If you want to install custom ROMs using a custom recovery such as CWM or TWRP on your Verizon Galaxy Note 2 SGH-i605, you will need to unlock the bootloader.
This is for older builds, for latest Unlock method, see here instead.
Do I need to unlock bootloader if I have another Galaxy Note 2?
NO!!! Only Verizon Galaxy Note 2 comes with its bootloader unlocked, thanks to Verizon. So, please do not try this UNLESS YOU HAVE A Verizon Galaxy Note 2 SCH-i605!!!
So, let’s go ahead and unlock our bootloader.
Step 1. Before we begin, go to Settings->About phone on your Verizon Note 2 and see that last couple letters under Build number, it should say VRALJB.
Step 2. Once you are on Build number VRALJB, you can proceed. Power off your Verizon Note 2 then boot into ODIN download mode by holding down Volume Down, Home Center, and Power buttons together for about 5 seconds.
Step 3. Hit Volume Up button and connect a micro-USB cable from your Verizon Note 2 to your computer.
Step 4. Go ahead and download GalaxyNote2UnlockVerizon.zip and unzip. Then run Odin3v3.07.exe file by double-clicking on it. (You must use Odin v.3.07 for this older Odin v.185 will NOT WORK!!!)
Step 5. Make sure you see a light-blue box with a random COM number. If you don’t see that, please download and install Samsung USB drivers.
Step 6. DON’T TOUCH ANYTHING ELSE but click on the “PIT” button and choose the file “sch-i605-16gb.pit”.
Step 7. Next hit the “Bootloader” button and choose the file “BootloaderBaseline2.tar.md5.gz”.
Step 8. Hit the Start button and this will flash a custom PIT file and Bootloader so your Verizon Note 2 can be ready for bootloader unlocking.
Step 9. Once your Verizon Note 2 reboots, make sure USB debugging is checked under Settings->Developer options then connect a micro-USB cable from your Verizon Note 2 to your computer.
Step 10. Next make sure the USB mode in set as “Media device (MTP)”, you can find this by swiping down the notification bar after connecting your micro-USB cable.
Step 11. Go back to the unzipped files and run CASUAL-SuckItVerizon-Injection9.jar by double-clicking on it. You must have Java installed to run this file.
If you don’t have Java installed on your computer, goto Java.com and install it and re-try this step.
Step 12. Hit the “Root and Unlock Me Now!” button to start the bootloader unlocking process.
Step 13. Your phone will reboot twice and show this warning screen. Although it looks same as the regular ODIN warning screen, it is not, this is a special “unsecured” download mode where you can flash a custom recovery and bootloader. Go ahead and hit Volume Up button.
Step 14. Run ODIN again and hit the “Bootloader” button. Then choose the file “SuckItVerizon_Odin_Package2.tar.md5.gz”.
Step 15. Hit the start button and this will flash an unlocked bootloader and TWRP recovery on your phone.
Step 16. Your phone should reboot into TWRP recovery. If you got to this point, CONGRATULATIONS! You’ve finally unlocked your Verizon Galaxy Note 2! You can now install custom ROMs, kernels, and more.
Please be aware that after unlocking your bootloader, it’s not ADVISED to use ODIN at all. You should only use ODIN only if you are going to unroot your phone so you can return it to Verizon for warranty purposes. PLEASE DO NOT FLASH ROMs using ODIN!!!
