Thanks Davey126

The link appears to contain all the information I need, but I may have to take it to a third party to have this done. I'm currently on an archaic MacBook that's maxed out at 10.7.5 and I'm not sure my software is compatible with the required installers. I'll have to do some digging.

Thank you very much.

Powering on and off

I unlocked the BL on my kindle HDX 7" using the Multi-platform 1-Click bootloader unlock for 3rd Gen HDX guide. I Flashed the [DISCONTINUED][ROM] [4.4.4] [STABLE] HDX Nexus v4.0.5. I believe I may have missed some vital steps and also that I had Safestrap installed and not the correct TWRP (I thought they were the same). I'm now stuck in boot loop with the kindle fire grey logo. Is there anything I can do to recover my tablet? Please help, thank you.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Yeah - you jumped in front of the train instead of on it. Always review safe boarding procedures before attempting to ride.

Normally I would say your device is permanently bricked. However, if you actually unlocked the bootloader then you *should* be able to install the proper TWRP version from fastboot using instructions here. If successful you can then recover your device and flash a compatible rom using normal means.

To enter fastboot on an unlocked HDX press <power>+<page-down> from a cold start.

ADB and Fastboot Instructions

I appreciate your help, I will try this out. I'm able to get to the fastboot screen on the Kindle but I'm having a bit of trouble getting windows to recognize my device. Do I need the Kindle SDK(Is it still available)? Can you maybe direct me on how to get my device recognized and where I should place the <recovery-image>? I'm a bit rusty with all this as. Thank you.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Start with the forum index with focus on establishing fastboot communication. You'll likely stumble with drivers; always problematic on Windows. Tips:

- open device manager

- put device in fastboot mode

- physically tether; observe changes in device manager

- delete whatever gets auto-installed

- reboot both devices

- repeat procedure directing Windows to use desired drivers

The previously provided link includes the command for installing (flashing) a new recovery. The image itself resides on the host and is transmitted to device when the command is issued.

The above only works with exploitable/unlocked bootloaders.

In my case, i foolishly attempted to flash twrp on 4.5.5 - the device still works perfectly on the os side. but i cannot rollback because i cant boot to recovery. is there any way to flash the original recovery so i can rollback?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] spaceywilly:
I was wondering if anyone could help me out with some power issues. I have an HDX 7" (Thor) running CM-11 flashed to the stock location in safestrap. I have it mounted in my car and I would like it to come on instantly when the car is turned on. What's happening currently is it seems to always shut down, rather than staying in sleep mode, so when I turn the car on it has to go through the whole boot process. I would like it to just stay in sleep mode rather than shutting off completely. When it comes back on the battery usually has quite a bit of charge left so it's not like the battery is dying completely, it just seems to like to shut off after it's been asleep for a while.

Does anyone know how to control this behavior?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Booting into stock recovery is not a prerequisite to downgrading (HDX recovery has no install/rollback option). What are you trying to accomplish?

---------- Post added at 02:22 AM ---------- Previous post was at 02:17 AM ----------

I have not observed this on CM or Nexus (which is my daily driver). As a diagnostic measure try disconnecting the USB cable before putting it to sleep.

[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Nothing can be done if a 'factory reset' does not fix the problem (which it probably won't). The stock HDX recovery does not support options to repair/reload a corrupted system partition or allow remediation via adb or other tether. Factory/factory cables don't work with this device. Only option is board replacement. Sorry for the bad news ...

I can't root my kindle fire hdx 8.9 3rd generation 2013 model no GU045RW serial B018. was on fire os 4.5.5.1 downgraded to 3.2.8 then upgraded to 4.5.5.2 tried to root with kingroot, rootgenius, towelroot and then cve201479xx apk making sure i selected the developer option to allow mock locations. but nothing works on 4.5.5.2 or 4.5.5.1. now on 3.2.8 yes it roots but to my understanding i want to be in the latest for the most compatibility with roms and such so if anyone can tell me what other options are out there. i will appreciate some help
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
- roll back to 3.2.8 (be sure to keep WiFi off)

- tether and block OTA updates using HDX Toolkit

- root with towelroot (you'll need to switch on WiFi briefly for root to complete)

- unlock the bootloader using [MENTION=5828306]draxie[/MENTION]'s "1-click" utility (here)

- install (flash) TWRP and the rom of your choice (both must be compatible with HDX devices)

An unlocked bootloader opens the door to all available roms regardless of the previous version of FireOS installed on the device. Also significantly reduces the risk of a 'hard' brick although soft bricks are still possible (and recoverable).

[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Hi - I did not author the wonderful '1-click' tool; I have copied the developer in for expert guidance. However, it appears you did not respond to the prompt that requested permission to downgrade the bootloader to a version that can be unlocked. If true the unlock attempt almost certainly would fail.

Let's see what [MENTION=5828306]draxie[/MENTION] has to say.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] draxie:
That's exactly right.

Doesn't the transcript speak for itself? :p

I certainly tried my best to make it very clear:

Unless the "user" takes responsibility by typing 'Flash ANYWAY',

1-Click does the rites knowing full well that the unlock won't work.

BTW, it seems from the above that due to some odd timing (I suspect,

the Enter key got stuck somehow) a log message from the kernel got

printed right at the most crucial point, which may be confusing.

Thank you Draxie for the clarification, the 1-Click is amazing, and you are right as the user i did not type what was needed. i feel like such a noob... after clicking the bat file, after all those scrolling scripts, i get the first question and in yellow is the "Hit Enter to Continue" second question, "Hit Enter to Continue" after a few is the "Select Device -1" so i enter 1 then click enter. now the next question says "Enter Flash ANYWAY" noob me read it as hit enter to flash anyway! thats where the user failed to follow instructions... but now im on CM13 and that is amazing its a long way for the $50 craigslist tablet now i can give it to my son. Thanks againg Davey126 for your guide and Draxie for the amazing 1-Click utility. :cool:
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] draxie:
LOL..

I believe, but I'll doublecheck later, that the 'Flash ANYWAY' part is in RED (or, it should be).

In any case, given the success rate (I still haven't heard about any bricks), I might just make

this less scary and even more obvious in the upcoming version.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] zerawkid:
Alright, friendly community. Here's what I have (not a bricked device!):

Thor with Safestrap 4.01 (TWRP 2.7.1.0)

ROM Slot: stock

I am running HDX Nexus ROM 4.0.5 [MENTION=5749760]ggow[/MENTION]

Kernel: 3.4.0-perf-gbfccc1e build@ip-10-11-3-207 #1

Here's my deal, my HDX has been sitting in a drawer for awhile. I want to get it updated a bit, as it stands, the version of Gapps is such that the Play Store closes immediately upon trying to load it. Do I need to update Safestrap/TWRP at all? What I would like to accomplish is getting a good, stable ROM on this device that is easy to update.

A few months back, I attempted some updates on my previous HDX and bricked it. I am asking for guidance so that I can avoid such an occurrence this time. I'd like suggestions and a little walkthrough. I'm a capable technical mind, but certainly out of practice. My computers are Macs, so there's that consideration.

Thanks so much, folks!
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Choices:

- unlock bootloader to gain access to the full suite of custom ROMs available for this device

- refresh stock kernel (involves updating FireOS to 4.5.5.1); reinstall Safestrap v4 and the latest build of Nexus which includes the Play Store

While the first option seems more inviting there are a few technical (some may say logistical/operational) complexities that have proven a barrier for some. A tool to streamline the process (1-click) is currently unavailable as it undergoes some enhancements; developer's time is at a premium so there's no ETA. Second option is more approachable but requires some advance reading; probably not something you are going to complete in an evening. Perhaps the best resource is this tread which follows another contributor through a similar path. Good luck!

p.s. In case you are wondering there are no step-by-step guides that I'm failing to expose. You have to do the homework which is time consuming and often confusing. The community is here to help with specific questions but responses may be slow in coming.

Alright, I am at a bit of an impasse. I am having trouble getting my Mac to recognize my HDX. I fire up the HDX, head into the boot loader, connect it to the computer, and can't get it to show up, nor can I get adb to recognize it.

I wonder if there are any steps I can take, any troubleshooting here would be much appreciated.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Sounds like you are trying to unlock the bootloader. Having retired my last Apple gizmo a few years ago I can't be of much assistance with OS-X/macOS connectivity issues. A new version of '1-click' bootloader unlock is in the works which is supposed to be multi-platform. Suggest waiting for that or find a friend with a Windows machine.

In the interim you can still update to FireOS 4.5.5.1, reinstall Safestrap v4 and enjoy the latest builds of Fire Nexus and CM 11. No tether required :)
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] zerawkid:
Sounds great! Here's my issue, my reading and research leads me to believe I need to push a ROM of FireOS 4.5.x over what I have on the device currently so that I can then OTA update to 4.5.5.1. Is there another way to get my device to a state where I can get it up to 4.5.5.1 and then re-root and Safestrapped?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] grackle44:
Am I screwed?

We have a Kindle Fire HDX 7" - 2013. I had previously rooted it, and installed the Nexus mod. This worked fine for about 6 months, but since it was now mostly being used by the kids, wanted to take it back to the stock ROM so we could utilize the Amazon screen time feature. I downloaded what I believe is the correct SafeStrap Thor package, but then I made what I think is a critical error -- I preformed the wipe before I loaded the ZIP onto the Kindle. Now the Kindle will boot only up to SafeStrap, and I can open up SafeStrap (4.01), but I can not get it to mount on my Windows 10 PC, so I can't get the ZIP on to it. I've searched the forums and mostly only found bad news, is there any chance I've missed a solution to this problem?

PS If I just let the Kindle boot, it gets to an Amazon screen that says "No operating system found" and gives me the option of trying again or rebooting the device.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Quick summary (part 1):

- if necessary install ES File Explorer (Play Store or here)

- download Safestrap v4 compatible version of FireOS 4.5.2 (here)

- download stock version of FireOS 4.5.5.1 (here)

- download Safestrap v4 (here) and Fire Nexus (here)

- download latest Kingroot app (here)

- using ES File Explorer create a folder called 'mystuff' under /sdcard and move all of the above downloads to that folder

- from Safestrap recovery verify you have no secondary slots (remove them if you do) and Nexus 4.0.5 is installed in the STOCK slot

- from Safestrap recovery flash FireOS 4.5.2 (be sure to use the correct file!) to the STOCK slot

- reboot system but do NOT register device w/Amazon or enable WiFi

- from Safestrap v4 app (not recovery) uninstall Safestrap v4 recovery (you may have to reinstall Safestrap v4 app)

- using ES File Explorer move FireOS 4.5.5.1 image from 'mystuff' folder to \sdcard (should not be in a folder)

- use instructions at the bottom of this post to reenable OTA updates with ES File Explorer (you may have to reinstall it under FireOS 4.5.2)

- use the native 'check for updates' feature in FireOS to process the 4.5.5.1 update (do not enable WiFi as update file has already been positioned)

- when device reboots do NOT register device w/Amazon or enable WiFi; suggest enabling 'airplane'/'flight' mode as an additional precaution against OTA updates

That's enough for now. Next steps involve rooting w/Kingroot, blocking OTA updates (different procedure), reinstalling Safestrap v4 and flashing Fire Nexus. Post back when ready. I strongly advise reading through cautions in previously linked thread as you are assuming some risk executing the above procedures including the possibility of a non-recoverable brick. Double check everything before executing anything; ask if unsure.

---------- Post added at 02:08 PM ---------- Previous post was at 01:58 PM ----------

If a compatible Safestrap v4 compatible rom zip (there are only three) is not currently on the device it is not recoverable. There is no way to communicate with or transfer data to a locked 3rd gen HDX without a functioning ROM or custom recovery. Safestrap v4 is not a true recovery; it simply emulates one for the purpose of installing custom roms and performing other maintenance tasks. Sorry for your loss.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] zerawkid:
I think that, in the mean time playing around in Safestrap, I might have done something to doom myself. I was tooling around with the ROM slots, created one, and tried to boot from it. I powered the device off during an Amazon restore and got back into Safestrap. Now, whenever I try to boot, I get nothing but boot animation.

I killed it, didn't I?

Maybe I can convince Amazon to send me *one* more.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] grackle44:
Thanks Davey126. That's what I thought from having looked around. No huge loss since we got it for free. Thank you for your help and prompt reply!
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Hence the reason I advised (multiple) to review prior posts for important cautions - including the liabilities of creating secondary slots and messing around with Safestrap functionality that is not applicable to this device. Really serves as an important note to self: stop wasting time servicing this thread with (often) personalized guidance that gets ignored and just point to the huge trove of existing information. Sorry for your loss...entirely preventable.

Amazon typically offers a single courtesy exchange during the warranty period. As new 3rd gen devices have not been sold during the last 12 months (at least in my region) the warranty has likely expired. Reconditioned devices are sold w/o warranty.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] zerawkid:
Hey man, I apologize for wasting your time, I sincerely do. I appreciate your response...and, it is likely I'll get another HDX and work on it in the future. Your perspective and my mistake will likely not be in vain. You're right, entirely preventable...that said, people make mistakes. I thought I had read enough. Clearly, I had not.

Again, I thank you for responding to my initial inquiry and tossing all that information at me.

Tempted to have a go at this..

Just bought the new Kindle HD 8 and now very tempted to have a go at flashing stock android on my 3rd Gen Kindle HDX 16gb (on latest software version) it seems rolling back to 13.3.2.8 is my first job as I have never tried to alter the original configuration in any way shape or form before, but I have flashed other android devices before. I know its easy to brick but sounds worth the risk what are the drawbacks? does all the hardware, bluetooth etc work ok. Im happy with whatever is the most stable rom that supports chromecast and only install things like kodi, mx player and Plex so as long as they work I would be pleased.

thanks Guys
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
What version of FireOS is currently loaded? If 4.5.5.1 or lower no need to roll back. Disable WiFi (or engage airplane/flight mode) immediately to avoid an unwanted OTA update.

HDX is superior to HD8 in almost every respect except for storage as it lacks a SD card slot and does NOT support OTG. If your music/video library is extensive the limited onboard storage will quickly become a burden. HD8 is not a bad device at the price point but no root or custom ROMs yet. The 7" 5th gen Fire is a better value with several mainstream roms and a large community of active supporters.

Brick risk is low (manageable) if guidance is followed. Those with bad outcomes generally suffer self inflicted wounds. That said - time, skill and patience is required. Not the most friendly device to work with and unforgiving if one deviates off the beaten trail.

Hardware support is generally ok with exception to bluetooth and LTE radios which can be problematic with some ROMs. Chromecast is hit and miss largely due to Google imposed restrictions. Your gonna have to go with mainstream apps like Chrome and YouTube.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] sinbad1971:
Im pretty sure it will be on the latest 4.5.5.2 as I haven't tried to block it updating in anyway and its used daily, understand its risky to do rollback to 3.2.8 with that firmware, So its 50/50 whether it will brick it? I would be using Windows 10 for flashing it.. what makes the rollback risky??.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
A USB tether is not required (albeit sometimes helpful) so host platform is irrelevant. Primary brick risk comes from allowing device network access during rollback which immediately downloads an incompatible OTA update from Amazon. Solution: keep WiFi off until rollback and subsequent updates are complete. Secondary risks are varied but generally result from "knowledgeable" individuals wandering off script believing there is a more expeditious path. Err, no. Also the inherent risks associated with any flash/update operation that involves the system partition. Negligible but not zero. Stock devices brick everyday processing routine updates. Especially locked HDXs which offer no mechanism for reloading the system partition if it gets borked. A significant oversight by Amazon that was subsequently addressed in 5th+ gen devices.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] sinbad1971:
Ok I will just turn my wireless router off while doing the rollback or tell FIRE OS to forget my router password. So if you could point me to a suitable guide for the initial steps I would really appreciate it.
