Hello,
I made a full TWRP backup and restored to another device. It seems that I also restored the EFS partition by mistake
Now, both of my devices have same mac address for wifi and bluetooth which is causing lot of issues for me. I tried to change the mac address using busybox but it doesn't seem to work.
Is there a way to edit the EFS file and modify the mac address ? I tried to edit using UltraEdit but I didn't found my mac address in it.
Any help would be very nice
(concerned device : Samung Galaxy Tab A 2019 10.1" with Nexus Rom)
OK, finally found it in the Ultra Edit. the mac addresses are splitted on 2 rows. youmust search for a partial mac address.

Hello how did you manage to extract your mac address from that efs1.emmc.win? (TWRP backup) I am failing

It occurred to me that there must be some kind of really easy solution to the problem of cracking a windows phone and applying Android and ending up with the WiFi MAC Address conflict issues...
I have 00:90:4c:c5:00:34, but my "real" MAC address ends in :38...
My guess is, there is a string in some bit of code, somewhere, a config file or a boot file, or some hardware file that has this MAC address in it.
Wouldn't it be easy to just go into that line in the code or config files and change it?
Or am I making this too simple?
Is this some kind of default address handed out when a program fails to find a proper MAC Address (nand not working, etc)?
I have searched all day for a solution, and tried 3 or 4 that I found without success.
So my questions are:
1) If this "default" MAC Address (00:34) is in a config or other file, what file would that be?
or
2) is there a simple way to change the MAC Address some other way, so I can get all 3 of these devices on the same network?
I have Android 2.2, Kernel 2.6.32.15r8.4-gb02a70d (hastarin... #66), Build 2.29.405.2 CL263770, Software Sergio Core Droid Desire V0.8...
On an HTC HD2.
(maybe there is a better distribution that gives me this same kind of look and feel that might work better for this problem?)
Thanks in advance for your consideration and help.

Look here http://android.stackexchange.com/qu...nge-permanent-mac-address-on-my-android-phone, you need to have root. Haven`t done this myself though. Good luck.
Please, tell us if you get WiFi working with a different MAC address.
I tried and I wasn't able to auth.
You can change your nexus 4 MAC address with a rooted device and the app called MAC Spoofer (root) (you can find it at google play)

I had the need to spoof my mac in my s4 when recently bought, because mac filter in my home´s wi-fi so i download mac spoofer apps from google play, none work then, but this works https://play.google.com/store/apps/details?id=com.wireless.macchanger, obviusly rooted and busybox installed,
for permantly mac addres change:
my address is 00:1A:73:XX:XX:XX in stock roms, in custom roms or stock with custom kernel the mac change into 84:38:38:XX:XX:XX, i thought that was a flashing bug, but turns out to be that custom kernels read the mac addres different from stock kernels, stock kernels read the info from these two files using root explorer /efs/wifi/.mac.info and efs/wifi/.mac.info.bak the mac addres is storage there and editig those files with root explorer to the same mac writen correctly, rember both and delete /efs/wifi/.mac.info and efs/wifi/.mac.info.bak.bak if created, and flash a STOCK rom with odin the mac address will change permantly unless an efs backup is restored or flashing a custom kernel.
try this at your own risk if needed, and always, always make an efs backup first i recomend efs back up pro in xda windows tool, this is high risk procedure and can mess your wifi,
Sorry for my english and good luck
Hi all,
*
To my work, I can access to the WIFI by giving my MAC address. I gave my MAC address, and ok, I had access.
However, I flashed the rom CloudyG3 and following this, no access to WIFI... I've realized that my MAC address had changed (and I saw I 'wasn't alone in this case) ... So I did a new request for an access with the new MAC address, and it doesn't work ...
*
I used the application Wireless mac address change to replace the current MAC address with my old address and I regain access to the corporate network ...
*
So is there anyone could help me to find my old MAC address? I tried to reflash my phone, it does not change ... I tried to pass on the Rom OptimusG3, the MAC address remains on the new ...
*
Thank you in advance for your help
Mine does the same thing and I cannot get a answer on how to fix the wifi mac address change.
Flash with my Nandroid backup... unsuccessfully...
This guide is for users who want to change their device mac address. Mac address blocking can be a problem in public WiFi. Where the administrator can block your access to the internet using a mac filter !
The mac spoof apps on the play store wont work with xperias
Mac address handling varies with OEMs. So the trick which works on other devices, wont work on Xperias
This guide supports all Xperia devices (Zl /Z /Z1 /Z2 /Z3) on the latest KITKAT version (4.4.4)
Step 1
Copy the follwing from / data / etc
wlan_macaddr0
wlan_macaddr1
wlan_macaddr2
wlan_macaddr3
Step 2
Paste these files at /system/etc/firmware/wlan
Step 3
There will be files such as
macaddr0
macaddr1
macaddr2
macaddr3
Now rename all the above files to some other name. Like "macaddr0p" and so on..
Step 4
At /system/etc/firmware/wlan
You need to rename the files you have already copied
wlan_macaddr0 to macaddr0
wlan_macaddr1 to macaddr1
wlan_macaddr2 to macaddr2
wlan_macaddr3 to macaddr3
Edit the above files using text editor to the preferable mac address you wish to have and then REBOOT !. This is permanently change your mac address
Be careful while editing the mac address. Use numerals and first few alphabets till " f ". Otherwise the mac adress will change to 01:00:00:00:00:00 and WiFi might not work.

Hi,
First of all thanks for the info
On which version of Android did you tested ? Is it the same for all flavours of Android ?
Can this method be used on other devices or just Xperias ?
