I have a Verizon Trophy that has been GSM unlocked (I use it on ATT). After a factory reset, CDMA mode is my only option. I can't even find a way to enter the unlock code again. Is there a way to re-enable GSM mode? Thanks in advance for any help
nevermind. I fixed it by flashing a custom rom on it. I still don't know why it was only cdma after the factory rest.

Where you using a default Verizon factory rom? That's just plan weird. The default option should always be Global Mode unless the SIM Card wasn't seated correctly.
yeah it was the original firmware. It happened after a factory reset. The option under cellular settings would not change to anything other than cdma. it possibly could have been related to the sim card. Who knows? I guess it just gave me a reason to flash a new rom.

Hello. Tell me please what ROM you use to unlock GSM?
Thank you!

I did the software unlock via the dial code & UMTS menu, I can make phone calls with a different carrier sim, but I cannot get the data to connect. I have been searching xda and google for months trying to get this to work. I have a Canadian Bell mobilty i337m. Stock rom (mdj) and its rooted. I have tried factory reset several times but it doesnt fix it. I also tried flashing back to stock with odin. Does anyone have any other ideas?
When I try a telus (or other provider) sim, it give me voice service only and in the about > status menu the mobile network state either says disconnected or connecting. I have the data toggle on also.
Those unlocks don't work that well with the Canadian variants. They're designed for the i337 not the i337m.
Have you made sure the apn is set up right for the carrier?
Maybe this will help

I will say the reason that cause the problem is that this is an ATT phone with At stock ROM. So it doesn't have the APN setting for other carries. You should set that by yourself.

Not true. I successfully unlocked my first S4 I337M on Bell following this tutorial. I sold that one because I was able to make a profit once I unlocked and flashed the AWS mod to make it compatible with WIND and Mobilicity.

Try reflashing the original 4.2.2 firmware from here and then immediately follow this tutorial before rooting (do not install any system updates!). Then you can root, install custom recovery, reset the flash count, etc.

You did exactly what I am in the process of doing. I will try what you suggested now. Thanks!
Also, ive manually inputed apns for telus and eastlink and neither seem to work. I can always make voice calls, but the data will not connect.

oddly enough, when I put a telus sim in it and waited for a while (in hopes it would eventually connect to data) and the apn settings for telus were in the phone. I know I didnt put them there because the apn settings for koodo were also present along with a third apn that I cant remember.
For future reference, try not to double post. Just edit your current post.

It's actually not an odd thing to happen. Once an activated SIM is inserted and the phone is unlocked, the phone searches for the best APN settings from all compatible carrier bundles. Some phones do this more accurately than others. However, it may not do this well enough if a custom ROM is installed. I know this to be true because this happened with my older Galaxy S3 when I tried selling it to someone (it was a T-Mobile unlocked running CM 10.0 at the time). However, setting the APN manually (assuming all settings are correct and that nothing else is wrong with the phone) should resolve your issues.
If you're still having problems, I suggest doing these things:
1. Try going into your network operators and let the phone search for carriers nearby. Once the list shows up, tap on Telus and wait until that screen closes on its own.
2. If you can't get data going yet, try disabling it, re-enabling, and reboot.
3. If this still doesn't work, try going into the network mode screen and select GSM/LTE and reboot.
4. If it's still derping on you, then it must either be your SIM not connecting to Telus's data network, or your account has a data block. That's all I can really think of.
Good luck.

Ok, reflashed stock 4.2.2 (the first one) and manually entered TELUS apn settings from the telus website, got data to connect finally. As a note, there was a typo in the apn settings that it auto aquired for telus. Going to try a eastlink sim tomorrow and hopefully AWS is working.
Edit: all seems to work. thanks everyone!!

Well, I had the same problem with my s3. I did a factory reset, and it worked. Try flashing the stock rom again, and be brave because you might lose your phone from not flashing right.

check your apn settings for your provider
i check and edit the apn setting n now data works perfectly but wifi still doesnt connect... i dont get it
try turning airplane mode on then off
you don't say if you are rooted with any custom recovery/rom or your build version
I have the D801 (I think that's it, the TMobile variant) and unlocked it to take it over to AT&T. We had to change the APN settings to get it to work of course. I am now wanting to sell the phone but would like to know if the Unlock still sticks, and if the APN settings were reset back to the Tmobile/stock settings?
The phone hasn't been rooted or anything of that nature, just the unlock code when I took it over to At&t.
Thanks!

The unlock will remain but the apn settings will most likely need to be re entered. I have the opposite situation(at&t d800 that I'm using on t-mobile)and I have factory reset this device and did the upgrade to kit kat and the unlock remained. I did have to re enter the apn settings after both the reset and the os update.

Excellent, thank you very much for the information. I wanted to be able to be a little more informed on that stuff before I try to sell it in case they ask. Appreciate it.
Hey guys
I was out shopping tonight and the weirdest thing happened to me. My data stopped working. I realized it when I was trying to make a phone call.
I toggled airplane mode on and off "nothing"
Power cycle "nothing"
Reset back to factory settings while on pure nexus rom "nothing"
Unrooted and flashed stock factory image and you guessed it. Still no dice.
Weird thing is that when I put my sim card in my note 5 it works fine.
When I put my wife's sim card, she's with another provider, in my nexus 6P it works with the exeption of LTE. For some reason when I put another provider's SIM card LTE doesn't work.
I bought my phone off of Kijiji so I'm not sure I can call google for an RMA.
It's just weird that my sim card work fine with another phone and that another sim card works on my phone.
I'm stumped guys.
Any suggestions?

Yes the radio is in the factory image, if you did it manually it's possible you forgot the radio.img. If you bought the phone used it's possible it has been reported stolen or the previous owner stopped making payments. That's all I can think of, also make sure your APN is absolutely correct for your provider.

It was working just fine until last night. I flashed the whole factory image, radio included. It works with a SIM from a different provider. No LTE though.
I have an unlocked version that I converted to verizon by changing the CID and flashing the stock verizon RRU. For some reason I cannot activate advanced calling on the device. VOLTE calls will not work as well. My SIM is from a VZW s7 edge with advanced calling enabled that works fine on it. When i swap the sim to the HTC and go to the advanced calling it wants me to activate then says it is already activated on my account but will not make volte calls.
Anyone have any suggestions? I've reflashed etc. Removed advanced calling etc. If i removed advanced calling from my line, then try to activate it on the HTC it gives me an error and wont activate through the device. I assume because its not in their system.
Can i force on VOLTE? Should I have put the sim in later or something?

Remove it from your account. Factory reset the phone after a fresh ruu. Then activate from the phone and the phone only.

Should i factory reset from inside the OS or from the bootloader? And also should I leave my SIM in it the entire time, or after ive got it set up and booted to the OS?

Boot loader. Since the sim is already provisioned leave it in.

I had no luck with the methods above. I even went into the store, the issued me a new sim. I told the guy about the phone and how it was unlocked but It had the official VZW software. He helped me out but we could still not get VOLTE to work on the Unlocked version of the phone. We tried removing it from my account and readding etc. No luck. Looks like I'm just going to return it and maybe buy the VZW version and have Jcase s-off it/bootloader unlock it.
Have you tried putting the sim back in the old phone and turning advanced calling off from there?
