Here's my story, about 3 weeks ago i bought my new xperia SP, and first i get the sim card provide by some operator that include the package. And for some reason i have to change the sim card for another operator, but after i change the sim card the signal seems low then the first operator. And i try to get some information about this android phone. And i get this some information that give some advice about setting the signal. And the good thing about it is it can make the battery can last a little longer because the setting set just choose the wcdma only or just gsm only it depends what the best in my area, and can reduce the heating that cause from device always search what the best network if we choose the wcdma/gsm option. And here the thing start. I follow the instruction: first you dial *#*#4636#*#* and the setting window come out. And the choose phone setting, set the network to wcdma only or gsm only. And i choose the wcdma only. After that start to refresh the smsc and update it. After that the instruction said to choose to select the radio band. After i select the radio band my device loose the signal and it just show x in signal bar. After that i try to restart the phone but it come out the same no signal appear. I try to remove and replace the sim card but it steel same, i try to change with another sim card from another operator and it steel same. After that my last choice is to reset my phone to factory setting. And seems it work my signal is back. But after that my phone signal become so weak and recently i got my signal got lost for a view time it just show x but it's not for long the bar seems back again. I start confused is that the advice i choose is wrong ? And there a some info that i got from some search in internet that says upgrade the baseband can make a risk that wifi, LTE signal, and the other connections setting loose they capabilities. I'm so frustated now need help immediately, anybody have some advice or solution? thank you first.

I've been facing the excat same problem with my Xperia SP (C5303)....
Please, can ayone help us?
Thanks.
I have the same problem too. I go to the service menu then select the USA band, and I lost the signal. And there is no networks found/available!
The solution is, you need to flash the baseband. First you need to download the newest stock rom (the stock must for your country, you can try asking Google). After that, you download and install the flashtool ( ask to Google too ).
After that, install the drivers (not compatible on Windows 8.1 ), goto C:/FlashTool/Drivers, and run the installer, then select Flashmode Driver.
After you install the driver, move the downloaded rom to C:/FlashTool/Firmwares, then run the flashtool via start menu.
Click thunder icon, select Flashmode, then select the firmware you downloaded.
Make sure that you only flash baseband, not kernel or wipe data, or anything (I forgot where the checkboxes located)
Then, click flash. Turn of your phone. Then hold Volume Down Button, and plug the USB cable that connected to PC, until the illumination bar turns green.
Then wait the process, and it's done.
I hope this helps you

that solution is for you accidently choosen the wrong band, and you lost the signal forever. If they are having low signals, try switching from WCDMA to 3G

Ok, sorry for not giving details earlier. I've been using my XSP for 6 months on a 2G connexn, and all was good. Then I tried to shift to a 3G and my problem, on WCDMA only or WCDMA Preferred, I get absolutely no connection, no voice, no data, no bars! GSM only for 2G is still fine. Wifi is working fine.
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.

kk but still i have no luck getting 3g on newer versions too.
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.

thread: [SOLVED] Accidentally changed the Radio Band to USA
Hi, gyus
I had the same problem, i select USA band and everything went wrong,
The simplest way for me was:
installing "X820 LeMax2 RevolutioN_Team Resurrection Remix", no other from TeamSpain, only Resurrection Remix
http://revolutionlemax2.blogspot.al/
https://mega.nz/#!T9o0wAhJ!iLa9mrPAr...VkCg3_L-q2RgnA
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.
BEFORE DO ACTIONS DON'T FORGET TO BACKUP ALL THE ROM WHERE YOU ARE WITH TWRP

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.
I have one Jio Sim and one Idea sim. If I select cellular data on the Jio sim, both sims have network. However if I select cellular data on Idea sim, jio does not get network. Is this a known problem? I am using the CM13 Snapshot with CM13 firmware. Any help will be appreciated!

Use Jio Sim in SIM 1 slot, i recommend you to flash modem files from MIUI 8(MM), The radio firmware which comes in Firmware.zip is buggy doesnt works in many devices such as mine. So i have to flash MIUI modems everytime when i flash CM and after that it works like charm.

Just download beta rom form MIUI, and extract NON-HLOS.bin file, and flash it in fastboot mode. dont restart the device, just switch airplane mode on and off, your network will be back.
This phone supports LTE + LTE standby. I think it means only one sim can use LTE at a time. Correct me if I am wrong.

U cannot use LTE+LTE, Jio being a All time LTE Network as soon u choose data on any sim be it on 1 or 2 the data shifts to LTE for the sim selected for data changing the band for network on the other simcard.
@Rohit DK donnot flash any modem it will not work. Also u might get problem with sim cards not detecting.

ohh.. i just forgot that JIO is all time LTE network, but flashing the modem files from stock rom will not messed up in anyway. @Rohit DK yes he is right, i literaly forgot that JIo is all based on IP network, so if you have cellular data turned off on JIO, Its still works on IP.. so yes you cannot use jio sim with other sim data on.

let me simplify the language for you to understand maybe it might seems stupid for others, but i will try my best , JIO is all Data network, which means when you are not using its internet. it is connected to the internet, because it works on internet only, all calls, sms, everything works on via data connection only.. if you see 1 bar in network strength, it is connected via Data only, This is what LTE is. right now phones are not capable of connecting data on multiple sims at a time. so by this logic.. Your jio sim is connected to internet by Default(doesnt matter cellular data on or off, it is connected to it in both cases.) so when you manually trigger the cellular data on 2nd sim, JIo sim goes offline, because your phone is configured to connect data only on one SIM. huh..

Bro my problem is not jio, its airtel
Same problem
Same problem here. I m using one plus 3
Hi, I downloaded and installed Lineage ROM, everything was working fine but I found that I was not able to send text messages (receiving messages was okay), I tried change values under test menu (*#*#4636#*#*) but problem persist.
I tried clean installation of new ROM (Aosp).
I tried install new firmware from:
https://forum.xda-developers.com/re.../firmware-xiaomi-redmi-note-5-5-plus-t3759683
And baseband from :
https://androidfilehost.com/?fid=746163614322262750
And finally, text messages are OK, unfortunately I am not able connect to 4G/ LTE networks now. Only 2G and 3G networks are working. LTE services were working without problem on original Miui and Lineage ROM.
Can someone try help me how solve it ? I would really appreciate any ideas.
Do you think this can help?

Thanks in advance and happy weekend
i have the same question! +1
I tried fresh install original MIUI ROM, but it did not help
http://en.miui.com/getrom-340.html?m=yes&mobile=2 .
LTE is not available still.
I did not try this method still: https://androidfilebox.com/app/redmi-5-plus-modem-firmware/
But I don't have another option I guess.
With LTE no Problems = https://forum.xda-developers.com/redmi-note-5/development/rom-omnirom-t3823189
Unfortunately LTE is not working on this ROM (Omni) for me too, but I expected it, because as I wrote I tried original MIUI as well. It's problem of wrong firmware, baseband, modem or something, because hard reset or flashing new rom don't fix it. Btw, this morning I was in big city in my country and my phone was able connect to LTE, but it was 1800 or 2100 MHz, which are available only in bigger cities. When I came back to home, it showing only H+ again. It seems my phone is not able to connect only to LTE on 800 MHz (B20) currently, which is most widespread LTE frequency in my country and this one is only available one in my location. And I was able connect to this network before. Unfortunately I don't know how I can bring it back.
Solved.
My friend share her .xqcn file with me (she has same phone) so I flashed modem file via QPST Flash Tool to my device. Xiaomi started receiving LTE in my location- B20 frequency band, unfortunatelly it was continuously connecting and disconnecting between "no signal" and 4G.
The next step was flash MIUI 10 Global Beta ROM 8.8.9 to my phone via Miflash. LTE seems be stable and fully working now.
