BurritoRoot is a root exploit for the Kindle Fire, released to gain root on the 6.2.1 firmware. Originally
licensed under a proprietary license, we re-released under the GPL due to blatant code theft by the author
of 'unlockroot'. Not only is he a thief, but a moron, hell he stole the unroot code of our's that was broken.
How it all works
In /sbin/adbd is a secondary property check to see if adbD can run as root, "service.root.amazon.allow". Normally
this can only be set by a system or root process.
<snippet>
.rodata:000203EC aService_root_0 DCB "service.root.amazon.allow",0
.rodata:000203EC ; DATA XREF: .text:0000EFEC�o

.rodata:00020408 a1_0 unicode 0, <1>,0 ; DATA XREF: .text:0000EFF0�o

.rodata:0002040C aAdbdCannotRunA DCB "adbd cannot run as root in production builds",0xA,0

.rodata:00020450 aRestartingAdbd DCB "restarting adbd as root",0xA,0
.rodata:00020450 ; DATA XREF: .text:0
</snippet>
In Services.jar is the BroadcastReveiver com.lab126.services.EasterEggReceiver that allows the above property to
be set with a broadcast from any application.
<snippet>
.method private enable(Z)V
.locals 2
.parameter "enabled"
.prologue
.line 47
if-eqz p1, :cond_0
const-string v1, "1"
move-object v0, v1
.line 49
.local v0, value:Ljava/lang/String;
:goto_0
const-string v1, "service.root.amazon.allow"
invoke-static {v1, v0}, Landroid/os/SystemProperties;->set(Ljava/lang/String;Ljava/lang/String;)V
.line 51
return-void
.line 47
.end local v0 #value:Ljava/lang/String;
:cond_0
const-string v1, "0"
move-object v0, v1
goto :goto_0
.end method
</snipper>
After causing this property to be set, the user can simply do "adb root" and then adbD will run as root.
