hi everyone. i m very new on this forum. i hope i can find a solution to my problem here. firstly i want to say i apologise for my poor english. my phone came from UK. it is a xperia Z2 D6503_17.1.1.A.0.402. i m using it in Turkiye. but i understand that the seller cheated me. the device is rooted and selled as original. my problem is that i can not use 3g(there is not 4g my country). i choose it from network mode as vcdma/gsm but when i choose the network signal turn off and the people cannot reach to me. if i choose only gsm the network signal comes and people can reach me. i tried to do reset but when i click the phone restart and a black menu screen (flash root screen) opened and writes CWM Based Recovery v6.0.4.7. as i mentioned i m new here and not a proffesional user. a friend said that my device is already rooted and DRM keys deleted while this operation and my 3g does nt work for this reason. is there any solution offer for me? thanks a lot.

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.
Hello everyone! I hope somebody can help me with my problem on my SOLA. As stated on the title on top I lost my Sim network Signal. The icon on top of the screen has been grayed out. It started when my SOLA was running a custom ROM SlimKat by alwaysadeel. I am not blaming the veloper but it goes like this, while the sola was on SlimKat I had this Advanced task killer pro installed on the phone. In the app, there is this FIX button at the buttom of the screen so hit it and then I started losing the Sim signal. I tired to hit that FIX button but nothing happened. Then I switch back to Stock ICS but the problem with sim signal is still there. Then I am seeing this "SIM not provisioned MM # 2 error" SIM that I tried to used during this issue are working/operational on other phones so I am definite that it is the device itself ha the problem and not the simcards. I even relocked my bootloader and tried fixing wigth PCC but I am so clueless how to fix it with PCC. If anybody has solution to this problem please I need your help. Thanks a lot.
Well, this is strange, you should be able to see signal after switching to stock ROM.
Assuming its a s/w fault.
anyways, first, the error means either sim card is corrupted or it hasn't been activated yet. Both are not possible in your case as we n=know they are working on other sets.
I suppose you are seeing this error AFTER switching to stock ICS, right ?
now, possible troubleshooting :
first, try CM, or again install SlimKat. After this you can try different kernels too.
second, check your ics release, it should be of your region, MT27a or MT27i, version should be right.
after downloading correct version, flash using flashtool, wipe everything.
hope it helps, as the problem is unique, i cannot think of any other possible solution.

I have a similar problem in a Xperia U, I've flash a CM9 rom like a month ago, and was working incredible, smooth, fast, everything ok, till this monday when lost signal, works ok with wifi, and also with data (at least in whatsapp, no fb, or youtube) but I can´t send sms or make a call, I've tried to flash stock (ICS) but the problem is there, even flashing just the baseband and the complete firmware with flashtool, I'll tried with GB now, but don´t know what else to do, when power on, recognize the carrier (for one or two seconds) then loose it, and when you search for networks, it say (Error al buscar redes) that an error ocurred, if you find a solution please share it, or if anyone have any suggestions, they are welcome... Thanks!!
PS. Can you believe it!?!?!?! MY own company have mi IMEI denied, I use a provisory sim card, FROM the carrier for a few days, while they changed my real number and gime my new sim card, to be able to change of company (carrier), then, a couple of months later, they discharged that "disposal" line and my IMEI went down with it, now I have to go to the office and solve the problem that they create me. Sorry, I know is offtopic, but I want to share in case someone else have this issue.
Hi everyone...
I'm from Mexico, so I sorry for my bad English.
I have a Xperia M4 Aqua and have problems with this.
When I buy it, flash to the latest version available at that time (E2363_26.1.B.2.102), then I did root and was running perfectly. But then I activate myXperia, after a few days I have problem to unlock the phone, then I read that I had to upgrade the rom (E2363_26.1.B.2.147 R6A_Customized Hong Kong) more than twice to clear it. I did it like that. The result was that disable myXperia, but I could not do root the phone. I was using the phone as well.
Two days ago, I had problems with the mobile Internet, I could not download the Internet settings again. What I did was flash again mobile, and now the problem that I have is that it does not recognize the sims. When I flash, turn off the "simlock" option from the panel "MiscTA Exclude". Is this the cause of the problem ??? The problem has a solution ???
Please, help me !!!
Thank you !!
