have any concerns about features included in this ROM before flashing it! 
YOU are choosing to make these modifications, and if you point the finger 
at me for messing up your device, I will laugh at you.

Thanks @alex6600!
Just factory reset, and downgraded from Marshmallow, to this ROM.
All is working well so far!

I honestly tried to use Marshmallow. Compiles kernels dozens of times. But no luck.
Reboots and lags does not suit me.
And decides to use 5.1.1, as more stable.

I'm all about this ROM as Marshmallow has just been one big rebooting mess!
However, during flashing everything went fine except the build.prop install...

Your line:

mount("ext4", "EMMC", "/dev/block/platform/sdhci.1/by-name/system", "/system", "max_batch_time=0,commit=1,data=ordered,barrier=1,errors=panic,nodelalloc");

Fails saying device is busy, or is not ready...???

Did you mount system in twrp before install?

I got it sorted out actually, turns out it was because I was using the version of TWRP I got from here:
http://forum.xda-developers.com/sma...24h-twrp-root-busybox-kernel-adiutor-t3365990
I initially skipped installing the one you provided above because I already had that one installed, but switched to the one you provided and reflashed with no errors!

One last question, is it possible to turn off the rounded screen corners? Is that something that can be edited into the build.prop or is it in kernel?

Rounded screen corners is a kernel feature, not ROM.

And do you recommend your LCA43 kernel from here http://forum.xda-developers.com/sma...ment/kernel-sony-smartwatch-3-kernel-t3304102 or should we stick with the one already in the rom? Or are they one and the same?

Rom include kernel v. 2.22.
Today I posted 2.23 in kernel thread.

Hi everyone, could someone please help me? I'm trying to downgrade my SW3 from MM to this rom, but I don't know how to do it. I've got installed windroid toolkit but it doesn't anything. I can't install twrp, unlock bootloader... nothing. I've got correctly installed ADB drivers, windroid recognises my watch, but this is everything I can do until here. I'm trying to do the downgrade because my battery flies twice per day, meanwhile in MM battery lasted up to 4 days... Has someone the same problem?

Reboot to Fastboot, and flash the TWRP .img from there. (note: be sure you are in the directory where the twrp.img file is stored)

adb reboot bootloader
fastboot flash boot [I]twrp.img[/I]
fastboot reboot
adb reboot recovery

And viola. You can then flash this ROM.

Do you plan feature 6.0.1 update? What are benefits over stock...?

adb reboot bootloader
fastboot flash boot [I]twrp.img[/I]
fastboot reboot
adb reboot recovery

And viola. You can then flash this ROM.

Thank you for your help, but unfortunately my watch didn't pass the white screen saying fastboot. PC was saying "waiting for device" for so much time. Am I doing something wrong?

Hello and thanks for the command lines.
I want to try it because my battery drain is too high with MM and kernel 3.10.1 (but no reboots).

But .... How can I use the virtual SDCARD? How do I have to do to put the zip file in this SD? AFter, I think it will be ok....

Thanks.

It's OK actually, just after twrp flash, I have "VIRTUAL SDCARD" on my windows pc, I put the zip and I flashed it in recovery.

Thanks

When the watch is connected to computer, type:
adb push rom_file.zip /sdcard/Download/
This command will copy ROM to /sdcard/Download directory.

More excellent work! Will we be able to root this (i.e. flash supersu.zip in TWRP)? Also, I can't seem to access the files (ROM.zip, TWRP.img), is the site down?

Webserver was in the planned maintenance. Now everything is working as it should.
SuperSu work fine. You can download SuperSu_2.46 here
