〖Android〗Nexus 7 flo (razor) 刷入Recovery/CM-11.0后卡在开机动画的解决方法

操作日志:

起因:Nexus 7 flo 华硕平板,刷了一个CWM Recovery之后变成了砖机;

尝试1:使用CWM Recovery清除数据,开机失败

尝试2:刷入CM 11 Snapshot的zip卡刷包,并使用Recovery清除数据,开机失败

尝试3:刷入CM 11 eng自己编译的版本,并使用Recovery清除数据,开机失败

尝试4:fastboot flash boot /path/to/boot.img,并刷入 CM 11 eng自己编译的版本,并Recovery清除数据,开机失败

尝试5:使用Logcat抓日志,输出如下

  这理应是数据没有清除完成导致的,于是 Google下,尝试使用 fastboot -w 来清除数据,最后成功开机!

 

小结,Nexus 7 此类问题解决方法(黄背景的是重点,前两步可选)

  adb sideload /media/Source/CyanogenMod/out/cm-11.0/target/product/flo/cm-11-20141224-UNOFFICIAL-flo.zip 

  fastboot flash boot /media/Source/CyanogenMod/out/cm-11.0/target/product/flo/boot.img

  fastboot -w
