00:00:00,366 --> 00:00:04,500

The maintenance of iPhone startup constant current and current jump faults

2

00:00:04,933 --> 00:00:10,366

In this video, we mainly explain step 2 of the maintenance process, flashing error

3

00:00:10,766 --> 00:00:13,066

Operation method of flashing error

4

00:00:13,533 --> 00:00:18,633

When repairing constant current or current jump faults, we need to flash the machine

5

00:00:19,133 --> 00:00:21,733

First download the flashing software

6

00:00:22,900 --> 00:00:26,000

There are 3 flashing softwares commonly used in maintenance,

7

00:00:26,233 --> 00:00:30,566

iTunes, Aisi Assistant and Hourglass Assistant

8

00:00:32,500 --> 00:00:37,733

We can use these 3 softwares to flash the machine, so as to judge the fault

9

00:00:45,900 --> 00:00:50,666

When downloading iTunes, we need to download from the official website

10

00:00:51,300 --> 00:00:55,166

If the computer is Windows system, we choose Windows system

11

00:00:56,666 --> 00:01:01,200

Choose 64-bits or 32-bits according to the version of the system

12

00:01:01,533 --> 00:01:03,866

Download it and install it directly

13

00:01:04,166 --> 00:01:08,733

The download method of Aisi Assistant and Hourglass Assistant is the same

14

00:01:13,266 --> 00:01:17,200

Next, we need to download the system firmware for flashing,

15

00:01:18,400 --> 00:01:21,433

usually we download it in Aisi Assistant

16

00:01:23,000 --> 00:01:24,933

OK, let me demonstrate

17

00:01:25,166 --> 00:01:27,400

First open Aisi Assistant,

18

00:01:27,800 --> 00:01:29,333

click Smart Flash,

19

00:01:31,666 --> 00:01:33,433

click Download Firmware

20

00:01:35,700 --> 00:01:37,300

Select iPhone here,

21

00:01:43,966 --> 00:01:46,400

and then select the corresponding model

22

00:01:49,833 --> 00:01:52,266

Then select the Apple system version

23

00:01:52,700 --> 00:01:56,700

Can not choose the old version of the system, only the latest

24

00:01:58,066 --> 00:02:02,433

If there is a green mark in the version, it means that the system is available

25

00:02:04,833 --> 00:02:07,700

Those without the green mark belong to the old system,

26

00:02:07,933 --> 00:02:11,100

even if you download it, you can't use it

27

00:02:11,733 --> 00:02:14,933

After selecting the system, we click download

28

00:02:19,200 --> 00:02:21,366

If the iPhone can connect to the computer,

29

00:02:21,566 --> 00:02:23,400

we don't have to operate like this

30

00:02:23,633 --> 00:02:25,833

Click on the one-key flashing machine,

31

00:02:26,000 --> 00:02:30,866

it will automatically help you choose the installation package that can flash the machine,

32

00:02:31,100 --> 00:02:32,500

we can click download

33

00:02:33,166 --> 00:02:35,000

So, that's it for this lesson
