How to spoof captivate MAC address? - Captivate Q&A, Help & Troubleshooting

Does anyone know how to spoof the MAC address on a Captivate. I can't seem to find the nvram.txt file anywhere, or if there is another way I would appreciate it. Thanks.

Why would you?

Cuz im testing my network at home, and I want to see if it shows my new MAC address.

Only thing I can think of is enabling mock locations in development, but i'm not sure if that involves MAC addresses.

I am also having a hard time looking for the Mac Address? Any help from anyone?
This was a feature left out of Phone7 by Windows. The only way I can think of to obtain it is, if you're running Windows 7 and can make a virtual access point using Connectify to grab the Mac address once it connects to your computer

Yes it was confirmed also to me by HTC support that there is no way to look the mac address on the phone itself. The only way is to check the router's attached devices and check the mac address from there. I have to turn off the access control first of my Netgear router so that the HD7 will be able to connect to it.

Can't you then grab the Mac from the attached devices list and then apply it to your filter?

Good idea. Worked like a charm.
Here is an example of how to find it in a corporate environment. The following assumes you have access to the windows server that hands out DHCP addresses, assuming your wireless router does not. If your wireless router does, you should just be able to look it up in the DHCP client table of your device.
Anyhow...
I connect my HD7 to the wireless network, and the IP is supplied by the windows server. In the windows server, I go to DHCP and then Address Leases. I sort by expired date, and my device will be listed with the latest date, as it is the most recently connected device. I take note of the IP.
Then open a command prompt and type ARP -A
This will list the IP and MAC of all connected devices. Find your IP and there is your MAC.
The problem with my phone is that when I reboot it the mac address changes. My router works with a mac address filter. So I have to add a new mac address after each WP7 reboot.
Is there anyone with a solution?
If you unlock your device and install the Advance Configuration Tool the app shows you Mac address and other device details.

Solution: buy an HD7.

Are you sure? MAC address is strictly individual for each network adapter (ether or wlan).

I know that, but I think the wifi mac address used is a virtual one.
Yes I'm sure, the six last digits of my wifi mac address change, so I have to disable the mac address filter in my box, connect the phone, look in the box config which mac address is connected, add the new address to the authorized ones and turn on the address filter.
If you have a HD2 verify what I'm saying and you'll see I tell the truth.
cheap66, i have HD7 phone. My MAC Address is static. I use phone in my Uni. Administrators here use mac address filter too. I have no problems with that :|
He doesn't have an HD7.
In fact my phone is an HD2 and I think it's the reason why.

Problem with mac address

Anyone know how to edit or force android to read the mac address of the phone?
Because my brother has a optimus black like me with rom Macay and i have cyanogemmod and we both have the same mac address.
comands like: ip link set..... our ifconfig....
don´t work.
and the software don´t work:
Wireless Mac Changer
The mac addres is associated with your net adapter, meaning its (or should be) unique and exclusive.
In theory, two devices cant have the same mac address. Furthermore, in most countries, its illegal to change the mac of a device, and it must be done by modding the hardware.
Are you sure your router isnt giving the same IP to both phones? That could be a possible error.
It is easy to change it:
Search nvram.txt (should be in /etc/wifi/ or something) and set permissions that you can edit it. Edit "macaddr=XX:XX:XX:XX:XX:XX" as you want and save. After it set permissions to default (note down before edit) and reboot. Done!

[GUIDE] Wi-Fi MAC address changing

Hello everybody!
This is my first contribution for the O4X community. Hope you like it!
I have managed to change the Wi-Fi MAC address of my device and now I share this technique with you.
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 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 '/data/misc/wifi/config_mac'. This is done at a very early stage at bootup, I didn't check when, probably in native binaries or somewhere at the framework (though I doubt the latter). 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. So what you have to do is editing the '/data/misc/wifi/config_mac' file with a modified address.
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).
- If you delete the file or use an invalid one (e.g. 000000000000, ffffffffffff or 133713371337), Wi-Fi will stuck at turning on and you need to do a reboot to get it working again.
- Since the file is created everytime again at boot, it is not persistent. If you reboot, it is gone. If you would like to use it permanently, create a script (like 'echo "001122334455" > /data/misc/wifi/config_mac') with some script manager application and set it to run at each reboot.
I did not test this on CM. Since CM has the Wi-Fi module built into the kernel (Anybody knows why??), it may not work. Somebody pls try and report.
Every custom modification to devices have risks. Use this at your own risk!
Have fun and enjoy!
Hi, thanks for the support
I would like to say that I have managed to change the mac adress on the Cyanogenmod (cm10.1) by editing a file called "bcmdhd.cal", which is located in system/etc/wifi; the line is for example
macaddr=00:90:4c:c5:12:38
Click to expand...
Click to collapse
I only change the "38" with "39".
I have to edit it before installing the rom (every time I install the rom, I must say ), because my sister has another 4X, and with the same mac adress the router goes crazy
Thanks for pointing it out. :good:
Does the bcmdhd.cal editing change the MAC persistently? I assume it does.

yes, i change it in the zip, then after the install the wifi menu reports the new adress.
EDIT.... i found that my trick worked on the first nightlies of the cm10.1; your way does work on the stable cyanogen and last nightly
sorry for my english...
I just use MAC Address Ghost from the play store

I know this is an old thread, but this post of yours just solved a problem I've been having for months.

How can I change my Mac Address? (REDMI 8)

Everytime I used any mac address changer it just revert back to normal/can't change. Does someone know to change it?
1) I don't know if there is a way, you can Google it
2) why would you even want that??

MAC address = Media Access Control address
Kind of physical address of your device.
This unique address is given by the manufacturer who got a special address range/area from the IEEE (Institute of Electrical and Electronics Engineers).
So it is something a user should not be able to change.
Maybe you mixed it up with a different type of address
