[Q] This device in germany

Dear all,
i got this phone from a friend (S3 from Verizon, SCH -I535) but I'm leaving in Germany, i thougt it would be enough to Flash a custom Rom to get rid of the sim lock but it Looks like that there are morre technical issues that i know :crying:
So what i find out is that it uses CDMA 1x/EVDO Rev A. instead of GSM/UMTS and that the LTE band is ankother one.
On the other Hand i read about the jellywiz gsm Rom for that device, the outcome is that i'm very confused right now.
My question, is there a Software based way (custo Rom, kernel, modem etc) to make this device working in Germany with a german carrier sim Card?
thnx in advanced

Update the phone to the latest update and you can use it without having to root it

and it will work in Germany using german sim on gsm/umts and LTE??

1: Are you on the MF1 update?
2: If yes, go to Network mode and select GSM
3: wait for a couple of mins
4: go the APN setting and enter all your APN details.
You should be set

[Q] 404 to 4.2 upgrade

I trying to find a working firmware for verizon s3 sch-i535 I have it unlocked using odin. T-Mobile [who I want to use]
confirmed my phone is unlocked but they can't connect because my firmware needs to be updated from 404. I went and tried
to get update but run into webpage not found Does anyone have direct download for updates.
Every site I go to is a big runaround. It can't be that complicated can it? Hope I get some help here. Thanks.

T-Mobile = GSM
"This is not a GSM device, it will not work on any GSM network worldwide."
You can try whatever you want, the phone will only support carriers using CDMA
You can find every firmware that has been officially released at SamMobile

Thankyou. For getting back.I still want to upgrade the firmware 404 is old

If you already checked SamMobile you saw that you can choose between:
4.1.2
4.3
4.4.2
There is no reason for not using KitKat 4.4.2
Once installed you can flash latest TWRP using ODIN and then flash SuperSU (For root access) using TWRP. Rott access is highly suggested to remove the bunch of bloatware coming with Samsung's firmware and for grant sd card r/w access for all your apps.

I knew that my phone is unlocked so I did a lot of reading and found that if I go into service mode and enable hidden menus that I could
go into mobile networks then choose other networks. There it is GSM! now the next window is a menu to choose band or all bands.
now I took the battery out and installed the T-Mobile Sim powered back up and get a message: Welcome to T-Mobile. Tried making a call
IT WORKS! TEXT ok Internet ok. This was all done while still running stock 404 firmware. I'm no andriod genius and don;t know why all
the posts I've read saying it can;t be done. All I did was use the advise you guys gave did the proper download to unlock and root.
This issue is resolved. Thank you!

[Q] Lost 4G after flashing another Stock

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.

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!

EE / Three UK VoLTE

Hi.
I have a EU Xzp single sim version. I flashed 3UK firmware but don't get band 20 access or volte. Anyone here flashed onto 3uk or EE and get volte? Anyone getting volte with carrier branded device in UK?

Sony Xperia XZ Premium
How did you flash your Xperia XZ Premium, i want to flash mine but flashtool is still not compatible, i am able to download the Rom but the flashtool does not recognize the phone when its time to flash. Please help.

You use the new flash tool:
https://forum.xda-developers.com/crossdevice-dev/sony/progress-newflasher-xperia-command-line-t3619426

Op, can you check what configuration your phone has loaded? To do this type this in dialer *#*#7378423#*#* then "Service Info" then "Software info". there should be row called Current modem Config: What does it read?
From the XZ Premium available modem configurations i can see following UK stuff available.
amss_fsg_maple_ee_ims_tar
amss_fsg_maple_hutch_uk_tar
amss_fsg_maple_hutch_uk_volte_vowifi_tar
amss_fsg_maple_telefonica_uk_ims_tar
amss_fsg_maple_telefonica_uk_tar
amss_fsg_maple_virgin_uk_tar
amss_fsg_maple_vodafone_uk_tar
amss_fsg_maple_vodafone_uk_volte_vowifi_tar
For the 3UK to work from phone side, you probably need amss_fsg_maple_hutch_uk_volte_vowifi_tar loaded in current modem config.
Do you have volte calls option available under Mobile network settings?
If everything there, but not working still then need to get feedback from 3UK if they need to switch it on for XZ Premium

hi with EE firmware there is current modem config there is: amss_fsg_maple_ee_ims_tar.mbn and EE Wifi Calling and EE VoLTE works
hi with 3UK firmware- the correct modem config is there-> but no Band 20, No VoLTE (and no Wifi Calling- looking at 3UK website -> even the 3UK XZP doesn't have Wifi calling support).
I note the EE current firmware security update is from June'17, 3UK latest firmware is April'17.
Maybe things will improve when 3 UK update their firmware
A big downside of XZP seems to be you can't lock onto a specific band... (you can fix LTE but not the band)

If the correct region firmware is flashed and correct config loaded then volte should be good to go from phone side.
Operator can still limit volte per device model or firmware version.
Comparing the April firmware and June, there are no changes in modem config files.
But there is hope that new build is the qualifying factor for 3UK.
O2 UK has volte and vowifi active with the June update also
LTE band locking will be available when good root support arrives.
PS. If you feel like experimenting then you can take the latest EE firmware and switch out the oem.sin from 3UK firmware and flash it.
This should give you newest base and 3uk oem config.

I have just flashed the 3 firmware. I can confirm that I am not getting band 20 or volte.
The option to turn it on is not in settings either.
Current modem config:
/system/etc/customization/modem/amss_fsg_maple_hutch_uk_tar
Hopefully the June update will fix it.
Edit: I can't test adding the three oem bit into the ee firmware as I am going away now and can't flash my phone. But will try and test when I get back if no one has (or the newer firmware is available) by then

In that case it is loading the wrong modem.
The modem that is needed is in the folder but not loaded.
amss_fsg_maple_hutch_uk_volte_vowifi_tar.mbn
Whereas the one that is loaded is amss_fsg_maple_hutch_uk_tar.mbn

if you could alter files in oem.sin then this could be changed.
Do we have a method to repack .sin files? I know how to "unsin" and how to extract .ext4 but repacking is unknown to me.
Also it is possible to select the configuration manually via app. Might not work with non-rooted devices.
Check the tutorial here https://forum.xda-developers.com/crossdevice-dev/sony/enabling-volte-xperia-z2-xperia-z3-t3438505
root, build.prop changes and shortcutmaker is needed.
Also maybe the 3uk june update will change which configuration is loaded will check when it drops.

Anybody managed to connect to band 20 on EE with the latest firmware update?

Not sure if I've connected or not with the latest update, but since then I no longer see 4G+ (which is the norm for other EE phones, but for some reason I had it on the XZ Premium until now).
It is still using CA and VoLTE is still working, so I assume band 20 is still usable.

Cellmapper https://play.google.com/store/apps/details?id=cellmapper.net.cellmapper will show you which band you are connected to.
My Sonyss show 4G+ when there is Carrier Aggregation in use. Should see LTE-A in Cellmapper when that is the case.

Sony XZ Premium fingerprint enable? Help

I am getting my Sony "U.S" Version just because of its warranty, is there a way i can Enable the fingerprint. Please help

currently all you could do is flash the International firmware. I haven't really looked into anything though personally. I'm not sure how they disabled it, maybe changing a 0 to 1 somewhere but I doubt it.

Yes I got the US version from Amazon and just flashed the CE1 firmware and fingerprint works after flashing that firmware

It doesn't have US warranty, probably you have to send it back to UK. Personally I don't care about warranties, never had to use for any of my many phones until now partly because don't keep the phone that long. The other advantage buying from Amazon US is ease of return in case you don't like the phone. If you played with it before and 100% sure you like the phone and will definitely keeping it, then yeah better to buy from clove and save the extra $150 or change.

I used the newflasher tool in the below link. Personally this is my first Xperia device in a long time and haven't used the Xperia flashing tools before.
https://forum.xda-developers.com/showthread.php?t=3619426
1. Make sure you have the right drivers installed. I installed Xperia companion tool since someone mentioned that should install all the drivers. I also installed the flash tool and fastboot drivers from Xperia flash tool since I had issues putting my phone in flash mode. If you are using Windows 10 you have disable verify driver signing in boot before installing the flash tool drivers.
2. Download the firmware of your choice, I chose CE1 (Central Europe) firmware over other Asian firmware.
3. Then follow the instructions in the thread to flash.
Main issue I had was putting my phone in flash mode. But apparently flash mode doesn't have any screen like recovery etc. You just have to turn off your phone then while holding the volume button down connect your phone via USB. That should put in flash mode even though you don't get any screen to say it's in flash mode.
Once I put in flash mode everything went fine by following instructions in the thread.

Thanks,
So when you downloaded the files with XperiFirm and used NewFlasher did you delete any of the files or just drop newflasher into the created directory and flashed everything.

Just dropped all newflasher files into the created firmware directory and just ran the newflasher application from that directory. It flashed everything in there.
I know the thread says if you want you can remove specific things from the firmware directory if you don't want to flash certain things. But I didn't see any reason to do that and I never care about wiping my device since all my info is backed up in the cloud and takes around 30 minutes to restore and be up and running again. Just to be safe I flashed everything so that it doesn't screw up anything. I haven't used the Xperia flash tools before so kept it simple.

I'm pretty sure it's the US model because the fingerprint sensor is disable.

there is no VOLTE on this phone, no menu options for advanced calling like wifi calling either.

Must be an Branding/Software issue i guess.
On the unbranded EU version, both is available.

I bought mine from the UK (not sure if it is the same as the unbranded EU version you mention) and when I look for those same settings they do not exist.

Could be that the settings are not available unless your carrier/plan supports them. Pretty sure anyone slipping a T Mobile sim in has those services.
