    iRajeshRajput , Sep 20, 2015 :
    Relocked the bootloader on Oneplus2 and again try to unlock the bootloader

    C:\adb>fastboot oem unlock
    ...
    OKAY [ -0.000s]
    finished. total time: -0.000s

    Now this time there is no notification on the phone screen and phone reboots automatically. Now flashing the Android logo from last 5 minute.


    Not able to boot in recovery mode. Only fastboot mode is working.


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


    Solved the problem with this guide :- https://forums.oneplus.net/threads/mega-unbrick-guide-for-a-hard-bricked-oneplus-2.347607/

    First 2 method didn't work for me, solved the problem with 3rd Method :)

    That's clever. From @DaxNagtegaal (for OPO but still applies here):
    'Important note: re-locking your bootloader can cause serious problems, don't ever re-lock your bootloader without contacting me first. I've warned you.'

    Did it work? Can you do fastboot oem unlock again? Were you locking it to return the phone?

    No that's not what I meant. Since you have a working fastboot, you can flash the TWRP recovery and then flash Oxygen via recovery. Read the full guide.

    I have locked unlocked boot loader in nexus devices and htc. Nexus devises are the most easy. Have not unlocked opt bootloader yet
