This will fix the orange icon for ya.

i'm from Mexico and my Razr HD is from Telcel

after flash the Retail Brasilian Firmware I lost my 4G LTE because the firmware has a diferent modem from Brasil LTE

for the people who lost LTE after flashing (like me) I have the solution

I just took the firmware from Rogers Canada and extract the modem_signed file and with this modem I have again my LTE from Telcel

I attached the bat file and fastboot files if somebody need it

i didn't attached the modem_signed file because my internet is very slow but you can download it from here

http://forum.xda-developers.com/show....php?t=1943879\\

you just put the modem_signed file in the same folder with the files attached and run the bat file, your phone need to be in fastboot mode

Awesome. Just flashed using retail brazil 4.1.2 and lost LTE along the way. This post is just what I needed to get LTE again. I'm in AT&T territory so our frequency is only shared by Canada and Mexico.

Mil gracias!!

Hi guys. I need help from you to get back 4G on my cel. The first thing I´d do was flash my cel with BR Retail ICS, with this ROM 7.7.1Q-144_VQL_S3-49 Service, the process was sucessfull. After that my cel only connect H+, loosing the capability to reach 4G. I make the process mentioned in this thread with no results.
1- Make the process with de archive modem_signed, obtained from FW Rogers Canada
Version: 7.7.1Q-144_VQL_S3-49 FULL
Android Version: 4.0.4
without results.
2- Make the process with de archive modem_signed, obtained from FW Telcel Mexico
Version: 7.7.1Q-144_VQL_S3-58 Full
Android Version: 4.0.4
without result.
3- Flash again my cel with FW Retail Brasil
Version: 7.7.1Q-144_VQL_S3-49 Service
Android Version: 4.0.4
replacing the file modem_signed, with the same named file from FW Telcel Mexico without results.

Im in Mexico DF and would like to enjoy the benefits of 4G service. Thanks everybody.

Try it with the modem files from the VIVO full firmware. Tha'ts what I did. I think the regions have to match for it to work. Rogers is North American. Vivo and Telcel should both be Latin American.

I got it 4G LTE in my cel.

Thank you stiffi2011, i soveld the problem by myself, but your answer help to me very much, the word "FILES" (plural) was very important to show me that i need more than one file.

The process was wich is described at the top of the thread, but i used two files ,modem_signed and fsg_signed, instead of a single one modem_signed.
Both file taked from firmware:
Telcel Mexico
Version: 7.7.1Q-144_VQL_S3-58 Full
Android Version: 4.0.4

Thank everybody. Unity is strength.

Ha! I did the same thing at first. Took me 3 tries to realize I needed 2 files. Glad you got it working.

All you need it's the fsg.bin file of your carrier and it should work I'm using the Brazil baseband with 4G by just flashing the fsg file
