Thanks for your great tutorial, everything worked fine.

As I’m pretty new to Kindle roots I got some questions, would be great if someone would be so kind to answer them.

Is there a description how I unroot and un-savestrap the Kindle? (kind of restoring the factory defaults)

Can I use the stock rom in the stock rom slot as usual or should I create another slot with the stock rom (Stock Rom + Rom Slot 1 [custom rom] + Rom Slot 2 [stock rom which would be used from time to time]) to prevent bricks?

A bit off topic: If I want to delete the User-Data on the stock rom slot and on the custom rom slot (Nexus V2.0.1) can I simply use the “Restore to factory defaults” function in both the stock rom and the Nexus rom? Or would this brick something?

Thanks :)

Safestrap APK Installation without enabling WiFi

Those of you who just received their Thor/Apollo, updated them to 1X.3.2.4 according to this tutorial and rooted them might want to sideload the 3.75 Safestrap, since the KFHDX toolkit only contains an older version of sidestrap. According to this, the Installation of a file manager through the Amazon App Store is necessary, which enables you finally to sideload the APK.

I prefer sideloading Safestrap before the device gets personalized and registered with Amazon. This is easily possible through a tool called "APK Batch Installer Tool" available e.g. at chip.de. The tool just uses the ADB driver you have already installed with the KFHDX toolkit.

This way, the devices do not get personalized and registered with Amazon like it is automatically happening when turning on WiFi the first time. No necessary installation of a File Manager through the Amazon AppStore. You can use Safestrap to create a clean backup before the device gets registered with Amazon.
[Kindle Fire HDX 7" & 8.9" General] taette:
Good idea to use apk batch installer from chip. i will add it to the list ty :)

[Kindle Fire HDX 7" & 8.9" General] cerveca:
Follow the tutorial on page 1, but start with the 13.3.0.5 binary before continuing with 13.3.1.0 (and so on). Basic procedure as described.

Everything worked fine :)

Bought a LTE Variant from Amazon during this 130€ off advertisement, the thing shipped with 3.2.1 Firmware.

Followed the steps in this tutorial to root, disable OTA and install Safestrap ( in Airplane Mode :) )

Then followed the Steps to flash Nexus Rom into a Boot Slot i created, all is working like a charm (except LTE within the Nexus)

Now i got Fire OS and Nexus as an option running on a real high end hardware. I must say that these Fire HDX tablets are really worth their price.

Thanks to all that are contributing and helping especially taette and ggow!:laugh:

So SafeStrap works on Fire OS version 3.2.5. Do I need to rollback on version 3.2.6 or am I fine without it?
[Kindle Fire HDX 7" & 8.9" General] taette:
you are fine without 13.3.2.6 but if you wanna install the custom rom "HDX Nexus ROM v2.0.2" you have to be on 3.2.4 so you have to roll back, but you only need root and safestrap / xposed then you are fine.

Hi,

I wanted to thank for this tutorial, saved me some time how to root! :good:

My device: Kindle Fire HDX 7", Software version was 13.3.2.1 or 13.3.1.2. I don't remember but I followed tutorial step 2a)

I want to share the issues I had, maybe someone faces similiar things:

USB driver didnt' install (correctly?). In the end, I downloaded the Android SDK, added the URL for amazon and downloaded+installed the Kindle USB driver.

URL: http://kindle-sdk.s3.amazonaws.com/addon.xml found on https://developer.amazon.com/sdk/fire/setup.html

I couldn't run KFHDX. It started, the DOS box opened, loaded everything very fast and crashed before showing the menu. There were no problems using the sandbox of the firewall but no connection to the kindle in the end (sandbox...). Finally, some security settings of my firewall seemed to block correct execution of KFHDX. I didn't investigate deeper since I was short in time.

Now, I have HDX Nexus running but I had to give it back to the "management" since it's a xmas present :crying:

see you

Are the firmware posted in this thread compatible with LTE versions also? I have HDX 7 64g LTE. I've already rooted it, but I can't seem to get safestrap to work (my version is 13.3.2.1). Someone with the same device told me she upgraded to 13.3.2.4. in this thread and was able to use safestrap, but she couldn't verify if her LTE still worked because she didn't have a sim card to use on hers. I just don't want to install the firmware if I may lose LTE. I hope someone can answer this.

Great guide and helps a ton trying to maneuver through the forum posts. It was time to wipe my device and upgrade. Mainly to increase the data partition to install Hearthstone along with other apps. Went from 13.3.1.0 and safestrap 3.72, to safestrap 3.75 and the Nexus 2.0.2 rom.

For option 2a, when its time for towel root you have to go back into the more menu to select towelroot. But now I am just nitpicking.

I've a replacement kindle so want to run through this prcocess again, faulty screen

couple of question from me, I installed the OTA blocker but the kindle still seemed to upgrade to 4.5 something after the root was done. What did I do wrong?

I didn't apply the sarestrap 3.75 it was the 3.72 version, how do I transfer the .APK file over?
[Kindle Fire HDX 7" & 8.9" General] travanx:
On mine the OTA didn't take automatically. Did you turn wifi off and go in airplane mode? Going through the steps I don't see how the device can upgrade on its own.

I just connected my device to the PC and put the safestrap.apk into the download folder where I keep all my apks. I was coming from safestrap 3.72 but never turned OTA's off since I got the device about a year ago and never had an issue of the Kindle upgrading on its own. Turn off your router wifi to be extra sure?

As to towelroot I couldn't get it to work on my Galaxy S5 phone the way some others got it to work. I would go back through all the steps again.

[Kindle Fire HDX 7" & 8.9" General] reggie9:
Hi - How could I use TWRP on Thor (HDX 7 13.3.2.1). Trying to get up to speed here. In theory it would be nice to root this kindle (preferred method?), prevent OTA updates, backup stock image, create new slots, and install some new image(CM11??) into new slot and activate that slot. That way I could use this as I want and when I need to activate the stock image slot. That sounds ideal to me. Am I making sense here? Thanks for your comment.

Still trying to get a feel for when to think TWRP and when to think Safestrap

EDIT: 2015/01/30 - More Reading - How to proceed with KFHDX 7 13.3.2.1 installed:

My thoughts now are to :

1> Root tablet with Towelroot

2> Install Superuser

3> Disable OTA Updates

4> Install Safestrap

5> Create 1 or more new Slots for images

.???

8> Install CM11 and be able to boot into that and have more or less a stock Android tablet

[Kindle Fire HDX 7" & 8.9" General] jeryll:
FW version = your (Fire)OS version

Swipe down from the top of the screen to open Quick Settings, and then tap Settings.

Tap Device, and then tap System Updates. You should see something like this: Your device is running Fire OS 4.x.x

and yes, it is rootable, continue here:

Root for 4.5.2

If your device automaticaly upgraded to xx.4.5.3, you can continue here:

[Rollback][Downgrade][Thor (HDX 7)] [Apollo (HDX 8.9)]

But before you do any changes to your device, know that kindle is not your average android device, one mistake, one wrong step can be fatal/deadly, this device lacks most of recoverable options, other devices have, on rooted xx.4.5.2 you have practically NO safety net (no custom recovery, no unlocked bootloader) ... so before you really do something you regret later, read, read, read, and if you do not understand something, ask...

Does anyone have a guide that takes the original steps from OP and goes to CM12 with unlocked bootloader in Windows? I am on safestrap/nexus rom and don't know where to begin.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Nope. Signature suggests you are on 3.2.4 from which there is a path to CM12:

- uninstall safestrap (you'll loose Nexus; backup as needed)

- roll back to 13.1.x.x (or any firmware at/below 3.2.3.2)

- install native twrp

- unlock your bootloader

- flash CM12

A fair bit of work in those 5 steps with lots of sticking points and a couple brick opportunities. Likely the reason there isn't a tutorial. Details are in the forums but it takes some reading. Note starting point is not the OP in this thread. Safestap isn't part of the CM11/12 config.
[Kindle Fire HDX 7" & 8.9" General] travanx:
:good: That's exactly what I was looking for. I have been reading through the threads this week trying to figure this out, and wasn't sure what order I need to do things in. I guess at this point its cross my fingers since I am going to do this on a Win 8.1 PC.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Footnotes:

- you will be reenabling OTA and potentially WiFi in several steps. As a precaution delete any WiFi profiles before renabling OTA. Airplane mode

may

not stop an OTA (I doubt this is true but some claim that it happened)

- might be easier to upgrade to 13.3.2.5 or 13.3.2.6 and then roll back; avoids having to modify build prop which has been problematic for some

- if you roll back to 13.1.x (or any level below 13.3.2.3.2) you should update your bootloader before unlocking (here). Bootloader only; never update Fire OS past 13.3.2.3.2 after TWRP is installed (it can be done but the technique is the topic of another discussion).

- The best remedy to Win 8.1 drivers is to delete existing drivers and then allow Windows to reinstall when the device is connected in the desired mode (eg: ADB or Fastboot). There are several posts that have links to known good drivers.

- If you run into trouble STOP and post a question. Don't deviate from the prescribed procedure or do despirate things such as a factory reset. Fastest path to a brick IMHO.

Good luck!
[Kindle Fire HDX 7" & 8.9" General] DB126:
Nicely done. I relived some of your pain reading through the various steps! Forgot about x64 driver signing and 3.2.5 being a prerequisite to 3.2.6 (not needed) when updating via modified OTA. Ran into both at some point. A BIG thanks for including links to the various sources you used (happen to be the ones I like too). I believe this is the first post with everything in one place and will likely become a 'go to' resource for others. Finally, yet another tip of the hat to the handful of devs and other talented individuals who created the source material that we all benefit from.

factory reset on rooted HDX7?

Hello guys,

I bought my Kindle Fire HDX 7 in last November and the first thing I have done after I opened the box is put into airplane mode and rooted it. It was working fine but a few apps just started crashing in the last couple of weeks so I deceided to wipe them all from the tablet. Factory Reset would be the easiest way but I do not really know where to start.

So my main question is how to reset my device without bricking it?

It's on 13.3.1.0 with Safetrap 3.72, SuperSU v2.14, Xposed 2.6.1 and might be more softwares that could cause some problems during the progress.

Once my tablet is clear I would like to try out some custom ROM e.g cm11-12 or a Nexus ROM.

I would really appreciate it if some can give me a link which explains me how to do it step-by-step or just help me out with some hint where to start.

Thank you
[Kindle Fire HDX 7" & 8.9" General] DB126:
Don't factory reset - at least not yet. Path forward:

- remove Xposed, Safestrap and any other app that has hooks into the system (basically anything that

requires

root access). Retain Fire OS 13.3.x, root and SuperSu.

- download 3.2.5 here; print upgrade instructions

- disconnect from wifi and remove all wifi profiles

- disable/remove OTA blocker (if installed)

- upgrade to 3.2.5 using previously referenced instructions

- reroot using HDX toolkit (optionally block OTA with the same tool if you plan to enable wifi; must be unblocked for next step)

- downgrade to 13.1.0 (here) following instructions in lower part of post. DO NOT MESS WITH BUILD.PROP!

- install twrp (here). Disregard bootloader unlock and 3.2.3.2 firmware guidance for now

- upgrade boot loader to 3.2.3.2 (here)

- flash Nexus 2.0.5 or CM11 (you can't get to CM12 without additional steps)

This is just a rough outline; you need to do your homework for each step. Read the relevant threads and take note of cautions and gotchas. Be aware there is significant risk associated with some steps that can yield a hard brick. Plan your actions and don't take any step without an understanding of expected and unexpected outcomes. Post questions in the forums if you are unsure.

A more expansive version of the above along with bootloader unlock guidance can be found here. Good luck!

Using 13.4.5.5

Hi all - my HDX is on 13.4.5.5

Does anyone know how I can downgrade to a version that I can follow these instructions for? Thank you!
[Kindle Fire HDX 7" & 8.9" General] DB126:
Instructions in this thread predate FireOS v4, Safestrap v4 and newer roms. Since 4.5.5 can not be directly rooted you need to rollback to 3.2.8, upgrade to 4.5.2, root, block OTA, install Safestrap v4 and then flash one of several roms customized for HDX. The rollback procedure is risky and can easily result in a brick. Start with the following link. Read everything you can find before proceeding. Good luck.

Just wanted to clarify that last bit - Installing CM11 via Safestrap v4 doesn't require an unlocked bootloader; installing it via TWRP does. Does that sound about right?
[Kindle Fire HDX 7" & 8.9" General] DB126:
Correct for the latest build. Note there is at least one early CM11 variant that can be flashed via TWRP on a device with a locked bootloader but there are some reported issues that remain open.
[Kindle Fire HDX 7" & 8.9" General] neverborn:
Thought so, thanks. And any version can be installed safely via safestrap, yes?
[Kindle Fire HDX 7" & 8.9" General] Cl4ncy:
You must use Safestrap v4 compatible ROMs in Safestrap v4 only! Read the ROMs installation notes and requirements carefully.

Regarding CM11 you must use the Safestrap v4 compatible version to install it via Safestrap v4.

CM12 is NOT Safestrap compatible!
[Kindle Fire HDX 7" & 8.9" General] DB126:
No - only roms that specifically indicate they are safestrap compatible. Pay attention to versions and device types. As of this post Nexus v4, CM11 and custom build of FireOS v4 work with safestrap v4. CM12 does not.
[Kindle Fire HDX 7" & 8.9" General] neverborn:
Right, thanks again. Think I'll keep on patiently waiting for fire os 5 for now.

Edit: Couldn't resist. CM11 just makes this infinitely more usable!
[Kindle Fire HDX 7" & 8.9" General] neverborn:
I've set it up so that

Slot 0 - stock rooted 4.5.2

Slot 1 - cm11

Pretty happy with it, but with the safestrap backups etc I only have around 5gb usable space left.

Would it be terribly unsafe to remove the stock rom, in the interest of freeing up space? Sucks that I have the 16gb version but for the price I got it I really ought not to complain.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Not terribly unsafe if you take the proper precautions. Suggest backing up stock (FireOS) and copying to another device for safe keeping. Then backup slot 1 and restore to the stock slot (slot 0). Once you are confident all is well you can delete slot 1.

If needed there are ways to restore FireOS under Safestrap v4 if your backup doesn't work.
