Trouble Phenomenon

iPhone 5S displays blue screen and reboots automatically. It cannot be rooted.

IPhone 5s reboots after displaying a blue screen because PCB under screw holes disconnects of because of U6 chip. The material object location of U6 chip is shown in picture 2-9. Use multimeter to measure the diode data of the chip signal and it is normal, so is the voltage. Therefore, the chip is damaged. Replace a new U16X chip and trouble is removed.

If you need re-programming the U6 chip, MJ ACT PLUS tool  is useful tool, MJ ACT PLUS baseband eeprom ic test fixture, stay-in-place Baseband eeprom IC on iphone motherboard, Support 4S, 5. 5C/5S, 6, 6P, 6S, 6SP all iphone model CHIP, Erasing / Reading / Re-writing / opening CHIP (Baseband eeprom IC)data, check CHIP good / bad status, erase & format chip.

Picture 19-3-1 Look at the location map on WUXINJI dongle , it is surrounded by a ground wire, in fact, there are 6 useful points dropped. The ground wire does not need to be filled, the 6 useful points are added by professional phone welding tools. These are the signal wires of the NFC chip, so the iPhone X would report error 56.

After checking, we found signs of corrosion in the fingerprint socket, and then detect MESA_TO_BOOST_EN_CONN. Use Fluke 15B+ Digital Multimeter  to measure the diode data of PP16V5_MESA_CONN fingerprint boost boot signal and 16.5V, the data is normal. Observe the iPhone PCB board carefully under the VGA Camera 7-45X Trinocular Stereo Microscope  , we found something else. The bottom pin was severely corroded after the corrosion was removed from the fingerprint boost U4040. A2 pin PP_VCC_MAIN is disconn...
