How to Unroot the Samsung Galaxy Note 2 LTE (N7105)

When you install a custom ROM or a Tweak, chances are you may end up with a bricked device and the solution to get back to the original track is install the stock firmware. The stock firmware wipes off all the data on the device and adds the original firmware files, this unroots the device as well. Since the device goes back to stock, it also gets its warranty reinstated, the main advantage of unrooting a device. Luckily, the stock firmware for Samsung Galaxy Note 2 LTE (N7105) is available online and in the following guide, we’ve explained how you can flash it on the device easily. Let’s see how you can do so.

    Dear Mahesh, I’m using a N7105 but its not by T-Mobile. My baseband version is N7105DXALJ1. For whatever reason, my phone is unable to upload the latest software update. When I reboot the phone, official status indicates “CUSTOM” although I have never tampered with it. Can I use the aforesaid method mentioned by you to restore my phone to original factory setting hence able to update my software from JB 4.1.1 to JB 4.1.2. Thanks
