Alrighty lads and lasses, got a bit of a problem on my hands. Been rooted on ME7 since the first time I booted up the phone. After seeing a handful of posts about SafeStrap and Hyperdrive now working for ME7, I wanted to take it for a spin. However, it appears that my S4 is plagued with the inability to wipe the cache or dalvik partitions. I get the "Failed" message in SS, and a quick "error" message followed by a reboot through stock recovery. Similarly, I cannot wipe data/factory reset through SS. I can do that through stock though. As I haven't been able to track down any pertinent information on this issue (a few random threads around the web with no real answers) I was wondering if anyone has figured out what the issue might be or if there is a way to remedy it.
