Stop Guessing at iPhone Panic Logs
Panic logs can provide valuable information about why an iPhone is restarting, but identifying the actual cause is not always straightforward.
A panic log may point toward a charging-port assembly, proximity sensor, power circuit, missing sensor, damaged flex cable, or a board-level issue. The difficult part is knowing which component is responsible on each particular iPhone model.
That is why I created the VCC Panic Log Cheat Sheet.
Personally Tested and Verified Solutions
This is not a generic list copied from forums or collected from unverified posts.
The cheat sheet is based on panic logs and solutions I have personally tested and verified while repairing iPhones at VCC Board Repairs. It covers virtually every iPhone model and documents the parts, sensors, flex cables, and circuits commonly associated with specific panic strings and numerical values.
The goal is simple: help repair technicians diagnose restart issues faster and avoid wasting time or money replacing the wrong parts.
What’s Included?
The Panic Log Cheat Sheet helps technicians:
Identify common iPhone panic strings and numerical sensor codes
Match panic logs with the components most likely causing them
Compare model-specific differences
Determine which part or circuit should be tested first
Reduce unnecessary parts swapping
Diagnose difficult restart issues more efficiently
It is designed to be a practical reference you can pull up while actively diagnosing a device.
Constantly Updated as New Panic Logs Are Discovered
Apple continues releasing new iPhone models, and the meaning of a panic log can vary between generations.
As I get new models on my bench, I test them, document which parts cause specific panic logs, and add those findings to the cheat sheet. I also update the document whenever new panic strings, sensor values, or confirmed solutions are discovered.
Instead of purchasing a static document that eventually becomes outdated, active supporters receive access to a resource that continues to grow.

If you have a Seek Thermal Cam, you're missing out if you don't have a VCC Seek Stand: https://www.vccboardrepairs.com/buy-seek-stand
Injured Gadgets just got these back in stock, so get them while you can!
It can take us a while to build these out sometimes, so they're sometimes out of stock for a while, but we're working towards always having inventory ready to build more as they sell out.
This stand makes using a thermal cam so easy. So much better than any other thermal solution on the market.
It allows you to get real close up (using my Macro Lens), and easily find where the short is coming from.
Plus it's hard free, so you can have your hands free to try to boot the device from DCPS, while having an image that is in focus & not moving around.
You can even record a video through the app, while you inject voltage into the short, so you can go back & see exactly which component was it that was heating up.
Save yourself lots of time by getting a Seek Cam, Stand & Macro Lens! ...
Anyone who is doing game console repairs, knows how many screws you need to remove to access the motherboard.
Especially the PS5, with the 5,000 screws or so.
If you don't already have an electric screwdriver, GET ONE ASAP.
🌟 Cordless Screwdriver with T9 Bit: https://amzn.to/3E5duCj
🌟Extended T9 Bit: https://amzn.to/3c4YJac
It's rechargeable through micro USB and allows you to easily swap the tips out. You can also fold it to be straight or L shape.

In case you haven't heard, I will be moving from Las Vegas, NV to Star, ID.
In my Las Vegas office, I had fully custom built workbenches for myself & my employee(s). But now it's time to go & tear everything down.
I'm really sad since these benches felt like the perfect layout! Or maybe I just got used to them.
I've attached some pics of what it looked like before & now that's all gone.
I do have some good news tho.... I recorded a detailed video of my office for youtube! I'll be posting that video soon!
Like this post if you want to see that video!
Hey guys! I'm so glad to finally get here. Thank you Jesse for the encouragement. Took me a minute but I'm here. I'm so eager to learn and grow. I have some experience with soldering etc, I can treat with obvious issues but there's something about diagnosing issues (especially with iPhones) that I have trouble with. I'm hoping this community can help with that.
Currently I have two iPhone 13 devices that need repair. One is stuck in recovery mode. A flash was attempted but there was an error during the process (Error 4013).
The other 13 does not boot or charge. It pulls 0.02A on the ammeter and I can feel both the back getting really hot. I tried this with two batteries. I also noticed that the wireless charging IC also gets very hot (338S00817) even when using a wired charger.
Remember I'm a noob so please....be gentle. Any help greatly appreciated. Thanks in advance!
