Sorry, but you are looking for something that is not here.
Do you know where can i find it?
Not working with my chinese device
tried and failed with it.....any solution ?????
I checked few more posts about wpa_supplicant. It looks like the generic or posted files works on some device models. May be It depends on device configuration as well. wpa_config is associated file which may also need some change relavant to the wpa_supplicant or need modification for specific device models.
I am dont understand the code fully. I hope someone will sort it out
it's working on samsung galaxy s and many htc phones with
2.1 / 2.2 / 2.2.1 ( some 2.3.3 also if )
Hello everybody!
I have managed to change the Wi-Fi MAC address of my device and now I share this technique with you. With this method, you can change your address permanently!
What is a MAC address?
A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. It may also be known as a burned-in address, an Ethernet hardware address (EHA), hardware address or physical address. (Source: Wikipedia)
Why would somebody change his/her MAC address?
- To access the internet where it is restricted to particular addresses.
- To hide his/her illegal activity. (Though this is not effective enough since the Android system sends product information and a lot of other things to the Google servers and I'm sure that previous IP addresses could be searched for if somebody does something really nasty.)
Is it legal to change the MAC address?
As far as I know, it is. However, I firmly discourage you on doing anything illegal with changed/unchanged MAC.
Let's do it!
What do you need?
- A rooted device.
- A kernel with MAC address changing support. (I include my ICS kernel (version 3.1.10) for those who want to try it out and the method of implementing it into other custom kernels.)
- A file manager that can explore the root filesystem.
How does this exactly work?
Normally, the Wi-Fi driver gets the MAC address from the built-in chip then it writes the address to '/efs/wifi/.mac.info' and '/data/.mac.info'. This is the original burned-in address. This cannot be changed with software modifications, but only by soldering off the chip from the motherboard and rewriting its contents. Our Wi-Fi device is a Broadcom BCM4330. It has very good built-in features and the open source driver can be found in our kernel sources.
There are two different options in the driver (READ_MACADDR and RDWR_MACADDR (actually, there is a WRITE_MACADDR option too, which stands for creating the two files I have mentioned before)), which enable us changing the address. I tested both and found READ_MACADDR better. By enabling it in the kernel, you get some options regarding MAC changing.
Before you change your MAC address in any way, turn off Wi-Fi! I recommend writing down your original address somewhere (just to be extra secured). You can always return to your original one using the second method (read further) or by flashing a kernel that doesn't have the patch.
- If you flash a patched kernel and delete the '/efs/wifi/.mac.info' file, the driver will generate (!!) a custom MAC address based on some predefined rules (The first 24 bits are common in all generated addresses.).
- Of course you can set your own custom MAC address. Do this by editing the '/efs/wifi/.mac.info' file with a file manager. If you change it to an incorrect address, the system will automatically use the original (burned-in) MAC.
For kernel developers who want to enable this:
Find '#define WRITE_MACADDR' after '#ifdef CONFIG_MACH_N1' in 'drivers/net/wireless/bcmdhd/src/dhd/sys/dhd_sec_feature.h' and insert '#define READ_MACADDR' after that line. This is for ICS kernels (version 3.1.10), but the patch must work on GB ones too. You just have to insert the define somewhere else (I didn't look into this.).
(I count on you guys in implementing this! )
I attach my prebuilt (secure, MMC_ERASE_CAP disabled) kernel for trying out this feature. It is an ICS kernel (version 3.1.10).
Every custom modification to devices have risks. Use this at your own risk!
Have fun and enjoy!
Thanks!
Just tried patching the kernel, it works! So, this feature will be included in my next kernel.
Before flashing the patched kernel, when I turn off wifi, delete .mac.info file, re-enable wifi, the MAC address is not changed.
However, after flashing the patched kernel, after I turn off wifi, delete .mac.info file and re-enable wifi, the MAC address is changed!
Thanks very much for the useful guideline from Adam77Root :good:
Hey bro can u explain this in a more simpler manner...I'm a newbie here and i need this! bcuz my brother alwayz blocks my wifi mac address so i cannot access wifi. I hav a rooted Samsung galaxy ace s5830 using cm 10.1 rc4......thanks in advance!:good:

If kernel supports only we change the WIFI MAC Address, we can not use it on all the kernels...

Just have taken a look into your kernel sources and it seems it is.
Check this thread: http://forum.xda-developers.com/showthread.php?p=37299543
Somebody will surely compile a kernel for you.

I have looked into the sources of your Wi-Fi driver (the same BCMDHD) and it seems it doesn't support it. Maybe this is a Samsung-only feature.
any suggestion...?

I think your best bet would be the galaxy ace forums. You could search if there's an existing kernel with this functionality or else you could direct one of the kernel developers there to have a look at this thread.
I'm a beginner, plz explain in detail such that I can do it.

Hello experts,
since a long time I'm trying to fix my mutating MAC on a Huawei U8860 (so called Honor).
Your Thread gives me new hope. Atm I'm running a custom rom (baidu v.5, ROM 43) on my device.
Do you think, it's possible to insert the phrase into the kernel-source to make the MAC fix again? The wlan-chip is nearly the same as in your tested device (bcm4329).
What else do I have to patch? Is it necessary to write the MAC (seen on the label under battery) into any config-file?
I apprecheate your help - thanx for reading...
Works on Samsung S4 mini with CM 11, however I need to reboot after changing .mac.cob even when deleting .mac.info (which does not automaticly returns), as turning off/on WiFi isn't enough.
I guess the READ_MACADDR option is missing, and at one point I'd like to make my own CM modification. Or is there a more simple solution?
I'm new here..
I have rooted my galaxy note 2 gt-N7100
I want to change my mac address to another one that i want
Can you tell me how can I do it?
Hi,
Just over a year ago, I asked you a solution for my Galaxy S2, and you found me a solution thanks to this post on the Galaxy S2 forum.
Is there a similar kernel for Galaxy S4 GT-I9505 ?
Hello.
I have a problem ..... ¬_¬ obvious ... I made a backup of the phone with droidtools, but I did not create the "user data.img", "cache.img", "system.img" files .
And now I can not restore my phone. :crying::crying::crying:
And I've searched a lot, but there is no rom for my phone.
Is there any way to fix this?
Thanks in advance :good:
Note: Translated from Spanish by Google .....
Hola,
Bienvenidos a XDA.
If you were still on stock when you created your backup and you want stock back you can reflash your stock firmware via PC with whatever flashtool is compatible with your device. If you post your device model number I can at least get you pointed in the right direction to finding your answer.

Unfortunately, I am not finding any ROMs for you on XDA. You'll have to find your stock firmware by doing a google search using your device's model number, find it, get it downloaded and flash it from PC with whatever flashtool is for your device.
You can try posting in the forum linked below.

Good luck.

The tools you use will depend on your device, generally, Linux can be used for manipulating things like that on all android devices but the tools to make use of what you put together in Linux will depend on your device. How to use Linux to package things correctly for your device would be better answered by those that have your device, I am not familiar with your device so those kinds of things I couldn't tell you.
You should post your question in the link I gave you, the members there may have more answers for you than I do. There are too many kinds of android devices out there to learn them all, its best to find those that have learned that device.

Hey, my device is not supported and i would like to see it get supported, how can i help making it compatible
I have a oneplus one with cm13 (android 6.0.1, se linux enforced)
Edit: i found the file where the MAC address is found and the lines
I only need to check if 5ghz uses a different MAC because there are 4 MAC addresses / interface configurations pressent but i already know one of them as it matched the one in the WiFi settings
/persist/WCNSS_qcom_cfg Intf0MacAddress=C0EEFB43FAxx (removed last 2 hex characters) this is 1 of the 4 addresses present that us sure te be one of them
Edit2; if i have time tomorrow i might look into making a pull request
I have an Xperia L with Resurrection Remix (a CM13-based ROM). Unfortunately not supported

This would be immense help! Please check my newly created guide to implementing support here - you will save yourself a lot of time. If you can't make it work or don't have time, please let me know and I will implement it ASAP. If that's the case, please make sure you send me this info first.
Also, I never thought about 2.4GHz and 5GHz having a different MAC. Please let me know if you find they are different because currently I change only one of them on the Nexus 5X! Thanks!

HI there
i was tempted to flash miui8 custom rom by its look. every thing was fine except wifi and bluetooth i decided to go back to stock rom problem was not solved
i did research on it and finally got some conclusions and i am not able do decide which one is right.
1.My phone wifi mac adress is unavailable
2.I cant find any network interface related to my wifi like (wlan0,eth0) when i used "ip link show"
3.i checked kernel message by cat /proc/kmsg it shows that my wcnss drivers are not ready while i turn on wifi
4.and i heard that in root directory efs folder should be there which contains mac adress and all that stuff and in my mobile i cant
able to find it
And i believed that it was rom problem and flashed a new rom (cm 14) then i got my wifi and bluetooth in work:fingers-crossed::fingers-crossed::fingers-crossed:
but i was willing to know reason behind it and use my favorite miui8 rom
here are some useful information regarding to my variant
variant: lenovo vibe k5 plus
recovery:TWRP 3.0.2-r3
i downloaded rom from :https://forum.xda-developers.com/android/development/rom-miui-8-vibe-k5-plus-t3500400
