Meizu MX5 no 4G network capabilities



Hello,

I have been using my Meizu MX5 for about two months now without the 4G network working. I have recently updated to the latest firmware and I am currently running Flyme OS 4.5.2.7A and that has not solved any issues either.
I have checked that the phone settings are configured properly.
Network Mode is set to "4G First".
The phone is pending between, H-, H and H+ connection (3G I believe?)

I have checked with my provider and these are the following frequencies which should be providing 4G in my country (Sweden) for the provider:
800Mhz, 900MHz, 1800MHz, 2600MHz

Other providers have the same frequencies as well.
I have also gotten two new SIM-Cards during this period of time without it solving any issues. I have tried the SIM cards in some other phones and they get 4G connection without any issues.

I have been in contact with Meizu customer support in China and after some random troubleshooting of factory resetting and reinstalling the same firmware on the phone without solving anything.
They have also provided me information regarding the different bands/frequencies which the phone operates on:
GSM/GPRS/EDGE (900/1800/1900MHz)
WCDMA/HSPA+: Band 1/2/8 (900/2100MHz)
FDD LTE: Band 1/3 (1800/2100MHz)
TD-SCDMA: Band 34/39 (no freqency specified)
TD-LTE: Band 38/39/40/41 (no frequency specified)

I am not 100% sure on how this works but according to the information I am given, the phone and my provider share at least one frequency for the 4G network and therefore I do not understand why it is not working.

I am sure that it is software related and thus I won't send my phone back to China (4-8 weeks delivery time and all expenses has to be paid by me) for them to troubleshoot.

Anyone here who has knowledge which could give me an answer?

Kind regards,
Martin
