For you think this means we might get 5.0 at some point? Or does this just patch whatever bug kingroot exploited?

My opinion - no lolipop for us.
Just security update (kingroot fix).

No business case for deploying a new branch of FireOS to a discontinued product line (3rd gen HDX).

I agree, and I know that the official word from Amazon is that we won't get it, but I didn't thin we would ever see an update from 4.5.5.1, and here we are.

I just wish they would be out with a new hdx. The new tablets just don't stack up. And I wish that since this is a discontinued device, they would release a n official bootloader unlock.

4.5.5.2 patches vulnerability(s) that permitted device to be rooted. Root is not a good thing when you consider Amazon's business model. Fire devices exist solely to drive additional revenue from Amazon's retail properties (store, video, etc). A rooted device likely won't be used for that. How many people install the Play Store or a custom rom so they can buy more stuff from amazon.com?

I doubt we will see an HDX (high end tablet) equivalent anytime soon. Those devices generally don't attract the demographic that responds to Amazon's marketing machine. Also note the lone HDX survivor (4th gen Saturn) remains tightly locked down. If Amazon does refresh the tablet lineup this year the new offerings will likely be tough to mod.

Is it possible to downgrade From 4.5.5.5.2 Tod 4.5.5.5.q? I miss Google cast

Not without root or a specially formatted downgrade image; neither are available at present.

A risky option is a rollback to 3.2.8 followed by a controlled upgrade to 4.5.2 or 4.5.5.1, both of which are rootable. Once rooted you can block OTA to prevent further unsolicited upgrades from Amazon.

Advise close guidance if you go this route. A small mistake can lead to an unrecoverable brick.

New build of 4.5.5.2 for Apollo

New update - Fire OS 4.5.5.2 "Sangria" based on KitKat 4.4.3 build KTU84M

HDX 7 - https://kindle-fire-updates.s3.amaz...gNf/update-kindle-13.4.5.5_user_455004220.bin
HDX 8.9 - https://kindle-fire-updates.s3.amaz...vGh/update-kindle-14.4.5.5_user_455004220.bin

Build 43 is out for Apollo.

Quite a few files differ, but it's unclear if this depends on some embedded date or version string, as opposed to differences that matter...

 

[ukegste]

4.5.5.3 just landed.

 

[draxie]

OTA only?

4.5.5.3 just landed.

Can you provide a link?
I've just checked and the
official update pages (7,8.9)
still show 4.5.5.2 as the latest.

 

[ukegste]

OTA

Can you provide a link?

Sorry I received it OTA, Silk reports the OS as Android 4.4.3, KFTHWI Build/HTU84M (this means nothing to me).

The update said it included 'general improvements and performance enhancements'.

That's what I suspected...

Could you check the version and date under Settings / Device Options / System Updates?
Mine (which also has the same build ID 'KTU84M ', but 4.5.5.2) shows the following:

Your device is running Fire OS 4.5.5.2 Learn more
Build date Wednesday, July 20, 2016 23:33 GMT+02:00

If you know your way around 'adb', the output of the following commands would be even more helpful:

adb shell getprop ro.build.fingerprint
adb shell getprop ro.build.version.name

Oh.. I could have sworn the Build ID was HTU84M earlier but it is KTU84M (which I believe is the same ID listed on the first post for the release of 4.5.5.2).

How did you get Settings > Device Options > System Updates to list the build date? Mine states 'Your device is running Fire OS 4.5.5.3 Learn More' 'Installed Friday, 13 October 2017 00:49 BST'

I've never used adb but should be able to get to grips with it but I'll have to read up and get back to you.

Hmm...

I didn't. That's what it shows by default on that version.
Perhaps, this difference is one of those 'enhancements'
you got delivered with 4.5.5.3.

I've never used adb but should be able to get to grips with it but I'll have to read up and get back to you.

That would be appreciated.

I scared this is reaction to my post "It's easy to root 4.5.5.2". Now they probably stop the root with Kingroot.

Unlikely

I seriously doubt that. See this post.
I find it more likely that it's a fix for [URL="https://www.krackattacks.com]KRACK[/URL].

Haha...that also means Amazon still support such old device.
I have HD8 2017 now but it's extremely slow compared to my Kindle hdx Thor. Typing this with Thor.
