It was tested with my CFW (GingerLF) but it should work with any CFW for Kyros 7024/8024/1024, like steev's AllDro2 CFW. 1. On your tablet, copy the file /system/wifi/softmac to /sdcard (internal microSD user space) or /extsd (external microSD) using a file manager or adb. 2. Rename it to mac.txt 3. Place mac.txt on the same microSD you use to install the new firmware in the root directory ("/"), the same place where you may see u-boot.bin or utscript If you have adb, you can do use this command to get mac.txt file on your computer: Code: adb pull /system/wifi/softmac mac.txt This will preserve your MAC address of your WiFi interface when installing a new firmware.
