Kindle Fire HDX Apollo 4.5.5 - can't find update

Hi

Please help. I have read this thread for hours, but unable to downgrade my Kindle Fire HDX 7 (Apollo 4.5.5) to 3.x. This is the process I followed;

1. First I Factory reset the tablet, including deleting all user data

2. Downloaded, mod-update-kindle-thor-13.3.2.8_user_713328020.bin to kindle fire using Silk Browser

3. Downloaded the apk for ES File Explorer and installed ES File Explorer

4. Used ESFileExplorer to move the mode file (step 2) to the root of internal sdcard (path /sdcard/)

5. Removed the wifi profile and then added and connected to another wifi router that did not had a WAN connection (needed this otherwise check update does not go further)

6. Enabled aeroplane mode and ensured that the wifi was enabled and connected as well (need this otherwise check update complains)

7. Enabled ADB Debugging (by typing on the serial number 7 times)

8. Now went to settings->device option->system updates->updates and pressed "check now" button

It always comes back with "No updates found"

I have factory reset and used the process several time but with no luck.

In System Updates, Kindle says it is running Fire OS 4.5.5 (build date Monday, 17th August 2015, 22:03 BST)

Please help ...
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
you need mod-update-apollo
[Kindle Fire HDX 7" & 8.9" General] pxjain:
Thanks for your resposne

Just to be absolutely clear

I have bought Kindle Fire HDX 7 inch (3rd Generation) in November 2014. I used the app CPU-Z to figure out that the processor is Snapdragon 800 (2.15 GHz). Reading the forum I concluded that mine is Apollo and therefore I need the Apollo, But in the first page of this thread has following links

So you mean I need to download "Download for HDX 8.9 3rd gen (Apollo)" and not "Download for HDX 7 (Thor)" even though I have a 7 inch HDX.

Thanks in advance
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
hm, no..

If you device is 7-inch - this is thor 100% . And your problem with update still mysterious.

But in your case you been connected to wifi. try to:

Turn off wifi

reboot device

put update

reboot device

check if update appear (do not press check button, kindle must find update and button "update" must appear)

keep wifi off during this procedure.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Thoughts:

- follow [MENTION=5594063]ONYXis[/MENTION] guidance here

- reread this post taking note of small details - especially regarding radio status (do not need to be disabled) and wait times

- verify name, location and md5 of upgrade bin using ES File Explorer

- (unproven) if all else fails grab the appropriate 4.5.5 package here. Position it like the 3.2.8 rollback (which should be renamed) and restart your device. If device finds/processes package (doubt it will as matches current version) it

may

rectify problem/files/config blocking rollback. This is an unproven, extreme longshot that carries some risk if the 4.5.5 update is not processed correctly...same risk as any other rollback/upgrade.

Unable to downgrade

Hi, I have followed your instructions, but when i push file to internal and hit update it says it's unable to because it's an older version than what I have (4.5.5.). any tips? Thanks!
[Kindle Fire HDX 7" & 8.9" General] DB126:
Please verify:

- the .bin placed in internal storage was obtained from post #1 in this thread -and- is the correct version for your device

- you have a 3rd (not 4th) gen 7 or 8.9 inch HDX

- specifically, your device is not a HD or 4th gen Saturn (8.9" HDX)

The error you reported is systematic of having an incompatible .bin or device type.
[Kindle Fire HDX 7" & 8.9" General] Droided715:
Ahh, I do have 2014 (4th Gen) 7". Have tried file in step 1 and another of the same but has "thor" in file name as well. Is this only for 3rd gen? I have tried the factory update w/wifi as well to upgrade, then downgrade b/c I know 4.5.5 is a pain. If this is only for 3rd gen, has anybody been able to downgrade on 4th gen running 4.5.5? Thanks again for your reply. Also, i've copied/paste as well as pushed with adb and as soon as i hit update and it gives that msg, the device deletes it instantly.

---------- Post added at 04:33 PM ---------- Previous post was at 04:30 PM ----------

And it tells me there is no update available even after factory reset and a regular update attempt.
[Kindle Fire HDX 7" & 8.9" General] EncryptedCurse:
There is no 4th generation/2014 HDX 7.

Are you talking about the 2015 HD 7?
[Kindle Fire HDX 7" & 8.9" General] DB126:
There is no rollback option for 4th gen devices. Long story short: 4th gen devices were never provisioned with FireOS v3 so no 'rollback' OTA exists. While it is likely FireOS v3 would run on a 4th gen device no one has attempted to tweak the gen 3 OTA. Part of the reason is any mistake could yield a permanent brick. As all 4th gen devices are pricey 8.9" models I don't think you're going to find many willing to experiment.

Sorry for the bad news ...
[Kindle Fire HDX 7" & 8.9" General] Droided715:
Under device model it says Fire HD 7 (4th Generation). So it sounds like im outta luck? Im a noob to these amazon devices. I was hoping to put a CM rom on it like I've done many times before with other devices. Tried the usual kingroot and such as well. Guess i'm stuck with what the "genius's" at amazon threw on there. :(. I purchased in Canada but believe OS's would be the same. Thanks for your help anyway!
[Kindle Fire HDX 7" & 8.9" General] DB126:
Don't know about HD (this is HDX forum). Look here. As you are discovering Amazon devices do not mod easily. Great hardware, ok OS (for some), lousy customization ability.

Nope. Look here: xdaforums.com/kindle-fire-hd
[Kindle Fire HDX 7" & 8.9" General] Lukebluetiger:
That's just how 4th gen models work, because they have different system apps like firefly, if you really wish to root look up Imma Wake on YouTube and watch his tutorial for 4th gen
[Kindle Fire HDX 7" & 8.9" General] DB126:
Clairification - the above refers to selected HD models. As of this writing no root technique is publicly available for 4th gen HDX devices running 4.5.4 and above. At least to my knowledge :)
[Kindle Fire HDX 7" & 8.9" General] vokuhila:
First of all, thanks for your detailed description.

I followed every step until number 8.

After tapping two times the "Gimmie Root" button in the "cve201479xx" app, the device booted automatically. The boot (and update) process was very fast. It took only approx. 10 seconds. The "SuperSU" app was installed.

After opening the now installed "Safestrap" app, it shows the state "Not Rooted".

During the whole process airplane mode was enabled and WLAN was deactivated. And my Fire device WLAN connection was blocked from my router additionaly.

(Installed the necessary APKs via 'adb install')

I'm sure that i don't make one thing different as described. The results after each step were exactly as described.

Has someone faced the same problem?

Or any suggestions how to continue?

Thanks in advance.

My device is the same like yours:

- Kindle Fire HDX 7, 3rd Gen. (Thor)

- Original OS version was 4.5.5.

- Now i'm on 4.5.2 with the mentioned apps but without root.

Found the solution for my problem here:

http://xdaforums.com/showpost.php?p=59157223&postcount=59

It's necessary to boot manually after step 7 ('Gimmie Root').
[Kindle Fire HDX 7" & 8.9" General] DB126:
You may want to try Kingroot ( www.kingroot.net ) which requires a brief (30-60 sec) network connection but tends to be more reliable. The cve exploit works well for some but proves troublesome for others. Just remember to replace the embedded root manager with SuperSU once complete.
[Kindle Fire HDX 7" & 8.9" General] vokuhila:
Thanks for your answer. It works eventually. I posted the solution under my question. Maybe i'll try kingroot in a few days.
[Kindle Fire HDX 7" & 8.9" General] DB126:
No need to reroot if you already have access. Kingroot comes with some unwanted baggage (not dangerous) so there's no benefit to messing with it if already rooted. Be sure to block OTA before installing Safestrap v4. Once SS is working make a backup of your current config (FireOS 4.5.2 in the stock slot) before flashing a different rom. Leave the backup on your device for a few days in case something goes wrong. Once stable be sure to keep a smaller rom installation image in the root of sdcard at all times; it can be a lifesaver if you rom goes south and you can only boot into Safestrap. Don't mess with secondary slots; only flash to the stock stock slot which will overwrite the existing contents. Read installation instructions for each rom carefully; don't forget to 'factory reset' from within SS after flashing a new rom.

NEVER

perform a 'factory reset' from the native Kindle recovery menu with Safestrap v4 installed. Fastest way to an unrecoverable brick.

Have fun!

guys i need your help .. I have a 3rd kindle fire , which could go down to the 3.2.8 with this tutotial , the detail is that after reboot into 3.2.8 stop on the wifi and I think she is alone and when acualizo sr install the update no longer lit but not turned on fabor brothers help ..

I want to enjoy my kindle :(
[Kindle Fire HDX 7" & 8.9" General] DB126:
You must put the 4.5.2 image in the same location that you put the 3.2.8 image ("internal storage", root of sdcard). Then reboot your device and wait a few minutes for update to be recognized. Keep airplane/flight mode engaged at all times to avoid an OTA update and guaranteed brick.
[Kindle Fire HDX 7" & 8.9" General] miguel_kaka:
Davey126 brother what happens is that my kindle fire , not light did exactly what you said not to do , I update and did not turn , you think the fastboot wire may put in fastboot mode ?
[Kindle Fire HDX 7" & 8.9" General] DB126:
If you left WiFi on after downgrading to 3.2.8 -and- you received an update from Amazon then there is no way to recover the device. It is permanently 'bricked'.

Fastboot cables do not work on HDX devices. On a locked device fastboot is crippled by Amazon. Kindles are not like other android devices.

The language translation is not perfect; sorry if I misunderstood your question/situation.

[Kindle Fire HDX 7" & 8.9" General] DB126:
Given the question you seemingly have no clue what you are doing. You can not flash native TWRP on your device nor would you want to install Safestrap before upgrading to FireOS 4.5.2.

But that likely does not matter now. Guessing you left WiFi enabled after rolling back to 3.2.8 and received an OTA from Amazon which bricked your device. There is no recovery.
[Kindle Fire HDX 7" & 8.9" General] AnyAndroidOSWins:
Hey thanks for this and merry Christmas.:)

I downgraded from 4.5.5 to 3.2.8, updated to 4.5.2, rooted with kingroot, installed SafeStrap v4.01 and then installed CyanogenMod 11 for Safestrap. I finally can choose my theme and launcher and...

....Make it just how I want it:o
[Kindle Fire HDX 7" & 8.9" General] DB126:
Congrats! As you are running CM11 under Safestrap v4 make sure it is installed in the stock slot as there are several significant performance issues when booted from a secondary slot. For veterans this goes against the recommendation for installing roms in previous versions of Safestrap. Nature of the beast when used on a HDX; read through older posts for background and suggested path for disabling secondary slots if needed.
[Kindle Fire HDX 7" & 8.9" General] AnyAndroidOSWins:
Thanks for that. I read up a lot on rooting, safestrapping, custom romming etc. before I did anything and found out how finicky it is. I'm installing windows 98 on it in a Virtual Machine with Limbo PC Emulator for android, It's pretty cool.:)

dose this really delete all data? i swear i did this like a year ago and it did not delete all data
[Kindle Fire HDX 7" & 8.9" General] DB126:
3.2.8 rollback deletes all data. Other rollbacks/upgrades preserve user data although typically not across major version boundaries (especially rollbacks). Need to remember 3.2.8 rollback was 'captured' when an Amazon representative pushed it to a recently upgraded device at the users request. It is not a normal OTA and was never intended to be used (exploited) in this manner.

My device is a 2013 8.9" Kindle Fire HDX running 4.5.5. I've tried using the rollback file, but I only got an error that says, "Unable to complete update because the update file is not valid. Please try downloading the file again." I also tried to reset the Kindle and transfer and install the file without ever connecting to a wifi network, so I know that's not the issue. Anyone know how to help?

Also, I'm not really worried about bricking it, so if your advice is risky, I'll most likely still utilize it.

- make sure you downloaded the correct file (should be named: mod-update-kindle-apollo-14.3.2.8_user_714328020.bin)

- sideload ES File Explorer (here) and verify the MD5: 51A24CD137A3B5FA321A5A79BF8D6017

Unlikely. Read and ask questions. A HDX is not the device to be cutting your teeth on. Very sensitive; easy to brick; difficult/impossible to recover.

[Kindle Fire HDX 7" & 8.9" General] DB126:

1+ on that, I bricked my first Fire because of OTA update after I had downgraded to 3.2.8. Luckily I was still under warranty and my second Fire is on CyanogenMod 11 currently. :D
[Kindle Fire HDX 7" & 8.9" General] Piita200:
Bricked my device doing this process

Well, I have no doubt that this is because I did something wrong...

So, I followed the instructions and put the rollback file in the internal storage folder using ES File Explorer. I did the downgrade, so far so good. At this point, the device was reset to factory defaults and sitting at version 3.2.8. Once I had it through the bare minimum set up, I went to update it to the next update, 4.1.1 (I think). I have no idea what the firmware version was, though. It went through the update process and then shut down to complete the update...and that was that. It never started back up again. I tried different suggestions, letting it sit for 5-10 mins unplugged and then holding the power button for 2 minutes, nothing. I tried the volume up/down+power button, nothing. I cannot get this thing to come on, it is deader than...well, a brick. I think maybe it probably happened when I tried to update from 3.2.8 to the next update.

Any suggestions? It's out of warranty, so I'm SOL with Amazon.
[Kindle Fire HDX 7" & 8.9" General] DB126:
After rolling back to 3.2.8 your device received an 'over-the-air' (OTA) update which is a guaranteed irreversible brick. There are copious warnings throughout this forum (especially within this thread) about disabling WiFi (or using airplane/flight mode) after rolling back to 3.2.8. There is no recovery. Sorry for your loss.
[Kindle Fire HDX 7" & 8.9" General] Piita200:
I was afraid you would say that. And yes, I did see those warnings and I did heed them...until it was time to do the update from 3.2.8 to 4.5.2. I had wi-fi disabled until it was time to do that update, and I had read so much by then that my eyes were crossing and I missed the very important key word..."MANUALLY" update.

Oh well, thanks for the quick response. That's what I get for trying to do something way out of my league! The word NOOB exists for a reason!
[Kindle Fire HDX 7" & 8.9" General] DB126:
We all mess up; part of life. Wish there was a way to revive your device. No one has found a way yet (don't be mislead by 'unbrick' threads; none work in this scenario). Hopefully you made peace with your Kindle before the untimely demise. Throw it on a shelf in case a solution becomes available downstream.
[Kindle Fire HDX 7" & 8.9" General] Verbank:
hello gents,

Ive done as much research as I can without posting but I simply cant get thor to update to 4.5.2 :(

The downgrade/ rollback worked flawlessly.

- ADB enabled + tested on pc.

- Enabled Airplane Mode

- Slapped the Rollback on the sdRoot.

- Settings>Device>System Update>Update. No issues at all.

I attempted to duplicate the same steps for the 4.5.2 (bin) update and nothing :(

- Ive dumped almost 4 hours in this simple task with multi reboots/factory resets and I cant make any progression :(

Thank you in advance for any further advice or troubleshooting trials !

- Cheers
[Kindle Fire HDX 7" & 8.9" General] DB126:
It sometimes takes FireOS v3 awhile to recognize an update file is available. Sometimes 10-15 min or a bit longer after rebooting.

Other thoughts (if waiting doesn't help):

- assuming you did NOT reblock OTA with HDX toolkit

- check md5 with ES File Explorer (post back if you can't find value in previous posts)

- verify file name matches exactly (didn't get mangled moving the file around)

- enable WiFi as some have claimed this helps. Obviously it is only safe to enable WiFi if your device is in airplane/flight mode (triple check) and/or you have no WiFi profiles active and/or you disable WiFi on your router or are otherwise out of range of a known hotspot.

- use HDX toolkit to root, disable OTA and then reenable OTA (long shot attempt to insure OTA service is running, etc.)

Sorry if the above list seems elementary/unhelpful. Don't have any better ideas at the moment.
[Kindle Fire HDX 7" & 8.9" General] Verbank:
The "long shot" worked ... I would of never expected after at least 5 factory resets that the tool kit (v0.95) would still have an effect.

Read the previous two posts. Your exact question was clearly answered.

---------- Post added at 09:16 AM ---------- Previous post was at 09:07 AM ----------

Keep WiFi disabled (and airplane/flight mode engaged) and you will be fine. You do not need to block OTA on 3.2.8 unless you plan to stay at that version. HDX toolkit is not needed in this context. Just skip all WiFi set up steps the first (and hopefully only) time you boot 3.2.8 on your way to 4.5.2.
