Solved: iPhone 6 won’t boot and report iTunes error 53

The iPhone 6 won't boot , after use iTunes to flash it, it reports unknown error 53, what's going on？ Trouble details is that the iPhone 6 fingerprint function is unavailable, then we repair it, after that, the iPhone reports error 53 and won't turn on. We can solve it ！



Disassemble the iPhone 6 device and use DC power supply to test, when power on the iPhone 6  (click the power button moment), the current value reaches 200-250MA.

The current value of normal iPhone should be around 50-60 Ma.

It is obvious that there is a leakage of electricity. Leakage and fingerprint failure, it can be preliminarly judged that the iPhone 6 fingerprint part has electric leakage phenomenon, resulting in fingerprint failure.

And for repair the error 53. First, measure the 2 power supply of fingerprint. 3.0V voltage is measured low. The value is very close to short circuit!

So it can be judged the problem is 3.0V short-circuit, which caused by low power 3.0V on fingerprint so that it would get unresponsive, for error 53, now we know the circuit is short, of course the rosin is required ( Apply rosin to smoke the relevant parts into white, then add the voltage on the short-circuit part, voltage was gradually increased (do not exceed the nominal value of 3.0V) until the right part gets heated and turns into different color because large current, then replace a new one to solve the problem)

After the components get into white, add the voltage in the right hand side of the second pin(the negative pole of Fluke 15B+ Digital Multimeterconnects ground first, use positive pole to clip a sharp meter pen, and touch the short-circuit part by the pen, adust the voltage from 0.8V gradually increased until the short part gets heating and changes color), you can observe more carefully by phone repair  Trinocular Stereo microscope or magnifying glass.


Open the WUXINJI dongle to check the location map is C2132, then check the capacitor C2134 principle diagram, we can see the part changes color is the bypass capacitor of capacitance PP3V0_MESA fingerprint power supply, the capacitor short-circuit is resulting in abnormal PP3V0_MESA, so this caused fingerprint and boot failure, error 53, after removing the several capacitors, the troubles are finally solved!

After installation, measure the iPhone again, now the iPhone flash smoothly, and then get into IOS successfully.

Essential tools for a phone repair technician Everyday Use

Must-Have tools for a phone repair technician include precision screwdrivers, spudgers, tweezers, suction cups, and heat guns or hair dryers. Additionally, anti-static mats and wrist straps are crucial for protecting sensitive electronics. Other helpful tools include a multimeter, soldering iron, magnifying lamp or microscope, and various cleaning supplies.  Whether you're a DIY enthusiast or a professional technician, having the right tools is crucial for successful phone repair. Here's a breakdown of common phone repair tools, categorized for clarity: I. Essential Opening and Disassembly Tools: Precision Screwdrivers : These are the most fundamental tools. Phones use tiny screws of various types (Phillips, Pentalobe, Torx, Flathead), so a comprehensive set with magnetic tips is highly recommended to avoid stripping screws and losing tiny parts. Spudgers ( Pry Tools ): Made of plastic or nylon, these non-conductive tools are invaluable for safely prying open phone casings...
