Stuck at _ booting El Capitan from USB

So, I've been out of the hack game for a little while now and I'm trying to install El Capitan, but once I get to Clover, press enter and start the boot process from the USB to start the installation I get stuck at the black screen with "_" for about a minute before it reboots. I get just the Apple logo without "-v". I've tried safe mode with "-x" and then I get stuck with "Using Safe Mode _" I've tried with my kexts in 10.11 and in Other. I all different boot args. 

Anyone got an idea what is preventing me from getting past the first stage of the boot process? [► source]

BTW, I'm using "-v" and "nv_disable=1" boot args and I've disabled SIP in Clover config.

Making the installer drive

1. Connect to your Mac a properly formatted 8GB (or larger) drive, and rename the drive Untitled. (The Terminal commands I provide here assume that the drive is named Untitled. If the drive isn’t named Untitled, the procedure won’t work.)
2. Make sure the El Capitan installer (or at least a copy of it), called Install OS X El Capitan.app, is in its default location in your main Applications folder (/Applications).
3. Select the text of the following Terminal command and copy it.

   sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction

4. Launch Terminal (in /Applications/Utilities).
5. Warning: This step will erase the destination drive or partition, so make sure that it doesn’t contain any valuable data. Paste the copied command into Terminal and press Return.
6. Type your admin-level account password when prompted, and then press Return.
7. You may see the message “To continue we need to erase the disk at /Volumes/Untitled. If you wish to continue type (Y) then press return:” If so, type the letter Y and then press Return. If you don't see this message, you're already set.

The Terminal window displays createinstallmedia’s progress as a textual representation of a progress bar: Erasing Disk: 0%... 10 percent...20 percent... and so on. You also see a list of the program’s tasks as they occur: Copying installer files to disk... Copy complete.Making disk bootable... Copying boot files... Copy complete. The procedure can take as little as a couple minutes, or as long as 20 to 30 minutes, depending on how fast your Mac can copy data to the destination drive. Once you see Copy Complete. Done., as shown in the screenshot above, the process has finished.
