![]() ![]() If none of these solutions worked for you, it very well likely could be a hardware problem – perhaps your WiFi antenna has become loose from the motherboard and needs to be soldered back on, or some related problem like that. ![]() Replace with first word from each lines 7. Replace comma separated list with string list 5. Insert a newline for every line of text 3. Removing arbitrary whitespaces and tabs 2. Add your MAC address inside this file, save it, and restart your device. Shortcuts to examples covered in this Notepad++ regex tutorial are as follows: 1. The last step to try is to use a root file explorer to look inside persist/wifi/.macaddr and open. Now type ‘ adb reboot’ and after your phone restarts, check if the MAC address is okay. Now we’re going to push it back to your device through ADB, so type into ADB terminal:Īdb push misc.img /sdcard/misc_edited.imgĪdb shell “su -c ‘dd if=/sdcard/misc_edited.img of=/dev/block/bootdevice/by-name/misc'” Open it with the hex editor software of your choice.įind the hex offset 3000, and edit hex offsets 3000 to 3005 with your wifi MAC address – “00 90 3D F1 A2 31″ for example. Now you should be able to find misc.img in your ADB root folder. ![]() If it displays a unique ID for your device, continue.Īdb shell “su -c ‘dd if=/dev/block/bootdevice/by-name/misc of=/sdcard/misc.img'” With your phone connected to your PC, verify that ADB detects the USB connection by typing ‘ adb devices’. I use Notepad++ with hex editor plugin, but other hex editor software should be fine. In any case, once you have ADB running on your PC, you should also grab a hex editor. To continue troubleshooting, you should have ADB installed on your computer – please see “ How to Install ADB on Windows” – Mac / Linux users have a far easier method that do not require a guide. There are several reasons why the MAC address may be corrupted, so we will try to address each one until your issue is resolved. ![]() If that did not work, we will need to get a bit more technical, so follow me closely. ![]()
