hi there, my atrix does not want to register at operator.
My phone was always trying to use 2g cause of better signal.
I went to Admin menu (*#*#4636#*#*), changed to WCDMA preffered, but in about a minute it did not change. I tapped function key and then Select Radio Band, it was only USA - i tapped it.
So he do not even try to register at any operator.
but i can call 112.
there is no any band other thsn USA.
Our band are almost same
900/1800/2100
So at least some operators must register.
may be i can refresh the modem part via bootmenu?
Or is there a way to reflash the modem part?
thanx

3. restore backup.
Hi friends,
i was playing around with the title code of this topic.
After entering *#*#4636#*#* in my x10,i selected phone information,pressed the physical menu key on left of phone,than clicked "select radio band". In that there was only option under the "set gsm/umts band" which read "usa band".
I selected that and instantly lost network signal. I live in india and the phone is of usa at&t unlocked.
Now i am not getting signal. I tried to press the menu key again but it reads "usa band only". Tried to manully select network,but no luck.
Finally i also did factory reset,wiped cache partition,reflashed my wolfbreak rom ,but could nt get signal.
What else can i try?
is there any one who can help?
IS there anyway to rollback to original/default settings/bands?
any chance that there is a restore, or similar button inside that menu? Have you checked this?

Okay, here's the fix - I found this out because I did EXACTLY THE SAME (curiosity killed this particular cat!!) and PRESD BUTAN (USA Band) without thinking, on my Japanese X10 (SO-01B), which, as you did, set my phone to the wrong band for Japan. Duh!
Anyway on to the fix...
1) Bring up the service menu with *#*#4636#*#* at the phone dialer
2) Select Phone Information menu
3) Switch the phone to FLIGHT/AIRPLANE MODE (I did this by dragging down the top menu bar on my phone which is running a custom rom)
4) Press the menu key and SELECT RADIO BAND - you'll see the complete list of country bands - do NOT select a band yet....
5) Switch FLIGHT/AIRPLANE MODE OFF
6) Select the country Band you require - you should now see a success message.
7) Congratulations on getting your cellphone signal back
Regards!

hi, does erasing the modemst mess with the phone's communication functionalities? some forums are reporting problems after erasing the modemst (http://forum.xda-developers.com/moto-g/help/sim-status-erasing-modemst-t3160579) but it was on a different device. I'm on lenovo zuk z1, and having the same problem. I would like to try this solution out if it does not mess with the communication functions.

Hi Brother,
I'm facing the same issue on my Nexus 6p in India purchased from USA. Do you have any solution to deal with this problem?
Thanks.
Omg! I posted this in 2012 ? After 5 years still people are facing this issue! As far as i can remember i had to reflash stock Rom to get it back to normal. Thanks everyone for replies
I am kinda new at this but I have tried many roms and there gsm fixes and I cant get any to see my sim card or switch to gsm mode I am in Sweden. I have tried different cm9 ics also miui ics and and fallowed there instructions and tried there gsm fixes but still nothing any ideas?
Thanks
did you flash the kddi radio?
Have you tried:
Type *#*#INFO*#*# into phone dialer.
Select Phone Information.
Select GSM auto (PRL) under "Set Preferred network type".
Not sure if those are included in the instructions you mentioned, but GSM network settings are hidden in some ROMS if GSM isn't selected in the menu above.
Hi all
I have P768 and i'm having an issue with radio. I flashed JB from South Africa, everything works great.. at least in begining. Randomly my phone stops receiving calls, text messages, data connection.. It's like my phone became an ipod
So, i assume the problem is my radio, i tried flashing back to ICS to see if baseband in phone's seetings became different, but unfortunatelly for me, it is not changing. I offline flashed euro 20b, ics, but my baseband is not changing (System settings > About phone > Software information > Baseband version > L6260_MODEM_SIC_01.1230.00)
I want found a radio.zip in carlos thread, but it is for P769. I dont want to flash that because i can lost radio permanently, since my phone is not changing that in offline flash.
I'm wondering where can i get those files, i have JB P768 kdz, can i extract the radio file from that and flash it via CWM into my phone?
I already tried switching radio file (LGP768.fls or something i don't remember now), but it dont change either.
I think the only way is with CWM i don't know, but if someone could help me, it'll be much apreciated
Hi shucrut,
To this date, the only method to change radio (baseband) of L9 is through KDZ flashing (online or offline, whatever).
If you flashed KDZ and think the baseband has not changed, what is happening is simple: the info in System settings > About phone > Software information > Baseband version doesn't change, well, at least in several versions of KDZ (ICS or JB) I flashed, the Baseband info was the same.
But, there is a best place to check baseband version: in Hidden Menu > Version Info > Factory Version.
If you flashed a KDZ changing the baseband (*.fls) you will see, Factory Version reflects the baseband.
For example, if you used a KDZ of V20B Australia changing the baseband by LGP768.fls of V10B Claro Brazil, you will see: LGP768fAT-00-V10b-724-05-AUG-26-2013 regardless of the version of KDZ.
Hope this helps.

Thanks for repplying. The thing is that for Brazil they not updated P768 to JellyBean, so i'm on the way to flash JB on this, because ICS is too much slow in many situations..
I will try to explain what is hapening and if you could, please, help me figure this out.
My network provider is Oi, it operates in frequency 1900MHz for 2G and 2100MHz for 3G. Another networks here uses different frequencies, one is not compatible with another, so the phones here need to be quad band (850, 900, 1800, 1900), 3G (850, 1900, 2100)
So i flashed already many roms and can tell some experiences i had:
- MEXICO JB: Everything working normal, except for 3G: I think LG disabled the 3g working in 2100MHz on mexico roms, so i have not 3g
- SOUTH AFRICA JB: Everything works, including 3G . The strange thing is that after a day using it without rebooting the phone, i simple lost carier signal, so i cannot receive/send messages or calls. In this state, my phone shows me i do have signal, but nothing works.
--- I tried switching the radio.fls from many roms to see if this problem disappear, like Brazil's ICS radio, mexico radio, europe, p769 v21 radio.. The problem persists after every test
--- Strange thing is that sometimes took me a day to lost signal, but sometimes took me less than 2 hours
- VIETNAM JB: same as SOUTH AFRICA
- EMIRATED ARAB JB: same as SOUTH AFRICA
So this is my situation, i'm stucked with a locked bootloader and ICS due to this carrier's signal problem..
I dont know if LG disabled something in these roms that dont use some frequencies.. After some search, i found this:
http://www.worldtimezone.com/gsm.html
looks like some countries do use 2100MHZ for 3g, but still gives me that problem. I don't know what else i can do
Sorry for late reply, I've been busy the last days.
So, did you flash a KDZ (Mexico, South Africa, Vietnam, etc.) switching the baseband in the middle of the flashing, right?
And the version of the baseband is showing in Hidden Menu > Version Info > Factory Version?
Did you make another modifications (like changing rild or lge-ril.so)?
I also tested several JB versions (Mexico, Australia, Open Europe, etc.) with the ICS Claro Brazil baseband and didn't notice any abnormal behavior (radio related, of course; the roms have their own bugs:silly.
But maybe the difference is in the methodology. When "nothing works", if you switch (off-on) Airplane mode, makes any difference? Signal strength is showing in status bar? After reboot, the phone returns to normal?
I will try the same versions (Vietnam and Emirated Arab I have not yet experienced!), but now my bootloader is unlocked, and my provider is Claro BR.
Hi,
Following a tips in an android newsblog (In France), i was visiting the *#*#4636#*#* menu.
By curiosity, I tap on the menu "Sélectionner une bande radio" (choose a baseband).
I've only a "United States" choice but after did nothing. I lose all my phone network.
Just the data work and the sms.
What can I do to this ?
I think to flash a baseband firmware but where can I find one ?
Thanks for everyone who could save my phone

Switch your radio band back to automatic? Go to *#*#4636#*#* and click the overview (3 dots) at the top right. Hit select radio band, then hit automatic. Reboot phone.
Thanks but no auto option for me :/
I've done a Factory reset but no change.

I try to put network in Only 3G or 2G and got nothing. Maybe that's why there's no call but sms and data. No VoLTE in France.
When selecting United States band (that I didn't want to do), i break the 3G and 2G connection.
Hi,
I've speak with the Motorola support in France.
In the hidden menu, i've selected the united states band so now I only received the LTE (the only which are the same than here). No 3G and no 2G.
And because We've got no VoLTE, I can't use calls.
And no method to revert this process.
Go in warranty...
Actually there should be a way, because I have the selection:
Automatic
Europe
Automatic
United States
You probably have to update to a current stock ROM so the modem firmware updates and you might be able to select a different baseband... all theory but if you still have the phone, it's worth a try.
edit: I'm using a custom ROM, so I may be wrong.
For you there is no way of using a custom ROM without having problems with warranty.
If still relevant, I made the same mistake with my stock Moto xt1650-03 and the only way managed to restore signal was by using fastboot erase modemst commands. Though I have seen people not recommending this method, it worked for me.
