    Please help! I can't install twrp! My oneplus one is running oxygen os 2.1.4. I can run the commands fine but when I try to reboot my phone into the recovery it gets stuck. It is just a black screen with the oneplus logo (nothing else). It stays like this for 20+ mins. What can I do?

    hey guys, can any1 help, i managed to get custom boot image and when i need to transfer supersu it says device not found, and when i go to fastboot and type fastboot devices it's there.... help pls

    installed a driver that recognized adb as android device but i cant copy the file to phone. i says it cant find supersu.zip in that folder although i tried several times and even renaming it...
    edit 2:
    extensions was not show, that's why it said no file found... but now that i converted it from .rar to .zip it says it's missing md5 file.... grrrr..... step by step i'll get there

    edit 3:
    Seems like the supersu file i downloaded first was crap, downloaded another 1 installed like charm.. Android is starting... I was never more happy to see that written on the screen :D

    1st root gone well after 7 hours hahahha

    If the phone is stuck in a bootloop (or bricked, i'm not sure), is there a way to flash? I can get it to fastboot but because it won't boot normally, i can't set USB debugging and CM recovery settings

    If you can access in fastboot mode use fastboot command but you'll lost all your data

    COS 13.1, can't unlock

    So, I was rooted and running COS 13.0. Recently, I flashed the latest COS 13.1 stock ROM using TWRP... I thought I had de-selected "Update Cyanogen Recovery", but apparently not because it has locked the bootloader and installed the Cyanogen recovery.

    Now I am unable to unlock the bootloader... the tamper bit is set to true. When I use
    fastboot eom unlock
    It simply re-boots to the Cyanogen recovery.

    Is there something different about COS 13.1 that doesn't allow the bootloader to be unlocked with the usual method? Has anyone else had this problem?

    Hi guys, I was following this guide, but right now I'm stuck with the rooting step. I have adb driver installed as per the link given, but when I tried to execute the command "adb push update-supersu.zip /sdcard", I got the error that says "device not found".

    1. Have I executed the command wrongly in any way? I did rename my zip file to supersu
    2. Could it be I have conflicting adb drivers installed? I tried "adb version" and I got a return msg of "adb version 1.0.31"

    Any advices pertaining to this adb push method will be greatly appreciated. Thanks!

    So I think something is up. When I unlocked bootloader, I ran "fastboot oem unlock" but my data did not get erased. I kept going with the process, and my phone shut off like it was supposed to, but now I cant get it into fastboot. The phone boots up just fine right now, and all my data is still there, so I'm kind of at a loss for what to do.

    Solved it by using the Qualcomm service tool.
