You have one of the many VIA 8505 Tablets. These are low power/priced tablets. It is difficult to recommend what firmware without pictures or detail of the firmware number. This will help others recommend the correct firmware. Look in the VIA sub forum for potential assistance.
Hi. Pictures are the same like on the site i put. But on my Epad are small pictures on the side with speakers. I think original rom there was 188.8.131.52. but i am not sure. I download "original" 184.108.40.206 rom but without success. First screen (unlock screen) I had "Slide to unlock" . When i have a lucky and i find working rom, my touchscreen and buttons doesnt work.
