Introduzione
La scheda madre è il cervello del tuo telefono. Potrebbe essere necessario sostituire la scheda madre se il telefono presenta problemi importanti. Prima di iniziare, potrebbe essere utile consultare questa pagina di risoluzione dei problemi per diagnosticare i tuoi malfunzionamenti.
Attenzione: se sostituisci la scheda madre, il tuo dispositivo perderà la sua impermeabilità. Dovrai sostituire la guarnizione impermeabile se prevedi che il tuo dispositivo possa bagnarsi nel prossimo futuro.
-
-
Prima di iniziare, spegni il telefono.
-
Applica un iOpener riscaldato su uno dei lati lunghi del telefono per ammorbidire l'adesivo sotto il vetro posteriore. Applica l'iOpener per almeno due minuti.
-
-
-
Nei passi successivi, taglierai l'adesivo che fissa la cover posteriore.
-
L'adesivo deve essere tagliato nelle aree evidenziate:
-
Parti dove l'adesivo è più spesso
-
Parti dove l'adesivo è più sottile
-
Evita di far leva o tagliare in questa zona per non danneggiare il cavo flessibile del sensore impronte digitali.
-
-
-
Fai aderire una ventosa alla cover posteriore.
-
Solleva il bordo inferiore della cover posteriore con la ventosa per aprire una sottile fessura tra il vetro e la scocca.
-
Inserisci un plettro di apertura nella fessura e fallo scorrere fino all'angolo inferiore destro.
-
Inserisci un secondo plettro di apertura e fallo scorrere fino all'angolo inferiore sinistro.
-
Inserisci un terzo plettro di apertura per evitare che l'adesivo possa riattaccarsi nel corso delle operazioni successive.
-
-
-
Inserendo soltanto la punta del plettro di apertura, fai scorrere l'attrezzo lungo il lato dall'angolo inferiore sinistro fino alla parte superiore del telefono.
-
Fai scorrere il plettro attorno all'angolo superiore e lascialo in posizione per impedire che l'adesivo possa riattaccarsi.
-
-
-
Fai scorrere il plettro di apertura, percorrendo il lato del telefono, dall'angolo inferiore destro fino alla parte superiore.
-
Fai scorrere il plettro di apertura attorno all'angolo e taglia l'adesivo rimasto nella parte superiore del telefono.
-
-
-
Alza con cautela il lato del vetro posteriore dalla parte dei pulsanti del volume.
-
Usa l'estremità di uno spudger per sollevare e scollegare il cavo flessibile del sensore impronte digitali.
-
-
-
Estrai la scheda SIM utilizzando un dispositivo di rimozione della scheda SIM o una graffetta dispiegata per premere la leva di rilascio.
-
Per rimontare il tuo dispositivo, segui queste istruzioni nell'ordine inverso.

Are there any issues with replacing the motherboard in phone sold for one region, such as the SM-G960U, with the motherboard for a different region, such as the SM-G960F?
Salve. Se non funziona il bluetooth wifi e connessione cellulare. Bisogna sostituire la Scheda madre?
Nightmare. Impossible to get the back off so far. Being trying using the iOpener with hair dryer for last 1hr. No chance.

You’re right Chris. I’ve tried on 3 separate occasions now and haven’t been able to budge that back. All that has happened is the pick has taken a piece out of the glass back leaving a rough edge now.

it was not easy but doable.

It’s difficult, but the trick I did to get it was to wrap the hot iOpener around a bottom corner, apply the suction cup, then I covered the opener and phone with a paper plate, better insulating the area. Then I set my blow dryer to high heat and low velocity and heated the area under the plate for about a minute. Right after turning off the blower, I took off the plate and pulled the suction cup with a cutter at hand. You’ll hear a bit of a cracking/popping noise when the adhesive is starting to give, just apply a little more force and push the cutter at the seam. This method worked great for me, so good luck and just keep at it — you’ve got this!

I used nearly boiling water in a storage zip bag on the phone for 10 minutes. I can’t really recommend this method, but thankfully the bag did not leak - an iOpener is probably a much better way to go. Regardless, the bag covered the entire back of the phone, and the phone was too hot to hold, but I still could not get the glass to budge with the suction cup after struggling with it for about an hour and multiple reheats. I ended up epoxying a 2”x2” square of PVC board to the bottom of the cover and built a relatively complex fixture that pulled on the PVC with the turn of a screw while it held down the frame by the edges. After heating the edges up again It did lift the glass enough to get a pick underneath it, but it cracked the glass and it was a pain to slide a pick around the edge while the glass was cracking all the way around. Once I finally got all the glass off, I spent the next 30 minutes (which is what this entire process is supposed to take… what a joke!) cleaning the adhesive off the phone.

Well, it is not obvious how to do this. I have no iOpener, but a heat cushion for remedy hurting muscles and sometimes a backpain. It is filled with grain of some kind and it is to be heated in a microwave oven for about 3 minutes. After that I enveloped this cushion round the phone and brewed myself a cup of tea. After ten miutes the phone was warm (almost hot) and I was able to press the tip of a small (very small) knife above the charging port into the connection between the phone body and the backplate. A very small opening emerged slowly (this is the critical point in this process) and I was able to start using the iFixit opening picks. It became obvious to me that the opening picks are too blunt to achive this with them. But after starting carefully with the (very small and very sharp) knife, everything went straight forward. Thou I had to give the phone a second heatpush with my heat cushion before the backplate came loose.

I used my 3D printer heat bed and heated it to 90 Celcius to succeed.

It took about 3 minutes on my 90 C printbed to get the first pick in. If the suction cup gives up before the adhesive does, try using some Isopropyl alcohol to clean the back of the phone, and it should stick better. Also, don't apply heat to the screen, just in case that wasn't clear.

Used a corn bag (usually used for sore muscles) and incased the phone. It was hot to the touch, but it did the trick. Also needed a knife to have a small enough edge to start prying the back off and get the adhesive to finally pop.

Don't Forget Step 0! Turn the phone Off and remove the SIM card tray. just to be safe, I'd recommend making a full backup of your phone onto a micro SD card in case the worst should happen. also, make sure anyone who needs to contact you knows you aren't currently available at your phone number.

We went for a hairdryer. Put it on hot, low blow and put the head right up to the corner. Took maybe 5 minutes per corner!

Removing the back wasn't too difficult on my phone: several rounds of heating with the iOpener, applying gentle pressure with the suction cup, and eventually a corner lifted up without much force and I could easily slide a pick in. From there it was very straightforward and I had no trouble sliding the picks around and removing the back. The battery removal was much harder in comparison (especially as the iOpener burst when reheating in the microwave for the battery, despite following the time instructions).
