iTunes reports error codes when it is upgrading/ in the recovery mode
Verifying CPU- verifying memory- verifying hard disk- progress bar starts loading ( write hard disk)- when it writes to 50%, it indicates that the hard disk is finished writing
Baseband verification- write baseband- when the progress bar moves to 80%, it prompts that the baseband is finished writing- testing NFC- write NFC
1. If the progress bar reports error before 50% (included the progress bar does not appear or not loading), the fault appears at CPU, hard disk, U0301 or compass (if the progress bar does not display, it’s the fault about hard disk and CPU). If the co-processor cannot load or the U0301 loads a little bit, we need to reassemble or replace the hard disk, besides, we need to replace the compass and co-processor and reinstall the CPU.
2. When the progress bar moves to 50% and the error pops up, it indicates that the problem is on the baseband CPU and baseband power. What we need to do is to change the baseband power and reinstall CPU.
3. The error appears when the progress bar loads 80% or 99%, it means that the baseband has been written and the malfunction is on NFC, baseband power and baseband CPU.
iPhone error codes when resetting system
Error -1: Baseband CPU fault or the chip or the output of baseband power supply is abnormal
Error 1: Baseband CPU fault or the baseband power is not working.
Error 2: Baseband, not excluding power supply
Error 3: Currently, it has two kinds of progresses reporting error
1. If the error appears when resetting the system during 2/3, it has a great possibility that the baseband is physically damaged.
2. If the error occurs when the progress bar goes to 99% in the recovery mode, it is certain that it is the chip fault. Let’s try to fix it first, if it does not work, we can replace the clock near the baseband power or change/ reinstall the IF.
Error 6: Hard disk, when the progress bar runs to 2/3, it ’s the chip fault
Error 9: Hard disk. We should check the power supply of the hard disk, and the hard disk may be pseudo soldered.
Error 10: server authentication problem. Wi-Fi is broken or the CPU is pseudo soldered. Besides, replacing CPU of iPhone 6 will also appear this error.
Error 11: Check whether the firmware is complete or not.
Error 12: Firmware shutdown verification.
Error 14: Hard disk, check the resistance value between the hard disk and CPU. Blue screen fault is mostly caused by the disconnected communication bus between hard disk and CPU.
Error 14: Blue screen is mostly because the board layers have disconnection.
Error 15: It is generally the hard disk fault and we cannot exclude the hard disk power supply.
Error 16: Baseband CPU to chips, mostly are chips.
Error 20: Reset the system in DFU mode.
Error 21: Upper cover of CPU, battery.
Error 23: 8824. Short the baseband of the phone version that is over 7.11 will cause error 21 and error 23. Please remove the FL8 and VCC power supply before entering the recovery mode. The motherboard has big current will report error 21, at the same time, the short- circuit of baseband will also cause error 21 and error 23.
Error 26: Baseband CPU to chips.
Error 27: Chips data is not matched, please use the chips reader to restore chips.
Error 28: CPU or hard disk
Error 29: Please check the detected pins of battery, or maybe the battery is defective or it has network problems.
Error 31: baseband
Error 40: Hard disk problem, cannot exclude the power supply of hard disk
Error 47: Chips or communication CPU
Error 48: Baseband CPU or chips are damaged and the chips can probably be fixed.
Error 50: Baseband CPU fault
Error 53: Touch ID fingerprint, server authentication
Error 56: Mostly are NFC problems. Baseband CPU to chips. In iPhone 6, it is mostly because of rear camera or camera power supplies.
Error 91: hard disk
Error 1003: Baseband or hard disk
Error 1005: hard disk
Error 1013: Server authentication problem
Error 1015: It’s the degraded firmware that causes malfunction, we need to fix PC first and then reset iPhone’ s system
Error 1600: CPU
Error 1601: CPU
Error 1602: USB power supply or system fault
Error 1611: hard disk pseudo soldered
Error 1669: Chips, data loss or wrong data; if the charging socket of 6s burnt, it will report error 1669
Error 2002: You should detect whether it connects the Apple server, it is related with the proxy server you use
Error 2003: Change USB or PC
Error 2009: Change PC and wait for a while, hard disk, power supply
Error 3004: battery, data cable, or the USB interface of PC is not stable
Error 3014: Check whether the PC is connected normally. When degrading, you should check whether the backup of server SHSH is normal.
Error 3049: CPU
Error 3194: Firmware is incompatible, 1. The verification is closed 2.Remove the components to other motherboard 3. The outer area is not communicated 4. Charging socket 5. Data wire 6. The firewall of PC is on
Error 4005: Hard disk fault, does not exclude the power supply of hard disk or change a PC.
Error 4013: Blurred screen, I2C is shorted or pseudo soldered. The chips on the connected circuit are the bottom layer of CPU, hard disk, U2, Wi-Fi, etc., maybe there is something to do with baseband
Error 4014: CPU, maybe the hard disk circuit
Error 4015: upper layer of CPU
Error 0xe800006B: check whether the USB is normal and check whether the devices are connected properly.
Error DXEXXXX: iTunes is not installed in disk C.
Error -23: If iPad 6 reports error -23, it is because its battery is dead.
