You used a ROM that upgraded your keys, you need to format storage if you want to use PIN or similar with OOS again.

Now back on topic.

Oreo builds are unified, also good to go on 5T Oreo stuff :good:

Because of latest TWRP and Oreo changes, you'll need to use TWRP 3.2+ or my unified TWRP 3.2.3-x blu_spark v8.83 (recommended).

Any other versions may not have full support for the kernel and the installer.

This is for OOS treble only (OOS 5.1.5+OB16/14)

Meaning, if using anything besides stock and stable OOS don't bother posting about it.

I am only interested on debugging stuff in stock and stable OOS (with logs and reproducible steps to replicate the issue).

blu_spark extras v9.85

All right crew!

Here's an updated TWRP with all the blu_spark goodies inside and fully synced with TWRP Android-9.0 branch (including more recent upstream than official TWRP) and some specific device fixes.

Fully synced with TWRP 3.2.3+, name changing to reflect base 9.version, full compatible with current (and probably upcoming) Pie, Oreo and Nougat stuff.

TWRP blu_spark edition is not only universal but also unified, works for both OP5/5T.

Delete your twrp settings or else issues may arise if coming from other version besides blu_spark.

This build is treble ready, allowing /vendor partition operations. If you don't use treble enabled ROMs, ignore any vendor errors that may appear, TWRP will work just fine.

twrp-3.2.3-x_blu_spark_v9.85_treble-op5_op5t.img

So apparently i can't decrypt my data upon flashing the latest recovery. As expected i'm prompted to enter a password to decrypt but the thing is, i don't even have a pin lock on my lockscreen. The issue seems to get resolved upon removing my pattern lock.

i'm actually experiencing this from a few versions back though. Anyone with a similar issue?

Device: op5t oos ob15, stock unrooted
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] tcat007:
No problem here, but I decrypted a couple versions ago. I always remove pattern lock before messing with anything in recovery.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Chaplan:
I can decrypt both with PIN and Pattern lock on the latest and previous TWRP builds.

I'm on keymaster 1 and OOS.

You on the other hand must be on something else entirely, apparently at least. :angel:

Going custom will **** up the possibility to decrypt in TWRP when you go back to OOS, this has been discussed plenty.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] ALPHAWolf96:
Just to be more clear, I haven't decrypted my device ever as I've always been on oos since the beginning cause I use face unlock extensively. So that pretty much rules out that point.

Also, I just clean flashed the latest ob15 again to recheck and set a pattern lock and I was again prompted with a password lock on twrp so I guess there is really an issue which needs to be looked. But nvm, I usually do the twrp stuff after removing all the locks and patterns unlike this time.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Chaplan:
Going unencrypted is beyond the scope of my answer, and rather unsecure if you ask me, never used it on this device, never will.

You can flash a custom ROM encrypted and use it without an issue as long as the ROM supports encryption.

The thing is custom ROMs updated keymaster and OnePlus never did, so going back works wonders as long as you use the workaround you already are using.

Formating /data will get it up and running flawlessly if you must. (Backup, backup, backup...)

If your device only ran OOS as you say.... this ? will work nonetheless.

PS: Clearing the .twrps file under TWRP folder would be a great idea also if you have used other TWRP flavours. Give that a go first if you must.

Good luck.

I can't decrypt inside twrp since I flashed custom Rom and went back to OOS Beta.

I tried all 3 TWRP latest versions, official, codeworks, and BluSParke (currently on it).

Only stock OOS Recovery is able to decrypt, which doesn't help me much since I need root.

Any ideas how to fix this (Tried deleting TWRP settings) ?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] The_Overthinker:
It's a known issue. For twrp to be able to decrypt, you'll have to format phone when returning from a custom rom.

OR you could remove your screen lock everytime you access twrp. That way you don't need to decrypt and you can access your files.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] rijads:
I have been doing the second thing, what exactly do I have to the to "format phone" ?

Do factory reset on OOS, or inside twrp some option ?

Can I save backup on phone without having to move everything to pc ?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] The_Overthinker:
Main menu -> Wipe -> Format (on the right side). It'll ask for confirmation (type yes).

WARNING - This will wipe EVERYTHING. Including internal storage, so make sure you have a backup of all your stuff.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Kaskouy:
Be warned that if you don't flash a decrypted ROM along with dm-verity this will not solve the TWRP decryption issue...

If you plan to use stock OOS without disabling force encryption you will still encounter the same issue even after formatting
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] rijads:
Yeh, then it won't help me for now as I use Official beta with custom kernel, twrp and magisk. Hopefully OP fixes this in Pie.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] The_Overthinker:
If you plan on using plain OOS stable or beta after using a custom rom, just format your phone and flash the rom. Then flash your custom recovery. This will solve the encryption issue, you don't have to flash no verity or anything.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Macke93:

Well that's weird, that's exactly what I did, twice, and it did not fix the encryption issue. I'm on latest beta 16.

Edit: with fingerprint and pin enabled of course, if you disable them everything s going fine, but the point is to be able to access twrp while keeping security settings on
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] The_Overthinker:
You sure you FORMATTED the phone and not just factory reset? There's a difference
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Kaskouy:
Yep, formated, ext4, erasing all content on the phone. I've been flashing my phones since Galaxy S first of the name, I have a slight idea of the difference :)

Anyway, maybe a OOS beta 16 specificity ?
