[Q] Can you install a new kernel on Kindle Fire

Hello all,
I'm working on a research assignment for school and I'm a little stuck.
I know it's possible to install a new bootloader on the Amazon Kindle fire.
I would like to do more than that.
I want to install a new or change the settings of the Linux kernel on the Kindle Fire. Why?
I want use the tablet for my own purposes. These purposes mean that I have to control all ports and memory to restrict access.
Can this be done, theoretically?

Bootloaders e.g FFF can be loaded to the boot partition seperatly. The same can be done with recovery partitions and the kernel.

Thank you for this information.
Can I also delete the other bootloader and the Android OS?
I want nothing else on the Kindle Fire other than my bootloader and programs.

You can write FireFireFire or something similar to the boot partition. To run your programs tough you will some version of the Android OS on the device.

You need a factory cable.

You can make one yourself with a little skill and/or ingenuity, or you can check with @SkOrPn (I believe he ships to all over the world).

Since I already see this coming, I'll go ahead tell you where you went wrong and how to avoid it in the future.
First off, there's really no need to "root" your Kindle Fire. The steps required to root the Kindle Fire involve installing custom recovery (TWRP in this case) to gain temporary root permissions so you can push Superuser.apk and the SU binary. However, all custom ROMs come pre-rooted, so rooting beforehand is unnecessarily redundant. Even if you wanted to keep the stock OS, there is a stock based ROM called MoDaCo that will give you what you want while saving you pretty much all the work of having to do whatever you wanted to do with a rooted stock device anyway.
Second, with custom recovery already installed, the only reason to install the 6.3.x software update from Amazon, is to revert the device to 100% stock (i.e. no root, no recovery, no custom bootloader). Where you failed is in attempting to install the update.zip without first doing a factory reset in recovery. The resulting problem will leave you with a device that has no working shell, and therefore no ability to change bootmodes or install custom recovery again.
The factory cable (mentioned earlier) puts the device in fastboot mode where you can reinstall custom recovery, custom bootloader, and change bootmodes using fastboot commands (or some script based utility), then you can use custom recovery to properly install a ROM of your choice (remembering to factory reset). It should also be noted, that you should never wipe anything in custom recovery until you have successfully used it to create a backup. Be sure to save your system partition at the very minimum, and you can always go back to delete it afterwards.

[Q] need help with boot loop

Please forgive my noob-ness. I've done some research but i can't figure out whats up with this device.
I have a Kindle Fire first gen that is stuck in a boot loop. I get the boot logo with "Kindle Fire" and a flicker effect but that is it. This is NOT my device i'm trying to fix it for a non-technical family member. I know they didn't try to root it or any of that. It just stopped working for them one day.
after installing / removing / reinstalling the drivers a million times i finally got the kindle fire utility to see the device as online. its seems like no matter what i do the device goes back to the boot loop and KFU gives me "waiting for device'. anyone have any ideas? do i need the factor cable to get this working again??

according to FAQ 16 Frequently Asked Questions - Amazon Kindle Fire
If the Kindle Fire logo you're talking about flashes and goes dim after being brightly lit for a few seconds, then your device is trying to boot normally to a malfunctioning operating system, likely caused by not wiping the data partition (factory reset) before flashing a ROM. If that's the case, you will likely need a factory cable to get into fastboot mode so you can access or (if needed) install custom recovery, then reinstall a ROM properly.

yes you need a fastboot cable
or

Not sure of the state of your Kindle Fire G1 (It's not rooted? Are you sure?), but this sounds similar to what I ran into trying to install CM11.
What version of TWRP do you have installed? If it's 2.2.2.1 and you're trying to install a ROM with KitKat (CM11) you can run into this. I did. When I installed TWRP 2.7.0.1 I could install CM11 just fine without the boot loop.
To install TWRP 2.7.0.1 I found that you could only do so by:
When you turn Kindle Fire on, hold down the power button to cycle through the options when you see the Kindle Fire logo. You want to land on the Recovery option.
Mount storage from TWRP 2.2.2.1 on a PC and copy CM10.x.x and related GApps to SDCARD
Factory reset then reinstall CM10.x.x (with Gapps for that version)
Install Flashify from the PlayStore
Download the latest TWRP for otter/Kindle Fire G1 (2.7.0.1)
Install it with Flashify
Download CM11 and related ZIPs (GApps kk, Change to Nexus 7, etc) to Downloads directory
Restart into TWRP recovery (should be 2.7.0.1 now), and factory reset/reinstall CM11 and related ZIPs from Downloads directory
Should be fine now.
I found that I could only do it this way because for some reason Kindle Fire Utility Kit and ADB couldn't work with my Kindle anymore with TWRP 2.2.2.1 (don't ask, I don't know why). This way works. Just make sure you have a copy of a version of a ROM and GApps on SDCARD at all times since mounting storage might not work anymore in TWRP (again, I'm not sure why). I tried it again and again, but I couldn't get it to work and it might be the same for you. Keep in mind this is for CM11. If you're using stock, then follow sd_shadow's advice.

Unable fo factory reset or boot into CWM

HI Guys,
I need some help, i cant peform a factory reset or boot into CWM, i was not able to reboot into CWM after the first installation. I rooted my AFTV these are the steps.
1) block updates on router.
2) fire tv running stock version 51.1.0.1
3) rooted fire tv (installed towelroot, supersu and busybox)
4) disable updates via adb on the fire tv
5) partially unlock boot loader
6) install CWM 6.0.5.1.4a (yes i granted su permission)
At this point fire tv rebooted but it did not bring CWM instead it went to straight to normal amazon boot. I tried alt+printscn approach but didn't work. When i try to get into cwm via adb command "adb reboot recovery" it will reboot and for a split sec i see blue screen and but then it boots up in normal amazon menu.
So i decided to do factory rest and start over.....problem is it is not really resetting the box, it takes me to the initial amazon sign in screen, i enter my login info and bang into main menu and all my apps that was there before are still installed.
Good news is i can still adb to the box and have root access.
any suggestion who to fix this?
I am still running on stock version 51.1.0.1 and i have not installed rbox boot menu. Also, i have done rooted 6 boxes so i am fairly familiar with the process and steps to follow.
Thank you

I also tried to upgraded but after the zip file was adb to the box fire tv did reboot but didn't go thru the installation process.
Any other suggestion guys please? I hate to return this box since it has root since it is getting harder and harder to find AFTV which has root able firmware?
I have been trying to get into CWM via "Alt+print Scrn + i" for few days now but without any luck i have tried this with wired and wireless keyboard, I hold these 3 keys simultaneously as soon as i see the white amazon logo and again when i see the colorful amazon log. Am i doing something?
However, when i do manage it get into CWM. What should i do? Should i select wipe data/Factory reset option? Will this take my AFTV to the way it came from amazon? I am still running amazon stock version 51.1.0.1 and fully rooted with Super su and busybox installed.
Thank you

You need to get in CWM to upgrade to a pre-rooted image.
Have you tried to downgrade (reverse) to factory as per above link? That should work without no issues, should bring your box back to stock and you can start from zero again. I done it numerous times however you need to read carefully and follow the guide step by step sending all the commands one by one in ADB

I tried to revert it back to stock following aftvnews guide step by step, read it over and over before actually doing it but on the final steps, AFTV will reboot but does not install the actual files.
i also rooted another box last night and everything went fine so i am not sure whats up with this box.
Thanks

Am I dead? 8.9 won't go to fastboot, stuck in fire animation

I used the KFHD_SRT v 1.2 to flash the recovery with root. Device was rooted and adb enabled. When I first plug it in to the computer, the ADB drivers flash for a second then disappear again.
My other kindle fire hd 8.9 is rooted etc but I did it several months ago, and works just fine with the adb drivers and windows drivers work as well.
I got 1/2 way through the same install but figured out I didn't put the new mod on the device before I got well into the twerp recovery. So I wiped the old one and didn't have a new one. I had saved to recovery, but I couldn't get it to load. So I started searching around.
I was stuck at fastboot mode until I found the utility. I'm sure if I had only used the v 2.1 I would have been fine.
v1.2
http://forum.xda-developers.com/showpost.php?p=33156486
I currently have kffirstaide64 installed, but until I can get back into fastboot mode I don't know what to do.
direct answers as best as I know.
Which ROM or version of FireOS: Whatever the stock os was. I don't remember the version I planned on wiping it. I never got a ROM installed.
Was adb enabled at the OS level: Yes
Was device rooted: Yes
What did I flash: I tried to flash the rocovery with root for KF 7. And I'm afraid I was successful.
