How to downgrade from 5.3.6.4 to 5.3.1 - Fire Q&A, Help & Troubleshooting

I'm currently using Fire 7 5th gen at 5.3.6.4. Is there any way that I could downgrade it to the "rootable" version which is 5.3.1. Thanks in advance!

You can not downgrade below 5.4.0.0 nor root at present.

Same answer; not possible.

Still no solutions?

Hello all,
I followed the above solution and i'm up to:
step 9. Use TWRP to flash custom ROM, Magisk or SuperSU
but don't know what to do at this point to downgrade it to 5.3.1
I tried "Install"
I copied "fire-OS-5.3.1-update-kindle-global-37.5.5.2_user_552153420.bin" on a microSD but It doesn't see the .bin file so i changed it to .img.
I see under "Select Partition to Flash Image:"
Boot
Recovery
But when i tried it they both say "Size of image is larger than target device"
I don't have firmware option
Any help would be appreciated.

Yes you can, as long as your bootloader is unlocked
I assume it's ok to flash this via TWRP 2.8.7.0 (to the recovery Partition of course)?

Thanks, it worked fine.
The screenshot function still creates a 0 bytes file in Pictures\Screenshots though, which can be deleted via TWRP only.
Question:
First run after installation there was a page regarding the option to mount System as read-only with a checkbox whether that page should not re-appear. I did NOT enable (i.e. left it disabled) that checkbox, but I've not seen that page again (regardless if I re-booted into recovery via the extended shutdown menu, or by pressing Vol+&Power at start). Is that option somewhere in the settings? And is it to be considered a bug that the page did not re-appear?

It's not a bug, usually appears on first run only and should not impact TWRP's ongoing use.

New Build is Up
- Dated 29 March 2016
- Fix slow performance especially when flashing open-gapps-6.x packages
- I would urge everyone to update their recovery partition before upgrading to future builds of CM-13.0

How did you attempt to flash TWRP (Safestrap, Flashify, FireFlash)? In the end it really doesn't matter. If your HDX won't progress past the gray Kindle Fire screen it is probably toast. Do you know what version of FireOS was last on the device (3.x, 4.x)?

my hdx7 had been flashed twrp2.8, and flashed cm11. Today, I flashed cm12,but i found hdx7 cant work. So i think it maybe because twrp2.8 is old version.
i used twrp2.8 to flash new twrp3.0........

You failed to read the documentation. CM12 also requires an unlocked bootloader as clearly stated in the OP. That's why it didn't flash with TWRP 2.8. There is no "maybe". Played with fire and got burned.
Since you had TWRP 2.8 installed the last version of FireOS was likely 3.1.x. There is an outside chance your device can be recovered following instructions in the following thread. Good luck.

Before you try @Davey126's suggestion - assuming you're on Fire OS 3.1.x - you should just give the bootloader unlock a try. Zero risk, it either unlocks or fails.

because my hdx7 is second-hand device,i don't know whether it is lock or not.
Before flashed twrp3.0 , it had been flashed twrp 2.8、 cm11. is it means unlock?

Well, to be as clear as possible about this. You had the real TWRP installed, i.e. TWRP 2.8.7.0, NOT Safestrap based on TWRP?
If you had the real TWRP installed you were on Fire OS v3.1.x - v3.2.3.2, which are unlockable versions. Even with Safestrap v3.7x it could be worth a try to unlock.
Again: You can't mess up anything by trying. It either unlocks or fails. And you can try the one-click-solution. Be sure to grab the PDA drivers if you suffer from the good ol' device not found problem.

Newest root-possible Fire OS???

hey! whats the newest fire os version I can root? I have recently got my 7 inch Fire Tablet (5th Gen) and updated it to 5.3.2.1 which is not downgradeable and cannot be rooted so I sent it back and ordered another one which I won`t update ota so I want to know which firmware I can flash but still can root
great would be a link to the .bin file ^^

At of this post (check the date) FireOS 5.3.1 is the highest version that can be exploited with KingRoot on a 5th gen Fire.

On this page you can find the 5.3.1 update file which can be manually installed with ADB. fire-OS-5.3.1-update-kindle-global-37.5.5.2_user_552153420.bin is the correct file to download. Info on how to install:
Jrhotrod said:
Actually, I'm pretty sure that you can easily sideload FireOS 5.3.1 (rootable) from recovery mode easily. Here's how to do it:
1. Go to http://rootjunkysdl.com/files/?dir=Amazon Fire 5th gen/SuperTool and download the AmazonFire5thGenSupertool.zip. Extract it to somewhere where you can conveniently access it.
2. Also go to http://rootjunkysdl.com/files/?dir=Amazon Fire 5th gen/Firmware and download fire-OS-5.3.1-update-kindle-global-37.5.5.2_user_552153420.bin.
3. Now open the Supertool folder you downloaded and run auto.bat. Once everything loads up, select option 1 and when those options load, select option 3 to test your drivers. Depending upon your result, you can install the necessary drivers now or move along as you were. This test can also determine whether you have ADB.
4. Enable USB debugging on your Fire.
5. Plug in your tablet.
6. Now go to the folder where you downloaded the 5.3.1 firmware. Hold down Shift and right click inside the folder. Select "Open command window here".
7. Type "ADB devices" in the window. If a series of numbers appears, then your Fire is recognized and you are good to go. If it says "unauthorized", you may need to turn on the tablet and allow USB debugging from this certain PC.
8. Now reboot your tablet to recovery by typing .
9. Once in recovery, on your Fire select "Apply update from adb". Now go to the Command Prompt window you have open and type:
10. The downgrade will begin in earnest. DO NOT be afraid if it says "patching system image unconditionally" because that is TOTALLY NORMAL and you will be fine. You will know when the downgrade is complete when the menu reappears on the tablet.
11. Now select on your Fire "reboot device now".
12. Okay! You are now in a ROOTABLE ROM! To take advantage of this we need to go and open the Fire 5th gen Supertool once again and this time select option 6 (or whatever it is) and root device now! Follow the onscreen instructions.
BOOM! Done and rooted with SuperSU. Now you can install CM 12.1. Contact me if you have any questions regarding this or the ROM.

You dont need to be on stock to re-install the Nexus ROM. Just use FF to wipe the /data /cache Dalvic ETC, and reinstall the zip.

,
Assume you have tried re-enabling root under developer options to no avail (don't forget to reboot between attempts).
You will need to reinstall/sideload FireOS (same version that was on your device before installing CM 12.1) from stock recovery and start again. Be sure to keep device off WiFi except when running KingRoot; otherwise Amazon will push an OTA update that will block root and any hope of running a custom ROM.

If you go too low your device will brick. If uncertain sideload FireOS 5.3.1 which is the highest rootable build at present. You can find links in the index thread.
Do you recall using TWRP or FlashFire to install CM?

The hardware unlock version should still work ( i am not sure how amazon could block it) The software version just gave you access to the bootrom without opening the tablet. Once you get into the bootrom you are golden to run the bootrom-step script which will give you a hacked fastboot, to allow you to flash TWRP recovery (fastboot-step script). Once in recovery you can flash LOS instead of fw.zip.

I understand that. I'm trying to do the software version instead of opening it. In the software version I get stuck on step 4. and I get this prompt:
mustang:/ $ cd /data/local/tmp

Failed critical init step 4
This platform cannot be supported
So, I assume that the only way to do so is with the hardware version?

Yes , the hardware way is the only way. Opening the tablet is easier than is sounds and shorting it fairly easy too, a wire or a piece of aluminum foil rolled up works well.

Fire 7 9th gen (2019) (thanks @Michajin) -- up to Fire OS 6.3.1.2 build 0002517050244 only
Yes , the hardware way is the only way. Opening the tablet is easier than is sounds and shorting it fairly easy too, a wire or a piece of aluminum foil rolled up works well.

Hello,
Thank you for your help. I managed to install TWRP and Lineage OS 14 with Gapps. However, I removed the micro sd card to change Gapps nano to pico and my device won't boot now and won't be recognized by adb. Did I make this kindle a paperweight?

No, from a power off state you should be able to boot into recovery. I think it's volume up (possibly down) and power button. From there your can go back and flash it again or restore a backup... Are you boot looping? You can fix it. Might need to run the scripts again. But likely you can get into recovery to fix it.

Are you looping in Amazon or los? Or just black screen?

You need to do the hardware hack by opening the tablet.
Start here -
Fire 7 (2019, mustang) unbrick, downgrade, unlock & root

OP says local video playback in LOS is still not supported. Is this still true?

Seems like it was all working. I haven't had it on in months. Make a back up flash it and test it. If you don't like it or it has many issues, restore the backup.

Hello all,
I currently just got a new Kindle Fire 7" 9th Gen. It's running Fire OS 6.3.1.4 Any way that it can be rooted easily and add Lineage OS to it? Or can someone help me out on going to the right thread?
Thanks in advance.

For everyone that has the fire tablet 7 gen 9 , aka mustang , if your tablet was made
in 2020 or later you won't be able to unlock , or flash it .
After 2019 and the first production run , they hardware locked this model tablet.
Starting in 2020 the fire tablet 7 gen 9 aka mustang was shipped with the
chip hardware locked and even opening it up to perform the bypass won't work.
They basically did a bait and switch at Amazon ,
Mid production run for this model they secretly changed the major
possibilities and functions that could be done on it .
Essentially you were buying an inferior unit with the same model number .
Personally I think Amazon should give millions of people their money back for
unethical and wrong business practices being used on its customers.
I talked to Amazon corporate offices and they said that their policy is that at any time
They can modify a current model unit and change its hardware features , all without
informing the customer that their current model being sold was now
with a hardware lock . just like in 2019 , people bought this model tablet , but by 2020
The same model tablet was redesigned secretly to now be fully hardware locked.
People who were unaware like me bought this model in 2020 , and yes it
unfortunately was made hardware locked , but people who bought the first
production run of them in 2019 were lucky enough to buy ones that were not made with any
Hardware lock .
There's different methods to see if your mustang model tablet is locked ,
Either way it all means one thing . your tablet will never be unlocked or flashed ,
At least not without specific engineering , and ROM flashers anyway.
Even then , good luck .
It don't look good .
