4g network problem after update OS

Hi,I don't whether is the reply or question threat. I'm using honor 4X che L04. I can't use 4g sim in my mobile I'm not talking about only jio can't use any other 4g sim. Sometimes it works for few minutes after in wipe format my mobile and when I tried to call through 4g network went off. It all start happened when I updated my OS.
Does this happen to anyone else?
Is this a mobile network problem or firmware problem?
Could it be repair by flashing the mobile?
Or is there any solution?
If flashing is solution could someone tell me how to flash it please?

LTE Band Question

Hi everyone,
My carrier band is supported on the Mix namely B3 and B7. However, it is not possible to get 4G signal at all on the phone, only 3G.
Any suggestions?
Thanks

Settings/SIM card/preferred network
Or maybe you need to setup APN manually.

Thanks for the suggestions but I have tried that to no avail. I install the LTE discovery app and there is no LTE signal at all.
I also tried flashing the modem file from China dev rom but it is also the same.

So your old phone worked ok? Can you try a different carrier SIM card to check.

What carrier are you on and what are your APN settings?

I'm in Singapore and my carrier is Starhub. The apn settings are auto created and I double checked against other phone it is the same settings.

There is an issue with the latest update that causes the device not to connect to LTE. According to the official forum, it should be fixed in the next update, which is about a week away.
Edit: Some have suggested reflashing your ROM and doing a factory reset as well. Most of what I have seen points to the developer ROM. If you are using the developer ROM, then flashing back to the Chinese Stable and factory resetting the device should solve it. If you are using a vendor ROM, the same is recommended.

Just an update to anyone facing the same issue. This is a bug on the development rom and hence it affects all eu / custom rom that derive from there. Once flash onto the latest stable will resolve this issue.

Like jio sim supports only 4g network, when i insert jio sim it shows emergency call only and when i insert airtel 4g sim, it works only on 3g doesn't show 4g icon on notification bar. I tried with all basic required ideas to check LTE network if working or not. Its not working

There are 5 smartphones at my home as all are using jio so network coverage is fine. I have also tried with 2, 3 different jio sim in my phone same issue. I am sure there is fault of LTE driver or else software fault

I don't own a 4X. If it is indeed a hardware problem, service center is your best bet.

Network Issues on my k3 note

Hello guys..
I am a K3 note user and I have been facing network related problems with my phone after a few months of purchase.
I am using Airtel 4G sim card that works fine on other mobiles but not on my phone. I tried using other sim cards , but no network at all. The phone becomes quite warm when there is no signal. I was on stock ROM before and now I am using a custom ROM( Resurrection) to see if I can get my problem solved.
I tried all possible fixes and solutions that I found over the internet, but yet no result.
Please!!! can someone help me resolve this issue because I have a phone that cannot perform this basic task.
If there are issues with the hardware, how do I check that?
Or is there any patch or build prop edits for this issue?? Please share....
Thanks in Advance...

Its very simple..
First I installed custom recovery(TWRP 3.0) using sp flash tool. Then i downloaded ressurection rom and copied to my storage.
Using TWRP I took a backup of my current system(android 6.0) and wiped cache/data/system. Then i flashed the RR Rom zip file from TWRP.
