i had my first xda and was very happy to have one until this morning. i upgraded my 2002 to 2003 and setting it up for easy use.
while i was changing the phone settings i checked the 1900 north america network setting. and restarted my xda. untill then i cannot be able to use it as a phone because the network of my country is 900 europe.
i am trying to enter the phone settings but it doesnot respond.
can anybody help me to solve this problem? i am really locked right now...
Try to go to the GSM menu in the bootloader ... select the right band and soft reset ... you can get the GSM menu by pressing the Calendar button while in the bootloader mode.
Good luck ...
i am really very happy to have such an informative answer from you. but as i mentioned i am a new xda user and donnot have any idea of what the bootloader is.
can you please give me a detailed information of what i need to do?
all you need to know i suppose (know about getting in and out of the bootloader anyway )
http://wiki.xda-developers.com/wiki/ChangingBandsWithBootloader
the problem solved by your detailed helps.
thnk you all for your kind helps.
it is really nice to know there are some friends trying to help.
now i can use my xda...
Have the same problem - but still "no signal"
Hi
I have the pw10a device and had the same problem with my device after palying with GSM bands [tried to use in north america].
I tried all options in the bootloader both 900 and 900/1800 and after reset - it still do'nt wrok.
Can you help ? :roll:
so i bought a used vibrant off of a guy i know. And it worked perfectly. After a few days the phone just stopped working when i tried to do a factory update. Now the error i get when i try to make a call is "network not available" and where my bars would be it shows a circle with a line through it. I have tried booting on flashed roms and i have tried putting on stock 2.1, i have even tried to put the unlock code in, but nothing works at all!!! tmobile has no clue about anything and just keeps telling me to hard reset or send it in for repair but i have no insurance and i cannot be without a phone!!! please help me asap. i have also tried to go to select network and nothing comes up at all it used to say att and tmobile now nothing?? i am clueless here?!?!?!?! everything else works on the phone just no network as in wifi, market place etc. and i know its not my sim as i just got a new one and tried in my friends vibrant and it worked!
You might need to add the APN manually maybe?
Where you went to search network goto access point names and click on tmobile
The APN should be : epc.tmobile.com
MMSC should be : http:/ /mms.msg.eng.t-mobile.com/mms/wapenc
MMC should be : 310
MNC should be : 260
APN type should be : Internet+MMS
Just a suggestion but you could always just odin back to a factory fresh install. Sounds like the OTA update that you installed hosed something. Are you getting any SIM errors or anything else?
if u can (via wifi or something) download Rom Manager from the market and click on "fix permissions".... see if that helps.
all the settings in the apn are corect as per what the values you typed should be, i have rom manager and tried the quick fix with the permissions, nada, and this is the strangest problem as my sim card is reading as all my sim contacts are showing...so i know the sim card slot is not the issue, and when i tried to flash back to stock using odin 2x now, it still leaves out the calling feature, i was thinking maybe it has to do with the modem in the phone and somehow it got deleted for good unless i reinstall it???

This might be the fix you need. Download JFD tar and 512 pit files. It is a stock build that should completely clean and reinstall all the correct files needed. When you flash into Odin3 make sure repartition is UNTICKED or it will not work! I've had plenty of issues in the past and JFD has resolved every last one of them. J16 helps, but not with everything. Probably because it's just an update file.

What do you mean by it didn't work? The JFD file did not flash successfully or it did flash successfully, but you are still not getting a network signal? If no network signal then I advise you call T-Mobile and tell them you are having gps issues and they should replace the phone as long as it's still under warranty. It's worth a try. The worst they can say is sorry your warranty is expired.

the flash worked as in it was successful but no network still comes up. i called tmobile but since i bought the phone originally not from tmobile they said bring it back to the person you bought it from. tmobile even resent the signal to my phone and i was on the phone for over and our with them doing the same thing over and over, but to no avail. before i throw this phone on ebay for parts.... any other ideas???
ask the guy you bought it from.

did you check if airplane mode was on. i had it sometimes hide in the menus but never said in the notifications
So I checked airplane mode and nothing. It wasn't on that so still no fix. And the guy I got it from said he didn't do anything but I think he bsing. Is there anyone in the new york area that thinks they can fix this. Even if for a little fee it might be worth it?? Let me know asap I need a phone.
i guess no one found a fix for this as i still have the phone and the repair shop i got it back form seems like they didnt know what to do at all, even changed out the sim card slot to no avail.

Does turning flight mode on then off let it come back online? The issue is a werid one, but has been popping up around the forums. I wish I had a concrete answer for you. When you Odin back to stock JFD firmware, it replaces the modem entirely and should set you back to how it came from the factory. If thats not working, I would go get my money back.
Could you fix your problem with the phone? I'm having the same problem here. The weird thing is that my phone is unlocked and it works with an AT&T sim card, when I try my T-mobile card, I can't make calls. I tried everything, flash back to stock with Odin, manual settings, Airplane mode off and on, around 10 different Roms, and a bunch other suggestions but I still can't make it work. Any help will be greatly appreciated.....

Did you check these settings under Mobile Networks--AccessPoint Names? Do you see T-Mobile US as the selection? If you do, make sure the settings are as described here.
Flashing to stock would have fixed any issues that were software related... sounds like you have a hardware problem. You should odin back to stock.... wipe data/factory reset.... then flash again just to be sure. I've had funky issues that this has helped in the past

Problems are same for theese two problem.
1- There is no mobile network data. When i want to make call, it says, "mobile network not available".
I did the apn fix (set to default, reset etc.) No working.
I opened *#*#4636#*#* and do somethings explaning under "fixing network problems" threads.
Theese all not working.
I'm looking for help. This problem is not about sim card or operator(t-mobile etc.). Because a lot of people have same problem from all world. Every thidsd people using different gsm operators. So, fixing method with sim cards not working. This problem is about rom. Because, when downgrade to Android 2.1 or 2.2, there no problem. Please help.
2- Second problem is powering off it self every 15 minutes. All theese two roms have this problem. Not every time after 15 minutes. Sometimes after 10 minutes, sometimes after 40 minute (after boot).
2.1 and 2.2 also don't have this problem.
Please help.
There is a lot people on world using CyanogenMod. And they are flashing this rom with same method with rom manager.
Why this rom have problem about mobile network and powering of.

plz help me ...after the update everything is working fine but i dnt get the service....i mean the mobile network is unavailable....i cant make any calls...:'(
Did you try to make a complete reboot of your phone?
First of all are you sure you didn't lock you Sim code ? (try to put you Sim Card in another mobile and check that you can make calls.
If you have done this, check if there is an option that turn this servise of.
ics
On the ics beta for the photon you can go to the dialer and type *#*#info#*#*
Click on phone info and scroll to preferred network. Make sure cdma (prl) or GSM is selected if not change. Also note whether it says the radio is on right below that setting.
You might also try to go to airplane mode and back, or wifi and back.
If all else fails return to your stock backup and make sure all is well.

Guys I have a strange problem my razr wont connect to any of the data 2g or 3g only on custom roms like 4.4 Kitkat,Carbon rom etc . I flashed them on slot 1,2 even on stock slot but no luck.. I tried to change Baseband But It always failed So guys help me.....
Edit 11.12.2013:::
I fixed the problem partially..
I fixed the network mess It was bad radio which did this all I flashed ICS radio and now network works fine in all roms (Stock and Custom) BuT bo mobile data on any of them
Edit::::
Now Phone says NO SERVICE on both stock And custom rom but reads sim card contacts & SMS's...
I tried reflashing stock rom But no success. Help me guys...
2g/3g for many of the newer roms has been a problem with both the XT910 and XT912. I know with cyanogenmod 10.2 I'm still not able to connect to 2g/3g although LTE does work. With the newest release of cyanogenmod 11 though I do get 3g and LTE, although some people have been reporting they are not. Seems it's headed in the right direction. Give the latest CM11 build a shot and see if it works for you.

Is there any APN that saved in your network setting? If it doesn't, set it and save it by hand.

Can you make a call? Did you have paid the SIM card cost?
Sorry for my bad English
Yup my SIM is in contract and working on other phones I can make and receive calls but not on razr I get NO SERVICE message
Open the phone (or dialer, whatever you would like to call it) and Dial *#*#4636#*#* and go to Phone Information and tell us what the preferred network is.
--
Also:
What ROM did you get LTE Only on?
I learned that sometimes ROMs can mess up NV's. The only way of fixing this is to wipe everything and start fresh. And when you are flashing you cannot downgrade, it will fail every time. You may already know what I am telling you but just in case.
And what carrier are you with?

Hi. I have XT910 for more than two years. After brought the phone from Australia to Hong Kong (use Hong Kong SIM card) and back to Australia (replace SIM card with Aus one), I have the same problem as you. Phone can make voice call, but no mobile data connection (3G, 2G).
Want to know if your problem is fixed or not?

Hi. Can you tell me how to fix the issue: no mobile data, and phone saying "Syncing SIM card contacts"? Thanks.
So by a stupid mistake I have selected in *#*#4636#*#* the Radio Band to USA. The signal suddenly dropped and it stopped working at all, the nework does not connect except in 4G and only for data. Calls and text are not working, only 4G data works fine. This is on the sim1 though. On sim2 all is ok (except that with the X829 ROM, on sim2 I have no data, and on sim1 I have no calls )) ). I was on sim1 when I've changed the Radio Band, so I guess that only this one got affected since sim2 is working properly.
Is there any Radio Band files that I can restore? Or some app that can restore the settings of the modem?
Any help is highly appreciated.
PS: Reinstalling the ROM (clean or dirty) doesn't help. Factory resetting also doesn't help. I would downgrade to 014s but I'm afraid not to end up with a brick.
Change the rom

If i were you. I would change the rom from china to indian rom. It would help you. The radio band of chinese rom and the indian rom is different. It would replace the radio band of chinese rom and if it doesn't work. Then return to the chinese rom
I'm 100% sure it would help you.

I did the same thing by my mistake.And my le max 2 also became not able to connect internet. In my case, it can't connect both 4G and 3G .
But I fixed it. But I don't know that it get back to the original completely.
I'm japanese.And I'm sorry for that my English skil is very poor.
My current rom is Le2_X820-MAX_ROW-5.8.015S_V29_CUOCO92.
I used DFS CDMA TOOL and checked the items on the "Band Preferred" same as "RF BC Config".
1. download HTC Diag Driver. You have to customize .inf file later.
2. conect device to your windows pc and choose MTP and USB Debugging.
3. enter the follows command.
"adb shell"
"su"
"setprop sys.usb.config diag,adb"
When you enter this command, your device change over diag mode.
4. diag driver install.
You have to find hardwawer ID from device manager.
And replace the hardware ID in .inf file.
5. If you install diag driver correctly, you will be able to use DFS CDMA TOOL.
sorry, I can't explain any more..English is difficult...
I bought my phone from china and I'm in US, and it works perfect on stock with LTE enabled for AT&T by default. Might I ask why did you change it to US band and it stopped working? It would still work right?

Many thanks for the advice but it didn't help. I had installed the indian rom and then to the chinese without any change in the behavior of the modem. I'll try the chatmonchy's advice to see if there will be any improvement.

Actually I'm in Europe and looks like we use slightly different bands (??). I get 4G data but without calls. To other networks like 2G and 3G it connects sometimes but it's for few seconds only. I even don't remember what made me change the bands to USA, I guess I was curios what settings those were. The options are "USA band" and "Band 6", neither one is working well for my device. And strangely though, there is no other option to go back like "Auto" or something. It seems that I'm not the only one that did it. After a google search, it turned out that a lot of people had the same issue. For some, the factory reset helped, for others was flashing via TWRP the radio bands again.
I had solved the issue and I will post a guide later on for those who want to unlock additional bands or did the same mistake as I did.
Thanks for the help guys.

then after installation, go in dialer and call *#*#4636#*#*.
There are three band: Automaic, USA, and EURO.
I select the EURO and everything i'ts OK.

Unfortunately USA band selected
Hi,
I live in India. I bought Oppo F3 Plus (CPH1613) 4Gb Ram, 64GB Storage, Qualcomm MSM8976 Pro Snapdragon 653 a year ago and was working too much fine. I was wondering about Qualcomm mobile secret codes and found this *#*#4636#*#* . I dialed this and accidentally changed radio band to USA band and suddnly on instant my mobile didn't get any network signal. From then, I went for Oppo care, and mobile repairing shops and self tried and tested for lots of time; but everyone unable to bring phone to normal. I reset my mobile, flashed stock rom for countless times, wiped all data but nothing helped me out. Finally i rooted my oppo f3 plus and tried to boot in fastboot mode; but Oppo removed bootloader and fastboot mode from 2016 (as posted in XDA). I got a little link about resetting USA band to automate and is erasing modemst1 and modemst2. But again it have to be performed from fastboot.
Help me out for my mobile.
You can flash a modem file, it will reset it as well. Changing the ROM won't update the modem configuration. Try to search modem files and flash them via TWRP.
