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
Phone's Details :
CV: 1285-4242_R13A
Model :L50u
FW: 17.1.f.0.60
Brand :China Unicom
Sim lock status on service window is all 0
DRM keys are gone [unknown error][active]
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.
