Sir here's an advise
Check one of my thread and follow the steps on page one, please Restore your iPhone and set it up as new iPhone then download Beta 3 and then try to update your Phone.
If the Wifi being grayed out dissapears it means that the IOS that you've downloaded nor loaded to your IOS isn't the internation IOS, how to find out if its a hardware issue? User your mobile data if and inch below the camera lens should be warm(hardware issue) when you use your Mobile data for more than 30minutes, but if it doesn't it is the incompatibility of the IOS. Feel free to try.
boss iOS7beta3 ako.. hardware issue to...
freezer for 10mins works only for 5min..
hairdyer below the jack (back) hanggng uminit (or 5 min) na hindi mo na kayang hawakan works, mga 2 days lang.. lagi ko tong ginagawa..
UPDATE doesnt work, restore doesnt work, downgrade to ios 6.1.3 doesnt work..
pag lumabas ios 7 at hindi parin to naayos, repair ko na tlga to.. (me idea kayo kung mag kano?)
base sa nbsa ko, reflow daw ng logic board kelangan.. wla akong idea dun... nabsa ko lng..
This is a hardware issue, when you upgrade your phone is using all it's resources. umiinit ang board and capacitors, so mga mga unit na tinatamaan tlaga ung wifi and bluetooth ic. swerte ung mga hindi nasiraan ng unit after updating. khit na i downgrade upgrade mo eh wala nang mangyayari jan. kaya ung iba ang solusyon is blower para mainitan ang i.c and umandar ulit. pero after ilan mins mawawala nanaman.
Actually may magaling na nag aayos ng iphone. khit yang greyed out unit naayos nya. One time dinala ko ung ip4s ko na na water danage ayaw ng bumukas. after 1 hour nagawa nya hanggang ngayon 6 months na nagana pa din. and sa comments sa kanya ilan na din nag pagawa sa kanya ng greyed wifi naayos naman nya
sana online kapa.. san mo pinagawa yang wifi mo ska mag kano?
eto pakinggan mo ts.. sa firmware yan, pag grayed out na ba yung switch nung wifi hardware na agad? ano naman kinalaman nya dun? diba dapat hindi lng sya gagana kahit naka on ang wifi kung hardware ang sira nya? so malamang you need to clean restore your iphone sa itunes..
nang yari naba sayo to? i doubt na alam sinasabi mo.. hindi gagana yang restore mo..
bakit siya gumagana pag nag babago yung temp? sobrng init o sobrng lamit? naapektuhan ba FW dun?
