[Huawei Mate 20 Pro Themes, Apps, and Mods] vPro97:
In earlier EMUI 9.0.0 we had the option to change the fingerprint unlock animation. This option was later removed and hasn't come back.

Inspired by the thread for the Huawei P30 Pro, I investigated whether it was possible to change the lockscreen fingerprint icon of our Huawei Mate 20 Pro - and I successfully managed to. Huge thanks to [MENTION=3462957]zimmen[/MENTION] for discovering this for the P30 Pro and providing the links and files. Make sure you thank his thread as well.

This guide has been tested and works for the Huawei Mate 20 Pro! You will not be able to use the animations provided in the P30 Pro link.

Use the theme provided at the bottom of this thread as the base of your modding. The theme is the Huawei Mate 30 Stock theme with modified fingerprint icon (OnePlus) and the 'Color Swirl' animation:

To apply the fingerprint animation provided

Download the theme and extract the file 'Painted Planet.hwt' to 'Huawei' - 'Themes'.

Return to your app drawer, open the 'Themes' app, navigate to 'Me' in the bottom right corner, 'Themes' and apply the 'Painted Planet' theme. Reboot for the fingerprint animation to take effect.

Now, in order to change the fingerprint icon:

Download the theme and extract the file 'Painted Planet.hwt' to 'Huawei' - 'Themes'.

Search Google for the app 'MT Manager'. This is a file explorer that allows you to decompile and recompile apks on the go.

Open 'MT Manager'

Navigate to 'Huawei' -> 'Themes' -> 'Painted Planet.hwt'

Open com.huawei.aod, then open 'res' and 'drawable-xxxhdpi'.

Find a picture that you like as the fingerprint icon with the approximate size 220x220 pixels. The file must be '.png'

Make four copies of the same picture and rename them to 'ic_fingerprint_1.png', 'ic_fingerprint_2.png', 'ic_fingerprint_3.png' and 'ic_fingerprint_4.png' respectively.

Using MT manager, move the four pictures into 'Huawei' -> 'Themes' -> 'Painted Planet.hwt' -> com.huawei.aod -> 'res' -> 'drawable-xxxhdpi'.

The manager will ask you if you'd like to replace the files, tap 'yes'.

Once you've moved the files back, swipe back untill you get a confirmation that you would like to save the changes to the com.huawei.aod file!. This is an important step!!!

Now navigate back to your app drawer, open the 'Themes' app, navigate to 'Me' in the bottom right corner, 'Themes' and apply the 'Painted Planet' theme. Reboot for the fingerprint animation to take effect.

In order to change the fingerprint animation:

Find an animation that you like. The size of each frame must be 600x600 pixels and the centre of the animation must be a cyan blue circle (approx 220x220 pixels) for the fingerprint reader to correctly read your fingerprint.

Note that the fingerprint animation only supports 12 frames, each frame mut be in '.jpg' format and named 'wave_600x600_black50_01', 'wave_600x600_black50_02'... etc. through 12.

Once you have your 12 pictures, use MT Manager to move them into 'Huawei' -> 'Themes' -> 'Painted Planet.hwt' -> com.huawei.aod -> 'res' -> 'drawable-xxxhdpi' and replace the already existing 12 files wave_600x600_black50_xx' with your correspondingly named pictures.

Once you've moved the files back, swipe back untill you get a confirmation that you would like to save the changes to the com.huawei.aod file!. This is an important step!!!

navigate to 'Me' in the bottom right corner, 'Themes' and apply the 'Painted Planet' theme. Reboot for the fingerprint animation to take effect.

FAQ
