Hey guys, I did something really stupid.

I acquired an Atrix HD through a third party, network/sim unlocked it to work on T-Mobile, and tried to flash 4.1.2 Mexican Retail (MB886_niimx-user-4.1.2-9.8.2Q-50_MB886_NII_TA-2-16-release-keys-NII-MX) through RSD Lite 6.1.5 after removing the getvar command and.. it failed half way. I forgot to unlock the bootloader before flashing.

Now I'm stuck and I've tried almost everything to fix it. I've searched Google and XDA, in the process I have downloaded Myth Tools, sirhoover_atrixhd_utility, motochopper, motopocalypse, and moto-fastboot, tried them all to the best of my knowledge and nothing is working. I've even edited the XML file to exclude the files it fails on.

Common errors I encounter:
Fastboot reason: Boot failure
Fastboot reason: Flash failure
Partition (boot) Security Version Downgraded
Preflash Validation Failed for boot
Partition (system) Security Version Downgraded
PIV black validation for system failed
Invalid PIV image: system

Worst part is, I can't unlock my bootloader because I need ADB to do so! Recovery will give me ADB but only to sideload (available on certain recoveries I've managed to flash). If you have any ideas or information that could assist me in getting my phone back to normal, whether that's unlocking the bootloader through fastboot or flashing a stock rom sucessfully, I would greatly appreciate it! :good:

You don't need a unlocked bootloader to flash firmware through rsd.. Try flashing the stock att back.

Thanks for your reply :)

I've tried flashing several stock firmwares already, I get preflash validation failed errors every time on boot.img and system.img

Here's the firmwares I have downloaded:
MB886_niimx-user-4.1.2-9.8.2Q-50_MB886_NII_TA-2-16-release-keys-NII-MX
MB886_bell-user-4.1.2-9.8.2Q-8_MB886_FFW-11-4-release-keys-BellMobility-CA
MB886_att-user-4.1.1-9.8.0Q-97_MB886_FFW-20-27-release-keys-ATT-US_BuildA
7.7.1Q-144_MB886_MR1-22_SIGNED_CFC
7.7.1Q-115_MB886_FFW-14_SIGNED_CFC

I wish I knew exactly the version I had before I started flashing, but unfortunately I do not..

Once your phone's OS has been upgraded, I don't think you can flash to an older firmware unless you have an unlocked bootloader. I'm not sure but that maybe the reason you're getting validation errors.

Did you try re-downloading the firmware?

Just tried re-downloading everything on a brand new Windows install on a different computer, still having problems.

No matter how hard I try, I cannot get boot.img or system.img to flash from any Stock firmware, whether it's AT&T, Mex, or Bell

Using snap-fastboot:

snap-fastboot flash boot boot.img
sending 'boot' (10240 KB)...
OKAY [ 0.788s]
writing 'boot'...
Preflash validation failed
FAILED (remote failure)

snap-fastboot flash system system.img
sending 'system' (30720 KB)...
OKAY [ 2.343s]
writing 'system'...
Preflash validation failed
FAILED (remote failure)

I'm going to try making a Motorola Factory cable in the meantime. Any other suggestions?

EDIT: Factory cable didn't help.. is there a way to generate a higher security version? No matter what, the bootloader always displays Partition (boot/system) Security Version Downgraded
I really don't want this to end up being a paperweight

I just got a new Atrix HD replacement and its showing firmware of 9.8.0Q-97_MB886_FFW-20 . Its not the same as the firmware available here: http://sbf.droid-developers.org/ .... I get the same error even after modifying the XML file in the SBF. Wonder if the last update caused an issue. Running into some similar issue with the replacement. Its not wanting to bootloader unlock.

Did you mount the system before installing?

Did you reboot each time you loaded a different set of fastboot files? Did you remove the previous fastboot files before installing a new set of fastboot files? Are you able to try this on a different computer?

That's exactly where I got my firmwares from. And to answer your question, I have tried this on different computers but I wasn't doing much rebooting when changing fastboot files.

Boot problem

Hello here I have a problem and I made everything from my knowledge but It's not fixed.
I have a Motorola Droid Maxx X8 verison XI1080, version 4.4.4, built number SU4.21,
If I install or do something and I switch off and I turn on my phone it disappears as if it is never done and if I try to reinitialize the phone I have a error Fastboot Reason: Boot Failure
If I get the fastboot and I take recovery its said Boot up failed.
I did everything I flashed with RSD and I update it with Motorola update but still nothing we see that the flashing and the update works but on reboot Its has no effect on the phone its stays as if you did nothing.
Please help me! I look forward to a solution, I thank you more.
