  • This is a complex and risky operation, so as usual a backup is being recommended. Also, by installing the CM10.1 Jelly Bean 4.2.2 ROM on your Galaxy Note 2, the data will be erased as a system wipe will be performed. Because of that make a Nandroid backup and save everything you need to before going any further (contacts, messages, EFS, market apps and so on).
  • Root the US Cellular Galaxy Note 2, or else you will not be able to complete the tutorial.
  • The warranty will get void, so try not to mess thing up; just follow my directions and everithing should be fine.
  • For restoring the warranty downgrade to stock ROM or update with an official OS released by Samsung and suitable with your version of Note 2.
  • Install a custom recovery image on your phablet; this tool can be flashed only on a rooted system and it will be used on the update procedure.
  • Then, because you will have to download some files, a Windows running computer must be used.
  • Don’t forget that your phablet and its USB cable must be there too.
  • Enable the USB debugging option on your device and if you notice that there is less than 60% power left, go and plug in the charger.
  • Deactivate the security protection (antivirus, Firewall and so on) from both Galaxy Note 2 and computer before starting the update process.
  • This guide should be used only by those who own the US Cellular version of the Samsung Galaxy Note 2 (model number SCH-R950); applying this CM10.1 Jelly Bean 4.2.2 Custom ROM firmware on a different handset will make you brick your device.
