    EDIT: When flashing back to CM11S don't reboot in between fastboot flash commands!!!!!! This seems to have been what causes this issue.

    Hi,

    I know I'll probably get some hate for this but here goes.

    OxygenOS comes with a new bootloader. I tried to reflash Cyanogen 11S using this bootloader and it had hardbricked my device (no signs of life at all).

    I've been flashing ROMS for years and years - I'm no noob so I can only assume there is something in the OxygenOS Fastboot whch doesn't play nicely with Cyanogen 11S/Kit Kat


    I hope I can recover from this if not hopefully OnePlus will be able to advise.

    Just thought I would warn everyone please be careful!!!!!!

    I encountered my issue after flashing rpm.mbn rebooting into bootloader then it just died.

    EDIT:

    To everyone asking about why not just do a nandroid restore this would result in issues with the radio and other partitions not being brought back to stock.

    Some instructions that could help unbrick your devices.Thanks @FanboyOne and those on the original thread

    Good News Everyone! My phone now lives to flash another day after working through the above after "resting" my phone overnight!

    I think Oneplus should replace it for free. They never mentioned anything about this potential issue.

    I've reverted back to cm11s no problems. Just used my twrp backup. I would say that most likely when flashing oxygen it flashes a new firmware. So I reflash cm11s firmware before restoring my backup. I take it it doesn't turn on. Not able to get to fastboot? But it does vibrate still when you hold power. What you need is to recover your phone with the hardbrick recovery thread somewhere on here or xda and go through each step.

    Do you think there's any way you could recover from your hard brick?

    There are a thread or two somewhere here and on XDA that are worth trying. Will provide a link if I could find them.

    I think most of users must be trying to revert back from oxygen os to cm11s , and boom opo service centers will be full of people wanting replacement .

    Hard brick = unrecoverable. The device needs a new motherboard now.

    Keep us updated here because i just finished downloading cm11s and still i am afraid of flashing it . There is no opo service center near by so i still fear pretty much . If anything worked please write down the procedure here .
