[Q] No signal/reception after rooting+flashing - Defy General

Hi guys, I have a problem again.
I just flashed and rooted my phone yesterday, went OK, so now I have CM9 installed on my defy plus.
The only problem however is that I do not have any signal/reception. By that I mean that I can't make any calls or send text messages.
I tried adding APN's, tried basebandswitcher (a couple, don't know the correct one for Belgium).
And now I'm stuck
Could u guys help me with this? Cause a phone wich can't call isn't all that fun

The baseband for Belgium is the same as England and rest of Europe. Normally this is only the problem when 3g is not working. Try to flash again maybe...wipe data... Try disable/unable flymodus. Reboot a few times... Disable Simlock.

I agree with the previous poster, but it's almost certainly your baseband that is not set up properly. I live in Canada, and the baseband that works with my phone is China. Do some research, trial and error, and you'll get the right frequencies.

I have tried nearly all basebands, none worked.
Is there a way I can go back to stock ROM? I tried installing a new zip file to SD card, but my pc doesn't recognise my Defy anymore
I also didn't make any backups

FIXED
I installed a new ROM, Kernel and Google Apps (still CM9 --> Android 4.0)
Thanks for helping guys

[Q] Crazy Johns/Vodafone APN settings???

Hi Everyone,
My Phone:
Lt15i
Baseband 70
Stock kernel with CWM
Arconium ICS
My Problem:
After going to a custom rom and kernel from a complete stock setup I cannot get a data conection on my phone. All other features work perfectly (Call, sms, wifi etc) just no 3g/2g data connection, or icon in the status bar. the Settings menu indicates it is turned on.
I have exhausted all available options regarding kernel/rom troubleshooting including a complete reinstall on the above rom/kernel. I also experienced this problem with other roms and kernels.
During setup I follow the setup app and download the apn settings for Crazy Johns (my carrier) and they report as being installed.
My question:
If anyone who is using Crazy Johns currently and has it working could please post their apn settings (text or screen shot whatever is easier) so I can compare these to mine and change as necessary.
Any and all suggestions for fixing this are welcome.

Yeah, tried getting it sent to me, entering it in manually, even tried entering various variations of it I had found on the net. Still no connection.
Everything worked perfectly when it was stock, and when i first flashed a new rom onto the phone (arconium 8.2 i think) it worked then too. but every rom since it hasn't.
I'm still quite new to this and my knowledge isnt too deep yet.
Could flashing roms or kernels effect the serial numbers of my phone or something and now my carrier doesn't recognize my phone?
I do still receive calls and sms...
It's got me beat!

Hmmm I think you phone is fine must be just the settings.
What does it say? Any errors? Can you grab a log too see if it says something there. Check my Sig for how to get logs etc.

Well props to you, you were right in suggesting it was settings related. I tried a different sim card from a different carrier and after following the setup procedure I had a 3g data connection. This of course means the problem lies with my sim card/carrier settings and not the rom or kernel.

[Q] Baseband version becomes unknown after restart

I'm using Droid Incredible 2 and facing a strange problem that I need help
My phone is using GSM network and rom Cyanogenmod 7 stable version
The phone works without problem until I restart the phone, the Baseband version becomes unknown and the notification shows the message "No service" so I don't have any mobile network
I tried to reflash the ROM and the problem seemed disappear. But when I perform a restart, I experience the same problem again
Is there anyone know how to solve this problem?

I would ask in the rom specific thread. You're more likely to get someone with experience with that rom to answer.

He can't post there most likely since he has only 2 posts. I had an issue with Viper like this but thought it was related to Hurricane Sandy....
One morning I grab my phone off the usb (computer) and it says Vodafone instead of VZW on the lock screen. Hmmm. Reboot and nothing changes. Can't send of receive texts or connect to 3g but phone works. I tried pulling battery, sim card....to no avail. As a last resort I wiped data and it has worked since with no issue although that forced me to re-install all my apps.
Hope this helps.

Thanks so much for your suggest. I wiped data and my phone works too. But I wonder what is the root cause of this issue? A problem of custom rom ???

[Q] Permanent no service - tried multiple roms...revert to stock?

HI all,
First post, go easy on me!
I've searched the forums trying to find the answer to this problem but have been unsuccessful. I successfully flashed my Galaxy W with slimbean 3.1.0 and had been using it successfully for over a month. I put it in airport mode to save battery, as I had done many times before, but this time when I turned it off the service never came back. I haven't had service since.
I have tested the SIM in another phone and it is working fine. I have also tried flashing a different ROM (CM10 Alpha 1) with no luck. I would reflash the phone with the stock firmware if there is any chance that would help, but I haven't been able to figure out how to do that via CWM. At this point I'm not exactly sure what to do. Is it possible that the this is a hardware issue?
Any advice would be greatly appreciated!

Yes it´s possible it´s a hardware issue you got after a while.
First thing I would try is to flash back to stock ROM and see if this fixes your issue. (With Odin)
There is a guide about how to do that, but am sorry not to point you to it right now. Its 4am here righ now and I already am having difficulties to write correctly. (need to go to bed soon )
If this helps I would suggest to update the baseband and then to try again with CyanogenMod.
But if reflashing the stock ROM doesn´t help either, I would suggest to contact the Samsung Service Center.
By flashing back to the stock ROM make sure you are flashing the one used in your specific country, because in the first place it also inculdes the baseband used in your country and in the secound place it also inculdes the country code Samsung might look at while testing your phone.
In Germany for example most SGW´s were sold with it´s specific coutry code. But there were also a few sold with the county code for the whole EU.
So you must care about such things when flashing back to stock ROM. For fixing it the country code is not important. Only the baseband used in your region is important. But I case you need to contact the Samsung Service Center it will be important.
Hope this helps a bit. Now I really need to go to sleep.
Does your IMEI number still ok? Cause I lost my Efs folder with IMEI number some time ago, in another Galaxy fone i had.
you can check it in Settings / About fone / Status / IMEI
If you lost it, you will have no service, no matter what rom you try.
In this case, you can try to repair using this http://forum.xda-developers.com/showthread.php?t=1308546 , not simple but saved my fone.

Mobile data not working +STOCK ROM

Hi everyone,
I have LG G3 d855 (Europe version). I bought it online, not at any network. I had an lollipop update really fast (Poland). Yesterday I rooted the phone, it worked fine, and installed the BlissPop rom. I missed the Quick Circle option though, so today I installed the ChupaChups rom for lollipop. And now my problem: The mobile data connection is not working. I can make calls, send texts, connect via wifi, but the data connection over the network is not working at all. I went back to stock - I downloaded and installed the European version using kdz method, it didn't help, so I did it over LG Flash Tool. It still does not work. Do you have any ideas, what to do with this? I feel like I'm going to cry, I'm very nervous about it, because I use mobile data almost all the time...
Maybe there's something wrong with the modem driver? I really hope someone is able to help me. Thank you in advance!
Edit: Maybe I used the wrong stock rom? I don't even have the option to update to lollipop anymore.

Seems like a modem baseband was flashed somehow.
Flash the modem back to the correct stock version you had and it should fix the problem

Do you know where I can find those modem drivers?
Edit: I checked which version of software I should use with my IMEI no. It's 20h. Would it be enough to flash the stock rom over kdz, or do I have to find somewhere the modem driver for this version? If yes, do you have any idea where can I find it?
Thanks.

Not sure.
I have the G2 and we have these files in our Development Section where you find ROM files etc.
Should be there as flashable zip files in the same section for the G3

Ok, thanks! Last question before I do the final step - I have the ROM I am supposed to have. I rooted the phone, installed TWRP. I've also found the modem driver for my rom. And the question is - how should I flash the driver? Should I mount system or do anything apart from just installing the zip? Should I clear any cache?
@CaPlanePourMoi Wipe the modem partition in Recovery and then just flash the modem zip which will replace it. If that doesn't work, you can go back to BlissPop that includes it's own Modem and install Xposed for 5.1 Super-Alpha and the QuickCircle Mod for AOSP, all 3 of those I'm using with no issues whatsoever!
So I installed the modem driver (20h) yesterday, but it didn't help. I decided to install the BlissPop ROM, and mobile data (with LTE) works just fine. I will go back to the problem on Saturday and keep you up to date. Thanks!
Update
Update: Hey everyone - it seems like I didn't find any solution. I tried to go back to the ROM based on stock again (it was Cloudy this time), but the modem still didn't work. It was acutally working for a few seconds (I had 4G connection), but then again it was lost and it didn't connect anymore. Wifi works fine. Do you have any ideas on how I can flash the modem correctly? And how can I uninstall the modem that I have now in recovery? I didn't do that, because I cannot find this option.
Thanks in advance!

I have a very similar issue
my LG G3 is the D855 on AT&T , and was working fine on Cloudy 2.2 or 2.3 Lolipop without any issues!
All of a sudden last Friday 5/22/2015, mobile data stopped working, but WiFi is still okay.
I just did a full wipe, updated APN, and the issue still there
I haven't change any major things in probably 2 months, not sure what's going on.
Finally, contacted AT&T, and made sure that they remove from the network,a put my back(troubleshooting). As well as changing the sim, and APN, but nothing worked!!
PLEASE HELP!!!!!!!!!!!!
UPDATE: So my last attempt, I contacted my provider AT&T, and they requested to try a default APN settings, even though what I used was working fine.
I did, and immediately my mobile data was back!!
Everything is working back as normal, and for some reason the network APN required updating
Did almost the same few days ago! I have finally solved my problem. Here's the explanation:
In Poland we had a network called "Era", a few years ago it was bought by T-Mobile. I searched the internet for T-Mobile APN settings in Poland and it didn't work. I have also found the APN settings for the old network, "Era" and surprisingly it's working. I don't know why T-Mobile settings don't work while they do for other people (and at this point I'm too afraid to ask. )
HI, i have the same problem on my d855 with wind (i'm in italy), i was rooted with custom rom and when i came back to stock i lose data connection. What i have to do? what do u mean for restore default apn? the default of my carrier? or the default for g3?
