I used this Hellscore Kernel Manager app to download a version of HellScore Kernel and Flash. The app gave me an option to download the Kernel <hammerhead..xxxxxxx>, I selected it and flashed away. After a reboot, my phone was hard bricked. I am quite sure the version of the kernel, or the bootloader it packages along, are NOT tested/verified for Nexus 5. There was no way to unbrick the phone after you do this. Please note, if you are downloading the HellScore kernel from his d-h.st/users/hellsgod respository, this kind of messup never happens. This app is the culprit for auto downloading a non-tested kernel that overwrites the /boot partition with a wrong one - thus hard bricking the Nexus 5.

Had I seen this post / idea before - i could have saved on the replacement Logic board that the LG service center suggested.

Thank you!

well.... it's just a matter of finding the right search terms I guess. the problem here is that there's no error and the first time you hit it, you have no idea what the hell is wrong.

I mean, for the first 15 minutes or so, I thought the phone was completely toast. then I lucked into the secondary and realized that if I can get into that, at least I'll be able to flash stock. I can certainly see people just giving up and getting it replaced.

as an aside... If THIS didn't hard brick the phone, man, you must really have to put in effort to completely do this phone in.
