For those of you who have bricked your Galaxy Note GT-N7000 for some odd reason (although that’s hard to do) or you simply want to “un-warrantize” your phone so you can return it for warranty, you always have the option to “unroot” your phone completely back to stock.
This will get you back on stock Gingerbread ROM. And if ICS is available by the time you read this, you can still unroot using this method and do a software update on your phone (or use Samsung Kies) to get it all back to stock.
Step 1. Put your Galaxy Note into download mode by holding down the Volume Down, Center button, and the Power button together for about 10 seconds.
Step 2. When you see the warning sign, you can press Volume Up button.
Step 3. Connect a micro-USB cable from your phone to your computer.
Step 4. Next, go to this XDA thread and find the appropriate stock ROM for the country you bought your Galaxy Note. If you can’t find your country, try something close. And you can actually flash any of them, it won’t harm your Galaxy Note as you can always flash another country’s stock ROM. They are compatible across all Galaxy Note GT-N7000.
Step 5. Once you download the appropriate stock ROM, unzip it and you should get either one file or multiple files.
Step 6. Next, download ODIN program, unzip, and run it.
Step 7. Choose “PDA” and choose the stock ROM file you unzipped earlier if you have one file.
If you have multiple files, choose the file ending with “user_low_ship.tar.md5″ for PDA, choose the file that contains “MODEM” in its filename for PHONE, and choose file that contains “CSC” in its filename for CSC.
Step 8. Make sure you get a yellow highlighted COM on ODIN. If you don’t, download Samsung Kies and install. After installing, unplug and plug in the micro-USB cable to your Galaxy Note and you should get the yellow highlight.
Next hit “Start” and after 5-10 minutes, your phone will reboot and you should be back on stock ROM.
Step 9. You will also need to do a factory reset afterwards. To do this, hold down Volume Up, Center button, and Power button for about 10 seconds until you see yellow messages.
Step 10. Choose “Wipe data/factory reset”.
Step 11. Choose “Yes”.
Step 12. Reboot and your Galaxy Note GT-N7000 should be back on completely stock ROM.
Now, this unrooting process doesn’t erase any of your personal media files on your internal storage or SD card. If you are returning your phone for warranty, do copy those (that you want to back up) to your hard disk and erase it.
Have a Mac or Linux?
You can also do this using the open-source Heimdall for Mac or Linux. The steps are nearly identical except you don’t need to install drivers for Mac or Linux.Need Help? Follow/add me on Google+, Facebook, or Twitter!
