Yes this tool was made with a backup of the system.img from v7.2.1. It should not matter what version you are currently using. When I made the backup, to confirm downgrade was possible I used a previous backup and downgraded from 7.2.1 to 7.1.5 and it worked no problem.

Question
Hey, I purchased the SkOrPn jig from SkOrPn. I connected it to my hd7 plugged it in fastboot came up on screen windows installed fire as adb but when I try to see if fast is working or use options 1 or 2 I wait a few seconds it says waiting for device and nothing ever happens. I also tried unplugging and re-plugging after it said waiting for device. Any ideas?

I'm sorry to here that, the thing is this tool was primarily made to unbrick your device. Also the only thing this tool does is flash a system.img(and erase cache and userdata is you chose to), so if something was messed with outside the system partition it does no good.

I personally used this tool many times and have confirmed others that have used it with no problems. Now if you could be more specific as to exactly what happened and the reason you were using this tool maybe a solution could be found, in the process helping me and others if there is a problem with it. Lets try to figure this out before claiming it is a "bad" tool.

I can see there seems to be a problem with a file missing(from platform tools of sdk) to allow this to downgrade the system. If someone can point this out please let me know. Although I no longer own the 7" model so I cannot test this myself. That said if anyone would like to take over updating this tool for the 7" feel free.

Hi,

I tried this using the 7.2.1 image on my KFHD 7" and system boots to system recovery mode and will not boot normally.

I then tried 7.1.5 image and it boots up ok but wifi and touch screen is not working?

I tried also deleting the userdata and cache and that makes no difference.

Is there no way we can use this to restore an original Amazon .bin file?

Many thanks

I tried this to restore a demo kindle fire HD i bought from a comet closing down sale. It seems to have worked but for one major issue, the touchscreen no longer works, as above user. Not sure what to do now.

Tried this again using the 7.2.2 system image and now it doesn't even boot.

EDIT: Thanks to longthinkzhang I've solved this problem by flashing the other partitions that he provided.

It seems that amazon has also updated the boot.img and recovery.img with this recent 7.2.3 update. I have someone sending me a backup of the new 7.2.3 system version. As soon as I recieve it I will update the tool.
Check out the OP in a few for a fix with v1.2 of this tool
