I think i've found the script(?) which i used to root my kindle fire.. it include an unroot option but if i execute it.. i recieve an error, so i opened the runme.bat in txt:
:UNROOT
set /p unr=Really (y/n) ?
IF %unr% == n GOTO CHOICE
stuff\adb.exe push stuff\busybox /data/local/tmp/busybox
stuff\adb.exe shell "chmod 755 /data/local/tmp/busybox"
stuff\adb.exe shell "su -c '/data/local/tmp/busybox mount -o remount,rw /system'"
stuff\adb.exe shell "su -c 'rm /system/bin/su'" <------------------------------------------------------------
stuff\adb.exe shell "su -c 'rm /system/app/Superuser.apk'" <------------------------------------------------------------
After I ve done a factory data reset, i 've installed ROM TOOLBOX on the kindle fire and delete i've manually deleted the 2 files and other file which i've converted to system app.. now.. what should i do to check if the device is still rooted?
Sorry again for my bad english..
PS: I don't think i've unrooted the device becouse i can still use ROM TOOLBOX
