[One (M9) Q&A, Help & Troubleshooting] MeltdownSpectre:
Okay, so the log I posted 5 minutes ago when mentioning clsA, that was using the old htc_fastboot.

I renamed htc_fastboot_3.0.9.2 to htc_fastboot and got rid of the old one.

Here's the result of that, also I typed flash zip firmware.zip as many times as required, because it kept asking me to flash again and again until it was actually successful, but even then it DOESN'T BOOT!

I'm sleepy as hell (it's 5:30 AM in Pakistan) and this damn M9 has ruined my weekend.

Piece of junk just doesn't want to boot!

Any other suggestions? PLEASE?
