Hi,
yesterday i tried nearly the whole day to change my mac address on my x1. first i made a hardspl for x1. the new bootloader is working.
After that, i connected via mtty. I tried some commands like emapiTest, emapiWlanMac and some other what i found at xda-dev. I only go "command error" in mtty.
Then i flashed the latest rom (R2A) and tried it again with mtty. Same bad results.
There is a posting at xda-dev: NOTE: To use rbmc you need to
authenticate with proper password .... otherwise bootloader returns "Command error !!!" or "Command is Locked!". (if you're using Hard-SPL, this is unlocked, and any address can be read with 2.30.Olipro)
Do i make the same authenticate with the X1 HardSpl that i am able to work with any commands?
Best regards
strohrum
You can't change the MAC address of a network device. It's the unique hardware serial number of the network device.
My guess is that you're trying to get your Xperia to connect to a hotspot that only allows specific MAC addresses. In that case it makes more sense to find the wifi MAC address of your phone, go into the configuration page for your wifi router and enter the MAC address on the filter list.
You can get the phone's wifi MAC fairly easily. Turn on wifi, then:
Start > Settings > Connections > Wireless LAN > Advanced
... and the MAC is there for you.

Actually it is possible to "spoof" a network device.
I'm just not sure how to do this on a WM device.
i tried the registry method... didnt find any data for mac address
and i tried what jockyw wrote:
"You can run or flash the USPL (see sticky) and set a MAC address of your own choice.
Connect with MTTY and at the command prompt type:
emapiWlanMac 01 02 03 04 05 06 (the six two-digit numbers are the hexadecimal MAC byte values and should be replaced by anything you like)"
but i only get "command error" at any command.

Maybe you are right and xda-devs wouldn't care about that...

That is not legal I am sure.
Legal WHERE? 50% of the content here is probably not koscher! What a stupid question!
ANY medling with software is illegal worldwide! Read the license agreements!
I would suggest NOT to discuss this...waste of time and effort! Just a thought ;-)
why should be illegal to change mac address? It's not IMEI

Well, its not illegal in the "go to jail" sense... but more of a torts way. SE won't care that a relatively small group is tinkering with their own phones since it doesn't affect their income at all. Rather, if we filed a warranty claim, they can deny it on breach of terms.
The only time a modified MAC could be considered "illegal" is if you are pirating as a result of modifying it.
Why would you even want to change the mac-adress?

Please don't assume that something is illegal simply because it's "sometimes" associated with "hacking". Password recovery is not illegal, port scanning is not illegal, packet sniffing is not illegal. These are all used by most large companies on a regular basis. I'm a network engineer and I can assure you that it is legal to "spoof" your mac address. Even though there may be some unethical reasons for doing this, there are also unethical reasons for owning a kitchen knife. We change our mac addresses of many of the devices at work all the time for many, very legitimate reasons.
While there's no easy way to change the actual information stored in the CIS of a device, depending on the NIC driver, many drivers support dynamic mac addresses. Even Microsoft provides support for configurable mac addresses.
I dug around in the registry a bit and it doesn't seem like there is a default setting for this on Xperia (well, that I could find), but I'm sure there's a way to change the NDIS miniport drivers to simply call a new string value containing whatever you're trying to change your mac to.
Check out these MSDN articles that might help with a solution.

hi jhoffa,
thanks for the solution links. but i already need help:
At MSDN:
Finally, if the card information structure (CIS) of the PC Card contains a network address value, Ndis.dll creates a \HKEY_LOCAL_MACHINE\Comm\Miniport Instance\Parms\NetworkAddress key to store the network address.
My registry dosent show the path ...\NetworkAddress
\HKEY_LOCAL_MACHINE\Comm\TNETW12511
DisplayName
IEEE 802.11b/g Compatible Wi-Fi Adapter
At: HKEY_LOCAL_MACHINE\Comm\TNETW12511\Parms\TcpIp it shows me: Autocgf, autointerval, automask, autoseed, autosubnet, dhcpdns, dhcpipaddress, dhcpserver, dhcpsubnetmask, enabledhcp, lease, leaseobtainedhigh, leaseobtainedlow, prevreqoptions, t1 and t2. but nothing like a mac address.
is it possible that i am looking the wrong way?
thanks for helping

Have you tried adding
Network Adress as a (i'm presuming) a Dword to \HKEY_LOCAL_MACHINE\Comm\TNETW12511\Parms\ ?
i added "NetworkAddress" as String and typed a 12 letter mac in it. didnt work. Dword same.

i skiped this as i read your posting before. i know that i cant handle this, i am too noobish in registry files edit.
maybe someone could help me with that?
thanks

i found that at eggheadcafe.com:
Step 1 --> changes to driver
Steps [2-5] from C# application
1) In NDIS Intermediate driver (QueryMiniport function), I made the
following changes
a) When OID is CURRENT_MAC_ADDRESS , open registry , read a
registry name ChangeMAC,
b) if value of ChangeMAC is 1 then read registry value of "NewMAC"
and then convert it appropriately to MAC format
(remove extra unicode characters etc)
c) then do a NDISMoveMemory to current adapters MACaddr field.
d) close registry
2) Set value of ChangeMAC (DWord) to 1
3) Set value of NewMAC (string) to the new mac address
4) Invoke a NDIS_REBIND_ADAPTER (this internally will call
QueryMiniport ) and inturn execute step (1)
5) Set value of ChangeMAC (DWord) to 0
anybody an idea how does it work?

Using an unofficial program "stealed" from other phone or cook a personal ROM is not paragonable as change MAC Address.
MAC Address changes are the same of IMEI's ones: if you want to create-problems to a WiFi network (for example) with your modified MAC Address, you are not more identificable...so this is illegal.
To prevent the possibility of this type of "problems", all changes acts to alterate UNIQUE IDENTIFICATION of a device (IMEI or MAC Address numbers) are illegal, because it will cause a POSSIBLE multi-identity.
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.
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.
I'm using windows phone 8.1 lumia 1320 models. Wifi How do I need to change the mac address
To the best of my knowledge, you don't. That's not a thing you're even *supposed* to be able to do; there's basically no legit use for it except for certain types of security testing, and if that was your goal you bought entirely the wrong phone for the purpose. It might be possible - I've never tried - on an interop-unlocked phone, but unless Nokia is including very odd features in their OEM applications you're out of luck.
You could try running your requests through a PC (use a proxy server or set up the PC as a WiFi hotspot) and use the various driver tricks to change the MAC address on the PC, I guess?
You can't...it is saved into the rom of your wireless card of your phone. It is impossible with every device in the world
No, I could not tell you exactly. I want to change the mac address so fake. Previously I was using android and "wifi mac address changer" There was an application named. I currently do not have such an application in Windows phones.
I'm guessing that app required a rooted phone? Not (yet) possible on WP8.
Well, it works for me. What I needed was a Interop-Unlocked device (Lumia 520 for me), and an app named CustomPFD. Then, I went to this key path (0004 in my case), added a key (bc its not there), and added a String value.
Key Path:
Code:
HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\0004
Key Name:
NetworkAddress
Key Value:
AABBCCDDEEFF
(Output in about phone after reboot:
AA-BB-CC-DD-EE-FF)
Easy as pie, well not really.
You have to find the correct registry subkey containing your Lumia phone's Qualcomm Wireless Adapter (anything related to it, I guess).
Btw, if u want to reset your MAC address to default, u can just delete the key (NetworkAddress).
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
