Claro BR 4G LTE Problems

[liquelt]

Hey Guys,
I am here to relate an problem that I am having where I live.
The thing is. I have now 4G LTE service and I got a new 5GB 4G data plan...
On the carriers system they say I am ready to go to acces the blazing fast speed they show on commercials.
But the Max I am having is 3G service...
I know I have 4G service because when I search for networks it shows CLARO BR 4G, CLARO BR 3G and CLARO BR 2G.
Can it be related to the ROM I am using?
I am using the Retail BR 4.1.2 with the modem and fsg files from my carriers 4.0.3 ROM.
Can this be related to an old SIM card?
I dont think so, because I changed to this carrier less than one year ago and they say on their website that the 3GReady SIM is also already Ready for 4G.

What else can I do??

Settings -> More... -> Mobile Networks -> Select network and make sure Auto 4G/3G/2G is enabled. I believe Auto 3G/2G is the default one, I know because I do use 4.1.2 Retail BR.
If that doesn't help, you should go to Claro and ask them to either help you enable it or change the SIM card with a 4g enabled one.

The problem was the SIM card.
Got a new one and now I have acces to the 4G network.
Now the problem is that I can't connect on 4G.
I have put all APNs existent on my carrier and it didn't work...

Look, just in case... have you tried to flash a retail ROM in your phone?

I bought my phone from VIVO and I tried 4G and it wouldn´t work (ICS 4.0.4). Later, I flashed ICS 4.0.4 RETAIL and tried diferent carrier chips and the 4G was running fine on CLARO.


Also, if you can try this on your phone, downgrade from JB to ICS and try your 4G network (and remember that 4G technology is extremely new here in Brazil and reminds when 3G came - the services were bad because of poor infrastructure).

Let´s wait and see.

Abraço! kkk

Hi i updated mine with reatil but now i have a lot of acess "Acesso Restrito Alterado" problem when i go from "e " to h+...
I tryed to change *#*#4636#*#* com wcdma only to gsm/cdma auto, but no sucess, Where do I find the VIVO modem to flash? only the mondem

I'll try to explain to you.
To get the modem you need to download the full vivo 4.0.4 Rom and extract the modem_signed and fsg_signed.
Then all you have to do is flash both on your phone and erase the modemst1 and modemst2 partitions.

That's everything I can explain walking and typing on the street.

4g is active in Rio? I thought it was only being tested in some areas like buzios or angra..

What's the max speed you've gotten?

 

[liquelt]

I've attached what is happening with me...
I live in a area that has lte signal but the network just don't work. It connects but it doesn't change informations with the network.
Here in Rio the network is still in test on Claro... but I can tell Oi has the best signal by far in Rio.
I don't know how or when Claro will finish implementing this technology here, all I know is that they are moving fast. They have until April 31st, so let's see...

Man, I flashed Stock 4.0.4 Retail, fully. I didn´t mix modem or FSG files. It´s totally stock. Our phones are supposed to detect the Lte automatically and without any configuration, since the SIMcard download all the config needed when the phone starts. (At least that happens to mine.)
