Accidentally wiped /system. How do I fix this?

Hi! So friend 1 had asked me to help him root and flash CM on his S3 and I gladly helped. We were having a tough time doing it although I did it quite easily on friend 2's s3. Friend 3 chipped in to help us out by asking us to use Kingroot and let it root the S3. I thought it was ok and we let it do its thing. After it was "rooted" we tried flashing CM. There was an error during the process and it said it couldn't read the binary or something like that. I then wiped /system through TWRP thinking that it would revert everything back to stock. Well, obviously it wiped Android. I am so bad with Samsung phones xD Unfortunately, I did get ahead of myself and did not backup the phone when it still had Touchwiz. Good thing is, I can still access TWRP and download mode. I've already downloaded a stock rom for the s3. Now, how do I flash it? Are there any other solutions?
Thanks :)

Insane amount of crashes using Benzo, wiped and installed Bliss Pop now horrible batt

I started with Benzo and everything seemed fine for the first few days aside from an occasional 'This App' has stopped working crash. Things started getting worse, screen freezing, random reboots and then losing my data connections. It eventually became so unstable that it was stuck in a boot loop. I debated trying to see if I could get some logs and submit them over to the Benzo team but decided to just wipe everything and try another ROM. I settled in Bliss Pop. Today is my first real use and I am less than pleased with how fast I am draining my battery. I had it on the charger all night to 100% and have been watching as the percentage is slowly going down as I use the phone. According to my battery stats I will be dead by 10:00. That gives me 3 hours. I went from 100% to 75% in 42 minutes.

Suggestions?

I wiped android os from my iconia a500

Hi. I accidently did a system wipe on my iconia a500 with TWRP and I cant even install a rom anymore. This happened on my first attempt of installing a rom. Does anyone know how to re-install any rom (preferably 4.0+). Btw I was using Android 3.0.1 before it got wiped. Thanks!:D
