线刷包修改oppor831t分区MTK有Androidscatter文件通用用SPflashtool工具刷入

调整data.cachesystem分区大小

打开线刷OPPOR831T刷机包，会看到一些文件

这里说下每个刷机文件对应的文件名

PRELOADER→preloader.bin

MBR→MBR

EBR1→EBR1

UBOOT→lk.bin

BOOTIMG→boot.img

RECOVERY→recovery.img

SEC_RO→secro.img

LOGO→logo.bin

EBR2→EBR2

ANDROID→system.img

这就是线刷工具能识别到的文件名，一定要改成对应的名称

要打开

MT6572_Android_scatter_emmcTXT

这个时候就要用到Notepad++了，打开桌面上的新建文件夹单机scatter_emmc.txt文件，再用Notepad++打开

于是看到一下内容

以上是原文件的内容

打开电脑自带的计算器

我用的是win7所以点击开始菜单→所有程序→附件→计算器

XP的好像是开始→程序→附件→计算器

打开计算器点击左上角的查看→选择程序员再点击十六进制

XP的好像是选择科学型然后再选择十六进制

计算回读文件的长度必须要用十六进制计算

长度的计算就是结束地址减开始地址，不必一个一个的输入，只需复制粘贴即可，点击计算器菜单栏的编辑选项即可复制粘贴。

这里特别说明，开始地址和结束地址前面那个0x是不用输入的，也无法输入到计算器，所以只需复制0x后面的数

既然MBR结束地址是0xc80000那么就复制c80000再粘贴到计算器，然后再点击计算器上的—按钮之后再把开始地址c00000复制粘贴到计算器，之后再点=按钮然后就算出长度了。

每个英文后面的0x就是开始地址，而下一个英文后面的Ox就是结束地址

结束地址减开始地址就等于长度

这里可以看出preloader的开始地址是0x0结束地址是0xc00000

MBR的开始地址是0xc00000结束地址是0xc80000

MBR的开始地址就是preloader的结束地址

也就是说，下一个文件的开始地址就是上一个文件的结束地址

那么就把c80000-c00000=80000

80000就是长度

计算出长度转换为十进制大小。

计算方法：

在计算器“查看”菜单下，将计算器切换到“程序员”，输入对应分区的16进制数值，点“10进制”转化为相应的10进制数值；计算器切换成“科学型”，输入刚转换好的10进制数值（单位是Byte），除两次1024，即可得到分区大小（单位是MB）。

还有完整的线刷包只需

回读PRELOADER，
