I have a problem with this iPhone that randomly turns off while using it. Not bootlooping, just shuts down and has to be turned on again. Checked analysis and this panic log appears everytime it shuts down:“panicString” : “panic(cpu 1 caller 0xfffffff029c14e80): "i2c3::_checkBusStatus SCL is stuck low; last write status 00010108 int shadow 00010100 xfer 00000000 fifo 00000000 for device roswell" What does “device roswell” means?
Hello Jimmy, Is your phone restarting at regular intervals? According to what you wrote, i2c data bus row 3 resistance is too high. Sometimes it is related to an outdated display driver, more often to a short circuit in the power supply of the pp1v8_s2 line. Consider that the i2c3 line extends from the CPU to powering the cameras to the touch screen function (Roswell is the screen touch driver and where the screen serial number is stored). Recently, often someone in this area is poking around to turn off the message about the non-original screen (which is just charlatanism, according to the instructions straight from the Chinese). I would write more about panic.log messages but recently the administrators of this forum have declared a crusade for me and are erasing data for such information, for reasons that are unclear to me. That’s why I can’t post a link to my article here. Find it on my blog (how to understand panic.full log in iPhone and iPad). Details in my description.
