  1. We now turn our attention to the update steps that will offer a successful procedure. Unzip, for starters, the content of the two packages that are now on your notebook. Odin tool 3.07 and .tar.md5 are the two most important files you should keep a close watch on. Power the phone off next.
  2. Then enter it in Download Mode with these instructions: simultaneously press and hold Volume Down + Home + Power, let go once Android’s logo shows its face and then press Volume Up. After you’ve completed this, you need to launch, on your notebook, the Odin as Admin and then have your I9505 plugged to your laptop.
  3. The connection will have happened only if you are greeted with this message along with a yellow ID:COM box: “Added!!”. When neither of the things we mentioned happens, you have to use one of these solutions: use a different USB port or flash the USB drivers once more.
  4. After you experience a correct plugging, you have to move on to the next set of guidelines. Which should begin like this: click on “PDA“, choose the file with the .tar.md5 in it, move on to “Phone” and click on it, choose a file which comes with MODEM in the name, tap “CSC”, opt for a file that has CSC in the name, tap “PIT” and opt for a .pit file instead.
  5. Now do as follows: turn on Auto Reboot, Repartition (if you selected the file with a .pit extension) and F. Reset Time, then click on “Start”. The flashing is going to begin, so wait till the process ends. As soon as it does, you will see your handset restart.

  7. The way to see whether or not the update has been achieved: open “Settings” on your handset, then look for the upgrade file in the “About phone” section. If the new XXUEMK8 stock firmware is there, you can enjoy your updated device in all its glory. But if the firmware is not there, you will have to repeat our guide.

At any point in our tutorial, your phone may remain frozen in booting animation. This is easy to solve: just enter the handset in Recovery Mode, then reboot it after you select “Factory reset/Wipe data” and “Wipe cache partition“.
