I’m assuming you have never flashed a watch before ? Read this
Follow the tutorial but make sure you select " firmware upgrade " in flash tools

You should know that the NVDATA is not a partition that is included in the firmware.
It is a secure, hidden partition that contains the information that is written by the factory.
IMEI
WiFi MAC address
BT MAC address
GPS config…etc etc
How would you not know this but you are flashing stuff on your device…?
This is Android basics…
Anyway, yes the only hope you have is by flashing the entire stock firmware using the Firmware Upgrade option in the flash tool.
Using other methods is dangerous, especially if you don’t what the nvdata partition is…
The good news is that the partition is protected and it is likely going to be ok after flashing the stock firmware.
However, you have flashed lineage.
How did you flash it? (download only, firmware upgrade or format all + download)
Hopefully you did not format all + download when you flashed lineage.
This is important!
Flash the correct version of stock DM100 firmware for the screen that you have.
There are three different types of screen and matching firmware.
Of course, you must know what the original firmware was before you started changing anything right?

ALL+ Download Format. Otherwise it didn’t want to upload. Only by this method it works. Honestly, I have no idea. It is a branded Polish watch. WATCH PHONE ONE PRO PREMIUM. I teset many Roms The best fit for it is the Ticwris Max firmware.
Ah ok.
So you already lost your IMEI and all the other important information by formatting everything.
Well, you obviously did all the research and found out what you needed to do, otherwise no one in their right mind would do something as reckless as that.
By the way, there are a lot of settings and config files in that hidden partition.
Not only imei and Mac addresses, but other parameter files as well.
But you know this already… Right?
So, again I am telling you that you have only one choice of restoring the factory data back to the hidden partition.
You know what firmware you had on your watch when you purchased it - so make sure you get that version and flash it with the firmware upgrade option in the flash tool.
That’s all

And there is a risk of harb bricking the motherboard while flashing (preloader etc). Because I can not use exactly the same firmware but I use Ticwris Max
So do you know what your original firmware version was for the Ticwris Max?
Did you not make sure that you have the original version to go back to if you needed it?
This is always the first thing to do before doing anything else!
If don’t flash the preloader you will not be able to get the NVDATA back.
It’s just not possible, so you have to use the firmware upgrade option.
But you must be sure that you have the original firmware that was installed when you got the watch.
Can you tell me what it was and I will see if I have it.

Yes I know this.
But what is the firmware version you wrote down before you started all this?
When you first got it?

I got it in 2020 in March. It was stuttering terribly for me so I changed versions to Ticwris Max. I didn’t make a complete copy because I didn’t think I would need it. Only later did I find out that the LEMFO T has variations.
Can’t help you if you didn’t write it down.
It’s the most important thing to do in the future. Always make sure you have the stock factory firmware before you start modifying anything

Thanks for the information. I will know for the future. And something serious could happen if I loaded the Ticwris Max system on my smartwach. As I looked at the specifications of the watch in the intruction and other programs it had the most identical parameters to Ticwris Max
@Pixie I think there must be a language problem here because I clearly said that even though watches are identical, three different types of screen and touch panel have been used during the production cycle.
You can’t just flash LEM T or Ticwris Max firmware without knowing what your stock firmware was.
Otherwise you will get:
- lines across the screen
- half a screen
- no touch response
Do you understand what I mean now?
@Pixie just out of curiosity, what year were you born?
Was it in the 80s, 90s, 2000 - for example?
I’m doing some research.
Don’t worry about it if you don’t want to say… No problem
2000 years. About these touch problems I know. I just had a problem with the touch and a gray screen. That is why I wrote to you that ROM Ticwris MAX works best. My question is this. From the beginning since I’ve been using the watch when using the screen for long periods of time, there will be these burns on the screen like plasma TVs have, only they are very visible, but after a few minutes they disappear. What could this be caused by. I had this immediately after buying a smartwatch.
“My question is this. From the beginning since I’ve been using the watch when using the screen for long periods of time, there will be these burns on the screen like plasma TVs have, only they are very visible, but after a few minutes they disappear. What could this be caused by.”
Normally by using the wrong firmware or by forcing the screen to stay on all the time.
I have both DM100 and DM101 and have had no issues with both…
Sorry but I can’t explain your issues because it seems that you have been doing all sorts of things and still - you don’t know what your original firmware version was … 
The problem occurred when I had it on for 30 minutes or the screen is very bright
Protect2 :Data will be lost
Your problems are exactly the reason why we privatized this topic. I don’t want to imagine solving these problems for 200 members.

Which firmware are you downloading now and getting this error?
You are using stock A7.1.1 firmware now?
As I suggested, to get your imei back?
If you are trying to flash the DM101 firmware again then you will get an error. Because it is not for DM100.
Protect2 is the nvdata partition that you probably wiped when you chose format all + download to install lineage.
