[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] girish17m:
This is the perfect setup for android p, I use this as my daily driver and it has NO issues as of now. I have gone through almost a whole week of testing each rom before I chose this combination and this is super stable IMO.

Steps Followed:

1) Take backup of whole device (Including internal storage)

2) a) If you are on a Non-Treble rom:

- Install factorytovendor.zip (https://androidfilehost.com/?fid=962187416754475515)

- Install treble TWRP recovery img (https://www.androidfilehost.com/?fid=5862345805528044154)

- Reboot to new recovery

- Proceed to step 3

b) If you are already using a Treble rom:

- Proceed to step 3

3) Completely wipe your phone (Including internal storage, I found that this gives the best result)

4) Reboot to recovery (you will get no OS installed screen, slide the icon and do not worry you will reboot to TWRP)

5) Connect your phone to your PC and transfer the following files to the internal storage:

a) CR droid treble ROM (I used this: https://androidfilehost.com/?fid=5862345805528059385)

b) Img file extracted from P-DP5-sGSI-Aonly.zip (you can find it here: https://androidfilehost.com/?fid=5862345805528058112)

c) POST-sGSI_1_v0.14.zip (https://androidfilehost.com/?fid=5862345805528063582)

d) POST-sGSI_2_v0.17.zip (https://androidfilehost.com/?fid=5862345805528063581)

e) POST-sGSI_3_v0.2.zip (https://androidfilehost.com/?fid=5862345805528058103)

f) dp5-lag-fix.zip (https://drive.google.com/drive/folders/1_UOASaZTlclwANdfVPxZVqLoqStOJ2wE)

29) after 10 minutes, try registering your finger print:

a) if it passes, YAY!

b) if it goes back to previous screen, click on continue and try registering (no need to wait for 10 minutes)

c) if it goes to register screen and fails, YAY! you can set it up after the setup is complete (don't worry, it will work)

30) If you are restoring a backup from the cloud, the restore app will stop responding, dont worry. Click on app info and grant all permissions to the app, go back to previous screen and try again, It will work.
