Thats why i need vowifi
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] AdamWill:
It's effectively a preview of the next official release; it's built by the same dev who does the official builds for our phones (thanks, codeworkx). When LOS 16 itself is official, and this build is in good enough shape, it'll likely be made the official build, taking over from codeworkx's 15.1 build.

How do I apply the bokeh effect on the camera??

Just checked the ROM and volte doesn't work. Turkey Vodafone. In menu of 4636 ims is registered but WiFi calling and volte is unavailable under ims info tab.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] ymedesines:
Mobile data for sim two should not default to on for snapdragon 835 chipsets; it tries to make volte calls out sim two and crashes telephony.

OP5 and OP5T need mobile data disabled on sim 2; as do all odler OP phones; OP6 and 6t can handle dual volte with the 845; the gapps setup flow just sets preference for internet gateway, it doesn't disable data so when calling out sim 2 it tries to make volte calls. It's inherent from aosp that it does this, but it's because the aosp code doesn't account for dual sims correctly.

Update your TWRP or open the zip and delete compatibility. Zip from inside the update zip file
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] yubyub:
Once in a while, usually while in FireFox, the system locks (goes back to the lock screen) and I get "No SIM" for a moment, then everything starts working again.

Does anyone else see this? My setup is a very clean install (straight from the latest Oxygen OS, full wipe, flashed Lineage, that's it - no data held over or such).
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] rooban90:
Experienced this SIM issue in older builds. But I am not experiencing it anymore in the latest build (using it for 2 days)

I can replicate this with Room 3 (game) except I get a soft reboot. I'll try to get a log tonight from adb since the soft reboot prevents an app from being useful

How to know change log or what feature has ROM?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] angelus errare:
In Android 9, the default behavior for the volume control was changed to always control the media volume. Does lineage plan to change this back to the ringer or leave it as is?

If it's staying, does anyone know a way to change it back?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] 3lMghraby:
system/buttons/control playback

that feature is in custom roms for ages aosp is behind in that department ;)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] yubyub:
Doesn't appear to restore the volume controls to the ringer, at least not from what I can figure out. But thanks - you got me excited that I could have that feature back ;)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] 3lMghraby:
yes my bad but it was on lineage 15.1

you can use the alert slider to compensate for it being missing
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] fbousk:
Hello here is the log for my auto rotation bug,landscape when on portrait sensor seems sick.

Could you please look at this thanks for your work?

This happen only on all customs roms,not on OOS or GSI treble rom,very strange.

Problem since pie firmware or vendor..

.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] yubyub:
Thank you for gathering the logs - I've had the same issue on many custom ROMs, but only on pie. Oreo seems fine. Hoping we can find a root cause here...
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] C.Flat:
The 1/27 build seems to be very aggressive with auto brightness. Keeps resetting itself
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] dlmartin:
I have noticed a similar behavior with auto brightness. It is working, but starts out brighter. I have been on Lineage 16.0 for a couple of weeks coming over from 15.1. So far 16.0 is solid on my 5t. I am on blu_spark 9.91, 9.0.3 firmware, and the 1/27 build. I used the migration zip for official to unofficial a couple weeks ago with no problems. Battery life was not bad on Oreo, but on Pie it has improved. My GPS lock time on Pie is much faster. Everything just works on this rom! Thanks Codeworkx and team good work!
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Troldefader69:
I am currently on Official LOS 15.1 and newest codework TWRP, can i just flash the newest update(Android Pie) directly from my recovery? Another question, what do i use the migration .zip files for?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] dlmartin:
You can go to page 20 in the thread and you will find the order to go from 15.1 to 16.0. You would use the migration zip (official to unofficial) if you don't want to do a clean install and loose your data. It worked well for me. Follow the guide, you will need to flash at least the 9.0.0 pie firmware in twrp before the rom.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] xerrr1024:
Yes, it does.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] juanval1:
Hey, are the migrations tools necessary if i want to switch from OOS pie beta? And do i need to flash OOS 5.1 if i'm already on OOS beta 24? Thanks
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Zark0s:
Hi ! The migration zip is necessary when you switch between lineage official/unofficial. So in your case, it's useless.

And no, you don't have to flash OOS 5.1 because your phone supports already treble. Just follow the steps in the 1st post and flash latest firmware (in the downloads section) to avoid possible issues.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] codeworkx:
new build up. comes with new livedisplay implementation.

also uploaded new addonsu zips.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] juanval1:
Thanks! To flash the firmware do i need to wipe system and data?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Zark0s:
Wiping system and formating data is required when you install a new rom. It's not needed when you flash an update or firmware.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Cueball666uk:
Gonna take the plunge later this evening, just wanted to check 2 things first ... Could anyone tell me if hotspot works and also if I flash magisk can I use android pay properly ! Thanks for any answers in advance [emoji846]

Messaging app

Hello again, and thanks for the new builds! I've noticed a few odd things around the Messaging (SMS) app in few late builds:

Whenever something's happening I get notifications about "Messaging is running"... this appears and disappears very quickly but several times when using the app. I couldn't find a way to disable it. Is this some setting in the rom or the app?

When I get a new SMS, there seem to be some quick reply options in the pull down notification, "Yes", "no", "hehe", etc. Is there a way to disable or at least customize?

Most importantly, the app doesn't seem to be doing "new SMS" sounds. :(
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] HipHopBlond:
Thanks for your hard work, I could say this was the most problematic migration for me ever (coming from 15.1). Pixel launcher issues, magisk issues, spoofing, titanium backup issues, data restoring issues, gpay issues... etc. I just hope it's easier migrating from unofficial to official build later on, as you say.

Upgrading ADB, TWRP, Firmware, and Installing ROM+GAPPS and Rooting was the easy part.

Either way, rom is working great and it's super smooth.

Took me a day, but I was able to setup everything. Thanks for your hard work, I'm happy google and lineage os are working on restoring app, data, info easier. Subbed!

I installed the custom rom, but i noticed the dash charge symbol does not appear, does it support dash charge?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Cueball666uk:

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] farscaper11:
I have a cell repeater in my house, noticed that my mobile is not receiving a full bar. With the original OOS it did. Any ideas?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] M3drvr:
It definitely charges just as fast, so I think it's just a cosmetic thing that's not showing.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] rooban90:
Latest build has no SIM disable issues.

with minor changes got safetynet working without magisk

Google pay/intune/Teams/IRCTC works fine. :svetius:
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] C.Flat:
I was able get Google Pay to not see my phone as rooted after I installed these 2 modules and adjust the build fingerprint in terminal emulator by running "props" and going through the menu.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] HipHopBlond:
Google Pay

Same here, but I have the official payed busybox. Little that I knew, Gpay is not supported in my country. I'm not getting a VPN for this, it will get way too janky.

I hope one day we won't need to root and install custom roms to our phones to get everything we need like recovery, app restore, in-depth tech monitoring, pixel launcher with the gnews feed, adaway, etc... that's the only thing stopping me from sticking with Oxygen, my phone is the last thing that I keep hacked.

I don't think this day is coming soon though. :rolleyes:

Dash charge is working, I think, also my battery hang on way better than with Lineage OS 15.1.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Cueball666uk:
Just out of interest has anyone actually been able to make a payment using gpay after installing magisk [emoji23][emoji1787] I've heard stories where it says it should work and then will not actually process payment at the till on other people's phones ? Thanks
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Cueball666uk:
Could i ask what "minor" changes you made to get google pay working without Magisk thanks as i would like to do the same... Thanks :)

hi everyone,

I use this rom since one month, its work very well so really thanks you.

But i have two minors bug, i would like if i'm alone with there.

1 - when i set/unset plane mode, my phone don't ask me PIN code, si i need to reboot. This is a bug or maybe something to change in parameters ?

2 - i cant use video record mode with camera, it make a force close directly.

Thanks for your answer, i alway search in this tread but i dont find response.

PS : Sorry for my english, it's not my main language.

Bye :)

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] codeworkx:
Does radio work after disabling airplane mode?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Cueball666uk:
WiFi is still working, just sim isn't re-initialising after toggling aeroplane mode. Then requires a reboot to get it to ask for the sim pin again.. Sorry for delay have been away on business.

Did you successfully flashed gapps ? When I flash them it boots to recovery :/
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] AhmedFaiz:

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] AhmedFaiz:
I just flashed suaddon zip and SuperSU zip after that still can't get the root!

Can some plz explain me the steps for a clean flash to get root working? When to flash the SU add-on zip do I need to flash anything else after that?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Jean3939:
I will try gapps nano maybe it's a problem with stock gapps

edit : it boots with nano gapps, it's so sad because I prefer stock gapps
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] AhmedFaiz:
Have you got root yet! What was flashing steps you did.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] mad4some:
I would assume that you just flash the add on by itself, but am not sure. Maybe [MENTION=3208754]codeworkx[/MENTION] can chime in on root requirements for official build. ;)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Jean3939:
I booted into recovery to flash magisk but I'm unable to decrypt storage ! I'm running official TWRP
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] AhmedFaiz:
So you got magisk working?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Jean3939:
No I wanted to flash magisk after booting, but now when I go into twrp I cannot decrypt data even with the good password
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] AhmedFaiz:
If anyone got root on the latest build plz share the procedure. Won't like to get the root work.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Jean3939:
also I can't pass safety net. even without root
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Seferi:
You have to flash the migration zip from first post if you are coming from unofficial build.

1. Reboot to recovery

2. Flash migration zip (unofficial to official)

3. Flash official Lineage 16 zip

4. If you had magisk on unofficial build already then you don't have to flash again. It should flash automatically.

5. Reboot

These are the steps I have taken and everything works, including root (magisk).
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Jean3939:
Sadly I completely formatted, I came from OOS. Why I can't decrypt my data with the official twrp ?

Edit : I switched to codeworkx twrp and I now can decrypt data and install magisk. I still have a bootloop with stock gapps though.

re-edit : magisk breaks data/lte
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] maeries:
How is the image quality of the camera compared to stock rom? I heard it's the same since the camera driver is open source. Is that true?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Seferi:
No idea. I'm using gcam which has an amazing quality. Here is the link: https://xdaforums.com/oneplus-5/themes/google-camera-hdr-t3655215/page485
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] maeries:
That's awesome. Does it work with microg or do I need gapps?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Seferi:
It should work with microg as well.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] trancinguy:
Is this the correct way from official Oreo with Open Nano Gaap and Magisk, pie recovery - wipe only system - pie firmware - official Pie ROM, Pie Gaap , and for SU is Magisk OK or do we have to use the add on SU 16, and do we have to boot once before the SU or unnecessary, thanks.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] M3drvr:
And? No one can without magisk if you have unlocked bootloader and unmodified kernel.

ThankyouandHelp!

Thanks for your development!

Currently running latest and final Lineage 15...

Trying to update to 16.

In TWRP I'm getting an error code- problem with Treble and a few other things.

I did try a factory reset.

Not sure what I'm doing wrong?

I figure it has something to do with firmware?

Tried flashing Android 9 from One Plus first, same error codes...

Tried flashing the firmware you have posted, same problem...

Also mat be my version of TWRP- what I was running with Lineage 15. Do I have to change the TWRP image for 16?

Thanks.

Nope

Ok, now...

Guy's- S

Something wacky.

Wiped (formatted) everything to start fresh.

Made back ups.

But can seem to transfer anything back to device from Win10 pc so I can flash new ROM or backups...

Nothing in TWRP to flash, but Internal Storage in TWRP reads 53878mb so, something is there.

Can't find anything to flash internally though, and again, can't seem to transfer files. OP5t registers in file manager on Win10 pc and shows device internal storage but is empty.

Help!

Thanks
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Seferi:
Format internal storage through TWRP and reboot to TWRP once and then connect the device to PC. It should work.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] HipHopBlond:
I can not believe it, it actually went down perfect... no errors whatsoever, thanks! I guess keeping everything up to date does pay off. Codeworkx has done a brilliant job so far! This was way less painful than my original migration from 15.1 to 16, I even passed google play certification without re-spoofing the device.

:highfive:
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] secutor666:
Okay. Sorry in advance because I feel so dumb. I don't do this often enough. I'm just as confused about the order of flashes necessary to make it work as some other people here. Might need a little jump start before I brick my 5T.

So here is the thing. I was a bit lazy and I am currently running OxygenOS 5.1.1 heavily modified with Magisk and TWRP 3.2.1 by blu_spark v8.73 without treble and not encrypted.

1. I'm a bit lost about TWRP. So do I need a Pie-compatible TWRP version to flash Lineageos 16 or do I need to flash the Pie-compatible TWRP afterwards? I've tried twrp-3.2.3 from codeworkx and the tremble version from blu_spark. But I couldn't enter the recovery anymore and flashed back to 3.2.1 with Flashify and everything is back to normal.

2. So in case I can figure this TWRP-situation out: First I have to flash the new 9.0.3 firmware, then the ROM, Gapps (nano) and reboot into the system. And in theory (cuz I've read that some ppl might have issues with this) I can go back to the recovery and flash Magisk?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] ganeshbiyer:
The magisk gets installed but the manager for some reason is missing. Just install magisk manager again. Probably just get it from Magisk zip.

CTS fails though. Had to use magisk props module.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] dsahai:
So after multiple attempts, I finally got my 5T running LineagOS 16. However, whenever I apply an update, or download and install a Magisk Module, and restart my device, it goes into a bootloop (stuck on "Phone is starting..."). The only way I figured a way around is to load the Magisk patched boot image in TWRP each time before the phone restarts.

Does anyone have the same issue? Is there a fix? I didn't have this issue with 15.1 and Magisk.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] zuixian:
Beautiful ROM :D

* Oneplus 5T 128GB

* Came form OOS9.0.4, Magisk and TWRP (3.2.3-0-20181227-codeworkx-nocompatcheck-dumpling.img)

* LOS to internal storage, Factory Reset (no wipe), flash LOS, OpenGapp and Magisk.

* All went well (except had to re-flash Magisk again for some reason to get Root)

* Titanium restored most apps.

* Now on MGC_6.1.021_BSG_Arnova_TlnNeun_V1.3.030119.0645.apk (Good app:good:)

* Just updated to 20190303 build (flash in TWRP, not necessary to re-flush Gapp and Magisk)

(Hope the above can be useful to someone.)

One happy LOS16 user :laugh:

---------- Post added at 01:53 PM ---------- Previous post was at 01:45 PM ----------

Had the "Phone is starting...." screen multiple times, rebooted again and all OK after 2nd boot.

Hope this helps.

P.S. now on 20190303 build and issue persists
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] dsahai:
Yep, issue persists for me too. Running the latest nightly build, and I have to flash the patched boot image every time. I tried restarting multiple times, but the issue never really went away for me sadly.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Zark0s:
AFAIK it's a Magisk issue... If you need root, flash the su addon in the downloads section.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] dsahai:
Thanks, at least that's good to know. I tried getting the SU add-on but couldn't find a link for SU for Lineage 16.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Zark0s:
There is a link in the 1st post in the downloads section ;)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] InsaneNutter:
For anyone having trouble flashing, I never realised that a newer recovery was required to install Pie roms, after flashing the firmware. The TWRP site lists twrp-3.2.3-1-dumpling.img from 14/08/2018 as the latest build.

Using the twrp-3.2.3-1-dumpling.img recovery I flashed the firmware_9.0.3_oneplus5t.zip firmware.

I then flashed the twrp-3.2.3-0-20181227-codeworkx-nocompatcheck-dumpling.img recovery from fastboot.

After that I could flash LineageOS 16.0 without issue, followed by Open GApps.

I'm very impressed with LineageOS 16.0, it was certainly worth waiting for. Thank you codeworkx and all involved.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Prometheus:
Is the official nightly encrypted? Is there a way to known if a rom is FBE or not?
