I've had my HTC One for a few months now and I must say I'm really enjoying it. I switched right after I got it to the GP rom, mainly because I didn't like the flipboard homescreen from Sense. But I've changed my mind, and I want to go back. But there's a small problem.
I'm not really great when it comes to installing ROM and stuff like that, so consider me a total noob. Alright, I'll get to the problem.
I can't flash another ROM. Why, you may ask, well that's because I can't enter recovery mode. It gives me an Android logo with a red triangle with a "!" in it. Well, I thought I'd have to flash a custom recovery then, so I tried that. But then again, the problem is my bootloader is (re)locked. Unlocking doesn't work, I've tried HTCdev, and Revone, but it doesn't work.
Now while trying that stuff, I've noticed a little red line in fastboot which wasn't there before. This is what it says:
So basically, I need to unlock my bootloader, to flash recovery, to install a new ROM. Can anyone help me figure this out?
Thanks in advance,
