Only reason I use twrp is so I make sure twrp and root survive each OTA I flash. But if you're only rooted, you can temporarily uninstall magisk for OTA and update and restore.
[OnePlus 6T  Guides, News, & Discussion] contesauce:
Man I can not get my phone to take the beta 2 zip via TWRP. I flash it, reflash TWRP, flash Magisk and it's still on beta 01. I follow OPO instructions to completely uninstall Magisk, then do the steps and still nothing. Same thing happened when I installed Beta 1. It would only take if I flashed via OTA local. What am I missing?

Don't tell me it's because I need to swap partitions after installation, if it's that simple I'll slap myself.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Just do the local upgrade and manually reflash root after, twrp is probably being buggy again.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Local upgrade does change a few criticals, I believe addiso got into all the details and threw caution like I had mentioned in being wary with future updates, something changed as of .7, which allows us to local upgrade .7-10 so far, we don’t receive OTAs, but we can install full roms via local upgrade, advantage of local upgrade is speed, it will remove magisk and twrp, if you’ve got a modded system, then you’ll need twrp and magisk to adjust to those mods to boot, if not then you don’t need those, another advantage is bootloader locking, since that restores the device to full secure boot mode, if you decide to bootloader lock, let the forum test updates before you attempt to install them, since we don’t know if OP decides to change things again and cause a mismatch.
[OnePlus 6T  Guides, News, & Discussion] :
Flip to opposite slot.
[OnePlus 6T  Guides, News, & Discussion] contesauce:
Thanks I did try that multiple times.

[MENTION=323462]Dark[/MENTION] I did both a local upgrade and TWRP flash. Whenever I flash it just boots back to recovery, then I have to reload TWRP, unless flashed in TWRP and then it just brings me back there. I have to flip back to my A partition and boot up Beta 1. I think something in my B partition is hosed, so when I get home from work I'm going to do a complete wipe and install stable fresh, then see if I can take the beta 2 update, or just stay on stable for now since there really isn't any feature in the new release that I use anyway.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Did you root your alternate slot that won’t boot then try booting again?
[OnePlus 6T  Guides, News, & Discussion] contesauce:
Here's my ending process, after trialing all the normal ways.

I'd flash the OOS update in TWRP on whatever partition it was on. Flash TWRP, then flash Magisk, flip over to the other part. and flash Magisk there too. Flip back to the other partition and reboot. If I tried to boot on B, it would just bootloop back into recovery, change to A and it booted but no update was installed.

Similarly I tried the local update method, by removing all magisk modules. Install locally, do not reboot, install magisk, install magisk again, and then install magisk to opposite partition. Reboot, and it would just reboot into recovery. I'd end up having to install TWRP via fastboot and again choosing to go with the A partition to get it to boot up.

Before bed last night I formatted all data in TWRP and reinstalled OOS beta 1. (I tried 2 but it wouldn't take then either, also redownloaded OOS beta 2 from a different source to make sure it wasn't corrupt)

I'm going to MSM it when I get home, and just give it a clean start.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
I can extract it so you can fastboot flash if you wanna try that way?
[OnePlus 6T  Guides, News, & Discussion] contesauce:
I appreciate it, but I'm still going to MSM. I just feel like it needs to be cleaned out. I briefly had the Essential phone and for about two months I was easily flashing things on A/B partitions without this much hassle. So I'm hoping that a clean slate will fix whatever is up with the other partition.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Got ya, yeah this phone has unusual bugs at times, they seem so random.
[OnePlus 6T  Guides, News, & Discussion] contesauce:
Agreed, I've been lurking in the threads since the beginning and there are a few things that are repeatable from user to user, but I'm seeing a few that just pop up randomly too. I still love my OP6t though, bugs and all.
[OnePlus 6T  Guides, News, & Discussion] BAmiri:
Is .11 considered safe to install yet?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
I'll install it now, give me a sec.

Edit: .11 is good to go for local updates.
[OnePlus 6T  Guides, News, & Discussion] BIGWORM:
Has anyone in here tried the latest 9.0.11 or beta 2? Flashed 9.0.10 and borked my TWRP and had to format data. =/
[OnePlus 6T  Guides, News, & Discussion] lendawg:
I'm on TMobile variant with no root and flashed 9.0.11 no problem.
[OnePlus 6T  Guides, News, & Discussion] contesauce:
So I'm doing the MSM now and going to flash back up to 9.0.10 for the time being. I don't use navigation bar (cuz nav gestures is awesome) and I don't use the OPO shelf. Anyone seeing any other benefit to the OOS beta 2 over 9.0.10?
[OnePlus 6T  Guides, News, & Discussion] djkinetic:
Someone in telgram..just flashed pixel experience from the op 6 to their tmo 6t and it booted we're testing cellular function now.

Edit: Cellular works.
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
Same here. I'd even just like to flash to just slot b. Only issue like you said, losing fastboot.

Do you know if it's still stored in the bootloader (abl) partition? I'm not sure if the system will attempt another slot if it fails on one slot or not.
[OnePlus 6T  Guides, News, & Discussion] djkinetic:
I believe it's still in abl looking in the partitions list it doesn't make sense to store it in a random named partition.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
T-Mobile 9.0 Full ROM should appear in the fastboot rom thread shortly, so you can follow the same steps to convert back to 9.0 if you need to restore back to stock for whatever reason and since it contains all the same files, with a working recovery we might be able to fully recover as a whole.
[OnePlus 6T  Guides, News, & Discussion] lemonspeakers:
Damn! reading through this entire 11 page thread makes me nervous after seeing that Justin guy already F up his device. Is this the First time he's done this?

I mean, I'm not new to flashing and unlocking bootloader at all. Done it to all one plus devices (aside from the OPX) but damn I'm scared. Lol.

The new A/B partition thing is confusing to me even after coming from the Essential phone. Can someone explain that to me later?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Partition slots are used for updating to make the process simpler, by flashing updates to the inactive slot, which also gives you the option to revert back to the previous OS version by changing back to the previously active slot.

In the case of Justin, he didn't have all the files in the same folder as needed, so when running the script, it flashed nothing, basically writing nothing to the partitions, hopefully we can recover his device, I thought I was clear in my instructions of file placement, I clarified this again after the accident with his device. Like modding any device, there are risks involved, hopefully we can recover his device with a full re-flash.

In the case of this full ROM flash though, both slots are flashed, so active slot doesn't really matter.

Hopefully things are clear enough now to avoid future accidents. And uh not sure how accurate I am, but that's my basic understanding of the slot system.

I'm so used to adb that I've forgotten how to get in manually
[OnePlus 6T  Guides, News, & Discussion] free4flight:
ok, bootloader unlocked, now want to flash the 9.0.5. I have all files unzipped, including internal zip files images.zip, etc...all in same adb folder, it says next to run the bat file called flash-all-partitions.bat ... so what is the command to do so? I tried flashboot flash-all-partitions.bat,didn't work, what is the proper command? Sorry haven't used adb til yesterday in a couple years. TIA
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
This button combo is new to me, last combo I remembered was vol down and power for fastboot...
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Its an executable file, you run it by double clicking it.

All files in the same folder, similar to my screenshot right?
[OnePlus 6T  Guides, News, & Discussion] free4flight:
yes, they are all there... so just double click on it and it will flash, I don't have to type a command in the power shell?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Nope, script is going to do all the work. Just have your phone in fastboot, double click, sit back and relax until it finishes.
[OnePlus 6T  Guides, News, & Discussion] ozzmanj1:
So would I be good to flash 9.0.5? And if something did go wrong, with the new Tmo base that being uploaded would I be able to revert to that should something go wrong with the 9.0.5? Or would you recommend I wait for full twrp w/ nandroid backup before proceeding?
[OnePlus 6T  Guides, News, & Discussion] free4flight:
Ok, running now, but am getting "invalid sparce file at header magic" ... normal?

done, went to press any key to continue, hit power key, went to crashdump mode... so now? Doesn't want to reboot, tried, but went back to crashdump screen... what to do?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Depends on how confident you are diving into it, if you're not comfortable or okay with the risk that something might go wrong, I'd say wait.

As of today, I have flashed 9.0.5 more times than I can count :eek:, I've literally done exactly what I said in the beginning of the thread to do and I've been fine running 9.0.5, the T-Mobile I flashed over that and went back the complete stock form the device came in, with the bootloader still unlocked of course. Since this is a full rom and we have the full rom files for the tmo version, both rom versions will flash to the same partitions currently, the only difference a fully working TWRP would make, in my opinion, is allowing us to flash criticals, in regards to recovery in the case of a total screw up? I don't think anything can really save us but the mtm tool, which we don't really have yet, sadly...
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
invalid sparce is normal, there's no way you flashed the full rom that quickly...
[OnePlus 6T  Guides, News, & Discussion] Addiso:
Even thought it gives you the invalid space file at header magic, you just have to wait and be patient. That's what it says in the fastboot rom thread at the bottom.
[OnePlus 6T  Guides, News, & Discussion] justibasa:
That's why I wanted to make sure and see. Am I going to be able to get in from the screen that is currently on the phone? Just power off and do the bottom combo right?
[OnePlus 6T  Guides, News, & Discussion] ozzmanj1:
Gotcha, well as long as I know I can revert back to Tmo in the event of an emergency, I am okay with that. I'm no stranger to flashing roms on my phones, been doing that since 2010. But just like to make sure I can always have a means to revert back/restore to a fresh rom. Thank you for your help, and you replies, thank you.
[OnePlus 6T  Guides, News, & Discussion] TKruzze:
Just make certain you're using the latest update from [MENTION=4712355]mauronofrio[/MENTION] and you'll be fine.
[OnePlus 6T  Guides, News, & Discussion] BIGWORM:
I'm wanting to retain root and have a workable TWRP, though.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
If you're rooted/modded, you need to reflash root/twrp in order to boot after flashing updates, if you don't you'll have to data wipe.
[OnePlus 6T  Guides, News, & Discussion] BIGWORM:
Did that. For some reason my TWRP could not decrypt internal storage. I was using version 11,which I believe they issue was fixed with v12/official. Still scared of having to format data again, though. =/
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
It was fixed in the newer version, you could switch slots back to the old OS, root should've fixed your issue though, worked for me...

Just confirming local upgrade from 9.0.10 to 9.0.11 works on a converted TMobile locked bootloader
[OnePlus 6T  Guides, News, & Discussion] tengtengvn:
I use the lastest TWRP.. Upgraded to 9.0.11 without issue.
[OnePlus 6T  Guides, News, & Discussion] :
If u flash an ota, it flashed a kernel. Boot.img=kernel. A boot isnt rooted yet when u flash the ota. And isnt patched with twrp. If anything, after flashing an ota, after u boot, boot back to bootloader, switch to opposite slot that still has twrp, flash twrp and magisk again. Or if u lost it entirely just boot twrp and repeat

Sorry didnt mean to quote you, just commenting.

Yes local upgrade works fine starting 9.0.7 and up. And from McLaren as well, for any uninitiated
[OnePlus 6T  Guides, News, & Discussion] hzhangonline:
Hi. I am on T-mobile version. Flash from 9.0.7, local upgrade 9.0.7, local upgrade 9.0.10 without issue. When local upgrading 9.0.11, it always give local upgrade failed message. Progress bar is at different locations, ~5%, ~50%. Any idea or steps need to pay attention?

I have locked bootloader.
[OnePlus 6T  Guides, News, & Discussion] strictlyphat:
No u seem to done it right. Maybe u have a bad download of the update file. Try to download another
[OnePlus 6T  Guides, News, & Discussion] hzhangonline:
Yeah. I did try different downloads, and same behavior. Only difference is that I use Ubuntu instead of windows to download and copy files. That shouldn't make any difference...

Solved: found a filename called INSTALLATIONNEW in the root folder. After manually removing it, installation succeed.
[OnePlus 6T  Guides, News, & Discussion] bigmikey307:
So do I always have to reflash TWRP after doing a Local Upgrade?
[OnePlus 6T  Guides, News, & Discussion] contesauce:
Yeah, you'll have to fastboot into twrp then flash twrp while you are in and don't forget to flash magisk.

So [MENTION=4204048]Dark Nightmare[/MENTION], after I did an MSM on my phone. I flashed 9.0.7, did a local to 9.0.10, twrp latest, then did beta 02 today, thought I'd push my luck a little and tried elemental x kernel on beta 02. For those curious, it works fine.
[OnePlus 6T  Guides, News, & Discussion] pm_mazur:
Hey to those who successfully flashed their T-mobile device, are OP updates rolling out just fine? Any issues with the device? Dual sim works fine, or single sim only?
[OnePlus 6T  Guides, News, & Discussion] phillymade:
No issues at all for me. When a new update comes out I just flash in TWRP to retain root. Dual SIM works, however, you will have the same IMEI for both slots.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Not OTA updates, manual local upgrade or upgrade via twrp.
[OnePlus 6T  Guides, News, & Discussion] _nkay_:
Hi, I'm trying to flash 9.0.7. This is the file to be downloaded right? -

9.0.7-OnePlus6TOxygen_34_OTA_013_all_1811270327_fbabbb-FASTBOOT.zip

I would like to relock the bootloader as well.. I'll go through the thread and find how to do that. Thanks!
[OnePlus 6T  Guides, News, & Discussion] guywong:
Correct. That's the fastboot file to flash right after unlocking the bootloader. You need to extract the zip file into a folder and then unzip the image.zip and Others_flashall.zip files and put those images inside the same folder without any subdir, using flash-all-partitions-fastboot.bat file.

After flashing the 9.0.7 ROM you can relock the bootloader and use local upgrade to flash a the most current ROM. The 9.0.11 ROM is OnePlus6TOxygen_34_OTA_018_all_1812260723_29c01e732b714cfa.zip.

If in doubt, reread the [MENTION=4204048]Dark Nightmare[/MENTION]'s OP. Good luck.

Steps to relock the bootloader:

1) Reboot phone back to Fastboot

2) fastboot oem lock

3) Boot into OS, disable "Enable OEM unlocking"

4) Factory reset again for good measure

Thank You OP and everyone who has contributed to this thread. Unlocking the boot loader was easy. My first ever OnePlus device. I have the T-Mobile version running 9.0.11 with no problem. I owned every HTC flagship before this.

It is possible to relock after loading the international rom. I'm on 9.0.10 and have it relocked.

Not while rooted....
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
From what I was reading, OP back on the 5t didn't do the certs for l1, so most likely they probably never got the 6t certified as well, therefore this device being capable of full hd streaming is a joke...

Well ain't that some crap..

[OnePlus 6T  Guides, News, & Discussion] _nkay_:
I flashed 9.0.6 a month and half ago. Cert was downgraded to L3. Later I came back to TMO version using the MSM tool and the cert got upgraded to L1.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
I'm relocked with l3, gonna msm and see what happens.

Edit: still l3, probably wiped something when fiddling with the msmdownload tool, something that can't be restored with a basic firmware restore, lol.
[OnePlus 6T  Guides, News, & Discussion] fogame:
Agreed. Lol that's why I run stock.

Edit: I'm TMO and relocked with L1
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Yeah I just msm download back to stock and went back to full global rom with a locked bootloader and still on l3, I believe when we messed with the system and wiped it while testing smt mode, we wiped whereever the drm keys were, I have all my partitions saved somewhere, I'll manually flash everything back later.

Restored partitions, even disabled oem unlock since, still l3, not sure which partition its on, so can't restore what I don't have, I think I restored everything.

A day or so later now and I'm noticing I'm missing notification sounds and or vibrations unless my screen is on or very recently put down.

So you never had to unlock your bootloader to go from tmobile variant OS to the global OOS? I'm not interested in rooting or custom roms, just want the stock OS to unlock the second sim slot for travel.
[OnePlus 6T  Guides, News, & Discussion] :
U have to.
[OnePlus 6T  Guides, News, & Discussion] I<3cats:
My concern is the DRM issue of not being able to revert it back to L1. Do you know of a way to avoid that or reinstate it if it does have issues?
[OnePlus 6T  Guides, News, & Discussion] joemossjr:
You cannot lock your bootloader while rooted. You will have to run the msm tool to recover if you do

[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Do the local upgrade to the latest version, you can do it even if you're already on that version, when you're done, then lock the bootloader.
