Recover LTE after Brazil firmware

rafa00 · Nov 27, 2012

Hi people,

this is my first post here

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

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

Great! So that Rogers firmware is OEM Right? Because that ****ty telcel has a whole page of its apps...

Any improvements that you can share? Battery life? Performance?

well, with the brazil firmware you will no have any app of Telcel and the performance I feel it a little bit faster but not much, the only thing that will not chance is the Messages icon because its stored in the sim card, if turn on your phone without your sim card you will see the original Message icon (blue) then if you insert your sim card the screen will be flash a little bit and the Message icon will turn orange with white

Ahh ok. Well I've read that removing all telcel's stuff was a huge improvement on the speed/battery life.
Maybe I will try this on the weekend.
Gracias!

Just to let you know, this does not work on CM10. It makes the modem unstable, and can't connect to LTE.

Anyway, thank you for your help.

hey

we can also flash the rogers firm full, just download from firmwares thread and open the firm file with winrar, choose the xml file and edit with notepad, erase the following lines

<step var="max-download-size" operation="getvar"/>
<step var="fb_mode_set" operation="oem"/>

save and ready to flash!!!

By doing this I recieve a "clean" andriod installation (without any telcel bloatware) and LTE??

I'm having problems during the flash.
I'm trying to install the rogers firmware over this telcel version and I can't do it unless I use the files from telcel
I'm using RSD Lite 6 and It says "failed to hab check for" with a few files like system_signed, devtree_signed, system_signed

What i'm missing? Do i need to unlock it first?

dashiell.cano · Dec 14, 2012

Telstra 4.1.2?
Does it have any bloatware?
I´m having issues with my phone since new. If I have LTE after a call my signal dissapears for a few seconds and then reconnects. This doesn't happens with 3g.
Is there an error with the original modem file from telcel?
My phone is damaged? I'm the only one having this problem?

Saludotes!
