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!
Im not responsible for any damage caused. Always Make Backup

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...

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.

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.
Good day, dear forum!
For long time i tried to clean my hacked samsung smartphone. But no luck.
I perfomed FRP in Samsung service center in my town. Situation the same.
Symptoms of hacking:
1. Gmail account hacked. I registered from my email but in registration form i see completely different email, not mine.
2. In my smartphone I see to apps with the same name ("email" and so on).
3. All my apps got all possible permission to acsess my data (network, sd card, system etc). Some of my important files is deleted and destroyed by hacker.
4. When i take affort for defend from hacker (for example, using privacy guide etc), privacy guide panels and factory reset panel become untouchable after 20 min,
although they work well in first minutes after installing OS.
5. I blocked wi-fi and bluetooth connections. I have no wi-fi connection at home. But i see that NFC is running, all my apps connected to wi-fi, phone working very slowly.
I see that phone maked 5 calls during 30 min when it was turned off (!). I think, my phone use hacker's wi-fi.
What i did:
1. Performed FRP in samsung service center. No luck.
2. I installed 4 files service firmware via Odin. The same.
3. I did FRP and installed TWRP, SuperSu, LineageOS v.14. During installation i cleaned Dalvik/ART Cache, Data, Internal Storage, System, Cache.
Also i skiped google and samsung verification. But also no luck.
Finally, i understand that hackers files, apps, peaces of code etc exist not in firmware, but deeper in core.
I think there is another one superuser and he has much more permissions in system then mine.
So, my question is:
-- where i can find and delete extra superuser on my phone,
-- where i can find and delete dangerous app permissions, added by hacker,
-- where i can find and delete dangerous changes (apps, files, pieces of code) added by hacker,
-- what extra actions i can perfom to deleted hacker from my phone (exept FRP and custom OS/firmware)?
There is similar post but i don't see decisions for me
https://forum.xda-developers.com/general/security/trojan-infected-recovery-phone-partition-t3762962
Sorry for long post and my English mistakes. I will be greatly appriciated for any advice!
Yours sencerely, Olga
I cleaned partitions and installed Lineage OS again. Phone changed MAC address Wi-Fi and now use NFC connection and wi-fi. I can't block NFC and Wi-Fi, button is not working. Can you explain me how phone can be hacked if dring the installation i didn't use sim-card or wi-fi? How i can change core settings/use custom core?

it is possible that the hacker installed the software on a partition and updating will not help that. You would need to check all the partitions their size and what are their permissions and compare it to stock, wiping the phone with dd if you have a full software image (the entire hard drive image) will also work but it is a take no chances command.
I currently have the Note 9 and will be transferring to the Note 20 Ultra. What is the best method to transfer EVERYTHING across? I know SmartSwitch doesn't transfer app data. Should I therefore use SmartSwitch first and then use Google to restore the app data? Or vice versa? Or is there a better option?
Is there any difference restoring with SmartSwitch on PC backup vs via USB to USB between the phones?
Cheers
Good questions. For previous transfers, I've used SmartSwitch via USB, Google restore, and Samsung restore, usually jumbled together. I don't have a clear idea of which one does what, or how to select only one method (as I recall, the phone asks for Google and Samsung account information early in the setup process).

I prefer to start fresh, and yes - I know that I lose app configuration. Small price to pay for the weirdness that can happen in some apps when you restore from a backup.
That said, I backup my phone log, messages and such to Samsung Cloud. After loading the base stuff and logging in, I restore those items on the new device so I have message and call log consistency. Then I march through the app store collection and install the apps I want, taking a look at each one to decide if I used it and/or really need it again.
I usually get a fresh clean start when I get a new device.
But the best way to restore everything is to use a combination of Samsung Cloud, Good back ups, and Samsung Smart Switch.
On your Note 9, use Smart Switch to back up your device to the SD Card. Then put that SD card in your Note 20 and restore from there.
I did that going from Note 10+ to Note 10, and it restores all my settings. My quick panel apps. I didn't even have to log back into many of my apps, as it transferred over data from several of them.

So when I was on google products, namely I went from a Pixel to another Pixel recently. ALL of my prior connected wifi networks / SSIDs were fully saved. In other words when I went to my favorite brewery, it's password protected wifi network automatically connected with nothing more to do.
When I moved from Pixel to Note, none of my previously saved wifi network connections were saved. I've only used smartswitch thus far.
Is there anything else I can do to get all of the wifi networks I have saved on my Pixel over to my Note?

I would never transfer your data and settings from the Note 9 to the Note 20 Ultra. There have been numerous posts and threads here about the phone being slow an buggy and the common denominator was transferring from another phone, most had to do a FDR and start over the way they should have done in the first place.

For me, WiFi-network credentials carried over from my N10+ to my N20U. Unfortunately, I have no idea if that was thanks to SmartSwitch, Google cloud backup, or Samsung cloud backup.
Hi guys,
I cracked my 3a's screen so I've just upgraded, but unfortunately a couple of key apps I use (namely language apps which I have tons of progress on and can't migrate over with their systems) aren't transferring the data over. I've tried adb transfer, I've tried looking in the data folders, no dice. I can see my phone's screen when it's plugged into my PC, but the prospect of trying to root it is scary as if I can't see the screen at any point, I'd basically be stuck, and unlocking the bootloader could potentially delete the data on there anyway depending on the method used (haven't looked into this too much just yet).
Any ideas how to get this data off of the 3a? Thanks in advance!
If in this model whether a USB or BT-connected mouse works, you can perform a standard data transfer via a google account.

I've already done that and ADB transfer, only the app itself "transfers" (redownloads off of play store) the app's data itself doesn't transfer.
Just to be clear; this is a non-debuggable app. ADB Backup just results in a 0 byte file. I'm 99% sure I need to root the phone to back this up, but I need to be able to do so while 1. accounting for the blank screen that'll mean I can only see what I'm doing when USB debugging works and 2. without factory resetting the phone in the first place as that'd defeat the whole point.
Any ideas?
I am trying to backup ALL data from internal memory of a samsung galaxy s7 edge sm-G935FD dualsim to transfer to my new samsung galaxy s7 sm-G930FD dualsim
I entered samsung and find my phone account on both devices , logged then into wifi and used backup on edge ,restore for s7,
Used wifi option, selected all data and it only transferred 1.9 gb of the 30gb , then I tryed smart switch which sent 9.7 gb more but still only half, and ran it again it said no space left on device , tho 10 gb data is still missing. Why do both samsungs backup apps seem to transfer random amounts of data instead of everything ?
What is best way or app to transfer everything I need from old to new phone ? I also tryed adb driver /usb cable but failed to get it working.
can it be unstable wifi cause missing data ? Tho its a brand new router with full signal in the next room
SmartSwitch can leave you down miserably. Use for home settings only
You can use the SD card. That should already be your data drive!!! All critical data goes on it.
Copy/paste folders to it, then confirm data size and if readable. Contacts can be backed up by the Samsung phone app as an exportable/importable file.
yes I suppose that should do most apps and data, but it cant access the secure area at all, tho smartswitch also didnt even try to do that. Also not sure if there will be lots of hidden or locked files that make up important settings and data the apps need that will not be readable in this way

SmartSwitch doesn't transfer app data just the apps. It's useful for homepage settings but doesn't configure the app icons or shortcuts. It will restore the theme, icon packs, and some of Good lock apps settings. It's use and reliability are limited.
