iPhone 6 Plus Error 4014 Fixed Solutions
When your iPhone has error code 4014, you must consider to sent to repair store to fix. Put simply, the error is hardware related, if you don't really get to fix by yourself, it is the most troubling issue. Vip Fix Shop Team has a variety of solutions that worked. What we try here is to make sure you don't go about trying them randomly, because it will make easier to fix.
1. The 6 iPhone Plus can be normally used before, there were no any problems. But after changing the iPhone Nand for memory capacity expansion, it reports error 4014 when flashing it. As shown in picture 10-3-1.
2. When we flash the iPhone device, it displays error 4014 before progress bar showing up. It is restored and the serial number could be recognized, which appeares after Nand expansion. This is usually caused by the iPhone USB chips leading to CPU problem. We get to know it UMT motherboard after disassembly, then remove USB chip U1700 to measure resistance from solder
pad
to
CPU,
we
AP_TO_TRISTAR_ACC_UART6_TXD
find
that
shows
the
infinite value, as shown in picture 10-3-2 and 10-3-3. And AP_BI_12C0_SDA is also broken, as shown in picture 10-3-4 and 10-3-5.
3. The layer wire is disconnected, so we need to find out other connection point or digging for other holes,
AP_TO_TRISTAR_ACC_UART6_TXD
is
direct
connected without other external components, when digging
the
circuit
AP_TO_TRISTAR_ACC_UART6_TXD we find that there is a hole next to socket, dig it to solder jumper wire. As shown in picture 10-3-6, 10-3-7 and 10-3-8.
4. AP_BI_12C0_SDA has a test point outside of the iPhone circuit board, welding directly from the test point. As shown in picture 10-3-9 and 10-3-10.
5. Intall the iPhone USB chip back, we can flash the iPhone device normally now, repair ends here!
