Ah, that confused me, too. If you have root you can flash the TWRP installer with Magisk Manager. If not, just fastboot flash the TWRP Q file. OOS A10 doesn't allow fastboot boot at the moment.

You won't be able to use Titanium in A10. I don't know if there's currently a workaround. Android 10 does r/w system. Maybe try Migrate instead, from Pie. I have no idea if it works on A10 either, though. Just spitballing

EDIT: Does anybody know if you can restore user apps with Titanium on A10? I'm tired, but that shouldn't have anything to do with system, right?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Rickydwi:
where do we flash the oldkeymaster.zip ? im currently rooted with magisk 20 no twrp though cant seems to install it as well even after formatting data
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] techlogik:
Don't try any of the methods..nobody has TWRP working properly decrytping....if so, it was pure luck they didn't brick the phone and have to MSM back to stable and start over.

Root is easy, even TWRP, but getting the proper decryption is the issue. Just chill, there is no need for TWRP really, root is good enough with Magisk and that works fine right before the update using the typical uninstall, restore images, do the update, before reboot, install/install to Inactive slot...reboot. You will have root with Q...otherwise...no stock recovery anymore when rooting or TWRP with root.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Causical:
I don't know if I'd exactly be encouraging this at the moment either though. Last thing you want is for a bunch of people to think okay I'll just go be on beta A10 (that I may or may not be satisfied with stability wise) then want to downgrade and realise the only ways they have to do so is to use either the MSM tool or the Rollback.zip (both of which I believe you lose your data).

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] PokemonTotalWar:
Mauro's method is perfectly fine, and, at the end of the day, Overdrive's method does the same thing as his. There's no luck involved in flashing OldKeymaster before rebooting after flashing your ROM :cyclops:

That's not to say it's a great solution. I'm sure it causes some security concerns
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
Since you MSM'd to stock, I'd recommend trying to Local Update again. Just make sure The MD5 of the file is same as provided in the OP

Thanks bud, will try.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Timmmmaaahh!:
In plain language our 'expert' advice is as follows: if you're on a T-Mobile branded 6T (converted or not), DO NOT UPDATE for now. Unless you're knowledgeable enough to sort out any issues or you accept the consequences (a world of digital pain with the off chance it actually works fine). Did I get that right? I'm open to constructive feedback ^_^

Yea, what ever you did to get TWRP running i must have done something wrong here...

This is how i did it (Not working):

Installed OB1 (10) Not rebooting.

Installed magisk trough Inactive slot.

Reboot

Checking Magisk. (Fine)

Flash TWRP 3.3.1-20 installer trough Magisk Modules

Flash Magisk Direct install.

Reboot.

Reboot to recovery. (Ended up in fastboot mode)

Reboot.

Flash TWRP 3.3.1-8 trough Magisk Modules

Flash Magisk Direct install

Reboot.

Check Magisk. (Fine)

Reboot to recovery. (Ends up in fastboot mode)

Followed this every step, not having TWRP at all, when i reboot to recovery i come to fastboot mode, i tried rebooting again, no TWRP straight to fastboot.

Not to sure what i did wrong, but i got all night messing up my device to get TWRP working xD

Do you have any other ideas to get TWRP working? Hit me up!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mattish.91:
20.0 (20000)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ecera:
What version of magisk and twrp are you using? I took similar steps and had twrp working, but magisk did not appear like with you. When I booted into twrp and flashed magisk....yeah magisk was there when I rebooted, but twrp was gone :confused:
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
Flash the magisk 19.4

And try the 3.3.1- 8 TWRP
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mattish.91:
Yea, not working xD

Im back at fastboot when rebooting to recovery. magisk however is still installed (19.4) and working ^^
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
Try to" Fastboot flash boot" the img

Dont install via magisk..

If it boots flash the installer flash magisk.. reboot
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mattish.91:
Well i flashed TWRP before trough magisk (Without flashing back Magisk and ended up in fastboot only) thats why i have decided to ALWAYS install Magisk after the TWRP flash, that way i get to keep magisk and boot.

---------- Post added at 12:17 AM ---------- Previous post was at 12:15 AM ----------

what img do you want me to flash? the TWRP img? that's not going to happen xD since TWRP doesn't boot that way, already tried that and messed up system as well xD

Tried this TWRP+Magisk img

Not working, it does boot normally but not TWRP.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ecera:
[MENTION=1083707]efex[/MENTION] got it working using your steps and using magisk 19.4 and twrp 3.3.1-20.

the key here is to at least get twrp to boot, which was just mentioned above. Use the 3.3.1-20 Q img that mauronofrio posted boot your phone into bootloader and in fastboot run the command "fastboot flash boot nameofrecovery.img". You'll then toggle your phone using the volume buttons to reboot recovery and from in there just follow the steps that were mentioned by [MENTION=1083707]efex[/MENTION] when he replied to my post. In my case I used magisk 19.4 and twrp installer 3.3.1-20 and I can confirm that twrp and magisk now stick.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mattish.91:
Well, damn! it does work! how ever storage is encrypted, but thats a small price to pay anyways, i got a OTG cable, plugged that sucker in with a USB-drive, and voala, i got all the flashing files i need :D everything flashes sucessfully no problems at all ^^ except encrypted internal storage xD
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
Nice

Which twrp.?

To decrypt you need to format & oldkeymaster flasher zip
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ecera:
I believe flashing the oldmasterkey.zip while flashing the rom fixes that. My internal storage is decrypted and I'm able to see all my files. Or if you did flash it you have to first "format data" (where you type yes) from the wipe tab in twrp.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mattish.91:
Flashed TWRP-3.3.1-20.img to boot

rebooted to twrp

full wipe

copy over TWRP-3.3.1-20-installer.zip

copy over OldKeymasterFlasher.zip

copy over Magisk-v20.0.zip

Flashed OldKeymasterFlasher.zip

Flashed TWRP-3.3.1-20-installer.zip

Flashed Magisk-v20.0.zip

reboot to system

Also, OTG is working just fine :D

Setting everything up right now, it did however feel a bit fishy flashing a recovery to boot partition xD

But it does however work if magisk gets installed afterwards, just like you mentioned. a huge thanks for your instructions and help along this crazy road xD

I did this twice just to get OldKeymasterFlasher installed correctly, and im still not sure if it's correctly installed tho, i will soon find out ^^

Decryption is working fine now aswell, i don't have to type a password tho ^^

Just like old times!

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] anthony10126:
I am having the same issue but worse.. I tried flashing the twrp in magisk aswell cuz I kept going to fastboot mode..bad thing is I didn't flash magisk when doing so. So now I have no twrp and lost magisk.. tried adb fastbooting the latest twrp image on my PC and I'm getting failed :unknown command.. any ideas what to do next guys??
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ecera:
In fastboot run the command "fastboot flash boot recoveryname.img" (I used the Q image) then using the volume buttons toggle to reboot to recovery and you'll be in recovery. From there I proceeded to format data under wipe in twrp flashed rom, oldkeymaster, twrp installer (3.3.1-20) and lastly magisk (19.4). I then made sure to switch slots in twrp under the reboot tab then rebooted to recovery and repeated the steps. On my first reboot magisk did not appear. So I rebooted to twrp and reflashed magisk and it was there.

Note: format data will wipe your internal storage, I used a otg usb adapter to flash the files. You can also transfer them from your PC while you're in twrp each time you flash. I would think you might have to reboot to recovery after performing the wipe to be able to transfer the files to your phone though.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] techlogik:
Some genius on another thread claims blu spark is working fine for TWRP and kernel...of course, that person registered recently and has like no post history...and the thread went down the toilet...ROFL afterwards. Whatever. Like a lot of people, who didn't want to lose their data, they probably went up to Beta 17, then got the OTA, or file, then went into the typical method listed above...and have no decryption in TWRP afterwards.

The other method might work, but it will require you to blast/wipe the phone and follow the specific order to get to that point, when you don't really even need TWRP IMHO...and with flashing issues of the newer phones, need to get used to that....ROFL. Whatever, I got root and only use it to modify my WAZE skins to custom colors...otherwise, I guess I really don't need root except to mess up my phone, test tweak etc..

Let us know how this all works out.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] anthony10126:
I really didn't want to wipe my data... Honestly should have just waited for a stable twrp... But is there any way I can revert back to pies latest beta so I can retain my data , previous twrp, and magisk??

YOU ARE THE MAN!!!... running android q with root... i guess ill have to wait for a stable twrp but i did not have to wipe the phone.. Thank you.. Another question... I usually like flashing the newest betas on both the a and b partition.. Now that we have no twrp, is there a way to flash this q beta onto my other partition without wiping?? or should i just leave it as is and wait for a stable twrp to do so ??
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Timmmmaaahh!:
I guess technically that's what another local upgrade would do but I'm not sure how OOS acts on installing the same package twice - never tried it. Will either just do it (in the other partition) or throw you a "you're already on this version" error. I wouldn't really meddle with our current situation as it all seems to be quite unstable for now.

Thank you for the response, but my question is a little different.

I am on T-Mobiles branded device, but I am not making any attempt at moving to Android 10 yet. I am just trying to install LineageOS 16 (which is Android 9). This is where I am seeing the error.

++Edit:

Just to update, I have been using the international variant of Oxygen OS for almost this entire year. I decided to move on back to LineageOS today, and it seems not many people have had any problems doing so. I have first flashed the correct 9.0.11 international build via Msm, then performed an OEM unlock, then loaded the latest TWRP available here, then sideloaded the latest LineageOS nightly (no stable builds on their site), gapps, root, etc. Then reboot... and it comes up with that dreaded error every time.

As far as I have been able to tell, there aren't many people who have run into the same error I have. They seem to be running LineageOS 16 just fine.

Hello everyone, I've read that some devices are not being able to decrypt unless you install oldkeymasterflasher.zip but in the first place I manage to update to Android 10 from 9.0.17 beta, I have a T-Mo OnePlus 6T converted to international which the update was already rooted, so all I had to do was to install Magisk Manager and then I installed TWRP zip (screenshot) without oldkeymasterflasher.zip and once I booted to TWRP for the first time I was able to decrypt as shown on screenshot, so I'm running Android 10 rooted and TWRP capable of decrypting, I just installed Omega kernel as well.

Yes it's possible for u coz u might have fastboot flashed the ROM and hence flashing only some of partitions with android 10 elements. So u already will have old keymaster and twrp will work fine. but for those who updated through internal update system will have all the partitions flashed and replaced with android 10 elements and that's where the problem arises and one has to go through the keymaster flashing process.

Because your TWRP cannot decrypt /data, and hence the "/sdcard/TWRP" folder isn't readable or writable by TWRP. This folder is the one that maintains the TWRP settings.
