Sorted it... Deleted drivers and then reinstalled.... Now to flash this kernel..... Then to twrp(which on is best?)

---------- Post added at 03:04 PM ---------- Previous post was at 02:07 PM ----------

Think its flashed but not sure... is there away to check?

---------- Post added at 03:30 PM ---------- Previous post was at 03:04 PM ----------

Based on the assumption it has actually flashed... I have noticed a bug.... Am getting RANDOM vibrates... some are a long single and some are a short double vibrate... and no there are no messages nore are there anyother notifications either on my phone!!! didn't happen on stock kernel.... SO can only assume its custom kernel!
[Sony Smartwatch 3] alex6600:
OP updated with version 3.1.

Try do reduce ZRAM SWAP size to 64 MB.

And few patches from 2.x version.
[Sony Smartwatch 3] alex6600:
Try to use stock kernel little more. Will see not only this issue.

Random vibrates can call one of the application. It is not necessary that this is the kernel issue.

From tomorrow I use my kernel, and not observed something like this.
[Sony Smartwatch 3] lohtse:
Had used the Stock kernel since yesterday and no such issue.... also noticed that apps are bing closed... Eg wear media is constntly being shut down when transferring songs.... again this was not the case with stock.!
[Sony Smartwatch 3] alex6600:
This 6 release issue, I think.

As can I see- memory leak in Android 6 is much more then in 5.
[Sony Smartwatch 3] lohtse:
Have been using this version (3.12.6) for over 24hours and had NO random reboots. Very stable with NO laggs and though on my watch it is a little battery hungry it has perfomed VERY well so far...

Dev has been fantastic with this and cannot say thank you enough for there hard work..

I certainly recommend this kernel.
[Sony Smartwatch 3] mickael91210:
Thanks, I will wait for full Rom so....

I can try to underclock with kernel adiutor : http://xdaforums.com/smartwatch-3/development/mec24h-twrp-root-busybox-kernel-adiutor-t3365990

I may improve your battery
[Sony Smartwatch 3] 13ONK:
So I've had a few reboots during the day after flashing 3.12.6. Version 3.10 seemed to work best for me but I'd still get reboots every now and then. Going to try stock for a bit and see if it still does it. It's always when I expand a card, usually email notifications. I've pulled a bug report right after my last reboot on 3.12.6. It's to big to upload here (5mb) but I can email it to you if you think it'll help. Just pm me where and I'll send it over.
[Sony Smartwatch 3] Momogs:
Been using 3.12.6 for close to 24 hours. Had one random reboot but otherwise battery life is good considering that I use Sleep as Android which is a known battery drainer--I'm at 40% now and it would be more if I didn't use that app. Keep up the great work!
[Sony Smartwatch 3] alex6600:
Any of configuration, kernel, build.prop tuning causes random reboots for me. Most of cases- when receive many notifications, or "heavy" watch usage.

For now- I not have any idea how to fix this.

Today I try to build full stock kernel with only increased swap. Other things left as in stock (2 active cores, many unnecessary modules, etc). And make tests...

PS. Anyone have experience with stock kernel, and intensive watch usage?
[Sony Smartwatch 3] lohtse:
One of the things that I KNOW was causing some of my random reboots was the WATCHMAKER APP... Soon as I stopped using it for watchfaces on my SW3 my random reboots went to around ONE a day MAX... And recently I have had NO random reboots...

I would suggest that it is NOT always the watch/kernel thats at fault but some of the apps that may be in use on our devices that actually cause the reboots...
[Sony Smartwatch 3] alex6600:
Random reboots should be 0 at all. Like in lollipop...
[Sony Smartwatch 3] lohtse:
Agreed... but I did have reboots on LP so am wondering if my issues had always been APP related?
[Sony Smartwatch 3] alex6600:
Stock kernel also causes random reboots?
[Sony Smartwatch 3] 13ONK:
I haven't had any reboots since flashing the 4 core unlocked stock build. It's been roughly a day, so to early to call it flawless but it seems more stable.
[Sony Smartwatch 3] Tikerz:
I'm using your 4 core stock kernel and have not had any random reboots.
[Sony Smartwatch 3] kam33mitch:
I've been using the two core stock kernel for two days with no reboots. the 3.12 had re-booted twice on me and the battery drain was higher than the stock kernel. Strange but that is what I've seen so far.
[Sony Smartwatch 3] snake218:
Been using latest version, still getting reboots :(
[Sony Smartwatch 3] lohtse:
check you apps.... I found that watchmaker caused my reboots...
[Sony Smartwatch 3] Simba83:
Since I stopped using mini Launcher things have been better.
[Sony Smartwatch 3] snake218:
I think wear messages may be the cause, but all was fine on LL. I think it's not the kernel fault , maybe this MM version sucks :)
[Sony Smartwatch 3] alex6600:
I'm going to build full stock kernel with 4 core from sources.
[Sony Smartwatch 3] alex6600:
Ok guys.

This is FULL STOCK build from FULL STOCK sources, with unlocked 4 cores, and FIOPS scheduler. All other options like in stock.

Download 3.14.1

Make tests for stability.
[Sony Smartwatch 3] Tikerz:
I uninstalled mini launcher at the same time I went back to stock kernel so I don't know if it's causing the reboots or not.
[Sony Smartwatch 3] snake218:
Tested for like 9 hours, mild usage. No reboots so far, working great
[Sony Smartwatch 3] alex6600:
Who use 3.14 version- how about stability and battery life?
[Sony Smartwatch 3] 13ONK:
Been stable since I flashed it, no random reboots. Battery life seems typical.
[Sony Smartwatch 3] alex6600:
Battery like in stock 2-core kernel?
[Sony Smartwatch 3] 13ONK:
Seems like it. I'm a heavy user so I eat through battery. Even on stock I'm lucky to get over 24 hours.
[Sony Smartwatch 3] alex6600:
Stock kernel have 2 cores enabled.

This kernel have 4 cores enabled. It's not bad if result almost same.
[Sony Smartwatch 3] kam33mitch:
With the stock kernel I was getting about 1.75 days on a charge. With 3.14 I've been getting slightly less than 1.5 days.
[Sony Smartwatch 3] lohtse:
check yours apps!!! there are some very battery hungry apps and suspect depending on the kernel config will depend on how much they eat your battery.....
[Sony Smartwatch 3] Momogs:
3.14

I've been using it over the weekend. So far no reboots and battery life is good!
[Sony Smartwatch 3] alex6600:
OP updated with version 3.14.3.

ZRAM subsystem updated to use multistream and LZ4. Number of compression streams set to 4, and compression set to lz4 ( faster than lzo).

Disabled NFS for more free memory.

And implemented some powersaving tweaks.

Note:

Kernels from this version does not break root functionality (if installed).

Feedback is very welcome!

PS. Previous versions are removed.
[Sony Smartwatch 3] alex6600:
OP updated with version 3.14.4.

This version is same as 3.14.3, but with 2 active cores, instead of 4.

Maybe will be more battery friendly.

Try both, and give feedback.
[Sony Smartwatch 3] kam33mitch:
Just giving an apple to apple comparison. The apps I have are the ones I Want/Use. There is no point in getting rid of things that will return my watch to just being a watch.
[Sony Smartwatch 3] murigny64:
Hello Alex6600, 3.14.3 is stable, no reboots on heavy activity. Battery seem to be good (5% per 2h 30 on lite activity).

Ps: i've greenify installed
[Sony Smartwatch 3] lohtse:
was simply advising you that apps may be the cause...I found watchmaker drained my watch 5% an hour but with out it, it dropped to around 1.5%...
[Sony Smartwatch 3] alex6600:
OP updated with version 3.14.5.

Now kernel compressed with lz4 algotithm (faster boot up process).

Disabled unused governors (conservative, powersave).

Disabled HIGHMEM, as our device have only 512 MB RAM.
[Sony Smartwatch 3] mickael91210:
Hello,

Will you provide a full ROM to flash on your LP ROM or have I to use the stock one?

Thanks a lot...
[Sony Smartwatch 3] alex6600:
Is there any need to provide stock ROM with custom kernel?
[Sony Smartwatch 3] alex6600:
If someone want to flash ROM with this kernel and twrp recovery included- PM me. Or I can post link in OP of this thread.

Make separate thread for this does not make sense, IMHO.
[Sony Smartwatch 3] mickael91210:
Yes, it would be easier to try LP or MM and come back if not stable.....

Thanks a lot for your hard work.

I can use a link in OP or in private message, thanks a lot....
[Sony Smartwatch 3] Momogs:
Is the download link down?
[Sony Smartwatch 3] 13ONK:
Dl link in op working for me.
[Sony Smartwatch 3] alex6600:
OP updated with version 3.14.6.

In version- lz4 patches, that I forgot in 3.14.5.

And some minor changes.

As for ROM. IMHO simplest method is restore from PC Companion full stock and flash custom kernel right after restore.
[Sony Smartwatch 3] alex6600:
Currentrly I testing 2-core version, like in stock kernel.

Is somebody interested of 2-core version of this kernel?
[Sony Smartwatch 3] rotor113:
yes , how keeps battery ? There is a difference between the two and four cores?
[Sony Smartwatch 3] alex6600:
It is too early make conclusions. But with UI and typical usage - I don't feel much difference.
[Sony Smartwatch 3] Momogs:
Been running 3.14.6 for just over 12 hours now and battery life is poor.
[Sony Smartwatch 3] alex6600:
Difference between 14.5 and 14.6 minimal. 2 patches for lz4 and enabled highmem.
[Sony Smartwatch 3] mickael91210:
Is it so bad for every one?

Thanks

Battery has been fine for me on 14.4.6, same as 14.4.5, about the same as stock. I get about 24 hours with heavy usage. Also rock stable, I haven't had any reboots.
[Sony Smartwatch 3] Momogs:
Well, my testing window was quite short (12 plus hours). I went back to 14.5 and the battery usage normalised (see attached) and I expect it to be above 2% because I use Sleep as Android at night and it chows battery. I'll re-flash 14.6 and test it for a longer period.
[Sony Smartwatch 3] Simba83:
I would love to get a MM ROM with this kernel included.

I currently use your 5.1.1 ROM and would like to try the MM again, cant upgrade using Sony app. Because i don't have a windows computer in my apartment.

MM ROM: http://xdaforums.com/smartwatch-3/orig-development/sony-smartwatch-3-marshmallow-mec24h-t3382450
[Sony Smartwatch 3] Momogs:
Reflashed 14.6 and battery stable after 29 hours. Will probably get 36 hours out of the charge. Also no random reboots.
[Sony Smartwatch 3] Tikerz:
Working great! No more random reboots!
[Sony Smartwatch 3] alex6600:
Currently I'm testing 2-core kernel. And don't see so much difference in typical usage. Will see how about battery usage compare to 4-core version.

Later I post to OP 14.7 2 and 4 cores versions with some improvements.
[Sony Smartwatch 3] RJASSI21:
I flashed your ROM and was wondering if it comes with this kernel? If not would you recommend flashing this kernel with the rom ive had no reboots since I flashed the rom.
[Sony Smartwatch 3] alex6600:
Rom comes with this kernel. V2 rom comes with root included. Also Rom has 3.14.7 kernel. Later I post this kernel in OP.
[Sony Smartwatch 3] alex6600:
OP updated with version 3.14.7.

Changed mount point options (disable discard), and disabled some unused modules.

Available versions with 2 and 4 active cores.

[Sony Smartwatch 3] foggy69:
The version on the Play Store hasn't been updated for nearly 2 years, so that might cause a problem.

Just to note that the results were the same if I did a full wipe after each kernal change or just rebooted the watch.

[Sony Smartwatch 3] n01z:
I just ran into this issue on Windows 10.. Looking around online shows this is a fairly common problem. The issue is indeed a windows' driver problem, so uninstalling/reinstall might work (it didn't for me).

Here's the fix for fastboot waiting for device:

Boot watch into Fastboot mode, connect by USB to your PC, then..

Follow the steps here: http://www.teamandroid.com/2012/07/3...android-sdk/3/

I literally tried everything online and only found the solution here.. Hope this helps anybody else!!

NOTE: The link jumps to page 3 of a Team Android tutorial for installing ADB/FASTBOOT/SDK. If, for some reason, the instructions on page 3 don't work- go back to page 1 and follow all of the steps, ADB and Fastboot will work. This fix assumes that you are already able to connect to the device via regular ADB ("adb devices" shows your watch).

Hey [MENTION=949860]alex6600[/MENTION] awesome work here!!

Just a quick question- will we be seeing any TWRP flashable .zip files for your kernels??
[Sony Smartwatch 3] alex6600:
If necessary- I can provide twrp flashable zips.
[Sony Smartwatch 3] alex6600:
Somebody using 2-core version?
[Sony Smartwatch 3] Simba83:
Is LCA still better on battery and more stable than MEC.

Or is it time to move on to MEC?
[Sony Smartwatch 3] alex6600:
OP updated with version 3.14.10.

In this version I've included some patches to improve memory related functions.

And revert previous lmk patch to work with swap enabled.

Available 4 cores version for now. I've make additional tests. But still think that battery consumption is almost the same in 4 and 2 cores versions.

Also available TWRP flahable zip (I don't try this, give feedback please).
[Sony Smartwatch 3] kam33mitch:
I have been sticking to the two core versions through most of the iterations as the battery life is a bit better and this is important for me and the 4 cores does not impact my daily use in a positive way i.e. I really don't notice any difference in how I use it. I've been using version 9 since last night and this one has been the best so far. It might get close to two days on one charge for me.
[Sony Smartwatch 3] alex6600:
Who using 3.14.9 for a while- please provide 'dumpsys meminfo' after some time of use.

Thanks!
[Sony Smartwatch 3] alex6600:
Maybe someone suggest app for watch, which can provide access for shell on watch from watch?

That would be awesome!! I don't always have access to a PC for ADB.. Thanks!!
[Sony Smartwatch 3] alex6600:

[Sony Smartwatch 3] RJASSI21:
By shell you mean a terminal command lime right? If thats what you want then you can sideload the normal android terminal app via pc along with a keyboard I did this once. Its fiddly but it works give it a try if you need to.
[Sony Smartwatch 3] alex6600:
Yes. I want using some commands on watch shell, without adb from PC.
[Sony Smartwatch 3] RJASSI21:
Yeah then what I said should allow this simply download or copy the terminal apk for Android from the playstore then use the

adb install c:.....apk command on your pc while your watch is plugged in with debug on then you should have terminal on wear ill provide a link in a moment for a keyboard

Edit:http://us4.campaign-archive2.com/?u=ca045cd04e580f1a87d5b9c63&id=aca556d7a0

It might not be the best keyboard but it works the install command on the post is exactly the same as it needs to be for the termimal if you need files or help ask and ill provide :good:

Hey guys, I'm new to android wear but I have been following this thread for a while now. I recently got my Sony SW 3 and would really like to test this kernel. My question is if it is possible to go back to the stock firmware after flashing the kernel in case of a warranty issue or for future OTAs.

Thanks a lot and keep up the good work! :good:
[Sony Smartwatch 3] 13ONK:
Yup. You can use sonys recovery tool to go completely back to stock or just flash the stock kernel and relock the bootloader.
[Sony Smartwatch 3] 13ONK:
Anyone have problems charging after flashing 3.14.14? Won't charge and pc doesn't recognize it anymore.

I may have damaged my USB port...

stability is fine

performance I don't notice a difference

Sorry, my message was cryptic. I was using 3.14.15 and I am thinking about going back to 3.14.11 as I found it excellent.
[Sony Smartwatch 3] alex6600:
Try 14.15-l.

This is almost the same as 14-11, but more stable and have less unnecessary compiled modules.

Im using the kernel with v2 of your ROM and have been since you released it I get 3 days battery but I have to turn it off at nights and I have had no reboots its also very smooth I think thats perfect for me so I wont be updating it.
