Ok, so I have some corrupted files on my internal sd that won't let my phone boot normally and I was wondering if there's any way too completely wipe internal sd without being able to boot far enough for usb to be detected? Another words my phone freezes as soon as it tries to prepare internal sd. Also I can get into download and recovery just fine and I've already OC Jf6 back to stock. there was no lagfix involved so not sure what became corrupted. I know CWR is still on internal sd because I can still access it via 2e recovery reinstall pkgs. Any help greatly appreciated.
