Hi, probably you used a tempereture too high, maybe the wifi ic is in short now...
Check first if the wifi is working now.. if not, tou have to replace the module
Every time i open this guide, i see this message "This guide has more recent changes"
If you read my comments i always says that is not a permanet fix but can work for 2 days or 2 month or 2 years.
Anyway if someone spent time and money for buy the hot air station, he can spent also 10€ and buy the new wifi Ic and replace it.
But a 4s logic board cost 40-70€ so is stupid buy a new hot air station.
This is a solution for every user who wants to try to fix using a screwdrver and a hairdryer.. if this not work you have to bring the phone in a professional center who can fix it PERMANENTLY
Tou can try it again. If not works, you have to replace the motherboard or the wifi ic
I wrote this guide for who wants to fix his phone at home. I repeat, this is not a permanent fix!
If after rhe rehot the wifi is still grayed out, you have to chiange the wifi ic. But is not simple to do this at home.
The mostly 4s after a rehot works forever. The same thing is for the lg g4 bootloop, rehot the emmc make the phone works again.
I usually offer 2 solution. X3 rehot for a small price, or i change rhe ic for the double price.. so the customer have this 2 option.
And they always prefer the first option...
You have first to try a new screen. Maybe you damaged the flat of the lcd.
If the new screen will not show the image, you have broked something on the motherboard. You can figure out but is not simple to fix a motherboard if you dont know what are you trying to do.
Anyway im pretty sure that you broked tour lcd
hi, nope, you dont have to reach 200 c..
reflow it again staying on 185 celsius.. maybe reflow for 10 minutes but always under 200 degrees
thanks, im happy you solved with my guide.. remember is not a permanent fix, but is the best solution to do at home
hi, i think that on 500k users that have used my guide, maybe 2 or 3 have no fixed the problem. anyway this guide is made by me, a professional fixer that have 2 shops where me, and my team, fix about 30-50 phones per day..
we have all schematicts, and all solutions for fix any kind of problem, and i decides to share our "secrets".
this guide is the easy way to fix this problem at home, is not workin 100% but the method is correct..
if you read all the guide you can discover that this is a semi permanent fix, the right way is to replace the chip, but without a professional machines is impossible to so, and is very hard..
sorry for my english, im italian
if you have any question, im here for you
best regards, Andrea
I think yes but the wifi chip is a little bit harder to find. Is under the shield. You have to desolder the shield and reflow it. Check first if there is any antenna disconnected
I dont think so
