Can anyone please tell me how I can return completely to stock? I flashed this using the directions on the wiki, including the part about copying the a/b slot, but wasn't able to get the phone to boot if I also installed Gapps, so I'm just on vanilla LOS right now and I'm not enjoying it. I want to just go all the way back to stock, or as close to it is possible, but all the guides and downloads I can find seem to be severely outdated. Like MSM Tool, for example, which I can't download anyway because the links on their site aren't working.

I promise, I've searched everywhere before asking, including this thread, the MSM Tool thread, and several others both here on XDA and elsewhere (it seems like when I've seen other people ask this, the response is always to the effect of "search this thread, it's been posted before"), but I just can't find, or am not recognizing the solution. Please help.

A short question ....

I still have the OxygenOs11 installed without a volte and I want to switch to LineageOs.

Is volte implemented in LineageOs18.1 or do I have to do it myself...like in OxygenOs....?

Following up on my Tmobile to International conversion + vendor firmware update. I did the vendor firmware update and it worked like a charm. I now have a Sept 2021 vendor patch date. My LOS installation was not clobbered at all. Is there a definitive indicator that I'm successfully converted away from tmobile's firmware other than build names?

Everything seems to be working just as it was. There is one thing that worries me though: The VoLTE option is shaded out and disabled. This was the case even before I did this firmware update. I could swear I had VoLTE setting enabled before, but it may have changed when I installed the September 24th LOS build from an earlier August build.

About firmware update. I opened FASTBOOTD mode in recovery then opened cmd in pc. tried the first commad "fastboot flash --slot=all abl abl.img". pc says "waiting for any device". Device manager sees the phone as "ONEPLUS A6013" with an exclamation mark. What am I doing wrong? ı don't know how to fix this.

Hi, while the oversaturated colours have been fixed with latest build on fajita (srgb is persistent), it seems that srgb is still to saturated on enchilada. Actually, I don't see a big difference between standard and srgb, when it was more visible before the A11 fw upgrade.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] psychopac:
Sorry for going a bit off-topic but I installed OOS11.1 (the latest update) and straight up, the colors looked dull. What I realized a week or two later is that they looked dull on lower brightness, we're talking ~15-20% brightness. I increased it a bit more and the colors began looking much better while using Display P3 calibration with the tone slider at middle.

I know it sounds stupid but have you tried changing the brightness level?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] hayvan96:

I'm sorry, but I need more help than that. This img is OOS 10.3.9 (which is Android 10) and the LOS I have installed is 18.1 (which is Android 11) so I need to be sure that flashing an OOS img based on Android 10 will be safe to do as all guides I've found say its best to flash an img based on the same Android version already installed.

Also, I can't find an up-to-date guide on returning to stock using TWRP (or any other method for that matter). Can you please provide me with a link to one? Thank you.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] psychopac:
I'm don't really have a lot of experience with TWRP on phones with A/B partitions so I'm just gonna direct you to the method I use to go back to stock ROM.

https://xdaforums.com/t/op6t-latest-10-3-8-collection-of-unbrick-tools.3914746/

The above URL will take you to the unbrick tool's thread where you can find MSM Tool and the fastboot ROM package for fajita. As of this moment, the latest package available to flash is OOS 10.3.8.

The instructions for using the MSM Tool and the required drivers can be found on the thread posted below.

https://xdaforums.com/t/tool-6t-msmdownloadtool-v4-0-59-oos-v9-0-13.3867448/

If you plan on using this method, make sure you've backed up your entire phone, and have all the necessary drivers installed. Also, this tool will lock your bootloader when its done flashing the ROM.

Once the ROM is flashed, the first thing I do is install any remaining updates (if I want to run the latest update) using Oxygen Updater. When all that's done, only then I proceed to start setting up my phone for daily use.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] BassR9:
Hello everyone! The last time I tried to independently reflash my Oneplus 6T for the previous 17 version of LineageOS I broke the bootloader (despite the fact that I used the official manual from the LineageOS website) and I had to install an emergency update on OxygenOS.

Please tell me you could advise me to advise the instructions (someone from you did installing lately and can tell me) what to make step by step so that I do exactly the same thing that is told on your recommendation.

I found this tutorial https://xdaforums.com/t/guide-installing-lineage.4075955/

But here the author of the topic did not perform testing from OxygenOS version - 11.1.1.1

So I'm not sure if this will suit me

Also want to know if someone knows which version of TWRP is best to use?

Are there any difficulties installing Micro-G?

I have Oneplus6T(А6013 model), 11 Android version.

OxygenOS version - 11.1.1.1

Thanks for this, but I tried it and may have an even bigger problem now. I got an error that read "sahara communication failed..." and now my phone wont turn on at all. not to recovery, bootloader, fastboot.. nothing. Wont even indicate that its charging.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] psychopac:
Been there.

There are two possibilities.

1. The problem is temporary - If you can't get your phone to react to any button presses, leave it be for a minute or two, then try the flashing process again. If that doesn't work, plug it in for a few minutes and then try again.

2. The problem is a lot worse than it seems - As mentioned earlier, I've had the same problem in the past. I was trying to install a fastboot ROM using the MSM Tool and was stick with the same Sahara error. Tried all the drivers, multiple versions of MSM Tool but to no avail.

When all else failed, took the phone to OnePlus Service Center and the repair tech said that the motherboard is toast. Fortunately, when that happened, my phone was in the warranty period and they replaced the motherboard free of cost.

Couple questions as I have taken a couple months off from using Lineagos 18.1. I flashed it back on a week ago and am fully updated with Oxygen 11.1.1 and the 10.04 build of 18.1.

1. My call volume even at the lowest setting is very loud. Fix or workaround for this?

2. I cannot find a setting to change vibrate/haptic feedback for apps. For instance a game i play vibrates during certain activities in the game, such as scoring a goal, etc. Is there somewhere i am missing a slider for turning down the aggressiveness of the vibration?

Thanks!

Skipping audio issue.

Has anyone else had this? It's been happening for the last 2 weeks or so. Basically no matter that I'm doing, the audio skips/hiccups/lags for about 1-2 seconds every 5-10 seconds. It will do this with streaming audio, streaming video, local video, Google Maps navigation, ringtones, even Bluetooth-streamed audio.

I've updated to the latest vendor image, updated to the latest LOS build, and it happens whether I use a custom or LOS kernel. Makes no difference if I'm in wifi or cellular date, charging or on battery.

I did do a clean install of the OS and restored apps via TB and the problem persists.

Any thoughts what I can do to try and track down the cause of this?

Gentlemen I used latest TWRP attempted to flash LOS 18.1.zip here from OOS 10.3.7 and got stuck in a fastboot brick (I was able to get it back to 10.3.7). I have been researching how to get TWRP on OOS 11.1.1.1 but so far no luck, but when I do I want to ask will TWRP be able to install LOS18.1.zip? Shouldnt you be able to flash LOS18.1 from OOS 10?

Also my device is a 6T International conversion using MSMtool, I dont know if that makes things different in regards to flashing LOS but if it does please let me know..

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] gorman42:
Ok, so... I followd instructions from here: https://wiki.lineageos.org/devices/fajita/install

Got to this point:

After that the phone went into bootloop (I think that's what it's called). Since the guide states "With the device powered off, hold Volume Down + Power", I thought I needed to turn it off.

No amount of keeping the power button pushed turned it off. So I pressed power + volume up + volume down. The phone turned off. And now there is no way to turn it back on. I tried keeping the button pressed for a minute. Nothing.

What the hell happened?!?

EDIT

Ended up using the unbrick tool, which apparently worked (it's rebooting and the screen is on). Now I will have an Android 10 device and I will need to understand what the hell went wrong.

EDIT 2

I unbricked it. Re-updated to 11.1.1.1, installed recovery. I go to recovery but then once I reboot it enters bootloop. Is the Pre-Install instructions step supposed to be done once you get to recovery and before rebooting from recovery? Because at that point you cannot sideload or, if you can through adb it should be more clearly explained. I am now again facing the damn bootloop...

EDIT 3

Re-read instructions, got the Sideload from ADB thing that I was missing. Crossing fingers...

I successfully flashed the OOS version you linked, now did this at fastboot mode:

fastboot getvar current-slot = (got this result) current-slot: b

fastboot flash boot lineage-18.1-20210930-recovery-fajita.img

(got this result) Sending 'boot_b'... Writing 'boot_b'... Finished...

The first time I did this the phone restarted back to OOS10.3.9, the second time I tried it just stays on fastboot mode and doesnt do anything (the command results I show above is from the 2nd attempt...) I suspect this might be a slot problem, not sure..
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] DoggyStar:
Use latest recovery, that is 20211014, and also use same day os.

When you are fastboot mode, just flash boot like you dit it before. Then shut down phone and boot it straight to recovery using button volume down and power. Push the button long as you see text your phone and so on. Then release the button and you should boot to recovery.

And it's not the slot problem.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] retry0001-coffee:
Yes lots of people have. I flashed OOS firmware to my phone and am running fine. I'm pretty noob at android stuff, but not at linux. My only advice is that all the people failing seem to be trying to cling to TWRP. I say embrace the LOS recovery that they now bundle. Recognize that fastbootD mode in LOS recovery is not the same thing as booting to fastboot via adb. These are two different modes and only fastbootD mode via LOS recovery gives you the permissions you need to make things work.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Kurt Krummbein:
Hm, a current TWRP should also support fastbootd-mode. If not directly, it should be possible with this command sequence (from PC):

fastboot reboot bootloader

fastboot reboot fastboot

Now, TWRP should start in fastbootd mode ... if not, replace it with LOS-recovery ;-).

Ciao

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] retry0001-coffee:
Well you say that, but when I first tried to put LOS on my phone, I used TWRP too. I tried to enter fastboot via adb, got a different fastboot mode, and almost bricked my device too.

Go back to post #446 and read what that user wrote. You can go back a few posts to get more context, but that post explains it well. It should be stickied.

Note: If you opt to use Open GApps, they offer a variety of sizes of packages that include and overwrite different apps. We only recommend package sizes up through nano, as described in Open GApps Package Comparison. If you use a larger package, we can not guarantee that everything will function on your device, as in many of these cases our included apps are overwritten in favor of the Google App equivalents.

I have noticed a strange behavior concerning the LiveDisplay feature (my longtime favorite bug !). The color profiles work properly... except when "night light"* is ON. In night light mode, you can choose any of the profiles, you only get vivid colors like in DCI-P3 / Wide color modes. Standard or sRGB are not applied...

I'm using 18.1-20211018-microG-fajita built, I don't know if any later built corrects this. Can I report this somewhere ?

First of all, thanks for the ROM, so far so good. Good battery performance, pretty fluid, Safetynet passed easily with magiskHide + propConf, ...

The only bug I've found is that USB file transfer is not working. I've tried it on 2 windows computers and the device is not recognized as USB mass storage, I've tried on a Linux computer and it's working though. It's not drivers related cause using stock ROM or other custom roms makes file transfer works on windows.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] popy2006:
You can use substratum lite + nonavbar.apk (for ANdroid 11, which hides the navigation bar, floating here around on XDA) + FluidNG from play store to archive this. My wife is using this because she also wanted the OOS styled gestures back. Sometimes FluidNG doesnt work (when you get a call and phone is locked, also some situations i cant remember). but she is pretty satisfied.

-> for i just use the new gestures and love them now.

If you need more informations, just ping me here.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] gorman42:
Yes. I solved it that way. Changed the notification sound to something else and notifications sounds are working now. The previous sound was fine, when selected it played back with no problem. And it used to work. Don't know what messed it up.

Thanks for chiming in, I appreciate it even if I had solved it (and I should have written sooner the solution, as it might help others experiencing the same).

Hmmm... I see the FluidNG app. The fact it's no longer mantained doesn't inspire confidence but I could try it, sure (and thanks!).

I understand the nonavbark.apk thing, in order not to have conflicts with FluidNG (I suppose).

What is substratum lite for, though, in this scenario? I have zero experience with substratum. Zero, nada, zilch.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] popy2006:
Yes, it's EOL, but working in it's state.

Substratum lite (from PlayStore) is an theming engine which can load the nonavbark.apk and both together can hide the default android 11 navbar. I forgot, you need root (magisk for Substratum lite to work).

Just install it, open it, give root permissions, install the nonavbark.apk, reboot, open substartum again and load/install the nonavbark.apk in substratum lite. Reboot again, and navbar should be gone.

YOU MUST FIRST SETUP FluidNG to work, because otherwise you are missing navigation controls :-)
