    Hey guys,

    I have stock OOS 5.0 with Magisk Beta v14.5 installed and I am trying to get back to full stock and relock the bootloader.

    Every time I get to step 7 of the tutorial, where I flash stock recovery, the command prompt yields OKAY results but the phone stays stuck in the OnePlus bootlogo screen. I am forced to reflash TWRP recovery to get back into system.

    Have redownloaded the stock recovery file multiple times and ADB drivers are working fine.

    I need your help. Thanks.

    If it's not working you didn't do something right. Detail out for me exactly what you did.

    Thank you for your reply.

    I ended up going about it a different way because, even following your instructions to the letter, stock recovery just didn't want to flash. I used this tutorial here and that worked for me:

    Thank you for your expedient reply on this. Really appreciate it.

    I'm glad that worked for you. Sorry my method fouled up the recovery. It's odd because the other day I went from a custom 7.1.2 rom to OOS Oreo (the stable one) with my method and it worked just fine. Seems that every phone is different.

    I was glad I had a moment to respond quick. That doesn't always happen. Have a good one!

    Where do GApps and firmware play into this?

    Do I need to flash new firmware before doing this? I am currently on microG LineageOS build using whatever the most recent Nougat firmware beta is. I want to upgrade to 5.0 Oreo stable build, with stock everything and locked bootloader.

    I would like Play services to be working on the device, is that included with the stock ROM image or does it need to be flashed separately? If so, when? During this process? Or after?

    Oh for crying out loud! Did you actually read what I wrote in the first post? If any of the above stuff you mentioned was necessary I would've put it there.

    Everything you need is there in the first post, and everything you need software-wise is included with every release of OxygenOS, including Oreo.

    Please next time read more carefully.

    UPDATE: I have updated the guide to version 4.0.1.

    The reason is I added another piece of information as well as bumped up the Open Beta version numbers.

    Happy unrooting!

    It's probably a driver issue. Go to your device manager and make sure fastboot is showing up in the device manager. If not you'll need to reinstall the drivers. This does happen on occasion.

    I honestly have no idea here. I'm not in front of your phone so I cannot diagnose your issue. If you followed my steps to the letter you should be sailing smoothly.

    i tried again and its not working,
    I took my mobile to a service centre and they told if the system is rooted then there is a risk of hardware issue if original version is installed.
    They are not using adb or fastboot to do the recovery.
    What should i do?? should i ask then to do the recovery on my risk, will there be any issue??

    If it hasn't moved start the process over.
