Also I know that there is someone else who build Orangefox recovery a few days ago using FBEv1 for Oneplus 8 and 8 Pro.

As my unified Orangefox now is using FBEv2 since that is what is used on Oneplus 8t and 9r so te Unified Version is using that.

So you will only be able to decrypt data with my unified Orangefox Version when you use some unified ROM which is using FBEv2.

I will check with the one who build Orangefox with FBEv1 for Oneplus 8/8 Pro if he has published that already somewhere.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] tnchng:
Maybe the FBEv1, thank you very much. I'll test asap when you share it.

EDIT:

Whoops... just saw the top post... "Orangefox R12.1 can only be flashed to the recovery partition"... Will this affect Stock OOS12 to update in the future? or can I easily restore stock recovery?

****************

Hi! Does this work with OP8 OOS12 unlocked + rooted? can I do "fastboot boot recovery.img"? Not really worry about decrypt data, just want to get in to flash Magisk. OP has been very bad at releasing full ROM, can't extract boot.img for that purpose.

Like many (I think), I try official TWRP to "fastboot boot recovery.img" and the device got stuck... Anyway... I left the phone for few days..., it booted back in fine.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
No it will not affect stock OOS to Update.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
I'm using EvolutionX 7.3 (Android13) on a Oneplus8Pro. Do you know which version of the recovery do I have to download?

And also, which encryption does the rom use?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
No. I dont know. Check with your ROM Support group or just try to fastboot boot the orangefog.img file and see which Version works.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
I can boot all three version of the recovery, but it seems none of them can decrypt data. The Data partition dimension is 0mb.

Anyway, is the first time I use orange fox, and i don't know it very well....
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Just google it or ask in your device Telegramm group.

[OnePlus 8 / 8 Pro & 8T Cross Device Development] returnedinformation:
I've tried booting OrangeFox V29 and can't decrypt Data Partition on my phone which has LineageOS 21. Any help?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Are you using OP8/8Pro? Then I assume it is due to that LineageOS is using FBEv1 decryption for your device. My Orangefox Version can only decrypt data on FBEv2 ROMs.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] returnedinformation:
OP8

I see... too bad, I've already fully configured my LineageOS.. Is there any way I can know which FBE version it is beforehand, or at least find out by myself? Backing up data partition and being able to access file offline would be a really nice thing.

Edit: found in older posts that I'm suppose to figure that out with my custom rom support group. Sorry to make it your problem
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Kyanoxia:

A simple question.. As I'm new for this

I have oneplus 8 pro

Project elixir rom a14

Which link I download this recovery for my phone
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Check which envryption method your ROM is using.

If it is FBEv1 then my Orangefox Version will not work (it will boot anyway but data can not be encrypted then!).
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
As far as I know, the most of OP8P roms are FBEv1 encrypted.

saurabh_parab recovery is compatible with A14, but I'm haveing more and more problems since the last update is 09/11/2023.

Probably not but, is there a way to change the rom encryption?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
I dont think you can do that. You need to check with the ROM developer on that.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
You're right :(
[OnePlus 8 / 8 Pro & 8T Cross Device Development] 535iu:
Stock OOS 13.1 is ext4 or EROFS?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
I don't know, but you can check it with DevCheck from play store.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Yes I guess that is because your ROM is using FBEv1 and this Orangefox is using FBEv2 as decryption method.

Then I guess you have to wait until another Recovery for FBEv1 is available.

I know someone already build Orangefox with FBEv1 but that is not ready yet to be published I guess.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
You're probably right.

Anyway, I have a question: I tried with all three version of the recovery to tap "decrypt data". It ask me to type a password or a pin, but no pattern. Then I set a PIN instead of the pattenr i usually use, but nothing, none of them can decrypt data partition.

Why there's not the possibility to unencrypt with the pattern?

And, is there a way to check whats kind of encryption my rom is using?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] woofwoof75:
It works! Thank you very much, mainly to install Magisk.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Here is a Orangefox Version for OP8pro using FBEv1
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Christos_A:
Hey, I booted the recovery using the fastboot boot command, then tried to flash it using the "Flash Current Orangefox" button under options. Issue is, from the logs it seems the recovery tried flashing itself to the boot image (backing up boot, patching boot etc), while our devices have a dedicated recovery partition. There was no mention of anything being flashed to the recovery partition on the logs.

I didn't try booting to either recovery or system after that, i opted to reflash the stock recovery/boot image of my rom using fastboot and then flash the recovery from there instead, but i assume this is not the intended behavior here.

I used the latest V13 erofs build of the recovery on an OnePlus 8T on EvoX A13
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Yes flash current Orangefox does not work on our Oneplus devices as that will flash to the boot partition instead of the recovery partition!!

I thought I had disabled that option in the latest Version. Have to check that!

So if you want to flash Orangefox to your phone you do it with fastboot flash recovery and the filename to the .img file of the Orangefox Version you want to flash!
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
Thanks! I'll try asap.

Is there a github of the project?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
https://github.com/SENSEIIIII/twrp_device_OnePlus_instantnoodlep
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
I've just tried this versions too, but the problem is the same: both boots, but I can't figure out how to decrypt data. Do I have to remove the pattern or set a different lock? Such as a PIN?

Anyway, how to check what is my rom using between erofs and ext4? Which partition do I have to check?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
With Devcheck app for example you can check the filesystem of the System partition if it is EXT4 or EROFS.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
Perfect: system is EROFS, but data is F2FS. Can it be that the reason that I can't decrypt it with OrangeFox?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
No thats normal that data is F2FS. Just system/system_ext is EROFS.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
I think I have to format data partition.

Now I can boot or install orange fox, but I can't decrypt data. What can I do without decrypt it?

Can I install ota updates? Flash zips from USB otg? Flash Magisk through the tool?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Yes you can install via USB OTG or ADB sideload
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
Today I had to formatted data to update the rom. I try to reinstall the recovery, and this time works well! Adb sideload works, flashing zips too, and also the data decryption.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] BRANDENDEUCE:
If we're on 12 now, can we flash this through magisk, or do we need to sideload?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
Anyway, I can't flash the zip. It says it's a package for istantnoodlep, and the device is an one plus 8 pro. Isn't the same?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Try to fastboot flash the img file to the recovery partition.

Thats the reconmended way to flash it
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
To flash Orangefox do it with fastboot flash recovery Orangefox.img .

The other ways to flash might not work or throw errors.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
That works, but I tried to flash the zip to use the Magisk addon. Anyway it's not a problem, I hold a Magisk zip on the device.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Hmmm. Strange. For my Oneplus 8T it worked to flash the Orangefox.zip file from recovery to get the Magisk addon installed to install Magisk.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] rmedure:
Great work here, thanks!!

I'm OP8 Plus with OOS12 (IN2025_11_C.21) installed both slots. I've had success so far with OrangeFox R12.1, EROFS and FBEv1. I've been able to successfully fastboot to OF recovery, decrypt data, make backups, and even fastboot flashed recovery to both slots and reboot recovery from phone working as well.

Has anyone been able to verify data restore working on IN2025 phone with this recovery?

Tried the OrangeFox-R12.1-Unofficial-OPKONA-OOS13-V14.img and it cannot decrypt the data partition.

Should I use another version?

EDIT: found the FBEv1 version

EDIT2: with the custom FBEv1 version, the touch screen doesn't work. Still there...
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
I guess the one who created the FBEv1 Version has not created a OOS13 Version.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] sms2000:
Very much like so. A pity, both v1 and v2 aren't incorporated in the same version. Should be not too complex.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
I'm using the FBEv1 version with EvolutionX 7.3 (A13): no problem at all
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Marcyvee:
I've just update to EvolutionX 7.4. The Update has overwritten the recovery with the developer one, but when i boot OF from fastboot the touch screen doesn't work anymore.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Yes because EvoX 7.4 is OOS13 based so you need to use a OOS13 based Version of Orangefox.

I have one for FBEv2 encryption but I guess for FBEv1 there is no OOS13 based Version existing yet.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] barisgg:
I managed to get the unofficial lineage os 20 and this on my one+ 8 with gapps and this as my recovery, able to unencrypt. Trial and error folks.

My device ist a 1+ 8pro Modell IN2023 EU-version, LPDDR 5(proved). I'm on LineageOS 19.Before installing LOS 19.1 i was on OOS 12.1 Rom.

I wanted to test OFox, because i will make easy backups of my Phone. So I tried to boot OFox recovery with "fastboot boot" command. But allways I ended up in a Screen with colored pixels in first quater of the screen. Rest of screen is black. After a few seconds the device shutdown. Phone only restarts by long pressing power and down bottom.

So i tried to boot LOS 19.1 recovery with "fastboot boot" command. It works without problems.

So my question is, must original OOS System version 11 or 12 be installed on my phone, to use OFox?

Don't want to flash OFox with the risk of brick the phone.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
For this Orangefox you should be on OOS12 or OOS13 on both slots.

When you are on OOS12 boot the OOS12 based Orangefox and for OOS13 the OOS13 based Orangefox.

Also if you have issues booting the V14 please try V13 of Orangefox.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] SchWeinSAuG:
Since i am on oos13 F15, i was able to boot with the oos113_v14 version of OF.

and backup all options ?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] greatestandroidfan:
Ok, tried the fastboot boot OrangeFox-R12.1-Unofficial-OPKONA-OOS13-V14.img method on OnePlus 8 Pro EU with crDroid 9 (A13, F.15 firmware) - and it boot to recovery! (y)

But - there is always one :p - it provides decryption of /data with PIN or Password only.

As I'm using pattern I'd always have to change unlock method to PIN before entering Recovery.

Wrote to both slots a & b permanently with:

fastboot flash recovery_a OrangeFox-R12.1-Unofficial-OPKONA-OOS13-V14.img

fastboot flash recovery_b OrangeFox-R12.1-Unofficial-OPKONA-OOS13-V14.img

The backup/restore of /data isn't very useful when we have root (it can be handled by Swift Backup or Migrate apps).

[OnePlus 8 / 8 Pro & 8T Cross Device Development] Jonas2802:
I got a dumb question maybe. I#m on a custom ROM thats based on AOSP on A12.1L. Devcheck App says im on EXT4 partition. SO what FBE-Version do I have to use. And what is FDBe?
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
If you are using Oneplus 8 Pro which has FBEv1 encryption and you are on OOS12 you need to use a recovery whith FBEv1 encryption. My Orangefox Version can only decrypt data on ROMs with FBEv2 encryption.

So this one works for OP8Pro OOS12. https://telegra.ph/OrangeFox-OnePlus-8-Pro-11-17
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Jonas2802:
Oh thank you a lot. How do i find out which FBE version I need
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
For Oneplus 8 and 8Pro almost only the OP8 series unified ROMs used FBEv2.

All others for OP8 and OP8 Pro uses FBEv1.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Jonas2802:
okey then I guess I have to go with the FBEv1 version as you've mentioned above:D

Booting the v1 Version i end in the QUalcomm CrashDump mode so i guess my ROMS firmware and the OrangeFox's firmware dont match, right
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
Yes exactly.

I guess the FBEv1 Orangefox Verison for the 8Pro is only for OOS12 based ROMs. That never got updated with OOS13 base afaik.

And if you are on a Android 12 ROM check if it is OOS12 based (or based on old OOS11).

And then you should make sure that you have OOS12 on both slots before flashing any recovery, otherwise you could end up in crashdump mode.

To get the same OOS base on both slots you can flash copy-partitions from recovery or flash my flashable firmware once which will get flashed to both slots.
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Jonas2802:
OKey, and being on a ROM that's based on AOSP, means the firmware is not based on OOS isn't it? So being on a AOSP based ROM there's no way to get OrangeFox working
[OnePlus 8 / 8 Pro & 8T Cross Device Development] Wishmasterflo:
No the firmware is always based on some OOS Version. AOSP or CLO/CAF has nothing to do with the OOS base.

So all ROMs for our Oneplus devices are based on a specific OOS base and that OOS firmware base needs to be on both slots before flashing any new recovery and ROM.

And the recovery needs to be on the same OOS base as your phone is on, otherwise touch screen does not work on Orangefox or it does boot into crashdump if you dont have the same OOS base firmware on both slots.
