Tool Description
1. The tool is based on a modified version of AmazfitBipTools, thanks to the original open source .
2. The tool supports unpacking, packing of the official watch face bin file.
3. Mi band 4 supports 16,581,375 colors.
4. Mi band 5 supports 15,499,008 colors.

How to
1. Unzip MiBandWFTool_X.X.zip.
2. Download .bin file from catalog or get standard watchface file.
3. Drag the .bin file to WatchFace.exe (in step 1. , get the decompressed file)
(if there is only one log file, the decompression failed).

4. There are two ways to modify the dial.

• is to modify the corresponding image file and replace it with what we want.
• is to modify the corresponding json file and modify the position of the image.

5. After all the modifications are completed, drag the modified json into WatchFace.exe in step 1 to get the corresponding bin file
(the file name depends on the name of the bin. If the .bin file is not generated, the package is wrong)

6. Copy the newly generated bin file to the corresponding directory of the mobile phone, and the synchronization will be completed. (This step is not very clear, you can refer to the original tutorial) above, you're done!

How do you synchronize bin files larger than 300kb to the bracelet?

You can't, that's why the PalleteImage version of the Tool is very interesting. Because with that tool you are supposed to get lower size bins altought you get poor quality.

But as you can read in my earlier messages, there seems to be a problem with the tool and the images compressed are not shown in Mi Band 4.

I am waiting for the author of the tools to have a fix for that

Yes, I saw someone uploading a dial file larger than 300kb. I wonder if someone can actually brush it in?

I think you should post your entire project to the cloud, we will help you

[lukbe]

@lukbe Please provide files, i will verify)

please swap in json
Activity <-> Date
its wrong position thats why he skip it on miband4

I did change, however situation is still same. Gif looks good, after loading bin in to MB - weekday is not displayed.

[lvpokka]

looks like its different type of storage and Palette now is not supporting transparency...
Please use real colors for (fake)transparency to match background color! there is only chance to use good quality with low resolution palette image.

[DarkForgotten]

Completed!
I have renumbered all the pngs and edited the json, this have solved the number issues.
Created new pngs for hours and minutes, use the same for both created some conflicts.
Added the 21 chinese pngs for week day and added 7 for italian language.

Now it works! Thanks for the help.

Yeah thank you for your time. I knew that where was some false values. I tried to understand what some json values do.
I thought the "BottomRight" etc. wasn't necessary, because "TopLeft" theoretical seems to be enough.
I still don't understand what is X2,X3,Y2 ???

I also copy and pasted your json example but i still get false rendering.
And what tool do you used for the screenshots? Selfmade?

[lvpokka]

[mention]Anonymous86[/mention] check if all images are used! you should not have unused resources
+ tool from screenshot is rebuilded from amaizfit wf editor on JS

[Anonymous86]

[mention]lvpokka[/mention]
Yeah thank you very much. I forgot one index.
What do you mean with "JS" ?

I changed transparency at weekday and situation is still same. After loading WF in to mi band, week day is not displayed.
I always use type of compilation: RawImageMode

I have test this version with images without any transparency, and it still doesn't work.

The watchface in the miband is all black, can't see anything.

[lukbe]

I think that for MB4 must be always loaded 21 weekdays (7+7+7). In the case when I load only 7 pics, on the Mi band is not week day displayed - I tried to change language of the MB4 to Chinese, after this change was my pic displayed...

[kry008]

Can someone describe this tool?

[lvpokka]

[mention]kry008[/mention] read topic "How to"

[lukbe]

Will you create a graphical application?

Or exist app for live view of the json file and possibility to edit this file? Something like app on this web page for cor and bip.

Thank you

[lvpokka]

[mention]lukbe[/mention] I have modified it, but it's working partly, I updated it only for json debug. Don't want to make it public and then answer on allot of questions

[lukbe]

Can you send me a link to this app?

[Turko9999]
