hello everyone,
a friend has recently bought a Sony xperia z2 for me from china and the model i got is the china unicom model (l50u)
the phone is censored on the stock rom it has, cannot use any applications that aren't Chinese government approved i guess (no google play, gmail, etc and you can only download Chinese apps through sony select which is in Chinese and cannot be changed)
this phone model is physically different than the rest of the sony xperia z2 (2.2mm taller, no mic holes, different slot locations )
anyway i unlocked the bootloader (before i really knew what it means, i wanted to root the phone) and then i flashed it with some other official roms using flashtool
when the phone runs on a different rom, everything works great except for the sim not working (the phone is supposedly simfree as it recognizes my not-china-unicom sim) and when its on the stock rom only the sim works and the phone is pretty much useless to me but a weird camera
before i started noobing around the device i updated its firmware through Sony's pc program which gave me the files to create the ftf file from and some more TA files in which one of the is called simlock.ta
i tried installing Emma and see if the phone is registered as simlocked but i couldn't get it to work (it seem like it is no longer for non-sony employees people)
so i ask you. is there any way for me to use this phone with a different official rom and make the sim work with it? is there anything i should know about? any help is appriciated as im new to this community (which i enjoyed lurking around in the past) and to this area in android devices (as i was quite pleased with the Os as is on previous devices)
thank you for your time, and keep being a great community
any help is appreciated

today i solved this problem with the help of Olberd and Chesterr
First i flashed to Generic Euro Rom from this thread
using Flashtool
then i rooted the phone using EasyRoot V8(check if your device works with it in it's current state)
then i installed SuperSU
then i installed Nut's Dual Recovery(locked) [you can probably check for a newer version and or change to an unlocked bootloader version]
then i flashed the radio drivers:
for the L50t (given to me by Olberd): Here
for the L50u (made by me using Olberd's files as a base*): Here
(put the driver zip on the root folder of the phone, restart and press the volume down button when the phone vibrates, untill the blue led lights, navigate to "flash zip.." and choose the driver zip)
now both the phone and the sim work, so far everything works fine ill update if there are any issues with the phone.
thanks everyone for your time and help!
*: take any of these 2 zip files and put your current original firmware's radio drivers - i used a root browser on the original firmware to get the radio drivers (copied them to a folder i can access normally on the phone) [search for the files you see in the zip].
NOTE : Use the drivers suitable for your phone, although they work on both phones they cause weird shutting down issues when installed on the wrong phone
Update : i checked all the links and wrote notes about EasyRoot , Nut's Duel Recovery and how to make the flashable zip file . i'm sorry but i cannot help with newer problems because i dont have this phone anymore as i posted before. i got some PMs and emails from sony support forum and im redirecting people here.
Update 2: apparently the google drive link became locked due to some google's change, so i updated the link so its downloadable again.

If your z2 is 2.2mm taller then it is the L50t China Mobile Model, The L50t uses TD LTE for 4G, the 3G is locked to China Mobile, but roaming with China Mobile Sim card is fine, it means you can only use China Mobile Sim card if you travel outside China. You can try to buy a unlock code, but only 3G will work, 4G LTE will never work unless you are in China.

this is the l50u model of china unicom and im currently in the middle east and the my sim works on the device, i dont think you read through the whole thing :S

Emma actually works. You need to copy the customization file when you initially extracted the zip, into the installation directory.
It was something that I actually missed too and there is a guide on Sony which tells you that. Once you copy that, Emma will work.

Have you found an uncensored firmware which works on the L50U yet?
BTW, its not the SIM that is disabled, its the whole GSM/UMTS/LTE radio functionality that gets disabled. My phone keeps telling me its in Airplane mode when its not. Also its confused about where the covers are for SIM/charger/microSD and keeps telling me I've left one open when I haven't.
Does anyone have the blob_fs files from C:\Program Files (x86)\Sony Mobile\Update Service\db\13740270\blob_fs starting FILE_ which you would get if you upgraded a real model D6503 to 17.1.1.A.0.402 as I'd like to try rebuilding the FTF but specifying model L50U in the build process to see if that would work?
If you have the blob_fs files for building the Generic FTF, then please post them here?
TIA

yea, the sim is unlocked by all means but it wont work on any other rom (i flashed a few : RU and UK unbranded ) both work fine except the SIM. (as far as i noticed everything else worked fine)
i posted on sony's support forum and got no help really.
also posted Here but nobody could help me
i got the "official" rom for l50u from when i updated it, i just have really bad upload rate and i saw no interest in it - i can upload it for you but it may take some time.(i also still has the FILEs )
i also tried flashing combination of roms (excluding things on the list) but that didn't work, and the new easy easy root didn't work on the l50u as well
i figured the only thing i could do is customize a rom like CyanogenMod using this? (their link is broken but if you change "other" to "copylefts" it works)
but i currently don't have the knowledge and more importantly the time and patience : |
a friend also took it to an official sony retailer but he couldn't do anything about it and also said the warranty is voided as i unlocked the boot loader before there was a way to back up the drm keys)
so tell me what you think and need from me and ill upload it for you.
thanks for your time and have a great weekend.
I am having the same issue with l50t phone, I was unable to get google apps to work on the china rom, and reading the forms they say it needed to be rooted to make changes to the host file.
I use doomlords "Z2_DooMLoRD_AdvStkKernel_FW-438-v05" after unlocking the bootloader, but that stopped my wifi from working. Mobile network still worked though.
Then I tried using cyanogenmod but had no service.
Finally I flashed it using "Canada - unbranded - 1281-9709" (I didn't back up the original) and still no service.
I have checked the IMEI number and it is still there.
Have you or anyone out there have an answer? Please and thank you

Unfortunately, I need help from those millions of people with a standard D6503 model, not us few who have the L50u and L50t models.
*YOU* reading this with a D6503 model - Please can you go to re-upgrade your working 17.1.1.A.0.402 firmware (no need to go ahead with the upgrade in reality) and send us the blob_fs files from C:\Program Files (x86)\Sony Mobile\Update Service\db ?
I'd really like to know if Flashtool can decrypt your D6503 blob_fs files and make a working L50u FTF from them.
Thanks.
Maybe someone can help me get going to get the SIM working.
What I've found is that the radio is turned off.
Dialed *#*#4636#*#*, but am unable to turn on the radio or select radio band (get "set [usa band] unsuccessful")
Also could not select preferred network type. I also can't change this under network mode in mobile network settings.
Please help me to figure how I can get network service.

Hi Pitzmans, how did you solve it?
Have you got the radio to work with a non-Chinese flash? or have you found a way to unlock the Chinese OS so we can get apps from Google Play store?
TIA Banjo

well yes, you can read the issue i had in the quote on the first post.
when i flashed to other roms Google services worked (search, gmail, play store and i guess the rest too but i don't use them) but the sim did not.
so this method flashes a stock rom and installs the radios drivers basically.
Help needed !

Hi, I have the same problem as you. I follow your instructions to flash but it says "drivers need to be installed". See attached picture. I am using windows 8.1.

you need to install drivers for your device :
http://forum.xda-developers.com/showthread.php?t=2635830
install the fastboot and flashtool drivers along with the z2 drivers
i will post the original l50u radio drivers tommorow or later today so if you got the l50u model you should wait.

Hi. I manage to install and flash successfully. But now I have another problem. My phone now is unable to have any signals. I am using China UniCom SIM card. I guess I need the L50U radio drivers files. And also instructions on how to flash the radio drivers files. Thanks.

this is quite unrelated, it seem like this is a windows 8 issue, try this solution :

check the first post of the thread
I want to try and enable VoLTE and wifi calling on Three uk on a J8110 as the signal is marginal in the two locations I'd like to use the phone from and coming from a samsung S7, I can see that the phones a few db's down on signal to start off with, so I really need the VoLTE or wifi to make the phone useful to me.
Now under this thread:
https://forum.xda-developers.com/xperia-1/help/google-dialer-volte-t3975441
They say they managed to get VoLTE going using root.
1. Root
2. File Manager with root support
3. Go to /oem/modem-config
4. Delete "anysim" folder
5. Rename "S9033.1" to "anysim"
6. Go here " https://forum.xda-developers.com/showpost.php?p=80231731&postcount=395" and download "VoEnabler.zip" From the Google Drive link
7. Put "VoEnabler.zip" onto your device and install via Magisk and reboot.
8. You should now be able to use VoLTE and VoWiFi.

So my three questions are;
Is this likely to work? e.g allow VoLTE and maybe wifi calling
Will it break safetynet by rooting the phone? (as I use internet banking)
Will it break anything else like DRM keys.
I see there appears to be multiple rooting options for Android these days if I can do the above is there a particular rooting method thats more likely to preserve the safetynet compatibility?
And maybe the DRM keys.
As I'm only interested in Enabling VoLTE and maybe wifi calling.
As an aside to that I see in this thread, https://forum.xda-developers.com/xperia-1/help/enable-volte-ee-uk-t3958112/page3
That some people on EE have got VoLTE working without anything special is this just because EE is just a network sl*t and just allow anyone on there system?

If you're on the Customized UK firmware, VoLTE should work by default.
I have the Customized UK firmware downloaded and I just checked, and it does include the required MBN file for VoLTE on H3G in UK. I am on the Dual SIM J9110 however, but I reckon it should be the same on the single SIM J8110 as well.
Yes, rooting will break SafetyNet on the Xperia 1. Magisk Hide works on some banking apps, but some of still fail to work once the bootloader is unlocked.
You will lose DRM keys, but from what I've heard, they are restored if you re-lock the bootloader.

Yeah can confirm its not working on three uk, as other have already said in other threads..
*#*#4636#*#* > Phone info > VoLTE provisioned is grayed out.
Also cannot access three on the 800mhz LTE band 20
TBH three when I spoke to them just wiped there hands of the issue and said we don't sell the phone so speak to sony.
So much for industry standards.

You could try the method that enables the VoLTE toggle. In theory it should work with just that because the required files for IMS registration to work are already included in the modem for the Xperia 1.
why not just flashing another FW before losing DRM keys while rooting
we had a user he used a non European Market Xperia 1
no option for voLTE or Wificalling
after flashing the European FW everything was working just fine for him without any kind of rooting
I have flashed South East Asian (SEA) on mine and it has option for the VoLTE in the Network & internet > Mobile Network
It has Enable VoLTE and it can be toggled on and off. (although we don't have the VoLTE here )
If they are already providing VoLTE. Flash SEA firmware.
Ask? Is it possible to change the firmware of my carrier and put the global firmware on it without unlocking the bootloader? My cell phone is a nokia 5.4 and it comes with operator firmware (CLARO-TELMEX-TELCEL), Although altering the SIMCARD tray, the cell phone recognizes the two simcards of different operators, but many functions that are usually in the global version to manage each sim, are disabled. Again, it is possible to remove the firmware from the carrier and put the Global firmware on my cell phone.
It´s Posible? please!!
Hi @Scdo-117, I think it can be attempted via anybody offering Nokia remote flashing services.
The regional differences are pulled by the SKUID and the firmware remains the same. So, if anybody can redo the SKUID, then your phone will work differently.
