Fastboot Reason: Boot Failure

Hello dear friends!
I have a problem with my Atrix HD. I have problems to flash the boot.img and the system.img.
I tried with RSD Lite, Myth Tools - AHD, Fastboot flash and none have been able to flash it. I downloaded all drivers!
may be permanent brick?
The only thing I shows Battery Low, Battery OK sometimes.
I saw on some forums that the "Factory Cable" has the possibility to flash my phone.
What are the chances of coming back to life my MB886?
Here the details of what I show!
AP Fastboot Flash Mode (s)
10.9b (*) (sha-2e68372, 2012-11-17 23:33:08)
eMMC Info: Size 8GB
Device is LOCKED, Status code: 0
Low Battery
USB Connect
Data Cable
Partition (boot) Downgraded Security Version
Fastboot Reason: Boot Failure.
Waiting for your prompt help
Thank you.
Greetings!

nothing to panic... hold power+vol up+vol down to power your device off and put it to charge (do not charge with pc/laptop, use a AC power source)
after an hour, follow these steps..
1)download the required firmware from here and fastboot binaries
2)extract the zip and place downloaded fastboot binaries in the extracted directory and open terminal in this directory.
3)type the following commands in order
fastboot flash modem NON-HLOS.bin
fastboot flash boot boot.img
fastboot flash devtree device_tree.bin
fastboot flash system system.img
fastboot -w
fastboot erase cache
fastboot reboot

I saw that to unlock the bootloader need to be root, you got marked unknown sources. and that I can not do with the phone bricked.
Could you please send me a program or application with which I can do with the phone brick?

Go into power in settings and turn off fastboot if it's on. Also, you do have your bootloader unlocked , right?

Can't Flash Recovery

I'm on the T-Mobile variant and have followed the steps on the motorola website to unlock the bootloader. When I boot into fastboot, it says the device is unlocked with at status code 3. When I run 'fastboot flash recovery recovery.img' everything seems to run fine:
fastboot flash recovery recovery.img

finished. total time: 1.930s​When I try to reboot into recovery mode it just shows me the warning that my bootloader is unlocked, then boots as normal. I don't know what to do. I've tried both the twrp and cwm recovery images. Any help?

Yup. From reading around it seems like there's a script in /system that flashes the stock recovery upon booting up. I tried to get the PwnMyMoto apk onto my device to get root and remove the recovery script file but now I'm getting an unexpected exception when trying to install the apk through adb. I have both USB debugging and Unknown Sources allowed. Any ideas?
Edit:
By the way I am T-Mobile, post OTA. If that changes anything.

This might be a long way to do it but can't you downgrade back to 4.2.2 then get root with that then follow the instructions found in the general section for maintaining root through taking the ota? This should fix your problem. Also the instructions there might give you a different idea of how to work around this issue. You might just be able to flash the boot image and install the hidden su yourself.

I'm already on 4.2.2. I'm guessing you mean to undo the recent OTA? How would I do that without a custom recovery or root?

One more clarification: After you flash recovery, you are using the volume down key to highlight recovery and then you are using the up arrow to select it correct? You do not press the power button to make the selection as on nexus devices.

PS you had recovery the first time you hit the up volume and it sent you to a screen that said "no command" from that screen if you press the up volume and power button together it sends you to the recovery screen. It may be down volume and power together to get passed that "no command" screen but its one of the two. I saw people having that same problem in the forum about maintaining root through the OTA.

Will charge up a bit over 50% and see. I still get permission denied. Plus when I try to get into recovery, I can't. The Motorola log shows up for a while, then restarts and boots normally into Android.

i also have same poblem d415

me too...same problem D415 tmobile version

Does anyone with this problem have an lg d-415 and android with root? Because I think these commands in a terminal emulator or in an adb shell will fix fastboot:
Code:
su
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
Or if that doesn't work try this >> https://forum.xda-developers.com/lg...ick-hard-bricked-l90-variants-t3173429/page24
I think this problem is caused by people not unlocking the bootloader.

PLEASE HELP. I'm getting the same error on my LG D415. They said on the other thread that this variant comes with the bootloader already unlocked but whenever i try to enter a command (e.g fastboot flash laf laf.img) or pretty much every command I enter (except fastboot getvar all and fastboot devices), I get the same message FAILED (remote: unknown command). My android is now stuck on the T-mobile logo whenever I try to power it up and I can't flash because download mode has been replaced with fastboot.

Restore Stock Recovery - Amazon Fire 7 5th Gen (Ford)

IF YOU PLAN ON INSTALLING ANY CUSTOM ROM CHECK THAT YOUR RECOVERY IS ACCESSABLE!!!
If you have lost access to your stock recovery on your Amazon Fire 7 5th Gen (Ford) for whatever reason I would highly recommend restoring your recovery before doing any further customization to your device. Without recovery you have absolutely nothing to fall back on if your device becomes inoperable. If you have tried flashing any type of custom recovery directly to your device its more then likely you have lost access to your stock recovery. Hopefully youv made it to this thread before it was too late and luckily its a pretty simple process to restore your access.
Before we begin you must have a working OS for this process to work. If your device will not successfully boot then you can not complete the steps necessary to restore access to your recovery.
First lets
• Download Fire 7 Stock Recovery Image https://app.box.com/s/tjju5dptvsmsfjienf37siip8j6ch7wo
• Download and install the Flashfire App http://download.chainfire.eu/950/FlashFire/FlashFire-v0.30-20160331135212.apk
Next we'll
• Open the Flashfire App and allow it root access
• Press the red "+" button and select "Flash Firmware Package"
• Browse to the folder containing the Fire 7 Stock Recovery Image you previously downloaded and select it then press the "√" in the upper right corner
• Change Reboot option from "Normal" to "Recovery"
• Press the "FLASH" then "OK"
• Flashfire will reboot into recovery when its complete (Usually only takes a couple mins but its possible it may run for more)
It is also possible to restore access to recovery using Flashify

http://www.apkmirror.com/apk/christian-gollner/flashify/
• Press "Select Recovery Image" then choose file
• Browse to the Fire 7 Stock Recovery Image you downloaded earlier, select it and choose "Yup"

That's it now you're back in action!!!

Thought about that this morning as well. If no one else confirms before I get off work here shortly I will try then. (Especially like to see someone with a hard brick attempt it) In theory it seems it should work since the image seems to carry the signature from Amazon. Well at least that's what I picked up from researching for a fix to restore access to recovery on two of my fires.

Doesn't appear to work. My recovery randomly stopped working while I was trying to get SlimLP to install (unsuccessfully). Details Here
If I try to flash it:
sending 'recovery' (16384 KB)...
OKAY [ 0.474s]
writing 'recovery'...
FAILED (remote: Flashing not allowed)
finished. total time: 0.480s

If I try to boot to it, same error as if you try to boot to TWRP:
D:\Downloads\android-sdk-windows\platform-tools>fastboot boot fire7-stock-recovery.img
downloading 'boot.img'...
OKAY [ 0.531s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.535s

Took me a minute to realize I had to put "recovery" after flash, but even after I did, I sadly got the same result:

Now that flashfire allows us to restore backups from fastboot could we restore a back up of stock recovery or system to get flashfire bricked tablets working again?

Unfortunately I don't believe so. We need a key to unlock the actual ability to flash via Fastboot. As far as I know at least

I suspect that capability is coming (foundation is in v0.32) but probably not for this device due to fastboot restrictions I posed by Amazon.

Sorry cross posted removed
