Hey guys, apologies if this has been asked before or if this is a silly question.
I recently bought an Asian Lg G3 d855. The software version is D85510e-GLOBAL-COM.
The phone is working fine apart from not having any 4g connectivity. I have went into settings and tried to change to GSM/WCDMA/LTE auto but it doesn't connect to 4g and switches back to GSM/WCDMA auto as soon as I exit the screen.
I have also went into the hidden menu, to LTE ONLY, RAT selection and tried to change it there but still no 4g. If I choose "LTE only" I lose my signal completely.
I have also went into band selection and chosen band 20, as this is the LTE band for my network in the UK (O2). It says success when I click on it but still no 4g.
My question is, is it possible to flash a European software version and would this enable the 4g?
Or is there any other way to enable 4g on this phone?
Thanks in advance!
Guys does anyone know how to ho into Engneering mode in honor 7x. Or how to change network band manually. I need to lock band 3 in my device for better network, but can't find engineering mode. Help plz..!
I need to know how to lock band 3 too, we need a similar app like network signal guru for our honor..
If you try to change bands in the service menu (e.g. from Band 4 to band 2) and you have LTE but phone calls don't work at all (just says call ended instantly), just go to "network mode" and select automatic, which will get voice working again on your new band.
Turning the sim card off and back on won't fix that--that will just make the band reset to default (with voice working) which isn't want you wanted if you were switching bands.
This can be useful on low tier providers if one band is lagging horribly and another band is more reliable.
I just recently discovered the service menu, does this actually enable bands that normally aren't active? I see Band 71 here which I thought was only available on the TMobile US variant, yet here I am with the ULM model and it shows it in the menu. I'd like to enable it in case I'm ever in an area that supports it, but I'm not sure what this menu actually does?
Please leave "Thanks" if this thread helped you.
_____________METHOD : 1________________
1. Open dialer and type : *#*#4636#*#*
2. Choose SIM1 or SIM2 to enter reception menu.
3. From dropdown menu ( LTE/UMTS auto (prl) as default ) change it to : GSM only
4. Wait until your cellular will reset and turn back on.
5. Less dBm amount = better signal strenght.
6. Test best signal for your network and share it in comments.

_____________METHOD : 2________________
1. Open SIM tray
2. Change your SIM car slot to Slot 2
3. Check if your signal strenght increased and share it in comments.

I'm waiting for my RN8Pro. Is there signal strength issue by default?
You can change this in network settings menu the normal people way and also allowing only GSM will relegate you to 2g network that has indeed better signal but will kill your internet speeds.

A little bit I think. At my house, with Redmi note 7 I have 4G+ ,with Redmi note 8 pro I don't have 4G+ so often and on places that I have it with Redmi note 7
How to increase the sharpness of incoming call voice? Most of the time, voice is muffled.
The incoming voice leaks from the back of the front speaker too
how to increase the volume of the headphone and speaker?

I try this.. when I change LTE/UMTS auto to GSM only I loose 4G and have only H+ that is slower than 4G.. and the signal is the same.. I try it on one spot for half an hour
2G has almost everywhere coverage and it's too old technology to use.
When UE is registered to 2G network it can't handle voice+data transmission simultanously (most networks does not support DTM technology).
Also 2G is not designed to used AMR-WB voice codec, only simple AMR which sounds like **** to be honest.
So this tutorial is pointless, sacrifice better data speed for rubbish voice and ultra slow data speed

Redmi NOte 8 Pro has big problems with LTE 4G + tape management. The phone does not keep the 4G + it switches and stays in 4G all the time. It's a modem management problem that does not support the double-banding needed for 4G +.

Xiaomi Redmi Note 8 Pro model M1906G7I (Global) doesn't connect to 4G LTE
Hi there! My problem is even worse than this you are sharing with us. I bought a Xiaomi Redmi Note 8 Pro model M1906G7I (Global). However, there is a lie about it, the specifications indicate that about networks it works for the following 4G LTE bands: B1/B2/B3/B4/B5/B7/B8/B20/B28, but it is not true as it only works for B1/B3/B5/B8/B40/B41 (I found it out by entering to engineer mode *#*#3646633#*#*). Therefore, in my case I can only connect to 3G because my service carrier uses B4 (1700 mhz, 2100 mhz) for 4G LTE. Besides that, everything is fine with the phone. What I am trying to find out is whether it is possible to activate or unlock the B4 band so that it can connect to 4G LTE. If anybody knows about a solution to this issue, I would appreciate the assistance to this matter.
Hi,
You don't have the global version M1906G7G
Global : B1/B2/B3/B4/B5/B7/B8/B20/B28/B38/B40
China : B1/B3/B5/B8/B34/B38/B39/B40/B41
India : B1/B3/B5/B8/B40/B41
You must get a refund if you bought the global version, and change to the M1906G7G to be able to use B4 .
I just tried this on my note 8t. Switched to GSM only and immediately even before restarting the phone, went from 1 bar to full bars. Speed tests show much more bandwidth available (now at 11.8mbps/3.1mbps). Sweet. First post I found after a search and first solution just flat out worked. Still think I should be getting higher speeds (I don't think I have ever really cared about the mobile speed because I am almost always on wifi, and do not recall ever doing a speed test, but at least it's better than it was now.
Hi,
has anyone managed to get the S20 Ultra working on LTE only.
This isn't working for me. But I would prefer LTE Only without limiting it to a certain Band anyway.
I'm rather preferring to get no carrier but a crappy Network like Edge (2G). LTE Only worked perfectly on my Mate20 Pro since German Telekom has a pretty decent LTE coverage even in the sparsely populated countryside.
Thanks.
You can fix one technology or even bands by using the QuickShortcutMaker (in the play store) - there you enter in the call settings - and go to the last option. There you can set your prefernces, e.g. using only LTE 4G. The whole procedure is explained step by step in this youtube video https://youtu.be/K-DN0q64lRw
I found this solution, which is also for me very useful in this thread https://forum.xda-developers.com/galaxy-s20-ultra/help/samsung-band-lock-exynos-t4071125
