Your problem is that your CSC is still ATT, it should be XAA.

Ummmmm...Rogers is GSM and the Verizon Galaxy Nexus is CDMA. You can't change it. You can't use a CDMA phone on a GSM network. You can't do it with any Verizon or Sprint phone (besides their global phones). The phone is useless to you. The GSM model ships factory unlocked.
Thanks for your reply, this phone is really confusing to me because unlike all CDMA phones it still accept micro-SIM card. and in network mode it asked me to select LTE/CDMA ..could you please tell me why it is saying LTE ?

Verizon uses LTE technology as well.
so this one is CDMA for sure and it will work only on verizon ?

Well I haven't seen a picture of it, but if it says Verizon on the phone, then yes, it will only work on Verizon.

[Q] Nexus 5 D820 works only on 2G

Hi,
I bought a new device, Nexus 5 D820.
And I have a problem when I insert SIM regardless of which provider I have no reception (no service),
Tried to set the correct APN settings with the provider but it didn't help.
It works out only when I'm working on 2G when I return to 3G again no reception. (No LTE in my country)
what could be the problem?

The D820 2G and 3G should work in my country, just without LTE support.
D821 also should work includes support for LTE.

Did you enable 3G in settings/More/Mobile Networks/Preferred Network? Do you have 3G coverage in your area? Tried with another simcard if you can receive 3G? Tried a data factory reset or reflash the rom?

Data factory rest or reflash the factory image in fastboot, if that doesn`t help and your APN settings are correct i would RMA or claim warranty for the device, but first you could contact your operator/provider if there is an issue with their network near you or maybe you need a new simcard.

I found that the IMEI inside the back cover is not the same as the IMEI outside.
I tried to flash other radios - didn't help
To flash custom ROMs and 4.4 stock - didn't help
When I'm switching to 3G I can't find any network when I switch back to 2G it still not finding any network but only after restarting the phone the 2G is working.

The IMEI is different because your phone most probably stolen or because fo human mistake.
Maybe your operator does not allow your phone to connect to 3G networks.
I get my nexus from austria before it got released in my country. I had LTE until my operator started selling nexus 5 too, and from that day I don't have LTE.

Same problem here...anyone?
Well, depending on your operator, 3G frequenties used maybe not the same as the ones uses in China.
I know that USA LTE(4G) isn't the same as here, in France (If not I would have bought it in USA for 349$, that equals to 255€. And I bought my N5 349€ in the play store)
Try to call your operator and ask them for the frequenties they're using ?

i have problem with my data connection. when i set the preferred network to WCDMA only and LTE only. my phone has no signal at all. i have a strong 3G connection on my other phones.
is it a baseband problem?
if it is. how to flash the correct baseband for my F350L?
or this maybe a hardware problem?

I see that you are from Manila and using a F350L please check supported bands by your network and the supported bands of F350L if they are compatible.
i did check it and it is same bands use here. there are f350L users here with no problems using their 3G connection.
My F350L is LTE-8 other F350L are LTE-A. I suspect that this two have different band
I am having the same Problem up here in Ohio
No matter what I try I can not seem to get this phone to do anything besides just G I am running the F350S on AT&T
Please look in Dialer with 5457#*350# and activate your Bands
Still no dice

Hi folks, I am Nigerian and I use an LG G Pro (D838). Some days back i noticed that i had no network on my phone so I tried inserting another sim into the device and still got the same result but other devices around had network coverage. I changed the network mode to GSM only and got 2G but WCDMA only gives me nothing. I have tried other sims on GSM only mode and got 2G but when i change the mode to WCDMA only, i get nothing at all. Have also put it to GSM/WCDMA auto but keeps giving me just 2G network only. I have even had to downgrade the OS from android 5.0.1 to 4.4.2 as suggested by a friend and still got the same issue. Please, what should i do??????
Same problem overhere Lg g pro 2 though F350k
I have the same problem in Holland. I have the F350k variant) 3G is in Holland 900/2100. The phone has despite of the advertisement text !!! by selling (900/2100) 850/1900/2100. The 2100 band is the same so should work.
Tried a lot. By the way last software and Androi 5.0.1.
The Sim is not the problem, the APN setting not, ........
any suggestions?
Could it be somewhere oleh software??????

Hello, I am from Nigeria.
I bought my LG D838 on eBay in May 2015 and was quite impressed with the performance but my pride and happiness was short lived. I woke up one morning in December 2015, and noticed I didn't have any cell reception. I checked with my siblings and I seemed to be the only one who had no cell reception on the same network as theirs.
I swapped SIMS of other networks into my phone but still to no avail but funny thing was that whenever I change network mode to 2G only, I get reception but switching back to 3G only mode gave me nothing at all...this happened a few days after I updated the OS with a 50MB patch file using OTA as prompted. I have been writing to LG since then but no reply and it has frustrated me so much as I bought this phone for about USD 398 and didn't even get to use it up to a year. I managed it on 2G while trying to contact LG about it until the Wi-Fi and Bluetooth stopped responding also. I need the NV and QCN backup file for this phone in order to get it running again…I would really love to see this beauty run again. Please help me out.
You can contact me or send the file to [email protected]. I am open to suggestions.
Thanks in anticipation.
