++please>>>helppppppp - Atrix 4G Q&A, Help & Troubleshooting

my atrix was fine today, but the signal suddenly disappeared from my carrier, and not make calls anymore. when I put my SIM card in another phone it recognizes the signal from my carrier and I can call. any ideas?
thanks
HELP!!!!
please
can be a problem in the GSM frequency?? Because I can find other carrier..
may have burned only one frequency?
how to check?
is possible to burn only the 2100 mhz frequence??

1. Try to search network in setting. Than choose your carrier..
2. Last way is to flash your atrix.

Power off / power on the phone. Double check your network and APN settings. Otherwise you might be looking at a factory data reset...

Last night at this time, 4 people I was with had full bars on AT&T, none of us could download/upload or make calls. 2 iphones, 2 android. Someone with a Verizon phone was fine.

Maybe your sim card broke?

Are you still without a signal?
Have you tried the factory reset yet?...

if you can, try someone elses sim card in your phone. Its a long shot but I have seen it work in the past. If it works, takes it out and then put yours in. Otherwise Flash SBF, or take it in for warranty replacement.

Just out of curiosity, have you installed any weird 3rd party apps recently?...

Might not explain the calling, but do you have anything in your APN list?
Settings -> Wireless & Networks -> Mobile Networks -> Access Point Names
If Access Point Names (APN) is Blank, then try manually adding yours in from this Master APN List Thread...

I'd just make a call, and then when I try to do another (some time later) had no more signal. the phone still works ... all turn out!

Network settings keep forcing GSM/UMTS

So, while tweaking settings using *#*#4636#*#*, I've apparently disabled the MoPho's recognition of the Sprint network entirely, and now the phone continues to reset itself to GSM/UMTS only in Network settings, even after reboot, and even after i change the settings manually to "any CDMA" or "Sprint" after the fact.
4G however, works.
(shrugs)
This is a first for me, and a headscratcher. Definitely don't want to go the hard reset route. Any suggestions of what I should be looking for?
**Update** - Have somehow managed to get it to stop forcing itself to GSM/UMTS, but will now only set itself on Automatic, and will not allow me to set "Any CDMA" or "Sprint only". Clicking these options won't stick, and just reverts to Automatic.
Preferred network type in Phone Info is "GSM/CDMA auto (PRL). I've turned the radio off/on several times, and it still shows as searching for service.
Sigh..
**Update #2** - Factory data reset didn't do the trick; phone still can't locate network. I'm sure this has got to be an easy fix. Anybody?
**Update #3** - Sprint couldn't figure it out either, chalked it up to a bug, and swapped out the phone for a 3D since they didn't have any MoPho's in stock. Would still be curious to know if anyone else ever encountered this issue..

Just out of curiosity, coyld you try putting in a sim chip and see if your phone recognizes it? Also, what is your baseband?
Sent from my MB855 using xda premium
That is indeed a bug of the stock firmware. Only way to fix it is to sbf back to stock. Hopefully you are not on the latest OTA (235) as I believe you can not sbf that version (downgrade).
Did the same thing myself by tooling around in the debug menus.

this problem appeared when using *#*#4636#*#*,and select gsm mode with radio usa band
now device keep settings forcing GSM/UMTS,i can not change the settings manually to CDMA (have other phone no.in CDMA network
--------------------------------------------------------------------------------
Encountered the same issue when I selected USA band. Did several things and nothing good happened. Finally flashed 235_radio_only.sbf from peetr_ and it worked. GSM 3G is working and 4G seems ok but unable to test it as I am not in US.

[Q] Samsung Dive only works when connected to internet?

It seems that Samsung Dive only works on my sgs2 when either the wifi or the network data mode is enabled on the device. What's worse is that if the "Wireless Networks / View Location in Maps" option is disabled, it will ask to be enabled while tracking the device.
Practically making Samsung Dive uesless.
Is there a fix for this? I've flashed a few ROMs but I'm back on stock, I never had this problem before flashing ROMs. Thanks.

I'm curious how you expect it to work without some kind of data connection.
Regarding your point about being asked for permission, if on KK5 at least, if you freeze the Network Location apk (com.google.android.location), the prompt does not appear and it does not seem to inhibit your ability to use GPS correctly.

Sorry if I made myself unclear, what I mean is that the user has to manually enable wifi or 3g to be able to use SD. So if the phone is lost, there's nobody there to enable 3g/wifi, so SD won't work.
You weren't unclear. How would you like it to communicate with the phone with no data connection?

Before I flashed ROMs SD would activate my 3g (when it was already off), then activate my wireless networks / location option, ten activate my GPS, then find my device. But now all it does is sits there, trying to connect, until i manually enable wifi or 3g, which it will then ask me to enable my wireless netoworks / location, and then it doesn't do anyting.
OP, you make no sense. You didn't answer to oinkylicious's question: how can SD reach your phone if it can't connect to it? It's almost impossible, so yes, someone has to be there to enable data or wifi. It was always like this and it will always be like this with the current technology .
About manually activating the tracking system, I also have my doubts. I only tried this several months ago, but then it showed my location without asking me to enable tracking. I'm on CM7 now, so I can't test it.
Alternatives: theft aware can do the same thing (now quite good, but it works) via SMS. You just send the code to your phone, and it gives you the location.

You still haven't answered my question. Also, could you provide some proof that this works on the other phone with all forms of data turned off, as it intuiges me.
If it works on an older ROM, revert until "fixed". If it doesn't, use an app controlled via SMS.

Knowing people who live on a council estate talking about disabling the internet on a phone or turning it off and flogging it on ebay leads me to believe different. That aware theft thing that works via SMS sounds a lot better

Hy, did you find a solution, i was thinking to register to samsung dive but found out about this problem. Does somebody really neads to turn on data manually for it to work? Thats just plain useless. If i lost it somewhere who will enable it, or if somebody took it i have to pray for them to enable data, lol.
P.S. Im also on custom rom.

Yeah I use theft aware, but you can get it free with the avast antivirus app. It's controlled by texts, and it has a lot more features than dive, wipe protection, etc.

Avast anti-theft is really nice. I'm using it also, but it's still beta, and has some serious bugs sometimes.
So back to your original question, I think we can call it BUSTED. There's no way for Samsung to activate data connection on your phone if it's turned off manually

T-Mobile Amaze 4g Software Update- WiFi calling included

Time to check for updates! Per tmonews.com, an update is available that includes wifi calling. I can verify that it does in fact include wifi calling.

Well I just went to check for updates and I see here that it says the update includes wifi calling and new sim card, so on and so forth.
Anyway it's downloading now.
Will report back once it's done.
Edit:
My phone has been updated successfully to version 1.43.531.3 and "Wifi Calling Feature" is now under Settings.
Except I have ER05 "Invalid SIM Card" which means I can't use wifi calling until I get the "new" SIM card.
Anyway that's the update!
Does this WiFi calling not handle WiFi to cellular handoffs? My phone says WiFi calling requires me to be in WiFi area all the time and my signal bars are null and have an "x" above them. Anyone else seeing this?

First you would need to unlock your bootloader.
Afterwards find a custom rom that you would want to install and put it somewhere on your sdcard.
Put the attached zip file in the root directory of the external sdcard (ie /sdcard2/PH85IMG.zip) and power off your phone.
Hold down the volume down button while pressing power.
You should see a white screen and it'll scan your sdcard then find the .zip file.
It should prompt you to update the recovery. Volume up to update.
Then reboot by pressing the power button.
When the phone is powered up delete the PH85IMG.zip file (or simply rename it or move it, your call. Just as long as it's no longer in the root of the sdcard.)
Now to get to recovery you have two options.
Download ROM Manager and select the Reboot to Recovery option.
Power off the phone again, hold Volume Down button, press Power to get to the hboot screen (white scree), select RECOVERY.
From this you can install custom roms.

Just like the old Wifi Calling, this one doesn't hand off. If you're on Wifi calling and on a call and you leave wifi area, the call will drop.

This happens if your service provider is currently busy (in some case during a thunder storm) that means you can only make emergency dials....
since when u have that issue
have you done something befoure that could have made your phone state this
in the settings of your phone you can choose or search for service providers
settings -> wireless and network -> mobile network -> serviceprovider
also check the option above the mode (2g 3g )
Try rebooting,that works for me

I suggest that try turning on airplane mode for a few minutes and then turning it off. I know it seems basic, but it should reset your 3G. It may or may not work depending on the phone and the service provider.

LGV30, Sprint, Won't connect to LTE network

I have an LG V30 with Sprint. Last week I noticed my phone wouldn't connect to LTE/4G network even in places where I know there is good service and other Sprint phones around me are fine. So right now it only connects to 3G and even then is mostly keeps going into roaming and won't go back to 3G until I toggle mobile connection on/off. I've tried just about everything I can do. Turned the phone on/off. Checked for updates. Toggled mobile network connection settings. Network settings reset. I even factory reset it and the problem persists. What very little I could find mention of this problem online mentions messing with the APN settings, but I'm not able to do that. For what it's worth the phone still connects to wifi just fine.
Any advice or help would be appreciated because I'm really lost here and it's becoming a real problem for my phone to barely connect to anything unless I'm on wifi.

What very little I could find mention of this problem online mentions messing with the APN settings, but I'm not able to do that. For what it's worth the phone still connects to wifi just fine.
Any advice or help would be appreciated because I'm really lost here and it's becoming a real problem for my phone to barely connect to anything unless I'm on wifi.

If you're on stock, reset your SCRTN
Open dialer and type in the following code
##72786#
It will ask you if you're sure you want to reset, click on yes
The phone will restart and it will go through the activating process and you SHOULD have LTE now.

Does this process wipe your phone to factory settings?

Nope, it just resets your network settings only. Your pictures, apps, music, and other things are left untouched.

SCRTN is a wonderful thing, solved problems for me many times when I was on various Sprint MVNOs.
But it only works with CDMA networks and phones (Sprint & Verizon).
For stubborn network problems on other non-CDMA models and networks I found the engineering/service menu factory reset to be a life saver. In particular did it solve a lack of LTE connection after a "partial" T-Mobile SIM unlock. To be clear, it loses the SIM unlock, which allowed me to unlock anew (and fully this time). Just be aware of that.
1) Backup everything, as the phone will be wiped. If yours is a network unlocked carrier model, make sure you have an unlock code (or unlock approval if T-Mobile).
2) Remove your Google account to disable Android Device Reset Protection.
3) Dial *#546368#*932# (replace 932 with your model number). This should open the service menu. From there SVC Menu - Factory Reset (R&D Only).
This takes quite a bit longer than normal Factory Reset. Your phone is now TRULY back to factory state.
While I haven't experienced any problems after doing this, I cannot guarantee that it is risk free or that there are no side effects that I just haven't detected.
So I would ONLY do this as a last resort.
