Sorry dear ... I posted how to fix your tablet but? Because I included a link as to where to find the part you need? They marked my reply as spam. Apparently this site is run by morons. Long & short of it? NO you do NOT need to solder anything!
Do a search on youtube (again, sorry, I am not allowed to include the link) ... there are several videos on how to do this. And your sd card reader is paired with the vibration moter. You can order one off of ebay. Just look for a company with a high rating. Again? Sorry but? This site does not allow me to provide a link to help you. ...
Whsts the sense of having a help forum if you cannot provide people with the tools they need yo be helped? Aye "ifixit"?! .... unreal
