What might be the likely solution to this
Iphone 14plus. With this issues below
SMC PANIC - ASSERTION
FAILED: target\/d28\target.cpp:266: 0, SMC BSC failure, spreadsheet ver (*10)
40\nS.sensor array 0 - 4 is 0x0, 0x600000,
Questa è una buona domanda?

gbenga, you've got the distinction of having encountered a unique and previously unknown error code. Well, one known and one unknown, actually.
The code you have is actually two codes, because there are two bits set. In hexadecimal, a 6 is made up of two different bits, a 4 and a 2. So your codes are individually 0x200000 and 0x400000. The 0x400000 is a code we know already; here's the information about it from the iPhone Kernel Panics wiki page.
Unfortunately, we haven't encountered the other code, 0x200000, previously so at this point we have no idea what it means or how to help you with it.
The only other time we've run into the charging flex issue was here.
hello I have iPhone 14 keeping restarting - iPhone 14 Pro - iFixit
In that case, apparently just the act of removing the rear cover and refitting it resolved the problem, but I'm afraid that's probably too much to hope for in your case, but worth a try.

Thanks for the suggestion, I’ve tried fixing the rear glass properly but still the same thing
@gbengabusari Can you tell us a little more about when this issue started? Did anything happen to the phone before it started, such as being dropped, getting wet, an update, etc.?
I have the exact same log and my iphone (15 pro) keeps restarting every 3 minutes. I haven't dropped it, I just bought it, brand new (yaay), and I cannot get an answer on what the problem really is. it is annoying because the phone can properly function for 1-2 weeks straight, and then, in a radom day it keeps restarting over and over for a whole day, then it goes back to "normal".
This issue is also affecting the camera (you cannot take wide pictures, camera defocuses the image, the front camera freezes, etc). I left the phone at a service and I will come back with more info on this.
Also, when apple support ran tests on my phone, multiple sensors failed: camera, accelerometer, temperature sensor, and some others, but I cannot remember all of them.
BTW, if I completely reset the phone, I don't have this issue anymore + all the tests pass, but after a while, it is not working properly anymore :D. idk if it is an actual hardware or software issue, but personally I'd go with hardware...and unfortunately, if this is the case, the problem is there from when this iphone was fabricated.

I just had this issue yesterday on an iphone 14 and I found this post and others with no answer.
SMC PANIC - ASSERTION
FAILED: target\/d28\target.cpp:266: 0, SMC BSC failure, spreadsheet ver (*10)
40\nS.sensor array 0 - 4 is 0x0, 0x600000
0x600000 is the gps antenna flex cable.
Its not posted anywhere else but im going to try to add it to repair and logic wiki when I have the chance.

AFTER a long search and i teste all solution after few hour i find the solution
the flex cable and sensor of proximity proximity sensor have some water and i replaced it and all thing working well
just replace it and all work fine bro ..

@lordofjesters jessepuglsey, I'm going to disagree with your conclusion and urge you to not make that change.
As a computer scientist, I have been working with binary data for 40 years now so I'm going to attempt to explain the error codes you are seeing. Note that I said codes, not code, because with these errors each binary digit represents a separate error, and you have two digits set, thus you are seeing two separate errors, not one.
Here's how it works. In the binary system you only have two values for a given number, 0 and 1, whereas in our normal decimal number system those go from 0 to 9. However, it's much too clumsy for us humans to work in binary since the numbers become huge, so instead we work in what's called hexadecimal, where the numbers go from 0 to 16. Now, we don't want to use two digits for everything above the number 9, so we start substituting letters instead, so 10 to 15 are represented as A to F. With me so far?
Now, let's count from 0 to 15 in decimal, binary, and hexadecimal
Decimal Binary Hexadecimal 0 0000 0 1 0001 1 2 0010 2 3 0011 3 4 0100 4 5 0101 5 6 0110 6 7 0111 7 8 1000 8 9 1001 9 10 1010 A 11 1011 B 12 1100 C 13 1101 D 14 1110 E 15 1111 F
Note that at Apple, hexadecimal numbers are indicated by prefixing the number with "0x", so 7 in hexadecimal would be 0x7, and 14 would be 0xE.
Now if you look at the binary data, what's happening with the Apple errors is that they are using each individual binary digit to represent a particular error. So for the iPhone 14, they're using bits like 0x200000 to indicate an error in the Front Sensor Assembly.
In your case, you're seeing the error code 0x600000. If we look at the binary digits column, under the value of 6 we see it represented in binary as 0110. Since each binary digit, or "bit" represents an error, what you're seeing is not one, but two errors. If we split them out into 0100 and 0010, we can see that we've actually got errors 4 and 2. We just saw that 0x200000 represents the Front Sensor Assembly, and according to the iPhone SMC Panic Assertion Failed wiki page, 0x400000 is a problem with the Wireless Charger Coil.
So I'm not sure where someone came up with the conclusion that 0x600000 means the gps antenna flex cable, but I can tell you for certain that's wrong; it's the two errors I just outlined.
Hopefully this clears up some confusion; if I get some free time I may see about adding this explanation to the Wiki page.
Side note to Alisha ( @flannelist ):
I see on the SMS Panic page there's an error code listed as 0x500000, and attributing that to the Battery. For the same reasons I just listed, this should be the two errors 0x100000 and 0x400000 (0x0001 + 0x0100 = 0x0101, or 1 + 4 = 5), aka a Charge Port Assembly error combined with that Wireless Charger Coil error.

Thanks for the input i did not know that apple broke down the one digit into multiple codes. Thats interesting as some of the error strings seem to be directly tied to the issues that people have listed as opposed to what you are saying.
I changed the gps antenna on a device yesterday with error code 0x600000 and it prevented the restart from happening...
I suppose these cases where you say the solution is wrong an example of actually doing the work versus theory?
@lordofjesters I see what you mean; as you correctly point out I am going by theory (well, that and 40 years in the computer business) whereas your experience with the repair actually fixing the problem is certainly hard to argue with.
Unfortunately, we're stuck with going by empirical evidence and theorizing on how things work since Apple refuses to share that sort of information.
The biggest argument I have is that if each numeric code is different; i.e., code 6 is not a combination of codes 4 and 2, then there is no way to tell you when it does encounter more than one error. For example, if you get code 4 and code 2, we could only report one of them if a code 6 is reserved for the gps antenna vs. the front sensor and wireless coil.
@dadibrokeit Funnily enough I also just had this conversation this morning Because I snagged the codes off the repair wiki when I wrote that and there is also a mistake there.
In my conversation from this morning, we decided it's likely that battery is 0x50000 rather 0x500000, which yes I believe is charge port flex + wireless charge coil. I can't always trust my own brain to put in the correct number of zeros. :D
40\nS.sensor array 0 - 4 is 0x0, 0x600000,

My apologies, I miscounted the number of zeroes on my previous response, so at this point the only information we have is still that the 0x400000 error is related to the wireless charging coil on the back glass.
Wireless charging cable or proximity flex

Hi everyone I got this broken iphone 14 fell pretty bad to this guy with the smc panic error 0x400000 restart every 3 min
But:
• Wireless Charging is working
• Proximity Sensor is working
• Flashlight isn't working
• Back camera isn't working
What I did:
• Replaced Display (it was broken)
• Replaced Battery (it was looking meh)
• Replaced Back Camera (I tought it not working might have caused something)
• Replaced Wireless Charging Coil and Flashlight (Single Flex Cable)
• Replaced Back Glass
What happens now:
• Still reboot every 3 minutes 0x400000
• Camera still not working
• Flashlight Still not working
Any suggestions?

Mounir, did you read the SMC Panic Assertion Failed wiki page?
iPhone SMC Panic Assertion Failed
The Likely Issue field for code 0x400000 on your phone has a footnote that explains what's going on.
***There is a sensor on the wireless charge coil cable that is paired/calibrated to the device. Replacing it with another back glass assembly, or wireless charge coil will result in the same issue, unless you use an Apple part (back glass) supplied by Apple's Self Service Repair program and run System Configuration.
It appears that the kernel panic continues to happen even after replacing the wireless charging coil unless you pair it to the phone, which can only be done with Apple's System Configuration utility.
If you've upgraded to iOS 18 you may have access to some reconfiguration, but I'm afraid I'm not conversant enough with it to tell you if it can help you with your problem. The only solution I can be sure of is mentioned in the footnote.

I actually haven't specifically seen mentions before of 0x60000, It's possible this a multiple parts problem, but I will have to do some research to know for sure.
