Case Study Summary
- Client: Manessa (USA)
- Device: Apple iPhone 15
- Problem: Sudden shutdown, cracked CPU, iOS boot loop
- Solution: Chip level CPU repair and logic board recovery
- Outcome: All photos and videos successfully recovered
This iPhone 15 data recovery case study documents a complex recovery involving a cracked CPU and persistent iOS boot loop. The device suddenly powered off and could not be revived by standard repair methods. After an unsuccessful attempt by a US based provider, the phone was sent to Australia for specialist assessment and recovery.
The problem: sudden shutdown and cracked CPU
The iPhone 15 powered off unexpectedly while still holding charge and would not turn back on. There was no visible external damage. Internal inspection confirmed a cracked CPU, where any mistake during repair would permanently destroy the data.
The iPhone 15 data recovery process
This iPhone 15 data recovery case study required manual silicon layer removal using chip level techniques. The data recovery engineer carefully removed damaged layers over multiple attempts until intact circuitry was exposed. This process required extreme precision and could not be repeated indefinitely.
Once the device was able to power on, a secondary issue appeared. The phone entered an iOS boot loop caused by memory read errors. Further work was required to stabilise the logic board and allow controlled access to the encrypted storage.
iOS boot loop and memory corruption
An iOS boot loop occurs when the system cannot complete startup due to corrupted system files or hardware level read errors. In this case, memory related corruption prevented normal operation. Advanced diagnostics and logic board repair were required before data extraction could proceed.
For background information on iOS boot loops, see Apple’s official support documentation:
Apple iPhone startup issues.
Recovery results
All photos and videos were recovered successfully. This outcome demonstrates that even severe CPU level damage does not always mean permanent data loss when specialist techniques are used.
Important limitations
Not all cracked CPU cases are recoverable. Success depends on the exact location and severity of the damage.
Why People Choose Payam Data Recovery
When an iPhone will not start, its data is locked to its own chips, so those chips have to be working again before anything can be copied. That is the work we do every day.
- We are a specialist data recovery lab, not a phone repair shop. We have been recovering data since 1998, from over 300,000 devices.
- We are listed on Apple’s data recovery provider page, one of three recommended data recovery providers.
- 500 mobile phone repair shops and over 2,000 IT companies and computer shops across Australia send us their customers’ complex cases every year.
- Board level repair under the microscope by our own data recovery engineers, here in Australia and never outsourced overseas.
- Your data stays private. Our data recovery engineers open only a few random, non-sensitive files to check the recovery worked, and we can sign an NDA on request.

Frequently Asked Questions
My iPhone switched off suddenly and will not turn on, but there is no visible damage. What causes that?
Damage inside the phone does not always show on the outside. This iPhone 15 powered off while it still held charge and had no external marks at all. Internal inspection found a cracked CPU.
Can data be recovered from a cracked CPU?
Sometimes, but it is among the most demanding work we do. It required manual removal of the damaged silicon layers over several attempts until intact circuitry was exposed, and the process cannot be repeated indefinitely. In this case all the photos and videos were recovered.
Someone has already attempted a repair. Is it too late?
Not necessarily. This phone had already been through an unsuccessful recovery attempt before it reached our lab, and the data was still recovered. What changes is the work involved.
What is an iOS boot loop?
It is when the phone cannot complete startup, either from corrupted system files or hardware level read errors. Here the phone entered a boot loop from memory related corruption even after it could power on, and further work was needed to stabilise the board before the encrypted storage could be read.
Do you accept devices from overseas?
Yes. International customers are always welcome. This iPhone was sent to us from the United States after an attempt there was unsuccessful. The easiest way for an international customer to reach us is by email at help@payam.com.au, which works in every time zone.
