Hello, I'm having an issue, I'm rooted with the nand unlock method. I was on flipz .1d but have now moved to .2. I've had this issue a number of times now specificly the "unable to turn on" which seems to be caused by the owner of the /data/misc/wifi/wpa_supplicant.conf file changing to root. but I am not sure what causes the unable to scan for networks to happen.
Some of the things I have done that seem to be a part of the cause: I ran flipz vanilla lock screen fix and I team douche menu unlock, both seem to make changes to /system/framework/
anyone that might know where to look to fix the scan issue? I've searched the forum and have seen a few people have the problem but no solutions yet.
Was having the same problem (came across your post from a Google search).
I got a hint from code.google.com (can't post the link). I renamed the /data/misc/wifi/wpa_supplicant.conf to /data/misc/wifi/wpa_supplicant.bak (rather than delete it), rebooted and all is well.
Seems you can just delete the file, and it'll be respawned on a reboot.
I am having this problem, but on a vibrant that has not been rooted yet.
I cant seem to find the wpa_supplicant.conf, I have tried browsing for it using the built in file manager and using ASTRO, but the data directory is always empty.
Is there a way to fix this without rooting the phone?
if your phone has not been rooted then that means your phone is f**ked up and might need to be exchanged. but this is the evo forum not vibrant. the only way to mess with system files is to be rooted
Appreciate info*, worked in a heartbeat, saved from reloading everything from scratch, which was my way out last time. Witstech A81E Froyo 2.2
*renamed the /data/misc/wifi/wpa_supplicant.conf to /data/misc/wifi/wpa_supplicant.bak
Good eye there mate!!!!

It just recreates the file when your phone gets rebooted. My Thunderbolt is having the EXACT same issue. Ive tried renaming this and deleting as well and still no luck. Im now kicking over any rocks that I can find to get my wifi working.
I have exactly the same problem.
With Root Explorer deleted the file 'wpa_supplicant.conf' but no changes.
WiFi starts up and closes down again with the famous line: "unable to scan for networks"
anyone?

I had the same problem. I installed the software from the sony erikcon website to my computer, and then followed the process for updating the phone software. That did not work, since I had the latest software already. So then, I tried to REPAIR my phone software, and after that was done, my phone was functional again, and the wifi works without any problems.
Requirements:
* A PC connected to the Internet (preferably broadband)
* USB phone-to-PC connection. Please see the accessories compatibility list for your phone.
1. Run the software on the computer after it is installed.
2. Follow the procedure for UPDATE or REPAIR (if you already have the latest version).

I SOLVED WITH FLASH THIS: D12r a33_8723-8703_v11_0312 20141211.IMG
People still use this phone?
Hi,
Just wanted to find out how many people are having the WiFi disconnection/reconnection issue?
I'm thinking of delving deep into the frameworks to fix it, but I'm not sure if it is just a few devices (including mine) or more of a systematic problem.
Thanks
i had the same problem over the last few days. If factory reset didn't work it was a reflash. It works for me now but you never know when it's gonna crash out again.
currently running your 3.1 rooted rom and i'm in Sydney if that makes any difference.
had this issue with the leaked 3.1, Acer_A500_3.019.01_COM_GEN1. i'm using the new stock OTA Acer_A500_4.010.07_COM_GEN1 and haven't had that problem since i upgraded. i'm connecting my Iconia to a home router and a mobile hotspot and both work without problems.
A. if you're rooted, you can just delete dhcpcd-wlan0.lease located in /data/misc/dhcp and try reconnecting.
B. if not, you can try this:
1. Forget the connection
2. Reconnect to the hotspot, this time using Static IP instead of DHCP.
3. Assign a valid IP Address and connect.
i always do option B when i was having the issue.
hope this helps.
Just delete this file in term or root explorer whenever the issue occurs.
/data/misc/dhcp/dhcpcd-wlan0.lease

A brief history of what I've been through before this issue:
My Pro came with 2.2 Froyo from verizon, then flashed Vanilla's CM7 v8 (which is the absolute best ROM I've tested for this phone); no wifi mac address problem here. Then I messed up by installing another recovery, semi-bricked, and forced to SBF to stock Verizon 2.3.3 gingerbread. Then rooted with Pete's Motorola Root Tools, flashed recovery, kernel, wiped, and once again to Vanilla's CM7 v8.
After all this mess, my Wi-Fi MAC address is changing every time wifi goes off/on or reboot, and this is pretty inconvinient for me since both my workplace and home networks have MAC address filter, and changing the router configuration every time I'm forced to reboot my phone is not an option.
YES, I've flashed the Kernel that the developer provides with the ROM.
YES, I've tried reflashing both the rom and the kernel the way the diveloper suggests, doing system/data/cache wipes in between.
NO, this was not happening the first time I've flashed this ROM.
Any suggestions?
Please help!!
SOLVED READ BELOW!
Fix found
Here's the MAC address fix for your Pros running CM7. If you have had an issue connecting to wifi, it's probably because each time the device's wifi is restarted, a new MAC address is generated which will clog up your router as you can easily run out of IP addresses to lease to each and every new MAC address that's generated each time your device's wifi is restarted. The link can be downloaded here. The instructions are simple:
1. Flash CM7MAC.zip (attached) in clockwork no need to wipe anything
2. "Activate it" by going into the terminal emulator app, typing "su" (without the quotes) then typing "mac-address-fix.sh" (without the quotes). A bunch of weird symbols should come up, but that's normal.
What this does is it auto-generates and writes your permanent MAC address to a file called called nvs_map.bin under /data/misc/wifi/nvs_map.bin. It will remain there and your MAC address will remain the same unless you wipe your /data whereas you will simply have to redo it
Note: if you get an error message in the terminal after doing the fix, make sure your Wi-Fi is turned on and you're connected to a network
For CM7, download -->
hi!
my phone does the same, each time WIFI is turned on it generates a temporary MAC address, but the file you mentioned (nvs_map.bin) can't be found in /data/misc/wifi...
could you help me please how the map_gen file is generated? i don't have CWM so i can't flash the zip file, but i have a terminal and two hands
thx
Do we have anything for Android 4.2?

** How can I turn on Wi-Fi when there's no mac-address? No mac-address, no network! **
Hi,
I tried running this shell script but seems like its not executed successfully ... reason i believe so is ...
1. i dont see any wierd symbols coming up ... just a pause for a couple of seconds.
2. i dont see the "/data/misc/wifi/nvs_map.bin' file in the said location.
Please help.
thnx

Is there a solution for this in Marshmallow?
yes this is the best solution
Thanks. This process worked well on my lenovo s650 cyanogenmod 13 custom rom. But could someone explain what is really happening through this solution?
my oppo f1s 64gb, it was dead, recovered working fine, but each restart it changes mac id, and remove all wifi stored connections
is there any solutions?
Seems its pretty common for MediaTek chipsets.
Thanks for the video link!
Hi,
First off i want to state that i have some knowledge of the legal issues concerning changing of MAC addresses and the sole reason that i want to do this is because privacy is a big issue for me and i have a right to enjoy my right. Therefore, any posts or argument concerning such are requested to be posted elsewhere where the topic expressly states so.
Also, please treat me like a newbie when it comes to developing and programming of any kind. I have a very shallow understanding of kernel and the likes.
I am using a rooted S5 G-900H(Exynos with BCM 4534 chip)
Running on 4.4.2 Kitkat stock ROM and Kernel
So without further ado, here is what i have found so far
The MAC address is reflected in a hidden file called .mac.info in the /efs/wifi/ folder. However, editing the file does not change the actual MAC address in anyway. A phone reboot or even turning the wifi on/off will just change it back to the original.
I dumped partitions from /dev/block/ on to my SD card and copied it to my laptop. I searched through the files and found the MAC address in the efs.img partition.My wifi was turned off and the plane was in airplane mode. I modified it and flashed it back using the dd command from terminal emulator on my phone(this can also be done through adb shell but im guessing if you know what that is then you obviously know how to do it).
I rebooted the phone and everything seemed fine. The Wifi MAC address in the status screen in settings displayed my edited address. The .mac.info file also displayed the same. The problem is that it reverted back to the original as soon as i turned on the wifi. The MAC address values in the .mac.info file, status screen and the efs partition from the /dev/block/, all changed back to the original.
I have read that for most phones the important information unique to that particular phone(like IMEI, wifi/BT MAC address, unlock codes and so on) is stored in the NV_DATA.bin file, but everything is encrypted. Also there are only guides as to searching unlock codes and such, so i tried to search for hash blocks randomly using Hex Editor but there was nothing of the sort and the only hash block i can recognize is the one with AES-Encryption as shown from another forum on this site.Maybe it is another type of encryption, but that was another dead end for me.
Then i tried to search and edit various files and kernels as such, but there are no kernels that directly offer this customization. Tried to edit init.tuna.rc but there was no such file in the root directory. Searched init.goldfish.rc and init.wifi.rc and found nothing, but i did see init.svc.macloader mentioned and since i didnt want to mess with programs in the /system/bin/file i left it as is.
Also tried to search through PARAM partition using Hex Editor but nothing was there. Did the same for RADIO and BOOT but i dont think i did find anything major there.
tried to edit /sys/class/net/wlan0/address but it didnt let me, even though i was mounted as r/w. Flashing through dd command on terminal also resulted in permission denied. I was only able to view or dump it. I thought that may have been the source, but modifying the MAC address through the busybox if config command was reflected on the file. which obviously means that its not.
Looked through the dmesg (kernel) log and found a few interesting things but i dont know how to interpret them and what to do with it either. Ill post it later.
There is no NVRAM.txt the only ones in place of it i have are nvram_mfg.txt, nvram_mfg.txt_wisol, nvram_mfg.txt_semco3rd, nvram_net.txt, nvram_net.txt_semco3rd, nvram_net.txt_wisol.
I did do a bit more searching and editing, but i dont recall them right now.
Now, After all that what i think is this.
There is a source for the original MAC address somewhere either hardcoded in the Broadcom chip or somewhere in the partitions under a layer of encyrption.
The Original MAC address is only accessed when the wifi is turned on and not on reboot. This means it is not in any file, program or script that activates on boot, so only scripts and files accessed and imported during the turning on of wifi
must have it. Also while wifi is on and running, busybox ifconfig command changes the MAC address succesfully albeit temporarily, although the change is not seen on the status screen and but it does on the .mac.info file.
Any help from anyone, especially from developers with knowledge of Android kitkat ROm and kernels would be very much appreciated.

As you said, ifconfig changes it, there are several apps that do it for you as well, chainfire also released a mac randomizer app. You also noted it's hardwired in, so i would just have a startup script that changes it if i were you, there night be a better way to do it though.

Yes, I have been using pry-fi as an option but the thing is that when i'm watching videos or downloading large sized files from playstore or other file hosting sites, it starts to turn my wifi on/off several times before becoming stable and logging in to the AP again. I have tried macchanger also and both misbehave after an interval of time. Thats why im trying to search for a more cleaner way to do it.
Running an init script would be nice but i have no idea how to do that. But there should be a script that only runs when turning on the wifi right? Would you know where this file was located and how to modify it? and if so please tell me.

You can just use init.d to make the script, shell scripting isnt very hard and i won't give you a tutorial here. Also as noted many places when researchng changing a mac on android, you can't connect to secured APs, or it won't be easy at least. As i said before, there may be a better way to do this, but i do not know it.

Ok, thanks a lot. Running a script might just be cleaner than anything else I have right now. I'll still be on the lookout for other ways though. Call me hard to please.
Btw, I think the reason most custom MAC addresses(if they do get changed) are too different than the ones registered on the chip. I've found that changing only the 2nd digit out of the 12 in the address, to an even hexadecimal number like 2 or A, works for me on my pc.
Also you need to forget the networks on your pc or android as soon as you change it. Doesnt matter if you have the password or not, it doesnt connect. Must be something to do with the saved info about the ap on the phone that messes it up.

I know on for example ddwrr and even some official router firmwares they allow you to spoof your mac, may be worth looking into how they do it, but i have a suspicion it might be done with a script.

Hard Wired?
I have been messing with 2 Alcatel Ideal 4060a, (because I bricked the first one i had).
After bricking the first 4060a I had, (wiping all partitions), I bought a second, (so I could install TWRP on it back it up and restore the backup onto the first).
After Restoring the backup of the second onto the first, all was good until I tried to get them online together.
When one connected it knocked the other offline, because they both share the same MAC address.
This is my problem and I wish the Mac Addresses were hard wired, then i wouldn't have this problem.
This is good news for anyone who wants to know if mac addresses are indeed hard wired. They are not, (at least not in the 4060a).
Hope This Helps.

MAC for bt and wifi reside in the EEPROM or NVRAM. And that is not editable.
To put it simply you can't change it. Only spoof it. And if you know it's not legal you probably shouldn't be asking.
Reported Is different from original

More info relative to these 2 phones
I installed an app called Change my Mac.
It Lists:
Original MAC 12:34:56:78:90:ab
Current MAC ff:ee:dd:cc:bb:aa
They Are Different.
I thought the original MAC address it's showing, was the one written in the EEPROM or NVRAM,
but it turns out, after installing Change My MAC on the other phone also, its lists the same Original and Current MAC addresses as the first phone.
The Current MAC address listed is the one reported in settings and my network.
I Use Change My MAC to set the reported MAC to the original every time the phone boots using Tasker on only one of them.
Using Change My MAC, the change lasts til boot.
Just passing it on for those that might be interested.
When I get link privileges, I'll add a screenshot of Change My MAC.

Hello Guys, Before flashing we all have our unique mac address in our phone. But after flashing roms, it changed sometimes.
I flashed cm 14.1 and it changed to something weird like 02:00:00... . After many trials i didnt restored to my original one
Problem is , after flashing the cm14.11 rom, when phone first boot-up, it offers us to set it for the first time, there we have to set many things like, language setting/screen pattern/fingerprint/google login/wifi login/sim card select etc.
While setting up these things, when i was connecting to my wifi, i see my mac address was original and everything goes normal. after phone boots-up, i install many apps (as per my requirements). Later, after few hours, when something came up in my mind, i see the status of my phone and there the mac address was weird like 02:00:...
so, i google it to restore my original mac address. I found a method toFix the Wifi issue where it says :-
1) using /persist directory, normally you should see a file named “wlan_mac.bin”, open it with text editor you can see four lines of MAC address, but with the “No Wi-Fi with 02:00:00:...” problem, you can’t see that “wlan_mac.bin” file.
2) Located to another directory “/etc/firmware/wlan/qca_cld”, you should see the “wlan_mac.bin” file now, tap and edit that file, it should be nothing in it.
3) Add your Wi-Fi MAC address to wlan_mac.bin with these format:
Intf0MacAddress=Your Wi-FI MAC address without “:”
Intf1MacAddress=00AA00BB00C2
Intf2MacAddress=00AA00BB00C3
Intf3MacAddress=00AA00BB00C4
4) Save the file and reboot your phone, your phone’s Wi-Fi problem should be fixed.
But what i found on my phone amazes me the most, which is in my both DIRECTORIES (/persist and /etc/firmware/), the mac address written there consists of all 4 lines with my original mac address!
so, if these 2 files located in different directories have same wifi mac address (of 4 lines), then why it is showing me 02:00:00... in settings>status ????
now, guys if you understand my problem, kindly tell the any possible way to restore the mac address in settings to (except saying to reflash the rom clean).
Thanks.
