OK so I just switched over from Apple to Samsung, and there are many differences between jail breaking and rooting. But really, all I would really want out of a root is two things: Be able to save games to my external SD card, and maybe get some free in app purchases later on. (My main concern is the SD card though.. I only have 8GB.) Ive already rooted once (I did it with Kingroot, because it seemed to be the only one click root I could use, because I didn't feel like using Odin) Well, I did something wrong. The root worked, and I got to save some new games to my SD. Then I shut off my phone, and then later went to turn it back on, and BOOM: It wouldn't boot, and there was a big yellow triangle with a exclamation point, with some text that I cant remember (I remember the word "kernel" was on the screen though, I think it said something like "the kernel is not secure" or something along those lines). I was able to reset my phone using Kies 3, although I lost everything. Now, though, I really want that extra space, and I can only use it with root access. The only thing that I found that maybe could have prevented that is if I unlocked the OEM. But I'm not sure. I'm hoping someone could help me and root my device, but this time not mess it up. Because I'm new to this I imagine I missed something the first time around, so it wouldn't surprise me if I missed something big.
tl:dr: I rooted once, messed up my phone, I want to root again, but I don't know if there's a stable root for my phone

 

Sorry Im late, but my model number is SM-G530W

 

Ok so, here was my main question. I didnt enable OEM unlocking. Would have that been the reason why my phone didnt boot?

 

I stole this from http://mobile.tumblrvip.com/tag/smg530w/ but here is exactly what my phone said:
SM-G530W Kingroot tripped knox ‘Custom binary Blocked by FRP secure fail kernel’
"Hello all, I used the kingroot app on my galaxy grand prime g530w ( not the computer version ) and it tripped knox. Now when I boot my phone, it says ‘Custom binary Blocked by FRP, secure fail: kernel.’ "(Copy and paste is great)
But this is spot on what happened to me. I know its probably an annoyance that I'm asking, I just dont feel like messing up my phone again. The reason I messed up is because of not enabling OEM? Thanks in advance for your patience man, I'm slow to reply

 

Well cant I use https://play.google.com/store/apps/details?id=darkslide.com.supersumepro&hl=en .? Then wouldnt I be able to switch them?

 

You lost me on the last sentence, but I don't think I need to do that.I'm just doing this so I can move apps to my SD card, and I just wanna say switch over to SuperSu to say I have it in case I do need it. I'll try this out on Sunday, and it should work. Ill let you know what happens

 

Ok well, the good news is my phone boots (yay). But I think Im stuck with Kinguser, at least for the time being. I downloaded SuperSu Me and it isnt going past "processing". Oh well. At least I can save apps to my SD card. Thanks for your help
