I'm trying to root Kindle Fire but it always show "ADB status: Offline" when I start "run.bat". Could you help me out of this problem? :( I tried to plug, unplug, connect, disconnect the Kindle many times but nothing changes. I'm using Windows 7 x86.
I had the same problem with Kindle Fire Utility, and I actually figured this out.
Then, it finally worked -- both drivers were in place -- then ADB showed up as online and I could get root, and do all the other stuff with KFU.
IF you have run the install_drivers.bat file, and still have this.. Few things to do :
1) Reboot computer/Kindle 2) Re-install drivers through KFU 3) Re-install drivers manually.
For those who tried many attempts in re-installing and rebooting but to no avail. This may be an alternative you can consider. This applies to those who ran install_drivers.bat and saw an error message regarding "./android/adb_usb".
This error is caused by our user name in windows which has one or more spacing (e.g. "Home User"). This one or more spacing breaks the batch file written to assist you in installing the relevant drivers.
Solution is simple, edit the install_drivers.bat and include double quotations (" ") to all file paths which has %userprofile% (line 9 & 10)
Before re-installing your drivers, kindly ensure you removed the existing drivers via Device Manager -> Android Phone -> "Android ADB Interface" (or) "Android Composite ADB Interface"
Re-run install_drivers.bat and then run run.bat
Your kindle should be ready for rooting :)
