I have spent the last two days trying to transfer from my 'original' kindle all my books on it to my Amazon Fire 8 which I have just purchased, to save me taking two tablets with me on holiday.
Can anyone please help me.
How are you trying to 'transfer' the books? Content isn't transferred between devices. Were all the books obtained on Amazon? Once the new Fire Tablet is registered to the same Amazon account which has the books currently on the Kindle E-reader, go to ALL, select the titles you want to DOWNLOAD to the new device. Another option is to go to the Amazon website (Your Account > Content and Devices > Content), select the desired titles and DELIVER them to the new device using 'Actions' (...).
