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

1. backup via CWM
2. phone reset
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
Hiya.
The other week I fiddled around in settings on my Xperia Z1 (C6903). I was wondering about how priority of bands would look now when I got LTE too. So, I entered the well famous *#*# 4636#*#*, then "Phone Info", and had a look around. I opened the menu in there, then clicked "Select Radio Band". There's only one available, "USA Band", and I pressed it to check if something else appeared the second time around. It did not. Because the bands (frequencies) used in Scandinavia differ greatly from USA I lost coverage completely. Damn.....
I googled around a bit and there's not much information. Of course I could factory reset the phone, but I didn't want to really. One thread recommended reflashing baseband/modem. I erased data from com.android.settings, com.android.phone among a few others and did a reflash of baseband around that same time. Phone is working again, but I'm almost sure it's not fully back to normal. Loosing signal more easily now than I have before. I suspect I'm missing a frequency or something.
Anybody know where this setting is saved? Is it just com.android.phone? I can factory reset, but I much rather prefer to find out where it's saved. Somebody else might find it useful in the future perhaps?
Hej,
Sorry to reply to such an old message, but I just ran into the same problem. I clicked the "USA Band" expecting a list to show up. It didn't, and the USA Band was selected immediately. I no longer had a cellular connection.
Based on your suggestions, I solved it by issuing the following commands:
Code:
adb reboot bootloader
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot reboot
My cellular connection is back.
(OT: Now back to the problem that brought me in the *#*#4636#*#* in the first place: WiFi connected, no internet.)
Greetings,
after I lost on my xperia m4 aqua signal and couldn't connect to any network I went to *#*#4696#*#* and checked if radio is on and modified networks to GSM/CDMA auto (PRL), I got it back for some time, but after that it stopped receiving any signal again. While searching around in menus I selected USA Band (the only one in menu, thought it is OK to click it, as there wasn't even back button -.- ), it still didn't work. I read on forum some users lost reception after changing band. After which I proceeded by flashing original firmware (I relocked bootloader and used Sony PC Companion), which didn't solve my problem. The next step I choose was to flash modem.sin using flashtool from firmware downloaded through xperifirm (for my country, my mobile and same operator), but I still cant connect to any networks and when I try to find any, even tho my IMEI is correct, but I receive message: "Error while searching for networks". I am now completely lost as to what to do next, so I created this thread in hopes of getting assistance solving this problem.
EDIT:
My sim card is working in other phones, but in this phone doesn't work any sim. 1st I lost LTE signal only and could use 3G, 2 days ago only EDGE was working, but now I can't get any signal. I wasn't doing any modifications to system in-between. Does it mean my antenna is probably dead?
As i have no idea how to attach files, I put all of them to my google drive shared folder and here is link (spaces inserted, hope mods wont get triggered and delete it):
drive. google. com / open?id=0B1sZfIVuQbGqNnQ5SzVEUkF2R1U
includes:
phone infoabout phoneconfigurationvideo of error messagelog from booting into safe modein case something more is needed, I will try to provide it
I can't get the data connection to work at all, and it won't even connect to a 4g network even when the signal is strong. Mine is a H930DS (Joan?)
I just reinstalled the stock pie using "H93031a_00_OPEN_EU_OP_1105.zip", I installed in TWRP. I followed the instructions on the first page of this thread .....
I have tried various custom roms on this phone but this stock pie is one of the very few that even recognizes the sim card. I settled on stock pie inspite of the bloatware.
The problem happens when the rom is brand new, before ANYTHING is disabled or removed.
When I choose to search for a Network Operator (using the 3 Network sim) I get a "3 RAT-4G" and a "3 RAT-3G" listed and it will never connect to the 4G if I choose that one. It will only connect to the 3G. Even when the signal is very strong (5 bars). When I opt to connect to the 3G network then I get a stronger signal if I choose "GSM/WCDMA auto" in "settings>>network>>mobile netwroks>>network mode" but still no data connection
THESE DIDN'T HELP
1 - using ADB and restarting the phone in bootloader. It was to reset the modem I think. There was a series of 3 commands to follow. i can't remember the details of this method but I think one of the commands included "fastboot erase modemst2". I tried it and I was getting the same error message that other people reported and it didn't go anywhere.
2 - The following solution didn't work either..............
"re-loading IMS settings using the LG Hidden menu: Dial *#546368#*930# using the stock dialer -> Field Test -> IMS Setting -> Test -> Load Preset Configuration -> Initialize Configuration. Then back out twice to Field Test -> IMS Setting -> Test -> Restart IMS process. Give it a few minutes."
3 - Resetting network settings didn't help either (Settings -> General -> Reset -> Network settings reset).
4 - Changing APN, or network bands (in settings ... choosing "LTE/GSM/WCDMA auto" or "GSM/WCDMA auto" or "WCDMA only")
5 - Changing "set preffered network type" in engineering mode settings (accessing using *#*#4636#*#*)
How can I use data connection on my H930DS?
Data modem works now!
SOLVED!
My phone has bootloader unlocked and TWRP revcovery. That's obvious I know but I only say it again in case anyone tries this with a locked bootloader and using a stock rom that has never been flashed. (I have to warn you that your results will be different, your rom will be reset for sure an your data will be wiped).
I tried so many things, flashing up and down from 8 to 10 but Stock Pie was always the least buggy for me so I persevered with that.
I think this solution reset the hardware, but I am no expert.
The solution is basically a "Factory Reset (R&D Only)". They warn you against it but with my configuration all it did was reboot the phone into recovery and then left it for me to decide what to flash or wipe, as per usual. What I only realized later, when I rebooted into system (without changing anything in TWrP) was that it had reset the hardware, or reactivate data connectivity. NowI have 3g data connection and 4g connection.
THE SOLUTION
*the following 4 lines are a direct quote (my phone's os DID NOT reset)
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#*930# (replace 930 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.
I took out the sim and sd card before I committed to the reset. But like I said, it didn't wipe anything (maybe it would have wiped my sd card but I am not testing that). It just booted into recovery and when I rebooted into system I found that the data connection was working. Now finally it is a smartphone!
