I should have said that fastboot is only available if you have the v8 unlocked bootloader

[Q] (soft)Bricked Atrix with no OS

I recently tried putting on a custom rom, and it seemed to too go smoothly until it rebooted and then had no OS on it.
It seems like a softbrick, but my computer won't recognize it when I plug it in with RSD mode, so I can't use ADB.
Could it be hard bricked? and if it is hard bricked will I just have to buy a new phone?
I also have an external sdcard if I might be able to load anything on that, to try and fix it.
if you just trying to load a custom rom, are you not able to boot into ClockWork Recovery?

The recovery I had disappeared along with the custom ROM, after it installed and rebooted.
When I turn it on it is just on the booting screen, I don't even get any errors, just nothingness, and with RSD my computer won't recognize it.
Can you enter recovery? On boot press volume down + power, then volume down until you see recovery, then volume up.

I can, but the "wipe data/factory reset" doesn't accomplish anything.
use fastboot to wipe it from a pc
that generally will wipe out a mess like that then place a good working rom on your sdcard (like darkside) and reflash
be sure to wipe data/cache and dalvic

What is flashing the ROM? I looked it up but under my recovery screen I only have "apply update from sdcard" would that be flashing?
I have tried putting a ROM on my sdcard and applying an update (I always do all the wiping) but got an error from signature verification.
Could this be because I need to format the sdcard with the ROM on it then insert it?
And I'll use that darkside rom it looks very interesting

Which recovery are you using?You should be using Romracers. If you arent, flash it via fastboot then try again.

Make sure you are running the most recent CWM (1.7.2 or 1.7.3)
Boot to recovery, and this time, do all your wipes
Wipes Menu
a. wipe Data/factory reset
b. wipe cache
c. wipe Dalvik
Go to Mounts and storage
a. Format system
b. Format Flexrom
Install rom, and make sure it's a rom with an ICS kernel.
As a last chance if the above normal things don;t work,
you may have corrupted data somewhere, and in this case, go to Backup and Restore and toggle Data Media. NOTE: This will wipe your tab clean of fotos, music, etc. Everything.
Then do your wipes and formats.

I have tried the suggested and I'm still on boot loader.
ROMS I used
FLEXREAPER-ReliX-GT_Rev1 ANDROID 4.0.3
RE-FLEXxx-ShellSHOCKRev1.1
Acer_AV041_A500_1.054.00_WW_GEN1-DEODEXED-FULLROOT
Also on CWM1.7.3 latest
Wiped everything twice and didn't see any change so should I try a stock Rom and just revert to non root ?
You can also wipe userdata from fastboot: "fastboot erase userdata". You may try using adb after a while and do logcat, from where you can see what's the issue.

I must have messed up but now I have gotten on fastboot mode but don't see the setting to erase userdata
you type in command from PC.
open cmd prompt from where u have fastboot.exe
type: fastboot devices
u should see a ?
then type: fastboot erase userdata
it should then tell u userdata erased.
u can also flash recovery.img with fastboot and get yr cpuid....very useful

You have to have the Android SDK installed on your PC.
Then you will find it in Program Files (or Program Files (x86))/Android/Android-SDK/Platform-Tools/ There you will find fastboot.exe

You probably got "java' is not recognized as an internal or external command."
You still need to install the Java dev kit. Go to Oracle, and get the Java Jdk7 and install it. (remember, android uses Java)
http://www.oracle.com/technetwork/java/javase/downloads/index.html
Then, after install, view this video to set the PATH, then do the same for CLASSPATH
http://www.youtube.com/watch?v=D13ZSPA1Ff0
You won't get that error anymore.

Okay I downloaded the java 7 and followed the process but still got errors so i went to sdk folder and did it over
I went by this video and it worked "http://www.youtube.com/watch?v=oaNM-lt_aHw"
After I got commands to work i typed fastboot erase userdata and i got on my tab "erasing uda partition then it said Done.
I used the cmd to reboot table to recovery and download a new ics rom.
It didnt work it went back to its ussal stuck on v8bootloader self. What do I do now ?
I'm in the exact same position right now. On ICS v8 bootloader, flashed latest re-flexxx rom, tablet was sluggish. Turned it off in order to restart it. Upon restart tablet froze @ "booting primary kernel." I tried everything I could as far as doing things in CWM (flashing different roms, none would get past booting primary kernel | tablet won't go into APX Mode) Tried flashing TWRP via CWM, now I can't even boot the recovery kernel.
Booted into fastboot, erased userdate. Sent fastboot flash recovery recovery.img (CWM). Said flashed SOS Partition successfully on tablet. Tried rebooting into recovery, same thing; freezes at booting primary kernel. I'm pretty sure this is the end of my A500 lol.

try twrp recovery. but cwm should work too. try booting recovery through fastboot..

If you have installed the new boot loader latest official CWM will not work unless you flash an unofficial version (6.0.1.5 if I remember well).

HELP! stuck in recovery [SOLVED!]

Issue solved by using the following commands in fastboot via this link http://forum.xda-developers.com/showpost.php?p=34552123&postcount=1, For anyone who has a similiar problem do the following.
1) Make sure your computer recognizes your device by typing: fastboot devices
2) Unlock your bootloader (if you have not already done so): fastboot oem unlock
3) You will see a prompt on your device. This will wipe your entire device (including the /sdcard folder). Accept. Note: you use the volume keys to change the option and the power button to accept. You cannot use the touch screen.
4) Reboot by typing: fastboot reboot-bootloader
5) Flash the bootloader: fastboot flash bootloader bootloader-mako-makoz10o.img (or whatever the name of the bootloader image that you downloaded).
6) Reboot: fastboot reboot-bootloader
7) Flash the radio: fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.48.img (or whatever the name is of the radio image that you downloaded).
8) Reboot: fastboot reboot-bootloader
9) Flash the system partition: fastboot flash system system.img

Flash recovery from fastboot using "fastboot flash recovery". Then you can use adb from the custom recovery.

Oh yes understood, unfortunely I can't..it's the part where you hook the battery. But now I have a new phone, I only need to know if there is a way to recover data without a battery plugged in, so a command in fastboot mode.

fastboot format userdata
fastboot format cache
fastboot -w
I'd then flash the factory image with fastboot. That way the partitions will be written to twice.
Edit, if you're able to use fastboot have you tried booting into a custom recovery?
