@Lossyx , oos10, 10.0.16 HD65BA (eu)
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] ChrisFeiveel:
This twrp is for oos 11

Oos 10 and oos 11 have a different encryption
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Neeosx:
it says data successfully decrypted on the screenshot. Am I missing something?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] ChrisFeiveel:
data backup still has a 255 error on 7t (oos 11 beta 5)

and mtp doesn't seem to work.

may one ask how they got the decryption fixed?

Is this recovery good for custom roms with android 11?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] wugga3:
Don't know but I'd guess

Oh heck yeah it would rule cause if it works on stock it would rock on custom

but I don't know and really just guessing cause may be I'm overly hopeful to see TWRP possibly back cause I misssssss it so very much from my Samsung galaxys S7 days with Superman ROM (ultimate ROM Ive ever used thanks)

But someone more knowledgable will say for sure if/when the time arrives ..... Until then I'm all in on the page refresh/reload since it's my new home page now !!!!!

Might even keep this device another couple of years of this works out cause I about gave up.... Any way good luck and huge thanks to everyone's efforts and contribution here

Remove all screen locks before trying to backup data
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] HueyT:
No, oos11 only. Use 3.5.10 twrp on github for many custom a11 roms (though P.E. still uses fbev1 and needs Chinese twrp 3.4.x) as they use fbev2 encryption.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Lossyx:
PE uses FBEv2.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] parag0n1986:
@Lossyx How can you tell if a ROM uses FBEv1 or v2 or sdcardfs?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] HueyT:
You have to look at the codes. Weird but Chinese twrp (fbev1) decrypted latest P.E. while twrp 3.5.10 would not (fbev2). May be custom kernel messed up fbev2 encryption
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Lossyx:
Fbev2 build should decrypt fine in PE. I used PE as testing when I made the recovery.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] parag0n1986:
The source code? If so, where in the code is it usually located?

Edit: @Lossyx nevermind, I read the deprecation thing better. fbev2 for sure. Thanks. Can both sdcardfs and fbev2 be used at the same time?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] HueyT:
Your twrp indeed decrypts oos11 fine but I can't get it to backup data using same twrp to USB OTG or internal SD--all other partitions backup fine. I can browse and access, alter, copy, delete internal sd and data fine with twrp file manager. Just can't backup. See twrp logs (backup attempts at end of logs).

Yes I understood the situation and that it's common on android 10 native device. I hope that in next weeks a working twrp can be available for all native android 10 devices. In any case I was able to root the device by flashing patched boot image and installing magisk manager. It works also with standard magisk manager apk, Canary is not mandatory. Also smali patcher works.

[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Krazy_Calvin:
Isn't this pretty vital information that should be updated in the OP? It gives no obvious impression that this isn't ready for public consumption. it looks like the standard warning about installing at your own risk.

[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Aswin08:

But fyi its kinda mentioned in technical terms i guess. TWRP boots. Nothing much useful works as of now.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Grin59:
Once twrp gets working is there a dev willing to build lineage?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Krazy_Calvin:
AS a layman i feel it should say "for developer testing only, not currently able to flash" Word it however you need to... but if I saw that I would immediately stop in my tracks since I am not a developer and the only reason I would want this is to flash something.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] kessaras:
Nope. Not me.

I'm willing to build, but not lineage.

Also if TWRP is not ready until I'm ready to go to a custom ROM and abandon oxygen , I'll do that too.

All OnePlus devices have amazing support. Even if I don't do anything in a few days there will be hundreds of Devs for this device. I'm now enjoying Oxygen. I haven't had a OnePlus since 3T.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] grandpajiver:
I concur.

Patiently waiting for twrp, then Havoc. I loved it on my op3t.

Right now I'm just missing 2 things, v4a and would wish OOS would stop killing stuff. I've disabled battery optimization & adaptive battery. Otherwise I'm fine and can wait. I just get nervous with some magisk mods & one substratum theme that totally bootlooped me so I had to wipe. Mind you, if I would've adb shelled, ran su, and granted permission I could've probably gotten out of that mess.

Sorry, a bit OT. Loving this phone, and everyone will just have to wait and be super careful.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Grin59:
Does anyone know a dev willing to work on twrp? I'm seriously considering paying someone to make it compatible, one of the twrp devs, from what I read on the twrp website, is really busy irl so we're going to be waiting a fat minute for anything to happen. I don't have time to learn or a computer to use to build, but I could pay or help pay if a bunch of people got together for a bounty so a dev can work on twrp.

Loved your work on the LG G4 before mine died from the common hardware issue. Good to see you here.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] mauronofrio:
The real problem is that the devs who have the 7 pro won't go to buy the 7t pro, so it would take a dev who has the device to work on it and right now I don't know one. In addition to this with Android 10 there have been a sea of ​​new features that have led the twrp to be unusable on devices coming out with Android 10, someone should work on this side before having a working twrp. For the previous oneplus devices I worked on the front line to bring working twrp, but this time will take longer.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] kessaras:
Just a "lol".

I'm enjoying Oxygen OS. I'll work at my phone when I feel like it.

I said that I will do it and it doesn't matter how many Devs there are and keep your money. It's opensource. We don't pay for opensource.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] mauronofrio:
Open source does not mean free, it means that everyone can do what they want from the sources (always respecting the various licenses / copyrights). If someone wants to pay for a dev to do something opensource is free to do so, although it is a bad thing seen by many devs. That being said, this my twrp is a base for something better that will come in the coming months, I think that before January there will not be a fully functional twrp. I hope that oneplus sends the devices to the various developers in its developer program, maybe this could speed up the times.

Install latest Magisk Manager Canary, patch the latest stock boot.img (with keep force encrypt and keep verity), then flash from fastboot. Working great here.

You can dump the latest boot.img using fastboot boot TWRP, then `adb shell dd if=/dev/block/bootdevice/by-name/boot of=/tmp/boot.img` and `adb pull /tmp/boot.img` to your PC.

https://xdaforums.com/oneplus-7/help/android-10-root-twrp-t3964115/page3#post81061935

Since stock kernel seems to be our problem on 7t maybe twrp would flash on blue spark kernel ?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Lossyx:
EDIT:

The guide you got directed to instructs you to flash a zip in TWRP, but TWRp is not functional for our device and cant flash zips(or even decrypt). The problem is not about keeping magisk and twrp together or the kernel, it's about the major changes in devices launched with Android 10 that breaks TWRP.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] osm0sis:
Plus interestingly this device adds back a dedicated (A/B!) recovery partition which is not part of the AOSP spec for 2SI SAR (2 stage init system-as-root) devices, where Google still suggests using boot-as-recovery when it's an A/B device.

Once the Android 10 bring-up for TWRP is done the upside of this is not having to mess around with flashing TWRP into the boot partition anymore, though we might still want to use zips to flash to both (A/B) recovery partitions at once.

No. You still aren't understanding. Do what I wrote. TWRP automatically symlinks to the current slot. The path I gave you works perfectly from TWRP which is why I said to use it.
