I'm trying to unlock my sprint htc one m8 with insertcoin rom.
I copied the modified apk to /system/app (but there wasn't ant htc odman speck apk already there) I gave all of the permission reboot ant went to sim unlocker app. I got to the menu press sim lock, after that i've gat a message Vdm cilent isn't responding. Do you want to close it? After that i've pressed OK, and I get this message: "Sim Unlock appears to be successful! Please reboot now."
After the reboot I'm getting the message : Invaild Card - Please contactt customer care
I've checked 2 nano-sims which are both 100% works on another sprint m8 I have.
What could be the problem?
