(for your Novatel Wireless Merlin XU-870 or your DELL Wireless 5510)

What do my tutorial for you ?

Add the 7.2 Mbps support for your Novatel Wireless Merlin XU-870 or your DELL Wireless 5510

card

Use your DELL card on a x64 bits laptop!

History

The 7.2 Mbps firmware for the XU-870 (or DELL Wireless 5510) was very hard to find! I spent many

nights googling the web to find it. After find this firmware I was disappointed because the Novatel

Wireless Merlin updater doesn't want to flash my DELL branded card. So I decided to find a way to

update my fuc**g 3G card. If you have an x64 laptop and a DELL card I think you will be happy to know

that DELL don't provide ANY 64 bits drivers (One more reason to debrand you DELL card!)

For information :

Making bad operations on your card can brick your device! I am not responsible of your ACTS!

Upgrading the DELL Wireless 5510 to 7.2 Mbps

For a XU_870 you can use directly the 101.9.00 firmware updater but for the DELL there is no way! We

can't upgrade the card with the same firmware update! So we use the old firmware updater (version

9.5.03) to flash the new 7.2 Mbps firmware. For this we have to swap two files during the upgrade

processes.

Upgrading a XU-870 branded by DELL is more complicated. You have to follow this tutorial to flash and

debrand your DELL Card. After this, your card will be recognize like an Novatel Wiresll Merlin XU-870

card.

Download the following file :

NVTL__FUU_800_9.5.03_S1.exe

The original firmware installer for Merlin XU-870 ver 9.5.03

U800.nvtb

The extracted 7.2 Mbps firmware

XU870.cache

The configuration file

The Novatel Drivers

The Novatel Wireless Merlin drivers

1. Download and install first the Novatel driver for the card.

2. Launch the NVTL__FUU_800_9.5.03_S1.exe installer, you will see this screen (sorry I'am French

as you can see on the update's screenshot)

Don't click on "Next"

3. Go to the temp folder (On my Windows Vista : C:\Windows\temp). You will see an "U800.nvtb",

this is the old firmware. So replace the 10,5 MB "U800.nvtb" files by the 12,9 MB "U800.nvtb" files

you've downloaded from this website.

7. At this point the new firmware is written on the 3G card.

In the temp folder you will see a new *.cache file. Replace the "*.cache" files by the "XU870.cache" files

you've downloaded from this website. So take my *.cache file and rename it with the same name than the

old one (here : L7101106001991_001.cache).

The configuration file contain all information about the device except IMEI. So The branded information are

stored in this file. So restoring my *.cache file will debrand your DELL card to be an original Merlin XU-870
