Neither, using 4ext as all zips flash through it.CWM/TWRP just runs an aroma installer, and when it comes to the installing part it ends instantly, no errors whatsoever.4ext is very nice, except that it doesn't have a sideload option but i'll live with it.
What you described is most likely Aroma's fault, not CWM/TWRP. That thing is glitchy as hell.
How can I move from cwm to 4ext. I have cwm installed. My phone is unlocked and s-on.
