Yes there were few tweaks in how mount is done due to which TWRP is not working! And if someone(like me) already flashed TWRP. You don't need to flash SBF all over again. Just install(reinstal) bootmenu using the snd init app and you get the bootmenu.. Later you can just flash the ROM zip again.. Simple!
Not necessarily, I'm surprised 2ndinit even worked for you when I did that it bricked even worse! Just copy the bootmenu folder in root explorer from your ROM/NANDroid and replace the broken one with it
