If you’ve ever encountered iTunes Error 4013 or seen your iPad or iPhone stuck in an Apple logo boot loop, you know how frustrating it can be. For many users, these issues signal the end of their device—or worse, the loss of irreplaceable data. But after years of experience with micro-soldering and CPU rework, we’ve cracked the code on these issues, particularly for iPad mini and iPhone 6 devices. Here’s what we’ve learned and how we can help.
The Mystery Behind iTunes Error 4013
Our journey began in 2021 when we saw an iPad 6 stuck in a boot loop, endlessly flashing the Apple logo and failing iTunes updates with the infamous Error 4013. This error code is Apple’s generic way of saying, “Something isn’t right.”
The device was in pristine condition—no water damage, no scratches—but the CPU appeared to be completely unresponsive. Even with a known good battery and housing, the iPad’s logic board refused to boot. It was, as we call it, “brain-dead.”
Connecting the Dots: A Breakthrough
Over time, similar cases came in. One iPad mini, brought to us by a talented artist, contained priceless creations on the Procreate app. The stakes were high. We noticed that the charge port and a USB permission chip on the logic board had been damaged. After repairing those, the CPU was still unresponsive.
In a last-ditch effort, we performed a CPU and NAND transfer to a known-good receiver board. To our surprise, the iPad booted up! All the artist’s data was recovered, and we finally had a lead on solving this mystery.
What Causes iTunes Error 4013?
After repeated cases, we’ve identified the culprit: aftermarket chargers. They don’t just damage the charging port or USB circuitry; in some instances, they affect the CPU itself. This is especially true for devices with the A10 CPU, like the iPad 7 and iPhone 7.
How We Fix It
Through trial, error, and expertise, we’ve refined a solution that doesn’t require transferring the CPU to a receiver board. Instead, we:
- Remove the CPU carefully.
- Clean the hard electrical underfill glue from both the CPU and logic board.
- Resolder new conductive balls to the CPU.
- Reattach the CPU in its original position.
This process, called CPU rebelling, brings these devices back to life and ensures that all data is intact.
Can Other Devices Be Fixed?
While this issue seems to be most common in the iPad 6 and iPhone X and XR, we’ve started exploring whether the same method could work for other devices with similar symptoms. So far, the results are promising.
