Iam not responsable for damage on your cellphone...read each step before doing the whole process

NOTE i did the whole process on windows XP havent tested on windows 7 but it should be the same just make sure you have all you need and phone its detected with any problem by win7

1st i tried to go back to stock rom by normal ways if you made a backup with Clockworkmod you should try 1st..to restore that backup for that...you gonna do the step 5 and come back here again for extra step

extra steps

x. after cleaning all..go to the option of backup and restore...select restore..and then select SD and select the last backup you made that you know was on 2.3.4 select that folder and press YES INSTALL after finish..reboot your phone if your phone doesnt boot like it should and start a bucle in booting logo ..means you are like i were..when i tried.. i did the step 5 again and did the other steps with SBF 4.5.141 wich was my version before i installed Cm7.2 and boilaaa..xD worked..

1. charged the phone to 100% (very important)

2. downloaded the lastest driver for atrix 4g --5.5 motohelper it says

motorola.com/Support/US-EN/Support-Homepage/Software_and_Drivers/USB-and-PC-Charging-Drivers

3. download the files for 2.3.4 ginger bread 4.5.91 here thanks to 1KDS ---> goo.gl/GEizI extract it anywhere just make sure you know where its..

goo.gl/YMS0j for people with the same version as me.. 4.5.141 GB 2.3.6 WORKED FOR ME

4. get RSDlite 5.7 from here ----> xdaforums.com/attachment.php?attachmentid=920654&d=1330265840 thanks to alsitn for posting the link

4. get fastboot files... mediafire.com/?j1qs6a75z3fv681 -uploaded by me-

create a folder at C:\ called Fastboot and extract the files in there (just in case you dont have fastboot files anymore)

5. do a full wipe with the following steps

a. enter recovery mode of clockworkmod

b. Wipe Dalvik (advanced option in main menu)

wipe cache

factory reset/data

c. turn off the phone and then enter fastbootmode turning ON the phone and holding VOL down and then pressing VOL up it should say starting fastboot protocols..then connect the phone to PC

d. on CMD (command prompt) navigate to the folder created on step 3** using CD.. to go back and CD "folder name" to go foward, when you get inside the folder where the files are..then write the following commands

fastboot erase boot

fastboot erase system

fastboot erase userdata

fastboot erase cache

fastboot erase webtop

fastboot erase preinstall

Disconnect phone from PC

6. then turn off the phone by removing the battery..then remove SIM and SD card

turn ON the phone holding VOL up it should say Starting RSD protocols.. run the RSDlite...connect your phone...make sure RSD detects your phone it should Say on model: NS flash olympus and just in the right column it should say connected.. after that... press the "...." button next to the textbox called Filename and select the SBF file you downloaded and extracted.. it should be 1.46 gb both files size are the same..so make sure your selecting the one you need (version you had before installing cyanogenmod)

7. after you select your file...press start it gonna takes around 25 or 30mins.. never disconnect your phone during the process it will reach 100% like 2 or 3 times and reboot phone 2 or 3 times too..... feel free to disconnect ONLY when the RSDlite says PASSED or PASS something like that..in the result column

8. after that you should be back to stock without ROOT without bootloaded unlocked:D ready for rooting and BL unlocking wich i like more..only to have that on my stock rom..
