I download the package the factory image from Google .
I entered the fastboot and do things following:
fastboot erase boot fastboot erase cache fastboot erase recovery fastboot erase system fastboot erase userdata fastboot flash bootloader bootloader-flo-flo-03.14.img fastboot reboot-bootloader ping -n 5 127.0.0.1 >nul fastboot -w update image-razor-jss15r.zip
fastboot -w update image-razor-jss15r.zip
At this time ,bootloader seems didn't chaged , it's still grouper not flo.
I modified the android-info.txt to cheat the program and the tragedy start.
The windows remind me there is 6 unknown device. And then it fully bricked.
Now, When I turn on the N7, the screen stay blank.
APX device appear while connect to PC.
Can't enter fastboot mode ,can't enter recovery. even the screen can't be lighten.
Anyone else meet the same trouble or someone can help?
Before this, I have had try the follow tools.
The Nexus7 toolkit--won't work
tegra-android-developer-pack from nvidia website tegra developer tools --won't work
nvflash and wheelie from androidroot.mobi --can't work --(It's a rediculous project I think, If the fastboot work,why we need to flash rom via nvflash)
