That issue has been around for a long time: https://xdaforums.com/oneplus-5t/de...os-15-1-oreo-oneplus-5t-t3730058/post76514544

Apparently it requires only one commit to be merged but haven't had any feedback. Could be an issue with the commit or maybe security concerns. I don't know :(

[MENTION=3208754]codeworkx[/MENTION] This should fix the issue if it's true. Is there a reason why it hasn't been merged? :confused: https://xdaforums.com/oneplus-5t/de...os-15-1-oreo-oneplus-5t-t3730058/post76516165

Guys as m I the only one who notices that in some graphically intense games the sound just stutters all the time?

I just downloaded Cytus 2 (temporarily free by the way..) and all the songs just stutters and it's just an awful gaming experience.

Thx

How is the battery. I have a 5t on BetaOOS but battery is really bad compared to my OP One running Lineage 15.1

I have reverted to 5.1.1 but really thinking abt lineage now.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] dlmartin:
I have found battery life is decent on the 9/3 build with 5.1.5 firmware using the stock lineage kernel with this build.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] KLit75:
I'm pretty sure I know the answer but would rather ask first.

As a recommended I'm going to try this with RedFlare kernel. Now that we've moved to 5.1.5 we need the treble version noverity zip, right?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] khan1989:
I would think so. Looking for a treble supported kernal to help fix my gcam viewfinder issues - so please let us know how it performs.:)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] OhioYJ:
What issues as you having. I've run the BkuSpark kernel, and am now testing the Franco kernel. I use the Arnova GCam port.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] khan1989:
Sometimes you get a laggy viewfinder, quite annoying as I tend to be heavily reliant on Arnova's GCam port.

Singularity currently does not support Treble based custom roms.

BluSpark doesnt support custom roms (officially).

Will try Franco now - thanks for the suggestion.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] 3lMghraby:

no

but he is on xda

the kernel has github link

this is the best kernel I have ever tried on a custom rom

OOS smoothness

It's basically a spin-off of Flash since Nate quit supporting 5/t. He allowed people to use his source as long as they changed the name. Of course it has the devs own tweaks but think of it as an enhanced Flash kernel.

I have a strange bug with the rom

When I try to change style color in settings I get a force close

I can do a workaround by wiping cache and dalvik cache

then it is fixed but if I rebooted again the problem comes back again

I am not sure why

It is working , but it stays not on , it goes black about a few seconds later....

Also there are not so many options availble , is there a way to 'up' these ? (like color, font ....)

thanks for this but you got me wrong

the commit is about the force close on using front facing camera in whatsapp and telegram xD
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Macusercom:
Well, I guess that won't do the trick then :p

The commit copies files from /vendor to /system I think. As /vendor is now a separate partition, I guess this could cause issues and conflicts. A zip should be possible but I'm not sure if simply copying the files is enough.

EDIT: /vendor has a symbolic link in /system/vendor so this commit would actually copy the file to itself if I'm not mistaken. No idea how this should fix the camera issues especially after /vendor is a separate partition now. I don't even know what causes this issue :(
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] 3lMghraby:

Hey guys,

I am currently looking to install a custom rom.

My situation right now is : OOS 5.1.5, Encrypted, Rooted and with unlocked bootloader. On the recovery side of things I have the latest Codeworkx TWRP.

I have been reading this thread but it has got me all confused. Audio problems, problems with treble support and many other things. I am not a noob per se but I am installing a custom rom for the first time in a long time(First time since FBE and treble got on the scene)

So can anyone highlight the current bugs if any? Also is there a specific procedure to flash this?

I would like to avoid formatting internal storage if possible.

Thank You

Hey guys which Firmware can be used? I've noticed there's 5.1.5, 5.1.4, OP5T_O2_Open_11_oneplus5t, and a range of others. I had been having camera lag issues and headphone jack not working. Now I'm having issues where if I use the 3.5mm jack, but unplug it I'm getting no ring tones, so can't hear the phone ring. Can I update to firmware 5.1.5 without issue? As using one of the older ones currently.

Double check if you followed the instructions of the OP. Flashing order is important. I dirty flashed the 16/01 build over the 13/01 and still have fingerprints.

I also flashed to test the nano unofficial open gapps for 8.1 (from another thread) instead of the pico and I have face unlock :good:
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] G23 Mr Gimp:
As pierrep56 states, follow the instructions in the OP and ensure you are coming from the Oreo beta. Without the Oreo firmware you'll not get far.

Anyone has a solution or an explaination for my fingerprints set up problem ?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Starbugs:
Hello everybody,

I've been using this rom since "lineage-15.1-20180105-UNOFFICIAL-dumpling.zip" and I am amazed by the stability and quality (considering the early stage) - keep up the good work and thank you :good::good:

Beside wlan not working after boot (something I can really live with), I'm having a screen colour issue. In general, the issue is independent of the built so far. Since 20180113, the issue got worse and now heavily affects the lock screen.

Setup: came from fresh, brand-new phone (screen looked good - colours where comparable to my Nexus 6P, so I don't think it is a HW issue), installed OOS Oreo Beta1, flashed twrp-3.2.1-0-universal-codeworkx-dumpling.img, installed lineage and SuperSU-v2.82-201705271822

Problem 1: lock screen has a heavy green impact (becomes especially visible when entering the PIN - the SIM-symbol is greenish and barely visible) + also when unklocking

Problem 2: screen colours don't look very good, like they need a calibration (black is more of a dark grey, white looks dirty, too much green)

what I did:

- adjusted live display settings (colour temperature was set to 8000K day, night 4800K - switched to 6500K for day), modified brightness until screen was tolerable (-60% brightness + auto setting)

- switched to FW of OOS B2 today - did not change the behaviour

Any ideas / suggestions?

Thank you :fingers-crossed:

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] 3lMghraby:
you can simply install latest build and gapps

I recommend a kernel so that you don't lose OOS like smoothness

Red Flare is the winner here https://dl.treskmod.ru/kernel/op5/

there is only two tiny bugs with this rom

1-you need to clear dalvuk on every reboot to change style color.

2-front facing camera force closes on whatsapp

other than that the rom is amazing

those two bugs if you can't live with

install latest crDroid Rom it is the same as LOS with many tweaks and the front facing camera bug is fixed.

I hope [MENTION=3208754]codeworkx[/MENTION] could add the commit to fix the issue as I use whatsapp alot and I really love this rom

Anyone knows how to solve this?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] bdwilk:
You need to create a vendor partition first. You'll need to flash either OOS 5.1.5 or any open beta after ob12 and it will create the partition.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Zark0s:
You need to flash 5.1.5 firmware and vendor image from op.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] kermex:
I want to try LineageOS, too. Could you please tell me which is the order for flashing the files in OP? I'm on OpenBeta 16 now. Thanks!
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Zark0s:
If you are on open beta 16 you already have a vendor partition, so you just have to make a backup in twrp (in case something wrong happens), save it somewhere, then format data, wipe everything then flash latest 5.1.5 fw and los from op and that's it.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] kermex:
"Format data" is the same with "Wipe Data"?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Zark0s:
Nope ! When you are in twrp, click on the wipe button, there is a " format data" button then write "yes".

I flashed the su addon. After booting (and enabling root for apps) apps can ask for root and get access. But after some minutes root goes away. Apps cant get root access. Why could this be?

-Question/problem: I'm using gcam arnova8 stable (with 5t camera library fix magisk module + pixel 2 colours magisk module) but the quality of photos, videos and audios is really bad. OOS cam is significantly better under almost any aspect. Using AOSP cam integrated on LOS the problems are more and more.. Why? Should I use another kernel? Is this a proprietary library problem?
