[Galaxy Note 3 General] Benny Bosser:
This used to be a thread on how to disable the air command pop up sound, but it wasn't really a success. So I thought let's change it into a baseband/modem/bootloader upating guide. I know there are a bunch of guides on how to do this but I keep seeing people struggle with it, so I hope this helps :D

Prerequisites:

- Smartphone

- Computer

- USB cable

- Patience (it's still a virtue :D)

- Reading ability (some people seem to lack it nowadays ;))

It probably won't happen, but just in case :D

Now there are two ways to do update:

1) through flashing the latest firmware

2) by grabbing the modem/baseband/bootloader separately and flashing them manually

This is why most people don't manage to properly update their baseband/modem/bootloader: when updating don't boot into download mode through the reboot menu (this will lock your baseband and therefore it won't update). You have to boot into download mode using the hard keys. To do so, press the home key + volume down + power button at the same time. Hold them until you see a screen that asks you whether or not to continue into download mode.

Method 1: flashing official firmware

When you have a fast internet connection with a big download limit, I highly recommend this method. In this way you're sure everything gets updated at once.

- Grab the latest firmware at www.sammobile.com

Go to firmware. There you search the firmware for your device by typing your model number in the search box. You can grab the firmware for your region of another one, it doesn't matter that much as long as you're sure that the devices have the same chipset (snapdragon <--> exynos). Download the desired firmware. It's the official firmware so don't worry about tripping knox (if you haven't done so already of course :p).

- After the download is complete, start Odin.

For the people who don't have Odin yet, make sure you have Samsung kies installed (Link: Samsung Kies)

Download Odin (it's in the firmware description on sammobile) and install.

- Open Odin

- Put your device in download mode following the instructions in red (if you can't find them, you must be really blind! :p) and connect it to your computer with an USB cable.

If Samsung kies is properly installed, the box that says 0:[COM7] (the one in the left top corner) should be blue or yellow depending on the Odin version you downloaded.

- Click on AP and add the firmware you just downloaded.

You don't have to change any of the other settings.

- Hit start

Just wait till Odin says pass. Your device will automatically reboot.

You can check your device information by going to settings and checking about device or by typing *#1234# in your dialer.

- Enjoy :D

Method 2: flashing everything seperately

If you're low on available download data or you should don't want to flash an entire rom, this is the method for you.

- Search for your devices baseband/modem/bootloader (you can find them here on XDA) and download what you need.

- Open Odin (for how to install/download/what you need, see method 1).

- Add your bootloader by clicking BL

- Add your modem by clicking CP

- Add your baseband by clicking AP

You don't have to change any other settings in Odin.

- Hit start

Wait for Odin to say pass, your device should automatically restart.

You can check your device information by going to settings and checking about device or by typing *#1234# in your dialer.

- Enjoy

Hope this helps you guys :D
