Hello,
is there any method to permanent MAC change (WIFI) ?
I can do this by editing some .bin file but after reboot i'm back to stock. Methods like hw addr... doesn't work.
In HTC phones there was easy method to do this via fastboot.
Thanks in advance
Although I do not know any straight-forward solution for your problem, have you ever tried to make a script in /system/etc/init.d which executes the necessary commands? By doing this, it should survive a reboot. Ofcourse for a very short amount of time the old MAC address will be still active, but this might be an easy way to do it.

I already have that solution which stop wifi at boot, change mac(s), reenable wifi, but i was looking for something more permanent

Hi there,
I have an (hopefully easy) problem which I am searching the answer for hours now.
I want to use my android device (4G Systems One Tab) to remotely execute a batch file on my PC via WIFI-Connection.
That's it.
I want to have an Icon on my homescreen and when its clicked the batch-file on the desktop computer is executed. (no feedback or output needed, this is all done by the batch)
I would be grateful if anyone could provide me with a solution or even an idea to find the way.
Thanks

I don't have much experience in bash script but I do know that a software by the name of Script Manager is available in the market and might just help you achieve your goal.
Now with Script Manager you can execute a script you created and place it on a shortcut on the desktop of your phone. The bash script would do any type of calls it needs to do to the PC. As long as your firewalls are well configured and you have port forwarding on the router (if needed) or your on the same wifi network you should be able to do as you need with the tool.
Now also remember, you might want to consider rooting your phone so you can have busybox installed and have a good amount of commands available to you.
Thank you, that was of help. Problem solved.

Sorry for bumping an old thread, but this is my problem exactly as well. I want to run a script to execute a .bat file from my computer.
Could you please go into more detail about HOW you configured "Script Manager"?
Possibly share your script so I can change it to fit my information.
Anyone? Please help.
Thanks.

Thought I would share some info I found when I ran into the wifi problem on my daughter's nabi. I did some searches on the internet and the typical answer I found for solving the wifi issue was "reset the device" or "unroot and return to stock rom - flash all updates and reroot". Being a glutton for punishment, and the fact I didn't want to reset the device, I searched and searched and was able to fix my daughter's wifi without doing a reset or unroot/reroot. Before I get into it I wanted to mention that wifi failures can happen for a number of reasons so while this worked for myself, it may not work for you.
Some prerequisites:
Most importantly; you need a rooted device. If you do not have root access you will not be able to write files or access the commands to fix the issue I am about to outline.
Some knowledge of linux would be helpful, but not necessarily required.
Lets get started:
Warning! It goes without saying but I will say it anyways - you can mess up your nabi by rooting it. Some of the commands below could mess up your nabi bad. If this scares you then you probably should not proceed any further. I am not responsible for any damage you do to your nabi.
Commands are listed between ' and ' - do not use the ' when inputing the commands.
Note: The first two/three steps are not necessary but they do give you insight as to how I was able to determine my problem. If following this doesn't fix the problem for you the logcat output may give you some important info that you can google that may help you fix your particular problem.
Note: Steps 5 and on can be skipped if you have a text editor (vi or nano) on your device. If you have a text editor loaded simply edit the conf file directly.
1. You will need to run the command 'adb logcat' in a command-line window and in your appropriate directory. Adb is available as part of the android sdk but can also be found stand alone since most people do not need the sdk.
2. Try to turn on the wifi. You should see the output of your adb logcat window scroll some data. If the wifi is not attempting to turn on at all sometimes you can move between the settings options then go back to the wifi settings and move the slider. If you cannot get your wifi to turn on you can scroll the window up and attmept to find the data from when the device started up. In the output you should see lines that talk about wlan0 and probably something that says "failed" somewhere. In my case I could see where the wlan0 enabled but then a few lines down it said something about "Line: 25 failed" and "failed to parse file".
3. The file is actually a configuration file used by the wifi kernal module/driver. In my case this file had become corrupted.
4. Set adb in root mode (won't work if the device does not have root access) by running 'adb root' at the command-line. You may need to click on an "allow root permission" window on the actual device after running this command.
5. Run 'adb pull /data/misc/wifi/wpa_supplicant.conf' from command-line. If this does not work then do the following:
a. Run 'adb shell' from command line.
b. 'su'
c. 'cat /data/misc/wifi/wpa_supplicant.conf' - copy the output from the command and paste into a text editor (see note in step 6 on why NOT to use notepad).
d. Save the file as wpa_supplicant.conf, preferrably in the same diretory as adb.
e. 'exit' twice should exit you from the adb shell and return you to your command-line. If all else failes a "ctrl-c" should drop you out of adb.
6. Use a text editor to open wpa_supplicant.conf. The file should be located int he same directory as adb. If you are using Windows I would strongly suggest you NOT use notepad. Notepad will typically change all the EOLs (End Of Line) from \n to \r\n which will really mess things up worse.
7. In the file you should see "network={" entries. There maybe one entry, there maybe many entries. You can remove all lines between "network={" and "}" including the latter themselves. If you see your 'home' network listed you can leave it as the only entry and make sure its priority is set to 1 but it maybe better to remove it as well just in case it contains part of the corrupted data.
8. Save the file.
9. Do 'adb push wpa_supplicant.conf /data/misc/wifi/wpa_supplicant.conf' from command-line. If this does not work then do the following:
a. Run 'adb push wpa_supplicant.conf /sdcard/wpa_supplicant.conf' from command-line.
b. Run 'adb shell'
c. 'su'
d. 'dd if=/sdcard/wpa_supplicant.conf of=/data/misc/wifi/wpa_supplicant.conf'
e. Do 'exit' twice to exit the adb shell. If all else fails then a "ctrl-c" should drop you ot of adb.
10. If the wpa_supplicant file was corrupted then the wifi should now be able to enable and you should now be able to connect to a network.
I hope this is helpful to at least a few people.
Hello,
I have a Dell Venue 8 that is not able to save/remember wifi passwords after a device reboot. I've tried looking into the built.prop file for ro.securestorage.support=true and this line does not exist in that file. I've also read about google backups being potentially the cause, and I've disabled this but the issue remains.
Turning off/on wifi, the wifi is able to immediately reconnect. But the only problem is when the device itself reboots. I've tried looking all over for some sort of "Save" feature when connecting to the wifi network. It does not appear anywhere.
Has anyone else experienced this? Any help is appreciated.
Bump. Can anyone help?
Do you have root? If so, you could see if the networks are being stored in the file:
/data/misc/wifi/wpa_supplicant.conf
If they are, there's no reason they should disappear, I would think, unless as you mentioned, some Google backup process is overwriting it.

No, I do not have root. I am not able to find this file when connecting the tablet via usb to my computer either.
I recommend rooting your device, it took me maybe 10 minutes at most. Backup your data just in case! I didn't loose any files when I rooted, I followed this guide. After you root, download a file explorer and go to /data/misc/wifi and backup then delete wpa_supplicant.conf and do the same with the dhcp folder in /data/misc. I was having the same issues until I did that.
I know this is an old thread, but I just want to let you know my Venue 8 had the same problem and I was able to resolve it by doing a factory reset in the built-in recovery mode.
The multi user and guest account feature is not available on either of the two recent releases of Lollipop for the Z3v. I did some research and it appears this is the case, not only on other Verizon handsets like the Droid Turbo and the Galaxy S5 / S6, but a few other non-VZW devices as well. I'm not sure why it was removed but apparently it's just hidden. It can be enabled and I followed the instructions for doing this for the various other devices and can report that it works for our Z3v (see attached screenshots).
I've kind of cleaned up the instructions and put them below. Usual disclaimer - I'm not responsible for anything that may happen to you or your cat if you choose to do the following. You DO need root access to edit and write to the system file.
** To be safe, please make a backup of your phone and/or a copy of the build.prop file that you are going to edit.
Get ES File Explorer. Run it and enable Root Explorer setting. (You may be able to use any file explorer and editor with root access but this is used most in the instructions and works.)
With ES File Explorer, go to device/system/ and find the file: build.prop
Choose to edit it with ES Note Editor.
Scroll to the end of the file and type in the following:
fw.max_users=5
fw.show_multiuserui=1
Save the file.
I'm not sure if the next step is required but it was in half the instructions I saw, and I did it myself: Click and hold the file, go to Properties, and then change the permissions to Read, Write & Execute. [all three]
Reboot your phone.
When you're up and running, access multi user mode by pulling down your notification shade and then clicking on your user icon at the top right corner.
Notes so far:
A guest user does not have access to the original user's files on the internal drive - the guest user has their own file directory. The guest CAN access the External SD Card, though.
Therefore, an app such as Movie Creator can and will create a "highlight" movie that is composed from photos that are saved on the external SD Card. Just keep this in mind as far as privacy.
There is a per user option that lets you decide whether or not the additional users can use the phone and access the text messages. If you disable this ability, while they cannot open the phone app to make a call, the CAN receive an incoming call.
You can find out more about the nuances of additional users with your Google Fu.
Enjoy!
Wow! Great work!

Thanks! I really wanted this feature and it seemed like not many people care too much about it. It's my way of circumventing the awful permissions control we currently have in Android. That is, there are apps I want to use but refuse to install because of their overreaching permission requirements (contacts, etc) and so I can now create a second user with a new "dummy" Gmail account that has no sensitive information and install these apps without worrying.
By the way, something neat I figured out about this. Additional user accounts are not allowed to side load apps (the toggle to install from unknown sources is grayed out). I figured out that if the main user / owner restores an app through Titanium Backup, any other currently existing user will have it installed for some reason. I don't know why this happens but it's a neat glitch that gets you around that restriction.
Well I think most people simply don't let others touch their phones and so don't have a use for multiple user accounts. I find that my phone, as big as the screen is, is becoming more and more of a computer / tablet replacement. I like the idea of a multiuser functionality, but mostly to hide my own stuff. I'll silk never let anyone else touch my phone!
The use for multi-user that I've seen that makes the most sense is people with children. They will create a user profile for the child so they can't get into any of the parent's stuff or settings. That or the guest profile which will let them do whatever the heck they want without screwing up the phone.
Aside from that I have read that devs find the feature very useful for testing. Heck, that's not a bad idea to install and test apps, in general.
uh oh.
Well something didnt work. Maybe a certain build I have to be on or what. I followed the instructions to a t. Now stuck on endless boot loop. Only bad part is I'm on as hotel room working out of town without a laptop Or pc to fix it. I used a one click root just today and didn't install a proper recovery. Any thoughts

I had a problem with this also twice cause I'm always doing stupid things to my phone my guess is you didn't change the system to r/w but modified it anyway or you used a editor that would let you input the correct values I used s manager I think. As far as getting your phone working you could try safe mode or maybe a factory reset if you can hold power and the volume button down and enter recovery.

I believe the mistake was made when i changed the permissions per instructions. I finially got to my house and im using adb to freeze the loop then going to push a script over to fix the permissions. I will update when i get it done and I will post my fix. Also I used ES file explorer, which i have already used it for years now. Never had anything like this happen before. it just baffles me. I have never got any instructions off of XDA that led to any malfuntion of my phone. But oh well, sh!+ happens.

Hey! I'm so sorry! I got a couple of new phones (Droid Maxx 2 and LG G4) and have been using those phones so I haven't been checking these forums like I was when I just had the Z3v. Really sorry to hear that you ran into that kind of trouble . Thing is, the instructions above are culled from 4 or 5 different sets of instructions for various devices that I found across the web. I performed them step by step myself while cross referencing them to each other and combined them all to the instruction set above as I did it. Did you ever fix it with the method you mentioned? I'm curious if it was the permissions thing (odd, because it worked for me).

it is guys if done right your system needs to be switched to r/w then go back to r/o after modifying the build prop if you modify in r/o you will get bootloop to a hard brick it depends.

Well I kinda fixed it. I went and bought a HTC M9. Lol but not yet, I'm still working on it. I have found scripts to run, even a specific build.prop fix to push, but I have windows 10 and couldn't get adb to find the device. Plus I'm a little rusty. So I broke out my old windows 7 laptop I have used just for rooting an modding phones and tablets. I did get adb and fastboot to find it once. Then some reason lost it. I didn't have it ready to go. But I'm almost 100 percent sure I can get it. Just need to play around with it a little bit more. Having trouble with drivers etc. I will let you know when I have it.
And didn't really hurt my feelings getting the phone I truly want. I never had problems with HTC since I was flashing roms on my old window phones. I just want my pictures I cannot replace.
"Run it and enable Root Explorer setting. (You may be able to use any file explorer and editor with root access but this is used most in the instructions and works.)"
Alas- I am not rooted, and therefore can not enable "Root Explorer" option. Unless someone has some other suggestions- I think I can't do this unless I'm rooted.
Well this is probably what I did to brick my first z3v.
I don't suggest anyone do this at all. There does seem to be an issue with the permission setting on the build.prop file. If it's not reset correctly after editing, you'll get stuck in a loop or worse. I'm stuck in bootloop, but can get into recovery. I made a backup hoping to learn how to edit the build.prop (delete it and rename the copied original to set it back as it was). But I can't even run the original zip that GigaSPX made up for us. (I don't have a backup like I hought I did.)
Anytime I try to install the flashable prerooted zip it tells me it's done after 2 seconds and says;
set_perm: some changes failed
I'm typing this on my z2 tablet, which has the multi user feature enabled. I'm going to see if RootExplorer will give me some clues as to why this doesn't work.
In the mean time I'm hoping someone can help me out?
If love to get this feature to work, but it has to be safe.
Just checked the build.prop on my tablet and got no clue.

a backup usually means going into your twrp and hit the back up button and make a copy of your system including data and all that. This is mandatory before messing with the build prop. If you want Pm me your build prop and I will send it back to you. With multi user enabled.
Yup, I know what a back-up is and how to do it, and I know it's a must before messing with the build.prop. I just really thought I had done it recently...
-and I had! But I forgot that a few days ago I bought myself a Christmas present; a 200 Gb micro SD, and copied most of the contents to the new card from my old one. I chose not to copy the backup because I had planned to make some changes and create a more recent backup. Never happened though because I got side tracked loading music and such. Lol!
So I'm all back together, but would still like to play with this feature. So I'm going to give it another shot.
A guest user does not have access to the original user's files on the internal drive - the guest user has their own file directory. The guest CAN access the External SD Card, though.

Perhaps the wrong thread but: enabled multi user on a Cube T8 only to find that guest and other user can access INTERNAL sd but not external sd. I'd rather have it the other way round. So the kids (other users) can use the whole of 32 GB sd card rather than me having to share the small internal sd with them.
Any ideas how to fix this? Phablet is not rooted btw.
got bootloop..... but i'm safe as i've backup.... through recovery..
I've inserted two lines and fell in bootloop
Thanks bro.. working....!!!! but second step is not needed...
First off, before I get into it; nay sayers and trolls please keep the thread clear. Hopefully we can figure something and more minds together normally equal victory.
Last night an idea hit me, I use a hack with Windows that allows admin permissions and I don't have enough info about android apks to say that it wont work.
In Windows (yes I know they are way different) if you can figure a way to temp change one sys program to be command prompt, you can add users, change admin passwords, delete logs and the such. Basically you own the box at that point. Im not going to go into the details cause as far as I know M $ hasnt fixed it and I dont want them to.
So if we can find an apk with root writing permissions and can change it to be a term emulator we should be able to chmod root.
I have made some attempts, using the hidden menu apk. I figure it can change the prop file it should have root privileges; with no luck. Maybe I am not repackaging the apk correctly or something?
If someone that knows more about apks thinks it may be a possibility lets get to cooking!
The Command Prompt trick you're talking about is very well known. It's been around since Vista and has yet to be patched and unlikely to be due to the nature of how it works.
Thanks Pirate, I know what versions it works with. But I guess no one knows how we can possibly accomplish the same in android.

If you did, wouldn't you end up in a bootloop due to dm-verity, or is this not modifying /system?

The way I understand the DMVerity mechanism is it rebuilds its trust chain every time a legitimate system change is made. When you perform a PRL update, the app makes a change to the system. This does not equal bootloops and I believe we can accomplish the same via this hack, if apk permissions can be loaned.
In the M$ hack you can't leave the change in place as it messes up other processes. Basically you use it to add a user with admin permissions/ open a backdoor and then cover your tracks: which one step is reverting the swap so there are no system issues for the users to find.
Alas, I fear the people this post should be reaching are the ones working towards claiming the bounty and for that reason collaboration will be non-existent.
@Zer0C0oL, please note that unless you are a developer working on a recovery, ROM or a Kernel, you should not be posting the development section. Please refer to this announcement if you have any questions.
I've moved this thread to the How-To section where it belongs.
