Firstly sorry for my english, ı'm not a native speaker. I had a problem with my LUMA 3DS about its volume. It wasn't working so ı tried modding and other solutions ı have found but none of them worked. Later ı updated my luma and 3ds itself. Anywayafter update ı decided open up my 3DS. Pulled out first 2 screw then pulled out the battery and tried to pull out other 4 but ı couldn't, hence ı gave up and put everything back perfectly. Then ı opened my 3DS and luma settings came to screen. And ı wondered if ı change a setting from there anything would be diffirent. However something became diffirent and it became worse just by changing Hbmenu autoboot off to 3DS .After that when ı open my 3DS my dpad and touchscreen stopped working but my SELECT, HOME, START and XYAB buttons are working perfectly. Any suggestions?
