Atrix reboot at start up screen after flash rom
I just buy an Atrix, version 4.0.4 Cyanogen, and I want to flash it come back stock rom 2.3 so I did following this guide:
Download the stock system image for the Motorola Atrix 4G (Gingerbread, firmware version 4.5.91)
Download the Fastboot ZIP package
Motorola Atrix 4G
Download the following files listed above and extract their contents into a folder on your computer.
Enable USB Debugging on your device by heading to “Settings > Applications > Development > USB Debugging”. Make sure that there is a check mark on the USB Debugging option.
Turn off your device and boot into Fastboot mode by pressing and holding down the Volume Down button and pressing the Power key.
Once inside Fastboot mode, connect your device to your computer via USB cable.
After connecting your device, launch a command prompt on your computer.
Change directory to where you extracted the downloaded files.
Type the following commands below and press the Enter key after each line:
moto-fastboot flash boot boot.img
moto-fastboot flash system system.img
Once the last command has been entered, your device should reboot.
Check whether or not you have successfully flashed the stock firmware by heading to “Settings > About Phone > Firmware Version” where it should show the current firmware version as 4.5.91. If there is another version except the one mentioned, then you need to redo the steps.
And now, my atrix start up...reboot...start up..
