Unable to unlock phone

Hey Guys,
I searched the thread but couldn't find any answers.
I got a Fido S4 (I337M) and tried unlocking it with the free method which didn't succeed.
I then paid FastGSM and that doesn't work either. Specifically, the client tells me it is unable to establish communication with my phone even though I have all the drivers installed and am able to use MTP with the phone.
The client pauses for a couple of seconds before responding with the error message
USB Debugging is enabled
Any thoughts?

Found solution.
Those guys don't bother telling you that you must have the SIM you wish to unlock in the phone.

Hi,
is that all you changed? I'm getting this error and still can't get a connection no matter what SIM I have in there...

Code unlock for the ls980

Hello everybody, I have the ls980 and it currently unlocked by the file changing method and I wanted to ask is there any way to unlock it by a sprint code or something like that? I know it exists because I did this to my old phone but at the carrier local store and I don't have a sprint store in Israel. Thanks

Problems with Samsung Galaxy A7(2016) SM-A7100

Hi friends,
I have a Galaxy A7(2016) SM-A7100 bought on Amazon and comes from Hong Kong.
I want to install a ROM with Android 10 or 11 and when I'm running Odin, I get this message on the phone:
Instalation Failure. You need to unlock your device to install a custom OS.
Do you know what I can do to unlock the phone and let me install the ROM?
Thank you very much for your answer
Hi, I think I have been able to fix the phone locking problem (I am not sure).
Now I have another problem, when Odin is doing the TRW download on the phone, it appears in red letters on the phone: Binary size is too large: recovery
After that the download stops and Odin shows FAIL in red letters.
What can I do?
