The system and nfc update does not work

[Lukki]

Translation via Google Translate:

Hello,

At the beginning, I must say that the phone came to me two days ago from China.

I have a problem with the software update. In the information about updates, he writes that my software is up to date when it is not possible because 4.4.4 KitKat is a very old version .. I also tried using a program on the computer but with no result. I also write on the program that my software is up to date and the attempt to repair the software has failed.

The second case is nfc which probably does not work because I can not connect to another device, I tried to read the card with the nfc function, and pay by phone via android pay with a poor result ..

Thank you in advance for help.

Regards.

Witam,

Na początku trzeba powiedzieć, że telefon przyszedł mi dwa dni temu z chin.

Mam problem z aktualizacją oprogramowania. W informacjach o aktualizacjach pisze, że moje oprogramowanie jest aktualne kiedy to nie jest możliwe bo 4.4.4 KitKat to bardzo stara wersja.. Próbowałem też za pomocą programu na komputerze ale bez rezultatu. Na programie też piszę że moje oprogramowanie jest aktualne, a próba naprawy oprogramowania się nie powiodła.

Druga sprawa to nfc które raczej nie działa bo nie mogę się połączyć z innym urządzeniem, próbowałem odczytać kartę z funkcją nfc, oraz płacić telefonem przez android pay z marnym skutkiem.. 

Za pomoc z góry dziękuję.

Pozdrawiam.

This phone is customized and locked to Play Poland, and the latest available firmware is 23.5.A.1.291 (Android 6.0.1 Marshmallow). So, connect your phone to a PC/Laptop with Xperia Companion installed on it and use it to update your phone.

I am on the newest update, and nfc still not working. firmware is Poland Orange, bootloader is blocked, and can't install non stock roms. sony doesn't do nothing with many software issues on LP MM, and if nothing changes i don't see an option. have to sell this junk, and return to samsung and ODIN. they give u freedom in fixing. i was a fan of Sony till sony erricsson w910 and similar models with software errors loops etc. this z3 (d6603) was a return, but i see nothing has changed. u just sell and don't care. but the worst thing is that u block the option to upgrade it by concept software. w910 had SEUS but now a good hardware is junk cause of buggy software, and nonsense locking of loader. what is the point? cause i don't see any. after few days looking for a solution i see that i don't want any sony device and the same is for Orange. you make life more difficult. better option would be selling an unlocked device with no warranty, than locking it without support. and no support for bluetooth headsets in ps4 is also fantastic. but i sold ps4 instead of buying your headphones. fingers crossed for new good ideas. maybe square jack for audio??? or round sim card...

is there a way to find a service manual for z3? or to unlock loader without tryin to ask Orange?? Cause no root, recovery, and no google pay cause of no NFC is annoying. and the number of bugs on LP and MM stock based roms and your support in fixing them is scarry. dual boot on my galaxy s4 was more stable and had all the stock profits, and a stable nugat aosp mainly for dolby atmos. so i don't want to judge anyone, but few progrmmers, working at home had a lot better results than your army of programmers.

now i'm havin, problems with XC software repair... it can not download the firmware... jeez

and your diagnostic app says that NFC is ok but it isn't and the service menu test gives an error. by the way your diagnostics say that "Deer Hunting 2018" installed few days ago is an system app. but thats just funny, not a problem, but it recommended me to contact Sony so i wrote it as u wish. sorry for my english, but i am wasted after searching some fixes...
