So far as we know, 5.4 can only be downgraded to 5.3.2.1 and that version can't be downgraded any further.
[Fire General] skyla20:
If one was to try to downgrade to 5.1.1 from 5.4.0.0 would it just be a straight brick or if there a possibility? Has another every tried, it would be good to know.
[Fire General] sd_shadow:
Fire would be unfixable with tools we have available
[Fire General] sd_shadow:
If you had 5.1.1, twrp wouldn't have booted.
[Fire General] N01F3AR:
somehow i bricked mine in the process of trying to root and install custom rom. Now i cant even get it to recovery mode or get adb to pull it up in devices list!
[Fire General] DB126:
Did you reload/sideload FireOS just prior to bricking and if so what version?
[Fire General] Jake1702_:
Question: I just noticed on some older topics people have mentioned that at times while root failed with Kingroot on the tab the Windows version worked on older OS versions. Might be a dumb question, but has anyone tried to use the Windows version on newer FireOS releases yet? I assume people have tried it but I didn't see any posts about it.
[Fire General] N01F3AR:
yes i did try to reload fire os 3.1.2. if im not mistaken. its just a hard brick now... i have an exact model copy that i can use to get the scatter files from just cant get it to work.
[Fire General] DB126:
Assuming you meant FireOS 5.1.2 and that a version >5.1.4 was loaded on the device prior to reload. If accurate device is toast. Understand you are trying to rectify that with a scatter file; not going to work with a locked (and crippled) bootloader.

Contact Amazon for a courtesy exchange if still under warranty. Otherwise hold or sell it for parts.

I need to replace a screen in a HD 7 I have tucked in a drawer...just saying.
[Fire General] fax1988:
does ford can unbrick from preloader with AFTV2 tools? I have tryed AFTV2 tools can read memory
[Fire General] DB126:
There are no known unbrick methods. If it can not boot into Amazon's stock recovery the device is (currently) unrecoverable.

Salam Aleykum !!!

hi

how to unlock the bootloader?

for the second year can't find the option on this thing !

thanks in advance !

of equipment tool is CM2,sigma,miracle box,volcano,and many others
[Fire General] sd_shadow:
There is no unlocking the bootloader for 5th generation Fire (s)
[Fire General] N01F3AR:
sorry for the late reply. had put my tablet project off to the side. yes i tried to downgrade the firmware i dont remember which version number i tried exactly off the top of my head but im thinking i might have got the wrong one without paying close enough attention. its still bricked completely.
[Fire General] DB126:
The symptoms suggest the wrong firmware was used. Unfortunately, there is no recovery from this type of error short of replacing the main board.
[Fire General] N01F3AR:
How much you want for mine. Apparently it's a brick now so...
[Fire General] DragonFire1024:
You're about a month late. I ditched it when I got another one, that's rooted and ROMed. I also recently discovered the HD 8.9s so I have a few of those now, rooted with custom recoveries and done with ROMs.
[Fire General] mmar141:
I'd like to restore my rooted fire 7 back to stock. (so that I can access the free amazon content) how do I determine which version to install?
[Fire General] DB126:
You need to know the last (highest) version of FireOS that was on your device prior to rooting and installing a custom ROM. If uncertain install FireOS 5.3.1 which was the last rootable build. Please understand that FireOS will quickly try to update itself to a newer version. Once it goes above 5.3.2 you will no longer have the ability to root.
[Fire General] mmar141:
Is there a way to prevent automatic updates? (sorry for the ignorance, the tablet was rooted 2 days after I got the device so I have no idea how Amazons OS operates)
[Fire General] DB126:
If rooted OTA updates can be easily blocked. Non-root options are limited to software firewalls, router level IP/URL blocks, disabling various Amazon components (aka debloating) or disabling WiFi - none of which are 100% reliable and/or practical for most.
[Fire General] pattyland:
Could OP update the first post to cover fire OS 5.6.0.0? What are the downgrade options?
[Fire General] DB126:
At present none (and likely to stay that way).
[Fire General] pattyland:
Thanks for the information. I’m still hoping for a new root idea. KingRoot shows 0 requests for the fire... this number can’t be correct I think :confused:
[Fire General] DB126:
KingRoot can't distinguish Amazon devices (arugably FireOS) from their generic equivalents. Root vulnerabilities and associated exploits on FireOS v5 were likely based in Android 5.1.1 or common supporting code. Over the past couple years Google has focused on cleaning up sloppy code following several high profile security breaches. The days of 'easy' root are quickly drawing to a close.
[Fire General] DB126:
What is not a good idea - returning it? In the past Amazon has been very generous about in warranty exchanges (one time) not asking what happened or how. That said, the policy may be different on a $50 USD tablet. Can't hurt to try.
[Fire General] lazychai:

Hi guys I'm having the same problem with flashfire, all I get is a blinking CM head. I can only enter fastboot and all the things i've tried don't work, has there been any progress?
[Fire General] Gon Rouge:
It does the same thing to me too! Ive even tried Rootjunky's Supertool to boot into recovery and it doesn't work. HELP PLEASE!

---------- Post added at 07:34 PM ---------- Previous post was at 07:29 PM ----------

Can you return it if you rooted and tried to install Cm-12?
[Fire General] DB126:
Amazon allows a one-time no questions asked courtesy exchange within the warranty window.
[Fire General] smksky:
i have same issue

i have same problem !!!

my tablet is unlimit reboot when i did flash cm12.1 use to flashfire

i can connect just fastmode !!

pls help me!!!
[Fire General] :
Thank you for posting this. I'm just going to link this instead of having to explain everything every time someone bricks their tablet.
[Fire General] Jimseyed:
Definitely worth pursuing a replacement from Amazon, the call centers ask very few questions and usually try to be helpful.

A possible precaution for a modded return would be to return it with the battery totally drained. My (probably wrong) thinking is they are less likely to bother recharging it when they get the return to check it. Use an elastic band to hold the power button down and let it totally drain overnight.
[Fire General] lh94:
So what should I told them? That I bricked my device or that it just stopped working suddenly. And how did they resolve it for you? Send you a new tablet?
[Fire General] sd_shadow:
Tell them you bricked it, they don't care, but it's a one time replacement, next time no replacement
[Fire General] Jimseyed:
Or it won't switch on, etc.
[Fire General] lh94:
Just found out that it was out of warranty. Guess I'm stuck with this brick for now. :( Unless anyone has a different suggestion?
[Fire General] shabuboy:
How can you be out of warranty? Amazon Fire was released on Sep 2015 and since it has a 1yr waranty, makes no sense. Unless you have a different device and are in the wrong forum.
[Fire General] lh94:
They said it has only a 3-month limited warranty only. I also asked them about that since it said on the website that I still have a warranty but the guy I talked to said that it's "limited warranty". I might need to speak to someone again.
[Fire General] DB126:
Product description says 90 days. Question becomes when the clock started, time of purchase or first use/registration (likely the former).

90-day Limited Warranty and service included. Optional 1-year, 2-year, and 3-year Extended Warranty available for U.S. customers sold separately. Use of Fire tablet is subject to the terms found. here​

---------- Post added at 06:14 PM ---------- Previous post was at 06:07 PM ----------

For now. A solution may come down the road as more devices meet a similar fate. Sorry this happened - your experience may help others banking on a warranty coverage (I know - small consolation given your current situation).
[Fire General] DoLooper:
Whoa! Glad you posted this. I had no idea. Better get some seriously naughty testing done in the next month or so! :angel:

FWIW, I called a while back for warranty end-date on my 2014 and was told warranty period starts upon registration.
[Fire General] rigels89:
HI guys. I tried to flash CM12.1 with flashfire with slimp SlimLP installed also with flashfire Unfortunately, it loads the CM boot logo, and getting stuck. I tried to use recovery mode by holding down volume up, and the power button, but it is blocked with amazon logo and "adb devices comand" showing nothing on cmd . I can get it to fastboot mode holding the volume down and power button , but i cant use TWRP recovery because i have Fire OS 5.1.1. So i have a bricked tablet!!!

Now trying i think i found a way to get SEMI-acess to recovery.

If I turn on the tablet until CM logo , with usb cable connected to the tablet and then turn off the tablet until the logo of the battery charge, in adb shell program i get this message

adb devices
List of devices attached
XXXXXXXXXXXX unauthorized

when i try

adb sideload update-kindle.......
loading: 'update-kindle.........
error: device unauthorized.
This adbd's $ADB_VENDOR_KEYS is not set
Otherwise check for a confirmation dialog on your device.

Anybody can help me????
[Fire General] DB126:
You are not alone; a handful of others have experienced this problem with no known resolution. If your device is within the 90 day warranty period contact Amazon for a 1-time courtesy exchange.
[Fire General] rigels89:
I bought it 4 months ago

so there is no way to get authorized through the adb or fastboot comands?

[Fire General] hp420:
is this possible with a 7th gen running 5.4.4.0?
[Fire General] DB126:
I know nothing of this FireOS variant. What's the issue/problem and how did the device get into that state?
[Fire General] hp420:
the issue/problem is this damn thing is stuffed to the gills with bloatware and lockscreen ads ? i'd like to roll back to 5.3.x because i've heard there is a root solution....just want to be sure i can do that on 7th gen without risk of bricking my brand spankin new tab ?
[Fire General] DB126:
No root or rollbacks below 5.4 on 7th gen devices. Not much you can do about the slop. There's a bloat killing script for those in 5.4.0.0 and below but it's rather brutal without some tuning. Lockscreen ads can be dismissed free of surcharge via note to Amazon support. Search the 'general' section of this forum for details.
[Fire General] speaker1264:
So I seem to have soft bricked my device. I was trying to flash from the Fire Nexus ROM to the Lineage 12.1 ROM when my tablet bricked. Not sure what went wrong exactly. Anyway, I bought the tablet back on Black Friday 2015, so I'm pretty sure it had FireOS 5.1.1 on it when I installed my first custom ROM back then, though I guess I'm not 100% positive it didn't have something newer like 5.1.2 (Not sure the exact date on that firmware). So when I try to unbrick it should I use the 5.1.1 firmware or is it better to just use the 5.3.1 firmware instead? Are there any pro/cons?
[Fire General] Hallo32:
Get the version of your bootloader and flash the FieeOS version with the same bootloader.
[Fire General] DB126:
Great question and awareness of potential liabilities. IMHO you should go with FireOS 5.3.1 as there are no advantages to preserving the 5.1.1 or 5.1.2-5.1.4 bootloader. Be sure to maintain network isolation until rooted and OTA blocked (or Nexus/LOS reinstalled) as the next bump will yield an unrootable build of FireOS.
[Fire General] speaker1264:
Thank you for the advice, I will try it and see how it goes.
[Fire General] speaker1264:
Edit: Ah, my device isn't bricked. Dunno why but it wasn't booting before, but now it just did.
[Fire General] DB126:
Good! I saw your previous (now removed) post and will advise you made some missteps that aggravated the situation. Root is no more difficult to secure on FireOS 5.3.1 but you have to go about it in a specific way if the ultimate goal is to install a custom ROM. Intermixing KingRoot and SuperSU is just asking for trouble. Hopefully by now your on a custom ROM w/recent rooting headaches just a bad memory.
[Fire General] Lucidioebb:
I want to update my fire to the latest version. My fire is on 5.3.1.0. it was rooted, but after a factory reset it doesn't download or process sideloaded update. What are my options?
[Fire General] DB126:
Updating to the latest version of FireOS is relatively easy if you wish to retain FireOS (including all associated Amazon apps/bloat) and forgo any future opportunity to root and/or install a custom ROM. Simply grab the latest FireOS build from here and then follow the instructions on that page for manual installation.

Alternatively, you can reroot and install a custom ROM (operating system) which will offer a much better experience - both device performance/responsiveness and access to a much larger app portfolio. In short your device will become a 'standard' Android tablet.

Although enthusiasts will argue otherwise there is no 'right' answer. FireOS is not horrible and is a better fit for some. That said, Amazon's designed Fire tablets (and FireOS) to be a captive portal to their vast ecosystem and that's what you'll get.
[Fire General] Lucidioebb:
Tried twice the instructions and doesn't work. For some reason the Fire don't download the updates automatically or process the update files.
[Fire General] DB126:
In that case boot into stock recovery and apply then update via adb sideload. You will need tether your device to a suitable (usually Windows) host and get comfortable operating in a command window. See linked video for overview.

[Fire General] jeebob:
are we still in a position we do not have any means of rooting and unlocking the bootloader on the current OS?

Is it me or have amazon locked this thing down so tight, its impenetrable?
[Fire General] DB126:
Yes and yes - just like most other modern devices.

I was on 5.3.2.1 and didn't know I couldn't downgrade. I ran the downgrade to 5.1.1 and rebooted, nothing shows up any more no matter what buttons I hold, but when I plug in the tablet it connects for a few seconds then disconnects and loops. Is there any way to recover back to factory firmware
[Fire General] sd_shadow:
No fixing
[Fire General] DB126:
Device is toast; keep or sell for parts.
[Fire General] Hallo32:
Contact Amazon and see what happens.

The weak point in the argumentation is, that it is their recovery which is applying a signed Amazon firmware to their device and brick the tablet as result.

No error message, no warning, simple nothing to warn the user.

The recovery has a design mistake, because it doesn't check if the bootloader of the signed image is compatible to your device.
[Fire General] DB126:
While it can't hurt to contact Amazon the typical 'accommodation' is a modest discount on a new/refurb unit for out-of-warranty claims.

Amazon does not endorse or support rollbacks. Older builds of FireOS are not offered on their support site. They are well aware of the "design mistake" as it has existed since 3rd gen devices (2014). They choose to keep it that way.
[Fire General] Hallo32:
At least in my location it matters which service person you are getting. If you get one of the "general department" they may be only able to send you a refurbished unit in the waranty period. If you hit someone from the dedicated(?) tablet department it may end in a nice and very productive call.

Does this guide also work with an older firmware? https://www.amazon.com/gp/help/customer/display.html?nodeId=201642370
[Fire General] DB126:
The builds offered through this support channel are equal to or greater than the latest FireOS build pushed via OTA update. Bricking due to incompatible bootloader is never a risk unless you have retained/use an older build.
[Fire General] Zed79:
Hello all. I bricked and then unbricked my Fire tablet successfully restoring it to 5.3.1. I am using RookJunky's tools and I cannot get the device to root again. It installs KingRoot and fails to root. I also tried the standalone KingRoot app on PC. Is it possible that something was different in the 5.3.1 bin file I used and I can't root now? Any help is appreciated.
[Fire General] DB126:
KingRoot is very erratic. Sometimes it roots in a few tries; on other devices it takes dozens of attempts. Suggestions:

- factory reset

- during FireOS initialization do not provide Amazon credentials

- if possible do not provide WiFi credentials; if you do be sure to disable WiFi immediately to avoid an unwanted OTA update

- on each KingRoot run enable WiFi (make sure it connects) for 30-45 seconds; then disable (to avoid OTA updates from Amazon)

- if rooting fails reboot and try again

- as a last resort try installing/running the latest build of Kingroot from here (it's usually best to use the older build packaged with the SuperTool).

Good luck.
[Fire General] Zed79:
Thanks for the help. It was a headache and very glitchy, but I got it rooted again.

1. I had to hard reset because the soft reset would not respond and could not uninstall KingRoot

2. WIFI was very glitchy (didn't want to connect) and KingRoot would hang even after several restarts.

3. Did a soft reset, WIFI worked and KingRoot worked on the first try withinol.-ppppppppppppp just a couple minutes.

I only connected to WIFI just before I started KingRoot.

Hopefully this will help someone else. Thanks again!
[Fire General] Inexplix:
Boot into recovery, select apply update from adb, use adb devices (get the correct response, use adb sideload filename (bin file is in same directory), sideload begins but then after a while I get "D:\Delivery Box\platform-tools>adb sideload update-kindle-global-37.5.4.2_user_542168620.bin

serving: 'update-kindle-global-37.5.4.2_user_542168620.bin' (~19%) adb: failed to read command: Connection reset by peer"
[Fire General] DB126:
Thoughts:

- if the error always occurs at 19% it's either a: 1) tablet timeout; or 2) bad/invalid file

- if error occurs erratically it's likely a cable/connection issue; try a different usb cable

File you are trying to sideload appears to be FireOS 5.1.2. Are you certain that's the one you need/want? If the version is wrong device will brick with no possibility for recovery. What version of FireOS was last in use?
[Fire General] Inexplix:
I'll try other usb cables. It is a erratic event.

Yes, I'm sure 5.1.2 is what was on the device last. I did the checking of the hex code as you suggested and 5.1.2 is the result.
[Fire General] DB126:
Great - done your homework. :)

Other connection tips:

- try to avoid USB hubs (especially external hubs) and USB3 ports on older machines (Fire port is USB2)

- verify connect is snug at both ends; don't press too hard on Fire side; port is easily damaged

- USB quality varies widely; if a second cable doesn't work give others a try

- sustained adb sideload transfers are susceptible to error; might take a few attempts
[Fire General] Inexplix:
Tried a different cable. Still failed. Moved the cable from a rear port to a front port. Seems to be working now.
[Fire General] steve_togo:
I am currently rooted with Cyanogen on it. Can i go ahead and install the latest firmware? If so would I loose the root. I would like to have access to play store.

Thanks
[Fire General] sd_shadow:
Yes you can install the latest firmware, yes you will lose root.

Fire OS 5.3.1.0 was the last rootable version for all Fires,

except the HD 10.

Do not attempt to downgrade.

Whatever official firmware the device was on before CyanogenMod, that is the version I would install

Do not attempt to downgrade from that version.

Restore original firmware

Hi, i have lineage rom on my tablet (ex cm 12.1) and i want to go back stock firmware, this solution is secure? Or cause brick? Thank you
[Fire General] sd_shadow:
This method works, as long as you do not downgrade.

Use the same firmware (or newer) that was on the device before installing custom firmware.
[Fire General] sd_shadow:

5.3.1.0 is the safest rootable version, if original firmware is unknown.
[Fire General] thisguyneil:
Hi,

I’m a bit late to this party, I just recently bought the fire 5th gen from woot for $15 knowing the rom community for the device I knew i could do something with it. I have never had one if these tablets and when first turning it on the automatic updates was turned on and it updated to 5.6.2.0. Then upon reading online I find out that you can’t root on this firmware version, and I’ve also read that downgrading the firmware can brick the device. Am I screwed? I haven’t rooted or done anything to the tablet yet, but damn fire launcher is terrible.
[Fire General] DB126:
You can install the Google Play store on any FireOS v5 build or downgrade to 5.4 (no lower) and use various scripts to 'debloat', ie: hide many pre-installed apps. With additional a third party launcher can be installed. That said, device will be a dog no matter how much clean-up you do. Good luck.
[Fire General] thisguyneil:
So I’m assuming that’s a “no” on the rooting or custom rom question.

Can I downgrade to a rootable version without bricking yet
[Fire General] Rortiz2:
You cannot downgrade from 5.3.2.1 to 5.3.1

If you are in 5.6.X you can only downgrade to 5.3.2.1 if you do it more your fire will brick
[Fire General] Lancey6969:
What can I do with 532 you know

Without root you can:

- Change launcher

- Remove ads form lockscreen

- Uninstall amazon bloatware

- Disable OTA Updates

- Install Google Play

- And more things
