Yuzi download

Ive been trying for 4 days now to unlock my bootloader on my Z5P, it says ok and what not on cmd, I restart my phone and its reset but the bootloader still says bootloader unlock allowed: yes ive tried using flashtool but it says my device is unsupported
Im using the E6853 on 6.0.1 MM
I have made sure OEM unlock is enabled and that stays enabled after reset, the fastboot drivers are installed, and Ive tried flashing a custom kernel with an error writing to boot, any help? :crying:

Hello, i have a htc one mini and i need to unlock the lock screen.

Ive Googled, Ive Binged, I have searched here until there is a sea of followed links and still am clearly missing something that must be right in front of my face.
I would like to put a custom rom on my tablet. A custom recovery is a necessary step from what I understand. So many tutorials including the one at TWRPs website themselves dont mention that you need to have an unlocked bootloader first. I have tried the TWRP Manager app and it says that I need an unlocked bootloader before I can flash a recovery.

How do I unlock the bootloader? I can not seem to find a tutorial or even any discussion of it in the Galaxy Tab 3 section here and I have spent many hours today trying to figure it out.
I stumbled upon the app Flashfire. It seems promising. It it what I need?
