General :: Error Fastboot Flash Recovery Due To Reboot

I have an AT&T Atrix 4G and I wanted to imstall CM7.2.

I had the latest Atrix Android version on it. Then I followed the instruction at the cyanogemod wiki for the atrix. So I flashed the sbf (cyanodenmod wiki -> Motorola_Atrix_4G:_Full_Update_Guide).

The rsd lite flashing didn't succeed because the atrix rebooted and the programm couldn't switch into BP passtrougth, or so. At this point the device said something about 0x1000 no bootloader, but I could choose between rsd, fastboot and the other possibilities.

I booted into the fastboot mode and did an oem unlock. Now it says unlocked.

I booted again into the fastboot mode, and now it should be a simple

Code:
fastboot flash recovery recover.img

But:
Windows) it always says:

Code:
sending 'recovery' (4824 KB)... OKAY [ 0.453s]
writing 'recovery'... FAILED (status read failed (Too many links))
after that the device reboots and is in a boot loop

so i tried linux) The first time i tried the command everythings worked fine, but after reboot i chose.

Code:
android recovery mode, but after a while (secs) the device rebooted.

so went to fastboot again, but now the device reboots after the sending command and then it says writing failed because of no device

I don't know if when I am using rsd lite to flash a complete image the phone reboots again and i have a hard brick.
