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

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

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?

What about in Samsung galaxy s7 version of Flyme OS?? I cannot see 4G option.

No Lte connection

Hi everyone
So I've had the mi a1 for a couple of days and so far have not been able to connect to lte network. 3g is working. Apn is set and configured correctly. This is in areas where my Redmi 4x, previous note 4x and all other devices connect to lte networks (same sim card obviously). I have the global version and have immediately installed the September update after setting up the device. I suppose no-one else has issues with lte, otherwise I would have found a thread about it? Are there any suggestions what I can do to find out what the problem is? I tried an app to force lte only but it doesn't connect to a network when set to lte only.

Nevermind. Restarting and cycling through 2g/3g/4g options in mobile network menu resulted in 4g connecting. Still a bit odd though as I'd cycled 3g/4g before and only connecting to 3g signal. Restarted once after the update as well.

Suggestions on 4G LTE stick for use with Android HU and AT&T in the US

So I have a free spot on my family plan and was thinking I could just get a BYOD sim and stick it in a 4G LTE stick for use with my Android HU. All the ones I have seen has compatible miss all the relevant bands for US use, specifically for AT&T. Does anyone in the US have any suggestions?

I second this thread for Verizon.

So I finally got my dongle and SIM card and it is working and pretty much without any extra apps or root.
I purchased the HUAWEI E397 4G usb dongle 100M data card Unlocked 4G LTE MODEM B397Bu-501 - the important part is the -501 at the end they have several models with different band compatibility and the 501 was the one with AT&T compatibility.
On my Eonon GA2167 after I installed the stick the Cellular Networks entry showed up automatically in the options, I was able to edit the APN data there (you will likely want to be connected to wifi when you do this, if it's trying to provision data you wont be able to select APN data). I just copied the APN data from my phone and it worked. Using Cricket (AT&T).
I had some trouble getting it to work at first, it would recognize the USB stick allow me to edit APN and then connect to the network but I had no data connectivity. Eventually it started working. Not sure if this was after I copied every APN setting (previously I had just entered name, apn and the MNC and MCC) once I added the MMS/MMSC data and APN type it started working a little after that. But it could also been on the network side since it was a new SIM I had just activated hours earlier and had been inserted into 2 other phones (to help try to activate it).
Anyway if someone wants a stick that works on AT&T bands in the US this should work. The headunit only shows a 3G connection and reports WCDMA with signal check lite, but I think that's due to the firmware of the HU not being setup for 4G LTE, with a speed test I get about 8-9 Mbps down and 6-7 up, not super fast but I believe that is LTE speeds since HSPDA doesn't support uploads that fast, also the stick itself shows a cyan LED with is meant to be for LTE connected network. Either way its way faster than the wifi connected to the hotspot on my phone (not sure if its the wifi antenna or what but wifi performance is very subpar on this unit). Also it connects quicker on startup (and does so automatically) than wifi.

Thank you for this info! Where did you buy yours?
Has anyone tried this on a Joying_JY-UM135N or JY-UM135N2?
When I look at this listing on aliexpress, further down, it lists a number of "Network Bands", including the -501. How should I interpret this? Does the modem support all those bands, or do I have to specify when ordering? When I search for "huawei e397" on Amazon, it shows me a -53 version. Is this the same as the -501, or different? I'm also curious as to why the only hit I get on aliexpress is a listing in the Netherlands. ??

There are 5 different variants (2 off which offer CDMA/EVDO for 3/2G). They are all the same base stick but vary depending on bands supported.
This website details each on and the bands its supports: https://www.4gltemall.com/huawei-e397-4g-lte-mobile-internet-key.html
I bought mine from Aliexpress, you will want to make sure you specifically get the -501 for AT&T I believe the -53 supports some T-Mobile bands.
You might want to hold off till I can report more tho. After initially getting it working, it is proving to be inconsistent, I'm not sure if its a low power issue (I have ordered a Y USB cable) or something else. The -501 don't support the full compliment of AT&T bands and I'm not sure if that is the problem, it is missing band 2 for 3G and Bands 2, 4 and 12 (though 17 is kind of part of 12). I know in my area they use Band 2 for both LTE and 3G and I'm not sure if that is my issue. I seem to struggle to get it to work at home but if I am driving around town it will pop up and connect, FWIW once its connected its solid even at home until I disconnect and try to reconnect.
I will update has I make progress.

I have the exact same head unit and have the exact same issue, except I live in Australia and I'm pretty sure I have a spare Telstra (AU telco) dongle lying around, so it literally just works right out of the box? I thought these do support 4G, or at least I thought I saw it advertised like that (or maybe those are the Android 8.0 ones). What else have you done with your head unit OP, not many ppl it seems have this model and look to modify it lol.

It supports 4G speeds, when I get a connection in a 4G area on a band my dongle supports, the icon on the headunit shows 3G, but I get 4G speeds. I thinks its just a case of the limited firmware not supporting the icons and reporting for 4G but since all data transfer is handled by the stick then it works at those speeds.
A bit of an update. I bought a USB Y cable in case lower power was an issue, for the first 4 times after getting the cable things worked right away at boot up with no interference, that was a couple of days ago, since then it hasn't happened since. I am likely going to order a Momentum 313U, its AT&T branded and supports its full compliment of bands, but no idea on Android support. The only 2 things I could find about Android support was a generic listing on Aliexpress showing what appeared to be a 313U and stating it was an Android device and a Pilipino website saying it wasn't recognized by an Android Tablet (I think that's what google translate was telling me).
Failing that I will order a Huawei 303C, it supports the full compliment of AT&T 3G bands and is on the confirmed working list. No 4G but I think AT&T still has full coverage of HSPDA in my area along with LTE.

I have the exact same head unit from eonon and purchased the AT&T usb velocity stick off their site and plugged it into the USB port and it does not recognize it. The led is lit up on the stick but nothing on the head unit. It would be nice since this one has external antenna ports and supports LTE. Is there any software I need to install on the head unit?

Another update: I ended up buying a Huawei E303c stick, works on all the AT&T 3G bands and I haven't had an issue with it at all. max download speed has been around 3 Mbps but that is enough for voice commands, Pandora and navigation so I'm happy. I got closer 10+Mbps with the 4G stick, but I only worked some of the time (I think due to AT&T using multiple 4G bands in my area and the stick not supporting them all).
Anyway the Huawei E397 is up for sale and I'll suffer with 3G speeds.

I just got a Huawei E303c stick for AT&T. I plugged it into my generic Atcgfheny Oreo head unit and it shows no 3G icons. It blinks a blue light, but not connectivity on the head unit. Is there something else I need to configure? I can't find any settings in the menu.

LG-H990ds compatibility in UK?

I've just bought a V20 and noticed that it's a Taiwanese model (model LG-H990DS, with TWN firmware). The first two issues that I've noticed are:
- it won't connect to 4G (I'm on Plusnet Mobile, which uses the EE network). It will only connect to 2G according to the notification bar
- it won't connect to either the 2.4GHz or 5GHz wifi networks on my Asus RT-AC68U router (although it will connect to a Belkin access point that I have elsewhere in the house).
Are the above caused by basic hardware incompatibilities, or can they be resolved by a firmware update?

Hi
The H990DS should have no problem connecting EE network as it is The Global version and supports LTE bands 3,7 and 20 which are used in UK and EE uses 3 and 7. I have a Verizon V20 which I use on Virgin and it has no problem connecting as Virgin piggyback on EE as well.
It may be your firmware needs updating.

My current firmware is V10i-TWN-XX. Should I be looking for a different version? If so, what's the recommended way of obtaining and flashing it?

That is the most current version of the firmware.
Theoretically Oreo will be released in August, barring further delays.
Silly thoughts:
Which SIM card slot is the SIM in? 1 or 2? It can make a difference when using two SIM's - only one will get 4G/LTE while the other gets 2G.
Is the phone new, never previously been used?
Finally see the attached screenshot of the network settings under: Networks/More/Mobile Networks/Network Mode. If for some reason it got set to 2G that could be the problem.
Note: I'm only using 3G network access so that's why in the screenshot it only shows 3G (Notification bar) even though it's set to auto LTE.
As for the WiFi issues, mine seems to be a bit quirky in not always connecting to some routers, 99% is no problem then you can run into one that for what ever reason it refuses to connect. At the radio station I work at (part time) my V20 simply refuses to connect even though I have the password. Works fine with my tablet & Motorola phone but no go on the V20. Go figure.
Best of luck figuring it out.

Thanks for that. I have my SIM in the SIM1 slot, and my Preferred Network Mode is GSM/WCDMA/LTE Auto, which I guess is correct. The phone is second-hand (bought from Music Magpie).
I have now managed to get 3G (with "H" displayed - HSPA presumably), but I haven't been able to get 4G anywhere that I've travelled in London so far.
In the last day it has also finally recognised my Asus router, so that's a big step forward.

Hey i have an lg v20 h990n as far as can tell from reading specs its got the same frequencies and bands mine works totally fine with ee o2 and vodafone its suppose to work with three ... it also works with my tp link vr600v2 works fine with 5ghz and 2.4ghz also my sisters and partners carrier supplied routers i might suggest that you received a defective one id return it if you cant get it sorted music magpie charge loads too for this phone

One Plus Five LOS 19.1 LTE Stopped working

I'm running the latest nightly build of LOS 19.1 on my One Plus Five. Suddenly, after years using LTE with no problems, today, I can no longer make LTE connections. This happens when out and about and also at home, where I have solid LTE coverage. Also, my wife's iPhone using the same T-Mobile account makes LTE connections when next to mine. The One Plus 5 reports an Edge connection, but now and then it reports LTE just briefly. I verified my cell carrier account has no issues.
I downloaded the stock OOS 10.0.1 firmware+radio zip package and flashed it via adb sideload. That succeeded, but it didn't help. APN and preferred Network settings are correct, I think (same was what always worked), so I'm wondering if I have a hardware problem.
Is there a way I can verify that the radio hardware is causing the problem? I have the LTE Discovery App, but I'm not informed sufficiently to know how to make sense of all the advanced data. Are there other modems I can try flashing?

I discovered the source of the problem. I had set Private VPMn from Automatic to Off when dealing with a problem connecting to hotel wifi. I didn't realize that would make the phone unable to connect to LTE, but apparently, it did.
