You might have to downgrade to the version you were using before. Older phones just don't run well with newer Android updates

So I have a few questions about the android P beta program. I was wondering if anyone could answer before I opt into it
1) if I opt into I get ota updates which won't be Verizon variants so would I be able to jump back to Oreo?
2)would this allow me to unlock my bootloader possibly?
1) You should be able to go back to oreo by opting out of the beta and taking the subsequent ota from Google. Or you can manually flash a newer ota you downloaded from your computer. Must be a newer build than the the one you are on.
2) Almost certainly not. Unless there is some error, your bootloader will not be unlockable. You are not currently receiving "Verizon" builds. No such thing. Your device info is on a server side whitelist / blacklist. It has nothing to do with the build you have installed. That is my understanding.

Im not sure i understood this properly, I've already unlocked the bootloader of my Verizon pixel 2 on 8.1, if I update to P, will the bootloader be locked back? Or I can update and still enjoy the unlocked bootloader?
Thanks!

If you unlocked the bootloader already, it will stay unlocked until you lock it via fastboot from your computer. Flashing firmware will not relock it. Don't worry, updating to Android p won't mess with that.
I'm really enjoying this beta so far. The new navigation gestures are cool. Nothing so far that makes me want to go back to 8.1.

What version of magisk are you flashing? You should be using the beta magisk. Looks like people are having some success rooting with version 16.4.

That's correct. Just checking. You need to boot to twrp to flash magisk. There isn't another way that I know of. Maybe download twrp img again? I doubt its a corrupt download since you get the twrp splash screen, but its worth a try.

You can boot into the OS right? Are you're platform tools the latest version?
Reverting back to oreo, rooting, and updating to p beta will either fail or wipe out root. You won't end up with p beta and root. Don't do that.

You can't flash any version of TWRP. It has to be made specifically for the NEX S using their source code, which is currently closed.

by the way, without unlock the Bootloader , you can do nothing with vivo phones. maybe you can use aftool force flash a unofficial recovery but you can not get in the system

Hi Bro, try, only android 9 to android 8 you need other procedure.
It works... If bootloader is unlocked.
I have done it countless times, to check what is causing the volte problem.
Yes you can do it with stock recovery, because it doesn't matter!
You have to download fastboot rom, (download 10.3.3.0 or 10.3.5.0 if you want dual 4g option) (do not download recovery rom)
Extract the .tgz fastboot rom file and place it in your desktop folder (if you place it in any other folder, it may cause location not found error.)
enable usb debugging in settings and enter fastboot mode in redmi y2/s2 and connect to pc.
Launch mi flash in your PC, click select and select extracted rom folder, then click refresh.
@THE bottom right corner, Change option to "clean all"
Then click on flash, reboot when complete.
If volte doesn't work, flash baseband firmware via fastboot!
Gud luck
Hello , my xiaomi 12 has just lost imei and unknown baseband , does anyone know how to fix it ? Previously I have tried flashing to the enginering rom and doing the fastboot erase modemst1 command but it hasn't worked either, please help
If the bootloader is unlocked, use Miflash with the same rom that was on the phone when it was purchased.
