[Kindle Fire General] ejrubin:
I am in a similar situation and am trying to work through it. I thought I rooted my device but when I restarted it, it didn't fully load. I've successfully done all of the steps listed in the OP but am still suck in a black screen (it's lit...but it's black) loop.

I believe I have deleted my build.pop file but have a backup listend as build.prop.bak. However, the device is trying to load and is failing. I need to rename my build.prop.bak as the primary build.prop. I have tried to access SU through ADB but am getting "permission denied" almost as if my device wasn't rooted.

I have tried to mount system as RW but I am also getting permission denied.

Any advice. Here is my /system/

EDIT: I have tried to re-root through the method provided as well as superoneclick root, but both have failed because no android system is being recognized. This may have to do with the lack of a proper build.prop on my device.

EDIT2: I figure the above might not be enough information so I will now post what I have done so far to get it bricked, and what I have already tried.

1. I tried the rooting method on rootkindlefire.com and it seemed successful. I then was able to set /system/ as RW via root explorer. I copied a modified build.prop file that is available in the android development forums. However, unfortunately, I believe I may have edited the name of this file or done something wrong in handling it accidentally. Regardless, I pasted this file in the /system/ folder and renamed my original build.prop file to build.prop.bak. I then restarted my kindle fire. Now, it shows the kindle fire screen for a second and then goes black entirely. It is still on (the screen is lit), but the screen is black. It then remains like this until I do a hard reset and then it repeats this process.

2. I have tried to access SU but have been unable to do so. I have been unable to mount system as RW using the instruction a page back. In both situations I get the "permission denied" response from the command line.

3. Everytime I try to root using the method provided in the OP, I get a message saying that it can't find android 2.2 or 2.3

4. I am unable to root again using super click for the same reason.

5. I have otherwise been able to follow all of the steps in the OP successfully, but to no avail. My screen goes black after it shows the kindle fire screen for a couple seconds.

6. Any suggestions would be very very helpful. From my amateur amount of knowledge, it seems to me that I don't have a build.prop in my /system/ but am unable to rename or access my build.prop.bak so that I can set it as the regular bootable build.prop. This is because, even though I thought I had it rooted, I am unable to set the /system/ directory as writable.

7. ANY SUGGESTIONS OR HELP WOULD BE GREAT!
