Question About the Beta P Program on Verizon

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.

is there a way to install magisk manager (beta) and being able to patch the boot.img without passing through twrp?

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.

should i try to flash again the factory image?
or maybe opt out from androind p beta, install back oreo, root and flash android p without deleting my data?

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.

[Newbie Question]TWRP gone after OTA update OSS 5.1.6

I have an oneplus 6 with official OSS 5.1.5 and TWRP installed. But after OTA update my phone to OSS 5.1.6, i cannot boot to TWRP anymore. Is TWRP gone after OTA update? My OEM unlocking still unlocked.

Have u not read anything in these forums, tutorials or anything?
There are like 50 threads on how to upgrade and about the new partitions for op6, it is even clear when u installed twrp too

Hi, just to clarify when you install an OTA on the oneplus 6 it uses the new partitioning system which is different so to remedy the situation just try reflashing TWRP enchilada installer using fastboot.

Previously, i've installed Beta(unofficial) version of TWRP, now i want to re-install TWRP with Official version , do i need to remove or do something firstly?

To fix it just download the official TWRP for oneplus 6 from the official team win recovery project page and then you put that on your phone, and flash using your currently installed TWRP then after that make sure you also install the root package as installing the new version of TWRP will modify the new boot image, Also a good time to mention that it will install in both slots (Seamless update slots) Treble slots if you will just to be aware.

Just follow one of the many upgrade guides. Skip the part about upgrading to 5.1.6 but for the rest follow the steps exactly. No need to explain all this in yet another thread imo. You'll need a pc though.

that's would be great if twrp can be flashed and stays there without wiping as well as root.

You can't boot into twrp because it's not there anymore. The OTA created a completely stock version of the OS that you're now booted on. You need to reinstall twrp and magisk according to the posted guides. This is going to be the case with all OTAs. The stock updater looks for root, and when it's there, it installs a complete OS, not an incremental update.

Which version of TWRP bluespark?

I just currently got the latest ota and let it install and I installed magisk from the manager by choosing to install to inactive partition after ota. That worked flawlessly and was able to keep root. But I lost TWRP of course. I was using the official TWRP. I've been noticing everyone going to TWRP bluespark recovery. But which one do I download??? From what I understand there is a version for oos android 8 Oreo and a version for oos android 9 pie. I'm on official oos pie. So which one do I need?

Just take the latest official TWRP and you are fine. Trust me.

Thank you. But still would like to know if I decide to use bluespark version.

Sure. If you want to use Blu Spark TWRP use this one twrp-3.2.3-x_blu_spark_v9.86_op6
IMG and zip files are here https://forum.xda-developers.com/devdb/project/?id=27466#downloads
You can use TWRP official or Blu Spark TWRP. What ever you like. Blu Spark is recommended for people coming from oos beta to stable

May I ask what the difference is?

Just to add a note to you for next ota.
After ota is installed go to magisk manager
Press download
Search for twrp a/b
Install (don't reboot)
Now go to main screen and press install
Choose to inactive slot (after ota)
This way you keep both twrp and root
Happy flashing

Havoc Pie downgrade to Havoc Oreo doesnt work

Hey guys. Iam trying 1 week to get Havoc Oreo.
I used this https://forums.oneplus.com/threads/oxygenos-9-0-ota-for-the-oneplus-6.909533/ to get base Oreo Rom on my OP6. This works.
But when i want to flash Havoc Oreo (Havoc-OS-20180904-enchilada-Official.zip) via TWRP (twrp-installer-enchilada-3.2.2-0.zip only this Version works for me) i get a loop in fastboot.
Can someone help me pls?
My instruction:
1. Flash downgrade
2. Go fastboot, boot TWRP
3. Flash TWRP via ADB SIDELOAD
4. Restart to recovery
5. Flash Havoc Oreo via ADB SIDELOAD
6. Restart
7. Bootloop Fastboot mode
thanks for any help.

OK, so I am not sure what exists in the OnePlus forums but lets start with:
1. You are aware there are two sets of partitions on this device correct? If not, please read here: https://forum.xda-developers.com/oneplus-6/how-to/guide-noobs-guide-to-b-partitions-op6-t3816123
2. What are you running now?
3. You need to update your TWRP to blu_spark but I am not sure if the latest (v9.91) works with Oreo... I know that v9.86 works with Oreo for sure. Read and download from here: https://forum.xda-developers.com/oneplus-6/development/kernel-t3800965
4. Get the appropriate OOS zip file from this thread: https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-mirrors-official-oxygen-os-t3792244
Specifically OOS 5.1.11: https://www.androidfilehost.com/?fid=1322778262903980680
The basic steps should be like this (all assumes you have and unlocked bootloader):
1. If you are running OOS 5.1.11, reboot to fastboot
2. Boot blu_spark TWRP.img - fastboot boot twrp.xxx.img
3. Flash OOS 5.1.11
4. Flash blu_spark TWRP.zip to get it on both slots
5. Reboot to RECOVERY
6. Flash OOS 5.1.11
7. Flash blu_spark TWRP.zip
8. Factory reset in TWRP
9. Flash Havoc Oreo zip
10. Flash blu_spark TWRP.zip
11. Reboot to RECOVERY
12. Flash GApps
13. Flash Magisk (optional if you want root)
14. Flash no-verity if you plan to run unencrypted. (optional)
My advice is to READ READ READ before going forward with anything. The A/B partition layout is far from the traditional days of a single partition layout with a recovery partition. Educate yourself or risk bricking your device and opening up a whole different set of problems.

i do this by step by step but now iam bricked. after all it want restart but it glows only the blue led

It does sound like you READ READ READ before proceeding... My steps were not intended as a step-by-step guide, which is why I said the steps "should look like this". You didn't answer any of my questions, so I have no idea where you started from or where things went wrong to get you into this state...
Can you get into fastboot mode?
If so, try this thread first: https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665
The fastboot restore method will ONLY work if you know which OOS you were running before you got bricked...
If you can't restore from fastboot images, try this thread: https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892
I cannot stress enough, you MUST read all the steps and understand what you are doing before doing anything. If you have any questions, ASK before proceeding... Good luck.

You are back up and running, good work! Congrats!
When you say the device is 'locked', you mean the bootloader is locked again? It shows 'Locked' in fastboot? Obviously you need to unlock the bootloader again before proceeding if this is the case...
And 'Yes', it is normal for 'bootloader version' and 'baseband' to be blank. It shows the same on my device anyway, and I can flash custom ROMs with no issues, and everything works.
At this point, you should be able to follow the steps in my post, making sure you first unlock the bootloader (which will wipe all of your data). You might want to format data (not just wipe as well) to start fresh. I would also confirm that there are no issues running Havoc Oreo with encryption (I'd recommend asking the question in the Havoc OnePlus telegram channel, https://t.me/havoconeplus). After people ask to "Why are you running Oreo?!?!", you just might get an answer... I dumped being encrypted after about a week of having this device because it made moving between ROMs more difficult.
In step 14, I mention the no-verity file to remove force encryption. I have attached it to this post. Again, you may want to have /data encrypted (necessity, personal preference etc.) so this isn't mandatory but I found it made flashing different ROM's much easier (personal preference really).

Looks like they removed Oreo builds, you might be out of luck. Check out XenonHD 8.1 thread if your set on running Oreo, was updated to Dec. Security patch.

Did you flash OOS 5.1.11 on both slots? I know you said you were on OOS 5.1.5 when you did the MSM tool restore.
Unsure if the Havoc build you are running requires a certain FW. Usually the devs update the blobs on customer ROMs based on the latest releases of OOS. In this case, 5.1.11 was the last version of OOS Oreo.

i was on 5.1.5 and flashed 5.1.11 on both slots and then i flashed havoc rom

I'd recommend just going to Pie. I haven't run Havoc in over a month but the latest AEX is solid and battery life is excellent. The Pie ROMs have stabilized significantly in the last month.

i just flashed the latest havoc rom now. Really really thanks brother. ur a good boy.
have a good year

is it possible to upgrade from pie hos to a10 oos using local update?

hello there.
sorry for making a new thread .. ive asked my question multiple times no one answered properly. so here's the situation:
just received the phone from china . i'm on android pie hos. and want to update to ob7 . having root and twrp is it the right way to do it? :
1. update to ob7 using local update and full zip file.
2. unlock the bootloader and flash twrp 70 (or 74 i'm not sure?) using adb
3. flash magisk and twrp installer in twrp recovery
4. done!
i heared its better to use twrp 70 and dont know the reason. whats wrong with the latest version?

Not sure if that will work, but locally upgrading from h2OS to OOS worked on my old op6 when I had it.
If it does not work;
Backup your files first then you need to unlock your bootloader.
Then boot twrp via command prompt. Once booted into twrp. Wipe data and do a factory reset there. Flash twrp installer then reboot into recovery.
Flash OB7, twrp installer and magisk then reboot to recovery again and flash ob7, twrp installer and magisk then reboot to system
I'm using .74
Not sure what the problem is/are.
Regards

Which route you want to follow twrp or official? If its official i'd say try the msm tool.. That will put you on oldest pie and then you can do OTA..
Twrp is self explanatory..
