I don't get an option to wipe just the cache. It's only reboot or reset to factory.

It will show the charging screen (the battery symbol) if the battery has completely died and it's plugged in. If it has a charge and I plug it in, it will automatically start to boot. The screen while show the Kindle Fire logo and have a message "Installing System Update" and it will eventually change to "Error" and then reboot. That is when it goes to the factory reset that I mentioned in my first post.

How can I clear the cache?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] sd_shadow:
Yes, unfortunately amazon has disabled stock recovery options that could have fixed it, like adb sideload update, and even wipe cache.

the bootloader is locked, so really can't do anything with that.

I'm not seeing any that even can be tried.

Depending on how you use the Fire, the new 2015 model may suit your needs, and is only $50.

I have been carefully reading and taking notes on how to root my kindle fire hdx 7" (Thor) (4.5.5), starting with these two threads:

http://xdaforums.com/kindle-fire-hdx/general/index-kindle-fire-hdx-7-8-9-t3206703

and

http://xdaforums.com/kindle-fire-hdx/help/help-fire-os-4-5-5-to-custom-rom-t3196884

In the second link I've read up to the "root with Kingroot". When I click on that it takes me to the kingroot page and it shows that the newest version of kingroot is 11/13/15, just 2 days ago.

Any chance this version works with amazon system 4.5.5 and I don't have to go through the rollback and upgrade steps?

If I still have to do the rollback and upgrade (I'm assuming I do), does it matter which version of kingroot I use? Should I use the most current (4.6) or go back to 4.5.2 or even 4.5?

Also, since I'm asking one question, I want to make sure I understand the steps I've read so far:

before I do anything I should turn off wifi and enable airplane mode on my device correct?

Then roll back and update? After update, then I root (which I understand requires a minimal connection to wifi, but still leave airplane mode enabled, correct?)

then disable OTA updates.

Possiblly try it and report back

you need to disable wifi so the device doesn't install an update during the downgrade/rooting process. If it installs an update, best case you will be back to 4.5.5 or worse the device will get bricked.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] anonymous93:
THanks for the answer to my second question. As for the first, if I try it what's the worst that could happen? In other words, what're the chances that I brick my kindle?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] sd_shadow:
if it installs an update, depends where you are in the rooting process,

so put it in airplane mode.

if you mean kingroot, it's safe to try, very little chance of brick.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] anonymous93:
I did mean kingroot. I'll give that a try and report back.

Hard Brick from downgrading to 14.3.2.8

I just want to start off by saying that I don't know too much about rooting or much of Android/Amazon OS in general. I have had my (Apollo) Fire HDX 8.9" since March 2, 2013. I have side-loaded apps and I am just a typical user. I know how to modify applications and such, so I know a bit but probably not as much as I should. I'm up-to-date with a lot of tech, but not all the rooting stuff. Anyway... Last night (November 25, 2015) I decided that I wanted to root. I started by finding some important info, specifically from this forum. (http://xdaforums.com/kindle-fire-hdx/general/rollback-13-3-2-8-rollback-ota-captured-t3046204) So being as lazy as I am I did as much as I could without my computer and got 14.3.2.8 up and running over night. When I woke up I started the setup and enabled the wifi just quick enough to get ES File Manager. I got it installed successfully with no problems and turned off the wifi. After that I didn't really understand the OTA thing and TBH I still don't. I am assuming that is what updates my Kindle automatically. Anyway I just ignored that and moved on to my next step, installing 14.4.5.2. (Which I did on my computer.) After realizing my internet was really slow I decided to go reset the modem. Doing this messed up the modem and it kept going into "Limited mode". I had an idea that it could just be my Ethernet cable so to check that I turned my Kindle's wifi to see if I could connect through wireless. It still didn't work so I just decided to get ready for the day. This was around 11 AM (MST)(Thanksgiving 2015). When I am all done getting ready I go check my computer to see if my wifi is working, and it was finally working. So I go grab my Kindle, but now it wont turn on at all. I am assuming that this is a hard brick. I am still on 14.3.2.8 (I'm guessing that there is still stuff on my Kindle) and have no root and never did turn on developer options. When I connect it to my computer it takes a second and then say that it is unrecognizable. I am aware of "Restore2Stock", but I want to know if there are any other options. I don't want to spend $20 on a service that I don't necessarily trust. Anyone able to help???

If it's on 3.2.3.2 or below, you may very well be able to reroot and install TWRP given that you still have ADB access (which typically isn't the case).

I just bought a secondhand HDX 7. It have Safestrap 4.01 (TWRP v2.7.1.0); Fire OS 4.5.2 in Rom Slot: Stock and CM11 in Rom Slot 1.

I'm a noob to Apollo, what are my options?

I was given an Apollo (KFAPWA with 3G) that is box-stock and unfortunately has the latest Amazon firmware on it, namely 3.4.0-perf-g7abdbab (14.4.5.5_user_455001820). What are my options?

Here's what I would like, but it seems impossible to get there, given what I have already read across the HDX fora:

unlocked bootloader

root

TWRP recovery

a reasonable Android version that would support both Bluetooth and the WAN radio, though I could probably live without WAN

I'm no stranger to reflashing devices (have a Note III and a B&N Nook HD+, both running variants of CM12), and I even have sideloaded apps on the Amazon TV stick, so I have minimal ADB, fastboot and Amazon USB drivers installed. The Apollo has the performance for sure, yet it seems like a different beast, given its locked bootloader and it apparent brickability.

Any advice would be welcome.

Do you know when will the fire os 5 be updated for hdx 7?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] EncryptedCurse:
In order to unlock the bootloader or flash TWRP, your need to be on 3.2.3.2 or below. Given that you're already running one of the newer updates, you can't rollback past 3.2.8, or else you'll permanently brick your device trying. So, these two options are out of reach. The next best thing is Safestrap, although it is not a true recovery, and you're limited to ROMs that are based on the same Android version as FireOS (i.e. FireOS 4 is based on Kit Kat, so you can only use Kit Kat ROMs).

Here's what I would do:

downgrade to 14.3.2.8

upgrade to 4.5.2

root

install Safestrap 4

Again, thanks for the advice and information. The above steps are exactly what I did, along with backup of FireOS and an installation of Nexus 4.4.4 in the "stock" slot (so WiFi would work).

Going from Fire OS 4.5.5 to Custom ROM (CM11 or Nexusv4)

Ok so I have read a BUNCH on these forums these past 2 days. I have read through the threads I think that applies to what I need to do. I have compiled an outline of the steps that need to be taken, written in my own words so I can understand it better. It contains the steps needed to take and precautions that need to be taken. It also contains some questions within the outline if they could be answered please. Also if there is anything I missed, it would be greatly appreciated

•	Enable ADB debugging

o	tap serial number a few times

o	developer options

o	check to on

•	Rollback to Fire OS 3.2.8 (computer to kindle)

o	After installing disable OTA w/ hdx toolkit (or can I yet?)

o	Back up data

o	Keep on airplane mode or turn wifi router off

o	What to do:

•	Connect to computer w/ usb cable

•	Put rollback file into the internal storage folder of kindle

•	Settings → Device →System updates

•	Click update

•	Try with wifi off if it does not show up

What to do after this??? Reboot? Anything?

•	Upgrade to Fire OS 4.5.2 (computer to kindle)

o	Same process as above, but with the 4.5.2 file instead of 3.2.8 file

o	Not sure if correct?

•	Root with Kingroot (tablet)

o	Install the app and run

o	May need internet connection, but make sure to turn off after internet connection is no longer needed

•	Block OTA w/ HDX Toolkit v 0.95 (computer)

o	run the program with kindle connected

o	follow directions on the program and press the correct numbers

•	Install Safestrap v4 (videos) (computer)

o	***

o	install the app

o	install recovery

o	reboot to recovery

o	backup stock → boot options → rom slots

o	restore to get backup into a slot

•	Flash a Safestrap v4 compatible rom (CM11 or Nexus v4) (tablet)

o	***

o	click slot and activate

o	What partition sizes to set?

o	Click install and find folder where the rom file is (should be previously transferred from computer to the tablet)

o	Put in stock slot

o	Save copy of original fire O.S to computer

o	click and swipe to flash

o	reboot to show custom rom (Nexus v4 or cm11)

Do not factory reset at any time

***Wouldn't let me post youtube links I watched on installing safestrap and custom rom, but they were the android cowboy ones.

Which ROM is preferred? Is it easy to change if I don't like one or the other? Thanks for all the helpful posts. I am relatively new to this stuff but I have learned a lot about how all this stuff works.

One last question: Are there any extra programs or anything that I need to download on the computer to send stuff to my kindle? or can I just hook up the usb cable and run everything through it? I just wanna make sure I have the correct stuff so I do not brick.

Going from rooted 13.3.2.2 to unlocked bootloader and custom rom

Hi everyone, I have a couple of questions I hope someone can help me out with.

I am getting quite tired with FireOS, so my goals are installing recovery, unlocking bootloader and getting a custom rom. I saw Cl4ncy post in the first page of this thread and I'm trying to follow that.

However, all the guides I see is from 13.2.3.2. I currently have 13.3.2.2 rooted with towel root; and SuperSU 2.46, busybox 1.20.2-cm9 and abd shell installed, and OTA disabled.

What would be my next step to get twrp, update and then unlocking the bootloader?

Do I have to down/up-grade to 13.2.3.2 or another version to follow this guide (http://xdaforums.com/kindle-fire-hdx/development/recovery-twrp-recovery-2-8-1-0-apollo-t2991155) and how can I unlock the bootloader before getting the recovery (?, as it says in the top note,) or can I somehow skip the step and install recovery right away since I already got root?

And then update the bootloader to 3.2.32 before unlocking it?

Thanks in advance for any replies :)

I think you are ok. Posters sometimes get sloppy with version numbers which can lead to confusion when viewed by another party that wasn't part of the original conversation.

FireOS version identifiers use the following format (at least for HDX): dd.v.x.y.z, where:

dd = two digit device type (13 = thor/7"; 14 = apollo/saturn/8.9")

v = 1 digit major version number (3 = FireOS v3; 4 = FireOS v4, etc.)

x.y.z = subversion identifier. X is the most important value; the rest have little meaning outside the development arena

It appears your FireOS version is 13.3.2.2.0 which is < 13.3.2.3.2. No rollback is needed. You can flash twrp, the 13.3.2.3.2 bootloader update and then proceed with unlocking the bootloader. See the link posted by [MENTION=4267571]sd_shadow[/MENTION] for additional info. You can find a brief outline here (starting with step #5) along with links and suggestions.

Ebay Fire HDX 8.9"

Hi All,

I just took a gamble on a boxed Fire HDX 8.9" from ebay at a good price.

I figured it was a 2013 model given the price, I was just waiting to see what firmware was on there.

It turns out it is on: 14.3.0.5

I immediately turned off wifi and popped it on airplane mode.

This looks really promising for getting CM12 successfully onto it as I'd hoped.

Now I just don't want to brick the damn thing as I feel I'm lucky to have an out of the box Fire 8.9" that's ROMable.

I've read a bunch of forums and believe that I need to do the following:

1) Root and stop OTA with HDX toolkit

2) upgrade firmware to 3.2.3.2 with TWRP

3) unlock the bootloader as per instructions.

4) Flash TWRP custom recovery using adb shell, su and dd to write the image.

Is this the correct ordering ?

I have two questions:

For step 2 there aren't really instructions in sd_shadow's sticky post.

I can't find a post that explains how to do this, anyone got any advice ?

On other fires there was usually a twrp recovery image that I used in flashfire to get to TWRP.

Also, will the update to 3.2.3.2 allow OTA updates again ?

Thanks,

A

Nice find. You have the basic steps identified; very little work is required to prepare your device for custom rom (suggest CM-13 as development has stopped on CM-12.1 although it remains quite stable).

Suggested procedure:

- on initial boot do not register device (no point); can skip WiFi setup too although that mandates a tether for all transfers

- root and block OTA with HDX toolkit

- install Minimal ADB and Fastboot on a suitable Windows host

- sideload ES File Explorer and Flashify; install both via 'adb install <app>.apk'

- (optional) launch Flashify and backup existing recovery

- use Flashify to install TWRP for HDX

- boot to recovery (twrp) to validate installation

- (optional) backup existing rom (FireOS) from with TWRP; transfer backup folder to host if desired

- reboot system and use Flashify to apply 3.2.3.2 bootloader upgrade (important: verify md5 with ES File Explorer before flashing; a corrupt update file will brick device)

- research and attempt to use 1-click bootloader unlock to perform the booloader unlock; a manual method is available if 1-click is unsuccessful (see post #67 to get started; you'll also need drivers)

- and finally (queue trumpet roll) ... flash the rom of your choice from available HDX builds (Nexus v4, CM11, CM12.1, SlimLP, CM-13); FireOS v4 is also an option...sans OTA and other crusties.

Seems like a lot but many steps go quickly. As will all work of this nature have a clear understanding of what you are trying to accomplish in each step and double/triple check everything before committing. As questions as you go along if needed; guessing is a bad idea on this device.

Good luck.

Ebay Fire HDX 8.9"

Thanks again for the advice.

The cm12 upgrade worked well and the tablet is performing excellently.

The only issue I had was that the Google Play Store was giving me Error: 963 and unable to download some apps

This was with the latest opengapps both stock and mini.

I reflashed CM12 with an opengapps from early January and that seemed to fix the problem.

That one had an issue with downloading Google Play Games, but it was easy to get an APK for that elsewhere.

Looks like everything is working flawlessly, just have the little screen glitch that was mentioned when I lock the screen, but that's nothing to worry about.

Looking forward to trying CM13 on this in the future, but for now I'm just happy to have a fully working CM12.

I guess I need to post this question here. Here is what I've got, Kindle fire HDX 8.9. Did the roll back to 13. whatever and then manually installed 4.5.2. Next I used the root method, and now I have full root with access using ES file explorer. I went in and renamed the file that was supposed to block OTA updates. For whatever reason that didn't work, because when I came off airplane mode and connected to my Wifi, the kindle started downloading 4.5.4. I powered it down, went in and re-enabled airplane mode, and did a search for block OTA updates. I found the process that worked. So now No more updates, However I have a 100% status bar with the 4.5.4 waiting to install.

I need to know, where to go in the file system using ES file explorer to deleted the update file and date, so it does not install itself, and the way to clear the status bar showing the update. I need the Devs or other experienced users that can be very specific about what file, and where it is, and what to remove. I don't need to jack up my Kindle fire HDX.

Hello,

trying to get safestrap installed on my HDX 7 in order to use NEXUS ROM.

At the moment I have Fire OS 13.3.2.8 installed and the HDX is blocked for OTA with HDX Toolkit.

I downloaded update-kindle-13.4.5.2_user_452004220.bin and puted the .bin file to the root of the SDCard folder.

Is that correct folder or do have to copy the .bin file to devices root folder "/"?

I already rebooted and tried to look for up updates under systemupdates but the device did not recognize the update-xxx.bin file.

How can I initiate the manual update for the device?
