This worked nicely. Actually easiest rom there is to flash. Super simple for complicated people. Ended with no data though. Only have A11 on one side. A10 is still on slot _a and broke data. But I'm working on that part.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] mattie_49:
Just wanted to simplify this process of install for everyone having trouble. Download latest for your device with image in the name. I put it in an empty folder on my desktop; don't unzip..Renamed pa.zip. type cmd in address bar of folder and open your cmd prompt here. Reboot device into bootloader. Run command "fastboot update pa.zip" when it completes boot into recovery and wipe data,factory reset, simple method for complex people. I just couldn't quite understand . Hope this helps someone as I struggled with for days. I tried side-loading and fastboot flashing through fastbootd. Both my ways failed. I'm gonna try to look into build and see how this magic works through fastboot, as it's the only one out that installs in this fashion..

There is a beta 3 that came out 2 days ago. Newest is best. Beta 3 dated 2/7
[OnePlus 8 / 8 Pro & 8T Cross Device Development] FoxyDrew:
What am I missing? I'm having the same missing system partition error, what's the difference between the "pa-image.zip" and "pa-zip" I'm using the Oneplus 8, and I'm only seeing one zip file (for beta 3, the version I'm trying to flash obviously as its the latest)

I see that in that directory there are *vXXX*.zip files and then *vXXX-signed-image*.zip files. But they are for beta1 and beta3 respectively.

I'm supposed to flash beta 3 in fastboot, wait for the system error, then sideload beta 1 in recovery? I don't get why that would make any sense.

Edit: Exact error when trying to "fastboot update pa*signed-image.zip" or trying to unzip and flash manually

boot, recovery, and dtbo flash just fine. I tried flashing those first and the rest in fastbootd, got the same error. Flashing to a specific _a or _b partition also not working. Also tried MSM and repeating failed steps.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] angelmakumbe:
OP8 Pro. I flashed PA beta 3 with OOS beta 6 and camera is not working as it should. Video recording fails and with google camera apk, the frames are always less than it should.

OP8. Idem but with OOS beta 5. All is working perfectly.

@ZVNexus Could be OOS version the issue?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] sefai77:
How you can flash 8pro. i am trying long time but cant flash. Which method did you use and which stock rom did you install on ?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] angelmakumbe:
You can read beta 6 in my post.

Just fastboot update pa.zip and format data after the crashdump
[OnePlus 8 / 8 Pro & 8T Cross Device Development] sToRm1nG:
Be aware that this is not yet officially released. If you use it as a daily driver stick to Beta 2 until Beta 3 is officially released. This is most likely not the final build.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] ZVNexus:
I don't do any testing with Google Camera, only Snapdragon Camera and Camera2, its an unsupported app.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] hammeru:
Just trying to decide if I want to buy a One Plus 8T Pro or go a different direction. Still on a rooted LG V30 daily driver that works great, but looking for a better camera.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] enjoy_life:
How's Snapdragon Camera in terms of shooting videos? Is EIS and OIS fully supported? Is the bitrate/quality selectable?

Edit: ok I flashed the ROM myself and wasn't thrilled by the snapdragon camera
[OnePlus 8 / 8 Pro & 8T Cross Device Development] KokkoM:
After a week use beta2, im sure i never go back to stock.

This is awesome and pretty stable too for daily diver.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] nyzoli72:
i'm on latest oos stable on op8pro , if i want to flash PA what is the perfect way to do it? i read all forum but it is too chaotic to me. need a step by step instruction. i'm downloaded the latest beta 3 zip file for 8pro.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] KokkoM:
Dont use beta3, take beta2.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] nyzoli72:
is it buggy? but ok, i will if i get a good way:)
[OnePlus 8 / 8 Pro & 8T Cross Device Development] KokkoM:
Its not officially out.

Beta2 is very stable/good everyday usage.

Download the latest fastboot zip we released (hint: it has an -image appended to zip name)

Reboot to bootloader.

Flash the fastboot zip with "fastboot update pa-*-signed-image.zip"

Reboot into recovery after it is done flashing & wipe userdata.

It maybe ended to crasdump mode dont scare, just reboot to recovery and do factory reset.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] nyzoli72:
thanks a lot, now i booted so start set it up.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] USMC-4life:
It's in the original post. I know the rest of the thread has lots to read, but OP is the most important. Shows where to download and how to install. Happy you're up and working though!
[OnePlus 8 / 8 Pro & 8T Cross Device Development] nyzoli72:
i know that but i was unsure about that because on other custom rom is different. One more question, the aod is ok with burn in protection?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] pakom8:
Im on beta6, can i install on this version?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] FoxyDrew:
Can someone try to help me out? Coming from stock OOS11 I flash this per the instructions in OP. Then wipe data in recovery.

Every time I boot the ROM it boots successfully and I get about half way through the Android setup, then the whole screen goes black with the message "Rebooting to recovery, Factory Data Reset". Recovery gives me the error "Cannot load Android System, your data may be corrupt.

This problem persists if I try to wipe data again. I've tried beta 2 and beta 3.

Edit: After like 10 tries, I found the (very small and weird) issue. You HAVE to set up a wifi network in the Android setup. I usually never do to avoid the Google Activity prompt and the install 3rd party apps prompt. But after doing the same exact thing 10 times in a row like a crazy person, and only getting halfway through the Android setup, this fixed it for whatever reason. Ill try and grab a log right now and post it.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] mattie_49:
I always had the same issue as well and I do indeed skip wifi set-up to rush through and see if I have data. Because nothing custom has had data for my variant. Cool bit of info. Thank you. So I actually have never had this up and working past the rebooting recovery error to factory reset. So I actually have never known if I can even aquire data. Good to know. I'll try again later this evening cause it always flashes perfectly with no errors
[OnePlus 8 / 8 Pro & 8T Cross Device Development] dlads:
To anyone having issues with the camera, when I had CRDroid and PEx installed I used two.

FV camera and Camera pro X.

Think they're both premium but you can try both, they offered a lot of options I simply didn't get with the stock ones.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] nyzoli72:

[OnePlus 8 / 8 Pro & 8T Cross Device Development] nyzoli72:
how can i update it from beta 2? i tried from fastboot but it failed

tried sideload and it failed too
[OnePlus 8 / 8 Pro & 8T Cross Device Development] dlads:
Is there a changelog / bug list anywhere for this?

Also the OP still says beta 2.

Brilliant that this is still being worked on, still haven't flashed it but I'm getting a bit bored with OOS.

Would be great to know what's working or not before committing.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Raylon00:
Got Beta 3 to install on 8t. Had to edit the android-info.txt inside of the zip file. It said target board was "kona" which threw target errors in install process. After changing board to OnePlus8T, installed fine with update command in fastbootd.

Change txt file

Re-zip Rom with new txt file

Reboot to fastbootd

>fastboot update ROM.zip

Wait

CRASHDUMP

reboot phone > It prompts for Factory Reset

Rom seems really quick. No problems so far while installing apps and changing settings. I used previous advise to connect to wifi during setup to prevent problems.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] mattie_49:
Try and try again with every update. Rom just continually tries rebooting into recovery to wipe data after I've already wiped data. Makes no sense. Maybe I do need A11 on both slots because this behavior is after everything flashes without errors . But A10 is still on slot_a. I'll try again after Verizon throws a security patch my way and puts A 11 on both sides.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] scott45333:
I would recommend putting A11 on both slots. I have never had an issue with this rom.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] dlads:
You'd need Android 11 on the slot that you're using.

It's just easier to have it on both..

Least that's how I understand the slot system.

Every major update it switches, so in theory you could have switched active slots after your installation.

Or just do as @scott45333 says and either fastboot or MSM Android 11 then go from there.

It just works that way
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Lunchb0ne:

i got this with beta 2 also but i had to adb sideload afterwards an it works

whats wrong with my try?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] MariusKv:
Download the latest fastboot zip we released (hint: it has an -image appended to zip name)

Reboot to bootloader.

Flash the fastboot zip with "fastboot update pa-*-signed-image.zip"

Reboot into recovery after it is done flashing & wipe userdata.

This is easy
[OnePlus 8 / 8 Pro & 8T Cross Device Development] spoeckes:
thanks allot for your reply.

i did exactly this way, after "fastboot update pa-*-signed-image.zip"

the files will be excracted, after this they will be flashed.

at this point i get a random errors that the partition does not exist, got this one time when flashing system, the other time on flashing dsto. after flashing and getting the partition errors sometimes oos boots up with wrong dpi and a lot of erros , somtimes it doesnt boot at all

i allways used msm before und bootloader unlock
[OnePlus 8 / 8 Pro & 8T Cross Device Development] MariusKv:
Are you on the latest open beta before flashing?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] spoeckes:

[OnePlus 8 / 8 Pro & 8T Cross Device Development] MariusKv:
Dont sideload

[OnePlus 8 / 8 Pro & 8T Cross Device Development] mattie_49:
You have to rename zip to pa.zip to use that command. And if you don't have A11 on both slot_a & _b this build will not work. Or at least this has been my experience.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] RoughNeck1971:
Unfortunately didn't change a thing. Exactly same error message. A11 (Beta 7) is installed on both slots.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] MariusKv:
I dident need to rename it to par.zip
[OnePlus 8 / 8 Pro & 8T Cross Device Development] spoeckes:
all the problems I had when flashing with "fastboot update" and the missing partitions were due to a not up-to-date fastboot version. just in case that happens to someone else
[OnePlus 8 / 8 Pro & 8T Cross Device Development] RoughNeck1971:
Thanks a ton man! That was it! Searched for the latest ADB / Fastboot version for windows. Found one from end of 2020. Updated fastboot and worked immediately. Never would have come to my mind. Awesome!

[OnePlus 8 / 8 Pro & 8T Cross Device Development] nijohnson:
ooops! double post - sorry
[OnePlus 8 / 8 Pro & 8T Cross Device Development] mattie_49:
It will definitely get data for us. 100 percent it's caf not aosp. Problem with us is we have A10 still on slot_a. Or at least I do. So until Verizon throws us an update /security patch and seamlessly updates our other slot. Where both are A11 . It will not work properly. I've flashed and it just continually reboots into recovery trying to factory reset. And that's after I wipe data prior to flashing In stock op8 recovery ..
[OnePlus 8 / 8 Pro & 8T Cross Device Development] nijohnson:
So to be function, the phone has to have Android 10 on slot a, and android 11 on slot b? That's weird!
[OnePlus 8 / 8 Pro & 8T Cross Device Development] nijohnson:
Bleh! More dupes!
[OnePlus 8 / 8 Pro & 8T Cross Device Development] mattie_49:
No A 11 has to be on both sides. And Verizon only has a11 currently on one slot which is _b. Because we just got a11 on Jan 27th ota. So our next security update/patch will go back over slot_a. Then will be on both sides .
