Rom download link leads to oneplus 9R only, is the rom "unified" ?
[OnePlus 9] chandu dyavanapelli:
Check above comment i linked OnePlus 9 download link (gdrive one)
[OnePlus 9] illusiveairforce:
Bout time we get a ROM up in this ***** bro. Woo im Excited man, playing PuBG right now. Soon as Im done. Ima flash this mug
[OnePlus 9] illusiveairforce:
Flashed it but have no mobile data....

Nevermind that, just had to reboot. All good now
[OnePlus 9] sbute:
Don't know if it's rom related but I encountered heating problems
[OnePlus 9] illusiveairforce:
I haven't had any issues. And since I'm a gamer. This ****in rom runs amazing. Every other rom seems to be less smooth or the render isn't as good while playing but this one is flawless.

Only thing I got as a minor issue would be my Google FI VPN. It doesn't work. Says not available on this device.

Any thoughts anyone? It's a Google Pixel Rom... Lol. Make that make sense
[OnePlus 9] stompysan:
Hey all. I am considering picking up a OnePlus 9 in the near future, but am needing a feature that may be implemented in this ROM. On Havoc on the OnePlus 8, in OnePlus Settings, there is an option to force a 5G mode, either NSA, SA, or both. Because of coverage at my work, I need to use this feature to force NSA 5G to get good 5G connection and not drop my calls. I am attaching an image of the option. Can someone look to see if this is available in this ROM? I would really appreciate it.

Yup 8 series all OnePlus settings available in 9 series too
[OnePlus 9] sbute:
I just did a reinstall and heat problem is gone now. For those who are using Gcam port ( last BSG's ), is video working for you ? The app crash for me and was working well on OOS 11.
[OnePlus 9] imirwp:
Thanks for your efforts. I will wait for Vanilla version.
[OnePlus 9] illusiveairforce:
Yeah I was getting up to 43 Degrees Celcius while playing PUBG Mobile, I was losing frame rate actually. So I went back to Stock. Any thoughts or suggestions?

This is this the first Rom that Im willing to ride for months.

Also is there a way to fix the model number so that my Google Fi carrier app lets me use my free VPN they give me for using there services?
[OnePlus 9] caramilk:
Adaptive charging can be enabled but does not seem to have any effect, Magisk module Advanced Charging Controller works, though.

No, I didn't find Slim Recents in the screenshots. :(

Please consider a request to add it.

It's much, much much better than the stock recents option.

Better than the old Omni Recents too, but I sure wouldn't mind having Omni Recents as well!

[OnePlus 9 Pro] Tronje:
@SKULSHADY

Thank you for your great work.

I was always using HAVOC with my previous Oneplus devices and have been happy with it.

After 2 days of using I couldn't find any issue.

The only thing is, that batterie consumption might be even a little bit higher than stock 11.2.9.9.

And: My model changed from LE2120 to LE2123
[OnePlus 9 Pro] felek73:
Does this ROM has pixel like AOD with weather and calendar events?
[OnePlus 9 Pro] chandu dyavanapelli:
Wait 3 or 5 days for rom settle to fix battery drain issue and model mismatch will fix in future builds

[OnePlus 9 Pro] oscarmaldonado:
Hello everyone, first of all, thanks Dev and team for bringing us another great rom. I'm already running HAVOC, what's recommended to update, fresh install or just side load? Thanks.
[OnePlus 9 Pro] Titaniiiic:
Thanks for this effort!

I'm asking about is this rom have throttling like the original rom (Oxygen OS Oneplus 9 pro) ? which i mean can i play PUBG on 90hz and Clash Royale on 120hz?
[OnePlus 9 Pro] Abhinav2005:
I think there will be no throttling in custom roms but you will not get 90Hz support on PUBG/BGMI as it is to be done krafton.
[OnePlus 9 Pro] Abhinav2005:
I think copy partition.zip does this step(flashing OOS in both slots).
[OnePlus 9 Pro] oscarmaldonado:
Just for everyone else I answered my own question...... dirty flash did the trick for me to update from previous version.
[OnePlus 9 Pro] JodyBreeze901:
Sorry for being a nuisance but I want to make sure that I'm doing this correctly since it's been a while. I'm guessing that the instructions for installing this software are the same typical method.

Factory Wipe

Install from TWRP and then restart
[OnePlus 9 Pro] bigdog1459:
There's a link in beginning but it uses lineage recovery not TWRP and you have to side load via adb. The link has the specific instructions you just need to swap out the os zip name to this one.
[OnePlus 9 Pro] JodyBreeze901:
Okie dokie......thanks sir. I'll double back and read the instructions a few more times
[OnePlus 9 Pro] bigdog1459:
Yeah. It's not bad just a bit different than using twrp.
[OnePlus 9 Pro] JodyBreeze901:
Yep that's not working for me....so I need to install the lineage os recovery am I correct?
[OnePlus 9 Pro] Samuel Holland:
Yes fastboot boot recovery.img then you install everything.
[OnePlus 9 Pro] bigdog1459:
So whats not working? Not trying to start stuff its just I have messed up everything you could possibly do on this device so I am trying to figure out where you are at.

I used the instructions here: https://wiki.lineageos.org/devices/lemonadep/install

Put everything in my platform tools folder and opened a powershell from there.

In a nutshell:

1. Make sure you are on latest oos (I used 11.2.9.9 when I first flashed this)

2. reboot to bootloader

3. "fastboot flash boot <recovery image>.img"

4. reboot into recovery from menu options

5. select update in recovery

6. select update from adb

7."adb sideload <copy partitions>.zip" (to make sure both slots match)

8. redo steps 2-6 (it wouldn't let me load the rom directly after the copy partitions)

9. "adb sideload <rom name>.zip"

10. then reboot system from the recovery

optional:

11. redo steps 2 to 6

12. "adb sideload app-debug.apk" to allow it to flash magisk canary (assuming you put in the same folder as your adb items and want to root)
[OnePlus 9 Pro] tjengo:
Hello.

First of all, nice ROM.

I have some problems with adaptive charging. It does not stop charging at 80% limit.

Do I need root or something else for this option to work?

Not rooted because some apps won't work.

Thanks
[OnePlus 9 Pro] chandu dyavanapelli:
Adaptive charging broken
[OnePlus 9 Pro] VoidedKN0X:
i've read about people aquiring widevine L1, i was wondering if anyone had any luck getting L1 on this rom too
[OnePlus 9 Pro] chandu dyavanapelli:
Before flashing rom flash OOS in both slots
[OnePlus 9 Pro] VoidedKN0X:
You mean like copy from a to b partition?
[OnePlus 9 Pro] zxc123ygy:
Thanks for your work. Like other lineage os-based ROMs, does havoc have the problem of frame drops when scrolling on specific app like ins twitter and facebook
[OnePlus 9 Pro] bigdog1459:
That's what I did prior to installing the rom and I have L1 listed in drminfo.
[OnePlus 9 Pro] VoidedKN0X:
i just did that too but OOS still says L3, i'm flashing the rom rn but i think it'll still be L3 as stock has L3 too
[OnePlus 9 Pro] bigdog1459:
I haven't noticed any in Twitter at least. Don't use FB as much anymore.
[OnePlus 9 Pro] bigdog1459:
Ummm. I dunno then. I don't remember what mine was on OOS. I assume L1 bit since this is working fine for me and all the shenanigans I faced to get to something stable like this, I'm not flashing back yet. Maybe due to rooting and the safety net fix stuff mines L1?
[OnePlus 9 Pro] VoidedKN0X:
i was passing safety net too and all but i still didn't have L1 so i'm a bit stuck
[OnePlus 9 Pro] bigdog1459:
Just cause my coffee hasn't kicked in yet, you did do the side load of the copy partitions from within lineage os/havoc os recovery before flashing havoc right?
[OnePlus 9 Pro] VoidedKN0X:
yes i did
[OnePlus 9 Pro] bigdog1459:
Umm. You unlocked or carrier? Mines a TMobile that I had converted to global. Just trying to figure out what's different.
[OnePlus 9 Pro] VoidedKN0X:
i have a global one, bought in belgium
[OnePlus 9 Pro] bigdog1459:
Maybe that has something to do with it then. Sorry I don't know much about the global ones. I just know about the TMobile one since I have dealt with it here. Maybe someone else who has a global can chime in?
[OnePlus 9 Pro] JodyBreeze901:
Anyone got that safety net to pass on this ROM? I've tried to get it to pass but was unsuccessful.
[OnePlus 9 Pro] PoSayDone:
Didn't have any problems with it. What have you tried?
[OnePlus 9 Pro] Abhinav2005:
Same here, not rooted
[OnePlus 9 Pro] oscarmaldonado:
Hello everyone, question, is anybody having issues with simcard switch toggle? For some reason it doesn't work for me, I actually have to go into settings-simcard and change it from there, it's not a big deal but it just makes it easier for me, other than that I really don't see anything wrong with this rom. Well done Dev. And team.

I had two quick questions;

1. Are there plans to add the OxygenOS camera to this ROM? GCam does work great but it is nice to have options.

2. Are there any future plans for an Android 12 release of this ROM?
[OnePlus 9 Pro] Abhinav2005:
1. Work on OOS Cam is going on and soon we will see OOS Cam on Custom ROMs

2. Testing of A12 havoc OS has started. Also a Custom ROM is already available which is based on A12.

hy guys

for clean installation of havoc rom op9, i have the stock oos 11.2.7.7 its correct?

thee installation explanation not is so clear, i have to flash before zip file copy-partition, then wipe, then the havoc zip? i tried but after reboot from recovery remain in loop continuoos

thanks
[OnePlus 9 Pro] this.guy.lol:
try wiping then copy partion then flash
[OnePlus 9 Pro] iaio72:
now work! thanks so much
[OnePlus 9 Pro] this.guy.lol:
np lemme know how th rom is. was thinking bout flashing but idk how well it performs or if signal sticks
[OnePlus 9 Pro] iaio72:
The rom works well, I personally find the wifi a bit slow compared to the oos, and it would be nice in the next build to have the highest vibration setting, the rest is perfect, great job to the developer.

ps the signal its very high and good.

Request: Please add Google Camera and Slim Recents
[OnePlus 9 Pro] Ravel7774:
For those who want to use microg, the high level steps are as follows:

Do the preparation steps like unlock bootloader, enable usb debugging etc so that you can execute adb

1. adb reboot bootloader

2. fastboot flash boot twrp-3.6.0_11-0-lemonadep.img

3. reboot into twrp

4. activate adb sideload in twrp

5. adb sidelock Havoc-OS....zip

This installs Havoc OS. Now TWRP does not work with OTG, how do we put microg in? Boot up Havoc OS, copy nanolx version of microg, fdroid and bromite webiew and the havoc os into the device

1. enable usb debugging, adb reboot bootloader and fastboot flash twrp onto device. This is because twrp has been overwritten.

2. Reboot into twrp

3. flash Havoc OS (maybe you can skip this step since it's already Havoc OS) from the folder you copied the files into

4. flash microg, fdroid and bromite webview from the folder you copied the files into, observe the installation messages to make sure it's installed

5. wipe, delete data

6. reboot to system

7. connect to wifi or your mobile data. (if you haven't inserted sim, wifi is needed to do google device registration)

microg, fdroid should be in your app list now

1. open microg, check all the check boxes in self check, granting permission if required.

2. do goggle device registration if you want to. reboot

3. turn on cloud messaging, reboot

4. turn on safety net reboot

5. activate location modules

Your device is ready to use with microg, fdroid and bromite webview
[OnePlus 9 Pro] chandu dyavanapelli:
Sry we don't add those features and gcam you can install manually
[OnePlus 9 Pro] break.cold:
Is possible to install rom through TWRP or Lineageos recovery?

Really wished you guys might have released Android 12 base rom.
[OnePlus 9 Pro] Ravel7774:
Yes you can use twrp
[OnePlus 9 Pro] Tronje:
After some struggeling I got Havoc installed some weeks ago.

Trying to update today in twrp gave me the message:

"Devices on super may not mount until rebooting recovery.

To flash additional zips, please reboot recovery to switch to the updated slot"

But after reboot it looks like I am on another partition (no files to flash) or I get same message again.

And in Fastboot the product name ist "lahaina"

And I can't get into edl mode (not manually and not from reboot to in TWRP)

Any idea? Thanks in advance!
[OnePlus 9 Pro] JohnTheFarm3r:
Why would they add Google Camera? I mean, it's a choice of every user since there are so many different versions. It would just make things complicated more, since most likely we would need to manually remove the cam if we don't like it and if it uses the SNAP package name.
[OnePlus 9 Pro] JohnTheFarm3r:
You can ADB sideload the ROM if you can't access your internal storage in TWRP.
[OnePlus 9 Pro] CZ Eddie:
By that terrible logic, I would ask you why they should add any modifications at all.

Why even bother to open your mouth.
[OnePlus 9 Pro] JohnTheFarm3r:
Not sure what logic are you talking about here, but GCAM or Google Camera is a SUBJECTIVE thing on most of the custom ROM supported devices since there are dozens of different developers/modders.

Not all the mods work the same and neither do they all have configuration files, so WHICH Gcam should we have in your opinion? Well, you might say BSG, and then another one will say, well I want Arnova GCAM, etc...

We can argue about this till tomorrow, and obviously, as you can see, there is a reason why the DEVs mostly refuse to implement a GCAM (they usually add some simple camera app with basic functionality), the same way this dev refused to add it. Don't compare GCAM (individual apps) with ROM functionality/settings, those are two different things.
