So you have the new (TWRP) boot menu, and when you choose Recovery, it doesn't load up? That is new, as the new boot menu is TWRP. Perhaps fastboot flash the recovery image in the ROM zip instead of test8?
Other than that, waiting for it to load is about the only thing you can do, unless you can get an adb shell in recovery. If you can get that, perhaps rm -r /data and /cache (but absolutely not /system), check with @rbox first though.

I was able to flash test8 using fastboot, but it didn't help. The recovery.img in the ROM zip is just the original one posted on the thread isn't it? If so, that's what I had before I flashed test8.
