Thanks for your work brother .. I have the McLaren edition, unlocked, rooted, and moved to Beta 2 .. can I use your v3 to fully return to stock McLaren or these files intended for regular 6T who want to taste/test out McLaren edition :)?

Remote session is not available until February. I talked to one plus chat last night and that was their answer.

Just have a question, if a normal OP6t has been flashed into a Mclaren edition OOS, is the WARP charger working at 30w? Basically the normal OP6t running normal OOS makes the WARP charger same level or even slow as the DASH charger.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
Never paid attention, should be normal dash. I did notice that the phone seems to charge much faster. May be something in the kernel. This is the McLaren edition dump. Maybe not with new updates.. I dunno..
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
**Update***

With every new version of oxygen os, users can maintain McLaren features by installing whatever the latest update is, installing via local upgrade, and then reboot to bootloader and flash the op1.img. reboot. Now u are updated with McLaren features still intact. U won't have to renable the fingerprint commands either.

Happy new year!

If and when OnePlus updates anything else McLaren specific, I will update the thread, but no promises..maybe ill make a magisk mod..funny how magisk is the new supersu and Xposed..but way better...

My afh has been updated with some fresh simple gapps. Courtesy of enzios repo and my beastly new anteragos install..

Dont drink and drive.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] null0seven:
I read that warp wont work on op6T with the same speed. It charges op6t a little slow than Dash charger.

And Dash charger on McLaren edition phone , same thing. They say that it's a small modification on the hardware.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Jacobddu:
I assume the scenario is WARP charger on normal OP6t flashed McLaren edition ROM. Then compare the charging speed between McLaren OP6t & normal OP6t (flashed McLaren rom).

If the same speed, means the hardware specs are the same, just some software limitation on normal version.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] null0seven:
No. It's electronic, hardware. And warp charge it's VOOC charge from latest Oppo phone, made by same people that makes OnePlus

Hello everyone .. I have the McLaren edition, and after updating to Beta 2, in a attempt to go back to stock I installed v3 here via fastboot in attempt to go back to stock .. and it seems the end result I soft bricked my phone .. I also tried a couple of other fastboot images available on XDA with the same result .. the only thing I can access now is fastboot .. any suggestions will be greatly appreciated .. I already spoke with support and the stock McLaren image will not be available until another week or so and they provided no guidance aside from that and asked me to stand still until then .. for me waiting another week, and possibly more, will be like forever lol .. luckily I have a backup phone .. nevertheless I am hoping there is something I can still do until then .. thanks in advance.

Have you looked for the dump of mclaren edition. It should contain the img files you need.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Duskycub:
I have the same issue and how would u install the mclaren dump what are the commands
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
Guys, for the 100th time this IS the McLaren dump. Only thing that would brick u would be an incorrect fastboot environment. This contains EVERY partition we are able to flash. Yes a dump includes a few more things technically speaking, but do u no good. They are individual device specific partitions we aren't even allowed to speak about here. So, that being said, rerun the flash all partitions fastboot.bat. not as admin. And there is a McLaren msm tool here:

https://xdaforums.com/oneplus-6t/how-to/mclaren-msmdownloadtool-rom-t3884585

I checked it out myself. It is legitimate. Works for Intl 6t and McLaren. Makes u Chinese variant I believe, but then u flash a oxygen ota that is newer via local upgrade and it works good. I always flash hydrogen builds overtop oxygen, I actually love them. The oppo market has faster updates than play.

So I can better assist, what is your install steps, and post a pic of your working folder.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
Also, since this ROM is a downgrade from beta 2, u would definitely have to fully wipe before flashing. This is a lower version.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
This is the dump and has everything to restore. Sounds like his fastboot environment is derped. He can't get any fastboot ROMs to go.

Hi [MENTION=9317968]jacksummers[/MENTION]

Kindly, I would like to clarify one point that to flash OP6T ROM then flash OP1.img from McLaren ROM to have all features?! Am I right?!

Thanks.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
Yep that's it. But u will not have McLaren live wallpapers, or fingerprint animation. U can enable the animation with a terminal. And the wallpapers, I think anoop figured that out..check his threads. U DO get everything copied into /op1. We just need brighter minds to get the rest working. This ROM was just to get OOS 9.0.9 out there and to see if everything from McLaren would work.. If u want the best experience, use his mod. Till I get wallpapers actually functioning right. But yes, op1 is all ya need.

Use an activity launcher app to make a shortcut for McLaren ar cam.

By the way, may you PM your nickname on telegram :o

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
I scrapped it, not really worth it...im building something better.. probably done with ports, just building roms.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
U dont use terminal in twrp, use a terminal app from within android.

su

Hit enter

Now u have McLaren animation

To change simply select another animation under fingerprint animations

I don't use telegram. I dislike chat apps

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Mulham82:
Bro .. What are the ROMs you're going to build?! If you can build PE, DU will be great!

You know you should create a channel on Telegram, so we test and have updates from you instead of checking from time to time xda :good:

By the way, can you create a normal ROM as a zip from OOS or H2O to flash it because I want to flash Pico/Nano Gapps this will let you have better performance and battery backup ;).

Thanks.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
I cant create a flashable rom zip with OOS cuz of the install procedure needs fastboot to flash both slots. U can still flash your own gapps. I use simple gapps on Android file host one folder up from this rom.im building something unofficial to make sure i still can do it lol its been a while. Then i will bring Screwd back. That was my goto. I really would like to build posp, i see big things with them, they are on the up and up.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Mulham82:
Dear .. I have tried "Simple Gapps", but after rebooting you still see stock gapps from OOS. You can create a normal zip by managing the updater-script to flash the ROM on both slots.

Thanks.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
Yeah,and even so, it will also have gapps already. It is built into oos. This is oos untouched. I didnt add anything or remove anything. This is just how it comes buddy..debloat the apps u dont need.

Weird man, flash just the op1.img from the rom and i bet u get it back. Fingerprint u gotta enable with a terminal. Wallpaper hasnt worked for anyone. I would advise against relocking your bootloader cuz soon as we have an update u will have to update, unlock, flash op1 again then relock.

Cuz u cant go backwards with firmware without a full wipe. My guess is you were on oos 9.0.11. this rom is 9.0.9. u gotta format or u wont boot. Next time, just stay on oos 9.0.11 and just flash the op1 img from this rom. Thats the mclaren stuff. We didnt know back then but its all u need

Edit.. and u broke verity and cant boot. Format, then try to boot. Then in a terminal su reboot "dm-verity enforcing"

Can someone verify this i am running a op6t rooted with twrp and by magisk installed the McLaren bootup logo but have the Orange unlocked bootloader message before it goes into McLaren bootup logo (all works fine) but for to get rid off the Orange triangle i need to relock the bootloader with a original McLaren oxygen os firmware.

Otherwise when i relock it and dont install everything as in original state i Will get a hard bricked phone and when i set it info original i loose the bootup logo from McLaren.

Thanks OP for helping me fix my OnePlus 6T. Long story short, I was playing around with unlocked bootloader, custom kernels, 9.0.9, 9.0.11 and Open Beta 3 and bouncing between slots and somehow got it in a bad state and it wouldn't boot up. I ended up using your guide to help me get 100% back to stock 9.0.9 which the phone came with. I noticed I got the boot animation and the fingerprint unlock animation but no wallpaper, I think I'd seen it mentioned a few times here. I then let it upgrade to 9.0.11 via the OTA update and it seems to running perfect now.

Side Note: It's funny, I have ElementalX kernel installed and I also have the latest Magisk version installed. It passes the SafetyNet check in Magisk. I downloaded 5 other SafetyNet checks from the Play Store and it passes all of them. I can see and install Netflix from the Play Store (I heard netflix is sensitive). Google Pay is working. But I loaded Pokemon Go (don't judge me) before my bike ride and within a minute of being logged in, it kicked me out and showed a message about my device or Os not being compatible with Pokemon Go, somehow they've detected the phone's been modified. It's just funny that it can fool banks, netflix, google, etc. but it can't fool a silly video game.
