Steps to Factory Reset most (if not all) Samsung tablet:
Now your device should come out of the Android Boot Loop and at the first time the device will take some time to reboot.
If these steps still don't work then you may need to restore the software on your tablet via Samsung Kies. If I can remember you do it via Tools > Firmware upgrade and initialization. This will prompt you to enter the model number and the serial number of the tablet which is usually at the back of the tablet or in the battery compartment.
If the Samsung Kies method does not allow you to download the firmware for your tablet then you'll have to go to http://www.sammobile.com/firmwares/ where you type your model number of your tablet to find the firmware for your tablet . Make sure you choose latest version to the network it was mainly with.
Samfirmware instructions (After the file has finished downloading):
My tablet is as good as dead, it doesn't do anything just black screen, battery reads 3.9v tried disconnecting and holding buttons down etc but nothing, ive replaced the charging port but stil no joy. I can buy a new motherboard would this fix it? Would it need the firmware loading on etc?
