Getting parts for this S4 Zoom is really a pain, so parts4repair.com came really handy.
The guy at the repair shop told me it was not a 'guaranteed repair' due to heating needed over the main board (it was a 50/50 chance the phone could end up useless). Luckily, everything went out just fine and now I have the phone working flawlessly. Fast shipping, cheap price, great part quality. Thank you!
