Naturally i tried with alternative browser it's the same !! After this i tried to open manually the port used in question on the router.... Nada !! Reboot pc and phone also!! Any idea???

Wi-Fi MAC address changing

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...

Hello,
Is it possible on Samsung Galaxy SII GT-I9100 ?
thanks

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.

thanks ! I hope anyone will do this

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.
I'm using Karbonn A11(rooted).

You need a kernel that supports it.
BTW: Why on earth is this thread in the Q&A??

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 ?

Triying to use the TOR network. Orbot app

Hi all!
I'm trying to connect to the tor network with my SGR.
I was reading something about this in xda, but for the SGR didn´t find anything.
In the orbot official page, ( https://www.torproject.org/docs/android.html.en ) sais that with this app ( https://play.google.com/store/apps/details?id=org.torproject.android ) we can get access to the tor network.
We need a rooted phone, and a rom (in the page names the CyanogenMod rom ) that supports iptables.
Well, now I'm running the lastest version of Adam's CM 10.1 (4.2.2) and the app works (it says that I get connection to the tor network) But the router to this network fails. I can't use any internet connection.
I try to find something in other XDA forums (in SII forum there is something... but I didn't find my error, and nothing about it) but I only find that in Jelly roms, is needed a fix for work. I try it, but not working....
My question is. Is there anyone using this app? And if someone knows about it... please can help me?
Thanks to everybody!!
(sorry for my english...)

I used Orbot on GB and it worked like a charm. Just like SSHTunnel did. Since ICS, SSHTunnel is broken (I was sad to see this and had to find out how MAC address changing works. ), even in CM. Maybe this issue is related to that.

Thanks Adam for your answer.
With Orbot App I can use whatsapp and the Orweb browser only. But all other apps can't use the tor network.
Probably Adam you're right about the ICS problem with tunneling is rellated with this problema
Thanks!!!

p6800 problem flashing Slimrom, Carbon, AOSB from PacRom milestone.1.release
Hey Everyone,
Noob here, been using Daniel_HK's Pac Rom as a daily for almost a year now, happy happy, but now I wanted to try Slimrom, smaller footprint, easier on RAM, maybe. Problem is, I can't get latest Slimrom, Carbon, or AOSB to flash with either CWM-6.0.3.0 or CWM-6.0.4.5. Just wondering what kind of diagnostic information to provide and if anyone can offer me some help. I have experience with Odin (took a stock p1000 through Overcome and CM9) and have tried CWM flash and Mobile Odin on the P6800. I try Factory Reset/Wipe Cache/Wipe Dalvik, flash rom, and then try reboot, also try all Wipes, then reboot, try Format System as suggests in the Slimrom FAQ. Not sure what my next step is, really want to try Slimrom or Carbon or OMNI. Any help is greatly appreciated. Big thanks to Daniel_HK and everyone who keeps our beloved P6800 alive.

Bluetooth pan
Trying to get Internet connection on Galaxy Tab 7.7 P6800 from Iphone over bluetooth
In iPhone, there is blue stripe on top saying there is one device connected to modem
In P6800, there is "Used for internet connection of another device" status in Bluetooth Settings under the Iphone (not sure of exact status as it is in Rusian)
But there's no Internet on P6800 (e.g. browser says "no internet connection")
Device is Galaxy tab 7.7 P6800, slimkat Slim-4.4.4.build.8.20-UNOFICCIAL-20141215-1732
File bluetooth-patch2.zip installed (from here http://forum.xda-developers.com/showthread.php?t=2666261 )
From very same iphone, internet sharing over bluetooth works with sony z3 tablet without problems.
Files are transfered to P6800 from windows machine over bluetooth with no problems.
The question is if it is possible to connect to Internet from P6800 over bluetooth?
upd. Actually happens the following.
After connecting, I see in terminal window that interface bt-pan is up, but not ip address assigned to it
after performing commands in terminal with root rights
netcfg bt-pan dhcp
route add default gw 172.20.10.1 dev bt-pan
Internet is working in firefox and chrome browser (but not in embedded browser).
In play market, I can search for application but can not install it, as play market says "waiting for network connection".

Sony Xperia L,Cannot use WIFI [cm-12.1-20151103-NIGHTLY-taoshan]

hi all.
before the issue, i wanna thank for your answers.
I've an Xperia L and i've installed CM 12.1 since about 3 days; but unfortunately found that i can't use WIFI.
I searched and found some reasons pointing that the error might be for my country's region and Google (US) restriction, i'm living in IR Iran.
is there any other ways to fix this hell bug?? All i need from my device is WIFI...& i'm not gonna change the ROM again.

Hey, I'm not sure what your exact issue is but I will present you some possible solutions.
1. Was your wifi broken since you flashed CM12.1? If yes:
What stock version did you have before CM? If it wasn't 15.3.A.1.17 (or if you don't know), flash FTF of this version. Then flash CM12.1 again by flashing the kernel img and then the zip file.
2. Sometimes, the wifi just doesn't work because the wpa_suplicant.conf is broken. This file stores all the wifi passwords. Open the file manager and go to /data/misc/wifi and delete the file. You will lose your passwords, but your wifi will work! If you forgot your passwords, copy the file to another directory before deleting it.
I hope this can help you, please tell me if it did!

hi there and thanks for the answer,
well my case was absolutly the number 1.
i lost my WIFI just after flashing into CM12.1
bafore that i had the original update of 4.1.2 jelly bean android version.
i also had flashed the deice after installing cm 12 into the jelly bean using this tft file: C2105_15.0.A.2.17_Customized-CE.ftf
it was the original OS from factory on my device, the WIFI worked correctly and i could use that & tethering & hotSpot
but when i flashed again into cm 12.1 i lost the WIFI & hotSpot again :|
note:i flashed the device using thunderzup kernel. could it be the cause of problem?
i'm still using the cm 12.1 & it's good.but the wifi problem.
i've the following bugs:
-WIFI can't be turned on in anyways
-the notification light doesn't work correctly sometimes
-the LED light can't be switched off from the notification bar once i switch it on,from that area.

As i know the ThunderZap kernel for Xperia L should get your WiFi work..
Try Zapdos kernel/stock kernel for xperia l.
i'm on Stryflex lollipop 5.1.1 Rom (CM 12.1 based). i don't have a wifi problem.
Use Light Flow Lite - LED Control from play store for customize LED notification.
