That turned out to be my fault. After flashing Havoc I forgot to reboot into TWRP so I tried flashing again and then rebooting and it all worked as expected.

I do have another problem however in that now that I am running Havoc I find that I can not turn cellular data off. If I do turn it off it turns back on after a few seconds. Any suggestions on this one? :confused:

dirty flash is not recommended, do not do this at home !! ))

knowing how oneplus6 is unstable, I guess it's a pure miracle that my phone is still working.

just for quick relieve,

go to fastboot, backup your data, flash twrp, boot twrp, format data, flash oos on A/B, flash this rom, done.

also, you must follow first page instructions in exact manner.

[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] hyddro:
How do I install OOS in both slots.. I had OOS running before I attempted to install anything.

Basically did this:

- wipe system, cache, data

- install havoc

- install twrp zip

- restart to twrp (get warning about no OS installed)

- phone goes into black screen of death...

I tried this x3 with OOS beta and 9.0.4 stable and no luck

[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] BarrySamuels:
I could really do with some help here as my system is only partly usable. :crying:

I was running OOS Oreo and updated to OOS Pie on both slots then installed Havoc on both slots.

The biggest problem is that mobile data is shown as on and if I turn it off it turns back on a few seconds later. Mobile data is also showing as on even when wifi is on (wifi works) which I thought wasn't right.

I'm not sure how Quick Settings is accessed in Havoc but I can swipe down from the Status Bar and I get one row of icons. If I try to swipe down again I don't get any more. Should it work that way?

I have re-flashed Havoc on both slots but it has not made any difference.

I would really appreciate some help from the clever people out there. :o

When I try to switch from a different ROM, the only problem I ever face is when I reboot to TWRP to flash OOS for the second time my storage is encrypted and TWRP can't decrypt it.

I wonder how people "make sure they have OOS installed on both slots" before flashing the ROM. I've done so much searching over this and not able to find a way to flash OOS a second time. I don't want to format my entire storage. Anyone knows how to get it done correctly?

How do I "make sure I have OOS installed on both slots" before flashing Havoc and without getting my storage encrypted.

[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] jacdelad:
I had the same problem. I remember installing OOS in bother slots, then TWRP, then reboot to TWRP and reformat data. use MTP in TWRP to copy rom to internal memory or use USB. This should do it.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] shaunakdsilva:
I'll need a stepwise order of how to do it. Coz I've this what you just said and ultimately... When you do reboot to TWRP to flash the ROM you can't flash the ROM anymore coz your devoce is encrypted.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] cmart4:
likely because this is on march security and oos is not.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] shaunakdsilva:
Doesn't make sense because I'm talking about the steps before flashing havoc. I haven't even touched havoc rom zip in what we are talking about.

from [MENTION=4294264]dolorem[/MENTION]

Ok, did the following procedure:

Wiped System, Data and Dalvik / ART Cache (TWRP SHOWS CURRENT SLOT = A)

Flashed OOS (from Oneplus downloads) and TWRP (OOS FLASH 1/2 DONE)

Booted back to TWRP (TWRP SHOWS CURRENT SLOT = B)

Wiped System, Data and Dalvik / ART Cache

Flashed OOS (from Oneplus downloads) and (OOS FLASH 2/2 DONE)

Booted back to TWRP (TWRP SHOWS CURRENT SLOT = A)

Started following OP's instructions from this point forwards

Did a system wipe (Data, cache, Dalvik)

Flashed HavocOS 20181022-oneplus6-Official and TWRP zip

Booted back to TWRP (TWRP SHOWS CURRENT SLOT = B

Now TWRP shows that /sdcard contents are garbage, and adb push says "Required key not available"

Edit: solved with the following:

Formatted (not wiped) Data

Flashed OpenGapps and Magisk

After this the phone booted normally. The crucial step compared to any of my previous tries was formatting, not just wiping data.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] shaunakdsilva:
I really appreciate this but this didn't work. When I reboot to TWRP after flashing OOS and TWRP the first time I am unable to flash OOS again because my /sdcard has already started to show garbage. Geddit?

How do i flash it again when i can't locate the oos file?

---------- Post added at 10:46 PM ---------- Previous post was at 10:35 PM ----------

Let me describe the problem again.

Let us say I am currently on ROM xyz on slot A. I want to switch to Havoc. So I follow with getting my prerequisites in place which is to have OOS on both slots.

1. Boot to twrp and flash OOS and then flash TWRP without rebooting. Done

2. Reboot to TWRP because I need to flash OOS again.

After rebooting to TWRP, my storage is encrypted hence I cannot flash OOS again.

Let us assume I "format" data and not wipe it. This results in formating my entire internal storage hence i lose all my flash files. How do I flash OOS again?

Can't complete steo 2 because of encrypted storage.

How do people manage to do this without losing files from internal storage?

Note: If we gonna wipe system partition after flashing OOS what is the benefit of even flashing OOS in the first place?

Nothing makes sense.

[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] parkbank:
First of all I'd like to say a big thank you the HAVOC OS team :) You did a really great job!

I have a question regarding the secure boot feature. My usual phone setup is to encrypt it with a strong passphrase that is required before booting and to use a weaker and therefore much more convenient PIN for unlocking the screen. After having entered a wrong PIN, my phone reboots automatically and then requires to enter the strong passphrase in order to boot.

My OnePlus 6 with HAVOC OS installed, doesn't offer this option. It is encrypted, but it boots without any password prompt and only for unlocking my screen I'm required to enter my weak PIN. However, the /data partition is encrypted as far as I understand.

Because I really like the idea of a strong passphrase that is required for booting my phone, I'd like to enable this feature. Is there any way to do so? Is the secure boot feature part of the ROM? Is it unavailable in general for Android > 8.1?

and it was ok for me until I noticed the different in comparison on closer look.

I tried different screen modes but the result is the same.

Enjoying the rom a ton so far. A couple hiccups though:

Edge gesture's height setting isn't saving.

Fullscreen games aren't resizing to avoid the notch (leads to missing game elements)

Nav bar coloring is pretty wonky (Probably upstream and I think most of these solutions have similar issues)

Right now I'm hunting for a gesture replacement and a fix for the notch issue, as those are quite annoying, but I'm definitely looking forward to testing more updates.

Flashed just like you always flash any ROM. No issues.

My only "complaint" would be the camera, that I personally just can't get into.

It's noticeable worse compared to 5.1.9 - especially when using Snapchat, Instagram, FB etc.

Also, there's no 19:9 ratio in the original cam, which would be nice.

This is Android 9. I'd recommend you do some reading about flashing ROMs on slots A/B. The error you are getting is because you are flashing the Gapps on the wrong slot and you haven't followed the instructions.
