I unlocked my sprint sgs4 and am using a sim card in Australia.. its now on FSM and not CDMA.
can I simply flash any i905 ROM and then just a sprint kernel? does that make sense?
I no longer need any of the sprint network customizations being that's I'm using a gsm sim card.. anyone?
I have a cdma phone unlocked for gsm but I did a rom reflashed, is still unlocked?
Hey all,
My 900V is currently running CyanogenMod 13.1. I am unsure if the device is unlocked or not as it was a floor-demo model. I do not have a SIM for the phone and I plan on converting my old AT&T SIM for use with the phone. I would have to unlock for this, yes? Or will switching to Metro render my current SIM useless?
Hello,
I have a S7 930P that is GSM unlocked.
I flashed 930U firmware.
When I put in GSM sim, it says "Invalid SIM"
Am I suppose to lose unlock?
If I flash back to 930P, would I get GSM unlock back?
I left Sprint and now on GSM network.
Please help!
I obtained an XT1766 (Qualcomm) with build NCQS26.69-64-11 from an mvno called Tello (aka Sprint). The state that all the phones they sell are unlocked. The SIM say Sprint on it. When I asked if I could use it on a GSM carrier they said it is only CDMA compatible.
The XT1766 spec clearly shows it is GSM capable, and Sprint themselves state that they can unlock the phone for at least international GSM, and US GSM after a set amount of time.
I installed a GSM SIM, and the phone report "Hidden Menu" Invalid SIM.
My questions:
1) Is Tello in denial that the SIM is unlocked? It seems GSM locked to me.
2) Does this phone have an Android build created by Motorola that disables GSM?
3) Is the only way to enable GSM is to unlock the bootloader and install custom OS?
4) If the phone is "locked", the Motorola will not give a key to unlock the bootloader. Correct?
5) Can this CDMA sprint based phone be used for other CDMA carriers such as verizon?
Sorry for all the questions. I am new to how these things operate.

Can't use it on gsm anymore. The new update locked it up tight. You can still unlock the bootloader. But custom ROMs aren't going to help. They closed that hole right up.
What is the build number that locked up the GSM function?

Either -08 or -10 were the end numbers of the build that did it. Can't go back either. It set an efuse. No amount of downgrading can undo it. It's been tried. To the point of bricks. Sorry bro.
No longer works for domestic unlock if you have late 2018/2019 security updates. You can only unlock it for foreign use

AFAIK no foreign either. Feb 2019 wont lock the device to sprint but it wont unlock you with C.Roms. Jun 2019 will lock the device and no way to unlock it to be used either in the US or outside. Just Sprint by now.
Again... As far as i know. Correct me if i'm wrong please.
