Hannspree Hannspad SN1AT75 HSG1310 firmware

Hello I'm New here, I hope someone can help I can't find any info on my tablet but this thread seems to be the closest. I'm looking for a stick Rom for a Hannspad SNA1T75. It says HSG1310 on the box. I have some issues with getting into recovery mode too as there are no volume buttons on this model just a power button and a home button. If anyone can point me in the right direction for either problem I would be very grateful.
