Rooting the Android operating system that is running on a phone or tablet can be a complicated business. There are many reasons why people want to have root access or a custom recovery installed, and often people do not understand whether they need to have both of those things or not.
There are plenty of reasons for the confusion. For starters, installing a custom recovery is usually able to to be done as soon as you unlock the bootloader without having to have root access. However, there are some root apps out there that can help people install a custom recovery too. That is one of the reasons for people getting confused.
Rooting, for the most part, is always about installing apps and what those apps can do. There are root apps out therefore installing custom recovery and even root apps out there that offer the one-stop shop for installing custom ROMs.
The ROM Manager is one of the root apps out there that is well known for showing people what custom ROMs are available and providing them everything they need to get the ROM installed. That said, the act of installing a custom ROM in itself does not require root access. A custom ROM can be manually installed by unlocking the bootloader and then installing a custom recovery. It is just that if you want to use an app like ROM Manager or ROM Toolbox to help you with installing the new ROMs then, the root access is required before you can use those applications.
Details We Should Know
- Chainfire was running the LRX22G.P901UBU0BOI2 firmware build number when developing the rooting tool in this guide. You do not have to be running the same firmware. You need to be running on the Android 5.0.2 Lollipop and have the SM-P901 model number only.
- There can be more software updates that roll out for the Samsung Galaxy Note Pro 12.2 in the future, and some of those can bring new bootloaders with them. A new bootloader can sometimes stop the CF-Auto-Root tool from working temporarily. These bootloaders are usually only present in new versions of Android, so they do not often affect our guides. If you have a device that does not boot after flashing the CF-Auto-Root tool, then it is likely because of a new bootloader. Leave a message on the CF-Auto-Root tool thread at the XDA-Developer’s website with the new recovery image found in the firmware creating the problem for Chaifire to see and he will update the files, so they start working again.
