I accidentaly upgraded my fire from 5.1.1 to 5.1.2.1
The device was previously rooted.
Is there any way that I can downgrade?
Google services still works fine.
Kingroot is broken.

You need to reload 5.1.2 (can not go back to 5.1.1). See third post in this thread:
http://forum.xda-developers.com/amazon-fire/general/index-amazon-fire-2015-t3210485/page11
I had the same thing happen to me recently. You will just need to do a restore firmware using 5.1.2. You can find the firmware here: http://rootjunkysdl.com/files/?dir=Amazon Fire 5th gen/Firmware Use the file dated 3/17/16. This video is helpful (although my drivers did not install automatically for me, I installed them manually though the supertool makes it easier) https://www.youtube.com/watch?v=RQLoH-ahjy4
Sorry to thread jack but my kindle replacement just came in. It self updated during its stupid backup process. Can I go back to 5.1.1? I am going to guess that it came with that OS.

No, 5.1.1 = Brick.
Sideload 5.1.2 from the replies in this thread.

Yea I wound up just doing a 5.1.2 sideload and it fixed kingroot and all for me. Is there anything wrong with 5.1.2? Seems like 5.1.1 and up lose access to twrp so I guess thats the only difference.
Hi, I need help. Recently bought my Amazon Fire 5 gen. I'm trying to remove the Fire OS and install the CM 11. However, by inattention, I downgrade from version 5.1.2.1 to version 5.1.1. Now my Fire is no longer booting. Is there a solution?
Thanks.

Nope. Contact Amazon (or the place you bought it) for a courtesy exchange.

Likely a permanent brick. What version of FireOS and what actions proceeded the behavior?

At first it had the cm 10 android OS on it and I was trying to update it and after it wouldn't work i tried to restore to before I tried updating and i guess it deleted the fire and android OS it had on it.

See previous post. Didn't pickup on fact your device is a HD, not HDX. I know nothing of that model. Please repost your question in the proper forum.
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.

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.
Hi, is it possible to downgrade FireOS 5.4.0.1 to 5.4.0.0 on a Kindle Fire 5th Gen? If I downgrade, will it brick the device?
I'm not looking for a rootable version, I just want to downgrade it.
Thanks!

We don't know, nobody has tried yet. If they did, they didn't post about it. You could try at YOUR OWN RISK. I'd say it's not a good idea, but if you do try please post back with whether it worked or not. Good luck.

Downgrade from 5.4.0.1 to 5.4.0.0 works fine
Today, I used the adb sideloader to downgrade my 5th gen 7" Fire from 5.4.0.1 to the less restrictive 5.4.0.0. No problems, not bricked. Will post back if I find anything wrong with it. 5.4.0.0 allows you to use shell commands to delete unwanted system apps, for those of you who don't know.

It's the same guy who made the post about 5.3.3 root by flashing SuperSu. Seriously though guys, if you plan on actually using your tablet and not just experimenting with it for fun, don't do this. Especially if you aren't in the 30 day exchange period anymore.

Don't have time to look now; if this guy has a history of intentionally misleading members (potentially leading to bricked devices) will report and let the mods deal with him.
The same went for those reporting it CAN'T be done...new users, a few posts. I try to have an open mind, but unless they're regular users, I take some new user posts with a grain of salt. Always be careful.
EDIT: I did walk one user through trying to downgrade an HD 8 FROM 5.4.0.1, which was unsuccessful and resulted in an unrecoverable brick. It's likely the same thing for the Fire 7.
Hi, new to XDA forums - about 2 weeks ago I came here looking for a way to re-google my fire 7 (which I'd just bought) but mine was already upgraded to 5.4.0.1
I tried to downgrade using a .bin from amazon but it failed during verification so I gave up. Because of this thread I re-downloaded the .bin (which seems to have changed? I'm unexperienced but the update number is different) and tried again.
It downgraded fine and I'm running 5.4.0.0 - I'm honestly not sure what changed but thought I'd put this out there.

It appears the Fire 7 CAN be downgraded, but likely the HD 8 CANNOT be. I don't know how this is possible though. Maybe someone else can chime in about the specifics.
If you are on 5.4.0.0, you can uninstall/disable system apps. So if that's what you're looking to do, congrats...You can still do it

Hi,
this sounds like during the first attempt you used (tried to use) a firmware that was created for the 5th gen fire 7 (codenamed "ford"), not the 7th gen ("austin") that you have. Their names differ in only one place AFAICT: it's a 37 (5th) or a 55 (7th).
While for both device generations there's no 5.4.0.1 for download, someone might have a closer look at the .bins to learn about the hardware differences between 5th and 7th - beyond what we already know.

Awesome! That explains it. The more I learn the better. Also to DragonFire - yes I wanted 5.4.0.0 for system app removal, so it turned out good in the end.

Sorry to repeat this again. But there were some conflicting reports about whether it is possible to go from Fire OS 5.4.0.1 to Fire OS 5.4.0.0. (One report of failure for Fire HD8 (7th Generation)).
Would you please confirm the following steps:
(1). You have Fire 7 (7th Generation, 2017 model) with Fire OS 5.4.0.1
(2). You go to this Amazon site to download Fire 7th Generation OS 5.4.0.0 :
https://www.amazon.com/gp/help/customer/display.html/ref=hp_left_v4_sib?ie=UTF8&nodeId=202144590
(3). You sideload the file from Step (2) above by typing ,from a PC window, "adb sideload update-kindle-55.5.7.9_user_579225620.bin"
Thank you so much.
I am waiting for more reports of success before I attempt to "roll-back" my Fire 7 (7th Generation) from OS 5.4.0.1 to OS 5.4.0.0, so that I can "pm uninstall" most of the Amazon Apps.
My Amazon Fire 2015 downgraded to 5.4.0.0 just fine. Removed OTA updates, Lockscreen Offers, and Amazon Apps.
Nice to know that if in the event a Fire does update to 5.4.0.1, it can be rolled back.

I have a kindle fire that used to belong to my brother and he had it rooted. I did a factory reset and upon registering the kindle it throws me into a language selection loop. I can still manage to get into apps, settings, etc.. if I click fast enough before the language selection pops up again. I'm assuming this is happening because it is rooted and I deleted files that were needed with the factory reset. I believe it's a 3rd gen kindle but I don't know how to be sure. Current version is 13.3.2.3.2_user_323001720 Build date Sunday, June 1, 2014. I prefer it to be unrooted for a fresh start but if it's easier to get past that error loop I'll take it. Can anyone help me with this please?

Sounds like you may have a 3rd gen HDX. You'll need to identify the exact model as recovery procedures differ among the various fire devices.
Bumping this to see if I can get any help on it. I have decided to try again after finding my tablet. The tablet is a Kindle Fire HDX 7 3rd gen. After researching for a while I found out my brother rooted it using SuperSU as there's an su file under system/xbin (my brother doesn't remember anything) but no SuperSU app installed due to the factory reset. I was able to solve the language selection loop error but now I'm stuck on what to do next. Some apps work some don't. I just want to be able to use newer apps/games. Would you guys recommend trying to unroot or can I update current root to something not stuck in a 2014 update?

Reloading FireOS (any build) is not an option on unrooted HDX device. Also rather dangerous without an understanding of compatible versions; a difficult to correct brick can easily result. Re-ask your question in the HDX help thread; someone (most likely me) will respond. You'll need to do a fair bit of work to restore that device including unlocking the bootloader and installing a custom ROM. Not for the faint of heart.
Thank you guys!
