4.Flash Magisk 19 If you want root.
I Recommend custom kernel for OOS PIE made by @mcdachpappe link to thread: https://forum.xda-developers.com/on...-development/kernel-renderzenith-mcd-t3838788
Then you can Reboot and Enjoy your Pie Rom. It will Boot up Much Faster.
Proof:
1. From custom rom pie to OOS PIE

What does the zip file do ?
And does the internal storage stay if i didn't flash magisk?

This zip contains bootloader of 5.0.8 but modem of pie rom . And internal stays like usual if you don't flash magisk. But it's always good to flash magisk if you want to use apps that require root.

Actually i don't need root.
Because of that my banking apps don't work.

Without root it will work fine too.

Does this method work on a custom pie rom?

 

[Rafeh]

Yes

 

[Rajesh_m]

Yes

Are you sure? Heard flashing on top of custom pie rom may cause some issues.

Work on encrypted device ?

 

[Rafeh]

Yes

Your proof video really needs to be made properly. First, you are flashing it on top of a pie rom. Second, you are flashing a custom Pie OOS beta ROM.
What you can do is, you can roll back to OOS 5.0.8 stock, show that your phone is encrypted, then go on to flash original Pie community beta zip, then your firmware and then boot it up.

Ok, so this was a custom pie build of community beta. I thought this could be done with the official custom build. Thank god, i was about to flash official community pie beta on top of custom pie rom.

I tried this method and I have been stuck on boot for over three hours. I am going to roll back to official OOS 5.0.8 then perform the upgrade.

@op

Your step 2 is confusing. This isn't the official community beta you flashed as per your YouTube video.

I tried on official community beta too its working, the reason i am using this rom (https://forum.xda-developers.com/oneplus-3/development/rom-theone3os-v1-0-ob37-v1-0-5-0-3-t3798911) is because i can debloat some unwanted apps and flash custom kernel.
on Official community beta you cannot flash Custom kernel because of not enough free space.

So you are sure this method works with official community beta too on top of custom pie rom?

 

[Rafeh]

Yes 100% sure

Also i saw you didn't selected the option no-verity. Were your device encrypted? Mine is decrypted though.
