Hello guys.
I have a xperia Z3 from VIVO and flashed a rom from OI, everything went well on flashing the rom but after it finished i noticed that i lost my 4G. When i search for network there have a TIM BRASIL LTE but it won't let me register on it.
Do anyone know how to solve that?
Thanks!

Lito, do you think that would help?
Because the problem is that I am not able to register to the LTE network, it's not related to the ability of using internet.
Actually, this is exactly what happens, after i flash the firmware i have 4G but after a few minutes (Between 5 and 10 minutes) i completelly lose connection to the LTE network, even if it's available in the networks list.

just test firmware of another region
(UK firmware for example)

Maybe if you explained a bit better that would?
Like mentioned before this post, try to flash only the baseband from another region, hopefully that will solve it.

Lito, thanks for the sugestion, i flashed the baseband for the Customized PT and after flash i got the 4G signal for about 30 minutes, but when i rebooted the phone, i completelly lost 4G again, and now in the network lists there is no LTE from TIM. Could it be because i installed an european baseband on a mobile here in brazil?
Thanks agian.

thats weird... are you sure you have the correct APN settings inputted? Also, i would assume youve tried flashing the VIVO's baseband or any other USA roms?
Try the following if you have already done all those: go to dial pad and input *#*#4636#*#* > phone info > menu top right > select radio band > try Australia or USA or what ever pops up > scroll down and make sure LTE/GSM auto is selected or try out the other ones > scroll back up and hit the "run ping test"
if all these doesnt work, i would advise you to go back to the original rom.
just curious, which model number is your Z3?

Lito, now i will complicate a little bit more then. First, the model number of my mobile is D6646 from Brazil with DTV.
Also, i tried to flash the Vivo Baseband and it was worse, i did not install any baseband from USA, just from Portugal.
I tried that on the keyboard, but when i chose USA band i just can't even register on any TIM network.
Also, i tried to flash the original rom, but i can't flash any other firmware apart from Oi. I get a blank error line on flashtool for every other rom i tried to install, so it's even worse
Feel the challenge.
Thanks again for all your help.
flash back to the original ROM if you can, also, how did you flash to the new rom? through recovery or Flashtool? if you see a blank space or what ever, you might not have the correct drivers installed on your computer, especially if youre running Windows 8.
that being said, i dont see D6646 in Xperifirm, i cant tell you what to flash and what not to flash. Without that, i wouldnt advise you to flash anything but the original rom that it came with, you dont want to soft/hard brick the device.

Lito, I tryied to flash the original room, I am using XperiaFirm to download the firmware and flashtool to flash. I can flash the Oi room, but i can't flash the vivo BR, the Claro Argentina, or the Customized PT, all of them results in a blank error, it's not drivers problems, since i can install the Oi firmware and also i disabled the signature on windows in order to install.
Anyway, i solved the problem in order to show another problem. Here is the situation:
I created another APN to use when i don't want to use internet because even with data package disabled my mobile send data to the carrier that charges me, when i deleted that APN the 4G worked perfectly, but now my carrier is charging me the data . Any idea how to block this data comsumption?
Thanks again.

that is extremely weird, never had such issues with any of my android phones. make sure data roaming is not on, the carrier shouldnt be able to charge you if you disabled data
Also, make sure the FTF files youve made with xperifirm and flashtool are correct, like not including the TA files etc..., i would advise you redownload those FTF files and try again, also make sure you have the latest flashtool available.
at this point, you are probably better seeking for a developer or someone who can read codes, make a logcat and see if the flashtool thread is available and ask there. Aside from the FTF files, you are better off asking the carrier why they are still able to charge you in such way. Sorry man, this is as far I can aid you in this matter. GL bud!
HI, i recently unlock my mobile (globe) Galaxy S6-G920f (dual sim) via a payed unlock service from a certain website. It was unlocked successfully and new network appear shortly, but without mobile data it means i cant receive an internet signal only call or text. I have notice this message in APN settings in which i cant add new APN setup "Unable to view the access point name settings. Access is restricted for the current user profile".
If anyone experience this feel free to share it before i flash any custom roms or root it, thanks.
You can:
1. Go to recovery mode and wipe cache.
2. Try enabling screen lock with your chosen security method.
3. Go to Gobe and get settings and enter them manually.
4. Do full reset.
5. Flash stock 5.1.1 ROM via odin.
Hi,
I am sorry that I post this message in the wrong place, I believe it belongs to this thread
I have just return from US and I got a LG Leon from MetroPCS to sty connected while there. Now that I am back I unlocked the phone via unlock app. My surprise came when I put me Spanish SIM card (Jazztel) and the phone only gets 2g connection. I have been searching the net and I found some threads on the topic but I can not make any of them work on my phone. First I tried changing the radio to Europe mode through *#*#4636#*#*, and I enter the test page but when I click the phone info button I get a message that states that I can not run that application on this device. I thought it was because I wasn't root so I rooted it. But before I could root I had to downgrade by flashing an older firmware. No way, I get the same message. I tried the hidden menu to see if I could find an entry to change the radio mode, or any type of LTE configuration. Hidden menu on my phone though 277634#*#. I also tried the anycut option, but I do not get any facility called LTE configuration or similar.
I am desperate and I do not know how to proceed. Any help is welcome
Thanks in advance
I purchased a brand new LG G Flex 2 and It dawned on me that it was a Sprint variant LS996, rooted and unlocked. I do not live in the US and the phone is working fine with my local carrier, except that there is no tethering option. It currently has Android 5.1.1 installed and software version is ZV6. Since the phone is rooted, OTA updates download but fail during installation.
Now, what I want to achieve is to update the phone to the latest software version and also retain the carrier unlock. I would be thankful if someone can point me in the right direction. It would also be nice if I am able to make a full backup of my system in its current state so I can revert if things don't well.
Thanks
I am in the same situation with my LG g flex 2, there is no hotspot option.
Follow my back to stock guide with stock images on general section. That should help you to go unroot pretty easy and then ota update. Read through that forum there are several suggestions you may apply too.

Thanks for your reply. From what I understand, I have to flash stock ZV6, OTA update to ZV9, and then flash rooted ZV9. Will I lose the SIM unlock in the process? I have seen some people on another forum claim that they went through this process without losing the SIM unlock. On an another note, I managed to enable tethering by changing network mode to Lab in the LTE settings hidden menu. This also disabled the annoying Hands Free Activation screen. However, the Wi-Fi tethering is limited to 1 user. I tried the suggestion of changing SPR to GLOBAL in build.prop, but I couldn't save the file if I added anymore than three characters in place of SPR. I also tried adding dun to APN type in the LTE settings menu, but found out that APN type is not editable.

You wont lose sim unlock...
Just do the process...
I also deleted some of the folders in carrier and just left the apps and I really dont remember which other cause I sold my phone.
