    Did that - the ' cannot read' error is gone now but after typing adb sideload... it just says installation failed on the OP3 with a message in the windows command prompt just saying "Total xfer: 0.00x" - any idea bout that?
    Thanks for your help!

    hey !
    I was unrooting my device through following your instructions. By the Point 7 everything is going right BUT at point 8 when I try to sideload my OTa.zip it show some error sorry I did not note that error ( but basically its means that Ota.zip can't be sideloaded ). after that I became worried I don't want to Bricked my device, So I Follow other instructions from other website but it messed up all. Now my phone don't shows any recovery options in Boot loader. when I select Recovery mode It Shows "decrypting" and stuck at 98% 99% after loading. Fortunately My phone is in working conditions.

    I am uploading one screenshot may be it will help you to understand my Situation.

    Now please tell me what should I do now ? Please Reply ASAP.

    and I still have TWRP in my phone.

    Hey Buddy, Great article, saved me no end of bother!

    It's a big thread, so admittedly, I haven't read all of it...

    If it helps anyone, I came across an issue while sideloading the ROM.
    "Error: protocol fault (no status)"

    This was due to older version of ADB/Fastboot drivers.

    I installed the All-In-One Tool from XDA.
    (Thanks to Mauronofrio)

    Worked Flawlessly!

    Many thanks again.

    @calvinistmac I am thinking of getting back to stock but I used a toolkit to unlock my oneplus 3 but I haven't rooted it yet is it still safe to use this method BTW I'm pretty sure the program just automates writing the adb commands and another question should I update to oxygen os 4.5.1 before I update to oreo since I'm currently on 4.0.3?

    If you follow the guide, it'll completely return it to stock.
    Also, it'll clean install to the latest version.

    Most of the tools do as you say, automate the commands to save typing them in.

    The advice i'd give... and Emphasise... Backup all your data!

    Is it safe for me to relock bootloader even though I've used a toolkit to unlock it?

    I have one more question the reason I am relocking my bootloader is because dm verity doesn't let me flash any rom except oxygen os ones, so is it still safe? I have TWRP 3.0.4-1

    Yeah each time I reboot my phone and when I try to boot into recovery through my phone it takes to the stock boot loader even though I have TWRP 3.0.4-1 installed and if I want to access TWRP I need to use the toolkit / adb commands
