上文跟大家讲了创维8H73机芯（海思方案）的刷机方法，还有一种故障现象是大家比较关注的，灰屏！
此机芯的屏参是保存在外挂的24C32（U0M1）中，所以刷写主程序是不会改变屏参的，这也是让很多维修员烦恼的过程，而灰屏故障又分为软件故障（屏参）和硬件故障，如何快速的区分是非常重要的！今天就跟大家聊聊此机芯安卓控制台下屏参调整方法。
大家现在知道屏参在U0M1中，有小伙伴问，直接更换24C32行不行？只要你有一模一样相同屏参数的主板，直接拷贝24C32内数据是可以的，不过这种情况不好遇到，咱们还是来点简单方法吧！
在介绍方法之前，先跟大家分享一下此机芯最新支持屏参表，此表是iFix君在最新固件内提取的，供大家参考。

一、查看当前屏参
从上面的屏参表可以看出，目前最新固件支持172种屏参，灰屏故障第一步，首先是要查看当前屏参是否跟自己的屏型号一致，不过在开始之前，先连接好编程器的串口，并打开“SecureCRT超级终端”。
开机完全启动后，按回车进入安卓控制台，控制台下输入i2c_read0 0xa0 0 2 3后回车，如下图：
可以看到回车后显示：0xA8，A8就是当前屏参选择项，这个A8到底是什么意思呢？A8其实是16进制显示，我们把它换算成十进制就知道了，那么怎么换算呢？告诉大家一个简单方法，用电脑附件自带的计算器就非常方便。
打开电脑计算器，点查看，选择程序员：
选左边的十六进制，然后点A8；
然后点左边十进制，上面就显示十进制的数字“168”，简单吧！
也就是说当前屏参为index168，查上表对应屏参 index168----M6_7626_T6500Q_Y140_RDL650WY_QD0_006
二、更改屏参
更改屏参前，查看172项屏参表，找到自己需要的屏参，例如我们要改屏参为 index170----M6_7618-T6500B-Y010_SDL650WY_LD0_000，那么输入如下命令：
hidebug <回车> factory <回车> spi 170 <回车>
重启电源，进入工厂模式，查看一下当前屏参，在本机信息界面按方向键上上下下左右左右可进入工厂模式，如下图:
从上图，可以看出，屏参修改成功，正常显示，屏参修改知识你掌握了吗？下节我们再一起学习新的知识点吧！
