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.

thank u for ur help. i used the second method because the first didnt worked and now iam unbricked.

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).

do u know where u find the havoc oreo rom now ? they changed their download directory. and the overview is confusing me.

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.

hey brother. i have good news. i just want download again havoc oreo cause i deleted the old zip. i had thought maybe the oreo havoc zip was faulty. now i restored it with a restore tool. i tried again and now it works.
IAM ON HAVOC OREO . It starts but now i got a message.
"Android System

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

it's fixed in new builds, I tried latest pixel experience gsi build and it booted. Everything worked fine except camera, so I reverted back to android pie. I hope someone would find a camera fix for our device in android 10 ROM.

You need GSI Kernal from "Quantom Kernal For GSI" To Boot the GSI ROM, you can find and download it in the rom and Kernal section of the device on XDA
PS : And also Only download A-Only Arm64 version of the ROM, I have seen that latest build of ROMs work, I have only tried pixel experience and AOSP Yet.

Nope, maybe it's for the kernel

OK, i try GSI 9 and all work..... .probably problem on Quantum kernel for GSI 10 IHMO, do you find it? any suggestions?

That's what I did for getting Android 10 booted
1. Flash official ONE UI rom of android 9 ( you can go for a framework flash with ODIN or try quantum one UI rom and flash with TWRP)
2. Make A Full boot, and make sure it's booted fine
3. Go to official page of gsi roms at git hub and download any android 10 ROM with "a-only arm64" ver. ( i prefer pixel experience or aosp for yet , because I have only tried these )
PS. Don't forget to extract that ROM file to get a .img file
4. Download Quantum kernal for gsi from the " ROMS And Kernal" section of the device
6. Go to TWRP and wipe data ( Reset )
7. Flash the Quantum Kernal for gsi
8. Flash the System image of the rom that you downloaded
Then Reboot to TWRP again
9. Flash The modified Magisk provided in the download.
Credit goes to : phhusson ( i dont know rom will boot with lastest Magisk)
10. Reboot and it should boot into android 10
-You don't need any other zip file to flash

thanks!!! tonight I try, thank you very much

how to install it? and its multi language? thx

Warning! Please back up everything. You will loose data partition if something goes wrong. You have been warned. This was tested on K30 pro zoom edition with Chinese beta rom 20.7.9.
Requirements: pc with fastboot files.
Usb otg cable and USB stick at least 4gb.
Full tgz fastboot rom miui 12.0.x.x
20.7.9 and 20.7.30 recovery Chinese rom
Drawbacks with Android 11. No TWRP support. No magisk. No root.
1. Download full tgz Chinese rom miui 12. Extract it and flash stock recovery. You can skip this step if you have stock recovery already.
2. Fastboot boot into TWRP recovery using fastboot.exe. Do not flash or replace stock recovery. Phone will restart into TWRP.
3. Download 20.7.9 and extract file META-INF/com/google/android/update-binary and replace inside 20.7.30 rom.
4. I used USB otg cable with USB stick to flash in TWRP the patched rom.
5. Wait little as first boot is long.
Edit: this should be obvious, it is a Chinese rom so only English is supported.

Android 11 (LineageOS 18.1) & TWRP

I installed LineageOS 18.1 (Android 11) on my OP7P and want to boot (or flash) TWRP.
There is a lot of different information about the state of TWRP on Android 11.
I hope someone could clearify the following questions:
1. Does TWRP [3.5.2] support Android 11?
the release notes of 3.5.1 state that they "prepared a mini release before Android-11 support."
The release notes of 3.5.2 don't mention android 11 at all.
There are various people in the LOS18.1 thread that can boot twrp, so I assume there is some kind of (partial) support.
2. What if 'fastboot boot twrp.img' doesn't work?
For me I can't boot (or flash) TWRP (on LOS18.1).
So as the twrp/lineage os guide says I do:
fastboot boot twrp.img
Click to expand...
Click to collapse
It finished succesfull, but my phone stays in fastboot and doesn't reboot.
The TWRP guide says the following:
If fastboot boot command doesn't work you need to root your device and flash the TWRP installer (remember that flashing the TWRP installer you will lose the root).
Click to expand...
Click to collapse
I find this a very vague description; what do they mean with "doesn't work"?
(when I flash twrp it results in an unbootable phone, might be related to a/b partitions, but I have not enough knowledge of that)
3. Does TWRP work on encrypted phones?
I found various posts that suggest that TWRP doesn't work on encrypted phones.
I can't find any reliable source that supports that statement.
Twrp says this, but that doesn't clearify things at all.
I hope someone could give me some answers, or guide me to some reliable source so I can find it myself.
I find the documentation of LineageOS and TWRP lacking in that perspective.

For question 1, there's no official TWRP for 11.... YET.
Question 2 - I'm thinking cause TWRP doesn't work for 11, that's your issue.
Besides that, if your trying Android 10(because you don't mention what version your using in question 2), I would suggest re downloading, as that process works fine for this phone I'm typing this reply to you on.
Question 3 - I'm sorry, I've got ideas, but it's above my pay grade... So no hard knowledge I'm comfortable calling advice, to give a fellow OP7P owner.

I also think there is no official TWRP for android 11, but twrp doesn't make this very clear in their docs.
Multiple people are claiming they are able to (at least) boot twrp on Android 11.
LineageOS 18.1 is Android 11 (but I will clearify the post).
Thank you for your reply

there is now a working TWRP version for Android 11.
Nebrassy version: https://forum.xda-developers.com/t/recovery-11-unofficial-teamwin-recovery-project.4289455/

This works for me
Fastboot boot into TWRP,, ( TWRP nebrassy edition)
install trwp via advance settings
reboot into recovery
send a copy of your ota oos over to your phone ,
flash oss ,
reboot into oss recovery
Format data in oss stock recovery
Reboot

just find a way to relock your bootloader, it will revert you to stock completely.
