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!

The problem is as stated by the program, tat your image uses too many colors for palette mode, the palette size has to be decreased. To do so, the simplest way is to convert the images with "too many colors" (the index is named in the error) to an indexed image and then back. Use programs like Photoshop/Gimp or online-tools.

[mention]MonsterDruide1[/mention]

Thanks! I was doing some trial and error and managed to get it working in a similar way you described. Except I used the posterize feature to change the image instead.

I still don't understand the part about raw.cfg though. But since I got it working I'll just stick with it.


[mention]lazimk[/mention]
I completely missed your response earlier because of all the new posts since the last time I checked. Thanks for that advice.

Funny thing is. The watch face that I made some adjustments to and am currently using is one of yours. The Samsung Galaxy Active Bloodred WF. I changed the months to show letters instead of numbers. Thanks for the great work creating it.

[lvpokka]

Tomorrow will be new version release.
- Added image Quantization algorithm, it will compress image if it will have too much palette colors.

Hope no one will use Raw wf builder)

This is probably a slightly strange one, but I think I have found a bug in the compiler that prevents animations from working as intended - From my experiments, it seems that watch faces with a second hand are unable to run animations and will instead leave them static on the first image in the series. Has anyone else found this an issue or a workaround for it? I have attached a working copy of my watch face where animations do not work as intended
Thanks

[lvpokka]

speed should be 5 or more, thats my testing. maybe another parameters will affect somehow

btw Seconds now working fine!

I had read that second hand and animation cannot co-exist in MB4 WF, long ago. i never tried this.

Thats great!!
i hope it will fix preview with respect to animation repeat count.

Sad news is Mi is not supporting custom watchfaces in MiFit app. also trying to prevent it by firmware update :'(

[lvpokka]

[mention]lazimk[/mention] its uploading with custom apps like MibandMaster
seconds now working
and yes also implemented for you repeatcount 1))

[lazimk]

[mention]stqcb[/mention]
thanks.
it will be great to see version with month names

[lazimk]

[mention]lvpokka[/mention]
Thanks bro for new update!
Yes we can upload. but i heard some WFs are not working as indented in MiBand with new FW

[lvpokka]

send them to me) i will check them.

@Dario i have more then 5 testers which is creating watchfaces on daily bases) could you explain where you have bugs in 1.3.9(better than 1.3.8)

I unpacked the .bin file using the "WhatchFace.exe" application (inside the "PaletteImageMode" folder), then I replaced the .png images of the days with the .png images of the days in Italian (created by me with Photoshop ). When I completed the changes I repeated the procedure with the .json file via the "WhatchFace.exe" application (always in the same folder), and it did not return any .bin (new) file: only .log file, the image of the dial, and the gif.
Doing the same procedure with the application, in the "RawImageMode" folder, instead, the new .bin file fails to synchronize with the bracelet.

@GIK-Team where is it possible to find version 1.3.8 ?
I have read that it is the best version (I have already tried other versions and other modified programs but they are full of bugs )...
I wanted to change the days (replacing them with those in Italian) in the bluegreen whatchface of @lazimk ...
Thank You
Bye

I will use this version, thank you very much !

[stqcb]

@stqcb
thanks.
it will be great to see version with month names

[mention]lazimk[/mention], here's the .bin file with the modifications. This is my first try at modifying a file and still don't know exactly what all the json parameters mean so hopefully I did everything right. It seems to be working on my mi band so far.

[lvpokka]

New info,
Animation work BAD with palette mode, please use raw mode for animation
(probably animation and seconds also not working)

I just can't ...
I also reduced the weight of the images of the days but nothing ...
And then it is strange that the new .bin file weighs twice as much as the old one (more than 400 Kb) ...
How did you get there ??!!
Can I send you the images of the days I created, so you can create the .bin file yourself?
Thank You
Bye

Hi guys, after latest firmware update (V1.0.6.12), animations seem to not work anymore

Moreover, there is a problem with the WF's upload using the Android app, custom WFs do not appear anymore.

I tried both with my custom WF and some created by other users, like this https://amazfitwatchfaces.com/mi-band-4/view/6045

UPDATE

I found all the answers here: https://www.reddit.com/r/miband/comment ... atchfaces/

"Animations work, just not when they are too slow (animation speed must be at least "4" in the json file)."

[Maikeldevil]

Can anyone tell me how to set speed on an animation? My animation is running to slow:-( any ideas?

[Tofuman89]

On the new firmware, there is a weird behaviour if there is "seconds" variable in the .json file of the WF. The seconds of the watch will be animated for the new firmware but everything else such as the steps, date, weekdays, calories, distance, heart rate will be hidden. For example is in this WF: https://amazfitwatchfaces.com/mi-band-4/view/1853 . My day to day custom WF is now somewhat broken because of this bug. Does anyone have a workaround? Thank you

This information actually came from this forum viewtopic.php?f=62&t=797&start=50

It was suggested to use at least 5, but 4 was working in my attempts.

Unpack watch face, edit json file, find ""Other": { "Animation": { "Speed": 4,}}

Is there a way to create a watchface that displays time in words instead of numbers? Like it says "ten" instead of 10. Thanks n advance.

Yes, there is. But it will take a lot of space.
