If anyone is having issues with Google assistant not having the screen off detection, I had to re-flash gapps to fix it. Opengapp nano is required for that functionality, but it wouldn't flash on my LineageOS 18.1 OnePlus 8t, so I originally flashed pico. Which meant assistant was there, but not fully functional. So I flashed the Mindthegapps Android 11 arm64 package over that, and it works fine now.

I just unlocked my tmobile 8t and am running stock 11. do I need to back anything up like persist.img before flashing? I jumped the gun on my 7t mclaren and ruined the finger printer reader. trying to avoid that! thanks.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Shidapu:
Just follow the guidelines for installing and you should be good.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] OhioYJ:
While I agree there is little risk following the instructions... There really is no reason to not back up your EFS and Persist. Especially as there is "no" way to recover the EFS if something goes wrong later, and they are unique to your device. You should never need them, but if you ever do, you'll be glad you have them.

From my write-up (if it helps)

sudo adb shell

dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img

dd if=/dev/block/bootdevice/by-name/modemst1 of=/sdcard/modemst1.bin

dd if=/dev/block/bootdevice/by-name/modemst2 of=/sdcard/modemst2.bin

exit

sudo adb pull /sdcard/persist.img /home/mint/Desktop

sudo adb pull /sdcard/modemst1.bin /home/mint/Desktop

sudo adb pull /sdcard/modemst2.bin /home/mint/Desktop

I originally used the broken TWRP to do this.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Brasscat82:
I have an issue with the latest LOS update.

I've installed TWRP and Lineage on slot A, and then proceeded to restart to recovery flash TWRP, gApps, and Magisk on slot B. Everything was running super smoothly until I downloaded the update, and flashed it to slot A. When I reboot, it boots to the LOS boot animation for about 40 cycles, then reboots.

I've reflashed Magisk (B) and TWRP (also B), but I still keep getting the bootlooop. Can anyone help me fix this without wiping my phone again? THANKS TO THE WONDERFUL COMMUNITY!!!
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] thefanum:
I used the copy partitions zip when flashing LineageOS so they would all be the same, as instructed by the official documentation. I also used Lineage recovery and adb sideload. I don't think flashing with TWRP works.

Hope that helps
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] dagustl:
Try to switch the active partition.

Check in fastboot mode which one is active with

fastboot getvar current-slot

if you are on "a" then change the partition to the B-Slot with

fastboot --set-active=b

if you are on "b" then change to the A-Slot with

fastboot --set-active=a

and reboot the phone.

Good luck.

Question (sorry if already answered) : will (y/n) lineageos 19 for 1+8t require oos 11 firmware or oos 12 firmware (or maybe two roms will tmp be available) ?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] thefanum:
I don't know for sure, but I would guess either 11 or 13. 12 breaks all current recoveries and won't allow you to flash anything.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Dior DNA:
nevertheless some custom ROMs offer (tmp) both OOS11 and OOS12 right now. And, will there ever be an OOS13?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] thefanum:
Oh yeah, there is absolutely going to be a 13 for the 8t. But I have no info beyond what I already said.

Just speculating, and don't want to speak for the excellent devs, but if I were to place a bet, it would be 12 firmware will be required. The hang up has been waiting on OOS 12 sources from what I understand. Next if you look at similar devices, OP9, etc, OOS 12 firmware is required for LOS 19. Finally as long as LOS recovery works, doesn't really matter what happens with other recoveries, unfortunately.

My bet is on the OOS 12 firmware.

It appears OnePlus still has not released OOS 12 Kernel source. (<-- Github link)

See these issue links in particular:

Where are the DTS in the OOS12 kernel source?

GPL Violation: OOS12 kernel_oneplus_sm8250 sources have not been released

I linked to two of these issues, there are a ton of them actually, they are scattered across Github, across many devices. Then again across many Reddit threads. OnePlus apprently doesn't care about GPL and doesn't care about releasing the code as they are supposed to.

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] OhioYJ:
That's what I linked to above. However, I'm not sure I would called it "released" when what they "released" was missing so many things. Then even after it was pointed out, and they've slowly added in missing things, yet things apparently are still missing?

Is the brightness sensor fixed?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] xstefen:
OnePlus released GPL parts of the kernel source already. They do it in the most minimally legal, maximally scummy way possible. They're so far gone from the ideals that made them successful in the beginning, its sad. Hopefully people will stop giving them money

Edit: Seems like they unpinned the repo and started ignoring that too, https://github.com/OnePlusOSS/OpenSourceReleases/wiki/OnePlus-8T , nevermind. Burn em to the ground
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] OhioYJ:
What does that do for you? Oppo and OnePlus are the same.

Best I can tell most Oppo devices, with a few exceptions don't get much development. Without Lineage support, I have zero interest in Oppo.

Probably because people are essentially still complaining about it.... It's kind of like asking for ETAs.

Lineage Stats. The 8T is fairly low on the list compared to the say the 5T, or the 6T, or the 9, 9 Pro, other devices that have been mentioned.... I'd say be happy with the support we've got.

There's even a donate in the OP, if you really want to say thanks. Just make sure it's it's a donation / thank you, not a bounty for a LOS 19.

For now we got LOS 18 we, at least it works well.

Hey Luk , I have S12 which is Color OS and since it is COS , Oppo , and Vivo lock there bootloader and there is no Custom roming for these 2 brands or unlocking the boot loader, is that what's happening to the 8t , 👋
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] LuK1337:
No idea what you're talking about.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] thefanum:
Are you asking if the bootloader was retroactively locked? OnePlus does not lock bootloaders. Never have. The cell carriers who offer OnePlus phones do, but they also offer unlock codes when certain criteria are met.

Not to mention, that's not how bootloader locking works. If the bootloader is unlockable, it will be that way out of the factory OR it will be unlockable, but require an unlock code from the manufacturer to accomplish the unlock. So that they can enforce certain stipulations (phone paid off, phone bill fully paid etc).

So the only way a company can make a previously bootloader unlockable phone no longer unlockable, they have to start out as the models that require an unlock code, and then stop offering the unlock codes. But they can't make a phone, which has never needed an unlock code (like every non carrier OnePlus), no longer bootloader unlockable. As far as I'm aware.

And judging by the response huawei got when they stopped offering bootloader unlock codes on their previously unlockable phones, I doubt any companies will be trying that again soon.

I am no expert, and I'm not a developer, just a phone hacking enthusiast, so take this next theory with a grain of salt. If I had to guess why the 8T is not getting a lot of development attention, it's because developers don't care about oneplus like they used to. People often focus on the unlockable bootloader, and forget that that does zero good if the device doesn't have a development community who wants to invest hundreds of hours into making awesome tools for us. Like custom recoveries, custom firmware, and every other aspect of the ecosystem that the company themselves won't create.

In the beginning, one plus was very developer friendly. They work with the custom firmware community, and even when they stopped working directly with the community they continued to be supportive of it. None of that is true any longer. They are now an active hurdle to custom firmware development. They are not posting the code they are legally supposed to, and when they do it's often late and incomplete. Which means the developers have to work 10 times harder to make anything work, or they can just develop for pixels or other more supportive brands.

Unless things changed dramatically at oneplus, this is just a taste of how bad things will get. So enjoy this, it's probably the best our oneplus devices will ever be, custom firmware wise. It's all down hill from here
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] OhioYJ:
Yeah, I had two Honor 5xs, got unlock codes from Huawei, also last Huawei devices I ever bought.

The worst part is I don't think OnePlus realizes the extent of what they are doing. I realize "enthusiasts" that run custom software are a very small percentage of sales. It doesn't matter that most of us have a stack of OnePlus devices. However how many people around you have you recommended a OnePlus device to? Just recently I had my mom order a new OnePlus device, she just runs OOS, but it was a cheap, decent phone for her. As tech enthusiasts, people generally ask people like "us" what they should get. OnePlus can alienate whoever they want. However if the tech crowd switches brands, OnePlus's already pretty small slice of the pie is probably going to get smaller...

/off topic rant....
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] thefanum:
Yep, I'm offering free LineageOS conversions for the 5 people I know personally who were dumb enough to listen to me about buying OnePlus phones. Seems like the least I can do.

And I can't back this up with any figures or facts, but I really think we built OnePlus. Yes, we're a very small fraction of the user base, but between all the free publicity we collectively gave them online, the cool things we did with the phones that got them major publicity, and the personal recommendations we gave out to people who trusted us because we are often the only (or one of a few) people in their lives who know tech, I think OnePlus is one of the few times we helped change the technology industry directly.

And all we have to show for it is this polished turd.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] card13:
@OhioYJ and @thefanum Only slightly going to keep this Off Topic going. I agree OnePlus is no longer Dev friendly like they used to be, and there are many reasons to support this conclusion which includes the fact that the Kernel Source Code issue started in OP5 times (Example of how long this exact subject has been an issue https://community.oneplus.com/thread?id=457370). Also enthusiasts did build OnePlus, after all OnePlus' Official OS was CyanogenOS which was the corporatized version of CyanogenMod (you can read the history of that mess here https://www.androidauthority.com/cyanogenmod-lineageos-654810/).

Forgot to thank @LuK1337 for his hard work all these years on the OnePlus phones I had to support for my family and myself.

sorry to perpetuate the rant - perhaps a question for LuK1337 and others who are considering their next phones - which one should we be preparing to move to?

my concern is whether pixels are probably even smaller in production numbers and dev community? is there any easy way to compare the development activity by brand and over time (eg github profile)?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] card13:
@ewong3 I can confirm the Pixel 6 Pro (that's what I moved to from here) has a slightly smaller XDA footprint than the OP8T did. But in terms of how long it is actually taking to get to a point of really starting to move, I'd say it's at the same point OP8T was at its' peak. As for non-subjective ways to tell, my guess would be a week study checking each day to see how much it has grown over the last 24hrs, that's usually how I do it with just released phones.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] thefanum:
I wouldn't trust any article that lists a Samsung phone as a "great phone for modding" without significant disclaimers. Samsungs can sometimes be unlocked, but it's always the crappy processor, non US/CAN models, or a paid service. Both have significant drawbacks. And last I checked, the dev community for Samsung devices is terrible, as Samsung intentionally killed it off when they started locking bootloaders after the note4.

The real answer to your question is probably there isn't a true replacement for OnePlus devices, modding wise. The Essential phone was supposed to be, but flopped immediately. The Nothing phone is supposed to be, but I'm not super optimistic.

Pixel phones are pretty much the only alternative. They have unlockable bootloaders, timely kernel sources (I think?), and a good development community. Unfortunately I'm not a fan of the hardware, but at least there's a backup plan.

There's other hackable phones. But none that hit that sweet spot that OnePlus phones used to.

And yes, you can check the actual amount of development being done on LineageOS behind the scenes, but I've never found that to necessarily correlate to the actual health of the development community. I think checking here on XDA by phone model is probably a better way to get a feel for the development community and their investment in said device.

Personally, I'm going to ride my 8t into the ground and reassess in a year or two. Hopefully things will have improved for any brand/device by then
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] LuK1337:
i t

I honestly don't recall OnePlus ever being dev friendly, at least during the time I've been using their devices, but ok. To me, basically nothing changed, except kernel source takes half a year to get released. But at least OOS 12 blobs are easier to work with, I guess.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] ewong3:
alternatively xda gives good idea of dev activity:

just now vs google:

so indeed, p6p is the top phone to go for, but op9p/op8p/op8t also not bad - perhaps all op needs to do is just don't release too many variants to dilute its own dev community resources!
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] thefanum:
That's fair. I knew things started going downhill when they killed the cyanogenMod collaboration, but it sounds like it was a faster decline than I realized. And I knew it was over when they stopped sending free phones to devs.

Few links from the Lineage Wiki that maybe handy:

Update firmware on kebab

Upgrade to a higher version of LineageOS (e.g. lineage-18.1 -> lineage-19.1)

Install LineageOS on kebab
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] thefanum:
Nevermind, I spoke too soon. Lineage OS 18.1 is still periodically forgetting the default launcher. At least on the new update it has stopped defaulting to trebuchet, and started asking if I want to select Nova or trebuchet when it happens. Which is significantly less annoying.

Would still love a fix, if anyone has any ideas.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] Dior DNA:
What a relief ... Kudos @LuK1337 !

Finally a 1+8T OOS12 firmware based open source custom ROM I can seamlessly build myself.

I was running Nameless (which is not open source) and I tried building AICP (but failed, which most probably is caused by my somewhat atypical environment).

But LOS ... : I can build just fine ... the documented build recipe is accurate.

Previously I could also build 1+8T PE+ A12, but then, that ROM is still OOS11 firmware based and no longer maintained...

On any device (computer, router, mediaplayer, phone, tablet, whatever...) I own I prefer to run software I (as somewhat n00b) can build myself. This, for me, is proof of well developer maintained and well developer documented software.

LOS 19.1 is my only and also best up to date choice for 1+8T device today.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] thefanum:
Ok, so I'm loving this ROM. I am dealing with two minor annoyances that are apparently too broad keyword wise to Google, so I'm hoping someone in here has a tip.

1. LineageOS keeps forgetting my default launcher. I use Nova, fully up to date, and it sometimes offers to let me choose between it and trebuchet when it forgets, and sometimes just defaults to trebuchet. No matter how many times I set Nova to default, it still forgets within a day or two.

2. It's behaving like I hit the back gesture multiple times, using gesture navigation. Even when it's clearly one single gesture. It's not consistent, and seems to happen at random, but works as expected, most of the time. It happens in all apps, and within the OS itself.

I've tried using all three different "back gesture" sensitivity options. Didn't seem to effect anything.

Thanks in advance

Hey,

I recently upgraded from 18.1 to 19.1 and it looks like usb otg stopped working. I'm relatively certain it previously worked for me on 18.1.

Currently if I try to connect a usb flash drive or a wireless mouse the phone does not respond to the connection at all.

Can anyone confirm if it works for them on 19.1 (I'm on the latest build)?
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] thefanum:
I'm trying to compile 18.1 from source, and I've got everything working, pulled blobs from my existing LineageOS 18.1 OnePlus 8t phone via adb, but it's still saying there's stuff missing at compile time (blobs).

Should this be working? Or should I just find a stock firmware file and use the extraction method? Or is there a repo with them somewhere?

Thanks in advance!
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] optimumpro:
You don't need to pull anything from your device. Just follow lineage's build instructions, and 'breakfast' etc. commands should create local manifests and pull all necessary device tree, kernel and other dependencies including vendor blobs.
