Inkpad 3 Support and Repair

Follow up on Inkpad 3 Issues -- The seller of my Inkpad 3 informed me that my warranty is only 6 months and my problems started after the warranty expired. Pocketbook Int. has been good with communication but not very helpful. It surprises me that they do not even offer a repair depot and my question is: Where are the authorized or unauthorized repair depots for Pocketbook e-readers in particular or e-readers in general. Even Goodreads where Pocketbooks are now sold did not offer an option for repair.
The status right now is that my inkpad 3 will only operate when connected to power. The battery is showing a high state of charge -- obviously, since it is always connected. I did update to the latest firmware but that actually made its operation less smooth -- I now get the system file error again so I will go back to the original firmware, less stops and starts. One last point. If the power disconnects and it shuts off, on restart it takes me to the first time run or setup -- language, wifi and all that. If the battery is fully charged and it 'remembers' all the settings, would it restart that way?
Does anyone know how to disassemble the Inkpad 3 or have a link to this procedure? I have been looking but cannot find -- usually if it is there youtube has it but so far no luck.
thanks,
