Return to stock/rooted? - OnePlus 6T Questions & Answers

I'm currently custom rom/root/unlocked bootloader.
I'd like to return to OOS with root and unlocked bootloader.
Is it as simple as flashing a stock OOS image in twrp and then flashing magisk and twrp?
Can anyone spell out the order of the steps for me? I've searched and can't find any answers to this noob question. It's crazy, I can flash custom ROMs all day but my brain farts on returning to stockish lol.

Note that I'm using an originally TMobile variant, flashed to international.
I would be fine with using MSM and then unlocking my bootloader again, but would I use the standard MSM or the patched this time?

Bump would really like to go back to stock. Which MSM tool would I use being this was a tmo/intl conversion?

Are you trying to go back to the TMO version or international? If TMO use regular TMO msmtool, unlock bl, flash or boot twrp and flash magisk for root. If going to international.. same but with patched msmtool.

I would like to return to international. Basically, I'd like to get myself ready to take the 10 update when it releases.

Best and easiest way would be to use patched msmtool from the convert TMO to international thread, unlock bl and root again. You will lose all data.

Can I flash rom with the root without unlocking bootloader method?

I read somewhere that you still need to unlock bootloader to flash custom recovery and rom. But in this thread, it looks like you can flash TWRP recovery, so I'm a bit confused.
In layman's terms, tenfar somehow got ZTE's signature key, which allows us to flash TWRP so that the phone thinks it's official and from ZTE. His tool can also flashe a modified boot image that already includes systemless root. However, his tool is only built to modify recovery and boot. Custom ROMs replace other partitions, so for now an unlocked bootloader would be required to flash a custom ROM.

I haven't decided yet or not to buy one, will this work on the U.S. version?
Is the bootloader unlocked on the U.S. version?
Thanks

OTA update when rooted

My phone is unlocked and rooted. It wants to download the OTA but I know that Motorola says on their site you will have problems with the OTA. Should I download it or Should I flash a ROM.

You must be PURE stock to take an OTA update, or it will fail and bootloop... Flash a rom if you wish.
What i did was make a back up of everything just incase and then look up the ota version on your phone and get it in the rom section and look up twrp flashable OTAs and just flash it. you might lose root but its easy to get back if you flash magisk again.
You can found the right guide here:

Of the current version? lol, no, we wish... we are averaging 3-6 months behind OTA releases for full ROM images, if we get them at all. Moto does not officially provide them, so they have to be leaked somehow, and sources are completely dried up yet, but it's getting there. :/

You can't be rooted with a locked bootloader so your question is obsolete.
You can apply to OTA with an unlocked bootloader.
You can't if you're rooted or changed anything else in /system or /vendor.

Thanks for the reply. Very clear! Please I need more help. The thing is...I don't want the oreo ota right now. This is my mother's phone so I don't want any problem. Nougat is just fine for now. So I need to stop the upgrade notification spam. I believe I must unlock BL, then root, then freeze the upgrader app. Is that correct? I can't force stop the app. That's for now.
I've read bad reviews about oreo battery drain and other stuff. That's why I'm trying to avoid it.
If someday I want it, maybe will install some rom.
Thanks bro.
EDIT. Does this make sense? Or should I stay stock everything and take the ota/ignore the spam everyday?
EDIT 2. Another question. What happen if I take the oreo ota, and i don't like it. Can I unlock BL, root, install some nougat rom, as a pseudo downgrade?

Oreo ist absolutely fine, no problems with it.
I haven't heard of any issues like increased battery drain, for me nothing changed at all regarding battery and the rest is also working flawlessly.
It would be a lot of action to unlock and root the device just to stop the updater service.
If you don't have any other plans that need root privileges I recommend just taking the OTA (s).
If you want to run another ROM later you can always unlock the bootloader, install TWRP, root the device and install any kind of custom ROM, Nougat, Oreo or Pie. There are also TWRP flashable stock firmwares which make it easy to move between different stock versions.

That's good. A pseudo downgrade is possible. Thanks man. I'll think about it. And yes, the root privileges is just for stopping the updater.
Cheers
EDIT. Man, are you sure about this? Taking the Oreo Ota, and in the future unlock BL, root and install whatever rom?

Yes I am.
Just check some of the custom ROM threads, there are some that need stock Nougat as base but the most of them need Oreo. For custom ROMs there are no up/downgrading problems, that's only the case for stock firmwares.
And as said above, there are TWRP flashable stock builds that doesn't have these problems too and will bring you to whatever stock firmware you want, not just pseudo. (Here:
https://forum.xda-developers.com/g5...o-twrp-flashable-stock-builds-coming-t3830482 )
So if you're on stock Oreo after unlocking the bootloader and flashing TWRP all options are open for you. Just don't forget to make a full nandroid backup incl. EFS and persist before you flash anything.

What happens to root/TWRP when you upgrade a rooted LG H91810j to H91810k or H91810p?

Has anyone tried upgrading a rooted LG H91810j to H91810p? Did you still have root afterward? What about TWRP? I am concerned about losing root and losing the ability to roll back because of their "anti-rollback" mechanism in 10p.
Optional back story, for the curious:
I bought a refurbished LG V20 that was running software version H91810k out of the box. I immediately tried to root it with dirtycow, but dirtycow does not work on 10k. So I downgraded to 10j from 10k using LGUP, and then successfully rooted the phone with dirtycow. I then installed TWRP and then LineageOS.
Unfortunately, I just don't feel like LineageOS is where it needs to be for me on the V20. I lost a number of features, such as (1) the second display, (2) ability to use BOTH cameras on the rear, (3) quad hi-fi DAC for superior audio, (4) automatic wake/sleep when opening and closing my phone case, (5) encryption (!!!!).
I feel like there are just to many things missing, so I think I want to go back to the stock ROM, but I would like to stay rooted so I can at least get rid of the bloatware. Is this possible or am I going to lose root and TWRP via one of LG's updates?
You can keep root on stock rom but flash one thats 10k if you flash one that's 10p and you wouldn't be able to back to anything pass
10p. Weta has a 10k version look in there thread for details and instructions

I understand not being able to rollback/downgrade after hitting 10p, but let's just say I decided to upgrade to 10p+ anyway. Would I still have root and twrp?

Right, but I'm talking about being rooted without a custom ROM, i.e. running the stock ROM while rooted and having TWRP. Can I upgrade to 10p and beyond, and at least keep root/twrp, even if I can't roll back or install anything else?

What firmware are you no right now
1)Get 10i root it install twrp
2) there's a flashable 10r somewhere don't have the link right now put download and flash via twrp 10r is the newest update I believe.

Technically I'm running LineageOS (14.1-20171226-NIGHTLY-h918) but I want to go back to stock rom WITH root/twrp, because I lost a lot of features like second display, dual-rear-camera, quad hi-fi DAC, encryption (etc). I just don't think LineageOS is ready for this particular phone, for me. I am planning to revert to stock rom H91810j (re-root if necessary) and then upgrade to the latest stock rom, if I won't lose root that is.

Just saw your edit. So it sounds like the best way to upgrade is to flash it via TWRP rather than install it via the OTA updates? Can you (or anyone else) confirm it stays rooted when done this way?

Yes update via twrp, you keep root
You upgrade past 10k and you lose the ability to ever root your phone again in case you screw up and have to flash a KDZ.
Your choice.....
-- Brian
I have been rocking 10k just fine. There is support for a custom stock kernel. Personally, upgrading to 10r is not worth the risk, especially since there is nothing really new besides sercurity patches.
Well, I ended up flashing H91810r as per this thread and I am happy to confirm I still have root. Just thought I would post this for anyone wondering the same thing. Now I just have to remember to only update by flashing via TWRP, moving forward.
Pretty much just like everyone else here has said, always update via twrp. Never take the ota update when you're rooted. And didnt you make a backup? Why not just flash back to your original stock rooted room?
You mean we can flash Oreo 8.0 kdz and still have root intact?

Read the posts, NO. Flash a zip from a thread for your variant that's labeled as twrp flashable.

OOS 9.0.9 rootable yet?

Has anyone with the McLaren tried rooting or custom recovery yet? (Not talking about custom roms) The help guides currently come with verbage indicating 9.0.5, 9.0.6... etc, not 9.0.9 which this version shipped with.
I've unlocked the bootloader and am hesitant on the next step. Can anyone that has rooted link/state their process in order to assist weaker individuals like myself.
Thanks

Install TWRP and flash Magisk 18.
That should give you root.

Well yes that's normally how you do it but... and this is what I'm talking about... In order to install twrp, I'll need to fastboot boot the 9.0.9 stock boot img. The unofficial twrp for 6t only lists up to 9.0.7 of these imgs.
I might be wrong but I'm pretty sure I don't want to use anything but the exact version my phone is currently on (9.0.9).
Also, yes I'd be willing to pull files after I get rooted.

Sweet! Can I ask what img you used to boot into twrp initially? I'm assuming it matters because different versions are always listed.

Ah ok. I was doing it wrong.
I'm now set. I booted the twrp img from that post you linked and after getting into twrp, I flashed the installer followed by magisk.
Thank you guys.
There is almost no differences between the Mclaren 9.0.9 or the Int 9.0.7 minus the boot animations etc. The 9.0.9 is actually a earlier built date then 9.0.7 i dont see why it woulnt be rootable etc just like the normal 9.0.7

LG v20 (Verizon Help)

So I just bought a verizon LG v20 which has 8.0.0 on it. Simple question. Can I still downgrade using upercut and LGUP and then use dirty santa. I found the correct Firmware on lg-drivers and have it all ready and set. Some posts are saying that you can some people say you can't downgrade. I am just trying to figure out which is right. YES I searched multiple posts...
1. Can I downgrade when the phone arrives?
2. Can I still use dirty santa when I downgrade?
3. Why do some say patched and some say not? Is that because some models firmware are non-downgradeable?

Yes you can downgrade, probably only need to use the regular LG up, downgrade to a security patch prior to Dec 2016, follow the dirty santa instructions, flash updated twrp, within twrp standard wipe, format data, flash rom, flash magisk

Its that easy?
Yes. But I'll suggest before hand updating to the firmware version of your choice, and dumping it with LGUP (same tool you use to flash firmware packages). There's a lack of flashable stock ROMs for the v20 variants, so you'll be stuck on an ancient firmware version after rooting. Once you've flashed the DirtySanta engineering bootloader, you can flash back part of the dump (minus aboot and recovery), allowing you to keep TWRP/Engineering Bootloader while still having the system version of your choice.

Yea, but those updated stock custom build also pack a bunch of other crap you may or may not want. Its much better to start from fresh, do your own debloating, then pick and choose what you want. There's also the side benefit of not having to deal with AFH's godawful download speed. The VS995 has stock KDZ so restoring from stock isn't a big problem, but having your own dump on hand let you get back to the latest (or close to latest) system update and skip 2-3gb of OTAs

I just want a rom like Lineage OS or something that allows custom sets for my device. I am getting confused? just flash this rom with lg up, then use dirty santa, then install the rom correct? I haven't rooted since my nexus 6p since vzw locks the pixel and pixel 2 xl bootloaders -_- ... attached a screenshot of the rom.. its got 3k downloads and is marked 2016-12-24 3691(downloads) SO I assume I flash this first. then do the dirtsanta exploit? My last question is how do I install roms with these newer devices? Do I format everything(I got an sd card) and just keep the sd card clean? Would love some info!
Heres the link to the screenshot I tried adding. https://lg-firmwares.com/lg-vs995-firmwares/#tab=firmwares

You have to install Magisk/SuperSu to keep TWRP, otherwise the system will replace it with stock recovery everytime it boots. If you already have the Engineering Bootloader installed by following DirtySanta up to Step 3, just reboot into fastboot (hold volume down while phone is off, plug cable) and reflash TWRP with fastboot.
