Samsung S7 edge stuck on 28% update for security patch

[CharlesJS]

Dear experts here.
From 2 days a new security patch is available for download over the air.
It was downloaded .
I pressed to install and the phone restarts and tried to install while on the blue screen .
The phone restarted before completing the installation and it reboot again and install and stay all the time till 28%.
I can't access the phone. ringtone samsung
It remains in the blue screen all the time.
Volume up and power and home doesn't work.
Is there anyway to remove the pending downloaded file to make the phone work again normally?
I need to access my data on internal memory before i make any factory reset to make backup.
Can I reinstall the same firmware on the phone without deleting my data.?

Any help please

Sorry to hear that. And it's a bummer to see you have had two posts go completely unanswered. Welcome to the Forum. Are you still having the issue, or did you eventually get the phone to boot up?
