An Android enthusiast will always be challenged to mods their devices, even though their devices are excellent out of the box. You might be one of them who think that the phone always need improvements, then trying to get it from a third-party by gaining root access, install custom recovery or flash a custom ROMs. But before you do that, it’s safer to find out how to unroot and restore the Samsung Galaxy Note 4 back to stock condition.
When you customize the phone’s software, there’s a chance that you will get a difficulty when you are executing the mods or afterwards. Some of the problems that you might encounter like noticeable lag, force closes, random reboots, stuck in bootscreen or even soft-bricked phone, although it’s a rare case if you do it right.
When you got this problem after doing lots of changes in your Note 4’s software, then the first step is to perform a factory reset, to restore custom settings to factory default. But if you still got that problem, there’s a well-known action to recover the Galaxy Note 4 back to stock. The short explanation is we will flash the official firmware from Samsung to our phone by using Odin3 utility.
This procedure can be done on most Samsung Galaxy Note 4 variants, including the Verizon (SM-N910V), AT&T (SM-N910A), T-Mobile (SM-N910T), Sprint (SM-N910P) or other variants, it depends on the availability of the stock firmware for your specific models. Here are the requirements to get it done:
