You been under a rock for 3 months? [emoji23] OP doesn't own the code to the fp sensor, they only buy licenses to use the tech. Its up to the manufacturer if they want to allow OP to release the code. Which it doesn't look like they are gonna do. OP is fighting it, but I doubt it will happen. So, the ball has been left in the custom rom devs court to figure out.

I need ur help pls.. how to update to the latest oos version with out loosing root? I tried the magisk "uninstall-restore images". But it says "STOCK BACKUP DOES NOT EXIST" Can you help me pls.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] EBeatFLA:
I did it pretty simply, followed the directions OnePlus gives, right in the same thread you download the ROM.

Make sure you have the OOS ROM zip, TWRP 28 installer zip, and your Magisk zip.

To avoid issues, if you use Substratum, uninstall your overlays, I was not able to restore them after without causing bootloop, so yes uninstall.

To avoid issues with Magisk, disable all of your modules and reboot. Keep in mind some modules will cause bootloop if restored, so try one at a time, and use the Magisk uninmod zip in TWRP to remove if there is a problem.

Anyways, to update, I used TWRP 28. Flash the ROM (it takes a long time so be patient), flash the TWRP installer, reboot to recovery back into TWRP, then flash Magisk and boot. All done.

So I have the encryption problem from oss mismatch. I think anyways. I think a local update only updated one slot or something. I did that before I rooted the phone. How do I get both slots the same again so I can decrypt slot A. Will 9.0.12 zip do it? Or do I just wait for my USB c SD card reader? I hope I don't have to use msmtool...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] SourPower:
Hello, I am in a bit of a dilemma. I'm still on 3.2.3-8 and I'm having an issue with deception when booting to TWRP. So do I just need to fast boot the latest TWRP img?

I have magisk now on oos 9.10, wanting to update to 9.12. Thank you
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] wickedesires:
For anyone who is still experiencing the error 255 when trying to restore a backup I found a solution that worked in my case. Before installing the .012 update I disabled all my Magisk mods and substratum themes then flashed the update. I forgot about a fingerprint mod I'd installed and there wasn't any issues at first. Later I saw the author made a new update that worked differently. In short after updating I restored the stock file which caused a bootloop. I tried restoring my .011 backup and the first attempt after a wipe always works for me, but won't boot. So I

1- wiped again and installed the full .012

2- flashed recovery then rebooted to recovery

3- flashed Magisk

*Everything below was done in one session without rebooting recovery*

4- restored .011 backup

5- flashed .012 update again

6- flashed twrp and Magisk

7- wiped dalvik and reboot

After this it booted up updated and with my original configuration intact. I could restore fine until the first reboot then the file system would get all screwy (and thus all of this was done through otg and an SD card) All the steps above may not be necessary but it's what worked for me. I keep at least one backup as well as all my music, the latest Magisk APKs I'm using, and the latest Twrp and Magisk installers on this SD card just in case. I would recommend you do to if possible. After a clean flash of the full stock room I was always able to complete a restore. After restoring then rebooting Twrp or the system was where my problems were introduced. I know this is kinda long and drawn out and so was the process, but it kept me from having to stay fresh again. I hope it helps.

[MENTION=4712355]mauronofrio[/MENTION] I tried your test build -29 with OOS 9.0.12. It asks for password. I enter pin code and it boots back to asking password.

Then I can click cancel and my device is decrypted.

With -28 stable and OOS 9.0.12 it asks for password and decrypts correctly.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] blackphanter:
Just click the cancel button after it boot into twrp and gave your password earlier. It decrypt but the boot back screen a kind of bug.

Edit: sorry i didn't read the whole message. I'm on 9.0.11. and the hint above is working.

A few of them have either incomplete instructions or the wrong instructions all together.

Thank you for the instructions as well as why it has to be done this way.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
Yeah i had some lame try telling me this would brick users phones and I was such a moron etc.. This IS the way.. Do not reboot recovery. Nothing else matters so much as long as u skip that crap. I factory reset both slots, flash ROM, twrp zip, gapps, magisk, and my migrate backup zip. Bam. Perfect.

[MENTION=4712355]mauronofrio[/MENTION] - thank you for your work!

Moved to the 6T from a OnePlus 5, lot of change to A/B devices.

Flashed the -29 test right away, had the decrypt password bug that you are aware about.

Tried the backup and had the 255 error. Checked for parallel apps, none existed and no other user either.

Flashed the -28 version and both bugs are gone. I was able to complete a full backup without issue.

Just for information. Thanks again.

Little help here. I searched the thread but could not find any info so...

When i boot to twrp i am asked for pin or pattern, after giving it i am able to successfully view all my files, i noticed i was in slot a but after that when i try to boot back to twrp i.e to slot b twrp is not asking any pin or pattern and all my files are random letters and numbers so i guess slot b is encrypted. What i need to do to make it right ?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] blackphanter:
It's a good question. I've never tried to make back up without vendor image and also never tried to restore with vendor image.

mauronofrio earlier adviced to make image backup instead of system, vendor etc. Later I've read in this thread someone try to restore vendor image, system etc and got a bootloop. The solution was restore without vendor image. So when i had to restore the first time i just restore the backup without vendor image.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] MisledMew:
Hi guys, need help. I have done this earlier successfully, but this time my phone is stuck in a dirty bootloop.

I installed the new system update and then proceeded to install twrp.

Booted using the img file, did adb sideload twrp-fajita-3.2.3-11 installer -> Reboot system -> Reboot to recovery -> sideload magisk.

Phone won't boot up from here on. I'm stuck on the one plus splash screen, it reboots to twrp again after a while. What's going on?

Edit: Also, earlier when I booted into recovery twrp used to ask for password and stuff (for decryption I guess). I don't see this now.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ZeroKool76:
To clarify. I have made a backup of all 4 partitions. And as long as you wipe all 4, you can restore all 4. I have done it half a dozen times

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ZeroKool76:

---------- Post added at 12:54 PM ---------- Previous post was at 12:33 PM ----------

Just tested it again, on custom. Worked fine. Backed up all 4, wiped all 4, restored all 4 and here I am again [emoji869][emoji41] Probably not as important on OOS. But since custom roms use different vendors. That's probably where people are going wrong. Restoring a different vendor to a different rom. Just a guess
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] nostradomis:
Out of curiosity, I skipped the OOS install step to install Havoc. instead, I installed only the vendor.img from 9.11 followed by Havoc 2.16 and TWRP 28. rebooted recovery installed gapps and magisk. rebooted and everything works.

also tried nine 9.12 vendor. img

https://my.hidrive.com/share/z7pzewju-r#$/

and everything is working fine.

this could make a clean install much easier since all you really need is the vendor image to get the right firmware.

please tell me if this is not right.

In TWRP code how do 'wipe', 'backup' and A/B tie together. In other words, does a backup/wipe up system only backup/wipe the current slot?

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] H4X0R46:
I've had some weird bootloops here when messing with TWRP, and this could be why! That's weird, so restoring the vendor partition just shouldn't really be done then?

So couldn't we rewrite twrp to pull slot a and b data separate and restore each to proper slot, bc restore data has not ever worked for me so far. Just wondering if their is some solution I am missing
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ZeroKool76:
28 is no where near done, nor are any devices that use AB. Sure, you could probably code it to work that way. Unfortunately, I don't know how, so I am content with what is available and just adapt your flashing and backing up to make up for what TWRP lacks. The whole Idea behind AB is retarded, redundant, and offers more cons than pros IMO. Cant say that I have heard of one person praising AB. Wonder why that is...CUZ IT SUCKS
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TKruzze:
I couldn't disagree more. Setting aside the measly few of us who actually unlock our bootloader, the A/B system has huge benefits for most users. Just a few are:

1) Nearly instantaneous ROM updates. I remember having to set aside an hour of my day to apply an update while my phone was completely out of commission. And then, when it did finally boot up, it took another several minutes before it was usable. With the ever growing complexity of Android, this would have even become more pronounced. However, the AB system allows the update to be applied to the inactive partition, almost invisibly in the background, and then a simple reboot of the phone and I'm back in business with almost no downtime. I had friends refusing to apply updates to their phones because they found the old system to be too cumbersome.

2) Since the update is only being applied to the inactive partition (the current running partition is untouched), this is a huge benefit in case something does go wrong because the phone will automatically switch back to the untouched partition if something does go wrong during the reboot update process.

Those are just the main reasons. There are other benefits as well. The biggest problem I see is that most users don't understand how it works and rather than learn the ins and outs, they disparage it. After spending some time reading and learning the entire system, I can now see how it is a beneficial and natural progression of the operating system. Is it more complicated for development? Yes, for sure, but once you learn the system, it'll become as natural as the old one.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ZeroKool76:
I stopped reading after the first line. Measly few of us that unlock? You realize you're saying that in a CUSTOM RECOVERY THREAD. Looks like a lot more than a "measly few" unlock. But, whatever. And I am fully aware of how AB works. Still blows. Maybe not for locked users. But you don't see me saying this in their thread, do you? Its an unnecessary hassle, made to give OEM's a failsafe. Again, I guess if you wanna buy into that, locked, sure. I could get behind AB, if you had a dedicated recovery partition. The fact that they don't, just tells me that they don't want us fukn with our sheit. So, in closing, AB on a locked device, sure. Greatest thing since pb and j. Again, if you buy into it. On an unlocked device, its the worst thing ever, without a dedicated recovery partition.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] MisledMew:
Thanks, that was helpful. I would still like to know what went wrong in my case
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TKruzze:
First thing I'd do is make certain you're using a recent version of TWRP. (-28 is probably best).

Then, instead of sideloading TWRP and Magisk (as shown in your steps), simply flash them using TWRP.

I'd recommend following the steps as shown in the OP here:

I did a factory reset (lost some irrelevant data, doesn't matter) and tried all over again with updated tools (magisk and twrp). It looks good till this point.

Further ahead I run into frequent bootloops when installing magisk modules. OS got corrupted. I did a dirty flash and installed latest OOS and I am yet to reinstall modules again.

I believe I'll run into bootloops again. I guess clean wipe is a better option in that case?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] MisledMew:
