Please Help : SCH-I535 4.3 updated topic

Hi all,
I don't know whether I'm posting my question in the correct forum or not.
My Phone is SCH I-535. Accidentally, I upgraded to 4.3.

I have rooted and downloaded rootchecker from play store and it is rooted successfully.

Basically, I did a big blunder last time, by flashing a wrong ROM altogether. Flashed the International Version ROM and it hard bricked, and it was a mess. I could not use my phone for almost 6 months since, I did not have time to work on this. So now, I got the phone up and running and I did not know that, I should not accept the 4.3 update. So I did accept and now I'm on 4.3 and rooted.


Basically, I have 3 requirements.
1. Get a clean, fast, simple ROM, which has only essential Apps and no bloatware - CAN ANYONE SUGGEST ANY ROM-SCH-I535,4.3,ROOTED
2. Get the HotSpot feature working - I downloaded foxfi, and it is working fine. But if the stock Hotspot feature works, then it will be great. I don't like many Apps in my phone. I feel they make it a bit slow. I want my phone to be as fast as possible.
3. Increase the Brightness of my screen. I read somewhere about the kernel modification or something. I tried to do that last time and I messed it up badly.

So, I did not want to do anything stupid this time and I'm posting here.
I have read different threads and there is a lot of information, and that's how, I was able to root this 4.3 SCH I-535. But I don't want to do anything on my own, with out expert advice. So I'm posting here.

Any help is highly appreciated. Thank You.

[Q] 4.3 OTA bug for SCH-I535 topic

After updating to the OTA 4.3 my S3 now has a glitch causing the screen to occasionally black out, mostly during phone calls but also after screen timeouts when i hit the power button to turn the screen back on it'll stay black for awhile, the menu and back buttons light up and the touch sensor still works even when black. it work flawlessly before the update. I tried to root and was successful at it using the saferoot method but because of the know being lock I can not install a custom rom or recovery and the problem was still there because I was still using the 4.3 rom. So I used odin3 vs3.07 and put the stock rom back on and unrooted and the problem is still there. does anyone know how to fix this glitch or does anyone know how i can go back to the 4.2.1 rom or install the 4.4.2 rom because 4.3 has been nothing but a headache for me.
