我是苹果手机维修工程师,有6年的工作经验
手机刷机报错3014,多数是硬件问题来的
苹果的系统为了方便后期的维修内置了很多报错的数字
不同的报错数字代表不同的含义。
3014,通常是主板硬盘故障或者cpu上盖最常见
这都是主板问题
很多人有个误区以为主板问题就要换个主板
其实主板上面有几十个主要芯片构成
如果芯片焊接的焊点脱落或者短路烧了
都是造成整个手机无法工作
有经验的维修师傅的工作就是找出这些问题所在
再更换故障的芯片,接通短路的线路
没有芯片维修能力的就让你换主板
换个芯片23百都有,换个主板23千呢
下图就是主板芯片修复的照片,以供参考

你好,
方法
1、当在使用 iTunes 为设备恢复或更新固件时提示未知错误 3014 时,请先关闭 iTunes 软件,然后重新打开 iTunes 软件再进行恢复或更新操作。
2、如果重新打开 iTunes 软件以后还是不行的话,请检查电脑网络当前的网络链接是否有故障,可以尝试打开此网站 官网。如果不能打开此网站,那说明电脑的网络连接访问有问题,请先解决网络故障。
3、如果上面的网站也可以访问,接下来请把 iOS 设备 和 电脑都重新启动一次。 iOS 设备请按住电源键开关不动,直到出现关机滑块,随后滑动滑块来关机;如果是处理恢复模式的 iOS 设备,请把电源键和Home键一起按住,iOS 设备关机以后再按电源键重新开机。等待 iOS 设备和电脑系统都重新启动以后,再打开 iTunes 来尝试重新恢复或更新固件系统。
4、如果上面的操作都已经试过还是不行的话,可以尝试把要恢复或更新的设备换一个环境,比如在朋友,公司的电脑上更新恢复。
