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
Hi mate.
I had this problem but upgraded to new firmware late last night and it came on. Thankfully!
Give it a try
Hi,
I have checked the upgrade app on the phone and it says I have the latest firmware.
Which firmware version are you running?
Kind regards,
Martin
Maybe it is an APN related problem. Look if you have the same data as in the other phones that 4G works

Hi iicc,
Thank you for the reply.
I have checked the APN settings about four-five times and I can't find any inconsistencies. I have even crosschecked it with a support technician from my provider.
The only things I can think of is either my anntenna being gimped, that the firmware is not properly developed or that somehow there's trash in my system and that my phone maybe needs a complete wipe and reinstallation.
After the upgrade to firmware 4.5.2.7A the phone does not even hint on trying to connect to 4G. Pre-upgrade it atleast connected to 4G for about 5 seconds and then went down to 3G.
Kind regards,
Martin

And have you tried to factory data reset the phone?

Let me try to come up with something that might be your problem. If you are using 3 as your mobile provider then they use FDD-LTE band 7 & 20 none of which are supported by the MX5 and 3 are also using TDD-LTE band 38 which is supported by the MX5, but might not be available in your area.
If you are on Net4Mobility then they use FDD-LTE 3,7,8 & 20 of which only 3 is supported, so it could that in your area there is no coverage with band 3.
If you are on Telia, the story is pretty much the same as Net4Mobility as they use FDD-LTE 3,7 & 20.
In order to get more from your phone. You can open up google and search for 'meizifan eu' and go to the website. They have a pretty good description of how you install the international version of FlyMe on your MX5, the international version is called 4.5.2.7i. I believe it activates some other FDD-LTE and TDD-LTE bands.
1800Mhz band is a short range, higher bandwidth frequency which usually is less common and given that it has a short range it most likely isn't available in your area.

Thank you for the reply nasty_suicide!
I am using Comviq Tele2 as provider, which should use the Telia net.
This is what I believe as well, but I really thought there was no way to flash the international version onto the phone and was about to abandon ship by buying a new phone yet again.
I will try to install the International version as soon as I have time to follow through the steps. I have found the guide on Meizufans.
Once I have installed the international version I'll let everyone know the outcome.
Kind regards,
Martin
Hi Hawdes,
I've exactly the same problem as you do, please post back once you instal I version. I was planning to do so but since I already have everything installed I didn't want to go through trouble for nothing.
What were the results of this? Is it true that firmware can affect the signal received?
upgraded to the latest firmware yet?
Samsung galaxy s7 4G problem
What about in Samsung galaxy s7 version of Flyme OS?? I cannot see 4G option.
T-Mobile's tower in the area I work in is always congested to the point that I cannot use data when connected to Band 12.
On LP I connect to band 4 and works fine but would like to run MM
Can anyone tell me if there is a modem for MM that does not support Band 12 or point me to a firmware?
I have a SGS 8 SM-G950FD.
a few days ago, I noticed that the LTE signals on my phone were fluctuating a lot between 1 - 3 bars and then suddenly reverting to H+ and staying there.
At first, I though it's just network issue. however, days after, the issue still persists.
The said issue appears on Telenor Pak Band 5 (850MHz) LTE. It happens whether the phone is indoors or outdoors. Same sim on other phones works good with LTE.
However, I tried to use LTE SIM of another network (Band 3 1800 MHZ) and that is working flawlessly.
Tried factory data reset, reflashing stock firmware. Na da .
Any help would be appreciated.

It's issue with lower band frequency 850 and 900
I rolled back to April firmware to get network band locking but still it was the same.... Need to visit Samsung center or warranty provider
Hi,
my device doesn't work properly. When I'm outside of my city my redmi doesn't have network but others have it.
Last night I have check the band I'm connected and the result is 41. I live in Spain and there isn't any company that works with this band.
Anyone can help me? Can I change the band?
To check my band I have used LTE Discovery from Play Store
Anyone have any solutions to this problem? Network signal guru has no B20 band that can be enabled.
As for now it looks like we'll have to wait for a patch from Xiaomi.
There are loads of threas about missing band issues reported at miui.com and here as well in various threads.
Yes. I changed the frequency band in the engineers menu.. You got to look hard or you will miss the drop down menu.. Phone dialer.. *#*#4636#*#* I think it was.. Then I can't remember where it was but its there and only takes effect when you restart phone. Mine was on some basic Chinese frequency so no UK band 20...was stuck on 3g but now shows 4g..Happy days
