[Q] TIM Brasil signal on CM11

Hi,
I can not get signal on a TIM chip on 07/20 CM11.
I tried a lot of different baseband and my VIVO chip works correctly in that ROM.
Can anyone help me with this TIM chip?
I will use my phone as a modem, tethering internet to my notebook.
Thx all.
Today I have tried a new version of CM11, from 07/25/2014, and can not get my SIM card to work with my Defy+.
When in another phone, the SIM card works and I can get signal from TIM Brasil.
Can anyone help me? I need my card working until tomorow night.
Thx.
Today I tried all the basebands that I could to make my SIM card to work.
There is a way to check some log files or debug info in order to find some clue about the problem?
Thx.
Download defy baseband switcher 4.0 (blue icon), there's a Brazil TIM baseband
My problem was not an incorrect baseband.
My phone was locked by my carrier and i had to revert to stock ROM to unlock it.
After that, CM11 started to work with my new SIM card only when I did a factory restore of my phone and start CM11 from scratch. With my older data, CM11 yet was locking my new card.
Thanks.

Network Problem

Hello Guys
My Friend bought SGS6 Edge+ (G928C) a used one
the phone works perfect it has one problem only, the phone doesn't get mobile network
the previous owner said the before he updated it the phone was working great, but after the android 6 update the network didn't work anymore
when i took a look at the software information I noticed something strange
The Baseband version: G928FXXU2BPB7
Build Number: MMB29K.G928CXXU2PBP8
Now i'm not expert on the subject but as far as i now the baseband & build number should be aligned, i mean the bb is G928F and the build number is: G928C
could this mismatch cause the noted problem ?
will a full wipe with the correct corresponding ROM fix the problem ?
thanks for your help, it's greatly appreciated

Galaxy S3 i9300 - Not registered on network

Hi at all! I'm new on this forum, so I hope I didn't break any rule. Anyway, I'm trying to recover a friend's phone, a Samsung Galaxy S3 (i9300) International Version.
He said he installed a rom called "Android Revolution HD", which appears to be an improved version of the stock rom. Anyway, now the phone does not register on the network.
The IMEI in the settings menu is correct, also the signal appears to be ok, but when I try to select a network, the phone does not register.
So, I tried almost all the solutions I have found on this site, from trying a bunch of different modems, to installing the whole stock ROM (Android 4.3).
But none of these worked. So, there is a real solution I can try?
Thanks in advance!

I have the same problem for months now i have tried a lot of solution but nothing works. i am hoping a senior member can help fix this issue. And just incase some has a viable solution, they should kindly help out. :fingers-crossed:
What I think is you've updated it from 4.1.2 without any EFS backup. Well I had been through the same situation and couldn't find I single thing. In the end I had to get my S3 repaired from a local shop. I think you should go too.

Dialer problem!

Hey guys! I got my note 4 today. It is used.
It came at 4.4.4 android version and rooted. So i installed TWRP and flashed BLISS Rom.
But right after i dial any number, i got "call ended", i cant receive calls and sms too.
I already tried another SIM card, but the problem persist.
I also updated the bootloader and the modem to the 6.0.1 version from the ditto note 5 rom topic.
What else can I do to make it work ?
Did i got and defective phone ?
Is the SIM card you are using only works under 4G area? Or does it support 2G/GSM as well?
Try reinstalling the stock firmware and see if that helps. But don't root it this time.
Yes, it supports 4g. And i already tried the stock rom, but with no results... What can i do ? D:
APN settings correct for your carrier?

mobile network is unavailable after custom ROM install.

Hello Guys,
I bought an S4 and I discovered that I was scammed (it was the sprint version and not the GT-I9500 as it was indicated on my about phone tab). It comes with 4.4.2 and everything was working fine (the only things that bugs me was that I was unable to receive updates). Recently I encountered some little issues so I decided to install a new ROM. I tried the Vanir and Commotio ROM and for a moment I was super satisfied (it was an amazing experience). However after putting back my SIM card, each time I try to deal a call, I got the error "mobile network is unavailable". I thought it was an issue from the ROM I used so I tested the LineageOS and same issue. Finally I tested the STOCK ROM Lollipop and the same issue again except this time the WiFi does not work. Now my phone is completely useless, so can anyone help please ?
PS: When I go to settings->about->status, everything about the SIM info(network, my phone number,...) is set to unknown. the IMEI is intact (non null). IMEISV is 00.
