Newbie needs urgent help with flashing and rooting - Galaxy S 4 Q&A, Help & Troubleshooting

Hello Everyone,
I have decided to try flashing a custom rom on my samsung galaxy s4 (i9500), since I'm tired of waiting for further updates from Samsung. My phone is stuck on 5.0.1 and for months the most annoying problem that I have is the massive battery drain whenever Wi-Fi is on. So I am seeking help from you guys on how to start this tedious process?
I am newbie and I would like to know what files are needed.
Also, to fellow i9500 users, can you suggest what is the most stable (no battery drain issue) custom rom?
Thank you .

[Q] Kernel? Android 4.3

Hi guys
First off, i'm a complete noob.
I have a Samsung galaxy S4 GT-I9500.
I want to be able to install stock android on my phone. I've spent hours reading forums and websites to find answers.
I have already rooted the phone and installed a recovery, CWM touch or something(I still don't completely understand what it is)
After the root and backup using the recovery, what must i do next to install android 4.3?
Sorry for the noob questions but i would be grateful if someone can help me.
Cheers

There is no unusual battery drain in 4.4.2 if not factory reseted do it, it will fix your problem, u can't go back to 4.3 now.
If you do a google search you will see there are many many users affected by the battery drain bug. Im yet to find a fix.

S4 Downgrade

Hi everyone, I currently have a samsung galaxy S4 I9505 phone running android 4.3. I upgraded to 4.3 via Odin not via the inbuilt software update. Im wondering if it is at all possible to downgrade to 4.2.2 because with 4.3 their has been an introduction of a lot of bugs to apps such as Chrome and Spotify. These bugs have since been really getting annoying and the only time I didn't have to deal with them would be when I was running 4.2.2.
Alternatively can anyone tell me if upgrading to android Kitkat for S4 would potentially fix these problems?
Any help will of course be greatly appreciated and even if no help can be given thanks for taking the time to read this post.

Forget the word Downgrade
this is not possible without problems (and they are many)

S4 wifi not turning on

Hi guys I was wondering if you can quickly help me. I was happy with S4 but since I was giving it to someone else I decided to flash everything stock 4.4.2 XXUGNE5 modem GNG2. Now wifi does not turn on. Should I flash different modem? Any help is welcomed. KNOX is triggered so flashing custom things is not a problem. Thank you in advance.
