Long story short, I had issues with my texts not being received. I tried wiping the phone and re-rooting (using root-stock found on this website - I can link if need be?).. Anyway, I went so far as to do a factory data wipe, which clearly wasn't a very good idea (I'm a bit new at this root business)..
Anyway, I ended up to the point where I'd reach the Android Setup Wizard, and start to go through it and it would crash.. Upon reboot, the phone would completely freeze at the second "SAMSUNG" logo (the white lettering). After this, I tried using odin to just flash the stock ROM to the phone via the PC, but neither the PC nor odin actually "see" the phone. (I have the drivers, but PC reads the phone as "USB Hub" for some reason) I moved on to other things...
I used bluetooth to put cwm and root-stock back onto the internal memory after removing my external SD card, and flashed cwm no problem. Everything was going well, and it even said it installed the root-stock (I did a data wipe beforehand).. Upon reboot, I now reach "Samsung Galaxy Exhibit 4G" logo, and it continually reboots in a loop. I can still access recovery mode, but I don't want to proceed any further without some outside input, considering I don't fully understand what's going on.
I'm aware that the phone seems to be "soft-bricked," because before I flashed cwm and root-stock, it was "working" in terms of being able to receive calls (and make them, after opening the contacts from inside a call), as well as send and receive texts via the notification bar. But the weirdest thing is, before I went the route of re-flashing the root/cwm, it wouldn't show me a homescreen of any kind, I couldn't use my menu button, and my home button was pointless to touch because it went nowhere. It was just a black screen (not a background, but completely black void) with a statusbar at the top.
Anyway, I'm currently stuck in a boot-loop and I'm very curious if there's any way I can fix this phone without using odin, because the phone isn't recognized by it or a PC, so I'm stuck using the device itself to do things. I'm VERY hopeful that someone takes the time to read this and offer any input they can, because I'm currently without a device and I have no means of getting another phone at the moment.
Thanks in advance for reading this, and for any input that you guys have to offer. Hopefully some day I'm not so noobish at this >.<
