Hello Pablo, thanks for the update i will staying testing and if i find some bugs, i will keep this post updated.
Bugs:
The stock firmware is the one that came with the watch so yes you can upgrade
By stock I mean stock branded firmware.
Not this one.
Stock implies that it comes with the watch.
My advice is to wait just a little longer and I will publish a new version.
Later tonight (for me) depending on your time zone 
Thanks
I reinstalled the firmware that was in the watch as original. Your unofficial new system has a big bug. When you turn on the battery saver, it turns on a black screen with white letters that can’t be cancelled. The watch dies. Or am I doing something wrong
Fingers crossed and waiting for your awesome work 
just please help us understabmd what should we (people that are allready on your version of firmware) do to update
Powersave mode ( black / white ) is normal . Press and hold the power button and turn off
I tried that, but the option to turn off the mode was not there and scrolling through the menu was not possible. I won’t try it again, I reinstalled the firmware.
Since we are communicating, I stopped using google translator and am trying DeepL Translator. How do you display my texts? Is it easy to understand?
if you get into power saving again, there is an easier way to disable it:
So, with the latest update released in the first post (…v9.156.1) my primary concern listed in the above post has been resolved. Namely, the sound notifications for text/sms are working AFTER I turned on the “Other Notifications”. I don’t remember this switch in the earlier release, but then, I’ve been known to have ‘senior’ moments with failing eysight;-) Nevertheless, thank you and the team this resolution.
I’m continuing to use and will identify any issues found with my daily use. Just know, the team working on this ‘unbranded’ firmware are truly in touch with the user’s needs and concerns. Congrats again…
I think the “lift to wake” function is not working in this new firmware version. I have it enabled but couldn’t get to work. May someone test it to see if it just with me, please?
Thanks
We had some issues with the firmware.
These seem to be fixed now, so I will post the updated version soon 
I’ve managed to lock my watch again (LAUNCHER).I couldn’t get to the dial, only to the menu where there is shutdown, restart, etc.
I have the Button Mapper app. I recommend the full version of this app. It can launch the voice assistant and get into the settings. Then all I had to do was uninstall that nonsense.
Wouldn’t it be possible to add a “settings” icon to the restart, shutdown, etc.?
(Long Press escape button)
How secure would that be for those who actually rely on a lock screen to keep their data private…
Thank you much appreciatted
Cool. Thank you
First post updated with legacy update zip for people using stock firmware and a flash tools version for anyone using previous FAW version that may not have the wireless update app included.
Thank you for the update and also for the instructions on how to install it. I couldn’t have done it without it. Everything works, even the battery saver disappeared and that’s probably a good thing. The text of the SMS message still doesn’t fit all on the screen but it’s usable now. If you name your alarm clock the name will cover the control button when you start it, but that’s a minor thing. Mainly if the battery lasts at least from morning to evening with SIM and data activated and a few calls and SMS. Thank you for giving your great work for free to all owners of this great watch.
