Installing custom rom with FireOS 5.3.1.0

I have FireOS 5.3.1.0 on my 5th gen Amazon tablet and I want to put Cyanogenmod on it. I understand that I need to first go back to 5.1.2 in order for TWRP to work but I'm also seeing reports that going back to an older version bricks the device. Is it possible to put a new rom on this device? If so, does anyone know where I can find a how-to?

- 5.1.3 can be successfully rolled back to 5.1.2
- 5.3.1 is new; consequences of a rollback attempt are unknown
- twrp is not an option (period); you'll need to use FlashFire for managing custom roms

I tried, despite the warnings, and with knowledge that it could be "fatal", to put 5.1.2 on a 5th gen Fire that had 5.3.1.0 on it. It's now bricked. Only comes up to the MediaTek MT65XX PreLoader, loops on that, never shows anything on the screen. Don't do what I did.

Thank you for sharing your findings. This small, selfless act will help others avoid a similar outcome. A respectful head nod to your device for paying the ultimate price.
@sd_shadow, @ggow - FYI.

It may still be possible to re-flash 5.3.1 bootloaders via AFTV2 tools ... But right now the best route is to talk to Amazon

F&$! Sorry about that Keith. I also have a Fire 2015 with 5.3.1.0 on it and Android 5.1.1 and I've only been able to put google apps on it and not been able to root it at all. I think you may be able to save it. Let me know.

I bought two tablets during Prime Day, both came with 5.1.4. I mistakenly accepted the OTA system update for 5.31. on one of the tablets, and couldn't find a way to root or downgrade (I was only able to install google play/apps). After doing a factory reset, I exchanged it at Best Buy (no restock fee!) for a tablet with 5.1.4.
I have since successfully downgraded both tablets to 5.1.2 using RootJunky's tools (Search YouTube for a video by RootJunky titled "How to Firmware Restore or Unbrick your Amazon Fire 5th gen Tablet "), and then I followed the steps from talesofatech.com from the articles list below, to root and flash to an AOSP rom.

NOTE: the above statement refers to downgrading 5.1.3/5.1.4 -> 5.1.2. It does NOT apply to higher versions of FireOS. At this time there is no option to downgrade 5.3.1.x to a lower (rootable) version. Any attempt to do so will likely yield a brick.

Many people have done that (I am one). I think it's misleading to have 5.1.3/5.1.4 posts in the 5.3.1.x thread.

Read the warning too late about the 5.3.1.0 OS and now my Fire HD 8 tablet is bricked. Any one know how to get it back working again? It was 5.1.4 just the other day and I decided to downgrade today, but did not think of checking the OS version and end it up bricking it.

Hey that's awesome. Mine came with 5.3.1 also. Can't root yet but I have google play store etc... I have a rooted Kindle HD I bought in 2012 I actually like a little better than this new one that's rooted. Hopefully there will be an update for the 5.3.1 someday. I'm glad you were able to get those down graded, it sure feels good when stuff just works right !!

Suspect that was one if the first things tried as there is typically no risk associated with root attempts (the payload included with some rooting apps is another story). Beyond that several have analyzed the security 'fixes' incorporated into 5.3.1 and concluded previously leveraged exposures have been closed while others have yet to be exploited. You can bet Amazon will be working to close those too.

argh... received a 5.1.4, and red to late the downgrade option to root. Tried King root, it said a root option would be possible. So I upgraded the fire tablet to 5.3.1.0 in two steps und tried in both king root... nothing worked. So I also have to wait for a new freaky instruction to root a fire 5.3.1.0

Welcome to Amazon's world. First rule: never update FireOS if you care about root (there are exceptions; too many caveats to detail). Second rule: ask before acting as likely someone before you has fallen into the firery pit and has a helpful tale to share.
In your case FireOS 5.1.4 was just fine - could be rolled back and rooted. 5.3.x not so much. Live and learn.

Any root/slim ROM method for Fire 7 (7th generation 2017)?

I just bought a new Fire 7 (7th generation) tablet. But all I found so far were for root is for Fire 7 (5th generation). Any new 7th generation root method and custom rom? Or is it compatible between 5th and latest 7th generation? Thanks for the help guys.

If the OS Version is 5.3.2.1, or 5.3.3.0, then no...not root yet.

In addition to other responses no assessment of custom rom compatibility on 7th gen devices can be conducted without root. IMO it is highly unlikely an exploitable vulnerability will be found in recent builds of FireOS or the device bootloader anytime soon given recent efforts to shore up all Android based ROMs.

I just got 4 Fire 7 gen 7s in the mail today; two with a red case, two with a yellow case.
The odd thing is that the yellow colored ones came with 5.4.0.0, while the red ones came with 5.3.3.0. The red ones must not be as popular and I was sent slightly older stock I assume.
Even worse is that the 5.4.0.0 yellow ones won't even let you bypass/skip the initial wifi setup and amazon account login. You MUST be connected to the internet and login with an Amazon account to setup the tablet.

I would highly advise you not allow those to update, flash 5.3.2.1 (the oldest version you can safely revert to if you haven't yet hit 5.4.0.1), and then use the tool linked below to remove all of the Amazon bloatware and install the launcher of your choice. This will get you as close as possible to a stock Android experience.

Unfortunately, these are the 7th generation Fire 7 tablets (not 5th gen 'ford'). AFAIK, the earliest initial firmware shipped with these gen 7s is the 5.3.3.0. Even worse, is that I've tried to adb sideload every firmware version since 5.3.2.1 (even tried 5.3.3.0), but I got the same error every time at 47% progress:
"whole-file signature verification failed"
"aborted"
On that note, do you or anyone know if there is a way to adb sideload older firmware versions to a gen7? I was using the Windows 10 built-in USB drivers and that seems to be working but I have read elsewhere that the newer Fire generations require the Amazon USB ADB drivers to communicate properly with the computer. So my next step is to try using the Amazon USB driver and try again.

Bootloader is locked and anti rollback measures are in place. If you are on 5.4.0.0, the lowest you can downgrade to currently is 5.3.2.1. Trying to go lower will result in a hard bricked tablet. Look at it this way...if you want to experiment, knock yourself out. If you do brick it beyond repair, you have 30 days from date of purchase (or delivery? Not sure how that works) to return it for another. Just get a color you haven't gotten and who knows what those are on, if the event you described regarding colors is true.
EDIT: I am in no way encouraging you to brick your device or do any harm to it.

haha, nice edit.
Well I read your previous post stating that downgrading to 5.3.2.1 was possible, but I get the same above error trying to sideload any version firmware file to it. I am assuming this is because I am on the gen 7 (aka austin), not the gen 5 (aka ford). I have done some extensive searching on xda but it seems not many people actually have a gen 7, so I think I'm pioneering this a little bit.
With that, I can say that the Amazon USB driver for ADB made no change. Any ideas?

I truly appreciate your time into this, however I do not think I am explaining myself well. The ultimate purpose of these 4 gen7 (austin) tablets is for all 4 to be rooted and use a custom ROM. On one of the 7gens (5.3.3.0), I have successfully removed bloat from the stock rom and installed the play store (using your guide and others :good: ). It's much better than stock, but still not applicable for my purposes.
This leaves me with one option; downgrade the firmware to a rootable version (ideally 5.3.1). To do this, I enter the recovery menu by holding the volume down button and power button when powering on the tablet. While in the recovery menu (yellow on black text), I attempt to sideload firmware (any version, with md5s matching) and get the same error every time on all 4 tablets at exactly 47% completion:
"E: failed to verify whole-file signature"
"E: signature verification failed"
"installation aborted."
This doesn't brick any of the tablets and they reboot just fine out of recovery into the stock firmware. It must have something to do with the 7th gen tablets. While connected via USB to the tablets while in sideload mode in recovery, the hardware ID for the USB connection shows up as "USB\VID_1949&PID_0001". After googling that a little bit, it kept coming back to HD8 drivers! Soooo maybe I need the HD8 version of the firmwares so I can downgrade? Hmmmmm.....

I have no idea. Regardless, you CANNOT downgrade to anything lower than FireOS 5.3.2.1 (which cannot be rooted). If your tablets are on 5.3.3.0 or 5.4.0.0, the lowest you can go is 5.3.2.1. If you are having ADB trouble, I would download Android Studio full version and make sure the SDK is up to date and start a new ADB folder from there. If your Kernel is of a later date than June 2017, you might not be able to rollback at all.

Have seen this before (crap out at 47%). Usually pops up when attempting to sideload an inappropriate '.bin' file. Likely the 5.3.1 build you are using is for 5th gen devices. Different mainboard/SOC than 7th gen. Be happy Amazon's firmware detects this and doesn't allow the device to brick.

Ohhh I understand, so even if downgrading to 5.3.2.1 actually worked, I can't even root on that firmware anyways. Ugh, well I will be patient. Thanks for the info and your time.

If your goal is to have these all ultimately rooted, I would return them and get your money back (if you still can). It's not likely a root method will be found.
This isn't a hot new device like the Pixel 2 where hoards of talent will be flocking to try and make it more usable. I got mine second hand for 25 bucks, this device from a monetary standpoint just isn't worth anyone's time.
The only realistic way I see root happening is if they release firmware based on a new version of Android or Kingroot find an Android exploit that would be compatible with our device.

Correct...but keep in mind, so far it seems anyone on 5.4.0.1 won't be be able to debloat anymore. So downgrading to 5.3.2.1 is a better option than being so close to the latest version.

I'm not looking to root (i am, but i understand its not possible right now)... So is there any possibility to install apps other than the amazon app store?

Amazon Fire 5.4.0.0 rollback to 5.3.2.1

My tablet just jumped from 5.3.2.1 to 5.3.3.0 in one day. I tried kingroot several times hoping it would work. It did not. I performed factory reset on it and signed into amazon. When i woke up it was at 5.4.0.0. My question is if a root exploit is found for 5.3.2.1 or 5.3.3.0 can it be rolled back? This all started from a bad SD card that kept resetting my old fire. I thought there was something wrong with the tablet and bought a used one off eBay hoping it would come with 5.1.2. I love AOSP on these machines.

If I recall correctly, 5.3.3.0 COULD be rolled back to 5.3.2.1. And 5.4 supposedly, or theoretically can be rolled back to 5.3.3. So theoretically, yes it could be rolled back to 5.3.2.1 from 5.4.

Hello guys. I really appreciate what is done on this forum. Keep on doing it, it really helps a lot of people out there. I would like an explanation on how to roll back from OS 5.3.3.0 to OS 5.3.2.1 on Amazon fire 7" 5th gen. Thanks

Hey, do you have a link (or tips) to how you did this? I have 5.4.0.0 and the advice I'm getting is that this system version cannot be rooted or downgraded, that trying will brick it. You're the only one who seems to have had success. The follow-up link given by someone else (https://forum.xda-developers.com/ama...h-gen-t3285294) doesn't have a shred of info on 5.4.x.x.

I just downgraded to 5.3.2.1 from 5.4.0.0 i have never acheived root. You gain nothing by doing it. I did it just to see if i could. Hope that helps.

You're the only one who seems to have had success. The follow-up link given by someone else (https://forum.xda-developers.com/ama...h-gen-t3285294) doesn't have a shred of info on 5.4.x.x.

Clarification: you can not downgrade from 5.4.x.x+ to a rootable version of FireOS as of the date of this post (5.3.1.0/5.3.2.0 are the highest rootable builds). Amazon updated the bootloader concurrent with delivery of FireOS 5.3.2.1; manually rolling back to a lower version will brick the device. At present there is not a method for downgrading FireOS independent of the bootloader on an unrooted device.

Probably 'yes' based on a couple user reports. However, there is no benefit to offset the potential brick risk if the version of FireOS currently on your device has an incompatible bootloader. 5.3.2.1 can not be rooted so what's the point?

I downgraded. I had the system updates uninstalled so have no clue if it worked but I downgraded anyways because root might be found in a different method and got patched? have no clue and no suspecting it. Just proving that dowgrading is safe from 5.4 to 5.3.2.1

I believe you can find the 5.3.2.1 software here. I believe all you have to do is place the .bin into the internal storage (SDcard) and boot into recovery to flash it. I'm not 100% certain though.

You download the 5.3.2.1.bin file from rootjunkysdl.com and adb sideload it

Hi can i rollback from 5.4.0.1 to 5.3.2.1 ? or to 5.4.0.0 !?
Edit. The the rollback from 5.4.0.1 to 5.3.2.1 has worked well .

Any news in the community about a 5.6.0.0 rollback?

Prevent 5.4.0.1 install after download and shutdown?

So my unrooted 5th gen Fire HD7 downloaded 5.4.0.1 and I mistakenly shut it down.
When it restarts it will attempt to update. Is there any way to stop this?
Thanks

If you can't figure out how to prevent it, you can use the sideloader and a firmware file to downgrade back to 5.4.0.0. I tested this today on my Fire 7" 5th gen, and it worked fine.

I follewed Davey126's suggestion (booting into stock recovery and clearing cache) and it worked. :good:

Have you tried this yourself? ie, downgrading 5.4.0.1 to 5.4.0.0 on a 5th gen Fire 7? I'm sure I read someone tried this and hard bricked their tablet?
I have second Fire 7 which has already updated to 5.4.0.1 so would like to downgrade if possible.

One user reported a hard brick after attempting a 5.4.0.1->5.4.0.0 rollback, another claimed complete success with no side effects. Both were new XDA members with limited post history. TTBOMK those are the only two data points. You would certainly be taking a chance attempting a rollback without more supporting evidence that it works.
Edit: also see this.

5.6.0.0 root?

I have had my Amazon fire 5th gen for a couple months now and I want to know if there is a way to root my tablet without a computer, anybody know?

Neither without, nor with a computer. The last rootable firmware was 5.3.1, long ago.

You can't as a quick of the dozen+ threads on the same topic would reveal:
- no root on any build of FireOS above 5.3.1
- 5.6 can not be rolled back to a rootable build

@Nrocket3 Downgrading will brick your device unfortunately

Unfortunately, no root once FireOS has progressed beyond 5.3.2.0. Status quo for many months and is unlikely to change going forward. You can still install the Play Store and ask Amazon to remove lock screen ads. That's about it.

You can root from FireOS 5.4.1.0 all the way to the current 5.6.0.1, on the Fire HD 10 only. At the moment no other current (2017) tablets can be rooted. I plan to reload FireOS on my HD 10 sometime soon to re-root and see if I can't get some logs of it and see what's going on. The closest to root any other Amazon tablet has, beyond 5.3.1.0, is disabling system apps on 5.4.0.0 and earlier versions.

Seen this movie before. HD 10 uses a different architecture (64-bit) utilizing different binaries with different vulnerabilities. It is unlikely that any exploits from the HD 10 can be leveraged to FireOS builds for the Fire 7 and HD 8.

Agreed. Though to see what's going on, could be beneficial. Though I do giggle a little at the thought of Amazon "patching" the disabling of system apps, only to have their most expensive tablet rooted. I have been wondering if whatever they patched caused this.
I don't really know how kernels are patched. Example: when a kernel is patched to stop potential exploits, how is the data written? Like is it in rotation? As new patches are uploaded, does it push off the older data?
