[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Bleyld:
Alright this may be a little bit of a long one, but I'm hoping I can provide as much information as I can to get as much help from you guys as possible. Now you'll have to bare with me. I'm not new to technology, but am new to rooting.

I have a Galaxy S4 US Version ATT I337 running 4.3 Base-band I337UCUEMK2. I've had it since the day they came out, and finally got too board with it, decided to root and look into a custom ROM. I rooted using the saferoot file listed below (I would link the tutorial/instructions I followed but I can't seem to find the link again..). Root works great, I get SuperSU and can use root access on apps like EZ Manager, Rom Manager, etc. So that's great.

I then decided I wanted a custom ROM. I've decided it's a tie between Miui and CyanogenMod.I figured I'd give MIUI a shot first because it's looks like a "cleaner" "newer" version. Either way, it's what I decided. I followed this tutorial here

Now I realize that's for the 19505 firmware, but I read a few places (here included:) that the 19505 version works clean on the I337.

I boot into recovery (Hold Volume Up+Power+Middle Button) and select boot from sdcard after I moved it over. It wipes all the data on the phone, then gives me an error stating something about signature verification (I can't give the exact, it happens pretty fast). Not a problem, just a bad file or download (even though I got it from the miui site). So I tried different download links, and different versions all with the same issue.

I figure, screw it miui isn't going to work. I'll try CyanogenMod. Same exact issue.

After a little more research, I find that CWM is the recovery program. So I look into it being an issue with that. I find that Rom Manager is the best way to get the most up to date CWM. Inside of Rom Manager v5.5.3.7 it says I'm using 6.0.4.4 ClockworkMod Touch. Well this brings up what I THINK might be the issue, and kind of confusing. The recovery I'm using isn't touch.. and it looks nothing like some of the images I see come up with CWM 5x or 6x, and has a lot less options that some people are saying I should have (ignore signiture verification blah blah blah) all I really get is to install from different places, or to wipe cache and factory reset.

So I figure great.. CWM is broken, screw that one too.

Let's get GooManager and try TWMP. Download it, Settings>Install OpenRecoveryScript blahblahblah. Click on reboot recovery, and this is another odd part. It doesn't boot into recovery, it boots into Odin Download mode. But not just boots into it, it boot loops it. I can get out of the boot loop by forcing it to shut down, then enter Odin Download myself, but instead of volume up, choose volume down to cancel restart phone, then it restarts normal. But if I just shut down, then power back on it boot loops it again. And now I can't get into CWM at all, which kinda sucks.

So as you can see, I've got quite a few different issues going on, and all I want it Miui or CyanogenMod. Ha.

Anyways, instructions? Suggestions? Help? I appreciate everything you provide, and thank you in advance.
