Android 11 Z40 models (LEM16, Lokmat APPLLP + Unbranded etc) and Firmware v1.6 OTA/Update issues

Hi all,
With the message owner’s permission I have made this public.
There were many issues here and this was before I found out that the 1.6 FW could not be down graded to any pervious version once flashed.
Cheers

Which version are you trying to flash?
Is your watch a Lemfo LEM 16 or Lokmat or generic Z40…?
Which drivers have you installed?
What version of flash tool are you using?
What version of Windows are you using?
Can you show me the complete file path to the pac file in the firmware folder?
Does your antivirus software have any logs regarding the use of the flash tool?

Did you install the drivers using windows driver signing disabled in advanced startup settings?
Windows can be annoying with unsigned drivers.

The screen you show here -

This is the pixart BT and sensor stack firmware updating - or trying to.
This is failing - it could be that your image is corrupt.
You should use 7zip to extract.

Which firmware version were you on before this happened?
It seems to be trying to update to a much newer version of Pixart firmware in your photo.
Can you boot the device at all and make a factory reset?

– Im Extract with 7zip all done, nothing problem…
The Initially from Buying the version v-1.6, but my experience about this camera device upside down at Videocall Whatsapp…

Sir,… Can I Reset Factory? i cant running the system, i cant access setting in Menu

So, it is refusing to allow you to down-grade the pixart chip firmware.
I have not seen this issue before.
We can fix it by flashing v1.6.

I am discussing this situation with the Chinese branch of the firmware provider.
I will find out what the reason is for downgrade failure.

Do you want to go back to v1.6 so that the watch will work again?

I spoke with my partners in China and we think going back to v1.6 should make the watch usable again.
Because the Pix firmware will not need to be updated.
We are looking into the reason why your watch is like this.
This is the first time we have heard of this problem.

Do you need the v1.6 firmware?

Yes sir… im need v1.6… thanks a lot…
Im waiting for firmware v.16

First time my device arrived with this firmware

I have sent you the download link.
Let me know if you download it ok :ok_hand::+1:

Excuse me, Sir…
I’ll Try again with Firmware v.16 have you send to me at google drive… but the result same as before…

Any solution, Sir…
Now… I don’t know what to do. :smiling_face_with_tear:
