[Guide] Root US OnePlus 8T KB2005 Unlocked

[g96818]

oneplus is brutal North America Ota's are always late. same thing happened with op6t 7t etc

It's not super late. The roll out started last thursday and is done in stages so the servers aren't overloaded. The OTA popped up on my phone 2 days ago.
The 11.0.2.3 OTA was skipped for NA cause of all the issues the IN and EU users were reporting, which is why this 11.0.3.4 came out so quickly. IN and EU are the guinea pigs.

I think he was referring to making the full OTA available instead of incrementals.

You're referring to the full ROM. The incrementals are OTA.

Keinta15 is right. Only incremental OTA. Better than nothing.

Yeah, it didn't directly solve my problem, but as it turns out it indirectly solved my problem because I took another look at the broken TWRP method and figured out what I'd been doing wrong. If anyone else is struggling, it's worth making sure you're using the boot image that corresponds to where you got it...

fastboot --set-active=a

or

fastboot --set-active=b

Making sure I was running on the right partition finally got me rooted where all my other attempts would ended in bootloop. Probably a dumb mistake to you guys who do this stuff all the time, but I pretty much only open ADB when I buy a new phone, and that only happens every couple of years for me. Unfortunately, I've gotten used to having root access and all that comes with it.

I can finally use my new phone like I'm used to. Thanks to all you XDA regulars who let tourists like me in on the secrets.

Can anyone please provide the stock boot img and hopefully magisk patched boot image from 11.0.1.2.KB05AA?

It looks like you can't upgrade to the newest incremental I got today if you switch back to the stock boot image from KB2005_15_200918 after being on KB2005_15_201015I. I have tried all other methods I know so far with no success and can get the phone booted but no wifi.

I will keep trying some other methods but if anyone is able to pull and post the stock boot img and patched from KB2005_15_201015I, I would really appreciate it!

Copied from my post on the other main thread for rooting. I didn't realize I was not on this one, but just in case...
(Moderators delete if needed)

For the US KB 2005 Variant update that released today (11.0.4.5.KB05AA), I just repeated the process for the last update and had to no issues. They key is being patient!

To get the update applied
From elevated prompt using adb
Adb reboot bootloader
Fastboot flash boot stock-boot.img - Found here
fastboot reboot

Let your phone reboot and then download and install the new update
Complete and restart phone again
Once restarted go back to prompt for ADB...

adb reboot bootloader
fastboot boot patched-boot.img - Found here
fastboot reboot

The phone took forever to boot (Maybe 5-10 minutes), then seemed to do a quick reboot or boot loop automatically but did not lose the patched boot image I just booted with.

After it was finally done booting, I simply opened up Magisk and did a direct install and BOOM, rooted on the new update!

I hope that helps anyone trying

Uninstalled magisk and still cant install latest update. Neither from system or local .SMH

Gotta lock bootloader to install incremental ota's sometimes..not sure why. Even just unrooting isn't sufficing anymore

 

[g96818]

I updated fine by just unrooting. https://forum.xda-developers.com/showpost.php?p=83940123&postcount=210

 

[dreisus]

I didn't lock it the last time I did it. All I did was remove root

boot.img

Here's a semi-broken TWRP that allows su access through adb: https://drive.google.com/file/d/1dRXJj7HZcqlNsHlVcNH0qR3sNx_uBA__
DO NOT FLASH, ONLY USE WITH BOOT COMMAND!

fastboot boot recovery.img
adb shell
dd if=/dev/block/by-name/boot_a of=/sdcard/boot_a.img
dd if=/dev/block/by-name/boot_b of=/sdcard/boot_b.img
exit
adb pull /sdcard/boot_a.img boot_a.img
adb pull /sdcard/boot_b.img boot_b.img

I borked my boot_a by flashing it with boot_b (boot_b was broken on my device), so I was unable to obtain a working boot_a.img. If someone could kindly share their KB2005 boot_a.img that would be nice.

is there a NA 11.0.4.5.KB05AA full ROM available for download?

Sadly no, there's only been incremental

Thanks to @TheUnkn0wn:

His info. His quote. Xda can't figure out the quote w/code scenario, my apologies:

adb pull /sdcard/boot_b.img boot_b.img

You are the man! thank you!

Edit. Xda ruined the reply. I did not.

Hi Sir, i'm confused

We need 2 boot images for rooting ? ( boot_a.img and boot_b.img ) wich one do we need to patch please?

The file recovery.img must be copied in computer adb folder or directly in the smartphone please ?
sorry i'm new with One plus smartphone.
Thank you

Have you guys retained widevine L1 after rooting with the latest update on the 2005? I accidentally flashed the BA rom on our phones so I had to MSM back to AA, update to the latest, then bootloader unlocked and rooted using the stock boot posted here. Widevine is still L3 for our two phones.

Wtf did I permanently screw up our phones by flashing BA? Thought MSM would restore it. Wonder if it's the custom kernel or some other factor, should've checked widevine status before rooting and after restoring AA.

i followed Wykillin post using the broken TWRP on both OS11 0918 build and OS11045 update and i used magisk patched boot a on the first one, then i flashed original boot.img so i can update and then after update i had to use magisk patched boot b. when i used patched a it just boot looped. when i used patched b it booted right away. hope this helps clarify things a little or helps someone. thank you for all your hard work guys!

$$$Who can i compensate thats responsible to make this happen on the 8T????$$$
