Yes, I see.
That is the way that firmware works.
Have you tried the international firmware unbranded? It’s up to you but it works fine without a Sim card
Rather not. i don’t know how to install it
And why without a SIM? I bought them mainly because they have a SIM card. Outside of work, I use them instead of the phone
Why not give it a go ? We can help

Good luck . There are lots to read on the forum but many make it harder than it actually is
I know, the computer is not a problem for me, not the phones either, but I don’t know the smart watch yet and I’m also 57 years old … 
No problem. Some of them are older than you. And actually your smartwatch is a smartphone. Strictly speaking…

There might be an easier solution available soon, that allows an ‘OTA’ upgrade from the local storage.

Wow, that’s exciting news 
I tried unofficial firmware, but I can’t. The ZIP package contains files other than those listed in the manual. Even so, I managed to run the installation. (I installed the drivers and restarted the computer) But I can’t find the file “MT6739_Android_Scatter”
Did you say M6739 ?
That is the LEM12 not the LEM 12 Pro.
Do you have Android 10 at the moment or Android 7.1.1 ?
It sounds like you have a LEM12 because it uses M6739
phone information in settings:
Model LEM12Pro
Android 10 system
Build number Z32-LEM12pro-V06_20201102
AIDA64 also shows the LEM12Pro and Hardware MT6762 Platform MT6765
I’m from CZECH REPUBLIC but it probably doesn’t matter
the tutorial was made for another watch, so you can’t follow it blindly. MT6739 is the name of the processor that was used in all the android 7 watches except the few first ones. the android 10 watches uses the processor called MT6762, but the scatter file is named by MT6765, so for the lem 12 pro the scatter file will be named MT6765_Android_scatter.txt

He’s not there either. I do not get it.
You have to download it from the top post.
Unzip it, you’ll find the scatter file inside.

I have it. The file is there. Thank you
Sorry to bother you all the time. Does this unofficial firmware also contain czech language?
čeština?
Yes it is included. It even contains languages whose existence was completely unknown to me. It’s the most extensive language library I’ve ever seen on a smartwatch.
