No Network after flash

Hi,
I successfully rooted my Nexus S 4G and flash it with with the gingerbread-ns4g-deck.
Everything worked fine so far. Mod looks great.
But I do not get any network service after the flash. It seems the phone is not recognizing the SIM card at all. Normally it asked for the PIN number after a reboot.
Now it doesn't. Also I have no option to choose a network manually.
I tried flashing different basebands (radios) and kernels.
Still no chance.
Thanks for your help! I live in Germany and have a Vodafone contract by the way.
All the best
GB

Nobody with an idea on this one?
Is there by chance an option where I can activate the SIM through entering my PIN number?
What should I do (install) to at least go back to the original firmware?
Thanks in advance.
GB

Thx for your help

Dude... you need to read more...
This is for the Nexus S 4G... for SPRINT. You flashed a SPRINT CDMA ROM on your GSM PHONE.

No problem man. It's pretty hard to brick these phones, I've even seen someone flash a CDMA radio on a GSM but they still fixed it... not that I suggest doing that!

Help! Stuck Wifi

I just a new G2 yesterday, and was trying to find some way to transfer over my saved wifi passwords from my old phone to my new phone.
I found an app on the play store which looked to have good reviews, and it worked backing up my passwords from my old phone, but attempting to restore them on my G2 seems to have broken something.
Wifi does not turn on at all now. It is stuck in "Turning Wi- Fi on"
I reluctantly did a factory reset (twice) and this did not solve the problem. My next step is to flash the stock firmware, but my browser estimates 5 hours until it finishes downloading... (100-200 KB/s)
Any idea of what I can try in the meantime? Thank you for your help.

What carrier are you on? I'm no expert, but maybe you can find the radios and flash them instead. The download would be much smaller I think.
Also, your Google account should back up your Wi-Fi information as well. When I got my G2 and logged in, all of the hot spots I've connected to in the past were already saved.

I'm on AT&T. I didn't know that was possible, but that would be nice, so I'll look around.
Thanks

[Q] LS980 No 3g data on AOSP ROMs

Hello!
I have Sprint LS980 flashed to Intertelecom Ukraine (EVDO Rev. A) by the NVram.
The problem is that i don't have 3g data connection on AOSP roms, it's just not connecting.
I have data on every stock base Rom and Omni Rom.
Any ideas? Thanks!

Same here. Just flashed my first AOSP ROM (Carbon) and I'm getting 1X instead of 3G at home. Is there a way to update PRL or Profile maybe? Thought it was a ROM specific issue.

Tried to edit build.prop but get no luck to get data work.

Unfortunately on some ROM it's not active , on other one there is no such pass. When i use aps that open that setting aps crashes.
Always thought that NV programmed phones have no need in APNs.
Thank you for trying to help me!

so im assuming this phone is CDMA? i don;t know as im british so i don't have all this complicated stuff and simply just buy a GSM phone and it works on every network. I am just basing my answers on my on phone.

Yep, it's really a CDMA operator (EVDO rev. A is CDMA) and LS980 is Sprint version of LG G2.
And everything you wrote will work on GSM, but any way thank you for trying to help!

[Q] Galaxy S4 (SGH-I337M) says NO MOBILE NETWORK (HELP!)

Hey guys,
I'm new to the forum so please excuse me if this is the wrong place to post this. I'll start from the beginning. I bought a Galaxy S4 (SGH-I337m) from somebody in my city. They said the phone originally worked with Rogers/Fido, but that they switched the logic board on it so now it works with Bell/Virgin. The thing is though, when I put my Virgin Mobile sim card in the phone, it won't let me send texts or make calls. I checked the IMEI and it's not blacklisted or anything.
It says No Service and has the little circle with a diagonal line showing up in the notification bar and when I try to send a text, it says No Network Connection (No signal found for mobile networks). I find it weird because I still get a notification saying that I have an unheard voicemail.
I've tried resetting the phone multiple times. I've also tried flashing both the Bell and Virgin Mobile Lollipop firmwares and that didn't work either. To be honest, I'm not sure how to tell which one I would need to install. I noticed when trying to flash the Bell firmware, that the phone kinda skips to a black screen quickly every time I close an app. I'm assuming that would mean it needs the Virgin Mobile firmware.
That still doesn't fix the mobile network issue though. If anyone could help me out, I would GREATLY appreciate it!!!! Here is a bit of info, I'm hoping it helps. If you need anything else, please let me know.
Model number: SGH-I337M
Android Version: 5.0.1
Baseband Version: I337MVLUGOC4
Build Number: LRX22C.I337MVLUGOC4
Also, in the "Status" menu, I noticed it says:
Service State
Voice: Out of Service / Data: Out of Service
Not sure if that has anything to do with it or if that's normal. Again, if you have any suggestions, PLEASE let me know. I'm super desperate as I can't afford to lose the money I paid for this. Thanks in advance.
EDIT: Coincidentally my girlfriend has a Galaxy S4 of the same model and with Bell/Virgin. I opened up the ABOUT DEVICE menu in both phones and the only other difference I noticed is on hers it says:
SE for Android Status:
"sepf_sgh-I337M_5.0.1_0013"
And mine says "sepf_sgh-I337M_5.0.1_0009"
Does that have anything to do with it maybe?

Install this APP and add all screenshots pls .

Okay, will do. I will post the screenshots in about 20 mins. I rooted the phone, installed CWM and am in the middle of flashing the latest firmware again. I forgot to enable USB debugging before flashing originally and I wanted to install CWM to wipe the cache. No idea if that would make a difference but I've been up all night trying anything lol. Thank you for the reply though, will post the screenshots in about 20 mins.

Okay, I have the app installed. Which screens should I screenshot? I know you shouldn't post your IMEI online, so I'm assuming I skip the "personal" tab or?

Here is 4 of the screenshots I took (I hope this works lol)

Here are the other 2 I took

All seems correct but I think your device works for Bell Mobile (BMC) only but NOT for Virgin Mobile (VMC). Try to use one BELL simcard for verify it.

In all my experience, Bell/Virgin are always interchangeable. Same with Telus/Koodo and Rogers/Fido. I tried putting a Bell sim card in though just now and it still has the problem. It doesnt load any of the signal bars or anything. Oddly enough, when there is no sim card in the phone, the bars show up?

Since it was from Bell, would flashing the Virgin Mobile firmware somehow mess it up? What are the exact steps I would need to take to try to reset it back to stock settings? I'm wondering if I'm missing anything. Or if the APN settings have anything to do with it? I set them to default already and tried adding the Virgin Mobile Canada apn settings as well

http://forum.xda-developers.com/galaxy-s4-att is the proper place to ask your questions regarding your S4, rather than where you originally posted this, the International S4 forum.

Lost LTE after PIE

Hello guys.
I have an issue since I decided to flash a pie rom, specifically simplix blue, have no idea if has something to do with that rom.
I used to have LTE as normal and everything was good. Since I flashed a PIE rom I lost LTE. I tried going back to stock and LTE is still gone. Had tried flashing some modems, did not work either. Tried several radio combinations on *#*#4636#*#* did not work.
Any suggestions? I am on Tigo Colombia as carrier and never had this issue before across several xiaomi devices that I have had

Nope.
I had found a solution already. It is kinda long so tomorrow I Will post a guide. For some reason the band 4 that was the one that my carrier uses was blocked. So I had to unblock it
I have seen several people here with similar issues and not being able yo Solve it. Hopefully the tutorial that I Will make, help them as well.

Yep, I have been quite busy, as soon as I have time, I will post a tutorial. Meanwhile, take a look at this post, read first part of post 3 and then post 7.
https://forum.xda-developers.com/lenovo-p2/how-to/enabled-4g-ca-p2-t3707584
As soon as you finish adding the band, install network signal guru, provide root admin rights and then select on the 3 dots at the top right corner lock bands, select lte and pick up the band missing and reboot.

Also facing this, I'm waiting for tutorial.
