When I try to install MavROM 4.5 with Safestrap enabled (using 2.0 btw), after reboot I get just a blank/black screen. I've tried all the suggestions I've found online to no avail. I tested the D3-MavROM-4.5.zip file using 7zip, and it always has CRC errors. I've downloaded the file over 6 times now, and each file I test gives me CRC errors for broken files (each download had different broken files), and none has shown up as clean yet. I downloaded MavROM 4.0 and 7zip gave it a clean bill of health, so I tried installing it, and it was successful. Any suggestions? Also, the OP may want to take a look at the host file to check the zip for errors.
