IntroductionOne of the most common problems seen on this subreddit is a bricked OnePlus. Being bricked can be caused by a wide range of issues, and simply describes the fact you cannot access the normal system of your phone. It's not nice when it happens - especially when you've done nothing wrong or out of the ordinary. Fortunately, there is almost always a way to fix it that doesn't require sending your phone off for repair, assuming there is no hardware damage. In fact, most of these fixes will take you under 10 minutes.This post will try to address the most common situations of a bricked OnePlus and the methods to fix them. However, if at any point you need some further help - please ask!I know this is a bloody long post, but believe me when I say that you will save yourself much more time and heartache by reading it carefully and fully than jumping in and going too quickly.
Is it soft or hard?This is the first question you should ask yourself when you think you've bricked your phone. Soft-bricks are generally very easy to recover from, hard-bricks will take more work.Soft-brick: When rebooting normally, your phone may bootloop, get stuck at the bootscreen or be blank after the bootscreen. You CAN access recovery and/or fastboot.Hard-brick: When rebooting normally, your phone may get stuck at the OnePlus logo, have a blank screen, vibrate or simply show no signs of life. You CANNOT access recovery or fastboot.The simplest way to check if you're soft-bricked is to hold POWER + VOLUME DOWN. This key combination will restart your phone into recovery mode. If you are able to access this, you are soft-bricked.If this fails, hold POWER + VOLUME UP to reboot into fastboot. If you are able to access this, you are still soft-bricked (albeit in a bit of a worse situation).

Okay, So I just updated to the latest cyanogenmod 12.1 update through TWRP. As you describe, its hard-bricked. It won't vibrate upon trying to turn it on, no logo comes up, no screen reaction at all. I can't even get into TWRP. So the phone seems to be 'dead'. But When I first plug it into my laptop, it does nothing.

There is a program called unetbootin that makes the process very easy. Let me know if you would like more info on thisedit2: updated the OP with full instructions on how to use the iso. We need some help. Can someone familiar with booting to cd or usb test the iso image out? Follow the bottom set of instructions in the OP, but instead of typing 'stormer', type 'tester'.
It will not flash anything to your device as long as you only use 'tester'.We need to know if the device is recognized in the live environment, and typing 'tester' as the codename will look for the device and display what block it's mounted on. Please let us know as soon as possible if it recognizes your device and what block it is on. My Boost Max won't boot.
I was out and had 11% power left. I tapped the battery booster button in the All in One Toolbox which redirected me to the play store to download and install Battery Booster Lite (by Imoblife Inc). I installed it and selected the smart battery option trying to maintain what was left of my power so I could take pics at my daughter's performance. However we were instructed to power off all phones.
I shut my phone down and afterwards it would not boot at all. Even when I connected it to the charger once I got home, no red light, no charging indicator on the screen. It's been at least an hour and still nothing. PLEASE HELP!! My Boost Max won't boot. I was out and had 11% power left.
