My mom has a Samsung S7 and it suddenly turned off with the blue light staying on steady. When I try to push the power button to get it to turn on it was a black screen with tiny blue letters that said recovery booting. After that and acted as if it was installing something with that screen that says initializing system update. That is followed by a screen that is blue has a warning sign in it and says no command. What the heck can I do cuz I've tried everything I know how to do from trying to from trying to start it safe mode with the volume down and power button and then I even tried the home screen button power button and volume up button. Help please we can't afford to get her a new phone right now.
Thanks for reaching out for assistance.
I can understand the frustrations this may have caused you.
Can you send a private message providing the full model code and IMEI of the device so I can look into the warranty status? http://bit.ly/2GGYul4
