[KFHD7] Stock 7.4.3 - Can't get into fastboot

Hello !
I got a new Kindle Fire HD 7". I updated the firmware to 7.4.3 (still unrooted).
I installed the ADB drivers (here or here), followed the Amazon procedure, read all the FAQ... and then I can't even boot the device in fastboot mode with the following command :
fastboot -i 0x1949 getvar product
When I enter the command, "< waiting for device >" is shown. Then I plug the USB cable, the device starts and boots into the stock ROM.
ADB is working (adb devices returns my device). ADB is enabled in the security settings. "Android Composite ADB Interface" is shown into the Windows device manager.
I rebooted my computer twice. No change.
EDIT : adb reboot bootloader restarts the device in stock ROM too.
Anyone got an idea ?

If I remember correctly you need to be rooted first or have a fast boot cable. If you root it try running adb shell su -c "reboot bootloader"
Just curious why are you trying to use fast boot while on stock unrooted?

Good call. Pretty much anything you do in fastboot without the 2nd bootloader installed will ruin your device.

I want to use fastboot to install the 2nd bootloader. I'm following Hascode's instructions and seokhun's instructions. Checking if fastboot is working seems to be STEP 0 in @Hashcode post.
The "Amazon OS 7.4.3 pre-rooted" is downloaded in STEP 2 : it's strange because it seems root is required in STEP 1 and I don't know if this zip file is flashable at this point.

I don't have a fastboot cable (yet). I'll try to get my device rooted and try your command.
Thanks for your help !

[Q] 7.4.6 - two questions

Hello.
After hours of struggling and Googling (and reading mostly from this forum) I managed to root my KFHD 7.4.6 using bin4ry method. I have two questions about where I'm at right now.
Question 1: While struggling to get adb to recognize my KF, I realized that the problem was quite simple: after installing the special adb drivers, I would plug the Kindle back in and Windows would recognize the device and install the Microsoft drivers - completely ignoring the driver I had just installed. The only way I managed to get around this was to quickly interrupt Windows 7's driver installation and tell it to NOT install drivers from Windows Update.
However, I'm sure there must have been a more elegant way of accomplishing this. What would have been the correct way to do this?
Question 2: Now that adb finally recognizes the KF, and the KF shows up as "Android Composite ADB Interface" in device manager, I want to put Android 4.2.2 on the KF - so CM 10.1. I'm doing preparatory research so I can learn about what I need to do. The big concern for me now is that my KF version is 7.4.6. There seems to be relatively little information about this, and I've seen it explicitly indicated in a few places that only versions before 7.3.something have the exploit available. Does this mean I must first downgrade from 7.4.6? I've had trouble pinning resources down that would help me answer this question - so if anyone has any solid tips about this, I'd appreciate it! I'd really rather not brick it :silly:
Thanks! :good:

I just found this:
http://forum.xda-developers.com/showthread.php?t=2271909
So the answer to my question appears to be "YES", correct? It appears that I need to flash back to 7.2.3?
Question 1 still remains unsolved.

Well you could downgrade it, I don't know if the latest update causes problems, but the thing that needs downgrading isn't the os, its the bootloader. I suggest the fireflash method in seokhuns tutorial, the one you linked. Just make sure to check the first box at the top in fire flash or you will have a red screen brick, which requires a fastboot cable to fix. Also I have never heard of windows update having drivers for the kindle, I mean I usually hit skip anyways, I believe the more elegant solution may have come with kindle fire first aid, not positive though.

I'm having another little inconsistency now.
I disconnect and power off my KF.
I run in cmd: fastboot -i 0x1949 getvar product
It says < waiting for device >
I then plug in my (powered off) KF, and it boots up NORMALLY, and fastboot doesn't return the expected tate-xxx.
Any ideas why?
My ADB is seeing the device. (ie. adb devices is returning one device).

Your fastboot drivers aren't working.

Indeed. Can this be solved by wiping existing drivers and reinstalling Amazon's USB drivers from sdk/extras/amazon ?
EDIT: I've attempted reinstall twice with no improvement. ADB works, fastboot won't.

Um I thought that command only worked on a 8.9" kindle to get it into fastboot.try this instead:
Adb shell su -c "reboot bootloader"

Interesting. I tested that. adb shell su -c "reboot bootloader" does indeed put my device in fastboot mode, and fastboot -i 0x1949 reboot takes it out.
Interesting. Seokhun's tutorial seems to indicate that fastboot -i 0x1949 getvar product should do it as well... so it seems that my fastboot drivers are... kinda half working? Or something?

That option may have been removed in later versions of the bootloader. Some have had success with it while others apparently haven't. If the reboot command works, your drivers should be working properly.

Sounds good, thanks. I'm following that tutorial even though it's for 7.4.3, and I'm on 7.4.6. I hope that doesn't cause any issues - but 7.4.6 looks like it's pretty new, so I don't see other options.

Ok - I've followed the aforementioned tutorial precisely up to step 4. When I try to boot the kindle up, it shows orange logo, then blue logo, then looks like it's trying to boot normally, then sends me into TWRP.
Is this what is called "boot loop"?
At this point my PC doesn't see the sdcard so I can't get CM/Gapp copied over.
Would it be safe to push CM & Gapp to the sdcard using adb, then resume with TWRP?
EDIT: Still can't boot into the system. Just sideloaded CM 10.1 ROM onto the sdcard. Safe to continue with Step 4, wipe stuff, and install the CM rom?

This ended up working.
However, now with CM 10.1, my PC isn't recognizing the device for MTP. It still does recognize it as an ADB device, but ADB doesn't see it.

Odd that MTP isn't working, u can always switch to pptp mode if that helps, but everything goes to the dcim folder on the sdcard.

Got it working. Basically just uninstalled the existing drivers and reinstalled standard drivers. Works like a charm. I love CM, this is great! Thanks all, for the help!
I'll worry about getting adb going again later.

[Q] KFHD 2013 boot loop

I tried to remove the ads from my KFHD 2013, and only found out later, that the tool I used was intended for the 2012 version only.
My kindle is now stuck in a boot loop. Can you help me to fix it? I'm not sure which tool I can use, for the guides here in the forum usually don't mention which version they require.
The fastboot mode is still working, however the adb driver seems to be unable to find my device.
thanks!

Adb commands don't work with fastboot mode, only fastboot commands work with fastboot mode, like
Code:
fastboot -i 0x1949 getvar product
There is a utility that will reflash your system to stock in the general section. Don't use kffa with your device though.

ADB works, but fastboot won't recognize device. Can't update TWRP to 2.7 for kitkat

edit : crap ..... worng section ... how do I delete ?
Hello.
I have a KFHD 7" happily running under Hashcode's CM10.0. I'd like to update to kitkat.
For that, it seems I need to upgrade my recovery from TWRP 2.4 to 2.7. ( If the rom should install under TWRP 2.4, let me know, cause I got an error when I tried. )
So, after messing a bit with my drivers, I got ADB to work fine.
However, I need fastboot to update recovery. My Kindle can go into fastboot, no problem.
But windows just won't recognise it. "Fastboot devices" always show no devices connected.
I tried with various drivers ( including those from QEMU thread ) on 2 differents computers.
So I'm starting to wonder if there is something I missed in the virious threads. Is there something I should know that would prevent me from seing the device under fastboot but not ADB ?

If you have the image,try using FireFlash by stanga72. Just place the image on the sdcard,open fireflash,select "Flash Recovery" and choose the image. Hit Flash,and reboot into recovery.

For some reason, Kindle devices won't be recognized in fastboot without the specific flag "-i 0x1949". For example, "fastboot devices" becomes "fastboot -i 0x1949 devices" and "fastboot flash recovery recovery.img" becomes "fastboot -i 0x1949 flash recovery recovery.img".
I'm positive this is the issue.
Have a nice day!

Installing KK on KFHD, too confusing, help appreciated

Hey guys, I've got a KFHD 7" running system 7.4.9 and I was able to root it today successfully and I would like to install the LiquidSmotth 4.4.4 ROM on it.
The problem that I'm having is that I need a recovery likw TWRP 2.7+ but the instructions are way too complicated and they mention a 2nd bootloader which requires a special cable, what the hell, is it that complex?
I appreciate if anyone can point out a more human way of getting TWRP 2.7 or CWM for KK on my Kindle v 7.4.9.
Thanks!

Alright. Let's get you started.
First of all,use the Kindle fire system restore tool to downgrade to 7.4.6 OR 7.2.3. Either will do. Next,root it using the Bin4ry tool and download the TWRP 2.7.0.0 image with the freedom boot image that is corresponding to your software version. Then,flash them using FireFlash or Flasher or manual method.
Bingo.

Hi man, I'm getting "No such file or directory" when I try to reboot in fastboot mode, here's the output:
Code:

So I ran it again and it kept says "waiting for device", my Kindle is rooted with "Mulai Root" and I used root checker to confirm that it is rooted.
I turned the Kindle off.
I issued the command on the command prompt.
The command prompt said "waiting for device".
I plugged in the USB cable.
The Kindle turned on.
The Kindle booted all the way to the launcher.
The command prompt kept saying "waiting for device".
I would appreciate any more ideas.

Yes, I just installed and ran it using root access. But I'm running system 7.4.9, what should I do now with the app open to downgrade?
The program states "Warning: current bootloader is not kfhd7-u-boot-prod-7.2.3.bin"

Can you help me using FireFlash to downgrade?
Thanks

The culprit was the chinese or vietnamise root, I rooted again using qemu and now I was able to boot into fastboot mode.

I hae a big problem, I sued the Kindle Fire First Aid to restore to 7.2.3 and now my kindle stays on the boot logo.
How can I restore it now?
EDIT: Never mind, it actually booted up.

Hey, I managed to get downgraded and now I'm on this part:
TWRP 2.7.0.0 image with the freedom boot image that is corresponding to your software version.
I'm confused if I should install a 2nd-bootloader or not, I installed fire flash already, let me know if you can help me with a link with the next steps to perform.
Thanks

I think I kind of managed to do it, the problem now is that TWRP loads but the ROM I flashed didn't boot (Liquid Smotth 4.4.4), I'm going to start a new thread.
Thanks
