Instructions

  1. Download Android 4.1.2 XXDMB2 Jelly Bean firmware to your laptop, extract its content and then download Odin tool 3.07 and extract its files, too. Your comp should now have these two files (among many others): .tar and Odin3 v3.07.exe.
  2. After the phone is switched off, you need to enter it into Download Mode and then launch Odin on the laptop.
  3. The next step, the one with number three, tells you to plug the Note 2 LTE GT-N7105 to your computer and then choose a couple of files. See what they are and how to opt for them below:
    .tar; you’ll gain access to it if you tap PDA;
    – tap Phone to opt for the file with MODEM;
    – click CSC and choose the CSC file;
    – tap PIT; now choose the .pit file.
  4. Step four sounds in the following way: check F. Reset Time and Auto Reboot; should the .pit file been selected in the previous step, then check Repartition, too, and then click Start.
  5. In step five, the action which will now happen will be the following: the handset shall restart and you will need to disconnect the Note 2 N7105 from your laptop. Go to About phone, which will let you know if the XXDMB2 Android 4.1.2 official firmware update is present on the device.
