Can I install galaxy grand 2 official 4.4.2 Kit kat firmware that you installed in your mobile in my galaxy grand duos (I9082) which is running on stock official 4.2.2 jelly beam?

No, you can't. There is no official kitkat update for Grand duos GT-I9082.

Boot in safe mood and see if things improve. If they do then a bad or corrupt app causing the issues.
Otherwise hard reset, if still no then flash the rom again via odin.
@axe.effect
Kies or Odin. No difference

To go into safe mode,

1- Power off the device completely.

2- Press and hold the Volume down key, then press and hold the Power key.

3- When the device vibrates, release only the Power key. Keep holding the Volume down key unitl the device boots up completely.

After booting up, safe mode will appear on the bottom left corner of the screen.

Use your phone in safe mode and then see if battery drains quickly or not and report back the results.

Safe mode disables user installed apps, which are usually the culprit for quick battery drain.

Battery drain can be due to system apps or user installed apps. Use of safe mode will determine that. Once we find out, then we can guide you better.

Also check these two things.
1- Make sure that all your apps are updated.

2- Also check firmware updates.
Settings > about device > software update.

Ok I flashed the KSA rom which was posted in previous page.
Now the thing is, I'm not getting signals, it says "Not Registered on Network".
Now I can't even flash my old Indian rom and even the steps that you have provided aren't working. Odin is saying "FAIL".
What to do now? :S

Why you have flashed KSA rom as Pakistani region firmware is present. And as i said earlier to post screenshots from (Samsung Info app) so we would know what csc and modem you are running.

Download firmware: G7102XXUBNK2_G7102OJVBNK2_PAK - SamMobile

Now don't panic, its just a modem issue, .i.e. incorrect modem. Flash above rom with odin. disable antivirus other programs, use genuine usb cable and make sure you have drivers installed.
If you get any errors in odin, post the screenshots here.
Don't forget to rinse before and after in recovery mode.

Can you spot the problem ?
You haven't flashed the KSA rom either. What did you flash btw.

Wrong csc, modem etc.

Flash the other asap, and please pay attention to the numbers and versions. they are written for a reason.
