Lost my network when I set the radio band to US

It was showing me H+ on the top instad of 4g
I did .#*#4636#*#* and changed the band from phone info to USA.
Now I have lost my phone network and its not coming up.
How can I fix it... so that my phone becomes useful :'/

Change it back to the way it was. Your not supposed to change anything besides the part to lte.

The problem is not with the sim
Just tested the sim on S3 and its working fine there.
@tcf38012 told me to download fastboot files and restore

you can flash stock rom use RSD lite.

Thank you guyz.
Flashing the stock via RSDLite fixed the problem.
I wonder we should have something like get ril for fixing our radioband problems
thank you anyways

Please help! No network signal anymore
Hello guys!
I am facing the exact problem. I also accidentally selected USA Band in Phone info menu and now not getting network bars anymore. I tried factory resetting but no luck. I am using this Motorola Atrix HD phone in India (SIM unlocked) and its rooted but Bootloader is locked. Its running on Stock JB 4.1.1
As suggested by some folks here to flash Modem or flash Stock ROM via RSD lite, I couldn't find the Stock 4.1.1 or Modem to download. Please help me fix the phone.
Thanks in advance!

I have same problem. Didn't see this topic before making new one.

Sad to know that you are also facing the same problem like me.
Did you try flashing MB886_att-user-4.1.1-9.8.0Q-97_MB886_FFW-20-27-release-keys-ATT-US_BuildA.xml.zip via RSD Lite? Hopefully it should fix the issue. I tried to download this Stock AT&T ROM but every time I have broken file error.

Glade to know that it worked for you ...
By the way which version of AT&T Stock ROM you flashed and was your phone Rooted with the Locked Bootloader?
My AHD is Rooted, Locked Bootloader and on Stock 4.1.1 so am I good to go? Do I need to Un-root it prior to flash through RSD Lite?
Thanks!

EDIT: I have fixed my rooted but locked AHD. Simply flashed Stock AT&T 4.1.1 using RSD Lite and phone got network signals again :victory:

dial *#*#4636*#*# and check network setting is set to GSM/WCDMA/LTE AUTO

Are your speeds any slower? I think some carriers call different things 4G, so with a non carrier specific ROM, you get a different graphic.
I think there's a way of changing it in the build prop.

I'm running the latest firmware

something tells me that this updated firmware has something to do with it.i have the same problem here i live in greece and i can't get lte either.damn..i know for a fact that the model i own mid 071000 or something like that is capable of using my carriers lte band. something is wrong with either the radio or with the roms i used in the past.it is going to be very hard to find the right compination..im gonna go to a store and see what the latest radio on their devices that came from factory for greece was and try to make something out of that..to make matters worse i didn't even saw LTE in the 4.3 updated firmware either..

doesn't mean that they are correct, my carrier's default APN settings are one thing, but in order to get LTE to work, I need to manually add an APN with the correct settings.

i dont receive 4G/LTE in general, i have tried different roms too, nothing seems to work

stock rom, no root and not registered on mobile network

I have a 9305 LTE, it will not register on mobile network, i flashed a stock 02 rom to it and it is still the same, it has not been rooted and the IMEI number is good as is the serial number, i have read all those threads and have tried wiping the cache and resetting..what else can be wrong ?

so you have no signal.. try a different modem or maybe your 02 firmware was corrupted redownload ttry again. and download from another website this time here you got one http://androidromupdate.com/2014/04...gt-i9305-android-4-3-firmware-manual-install/
hope this will help

i dont know the history of the phone and wondered if it had been black listed but i checked the imei number and its not.

hmm..theres a radio button next to o2 pay and go i checked it and went into another menu..most of the list says not set...

oh they are set..i pressed the + button..no i pressed the pay go name and it shows the settings but dont know if they are right or wrong

where do i research which modem i need

neither can make or recieve call when my network is set to GSM/WCDMA/LTE auto mode

I have a LG G Flex model LG-D958. I have this weird problem with making or receiving phone call. If I set the network mode to only GSM mode, then I can make call out and receive incoming phone call. Other than this setting, example when set to GSM/WCDMA/LTE auto mode, I could only access the internet network in WCDMA or LTE or EDGE mode for DATA access BUT could not receive or make phone call. If I make a call out, it will cut off after several seconds. When I tried calling to my this mobile number from another phone, I could only hear the annouced voicecall telling me that it could not be reached at the moment. Then, when I set it back to GSM only mode..then making or receiving call is back to normal.
My ANdroid version is 4.4.2. Can someone advise me what I can do to get my Flex works again? Thank you

This is an L23? Where are you located? Its to my understanding those are sold gsm Sim unlocked.
Is this a new Sim card? Is it a GSM network Sim?
Have you changed the software at all?

My model is LG-D958. I am not too sure what you meant L23?
I am from Thailand but currently in Malaysia.
Yes, this model is sold in THailand with open sim.
Yes, it is a new Sim card with GSM network that include 3G/4G network access.
THe software I see from the phone setting is D95820d-IND-XX; Android version is 4.4.2
appreciate your help..thanks

I'm not sure why you would have to change these radio settings at all. It should work right out of the box, except for your carriers specific APN settings.
Have you tried a factory reset? Start from scratch? Have you made any software changes?

Yes, it supposed to be.. I mean it works for everything except cannot make call if I set it to GSM/3G/4G auto mode. I have done a hard reset but the problem still persists. I was given this phone by my cousin and I am not sure whether any softwares was changed BUT I understand that the original Android version should be 4.2.2 - but now it is 4.4.2, do you think this could be the reason that is the cause of this weird problem?
Maybe it is good to totally unflash and reflash it back to its original software version. Can you guide me to doing this?
THank you

Or is there any way that i can run a diagnostic test from within the phone itself? Please advise too, thank you

According to the lg website it should only be on 4.2.2.
http://m.lg.com/au/smartphones/lg-G-Flex-D958
I think a fresh start using the lg flash tool would be best.
Make sure you get the right firmware/tot, for your model.
Can you ask ,whomever you got the phone from what and why he changed the software?

I rely heavily on internet, and lose my not so many marbles left when without it, I feel your pain.
From what I am seeing trying to look into your problem, you have done all that is suggested, other than a service centre visit
Hopefully someone who has suffered but resolved this will comment and share the steps for you :fingers-crossed:

waiting for your comment brother

Have you check your APN settings?
Replaced your SIM card? (It might work on other phones but not on yours either to not sitting properly or something else. So try replacing it.)
Take your sim card out and try this.
Do a factory reset and flash firmware with CSC file (not home-CSC file, backup first. )
Let phone boot without sim card first.

You're not going to get CDMA to work on the F version of the phone as far as I know you can only use GSM that's why nothing that's being suggested is working. You need to get a GSM carrier sim card.

Your device is SM-N950F/DS.
You are in india.
The phone can't connect to 4g/Lte after the security update. 2G and wifi is ok.
Before the update 4g/lte is fine.
You tried your simcard on other phones is able to connect to 4g/lte.
Is this correct?
May i ask how did you update to the latest firmware? ota, odin or smart switch?
