely useable. Looking forward to the May update.
[LG G Watch R] pablotiss:
Updated version is already available on main post
[LG G Watch R] KromerX:
Thanks a lot!

Is that possible to get full 4 cores version not only at boot?

I have used previous kernel version from you with 4 cores support and I'm super happy with it. Love that performance!
[LG G Watch R] damefrikis:
Thanks a lot. Yesterday I just downgraded to 1.5 in order to compare performance and battery life with my original g watch.

Is AW 2 working as smooth as 1.5 with this kernel mod? If that, I'll take the plunge and reflash the last version again

Thanks for your work!

Also happy to see you consider that,

I use the 4 core kernel on a daily basis and have enjoyed its smoothness :D
[LG G Watch R] mieszk3:
After flashing new kernel, my watch shows battery level at 50%. Even during charging level stays on 50%.

Ok, never mind - it was a watch issue, not a kernel. Putting it on the charger when turned off fixed the problem.
[LG G Watch R] drewcu:
Appreciate your work on the new kernel [MENTION=7409002]pablotiss[/MENTION] and would greatly appreciate another unlocked 1-core version as well.

Thanks!
[LG G Watch R] SeTM:
Please remove 4 core mod on boot. The watches turns off if it's not charging. After switching on 2 cores, after loading, everything works fine.
[LG G Watch R] adal86:
the problem is not the watch booting up with 4 cores, but your old battery that cant supply the required energy to do so...

I had issues with my watch being unable to boot off the cradle until I replaced my watch's battery...
[LG G Watch R] SeTM:
I agree with you, but with 2 cores (and stock) there is no such problem. I agree to wait a little more for the boot, but without the charger.
[LG G Watch R] apexhugger:
Fantastic work as usual! My GWR is working very nicely now with your modified dual core kernel and the latest AW update. Thanks! And thanks for also uploading the original NXH19X kernel for rollback :)
[LG G Watch R] scotta316:
Thank you so much for this! While I was waiting for this, I bought a Samsung Gear S3 on Ebay. (I got the Classic since I already have a sport style smart watch.) It's a very nice watch, but I was already missing some of the things I depended on with Android Wear. Now my GWR is like a new watch too. Thank you again.

Just curious, is there a way to verify that my watch is using 2 cores? I'm pretty new at adb and fastboot, and I'd just like to know I did it right
[LG G Watch R] raptoro07:
Somewhere there is a kernel auditor specifically for our watch. You can side load that. However, I can tell by how quickly the settings menu pops up when I press the button. There is a lot of lag if you are stock.
[LG G Watch R] GFX:
My preferred method is to check on AIDA64, you can download it from the watch play store and it will tell you everything about your device, including CPU frequencies per core and governor.
[LG G Watch R] scotta316:
Thanks. I was just about to edit my post and mention that I found AIDA64, which confirmed I was using 2 cores.

My batttery life is a little shorter with this kernel. I use Sleep as Android to monitor sleep, and it didn't quite make it through the 5:25 sleep I had today. (Not a complaint, just an observation)
[LG G Watch R] maartenw8:
Am I the only one who is experiencing extremely slow download speeds in the play store? I haven't had a successful download yet because of the speed..
[LG G Watch R] N3CR0M4NC3R:
No issues here on my watch, atleast not at home anyway..

Generally after a complete factory reset when re-downloading and re-syncing apps from my phone to the watch it's done in a matter of seconds

Only thing i am missing here is a complete quad core kernel,

I might be one of the few who actually used it on a daily basis and didnt see that much drain compared to the modified dual core kernel
[LG G Watch R] maartenw8:
Lucky you! Do you download over WiFi or Bluetooth? My play store really is unusable..

---------- Post added at 08:52 PM ---------- Previous post was at 08:49 PM ----------

Downloading over WiFi works for me.
[LG G Watch R] N3CR0M4NC3R:
At home i download over wifi , i have a 300mbps line with virgin media so bandwidth isnt a problem even though i know the watch isnt using all of it

In regards to using standard LTE on my S7 edge and bluetooth it does take a little longer but nothing too extreme, i'd say its still within reason even for larger applications
[LG G Watch R] yanniclord:
Hmm, i am already running the latest version (NXH19X), but i get a bootloop. The "original kernel" in the top of the topic, do i need to flash that with the NXH19X version BEFORE i flash the modified kernel?

EDIT: After i flashed a fresh new NXH19X system, and then flashed the "original kernel" to prevent a bootloop, ye, guess what happened: The Watch doesn't boot, just fantastic. So i now have to again flash the stock system just so that i can wait 15 minutes for my Watch to start up again. Can anybody explain me on how to flash this kernel on NXH19X directly without any issues? I tried through TWRP and through bootloader, all it does is either give me a bootloop or not boot at all, only the stock system works.

---------- Post added at 09:54 AM ---------- Previous post was at 09:05 AM ----------

Alright, so after i finished the Watch Setup, i tried flashing the KERNEL in the bootloader, it DID work, however, now i am facing the problem of the clock shutting the second i take it off the charging pad. Not just that, but it even turns off multiple times during boot, or cannot be booted at all without being on the chargepad.

Oh ye, battery is at 75%. Not just that, but the watch shuts down after like being for 1 minute turned on and staying on the charging pad. What now?

Sorry for the wall of text, i fixed it by letting the clock stay turned off for 5-10 minutes and let it cool down. Then i rebooted it multiple times until it stayed on :)
[LG G Watch R] Na!th:
Nice to hear. I never had the problem with the shutdowns.

This mod actually works much smoother then the one from skin1980. I guess its because there is no hotplug and always 4 cores active (worse for the battery then!).
[LG G Watch R] andrep182:
Hi, I'm trying to understand a bit more about this kernel. In this thread, people were mentioning how some are using 2 cores and others are using 4 cores kernel. However, in the main post, there is only one version of boot image in the link for "Latest modified kernel for NXH19X" (I'm assuming this is the one I should use for AW 2.0 May security). Is that conversation old now? is there only 1 unified image available now, with 2 cores running during normal operations and 4 cores during boot up, as explained in the main post?
[LG G Watch R] AndiTails:
Yes, exactly that.

Originally, there were 2 versions. But it's now been unified.

There wasn't much difference between 2-core and 4-core when actually using the watch, but the 4-core had a bit more battery drain, so this unified version makes perfect sense ('cos bootup can be a little slow!).
[LG G Watch R] andrep182:
Thanks for the confirmation man. I successfully loaded up the kernel last night. So far it feels more responsive, but at the same time, the watch was also wiped out clean. I'll keep playing around with it and see =)
[LG G Watch R] pablotiss:
New kernel available with boot fixes and new versions :)
[LG G Watch R] andrep182:
Hey man, what's your battery usage for sleep tracking with 2 cores now? Mine drains about 50% , I just wanna see if you get about the same. Are you using "sleep as android"?
[LG G Watch R] maartenw8:
Hey!

Currently I'm not using the kernel anymore. I flashed ext4all (ROM) and now the watch is very stable and fast with a great battery life!

However, my sleep as Android battery drain was still almost a full battrry per night..
[LG G Watch R] andrep182:
Holy crap, almost full huh? Do you sleep 12 hours a day!?! ;) . I guess I have to accept the fact that it drains 50% for me. I think it's worth it considering how much snappier my watch gets now
[LG G Watch R] maartenw8:
Yes indeed.. Or try the ROM! It's a great battery life and very stable watch!!

I wouldn't. This kernel was for the may patch. My watch rebooted to install but couldn't with custom kernel. I'd wait till a new kernel is released.
