一、 错误提示 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 $ ./flash-all.sh Sending 'bootloader' (3124 KB) OKAY [ 0.310s] Writing 'bootloader' OKAY [ 0.492s] Finished.

二、解决方法 重点在最后一部分，这里的原因是如下，因此解决方法如下 ：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 image-hammerhead-lmy48b.zip里面的也解压出来。还要修改flash-all.bat 否则可能会出现， 1，写入system.img失败之类的（提示找不到或者内存不足之类的） 2，把32G刷成16G（5.x之后的官方刷机包都有这个问题） flash-all.bat里的 fastboot -w updated image-hammerhead-lmy48b.zip 修改为： fastboot flash recovery recovery.img fastboot flash boot boot.img fastboot flash system system.img ::下面是清除个人数据的（双WIPE）。 如果要保留数据升级，则不要下面2行。 fastboot flash cache cache.img fastboot flash userdata userdata.img fastboot reboot
三、警示 这是adb tools的问题，所以不要从第三方处下载该工具，应该时时从官方地址 下载 adb tools。实际上，在升级了官方adb之后，刷入同样的固件，log 就和之前的不一样了。如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 $ ./flash-all.sh Sending 'bootloader' (3124 KB) OKAY [ 0.359s] Writing 'bootloader' OKAY [ 0.511s] Finished.

四、开机无限循环 如上，在刷入 userdata 时报错 remote: 'Bogus size sparse and chunk header'，这是在之前刷入的第三方固件修改了分区设置。因此要先格式化，再单独刷写 userdata.img。youness.net 拷贝。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 I noticed that I had a specific error at the end of the procedure : Writing ‘userdata’ FAILED (remote: ‘Bogus size sparse and chunk header’) If you are facing the same issue, try formatting the userdata partition and flash it separately. I had the issue because I installed different OS on my device that altered my partitions. Boot in bootloader mode with the buttons ON and Volume down – Then format the partition: fastboot format userdata mke2fs Locate the userdata.img in your zip or source files, then flash it: fastboot flash userdata userdata.img Reboot the tablet, now it should boot correctly to the home page: fastboot reboot
