There is few steps missing actually.. But I did't wrote them down, sorry. Nevertheless, they are pretty common sense. ;)
ps. Actually this is second time I did that repair. Just after the first one, after a while wifi went down (bluetooth still were working). So I did those steps once again and wifi is up and running. Again.. :) Yiiiihaaaa!!! :)
ps1. my rework device Yihua 8786D when set on 300C by Thermo reader showed only 150 or so, but that reader also is Chinese crap so I don't give a dime that it's wrong. Anyone tried measure that? Should it really blow set temp?
