Sprint Galaxy Note 2 root development board where you can find guides including rooting, unrooting, ROMs, Hacks, Overclocking, related kernels, and other development topics.
If you are unlocking your device bootloader, and rooting your device, the next logical step is to install what is called a Custom recovery. A Custom Recovery tool like TWRP or CWM provides a lot more functionality than available on the stock Android recovery that ships with your device. Custom recoveries include ability to flash custom ROMs, kernels, flashable OTA updates, and pretty much anything that needs flashing. A custom recovery also includes various maintenance tools which can help create a full backup of your existing ROM, and restore to it in case you are not happy with a new ROM you flashed. There are two popular custom recoveries available for most Android devices, Clockworkmod Recovery or CWM as it is popularly known as, and TWRP (Team Win Recovery Project). In the case of the Sprint Galaxy Note 2, TWRP is said to be more compatible as CWM tends to cause the odd issue here and there.
Here's a step-by-step guide on how you can install the fully touch-based TWRP Recovery on your Sprint Galaxy Note II. There are multiple ways to get TWRP up and running on your device and I am going to cover all of them on this page, starting with the easiest and the fastest method which requires that your device be already rooted. If you haven't done so already, you can use this guide to root your device and liberate it from carrier imposed restrictions.
TWRP Installation Guide for Sprint Galaxy Note II
A. Goo Manager App Method (Preferred and Recommended by the TWRP Team)
- Download & Install the free Goo Manager App from the Google Play Store
- Launch the Goo Manager app on your TMO Galaxy Note II
- Click the three vertical dots at the top right hand side of the screen to access the Goo Manager Options menu
- From the dropdown menu, click Install OpenRecovery Script (Indicated by the blue arrow in the screenshot above)
- Just click Yes to the prompts that follow
- Goo Manager will automatically download the latest version of TWRP recovery on your Note II
- To check if TWRP has been installed properly, just click Reboot Recovery from the Goo Manager options and boot into TWRP recovery mode
B. Recovery Flash Method
- Download the TWRP flashable zip file to your PC or directly to your device from --> HERE | MIRROR
- If you have downloaded the zip file to your computer, connect your Note 2 and transfer the zip file to the root of its internal SD card
- Power of the phone and boot into recovery mode. To do so, press and hold the Volume Up + Home + Power buttons together and release just the Power button as soon as the screen goes off, to enter recovery mode. In recovery, use the volume buttons to scroll up and down and the Home button to select options (if the Home button does not do anything, use the power button).
- In the Recovery Main menu, Scroll down to Install zip from SD card and select it using the Power button. Next select Choose zip from SDcard which should bring up all the contents of your Internal memory. Scroll down to the TWRP zip file you transferred to the phone memory in Step 2, (or to the Downloads folder if you downloaded it directly to your device), and select it using the Power button.
- On the next screen, confirm the installation by scrolling down to and selecting Yes-Install
- Android recovery will start flashing the TWRP recovery zip and will be done in a few seconds.
- Once done, go back to the main recovery menu and Select Reboot System
- To check if TWRP has been installed properly, just reboot your phone by pressing and holding the Volume Up + Home + Power buttons together till the screen flashes, after which the phone will boot into TWRP recovery in a few seconds
C. Odin Flash Method
- Download the latest Odin flashable .tar file for TWRP Recovery from --> HERE | MIRROR
- Download Odin from --> HERE . Once downloaded, extract the zip file to your desktop
- Make sure you have all the correct drivers for your device installed on you computer. If you don't already have them, you can get them --> HERE
- Power off your phone and wait for it to shut down completely
- Now we would be booting your Note II into what is called Download Mode. This is a special mode in Samsung devices, much like fastboot mode on other devices. Odin can only communicate with your Note II when it is download mode, and not otherwise. To do this, press and hold the Volume Down + Home + Power keys simultaneously till the phone turns on and shows a Warning!! screen with a yellow triangle. Then press Volume Up to enter Download mode
- On your PC, navigate to the folder you extracted Odin to in Step 2, and launch Odin by double-clicking the Odin3 v3.07.exe file
- Connect your Note II to your PC now using the USB data cable, preferably the one that came with the phone. Any microUSB cable should work, but I prefer to use the one supplied with the phone to avoid any unforeseen complications. You should see the message Added!! in the main Odin window like in the screenshot below. If you don't see the Added message, try re-installing the drivers, or try using a different USB cable or port
- In Odin, click on the PDA button, and select the .tar file that you downloaded in Step 1.
- Just make sure the Auto Reboot and F Reset Time boxes are ticked in Odin. They are usually checked by default though. Leave everything else in Odin as is
- Click the Start button in Odin to start flashing TWRP recovery to your device. Once Odin has finished flashing recovery .tar file successfully, you should see that the box to the the Top Left in the Odin window will turn Green with the status message PASS! ,
- Note: In case something gets messy, like Odin getting stuck after you hit Start button, or you getting a FAIL message at the end of the flashing process, do not worry. Just disconnect the device from the PC, close Odin, remove the battery on your device and re-insert it after 10 seconds, and repeat Steps 4-10.
- Once Odin has finished flashing the TWRP recovery file, your phone will reboot automatically. Once you see the PASS! status in Odin, it is safe to disconnect your device.
- To check if TWRP has been installed properly, just turn off your phone and reboot using the Volume Up + Home + Power button combo together till the screen turns on, after which the phone will boot into TWRP recovery in a few seconds
Take your pick from the method you find most convenient from the ones above, go ahead and get that custom TWRP recovery on your Sprint Galaxy Note II. Happy times lie ahead for rooted users, but having root access and TWRP just makes it all the more exciting
