Hi, I have a problem. Trying to install a rom with flashfire I brick my tablet. I have an Amazon Fire 7 5th gen with firmware 5.1.1.
The tablet doesn't start and I need some solution to restore it. I tried to access the recovery mode to restore it but it doesn't exist. I have bootloader and fastboot in my tablet and I can run it in my PC.
Is there any way to restore the tablet using the bootloader and cmd?
Can I install some recovery using bootloader?
I really appreciate your help.

Access to stock recovery is the only way to recover this device due to locked bootloader and crippled fastboot command set. If you nuked access to stock recovery then it's game over.

Is there a reliable way to backup one of these? I'd like to mess around with some ROMS, but can't find a way to backup the system files, at least at 7.2.3. I would even be willing to install a previous update if that is at all possible. Thanks!

To doing a good an consistent backup you need to root your device. You can search on this forum how to do this.
Regarding doing a backup, once you have you device rooted you will find some apps to do this. You can read the CM10 thread and you will find an APP to backup your system.
Unfortunately, due to having a locked bootloader and no custom kernel created for the HD7, installing custom ROMs is not available at this time

I didn't try it, but there is a tread to install a 2nd boorloader and custom recovery http://forum.xda-developers.com/showthread.php?t=2128848
Until I've find a way to boot into recovery I didn't try it, because so I can't restore it.
I also know, that a someone make a CM 10.1 Rom for KFHD 7 inch. But it is still in alpha.
Bootloop?
When I boot up the Kindle there are no problems, but it goes straight to TWRP recovery page instead of booting Kindle OS. The OS was 7.4.6.
That's because the is version doesn't match the freedom boot version so you have to put the ROM on ahead of time or you will have to use adb to push the image onto the device's sdcard. Here try this tutorial to get a ROM onto it: http://forum.xda-developers.com/showthread.php?t=2459498
This is all due to Amazon's attempts to annoy us, the newer OS's check to see if the boot loader is the same version as the os... And since we flashed an older boot loader and used a older version of freedom boot, this happened. There is a newer version of freedom boot available inside the kinology ROM u can extract and flash if you want to boot back into stock amazon, but I would disable ota's if you do so it does get rid of 2nd boot loader + twrp if it updates.

I have a Kindle Fire HD 1st Gen and I've been trying all day just to get rid of TWRP and get back to stock Amazon ROM. I tried flashing TWRP 2.2.2.1 zip, but apparently anything I flash there's an error and says couldn't find /sdcard/kindleupdate/whatever. I've downloaded KFU 0.9.6 and I have Java and SDK/ADB installed. When I try and install the drivers I get an error with an "X" next to Google (WinUSB). When I hit run.bat it says I'm online, but the device is unknown. My device won't go into fastboot anymore, it will just say on the prompt "kindle fire has been told to boot in fastboot mode" and then after that the kindle reboots and I get stuck with the light blue twrp "kindle fire hd" boot logo. I heard that TWRP 2.6.0.0 sucks because it won't flash the Amazon stock rom and that TWRP 2.2.2.1 can flash the stock rom. So I started searching on how to downgrade from TWRP 2.6.0.0 to 2.2.2.1, but everything involves kindle fire utility and root and all this other stuff that doesn't seem to work. I'm just really frustrated and fed up at this point. Why is it so difficult to get Kindle Fire Utility to install my drivers correctly and get into fastboot?
My main objective is to remove TWRP and just get back to Amazon stock OS so I can sell the darn thing.
Yes, I've searched on youtube and on xda on how to fix the driver issues/fastboot all day, but nothing has worked.
I'd really appreciate it if someone could give me some detailed steps on how to fix all of this. I wish I hadn't installed TWRP at all if I'd known it was this difficult to flash a rom.

What firmware are you running? This matters because in order to get rid of TWRP, you will have to flash an Amazon image via fastboot to get rid of the second bootloader. This will put you back to stock. Knowing your firmware is imperative or you can flash yourself into a hard brick.
Hey guys,
I rooted my Kindle Fire HD 7" (Tate) and installed a second boot loader and TWRP recovery. I installed CM11 but actually preferred the Amazon Fire OS. I tried to restore my backup from TWRP recovery, but I think it restored the boot partition badly. It now just flashes the Orange kindle fire logo, then reboots and does the same thing again and reboots etc. etc. Is there a way I can restore a Stock Fire Os Rom from my PC now or get into fastboot and re flash the boot loader (The files are in the downloads folder)
Thanks!
Could someone please suggest something? Even telling me it's unfixable and I've got a perma-brick would be helpful. Thanks!

Don't worry,it's fixable. Though you'll need a fastboot cable. Then you can restore it. And I recommend using CM since Amazon OS makes problems with the 2nd boot loader.

Thanks for this SafinWasi, do you know where I could get a FastBoot cable??? (I live in the UK) I know how to use FastBoot as I've had to use it before when I flashed the wrong recovery image
Just purchase a fastboot cable via eBay and use kfft restore tool
I managed to brick my recovery by trying to install the TWRP_Fire_2.8.7.0_adb.img to the recovery partition. Does anyone have a stock recovery image? :angel:
I already have root permissions, so installing it should not be the problem, but a way to correctly install the recovery would also be nice...

Root is irrelevant. Without a signed image you are going nowhere. Have not seen any of those floating around.

Do you have a fire tablet?
Can't you simply dump that partition and write to another/my device?
Found a stock recovery by accident. There is one within the Supertool download. I flashed it and now the recovery is working again.
So may it is a bad idea to tamper with the recovery if the boot loader is locked...

Cool - thanks for sharing. Didn't know this was possible but thinking through it now makes sense. On some locked devices you can't touch the recovery partition but since you 'successfully' borked yours through intentional action it demonstrated some ability to manipulate the contents. Nice when it works out that way.
I don't know how the bootloader lockdown works, but I thought it is similar to uefi. So the boot process is verified by certificates or hashes. So the binaries that are loaded at boot cannot be changed.
In addition, the fastboot does not allow you to flash images.
So as by uefi if you have an booting system (live cds) you can tamper with the contents on the disk, but if you tamper with boot files, the system would not start.
So i did a dd (without backing up my current recovery...) and overwrote the recovery partition from the normal boot mode using my root access. But the recovery image didn't succeed the bootloader checks and didn't load therefore.
I guess, if you find an unprotected part of the recovery to overwrite from where a program would be called as root, it could modify the recovery on the fly...
But that's mostly unproved thoughts based on research and tampering on uefi...
Hello all,
I recently rooted my Amazon Fire tablet - everything went fairly smoothly and I was able to make the standard changes (remove ads, change launcher, block OTA, etc). I tried to flash TWRP recovery but failed at every turn; fastboot gives me "unknown command" errors, and using Flashfire goes through the entire flashing process, reboots, but still no recovery. The issue I'm facing now is that it looks like the stock amazon recovery is now missing, when I try to boot into recovery using volume down+power it just hangs on the Amazon logo, holding down power to reboot it from there will boot it back into the OS just fine. I'd rather just have the stock amazon OS with it's recovery if it's not possible to have a custom recovery/ROM. Any suggestions? Thanks!

You can not install a custom recovery on this device (locked bootloader with no known exploits). Attempting to flash TWRP likely destroyed stock recovery. There is no fix. If still under warranty contact Amazon for an exchange.

After first boot with "corrupted stock recovery" (TWRP) system will try to restore stock recovery.
Try to power off tablet and boot into recovery one more time.
If it doesn't work you can flash stock recovery manually (need root).
For build stock recovery.img you need appropriate update-kindle-*.bin, another android device and some knowledge.
Or you can publish result of
Code:
@adb shell getprop ro.build.version.incremental
and i'll do it for you.

It will be great to see evidence this actually works on a 5th gen Fire. To date restoration of a borked stock recovery has proven elusive. I'd love to be wrong on this as there are a number of users who would benefit.

We talk about tablet that can boot into Fire OS, but not into recovery, aren't it?
But even with bricked tablet (5.1.1 after FlashFire error) it work.
AFTV tools + stock recovery + magic word.

Not interesting?
