    i have found a way to revert to stock without stock recovery..you will need paranoid android and the update stock rom for oneplus 3..first flash paranoid android with gapps then let it boot up..i know some of us are getting an error but thats ok..now turn off phone and boot to recovery..your going to flash the stock update for the oneplus 3 on top of paranoid.
    do not factory reset yet..let it boot and you will see the oneplus 3 stock boot animation..i reached a point where i had a black screen but the bottom buttons on..now you turn off by keep pressing power button and go to recovery by pressing volume down plus power same time and go to recovery at this point just wipe data,cache and dalvic and boom your back to stock..

    But as i understand this is not an official Update.
    Has anybody to be known to have flashed it and still have a usable Phone, with Stock Recovery?

    Nice.
    Can I flash it with TWRP or does it have to be done via ADB Sideload?

    Smart thinking as the ota file will probably overwrite everything and both roms share the aosp base. Im doing this right now , so far so good, got passed the boot animation , Android is now updating apps

    You can try to use TWRP but if it doesn't work, then use ADB sideload

    Thanks for helping out so quickly! I ended up just flashing the 3.1.3 OTA update and got the phone working again! Unfortunately, root check says it's not rooted. I tried flashing SuperSU again but no luck (caused device to hang at loading again). Root checker provided the attached information which may help.

    Hey guys,

    sorry if this is a dumb or already stated question.
    But is the phone decrypted or encrypted from default?

    Ordered my OP3 now and i want to unlock bootloader immediatly after unboxing, so im ready for flashing twrp, custom Roms and supersu in the future (without loosing internal storage).

    But that encryption thing totally irritates me, since i never got in touch with that.

    So only necessary thing to be ready for the future steps is to unlock bootloader with OEM unlock per fastboot, or any other important things to do?

    Thanks for help! :D:)

    I had already answered that... you need to format the user data in fastboot.

    Currently encryption is forced on Stock ROM. If you want to get rid of encryption, then reboot to fastboot and execute:

    Code:
    fastboot format userdata

    This will wipe your data partition, including storage!

    What SuperSU did you flash ?

    You can flash full zips for the updates usually available within 24 to 48 hours of the OTA release.

    Yes its possible but not recommended.

    Are you talking about Xposed ? All you have to do is to flash xposed v85 sdk23 ARM64 and you are done.

    Can be flashed via TWRP

    You don't have to do all this, just OTA and you are back to stock recovery

    I thought I had read every single post since I joined the thread. Anyway, thanks for answering twice :D.

    So, I'd make a Nandroid backup and format data. I assume I can do that in TWRP as well or does it have to be done with fastboot?

    Once rebooted, I can then restore all apps/settings from TitaniumBackup and be back in business, correct?

    Sorry for the redundancy I just want to make sure I understand and do the right thing.

    Well stock rom has forced encryption, so let it be like it till you are using Oxygen.
    Once you move to CM Based roms or other platforms you can do that. I prefer doing it via fastboot.

    Hey, the one plus 3 is shipping with an unlocked bootloader, doesnt this mean I just skip step one and get to recovery and rooting , or should I still unlock it .

    I know dumb question, have not manually rooted a phone myself from scratch , had a friend do it and then learned about flashing and certain other stuff. Im going to be doing my first every unlock, flash and root myself this time.
