Hello everyone, I think I made a mess...
I have a Le Max 2 X820, I went to the secret menu (*#*#4636#*#*) > phone info > 3 dots menu > select radio band > and i selected "band mode 6". All of this because I had 4G signal issues.
I thought I had solved because the 4G worked perfectly but I just found out that I can not make calls! While I try to call someone it loses the signal and displays a network error.
I tried to reflash the ROM, to flash another ROM with all the wipes, tried to reflash stock modem.zip but nothing! I am desperate! Please help me
EDIT: On the second SIM slot it works, I can make calls
EDIT 2: if I do a manual network search in slot 1 only appears 4G but if I do a network scan on slot 2 appear 4G, 3G and 2G so I can make calls
I did what you did 2 weeks ago on my x829,i think both options band 6 and usa bands just disabled 2g and 3g bands and i can get it to work with qpst or qxdm easily.

yesterday,i set the gsm/umts band to [usa band]

but i the test mode,i just got the usa band to choose
i have reflash the rom again,but it doesn't get any better
how can i do???
Contact your carrier to setup the apn, the screen shot is for canada, telus. Make sure that the fields are properly competed.
System settings - more.. (under data) - access points.

"yesterday,i set the gsm/umts band to [usa band]"
Where did you do "this?"
In the hidden phone menu, I assume?

Help, i think that there's something wrong with my phone. The signal coverage of my phone is sometimes missing without any reason, and will appear a minutes later or will appear if i set my phone airplane mode to on and off again.
I tried to use move my simcard to my other phone and there's no problem with the signal.
The problem is 'cause you have a not 4G SIM CARD, and the phone is trying to get 4G signal. To fix this:
1. Get a 4G SIM CARD
or
2. Go to Network Menu and select 3G prefered.
I got the same problem and i have 4g sim. I don't no what is the problem. In my case may be the methal bumper but after change it with one from silicon i still got the problem. May be the thempered glass from back of the phone?
I got the same problem and i have 4g sim. I don't no what is the problem.In my case if i select GSM in mobile network its working fined but if i changed to WCDMA i have signal problem /

Isn't there one of the option where it chooses either WCDMA or GSM?
LTE (preferred)/WCDMA/GSM
Tap >> settings >> ...more >> mobile network >> preferred network type
Check the setting is 'LTE (preferred)/WCDMA/GSM'
And not 'WCDMA only'
And not 'GSM only'
Also if you are using a dual SIM phone like I do then do this:
SIM1 = 'GSM only' where the network is a GSM one.
SIM2 - 'LTE (preferred)/WCDMA/GSM' where the network is a WCDMA one.
i have a problem about my 2nd sim. i have two sim card and both are belong to the same network carrier. 4g indication is only shown on 1st sim card. when i turn the prefered data sim card to 2nd sim, 2nd sim always on 2g connection even lte is prefered. i swaped the sim cards and 2nd sim still shows 2g conncetion, so the problem is not about sim cards or carrier.i checked that when i put the cellular network to manual mode instead of automatic and data is selected sim 1, 4g networks appear in the search list. when the sim card 2 is selected as data and search for network, only 2g networks appear in the list.
sim 1 4G sim 2 2G OK
sim 1 2G sim 2 4G Not OK. both sims work on 2G (or sim 1 is 3G, i can not see any indication on top )
i checked the *#*#4636#*#* testing mode and both prefered network types are selected the same "td-scdma, gsm/wcdma and LTE"
when i bought the mobile phone, i had not got such a problem like this. i made imei repair operation and my phone works like this after imei repairing. i also test my imei numbers on both sims and still the same.
What is the rom version you are having now?

global developer 6.4.9 beta. i already tested on several roms.
upps
I have exactly the same problem! I had bought the phone from a chinese vendor and I hade 3G only in SIM1 and 4G in SIM2 . I used a guide and flashed a global qcn and restored the IMEI cause it was lost and after that I face the exact same problems as Salagil
Hi am Haruna from Ghana.
I bought Alcatel Ideal 4060a (AT&T) model a couple of months ago, but problem is that the network doesn't change at all its always at 2g/EDGE no matter what i do or which network i put inside the phone.
Am currently using MTN (Scancom) which is a 4g Sim card and the phone is unlocked to any network.
And there is no option in the settings that you normally choose from your preferred network mode.
So i stated googling for the solution when i came across this code (*#*#4636#*#*) which i can use to change my preferred network, but whenever i change it, nothing happen, i mean nothing at all, all it does is that, when i select "only WCDMA" i will not get service/network, when i select "LTE only" no network, the only thing that work is GSM or WCDMA preferred.
So guys i urgently need your help as am getting frustrating by this phone.
E/GPRS is slow max u can get is 28KiBps, switch to 3g or 4g, it also depended on your att network coverage, Are you living inside bunker?
My H961N does not allow me to independently set my network band for each sim card. Both my network providers operate on 2G/3G/4G however since I have gotten this V10 I have had inconsistent network usage. At first I would strongly get one network and the other would mostly be on Emergency Calls when indoors depending on where I was. I used the hidden menu code *#546368#*961#-> Field Test -> Modem Settings, from Modem Settins I have tried to set the RAT Selection and the Network Mode however when I check Engineering Mode both sims show the same band if I am on WCDMA Only or GSM Only but neither provider operators on the same band except for one on 3G. If RAT is set to selectively move between two or more frequencies then one sim shows Invalid Band in Engineering Mode. Using Network Mode I have tried to set each sim to different band but both would either show the same band or one would appear invalid under Engineering Mode.
Another Issue I have is I am unable to use data even though I have the correct APN for both of my Network Providers. I have verified that both sims do work when used in another phone, at one point I visited both Providers but none could give me an answer to my issue. One of my Providers did however try and activated a data plan while I was in their office and the V10 did show 3G and received data however upon returning back to my regular surroundings I no longer got any data. I have tried upgrading the V10 to Marshmallow and Nougat but the upgrade did not solve this problem, neither the one I stated before. But on Nougat both my sims did show 3G but strangely only when I have my Wifi active and using a VPN. Currently I am on Lollipop and rooted I considered trying to flashing a qcn, sec and nvm files since I saw a site listing them as fixing network and data issues on this particular phone, I have the files just in case. Any help would be greatly appreciated.
