The AT&T model of the Samsung Galaxy Note 2 can be easily addressed regardless the issues that are currently causing malfunctions. All you have to do is to follow and apply a few dedicated operations and the Android core system will be once more smoothly running. So, that’s exactly what you can learn by resuming all the guidelines from this tutorial: how to manually unbrick the AT&T Samsung Galaxy Note 2 model number I317.

I should clear an important aspect right from the start: through this step by step guide you can learn only how to manually fix software related problems that are issued within the Android core system. Unfortunately, if a hard brick is involved you won’t be able to use this guide for troubleshooting your AT&T Samsung Galaxy Note 2 I317. In that situation you will have to take your smartphone back to service and ask for an experienced technical assistance – however, if the warranty can’t be reclaimed you will have to pay for these services.

As for the soft related problems, this tutorial can help you address almost everything starting with general bugs, lags, force close errors or alerts and ending with more complex malfunctions like battery drain, heating situations, signal strength problems, total blackouts and so on.

Usually, these types of issues are caused by: a malware, a program that stopped from working, inappropriate apps or custom operations that are applied on your Samsung Galaxy Note 2. In term of custom operations I am mainly referring about stuffs like gaining root access, installing custom recovery images, updating with custom ROMs, removing bloatware and start up programs, overclocking or undervolting CPU frequencies, installing custom kernels and several other tweaking procedures that aren’t supported by Samsung or by Google.

The troubleshoot process will consist in flashing, or better said, in re-flashing the stock Android firmware on your AT&T Samsung Galaxy Note 2 – so, you can now refresh the Android core system by reapplying the Android 4.4.2 software. In this way you can get rid of malware, you can stop the unresponsive programs and you can restore your smartphone back to its initial state.

That also means you will revoke root access, relock the bootloader, reinstall the stock recovery image, re-apply the bloatware and re-ensure the default / factory restrictions. Overall, you will take your device back to its initial state along with the pure Android firmware that is however customized and optimized by Samsung especially for your AT&T Galaxy Note 2.

The flashing process can be done through Odin, a great tool that is developed and offered by Samsung. Thus, everything will be kept safe and secured.
Anyway, before applying the steps from down below you should consider in trying several other troubleshoot solutions such as: rebooting into Android Safe Mode and uninstalling the apps and programs that are causing the malfunctions, making a hard reset for wiping the system of your phone, or clearing app data cache if you are dealing with a boot loop or with any other similar problem.

Of course, before beginning the troubleshoot process, if possible, backup your Samsung Galaxy Note 2 I317. It is important to save your personal data, info, accounts and files or else you will end up in losing what’s important for you. You can easily and quickly take care of the backup by syncing your Note 2 data with your Google Account, by using backup and restore apps from Google Play or by using built-in cloud storage platforms.

For the unbrick process you will have to use a computer that runs on Windows. On your AT&T Galaxy Note 2 you must become a developer (tap 7 times repeatedly on Built Number from “menu – settings – about phone”) and then have to check the USB Debugging field which is located under “menu – settings – developer options”. Charge your smartphone – even if your phone can’t be currently turned on. If it runs low on battery life it can get switched off while you try to unbrick its Android core system and in that situation you will only manage to mess things even worst.
