Unhappy [Q] EFS Backup

Hi guys
Guess what? Yes that's right I have a corrupted efs folder from a bad flash, and my back up has disappeared from my PC. I've searched via Google and directly on xda and am aware that there is a proposed method to rebuild the efs but the tablet needs to allow adb access which I cant do as it wont boot past the boot logo and i apologize now if this has been asked previously and I've missed it. I've had numerous Android devices and flashed custom firmware on them all including this tablet so im not a complete novice when it comes to sorting them out however this time im struggling. So im throwing the following questions out there to see if you can help:
I can enter TWRP and Download mode

A: Does anyone have a backed up EFS that i could flash via recovery (is this possible/allowed due to it being a tablet and not a phone)?
B: Is it possible to force the tablet in its current state to allow ADB access?

Your Help will be gratefully accepted

As far as I know, EFS contains the serial number as well as other device specific info so someone else's EFS might not work. If you can boot into recovery, adb should work then. If not, use Odin to flash the latest @Android-Andi TWRP recovery and then adb should work.

I can get into twrp but have not been able to get adb access, I am aware that there is a way to rebuild the EFS if this can be done(would you be able to provide assistance?) I have tried refreshing both original and custom rooms but all get stuck at the Samsung logo as I belive the boot sequence looks for the EFS info at that stage.
