The mp3 jailbreak method was disabled in firmware newer than 5.0.0.
You can use a RUNME.sh with my generic data.tar.gz.
You should try setting the bootmode idme var to main.
If you can boot to main using MfgTool, then you should be able to use MfgTool to boot to fastboot or diags.
In fastboot, do:
fastboot setvar bootmode main
or in diags, from a RUNME.sh (or from an SSH shell if you installed mmcblk0p2_ssh) do:
idme -d --bootmain main
Let me know how these work for you.
