Help corrupted OS, having trouble flashing

First, apologies if this has been solved somewhere on the forum, as I haven't been able to find it.

My rooted Verizon S4 became unstable a few weeks ago; random re-starts, bizarre battery draining, inability to re-start unless connected to a charger, etc.. I did a factory reset and the problems persisted. I installed Kies and downloaded the original stock ROM, but Kies was unable to connect to my device. After poking around online, I ran Odin and tried to flash the stock ROM that way. Here's how that went:

<OSM> Please wait..
<OSM> SCH-I545_MDK_562219_Stock_Restore.tar.md5 is valid.

<ID:0/004> FAIL! (Auth)
<ID:0/004>
<ID:0/004> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)​

Now when I start the phone, I get the "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." message. Only Kies won't connect to my phone so I have no idea how to proceed.

If anyone has any suggestions, please help! I'm sure I left out some pertinent details, so let me know what else I need to tell you...

I had issues when I downloaded the update a few days ago. Found this [ODIN][TAR] I545VRUFNC5 Factory and No-Wipe … | Verizon Samsung Galaxy S 4 | XDA Forums to go back to FNC5.

When I did it, I had numerous app failed to start messages. Did a wipe and reset from recovery mode and all is well. I went to titanium and restored and then froze fwupgrade and have not seen the update screen pop up as of yet.
 
ok well the phone is at least functional now. not sure if it'll still be unstable or not.

is it safe to root and install a custom rom at this point?
 
so the phone is still re-starting randomly, but will not stay on after a re-start unless plugged in to a charger (battery at 80+%). not sure how the OS can still be corrupted if I just re-installed it; could something else be causing it to be so unstable?

Since it will stay on witht he charger, i am wondering if you have a battery issue. I recently read a post that talked about bulging batteries causing restarts. I just don't remember where I read it.

The poster said to take out the battery, lay it on a flat surface and spin it. If it spins easy, it is bad. I am not sure what 'easy' means.

The other thing to do may be to factory reset from recovery mode.
