I suspect we are about 6 to 8 months away from seeing custom ROM's (if we use the past as an example). The utilities you mention FFF and TWRP were designed around a completely different bootloader - Kindle Fire (Original). There is a group working on a new Bootloader named "Safestrap" but the project is on "Hold" at the moment: http://forum.xda-developers.com/showthread.php?t=1965045
What we can do until that time is Root the Kindle, install Google Play and an assortment of Google Applications. You can also give your Kindle a facelift by installing a new Launcher like Go Launcher: http://forum.xda-developers.com/showthread.php?t=1915493
Enjoy.

Is my Kindle Fire HD (7.2.1) unuseful now?

Hi all, I'm posting after weeks lurking here how to make my Kindle Fire HD 2 a real table. I followed many steps but now I can't even switch on the kindle so I ask you if I can solve my problem.
The kindle I have is the Kindle Fire HD (I guess 2) with Microphone and Webcam. The Version is 7.2.1
At first I rooted the device using the instruction on this page:
http://forum.xda-developers.com/showthread.php?t=1891939
Eveything worked and not without any effort. I had to install the Android SDK and test many times the adb tools.
Before that I tried the KUF 0.9.6 but didn't work.
After the rooting I wanted to install TWRP, my purpose is to have a tablet with Android.
I followed the instruction on this page: http://finditmore.info/2012/09/19/install-team-win-recovery-project-kindle-fire/
I guess here is the mistake. I downloaded the twrp 2.3 and firefirefire 1.2 and installed as wrote in that page, but now I can't switch on the kindle. Really is like death.
Could anyone explain me what I did wrong? Could I still recover the tablet?
Thanks in advance

The post you linked explains a method for KINDLE FIRE 1ST GENERATION, there's no possibility for now to get a recovery working in our devices regardless of whether the device is a Kindle Fire HD or a Kindle Fire 2. So, you probably bricked your device. From my point of view you only have 2 choices: You can retUrn it to Amazon and pray, or you can try with this method: http://forum.xda-developers.com/showthread.php?t=1951254.
But please, read everything before doing anything.
Hope it helps

Thanks. I'm downloading the system from the thread you pointed me out. But what make me very disappointed is the fact that the kindle isn't switching on anymore. This is really odd.
I'll try to fix it if I can't I'll send to amazon and I'll pray.
Anyway, where are the instruction to flash the Kindle HD 7.2.1?
Thanks!
There is no way you can get your device working now. As far as we know, only Amazon has the ability to fix a second generation device that has an unsigned bootloader or recovery installed.

Is a 2nd Bootloader possible?

With the Kindle Fire 8.9" 2012 device name Jem, they had to use a second bootloader to get around amazon's locked off one. Has a second bootloader been pursued for this tablet yet?
And now that I have root how do I move my google now launcher to the system folder?

I am not experienced with that yet, so I cannot answer your second question, but as far as the second bootloader goes, I have not heard anyone mention that yet... Currently people are talking about using flashfire, so if that doesn't work, I am sure some devs will start pursuing this new direction. Thanks for the idea!
Search the forum for safestrap. There's been lots of discussion on the subject. In short, it depends on working kexec, which we do not have yet although progress has been made.

Installing custom rom with FireOS 5.3.1.0

I have FireOS 5.3.1.0 on my 5th gen Amazon tablet and I want to put Cyanogenmod on it. I understand that I need to first go back to 5.1.2 in order for TWRP to work but I'm also seeing reports that going back to an older version bricks the device. Is it possible to put a new rom on this device? If so, does anyone know where I can find a how-to?

- 5.1.3 can be successfully rolled back to 5.1.2
- 5.3.1 is new; consequences of a rollback attempt are unknown
- twrp is not an option (period); you'll need to use FlashFire for managing custom roms
I tried, despite the warnings, and with knowledge that it could be "fatal", to put 5.1.2 on a 5th gen Fire that had 5.3.1.0 on it. It's now bricked. Only comes up to the MediaTek MT65XX PreLoader, loops on that, never shows anything on the screen. Don't do what I did.

Thank you for sharing your findings. This small, selfless act will help others avoid a similar outcome. A respectful head nod to your device for paying the ultimate price.

It may still be possible to re-flash 5.3.1 bootloaders via AFTV2 tools ... But right now the best route is to talk to Amazon

F&$! Sorry about that Keith. I also have a Fire 2015 with 5.3.1.0 on it and Android 5.1.1 and I've only been able to put google apps on it and not been able to root it at all. I think you may be able to save it. Let me know.

What about going from 5.1.4? Will that brick my device? I wanna downgrade and root it.

I bought two tablets during Prime Day, both came with 5.1.4. I mistakenly accepted the OTA system update for 5.31. on one of the tablets, and couldn't find a way to root or downgrade (I was only able to install google play/apps). After doing a factory reset, I exchanged it at Best Buy (no restock fee!) for a tablet with 5.1.4.
I have since successfully downgraded both tablets to 5.1.2 using RootJunky's tools (Search YouTube for a video by RootJunky titled "How to Firmware Restore or Unbrick your Amazon Fire 5th gen Tablet "), and then I followed the steps from talesofatech.com from the articles list below, to root and flash to an AOSP rom.

NOTE: the above statement refers to downgrading 5.1.3/5.1.4 -> 5.1.2. It does NOT apply to higher versions of FireOS. At this time there is no option to downgrade 5.3.1.x to a lower (rootable) version. Any attempt to do so will likely yield a brick.

Many people have done that (I am one). I think it's misleading to have 5.1.3/5.1.4 posts in the 5.3.1.x thread.
Read the warning too late about the 5.3.1.0 OS and now my Fire HD 8 tablet is bricked. Any one know how to get it back working again? It was 5.1.4 just the other day and I decided to downgrade today, but did not think of checking the OS version and end it up bricking it.

Hey that's awesome. Mine came with 5.3.1 also. Can't root yet but I have google play store etc... I have a rooted Kindle HD I bought in 2012 I actually like a little better than this new one that's rooted. Hopefully there will be an update for the 5.3.1 someday. I'm glad you were able to get those down graded, it sure feels good when stuff just works right !!

Suspect that was one if the first things tried as there is typically no risk associated with root attempts (the payload included with some rooting apps is another story). Beyond that several have analyzed the security 'fixes' incorporated into 5.3.1 and concluded previously leveraged exposures have been closed while others have yet to be exploited. You can bet Amazon will be working to close those too.
argh... received a 5.1.4, and red to late the downgrade option to root. Tried King root, it said a root option would be possible. So I upgraded the fire tablet to 5.3.1.0 in two steps und tried in both king root... nothing worked. So I also have to wait for a new freaky instruction to root a fire 5.3.1.0

Welcome to Amazon's world. First rule: never update FireOS if you care about root (there are exceptions; too many caveats to detail). Second rule: ask before acting as likely someone before you has fallen into the firery pit and has a helpful tale to share.
In your case FireOS 5.1.4 was just fine - could be rolled back and rooted. 5.3.x not so much. Live and learn.

kinlde fire hd (4th generation) need help

So with root tools I broke my fire-ish. I got past a endless reboot, and I do have root. Can someone give me a copy of the 5.1.2's system menu? The broken part is probably named something like amazon launcher, or fire launcher. Something along those lines. Or what ever apk is responsible for giving the fire its launcher aka main menu past the lock screen functionality. (where you would choose apps. games books ect.)

Given you don't know what else is busted suggest reloading FireOS 5.1.2 from stock recovery and then reroot.

Help unrooting kindle fire

I have a kindle fire that used to belong to my brother and he had it rooted. I did a factory reset and upon registering the kindle it throws me into a language selection loop. I can still manage to get into apps, settings, etc.. if I click fast enough before the language selection pops up again. I'm assuming this is happening because it is rooted and I deleted files that were needed with the factory reset. I believe it's a 3rd gen kindle but I don't know how to be sure. Current version is 13.3.2.3.2_user_323001720 Build date Sunday, June 1, 2014. I prefer it to be unrooted for a fresh start but if it's easier to get past that error loop I'll take it. Can anyone help me with this please?

Sounds like you may have a 3rd gen HDX. You'll need to identify the exact model as recovery procedures differ among the various fire devices.
Bumping this to see if I can get any help on it. I have decided to try again after finding my tablet. The tablet is a Kindle Fire HDX 7 3rd gen. After researching for a while I found out my brother rooted it using SuperSU as there's an su file under system/xbin (my brother doesn't remember anything) but no SuperSU app installed due to the factory reset. I was able to solve the language selection loop error but now I'm stuck on what to do next. Some apps work some don't. I just want to be able to use newer apps/games. Would you guys recommend trying to unroot or can I update current root to something not stuck in a 2014 update?

I would suggest go to amazon and download the full update. Also there is a hdx thread that might be more relevant. I do not have one of these devices and this thread is for the fire 7. See the next post...

Reloading FireOS (any build) is not an option on unrooted HDX device. Also rather dangerous without an understanding of compatible versions; a difficult to correct brick can easily result. Re-ask your question in the HDX help thread; someone (most likely me) will respond. You'll need to do a fair bit of work to restore that device including unlocking the bootloader and installing a custom ROM. Not for the faint of heart.
Thank you guys!
