iPhone 12 Pro Max Chip-Level Service
Published by TurboFix, Hyderabad · Last updated · 1 sources
Quick answer
Chip-level service finds and replaces the failed component on the iPhone 12 Pro Max's original A14 Bionic board. If it succeeds, your data, Face ID and IMEI stay as they were — which a motherboard replacement can't offer.
When an iPhone 12 Pro Max won't power on, won't charge even with a new port, loses mobile signal or stops working after liquid exposure, the fault is often a single component on the logic board. Chip-level service finds and replaces that component, keeping your original board.
That matters because the iPhone 12 Pro Max's storage and Face ID are tied to its original board. If the board can be revived, your data and Face ID come back with it.

What makes the iPhone 12 Pro Max different for this service?
- Chip: A14 Bionic.
- Charging circuitry: Lightning models use dedicated charging and port-control chips; failures there can stop charging even with a new port.
How does chip-level service differ across the iPhone 12 series (2020)?
As the first 5G iPhones, the iPhone 12 series added more radio hardware to the logic board. No-service or 5G-only faults on a iPhone 12 Pro Max need board-level diagnosis rather than a new SIM tray or software reset once the basics are ruled out.
What should I check on my iPhone 12 Pro Max before booking?
- The iPhone 12 Pro Max went on sale in November 2020, so unless it was bought much later or has extended cover, it's likely outside Apple's one-year limited warranty. You can confirm at checkcoverage.apple.com.
What do we test on your iPhone 12 Pro Max before handing it back?
These checks are chosen for the iPhone 12 Pro Max's hardware, so features this model has are confirmed working after chip-level service:
- Face ID set-up and unlock
- Lightning charging with a reference cable
- MagSafe alignment and wireless charging
- Ring/Silent switch
- Calls on earpiece and speakerphone, and Voice Memo recording
- Mobile data including 5G where available, Wi-Fi and Bluetooth

IPhone 12 Pro Max chip-level service: frequently asked questions
What is chip-level service?
It's component-level work on the iPhone 12 Pro Max's logic board: finding the failed part — a power chip, a connector, a filter, a short circuit — and replacing just that component under a microscope, rather than replacing the whole board.
Can you recover data from a dead iPhone 12 Pro Max?
Only by getting the original board working again, because the storage is encrypted to that board. If the fault is in a repairable component, data is often reachable once the phone boots. We can't promise recovery before diagnosis, and some faults (for example a failed processor or storage chip) make it impossible.
Is chip-level work on a iPhone 12 Pro Max done at my doorstep?
Board-level work needs a microscope and a soldering bench, so it may not be possible at your doorstep. We'll tell you when you book; pickup and delivery are available, or you can bring the phone to our Nampally studio.
My iPhone 12 Pro Max stopped working after water damage. Is chip-level service the right option?
Often, yes. Apple rates the iPhone 12 Pro Max IP68 (up to 6 metres for 30 minutes) when new, but that resistance wears over time and doesn't cover every kind of liquid. Liquid that gets in causes corrosion and shorts on specific parts of the board, and cleaning and replacing those components can bring a phone back. The sooner it's looked at, the better — don't charge a phone that has been in water.
How long does chip-level work on a iPhone 12 Pro Max take, and how much does it cost?
Both depend on the fault, which we can only know after diagnosis. We give you a quote and an estimate after diagnosis, before starting the work.
My iPhone 12 Pro Max shows "No Service". Can chip-level work fix it?
Sometimes. After ruling out the SIM, carrier settings and a software restore, a no-service fault on the iPhone 12 Pro Max can come from the radio circuitry on the logic board, which needs board-level diagnosis. Some faults in the modem chip itself can't be repaired.
