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.

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!

Docomo SC-01F (SIM Free) unlocked "Mobile Network not available"

Hello Guys, at first thank for all people for this forum, helpe us a lot. First time posting here.
I bought a Docomo Galaxy Note 3 SC-01F, then I wnet to Docomo Shop to unlock the SIM, the unlock worked well. I put by Odin the International rom to use the phone in my language and used in Brazil with the local SIM operator, all things worked well. So now I returned to Japan, and took a AU KDDI SIM in AU shop. The seller put the SIM, and configured the data transfer(OK) but the call number failed(Mobile Network not Available), he tried at least 3 hour. So I went to my house and tried by odin put the original docomo firmware, but the result is the same, the network data is ok, but call function return the same error. In the place of antena signal show a circle look like prohibit.
I tried other firmwares more recents provided buy this site, no result.
The IMEI is the same in the back of device.
Put the Access Point data provided by AU seller.
Tried to search the network, just show docomo and softbank, sometimes show the AU, but I try to connect give failed.
Try to automatic, failed.
I dont know what can I do more. Please anyone have some idea?
The problem is I cant connect to AU KDDI provider to make calls "Mobile Network NOT Available".

The company name is AU KDDI of Japan. When I bought the SIM, the seller gave to me these data to configure after I flash rom by odin. Because the seller did not got success in international ROM.
I did a flash by Odin the original firmware from the original company(Docomo) and put the data provided by the seller.

no problem, we are here to help.
im sure the problem is the phone, since sims, networks andphones are very different the all have some conectivity issue when you unlock it, my best advice is go to the and see if they can help you if not then try rooting it and flashing a custom rom for the phone and im sure that will help you most of the time

Well after the root you must check if device is bootloader unlock if so look for a method to unlock it, then flasha custom recovery and flash a custom rom.
Well is basically a firmware with a bucnh of customization, tweaks and mods, it also lets you use your phone software as yours not as the company whants you to use it. There you can use customs roms from other phones that are compatible( ported roms) and try them it can include fixes or be more compatible with the network

I understood and studying about it.
The first step i got it: ROOT THE ANDROID 5.0
I used the method below, and checked if success in "root checker" and other app, its OK.

The second step I cant do it: Bootloader check
The guides in internet say this: *#*#7378423#*#*, but in my phone I cant use the dial, show "Mobile Network Not Available"
Any other Idea or tutorial to follow? I saw other methods but cant understand.
My objective is: Try to put the firmware of my sim card owner(AU KDDI), to see if I can use the Dial.

That's mean I can downgrade my firmware to any D6603 ROM even my currant Customization version is: 1289-4144 (Customized DE). There is not issue with sim card if I use other firmware like .77 or .93 with different customization number 1288-5031 as any example. Right?

That's what Robogo1982 means by any, yes.
For example my phone came with RU firmware. But I have flashed UK, German and Netherlands unbranded firmwares without a problem and SIM stays unlocked.
The only differences between them are the apps that come pre-installed

Should be fine to downgrade straight but make sure to wipe data as it won't boot with Marshmallow data on the phone.
Flash tool has an option for this youll see it. Just tick where it says wipe: apps log and user data
Obviously bear in mind this wipes everything so back up everything before hand.
You can try without wiping data but this causes a boot loop for me.
Hit thanks if we helped. Button is right under our comments

So:
Even if you flash branded firmware like T-Mobile it will stay unlocked and any sim will work. So this won't change anything there don't worry.
I mean you will lose all your apps and settings etc.
Not sure about photos so copy them across to your computer just in case. You can just make a backup with PC companion.
PC companion will detect updates based on which country firmware is on your phone. If you flash Russia you will get the updates for Russian version and when they are available to Russia.
If German then updates will be German and when Germany gets them etc
Makes sense?
So best is to flash your country version and then you get updates as they become available to your country,
but you can use any country version you want and get updates when that country gets them.

Need Solutions For Sony Xperia XZ SOV34 With No Service Carrier

Hi everybody,
I still have a problem with my carrier signal.
1. Sony XZ SOV34 has SIM unlocked
2. Already unlocked bootloader
3. Using Global ROM and already using ExistenZ Oreo
The problem that makes me confused is imei and baseband, there is no problem, but the sim carrier cannot register.
From this problem what should I do?

Hello can you check your apn settings for your operator? If they are all setup correctly try selecting network manually.
Note: You need to search your own mobile operator's apn settings I can't really help with that.

Fido keys doesn't matter for network connectivity. Since you can't setup APN thats the reason it is not connecting. Are you sure that you are not running dual sim version of Xperia XZ? Can you also try tp flash stock rom without exitenz mods? To see if it changes anything.

Just follow one of these Guides...
If U have Unlock Code for Network:
If not try this. It's not easy but works:
I can't post links here. PM me if you still need help
If your baseband and IMEI has gone just flash the 39.0.C.0.282 AU either with flashtool. Better option is xflasher

Installing global rom to Xperia 5 AU

Is this will be ok?, because Xperia 5 have 128GB and AU version have 64GB.
anyone have tried it?

Please don't flash if yours is a different model as it may break your phone. Only of the same specs model.

when I hear the word AU,I think that you are from indonesia tercinta merdekalah katanya

Huh. Please don't attempt to do it. My Xperia 5 bricked after doing it. And since the phone had some USB issues, getting into flash mode again was very difficult and consumed around 2 hours fiddling with the volume keys. Because the red light just blinks every 2 seconds or so. No green light after connecting USB while pressing volume down. Finally when I got it in flash mode, flashed the SOV41 AU version which brought the device back to life.

No harm in trying it (in my experience). Just give it a try and if it (bricks) doesn't boot, force shut it down, put it in flash mode, and reflash the original ROM with NewFlasher, (Don't use FlashTool) and boom, back to working again.
Edit: why have I just replied to an almost 3 year old thread at 00:53 in the morning... Good damn it lol.

ROMs that I tried but failed :
SO-01M NTT DOCOMO JP - Signature error, not even flashed.
J8210 Customized UK - Bricked
901SO SoftBank JP - Bricked
All I was trying for to use 4G network as Jio Sim works only in 4G. Even though a toggle was available in the AU version to enable 4G, it didn't worked. It can't even connect to network by manually selecting. And 4636 method don't work.

Replace AU oem files with attached files. Flash with new flasher. Probably no AU messaging app after flash. so you need to install either google messages or use attached au original message app apk.

Great. It worked. Also bloatware removed. More like a Global ROM with VoLTE.

i tried to flash global firmwares on my xperia 5ii softbank, but there is not network. Tried flashing AOSP roms, still no network. Anyway to get out of this japanese rom. I tried replacing the OEM files, still no luck.
