Galaxy S7 SM-930F - looping on logo

[Members_fnjcsFu]

Hello, 

This evening, I've deleted pictures on my phone and it suddenly froze.

I tried a reboot with "Power + Volume-" and it stays on Samsung Galaxy S7 powered by android for a long time.

After that I always have light blue screen with "Installing system update" and then after few minutes I have a black screen with these lines:

#Fail to open recovery_cause (No such file or directory)#
#Reboot Recovery_Cause is [UNKNOWN]#
No Support SINGLE-SKU

File-Based OTA
E:failed to mount /efs (invalid argument)
Supported API: 3
E:failed to mount /efs (invalid argument)
E:failed to mount /efs (invalid argument)
dm-verify verification failed ...
E:failed to mount /cache (invalid argument)
E:failed to mount /cache (invalid argument)
E:failed to mount /cache (invalid argument)
E:Can't mount /cache/recovery/last_locale

When I do "Volume+  + Home +  Power" nothing is happening. I cannot have the SAMSUNG logo thingy.

It seems also that I cannot power off the device.

I have also removed my sd card.

Any idea how to fix that issue? 

Thanks for your help.

Hello,
please have a look on YouTube as it helps. I had a similar problem and it fixed. For deleted pictures it should be on ur recycle bin.

I already looked over a lots of video etc, I cannot enter in Download mode because the manipulation to do so is not working on the first screen..

Thanks but I cannot access the bin since my smartphone is looping..
