Custom Recovery on Virgin Mobile L710
I'm not new to flashing Android. I'm on Virgin Mobile's L710, and I'm rooted. I'm having trouble getting a custom recovery to function on my phone. I've tried CWM and I've tried TWRP. I am flashing them via Odin v3. Also, and related...Nandroid Backup Manager gives me permission errors when opening it.
