Hello
Can someone maybe help me with my problem ?
After i changed my mac address to 02:xx:xx my wifi doesn't turn on anymore and i have also no possibilities to change it again...
Phone: Red Magic 5G
Build: EN Common V8.11
Root: Yes (Magisk)
Android 10/Q
Any idea is welcome ! ^^
Best Regards
Akizuma
Have really no one the same problem ?
Or maybe a backup from a Red Magic 5G that still works ?
Why did you change your MAC address ?
You do NOT need to change your MAC address in Android 10, because you can choose for use a random MAC due privacy issues.
Your MAC address is shown only to system apps, all other apps, can NOT see your MAC address.
Android 10 masks your MAC address to 02:00:00:00 if any user app try to read MAC address.
Try my app and you can see it: https://forum.xda-developers.com/t/...ackage-com-vitaodoidao-vdinformacoes.4097379/
The problem is i can't start my wifi anymore or change it its not possible
And the next problem that i got is that i broke my persist folder so i have no possibilty anymore to see my screen (i need a original backup from a Red Magic 5G...)
I broke way to many things.....
Firstly, how did you change your MAC address ?
With a app from the google play store.
I started it and then pressed hard change.
After the restart my wifi was broken.
Then i tried with
Busybox to change it again but the wifi card doesnt show up so i looked up in the root explorer for the file where my mac was saved and i found it (it was wlan_mac.bin) the only problem i can't change it not even after i got all permission. (After many hour of tries i decides to delete it) but it still comes back with the same mac adresse.
So i decide to delete the folder and that was the moment where i dont get any screen signal from my phone anymore looks like in persist are files for calibration screen etc)
I'm really desperate right now, I don't know what to do.
Don't create multiple replies, if you need, edit your last reply.
Does this app was designed for Android 10 ?
Obviously, not.
Because Android 10 will never allow the user to change MAC address.
Your MAC resides in your NVRAM and NVDATA.
Once you format your data, your NVDATA is formatted and a new one is created.
And then, the NVRAM is copied again to NVDATA.
So, erasing NVDATA should fix your MAC.
(I've said to erasing NVDATA and not NVRAM. If you lost your NVRAM, you lost your MAC and IMEI forever.)
Probably, you need to wipe your data too, I'm not sure, so I suggest you to make backup first.
Good luck.

trying to find out what my phones mac address was before i sent it in for repair.
problem is my router/modem was replaced by bell since then, so i can't use that.
i do however have a backup of bml1-9, as well as my nv_data files from the efs partition and some z7logs, but haven't had any luck searching through those.
thanks
Settings => About phone => Status => Wi-Fi MAC address
Update: I just realize you have already sent out your device...
How about checking arp cache of other devices in your network? On windows or linux: arp -a
tried that, with no success.
I found a backup of my original rom i made with clockwork mod. datadata.img, cache.img, and some other files. might there be a record in one of those files?
is there any way to keep a ROM flash from changing my mac address?
i've flashed 3 times since i've had teh tab and each time i get a new address. it wouldn't be a problem if i didn't have mac filters on my router.
never noticed that and dont know if you could stop it, but you could use busybox to set your mac to whatever you want.
then you could run a boot script to do it every time you reboot.

thanks for the tip. seems that's the route i'm going to have to take. just flashing a modem and i've got another new mac address.
not sure if this would work, but if you were to put the original file back in the directory, then it might be set.
In efs/imei/.nvmac.info
The hidden file .nvmac.info is your mac address.
The file bt.txt is the blue toothe mac address.
Hi there guys.
First I just want to explain that I am not new to Android in general, but have almost no knowledge of Samsung models specifically. It seems they work much differently than my xperia, and so I am lost.
Anyway,
My niece has a Rogers captivate, stock 2.3.3 that was password protected. She changed the password to something new, and the phone glitched and won't accept the pass now.
Her password was very simple, only one word, so we know it was the phone and not her mistake. We tried different spellings, even typos just in case. Didn't work.
Basically, now she's locked out. I read on multiple sites the phone would ask for her email (we know those details ofc), but instead it just does a 30 second timer, then allows the pass to be put in again..
I'm trying to find out how to disable the password without wiping the phone. She has a lot of games, and some apps that are no longer in the market. Is it possible to install recovery and use an update zip to replace the file where that setting is stored? Or alternately, would we be able to access adb from recovery and do it that way?
The bottom line is that we need this:
A way that allows her to keep the apps and personal data while removing the password.
Thanks in advance.
UPDATE: I couldn't find info on adb password removal (I saw for pattern unlock but not password), or loading adb through recovery, so instead I did this:
-Flashed a cwm kernel with Odin
-mounted storage through cwm
-backed up everything from sd to my computer
-installed cm7
She is now enjoying cyanogen although her contacts hadn't been set to sync for some reason, so they're all gone. But hey, at least the phone is usable again.

Hello,
I've problem with some custom roms (full wipe), where I'm not able to connect to WIFI.
Just remark now that in this case, there is no MAC address in advance parameters of wifi configuration.
I've tried to flash from a working rom without wipe data and the wifi works (but rom has bugs). So I think there is an app somwhere (or app's data) that is missing in the problematic rom.
Did anyone know wich application read the MAC addres, so I can try to restore it from a titanium backup?
Thanks
None of these helps?

And instead of eth0 i think to remember it has to either be wlan0 or something very similar to this...
You'll find it out. Try busybox and fixpermissions from within RomManager first.
I've already try to fix permission in Rom Manager.
Just copy the Wifi folder in system\ect of a working rom, try to restore the other rom to compare what I have in it
Thanks !
ok, I give up...
folder system\etc\wifi doesn't matter, there some missing data somewhere else but too lazy to get it work, so I change rom

I can see my mac adress in "/efs/wifi/.mac.info" & "/efs/wifi/.mac.cob"
There is also something about mac in "/etc/wifi/nvram_net.txt" but it doesnt show same adress.
Isn't mac adress somehow coded in the hardware?
I suggest you make a full backup of efs and related partitions if you want to try to change anything, and also make sure you know how to restore them. Messing around with them can get your IMEI wiped.

yes it is coded in hardware but I think I can change it not in hardware but in software because a read about that many times but people did it on the other phones.
Do you think I should change mac adress in "/efs/wifi/.mac.info" & "/efs/wifi/.mac.cob"?
P.S. I haven,t got any problems with doing backup (including efs partition)

Yeah, I guess you can try but you're responsible for what you do with your phone
I doubt your IMEI will get wiped or anything by changing those, if it's even possible.
