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!

What happens is I flash the wrong firmware to a verizon s5 such as att or Tmobile?

I want to be able to use my straight talk att sim in a verizon s5.
Will it work if I flash the att firmware?
No. Do Not flash a variants firmware to your verizon phone or you will end up with a $600 brick.

You can use your sim WITHOUT flashing other firmware. Verizon 4G phones are sim-unlocked, so put your sim card in, change APN settings, and voila.
Hello, I am rather new here. I am trying to sim unlock m Galaxy S5 (sprint) that I bought on craigslist. I have the unlock code from Sprint and a Tmobile sim card but when I insert the tmobile sim it doesn't ask for the unlock code, instead just displaying "invalid sim". This is an unmodified phone, not rooted or anything, a stock SM-G900P. Thank you for your help.

Common scam from Sprint customer service... they gave you the SPC code for that device. it does not SIM unlock your device. To unlock your device, install the Sprint Samsung Unlocker APK. This will allow your unit to work overseas only, not in the USA. SSU.apk link?

I am looking to enable GSM on my S5, which is currently carrier locked to CDMA. it does have a sim slot, but the carrier the phone was made for locked it to CDMA. it's a G900R7. My device is rooted, and uses TWRP.
I unfortunately locked my unlocked S8+ international version while trying to flash the CSC for T-Mobile and now I can't use my sim card and I have no idea exactly where this phone originated from... am I screwed?
