[ROOT][GUIDE] Permanently Disable WiFi

When you buy a new phone for your child. You want it must be a cool phone, but you also don't want your child uses WiFi function.
I have seen many people wondering here and there to Disable the WiFi permanently in their device. So i thought to make a thread regarding this.
I have seen many posts asking to remove or rename the WiFi Modules to Disable the WiFi but when i tried that unfortunately it failed to delete the Module.
So i moved on for another step and found easy steps to Disable WiFi permanently
Tested & worked in HTC M8 (4.4.2) & Nexus 5 (5.1)
This is a simple trick played in Build.prop which can disable the WiFi of your device for ever.
All you need is :
Rooted Device
ES File Explorer
RB Text Editor
First of all i recommend you to make a system backup with TWRP
here we go :
1. Open ES File Explorer and get Root access
2. Go to system folder and open Build.prop using RB Text Editor (i recommend you to backup original file)
3. Remove the below mentioned lines in Build.prop
Code:
[COLOR="red"]wifi.interface=
wifi.supplicant_scan_interval=[/COLOR]
4. save it and reboot!!
You can notice that WiFi buttons are no longer in use
Warning!

Is there any Way to Disable Mobile Network Internet also ? Like 2G Edge , 3G ,4G etc.,
There is manual option to Disable Data Usage.
Is there any permanent Solution ?

Yes you can disable data permanently....

From my experience you have three options: 1. go into settings and disable your data that way, 2. download an app that allows for easy data on/off switching or 3. which I'm going to do myself when I buy a new (used ebay) phone in the next couple weeks for someone: contact my prepaid carrier and ask them to "disable the data". They can do this at the carrier-level. This will prevent a child for example from re-enabling the data just by clicking a button on their phone. I just verified with my carrier today that they can in fact do this. Good luck!

Hello .. sir ... I had seen that file in that text editor .. i dont found that coding... Nw what i can do.. pls tell me...
[email protected]

This did not work for my phone, as those program lines are not present in my build.prop folder, but I found a solution for my Samsung Galaxy S5 Neo (6.0.1) that I know many others are looking for, it will probably work for all the galaxy models or at least some of them. Here it is:
1. Root your phone using "oneclickroot.com", they will do everything for you, including installing TWRP and SuperSU. Be sure to pay attention to how to access TWRP (Team Win Recovery Project)... for me it was by holding down the volume up, home, and power keys simultaneously and then releasing the power key on seeing red letters. It might vary phone to phone.
2. Make a system backup with TWRP after rooting by accessing TWRP and simply clicking "backup" and then swipe. In the event that you need to restore just access TWRP and click and swipe "restore".
3. Use a file managing app like "Root Browser" by JRummy from google play to go into these file folders: "system/etc/wifi"
4. In the Wifi folder delete the first four files:
bcmdhd_apsta.bin
bcmdhd_ibss.bin
bcmd_mfg.bin
bcmd_sta.bin
4. Now reboot your phone by simply turning it off and back on again.
5. All done, your phone's wifi will no longer work.
6. If for whatever reason you don't want to be able to get it back ever again, just go delete your system backup in TWRP and you won't be able to get it back.
If you don't see these files in your phone after rooting, don't be discouraged. I figured it out with a little experimentation and I knew absolutely nothing about programming or androids... I still don't. Just make a system backup with TWRP and experiment by deleting different files that have "Wifi" in their name. Only delete one at a time or a small group of files at a time, and restart the phone every time as programming changes will not take effect until you do. Every time you brick (disable) the phone, just use TWRP to restore your OS (Operating System) using your TWRP backup. It only takes about 2 minutes to restore every time. I bricked my phone about 4 times in the process of figuring this out. Very simple and easy.
Also, your carrier will usually be willing to apply a "data block" to your account if you call them. For $2/month Koodo will apply a data block that makes it impossible to access data.

If I did this to disable wi-fi on my child's phone, could they simply undo it by doing a factory reset of the phone?

Disable Wifi on Moto G6 / Pie
I recently had to do the same thing with my child's phone. She was just too good at circumventing the usual child protections and getting on the internet to surf adult material and chat with random stalkers halfway around the planet.
She has a Moto G6 with Android 9.0 PIE.
1. Rooted it
2. Loaded a file manager and after much trial and error found that wifi could be disabled with name changes on:
/vendor/lib/modules/wlan.ko -> wlan.bak
/vendor/lib/modules/pronto_wlan.ko -> pronto_wlan.back
Then, reboot the phone.
The user can attempt to start wifi, but it fails. No boot issues.

Yes, they could. That's why I also used Google Family Link to set up a minor child account for her and made it the main account for the phone after I changed the file names above, but before rebooting. GLF prevents a factor reset from within the phone or changing the user. She could try to boot into recovery and perform a factory flash, but then it's going to want the same google account as before....and she doesn't have the password. Fastboot is locked as well. The only issue you might have is that google somehow thinks all 14 yr-olds should be independent enough to remove supervision, but I guess you could do the same thing that the kids do to get around age limits - change the birth date.
I also shut off data at the wireless provider.
Now, she's got a smart phone that calls and texts, but can't get on the internet or play store. Also, without the internet, no updates that will wipe out these changes.

Does not work for me
Hi
I have a Samsung Galaxy Grand Prime with LineageOs, rooted. I didnt find the files you were speaking about.
Except build.prop, but the mentioned lines didnt even exist in my phone files. Is there any other way to disable wifi permanently ?
Thanks

Sorry for the bump, but I really need to disable wifi in a Android 10 LineageOS based rom, but none of this solutions works...
How can I do this?

How to find Driver Files to disable the Wifi
There were a couple of bumps on this thread regarding driver files for wifi and how people weren't able to find these files on their phone.
The answer is that if you don't see the driver files mentioned in the thread above, it's because they're called something else, if they exist at all.
For the Moto 6, I spent a fair amount time doing trial and error renaming of system files until something worked. It took me some time and research to determine that for PIE, the .ko files represented some sort of driver files. Then, I went searching for .ko files with wifi in them, and then finally, I located the two files mentioned in the thread above. For your phone, they may be in a completely different directory, or named something different.
I knew that I had figured it out when I booted the phone, and was unable to get the wifi to work or even detect any signal.
Maybe there's a parameter file on your phone that controls the wifi settings, or maybe you rename driver files like I did.
I've done this a couple of times now on my kid's phones, and for each phone, the driver files were different. The last phone I did, I went ahead and posted to this forum so maybe someone else can get some benefit.
Best of luck!

An alternative solution for this issue is to assign a wrong universal local IP address for all wifi connections and the final user cant change it... Just Saying.

That's in interesting concept. How would you do this on an Android phone?

Well Well Well, I'm just 2 years late bumped on this thread .
It's Andoid 11 minimum in these times or even 12 & now 13 is also available.
But I managed to keep Wifi off while keeping Bluetooth Pairing & BT file transfers On, Hotspot On & Data On specially because Flight Mode no longer Disables WiFi, Bluetooth & Hotspot (only keeps Data off) since andoid 9 i think.
------------------ Worked on Andoid 11 GSI, Galaxy M-Series -----------------
I] If you just want WiFi disabled permanently, then Here are the steps that worked :
> Install Magisk or SuperSU And Optionally TWRP/Any Custom Recovery
> Install any Root Exploration app & grant it Root permissions
> Create a Backup (nandroid or anything that can backup your data)
> Using the Root Exploration app navigate to (vendor/etc/wifi)
> Look for the file ( wpa_supplicant_overlay.conf ), Tap and select Text Editor option
> Change to this -> [ p2p_disabled=0 ] , [ update_config=0 ], [ pmf=0 ] then tap Save.
> Reboot.
> Go to Settings >> Apps >> Bluetooth MIDI Service >> Reset the app
> Go to Settings >> Apps >> Bluetooth >> Reset the app
> Reset Network Settings (Settings >> System >> Reset Options >> Reset WiFi, Mobile & Bluetooth)
> Reset Firewall Settings(AFFirewall+, Netguard etc.)
> Reboot to Recovery
> Wipe Dalvik/ART Cache & Cache
> Reboot to System
Now WiFi & Location should be permanently disabled but you can still connect BT wireless & send/receive BT files (mp3, jpeg etc. but not apk, exe etc.) also Hotspot, Data , Manual Location (Not GPS Location) works.
#BUGS: Windows does not Connect Automatically to phone Hotspot, manual reconnect needed everytime. GPS Location breaks but Manual Location entry can be picked-up by apps like Opera Browser etc.
II] There is also another same way to get WiFi, BT, Hotspot Disabled while keeping ONLY Data Enabled but that was not the original question on this post so no need I guess.

[Completed] Can't change/delete wifi network in marshmallow.

Hi,
I don't know exactly where to look for help. Because, it could be a CM13 problem, a Oneplus One problem, a Titanium Backup Problem or a general Marshmallow problem. Please guide me in the right direction, where I could ask! (Or if you know the answer, I would be even happier).
///(writing this after everything followingWow, I really wrote A LOT. tl;dr: I can’t edit/delete my wifi connections on Marshmallow. I think, it’s because a new rule of Android 6, which prevents other apps (in my case my network settings) to change stuff (See paragraph 6). I have 2 assumptions (paragraph 7+8) but I still don’t know, how to change/delete my wifi connections. help!///
I also want to say, that I already asked in some german boards (hence I'm from germany), where I was immediately dismissed, because quote: "It's your fault if you install nightlies. You don't get help, if you are so stupid". Well I can't understand this point of view to some extend, but I still don't know, if its really a "nightly problem" or one of the other suspects. Please don't dismiss me directly. If you have a clue, please point it out.
Please also note, that I have under 10 posts, which prevent me to post links. I really don't want to spam and I hope I don't break any rules, but I included links to pictures in my posts. Not to spam, but because I think it's helps understanding my problem.
So lets get to it:
The used status: I was on the official CM12.1 nightly and have done updates 1-2 times a week. At university I use a TTLS/PAP connection with a certificate and my credentials (eduroam -> eduroam. org/index.php?p=faq#technology). At home and work I used a normal WPA2 connection.
What I did: I updated yesterday to official CM13 nightly with OpenGapps for Android 6. Not via the updater, but via Recovery. I did a full system backup beforehand with Titanium Backup. Booted into recovery (TWRP), wiped the usual stuff (factory reset + system partition), installed CM13 and OGapps, rebooted and setup the phone. Then I did a full restore (all data + missing apps, cause I didn't want titanium to overwrite the new Gapps). Everything worked out great. Phone runs great, my daily apps run great, no crash so far. Quite nice for such an early nightly.
Now my problem: I went to my university library 2 hours ago to work on some things in the evening. My phone is was not able to connect to the wifi (authentication problems). Than I tried to edit the network and saw, that the settings were lost (as well as the certificate). I downloaded and installed the certificate and set everything up in the edit network panel. On save, it just gave me the message: Couldn't save network (imgur. com/fBDctvE.png). So I tried to delete the network, to set it up from scratch, but I can't delete it (imgur. com/2I29bSR.png).
I did some research I found people who had (It looked like at that moment) the same problem, of not be able to edit or delete a wifi connection. So one pointed out, to settings -> backup and restore -> and reset all network connections to factory state. I did that, but all the saved connections are still there. It can't delete them. Then somebody else with such a problem, said, he couldn't delete his network setups, but with an external app (WiFi Manager) he was able to delete the networks.
Which brings me to my current point in time: I tried the app, it was not able to edit or remove my networks, but it gave me one valuable information, which is maybe the key to my problem: imgur.com/ t2JmYml.png . It says, that: "Under Android 6 only the application, which created the network, is able to edit and to remove it."
Now I have 2 assumptions:
1) It’s a problem because I restored my data via Titanium Backup. If I look at my saved networks, than I also see, that the „owner app“ is now indeed Titanium Backup (imgur. com/I44ys5s.png) and NOT network settings. Which, if I understood correctly would prohibit network settings to change or delete networks, because of: "Under Android 6 only the application, which created the network, is able to edit and to remove it.“
2) It has nothing to do with Titanium, but instead is a problem, because the networks were created with the older version of Network settings (Gapps for Lollipop). And I did a fresh install of Gapps for Marshmallow. So maybe „new“ Network settings thinks, that it didn’t create the networks, but instead they were created by „old“ Network settings.
Either way, thats it. I really don’t want to install Lollipop again just to delete the networks and than again install Marshmallow and recover everything and setup stuff.
Did I miss something? Do you have different ideas, what I could try? I have root and busybox installed, could I maybe delete the networks „manually“ via Terminal Emulator, or could I adb into my phone and search and delete these settings? I was not able to find them, but honestly: Without somebody here pointing me at the right direction, where the network profiles are stored, I would not mess around on my own. Can you help me?
Thank you!!!

Hi,
To better assist you, please post your device model number and I will guide you to where you may find your answer.

App data transfer without root?

Trying to migrate some of my more critical data from my HTC 10 to my S8+, used Helium but it's a bit crash happy right now, and what it did migrate is virtually useless. Is there a manual method I can follow? I have done an ADB backup as well but it seems rather small @ 3gb even though I have 11gb in app data.
Because I've always had root, TiBu was my goto tool. If there are any advanced methods using ADB or something else (I've done alot of searching) to backup and restore data to a phone without root, I'm all ears. Hopefully it can help others besides myself as well.

Hi Opieum, Unfortunately I am not here to answer your question but to second it...
Based on my research I can't transfer app data from my s7, apps transferred, even sideloaded apps using SmartSwitch, but bluetooth, wifi, accounts and other app data would not switch . I even used cable method.
Helium which is supposedly a great app that does not require root unfortunately also fails to restore app data on the s8 as other users have reported on here and on Reddit
I have an s7 and before I trade it in I want to make sure all my app data is transferred, at least a full backup on my pc. I do not trust SmartSwitch to backup everything

I am also trying to transfer my app data from my rooted s6. Helium wont work, smart switch wont transfer app data. Has anyone found a way of doing it without rooting their s8?

Helium is the only app that works so far, make sure you use app data backup only. If you want to backup sms/mms/call logs just use mybackup from the playstore.

I was actually looking at this earlier, thinking I could just copy the app folder from my old rooted android onto the new one, but I couldnt even find any files in the app folder to move over! just tried helium, backed up one apps data, restored it on my s8 but it had no effect at all.

Helium wont work for me either keep getting the desktop password error even though password is set to blank. Have tried removing lock screen and turning off private mode.

Remove any screen locks that you have, fingerprint/pattern/pin.

Premium helps but just do app data only backup, then copy the /carbon directory to the new phone and restore from internal storage.

I tried all of this and even tried setting a password in heilum and dev settings but still no luck. Looks like ill either have to root the s8 (trying to aviod it), or give up on my old app data annoyingly as some apps i have dragged data across multiple phones for upto the last 5 years.
Surely there is another way aside from root options.

Transfer App Backup in Google Drive to an other phone

Hi guys!
My phones display recently died and therefore cannot be used anymore. Luckyly it still connects to Google and the settings and apps are backed up, at least so I thought. But in fact, when I got my new phone, which is the same model, there was not step during initial setup to transfer data from a previous device (i can see there are available backups in GDrive however). Do you guys know how I can trigger the recovery of the data in Google Drive? It doesn't even copy my settings, nothing. In Backup & Reset Automatic restore is enabled.
I'm really desparate, I just want a working phone and setting all the apps up again is such a major hassle...
And tip or hint would be helpful, thanks!
Also: It's a Moto Z play

Samsung Data Recovery

Hello,
I wanted to know if there is any way to recover old data from a wiped phone (pictures, notes, Whatsapp data). My phone had a max incorrect attempt limit which would wipe the phone data if reached. I tried to use my backup that I had but Google is requiring my old PIN code for my lock screen. I can't remember the PIN, as far as Whatsapp is concerned, apparently the backup did not save to Google drive ( I think it may have been set to save locally). Any help would be appreciated!

I am trying to help where I just googled for what the answer might be and there seems to be a bunch of ways to recover deleted data (although I'm sure the level of success depends on how well it was deleted and wiped clean and overwritten multiple times with all zeroes, etc.).
Here are some of those hits which "might" help (you'll have to test them).
