Some time ago I decided to root my Samsung Galaxy Note II Android phone. Not out of necessity, but more out of curiosity to see what would happen and to get a feeling for the process.
The operation itself was really easy to perform and I ended up with a rooted device in the end. Recently, I have been trying to update the phone to the new Android version released for it.
Doing so using Samsung Kies or the phone's internal update check would result in a "firmware modified" error message which basically meant that could not update the phone the normal way.
I did research the issue and discovered that I had two options. The first, two download a stock ROM for the device, appealed the most to me and I decided to go down this route.
I fired up the phone in Download Mode (by holding down the following buttons on restart or boot: Volume Down, Home and Power)
Once in the mode, I connected the device to the PC, started Odin, selected the stock ROM under PDA, and hit the start button.
This worked out just fine at first, and everything seemed to have gone according to plans, until the phone rebooted.
My providers boot animation would come up, and then the Samsung logo. The animated logo would not go away however, and I thought at first that something was still being processed in the background.
After I waited some minutes, I realized that this was not the case. Did some research on that as well, and found out that you had to clear data and cache as well if that happened.
I had to boot the phone into recovery mode by holding down Volume Up, Power and Home until the boot logo of the phone would appear. This starts the recovery mode. Here I had to run the following two commands (using Volume up and down to navigate and power to select):
After I ran both commands, I selected reboot and the issue was fixed. The Samsung logo appeared for a short time, but the boot process continued after that allowing me to enter the phone's Pin number and proceed.
While I had to reconfigure most of the settings and preferences, and go through the on-screen help again (annoying), I was finally able to download and install the latest firmware update from within the phone.
