At least on the HD you can flash anything with fastboot -- but if it is unsigned, it will fail to boot up (or sometimes actually just refuse to flash it). If it's properly signed, it should boot up.

I don't have an HDX to test with, but it seems to me like flashing the boot.img from an old update *may* work -- while you might not see anything on screen/some hardware may not work, you should be able to connect through adb and use the same old exploit -- and then revert to the newer kernel to get everything functional again. Again, I have not tested this so I cannot confirm it works, and I am assuming that fastboot would work. It is possible that it does not work as GSLEON3 described.

Similarly, you may have some success making a stripped down system.img that contains a su binary and flashing it, like I have done on the HD (again, no clue whether this will work on the HDX or not)
[Kindle Fire HDX 7" & 8.9" General] Mineturtle33:
So this won't work?
[Kindle Fire HDX 7" & 8.9" General] Gran PC:
It *may* work if you use boot.img and not boot-prod.img (which doesnt exist), but it's probably not going to work.

I tried to flash boot.img from the 14.3.1.0 bin file (Fire HDX 8.9) and unfortunately it didn't work. Attached is a screen capture of the command line output.
[Kindle Fire HDX 7" & 8.9" General] ferrouskid:
Here is the BIN file straight from amazon website couple of months ago, the 13.3.1 "update".

https://www.dropbox.com/s/98f9yxbmekwtxi2/update-kindle-13.3.1.0_user_310079820.bin

Also, I entered fastboot mode, but without a factory reset cable, my kindle displays KINDLE [fastboot]

and READY

but as soon as I attempt to flash boot.img file it says waiting for device...

Should I try with fastboot cable?

With it all that happens is the screen goes black, but I can hear it working, and it does indeed run out of battery.This is from previous experience of trying to unbrick it.
[Kindle Fire HDX 7" & 8.9" General] ggow:
ferrouskid, it might be that you don't have your drivers set up correctly. When in fastboot your kindle should show up in device manager on windows as an Android Boot loader interface device.

I didn't use a factory cable, just a cable I have spare. I got a response from fastboot mode but flashing boot.img failed because the hardware/bootloader is locked down. See the attached screen capture on post #15.

I forgot fast boot can't flash images >900 mb. Hmmm.
[Kindle Fire HDX 7" & 8.9" General] Gran PC:
It probably won't let you flash any image at all anyways. Else I could just make a reduced system image (the one I made for the HD 7 is 69 MB) that would give you root access.

btw

for those of you who did not already know it is really easy to enter fastboot mode rOM Toolbox ..add reboot widget..or any app. that will allow you to hit reboot into bootloader option....and my s4 cable allows PC to recognize as fast boot device..not cable that came with kindle. however there isn't any yellow triangle... Simply a grey Kindle Fire across top , with [Fast boot]. Just below. And serveral lines down It states "offline" until I plug into PC with my s4 cable. Then states "Ready," PC states "fastboot device". Seem a little bit different from what other people are describing as fastboot mode with a yellow triangle and the computer reading it as an ADB interface.....I hope this help somebody get somewhere with this

Btw do you have abd installed? One thing I would really suggest is "Minimal Fastboot and ADB" application, it weighs 2MB (apparently) and is very good, install it and see how it goes. There are a load of very useful things you can use it for, like unblinking and flashing rooms, so get it. There is a thread somewhere here on xda about it.

The title of this thread says 13/14.3.2.1 therefore it is for the 7 and 8.9.

As for the method of rooting referred to by the previous poster, I was totally unaware of this root method though I do not see anywhere in the post that it is for the new update which is 14.3.2.1. Can anyone confirm this does or does not work on hdx 8.9 new update 14.3.2.1?

Do you have the bootloader unlocked on this device? Need workaround? Get ready for some development here in a bit. If you got root, thats good, but that build from android cyanogenmod is just floating on it. I am looking at calling some nook color devs in here for some kernel work. Ok then.

I am young, but I don't play. PM me with some followup and send me a device and I will unlock it. Ok then. Check creds and its go time. *firing up wireshark in terminal* I need device. Hit me. Linux chixs. Take note. Got piledriver on AMD? I do. 16 cores. LOl yep its watercooled. Ok then.

I haven't done much on this lately as work has been keeping me busy. I have a full setup & have worked wit/tested for Hashcode & jcase on the initial root exploit, which Amazon of course patched. There are quite a few quirks with the device, as you'll learn once in hand. While I have no doubt you have 1000x the ninja skills I do (after all I'm an engineer, not a software guy), if you have an basic questions about the setup or you need something tested by someone that can pull & understand a logcat, lmk. I also won't sweat it if I brick my device.

Wish you all the luck! I am certain there are exploits there, but some of the routes have had unacceptable consequences for my usage type, like loss of Amazon Video, etc (likely from some component in trusted zone looking for a resource I modified, breaking drm & dhcp).

Note

For the retired enginner.

Just take your time. It took me about 6 months in my spare time from school. Do not get upset. Let the younger enginners carry the brunt work. Do not forget to make rules to block IP addresses through the IP tables pulled on the Amazon kindle fire from their servers. Assemble your team to help you up in IRC. It looks like you are getting close. Remember up in nixcraft? They have that information. Look online. Just a hint out for your team from picking up those RSA encryption keys from there. If you are assembling one. Our enginners worked together up in the nook color in IRC channels. Here is a link out for your help: http://nixcraft.com/showthread.php/1427-iptables-ip-address

You will have to use nmap to get all of those IP address from the Amazon servers generating those keys. And make exceptions for those rules. Remember that bootloader has those keys served up. Those keys might be stored in the flash memory of that device so check that over for abit. If you guys are this far. Copy and paste for references if needed. One of your team members will have to set up a github account for that reworked code for the amazon kindle fire, if they are not there. And push it to the github.

_______________

Ok I got a note in. I am not too sure if those servers are static, We will have to sit on those IP addresses and see if they change any. I think they are dynamic IP tables, I will look into it today. Does Apache servers change IP tables? Sometimes? I think Amazon are on cloud servers, Have one team member check it over. I am smart, but I am still learning. I am not a genius lol. I will look into it also. The kindle fire might have a private: :public encryption on that bootloader in ssh. It might hold the private one. Or public one.

Hit his donation box for me. Good tip for your team.

Man you need to get on the Verizon galaxy s4 bootloader unlock
[Kindle Fire HDX 7" & 8.9" General] ggow:
Hi ferrouskid,

Try the following:

1. Get yourself the google usb driver (which is the one I used) and extract it to the desktop.

2. Connect your Kindle HDX with fastboot enabled with a standard micro usb cable.

3. Assuming ADB is working, at cmd prompt type "adb reboot bootloader" <enter>

4. Your device should reboot into fastboot mode and the screen should look like the attached screenshot (fastboot_hdx8.9.JPG)

5. Open device manager on your PC and find your Kindle, your device should appear as an "Android Bootloader Interface Device" as in the attached screenshot (windows device manager.PNG).

6. If it does not then you need to install the driver from the package downloaded in step 1. The Kindle may appear in device manager as an MTP device or adb device so find out which it is.

7. To install the driver, you first need to uninstall the existing driver (this won't mess up the adb driver so don't worry). So right-click on the device in device manager and select the "Uninstall" option.

8. Then on device manager press the scan for hardware changes button, on windows 7 it's the last one on the row.

9. An uninstalled device will appear.

10. Right Click on the device, select Update Driver.

11. Click the "Browse my Computer for driver software" option.

12. Then click "Let me pick from a list of device drivers on my computer"

13. Click on the "Have Disk"

14. Browse to the google driver you extracted to the desktop.

15. Select Android Bootloader Interface for installation.

16. Then test fastboot by issuing the following command "fastboot -i 0x1949 devices"

17. You should then hopefully have it working.

Let me know if you get it working...
[Kindle Fire HDX 7" & 8.9" General] GSLEON3:
I have been pretty tied up working on several university & hospital projects, so I haven't really kept up, or followed thru on any of this.

It has been a while since I looked at the bootloader & it's possible I could be wrong, but I think this is the first Amz device that is NOT Uboot based. Now I am not 100% certain on this, but I looks to me like they are generating the signature for the update using apksign. That may lend itself to a workaround for a downgrade.

Another thing, if you look at the recent update for the HDX 8.9, you see they use two boot images. boot.img & dkernel.img. I didn't think apksign used RSA, but it's been a long time since I paid much attention to it & I don't think I've ever seen a full update signed with apksign before. At any rate, if you can preserve, or re-generate the apksign signature, you may be able to swap the updated boot.img for the dkernel boot image & then reflash the 3.1.0 firmware (with a modified build.prop) as a temp work around. I have never seen anyone control access to the bootloader or fastboot via a kernel. really don't think it's possible, though maybe the secondary boot image allow access to the misc partition or a secondary "trusted zone-like" area where the keys are stored. Since they seem to also incorporate stream writer for SOMETHING in the update (sed for those that don't know) maybe that data is then being injected via sed. It is definitely an odd way to structure updates, but given the numbers originally projected, I doubt they are storing in AWS. Analyzing the mbn or even some of the broadcast cert dat data. SED is definitely there to inject something somewhere.

Another thing to analyze, is the data in the fwupdate tarball. From what I can see, that does not appeared to be signed in the same manner. Maybe extracting the yaffs images may shed a little light. Just weird stuff. Boot.img, dkernel.img (another boot.img) & within the fwupdate tarball, yet another boot.img (boot-oe-msm9615.img). Is it possible that the production bootloader is hobbled & they are using a yaffs image to temporarily open access? I don't know. Too much going on for such a screwy way to approach updates.

Keep trying. You will have to collect data packets with the wireshark tool I gave out in my signature to unlock that bootloader. It will take a few weeks of collecting packets. Don't have the device on a secured network.

BTW hot tip: Those software enginners over at texas Instruments hang over at beagleboard.org. They sometimes will drop of hints in there. Isn't the processor chip and board for this device made from that company? Worth a look. Some software enginner that might be looking in might want to take a peek and look over there for intel.

Check on specs for this device today. It looks like they don't. Someone could be looking at this device over there, even though. < idoims >.
