Another not quite topic-related problem:

The system partition of the kindle is too small to install GApps: there are only ca 30mb free space... Not enough:crying:
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
you can delete /system/tss for example

f#ck I hoped to the last that it will work at 4.5.3 (
[Kindle Fire HDX 7" & 8.9" General] Potato_of_Doom:
Thx, would also be possible but i found an alternative solution (Install GMS normally)
[Kindle Fire HDX 7" & 8.9" General] Phate123:
Good work. Nicely done.

Sadly I'm not able to use it myself. I came home today and saw that the hdx was updated to 4.5.3 in the week I was not at home. :crying: I'm not sure how this could happen. It was switched off and the update servers had been blocked on my router. Have they changed the IP's?

I still want my hdx rooted, so I will have a look on 4.5..3 now. I'm sure there is a way.
[Kindle Fire HDX 7" & 8.9" General] EncryptedCurse:
Has anyone tested Safestrap yet?

As mentioned previously, just contact Amazon for a downgrade (to x.3.2.8) and then manually update to 4.5.2.
[Kindle Fire HDX 7" & 8.9" General] veaceslav:
I used to blame Samsung for how slow they were with pushing updates, and now I absolutely hate Amazon, for how fast they work...
[Kindle Fire HDX 7" & 8.9" General] DisgruntledUser:
Well before I try to flash the unlock.img as mentioned around page 5 on this thread I want to make sure that the fact that my bootloader was upgraded to the 13.4.5.2 and then the os was downgraded so I retained 13.4.5.2 bootloader will not bootloop me if I attempt to flash the img with the new command in order to unlock the bootloader.

Additional if this does work will I need to compile TWRP myself or can I just use the TWRP on the forum here.
[Kindle Fire HDX 7" & 8.9" General] Raptor270:
You say I should'nt upgrade from 4.5.1 to 4.5.2, but would I have any disadvantages?

I thought new firmware is supposed to be better ;)
[Kindle Fire HDX 7" & 8.9" General] EncryptedCurse:

I started from the POC code on github and redesiged it taking into account the patches that were applied to the kernel.
[Kindle Fire HDX 7" & 8.9" General] djclark25:
As this exploit works on 4.5.2 but not 4.5.3 do you think if I contacted Amazon and said had issues since the update to 4.5.3 last week they would roll me back to 4.5.2?
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
I think it looks very fishily, maybe usual rollback to 3.2.8 and manually upgrade to 4.5.2 after that?
[Kindle Fire HDX 7" & 8.9" General] awinston:
I actually tried this and they rolled me all the way back to 3.2.8 instead. I was very clear that I wanted the last update, 4.5.2, not anything older but several days later I was suddenly just rolled back to 3.2.8. You can certainly try, it can't hurt, but my guess is you will get downgraded to 3.2.8.
[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
Maybe the 4.5.1 bootloader has more vulnerabilities than 4.5.2, that could eventlualy lead to an unlock.

After rooting you should be able to upgrade the entire rom, including the boot.img without upgrading the bootloader, but it might be risky and I am not sure anyone has tried it before.

I can make the exploit work on 4.5.1 but I'm not sure it is worth the hassle.

Can someone make a better case then I did against upgrading to 4.5.2?

What do you guys think?

---------- Post added at 11:33 PM ---------- Previous post was at 11:21 PM ----------

Someone with rooted 4.5.2 should request a dowgrade and grab the ota :p. We might have problems if they are able to detect if the device was rooted, but I think it is worth a try.

---------- Post added at 11:43 PM ---------- Previous post was at 11:33 PM ----------

We should first try it on unlocked bootloader devices just to stay on the safe side.

Hello all,

I have hdx 8.9 with 13.3.4.8 and I'm willing to test then apk by manually upgrading to 4.5.2 OS

Can some one let me know what's the worst case scenario, I obviously don't want to brick my device

[Kindle Fire HDX 7" & 8.9" General] djclark25:
Just asked to be rolled back to 4.5.2 through chat. The title was "Apps closing and slow down since update to 4.5.3. i said I had done afactory reset but still had same problem. He didnt even ask what apps or the exact issue I was having, he just said he would send out a replacement!! I asked him 4 times to roll back the software to 4.5.2 but each time he said there was no way he could do it. I told him i thought it was strange that they would rather send me out a brand new one than rollback software but he stuck to his guns.

I decided to say I was going away tonight and wanted the Kindle in a working fashion but he still wouldnt roll back. Was a good excuse as told him I havent got time to sort out returning it and will contact them again after my "trip".....

Will try again later and see if the next person is more helpful. Although I suppose there is the possibility that the replacement might be a refurbished unit on an older firmware (Which mine was but it updated before I knew what I as doing!)
[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
What do you guys think about http://www.cvedetails.com/cve/CVE-2015-1474/?

It might also apply to Android 4.4 (including FireOS 4.5.3), not only 5.0. Maybe we can get system and then root through qseecom.

People were also discussing it here.

4.5.2 root at last!

Confirmed - I had an essentially brand new 7" HDX (Christmas present) that I had not been able to root until now. 4.5.2 now rooted! :victory::victory::victory:

As stated above, when you run the cve201479xx app, click the "Gimme Root" button more than once if possible, and the device will reboot on it's own. You must reboot again manually in order for this to take effect.

Thanks

Now we need a unlocked Bootloader :D
[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
Apollo and Thor are basically the same when it comes to exploits, do not despair.

Regarding the downgrade, something has just struck me.

If people can downgrade from 4.5.x to 3.x.x => bootloader version (4.5.x) <= bootloader version (3.x.x, downgrade version).

But that means that they ever try to upgrade to a normal 4.5.x rom (maybe excepting the one that they downgraded from) they will brick their devices as the bootloader version would be less than the special downgrade ota version.
[Kindle Fire HDX 7" & 8.9" General] Phate123:
This might be a way. I wanted to create a root method for the newest OS version but Amazon was faster. So I am really interested in creating a method for 4.5.3.

What I understand now in this issue is that we need a service that uses the method described in the CVE. This would be SurfaceFlinger. The problem is still that I am unsure on how to communicate with that service from an application. Maybe we should create a new thread for this?
[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
I think every GraphicsBuffer object goes through the SurfaceFlinger. I agree that we should start a new thread. Will you do it?

I see that [MENTION=4276415]p1gl3t[/MENTION] put together a complete & working exploit for root up to 4.5.2. If I may ask, who were the main contributors? I didn't really need this, as I have been unlocked for a while, but I am very much impressed at how you cam together & stuck with it to accomplish this. Nicely done. I will sort through the thread at some point, but I would like to send a little something to the following contributors.

1. Whoever discovered that this existing vuln was exploitable on the HDX

2. Whoever wrote the exploit for the HDX

3. & of course p1gl3t for putting the exploit together in a mostly working ;-p apk (Just a razz about the confusion needing to manually boot caused)

Just so you know, I am cheap, so I won't be making anyone rich :D , but I think a nice dinner or some such is certainly well deserved.

Y'all truly make me wish I still had time to more closely follow security, exploits & development. Sadly, my career keeps getting in the way & after 23 years it's a bit late in the game to move from mechanical engineering to development...

At the moment no, you cant get back easily to 4.5.2. I have phoned amazon multiple times but they wouldnt roll me back. But they would send me out a new Kindle to reoplace my "faulty" one I wanted rolling back. thats coming today and should be on 4.5.2 or before

What I did

Did a factory reset to Kindle Fire HDX 7 with 4.5.2, since 4.5.3 upgrade was partly downloaded before disabled Wifi.

adb install cve20147911.apk

ran cve201479xx, clicked Gimmie Root multiple, device rebooted

manually rebooted (!)

superSU runs now without error of missing su file

adb install myESfileexplorer.apk

enabled "root explorer" (superSU asked for permission)

BUT cannot rename otacerts.zip in /system/etc/security

[Kindle Fire HDX 7" & 8.9" General] Wolverine777:
Assuming you have ADB turned on in the settings, install drivers for Windows. You should be able to get your device to show up like a USB stick would.

Extract the zip, copy to your device (i drop in the Download folder as a working area).

Then install ES3 File Explorer from Amazon (if you haven't already got it).

Launch ES3, go to the Download folder, and launch your extracted app. This should install it. You then just need to go to your Apps menu and run the CVExxx app.
[Kindle Fire HDX 7" & 8.9" General] Applestar:

[Kindle Fire HDX 7" & 8.9" General] DB126:
In most cases yes but with varying amounts of effort depending on the version of Fire OS currently on your HDX. Look around the fourms; all the info is there. In most cases you won't find a tiddy tutorial due to the number of variables involved and recent discoveries. Ask questions along the way.

Sorry, only root for 4.5.2 + gapps for now. This could change in future, but for now thats it. If you really need custom rom downgrade to 3.2.8 (if you have HDX 7" codename Thor, not possible for HDX 8.9") install latest safestrap recovery and then install Nexus 1.0.1 for safestrap. Unlocking bootloader is possible only on 3.1.0 - 3.2.3.2 and you cant downgrade from 4.5.2 (3.2.8) there.

Hey I was wondering how do you exactly root a kindle fire hdx 8.9,is a computer necessary to do it? And is it possible to do it without registering your device?
[Kindle Fire HDX 7" & 8.9" General] DB126:
You'll need to provide more information on your device for a response. Different possibilities depending on the current firmware level and device generation. Details in the forums; a little reading will take you a long way.
[Kindle Fire HDX 7" & 8.9" General] rootnewb386:
Ok I'll look around on here and my device is a a kindle fire hd 8.9 16 gig. And the system version is 8.5.1.all I honestly want to do is flash an android Rom on to it so I can have Google play.I've used odin for my note 3.I'm goin look around on here and odin and see what I can find out.
[Kindle Fire HDX 7" & 8.9" General] DB126:
I am guessing 8.5.1 is a typo; you are probably running 4.5.1. Next question is when the device was purchased. If it is a gen 2 8.9" (with faster 2.5GHz processor; released in 2014) then you can't install any alternative ROMs. If it is a first generation device (2.2GHz processor; released in 2013) then you can downgrade and install a Nexus clone which is based on JellyBean (4.2). There is no option for KitKat or Lollipop at this time.

You can root 4.5.1 and then install Google Play which offers a hybrid Amazon/Google experience. However, it is not a straight forward process and problems of varying severity have been reported included some that effectively disable the device. You should carefully consider the pros/cons before going this route.

In many cases it simpler and safer to root and install an alternative market like 1Mobile which provides functionality similar to Google Play including access to some paid/premium apps. However, you existing purchases will not transfer over.
[Kindle Fire HDX 7" & 8.9" General] rootnewb386:
I believe it is the 2013 model the serial is b0c9 and I truly don't know the system version it's running.when I go to about device under settings it says 8.5.1_user_5156520. Think it says that because it's unregistered? But based off what your saying I think I'm just going to go with the 1mobile I really don't want my device to have severe problems.but before I try and figure that out how do you come across those problems of installing Google play,installing it wrong ?,or is it just a risk you have to take?

[Kindle Fire HDX 7" & 8.9" General] lekofraggle:
Those were my suggestions which were intended to solve the problem. Check to make sure other apps are allowed, and try over and over again. By the fourth time, it should take. This is an oddity though
[Kindle Fire HDX 7" & 8.9" General] gbohm:
you mean i should try to root 4 times or reboot 4 times? I tried both same result superuser apk is in system/app but it is not working.
[Kindle Fire HDX 7" & 8.9" General] DB126:
ok, I'm not a regular visitor to this thread (running Nexus and CM11) but question "superuser apk". Are you referring to the SuperSu installer? If so it is unnecessary to obtain root although obviously desirable after. If you can't obtain root via cve20147911.apk (and there is no further guidance by more experienced users) then I suggest that you rollback to 3.2.8, upgrade to 4.5.2 and then try again. See here for additional links. There have been reports that 2-3 reboots are required before root permissions are granted. Seems weird but easy enough to try. I realize you have been through that already...emphasizing for the redo should you go that route.

Purpose of the rollback/upgrade exercise is to clear out any issues on your device that may be preventing the exploit from taking hold. Annoying as it doesn't offer an explanation but sometimes starting over is the easiest path. Good luck.
