[Guide] How to enable Quadband (850 Mhz)

This guide is made by me using information originally posted by vestigo.

This guide will make your L6 Quadband (enabling the 850MHZ)

I assume that your phone is connected allready or else check out the Getting Connected guide in the motoguide right here on MMM.

Programs you need:
P2KManager
XVI32

Now that you have the software you need to do this, we just have to pull the seems from the phone, edit them, and upload them back to the phone.
It’s very quick and easy. It took me about 10 minutes total to do this.

Steps to download the seems:

1.Open the P2K Manager software.
2.After about 5 seconds, the bottom status bar will say ‘Connected’.
3.In the bottom of this window, there’s a ‘Seem’ box. This is where
we download and upload the seems. Next to where it says ‘From’, type 0025, and next to the ‘To’ box, type 0025.

4.Press the ‘Download Seem’ button right below it. It will ask where you want to save this seem. You MUST leave the filename xxxx_yyyy.seem. Once you hit ‘Save’, it will save it with the name of 0025_0001.seem onto your computer.

Make a copy of these 2 seem files into another folder, incase you need to upload them again.

Now, it’s time to edit the seems:

1.Open the XVI32 software. This is a standard hex editing software package.
2.Click on the ‘File’ menu and choose ‘Open’.
3.Browse to the folder where you saved the Seem files.
4.Click on the 0025_0001.seem and click ‘Open’.

5.There will only be one piece of information in this file. Click once on the grid where you see the numbers showing up. I believe mine said 09 in the box before I edited it, and in the bottom left status bar, it says ‘Adr. Hex: 00’.

6.Click on the ‘Tools’ menu and choose ‘Bit manipulation’.

7.Bit 0 and Bit 3 will have a check in them when you open this window. This sets the phone to 900/1800/1900 band. Leave these checked and put a check in the box for Bit 1. This will change the phone to 850/900/1800/1900.
