I AM NOT RESPONSIBLE FOR ANYTHING THAT HAPPENS TO YOUR PHONE, YOU OR TO ANYTHING THATS IN RELATION WITH THE PHONE OR YOU.
this tutorial will be for use with adb shell (if anyone wants to make a script or a batch or even cwm flashable out of it, be my guest, i dont really have the time and my knowledge is a tad limited in doing those things )
2.adb on your computer with at least some adb/linux terminal knowledge
3.rooted ATT Atrix (i tested it on mine thats from ATT and several others did too, dont know if anyone tried with the bell or other atrix's but im sure it should work)
4.some common sense
5. i assume you have am external sdcard aswell (if not swap the sdcard-ext for sdcard only to use the internal card)
TURN OFF WIFI in the settings/wireless networks menu 1.connect phone to computer with us on usb mass storage mode and without adb debugging, create a folder called wififix on your external sdcard, unzip and copy the three .bin files to that folder 2.do the safely remove on windows/linux and than change connection to none, disconnect usb, enable adb debugging and reconnect your phone to the usb 3. run cmd/terminal 4. write as follows, after each line press enter: adb shell su (allow su on your phones display if its the first time you are using adb with su) mount -o rw,remount -t ext3 /dev/block/mmcblk0p12 /system rm /system/etc/firmware/wifi/*.bin cp /sdcard-ext/wififix/*.bin /system/etc/firmware/wifi/ chown root /system/etc/firmware/wifi/*.bin chgrp root /system/etc/firmware/wifi/*.bin chmod 755 /system/etc/firmware/wifi/*.bin reboot 5. let your phone reboot, disconnect usb, unlock phone, enter pin, enable wifi and its working.
