Mi presento sono Alessandro e da anni ormai ricevo aiuto dalle vostre guide di riparazione. Per questo, grazie a tutti coloro che si impegnano a farle così dettagliate!

Arrivo al dunque: un mio amico si è presentato sull'uscio della mia porta con il suo amato iPhone 12 Pro Max (parecchio malandato, allego foto) e un ricambio (acquistato non so bene dove) chiedendo il mio aiuto.

[a sx il vetro di ricambio, a dx il telefono rotto]

Sinceramente non saprei da dove partire (qualche idea si, ma vorrei evitare di peggiorare la situazione)

A mio parere inizierei applicando nastro sul retro, preparerei l'iOpener e proverei a rimuovere quel che resta del vetro posteriore.

Per riattacare il nuovo vetro invece ho idea che manchi l'adesivo, che dal precedente sicuramente non recupereremo.

Chiedo se qualcuno ha già avuto questa problematica e sa inviarmi sulla giusta strada

Grazie a tutti :)

Al montaggio del cellulare risulta non funzionante lo scanner Lidar, ho provato a prenderlo da un altro dispositivo ma il problema persiste.

Invertendo gli scanner non funzionano nessuno dei 2, questi sono correlati alla scheda madre come display o batteria? O la sostituzione del

Componente non dovrebbe causare alcun problema?

I recently replaced the battery in my iPhone 12 Pro Max with an iFixit battery kit specifically designed for the iPhone 12 Pro Max. During the installation, I carefully followed all of iFixit’s recommendations, including the battery calibration procedure.

For the first few days, I noticed a significant improvement in battery life and overall performance. However, recently I encountered a concerning issue. While charging the phone, it became so hot that the charging process was automatically stopped due to the high temperature.

Since then, the battery no longer seems to last as long as it did immediately after the replacement. In addition, the phone gets noticeably hotter during both charging and normal use compared to the original Apple battery that was previously installed.

Has anyone experienced something similar with an iFixit battery? Could this indicate a defective battery, an installation issue, or perhaps another hardware problem? What troubleshooting steps would you recommend?

Thank you for any advice.

I noticed the proximity sensor cable had a cut, so I tried taping it as a temporary fix and reconnected everything.

Now, when I turn the phone on, it vibrates, makes sounds, and the backlight turns on, but nothing shows on the screen. It stays completely black with no image at all.

I’ve tried both the original screen and the new replacement screen, and the result is the same — backlight works, but no display.

What could be the issue?

I tried updating to iOS 26 and also updated my Apple Watch, but the phone became even more unstable with constant restarts. I had to keep power cycling it, so I rolled back to iOS 18.5, which stabilized things. Even then, I had to restart the phone dozens of times just to get WiFi options to appear when signing into iCloud. However, now my Apple Watch won't pair anymore (and I've completely lost NFC functionality - the phone just doesn't detect it at all, though I can live without this since I can always use my Apple Watch for payments).

After two weeks, I attempted installing iOS 26 beta 6 from iOS 18.5 (I had previously tried iOS 26 beta 2), hoping the issues might be resolved, but the same problems returned - shutdowns followed by complete connectivity loss. I've since downgraded to iOS 18.6 since 18.5 is no longer supported.

My theory is that overheating triggers the shutdowns, which somehow disables the network radios. Sometimes while listening to music through Bluetooth, after a few minutes the phone would shut down, but after 2-5 attempts of turning the phone back on, the connections would return - as if the phone needed to be hot for the connections to work properly. I suspect the WiFi antenna might be causing the resets, so I've ordered a replacement and want to attempt the repair myself. However, I'm struggling with the disassembly.

From YouTube tutorials, the component I need to access should come off with the screen assembly, but mine doesn't seem to work that way. There's also this additional metal frame surrounding the phone that's blocking access to screws (like a metal cover over the camera module). Is this standard on all iPhones, or some kind of water damage protection?

I'd really appreciate guidance on which screws to remove or a link to a proper tutorial. The last time the phone restarted on iOS 26 beta 6, it was just sitting on my desk, and when I saw the Apple logo appear and realized it had restarted itself, I knew I was in for a rough few days ahead. I simply can't afford to have random restarts where I lose access to cellular data and WiFi, forcing me to restart the phone ten or even hundreds of times. I'm trying to repair it myself because I think the repair costs would gradually exceed the phone's actual value. If I can't manage to fix it, unfortunately I'll have to buy a new one.

Thanks in advance for any tips and advice that will help me repair the phone! Have a great weekend! (Sorry for the photo quality - taken with an iPhone 6s Plus while trying to repair his older brother.)

Since i swapped the chassis and misplaced this piece the screen is mot working anymore. So i suspect the issue is this little piece which might ground something or avoid something to ground.

Any one could bring a bit of light?

Thank you and Happy New Year!
