Help 4.3.3 root problem, no updates, system status custom

[OmegaXI5]

Hello. So I purchased my S3 2 months ago (was my first ever android phone) which was in a neat condition and I had no one else to check it. It costed me around $110 (second hand). It had many problems while I was trying to set it up my own way, but i finally settled down for it.

However just a few days ago, I googled something and I realized that my device is rooted so i used an app to unroot it (UnRoot device something. Purchased app) and SuperSU was uninstalled however system status still shows as custom.

Pressing volume down, home and power button on starting phone takes me to a place with triangle where it asks that you want to download custom ROM or not :s This phone's completely screwed and I can't buy a new phone due to financial conditions.

Anyone knows how can I return it to its official state (everything [factory reset wouldn't work. tried it])?

 

[Mikestony]

Sure!
Go to sammobile.com , set up a free account, search for and find the latest firmware for your specific model number and carrier and flash it with ODIN.
There are simple instructions there along with links for downloading ODIN.
Just a heads up, either disable or remove KIES (if installed) as ODIN and KIES don't play well together.
Do you have the drivers installed on your computer for the S3?
If you need more help, just ask and we can help find what you need

Ok so got an account there now the thing is.
I live in Pakistan, I cannot find the correct PDA or CSC for my phone. It's
CP:- I9300BUUGNB1
CSC:- I9300VFGGNB1

Even selecting no country and applying filter wouldn't bring these results up :/

Looking up in Pakistan as country wouldn't do any good either.

EDIT* I forgot to mention it's problems. Whenever I play some game, it's battery life becomes like 1 % per 1 minute and it wouldn't go more than 1h 30m when gaming. It's pretty low otherwise too (not battery fault. switched 3 batteries)
And it's brightness wouldn't reduce. Not with any app etc. But filters like NightMode do the trick and still battery consumption is the same.

That's a UK CSC code, the network is Vodafone.

The most recent firmware (released 01/09/2014) is I9300XXUGNH4 (CSC: I9300VFGGNH2)

 

[OmegaXI5]

So should I install that one? I9300XXUGNH4 one

 

[Slug]

So should I install that one?

It's always advisable to have the latest version installed, yes.

Thats currently being downloaded but regarding the steps

• Extract (unzip) the firmware file
• Download Odin v3.10.7
• Extract Odin ZIP file
• Open Odin v3.10.7
• Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
• Connect phone and wait until you get a blue sign in Odin
• Add the firmware file to AP / PDA
• Make sure re-partition is NOT ticked
• Click the start button, sit back and wait few minutes

The reboot part, it brings up do you want to download a custom ROM (Didn't do above steps yet).
Do I connect the phone there and wait for blue sign in Odin? (There's also a very big triangle)

 

[OmegaXI5]

Ok so I did the steps above. Device is unrooted and status changed to official! However I still cannot reduce brightness and battery is consumed like fudge ._.

Losing 1% per minute when gaming isn't really uncommon. What is battery life like when it's idle?

 

[OmegaXI5]

6.5 minutes result with no powersaving and wifi on:- 2% battery consumed. I just removed the screen timeout time and started stopwatch.

A 20 minutes video clip takes about 8% in power saving.

Update** It's a 3000 mAH battery that I got from ebay.

Should be able to adjust brightness in settings -display, either set to automatic 0r manual adjust.

 

[OmegaXI5]

Nawp. Wouldn't do. It's auto, in manual it wouldn't increase/decrease.
It's maximum 24/7

Found a few apps in Play Store to control screen brightness. Don't have a link,but did search for screen brightness. Maybe one of them will help

 

[Jfalls63]

https://play.google.com/store/apps/...s+app&pcampaignid=APPU_1_1VodVoKSF8TUeJ_Un9gJ

Found one

 

[OmegaXI5]

Wouldn't work

 

[Jfalls63]

Hardware issue, maybe? You flashed new firmware and tried apps. Never ran across that issue before with screen.

 

[OmegaXI5]

You think it's an issue with screen o.o If I remember correctly, the cellphone is refurbished (the screen was open once before it came in my hand).
How stupid I was to think that this wouldn't cause me issues -.-

 

[Jfalls63]

I'm thinking more of problem with motherboard. Screen supposed to do what motherboard and program tells it to as far as display. All other screen functions working? Color and touch?

Yep. Everything aside from brightness if fine.

Thing I like most about S3 and S4 is the way they are built. You can get to all components thru the back of the phone. I have been given a few that were not working and been able to Frankenstein them together to get one going. Would be nice to try another board if you could get your hands on one.

 

[OmegaXI5]

I can order one from ebay (there isn't any proof that something is real here in pakistan if you buy from local stores). Will get back to you guys asap.

 

[Jfalls63]

Very easy to replace, lots of how to videos and tutorials on Web.

 

[OmegaXI5]

Aside from the motherboard stuff, I just realized that I can't make any calls etc.
It says "Not registered on network".
So I installed Pakistan's firmware to no avail.
Help ;3?

 

[Jfalls63]

Other than correct Sim card and APN settings for your network provider,not much else to check. Not sure about Pakistan but in US, a bad IME,ESN will have your phone blacklisted

 

[OmegaXI5]

That wouldn't mean that my phone is stolen etc :s?
