Overclock your Samsung Galaxy S3 using Ninphetamin3 custom kernel step-by-step tutorial  

Samsung Galaxy S3 GT-I9300 boasts with one of the fastest processor out there: 1.4 GHz quad-core Exynos and only its big brother, the much-appraised Samsung Galaxy Note 2 might compete with it. But you can’t really say you have too much horse power in any gadget, so people will always try to hack what seems to be working perfectly to make it work even better or to break it. 

 
The people from XDA were curious about how far one can overclock Samsung’s flagship phone’s processor and they introduced the Ninphetamin3 kernel for Galaxy S3 GT-I9300 which speeds up its 1.4 GHz quad-core Exynos to 1.8 Ghz. More than that, the overall phone’s performance will be improved and the user will gain more control over the smartphone’s features,  with CPU Voltage Control Interface, Compiler optimizations, Removed Debug overhead and many more. 
 

Samsung Galaxy S3 overclock

 

The people from XDA were curious about how far one can overclock Samsung’s flagship phone’s processor and they introduced the Ninphetamin3 kernel for Galaxy S3 GT-I9300 which speeds up its 1.4 GHz quad-core Exynos to 1.8 Ghz. More than that, the overall phone’s performance will be improved and the user will gain more control over the smartphone’s features,  with CPU Voltage Control Interface, Compiler optimizations, Removed Debug overhead and many more.

In order to proceed, you’ll need the following: a Samsung Galaxy S3 running a stock ROM, a PC running Windows and the handset USB drivers installed on your PC (by Samsung Kies).

First, you must remember to enable USB debugging on your smartphone, then disable any security software: antivirus, firewall, etc, as long as it might interfere with the actions implied in this guide.

Second, make sure to backup all personal data on your phone, in case you’ll need stuff like contacts, SMS, MMS, Internet settings, Wi-Fi passwords, the actions taken will erase all these. For further info about the backup procedure, consult this guide about  creating local backups of your mobile data.

Third, download these files: Ninphetamin3 custom kernel (ninphetamin3-release-1.2.0.tar.md5, 4.0 MB and Odin3 v3.04 (Odin3_v3.04.zip, 456.59 kB) . Then, let’s the party begin.

Maybe it would be wise to see if your phone can enter into download mode, doing the following operation: switch it off and then reboot it, pressing and holding down simultaneously the Home button, Power button and Volume down key until a warning message comes on your smartphone. To continue into download mode you’ll just press the Volume Up key.

It would be wiser to check if your phone is at least 60% charged, to ensure that your S3 won’t turn into a senseless brick after the process. You’ll better read once or twice the procedure below and then try it with your phone.

If all these worked smoothly, you can proceed, so pay great attention to the methodology:

After you extract Odin3_v3.04.zip into a specified folder in your PC, just switch off your smartphone and then reboot into Download Mode, as you’ve been advised to do.

After holding the Home button, Power button and Volume down key simultaneously, a message will appear and you’ll be able to continue in Download Mode.

 Go to the folder where you extracted the Odin files and run Odin3 v3.04.exe , launching Odin on your PC.

Connect the computer with the S3 using the USB cable and Odin will display “Added!”.

Important: Go to Options to ensure yourself that  “Re-partition” is not checked. If so, uncheck i.

Click the PDA button in Odin and search for ninphetamin3-release-1.2.0.tar.md5 file.

By only clicking  Start you’ll flash the kernel to your phone. Wait paciently for this procedure.

Your device will reboot and a PASS message will be displayed on the screen.

When you’ll see the Samsung Logo on the screen, disconnect your phone from the computer.

If you see a FAIL message, take a deep breath and do the following:

Close Odin and disconnect your Samsung Galaxy S3 from the PC and then remove and reinsert your battery.

Re-check if you’ve used the correct files and you have really disabled the system tools on your PC.

If you did all the operations above in the correct order, now you have a faster and smarter mobile phone. Just pay attention to anything fishy like your phone getting too much hot and perform the reverse operation, if it’s the case. If not, just enjoy!

The instructions below are intended to use with the following phone: Samsung Galaxy S3 GT-I9300, so please do not try these tricks on other phone models, they’ll must certainly not work. I will be not held responsible by anything that might happen on your device if you apply my instructions and there’s no guarantee that they’ll work under every specific circumstances.
