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.
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?
Update: problem fixed. I took your bat the gx.jar and the images folder and placed them in the platform tools folder and viola. Great tool. Thanks for your time and effort

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

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
Thanks that solved it as I had already updated to 7.2.3 before trying 7.1.5 and 7.2.1 things weren't playing ball.
If we had a 7.1.5 boot.img and recovery.img could we downgrade?
As far as I can tell 7.2.3 firmware Amazon is also editing iptables and thus bypassing any firewall we may have in place... so we still can't easily prevent OTA updates which is nasty.

FIXED i flashed the boot.img and recovery.img from the first post and touchscreen is working i know have a fully working kindle that was a store demo version
Any word on the 7.2.3 update? I just got a KF HD 7" which came with 7.2.3, and I have a factory cable on the way. I want to root, but I kind of want to make sure there's a way to recover if something goes wrong. Although if downgrading to 7.2.1 is a safe way of recovering, I might go ahead and root...
Is there any benefit to running 7.2.1 over 7.2.3?
I'm willing to help if there's any way I can.

I'm still waiting on the back up from someone. Got a pm that they were uploading it now.
No there is no reason to stay on 7.2.1. As long as you can root it would seem better to have the latest version.
I'll let you know if there's anything you can do

Hi onemeila, I thank you so much for putting up this helpful thread. I used it to downgrade to stock 7.2.1 after i messed up my daughter's KFHD 7. And I also learned a good deal and had fun while going through the process.
May I suggest you re-write this as a " Step-by-step HOW TO" guide for such noobs like me as most would find it confusing figuring out the first step to do. Once again, a hearty THANK YOU!
Yeah I was planning on doing that with this next update. It all is seeming to get a little jumbled. Thank you for the input though.

78KINDLE FIRE HD ONLY!!! USE AT YOUR OWN RISK!!
I put together this tool for those that have tried to modify their system unsuccessfully and bricked their device. You must be able to get your device into fastboot for this to work. The easiest way is to purchase a factory cable or make your own(a $15 purchase or a little bit of your time is better than a bricked device).
The .img's in this tool were made from a rooted device w/ the su binary in place. There is no need to re-root your device, however if you choose to erase cache and user data(not necessary but may be a good idea) you will need to re-install Superuser.apk to gain root.
Instructions:
1.) Download the version you want to use from the link below and unzip.
2.) Enable fastboot mode. Turn off your device then plug into your pc using a factory cable. If the device is recognized by adb then you can use this command:
3.) Run the SR Tool.bat and follow the instructions. If you wish to downgrade system versions see instructions at the bottom of the post.Code:adb shell su -c "reboot bootloader"
Downloads:
KFHD_SRT_v1.3.5- 7.3.0 (seperate option for restoring factory recovery)
KFHD_SRT_v1.3.0- 7.2.3 (separate option for restoring factory recovery)
KFHD_SRT_v1.2.3- 7.2.3
KFHD_SRT_v1.2- 7.2.1
KFHD_SRT_v1.0- 7.1.5
I apologize for the size of this tool. The .img files used are rather large. If you want to use your own backup .img then download the lastest version of this tool from here. Just place your system.img inside images folder. It must be named system for option 1 or system2 for option 2

Instructions for downgrading to 7.2.1:
1.) Download boot and recovery imgs(these are backus from 7.2.1) from this LINK and place in the folder where you have access to fastboot or inside the KFHD_SRTool_v1.2 folder
2.) Use KFHD_SRTool_v1.2 to flash system.img.
3.) Erase userdata and cache
4.) Open a cmd prompt from the folder where you placed the previously downloaded .img's.
Use these cmds:
5- Reboot.Code:fastboot -i 0x1949 flash boot boot.img fastboot -i 0x1949 flash recovery recovery.img
Those who deserve our thanks:
kinfauns for the how to on backing up and restoring system software.
bazm60 for confirming the method above works.
hellocali626 for bringing to my attention the need to flash boot and recovery images for downgrade.4
All you can do is fastboot commands while in fastboot, which is all you have access to atm. You no longer have adb nor do you need it atm. When you restore, you will. Red screen when using FireFlash is from not ticking the stack override box before flashing. Just use the System Restore Tool and flash your tablet to stock and start over. Your tablet is recognised in fastboot and should be recoverable.3Uploading the 7.4.9 rooted stock images now.

No I do not mind, lol... However, I do not own any of these devices and yet people keep asking me if it will work on their device. I keep seeing different reports on the subject and do not want to be giving out false hope. I will update my list of confirmed devices.
Thanks for all the work you do to help the Kindle community :good: and thanks for the positive endorsement on my Factory Cable...
Best Regards
