Hi,
I don't have lucky patcher installed and have gone thru the FAQ section to fix this issue but problem still remains. I have one tablet that Pro stays activated, but it does not stay activated on my Android TV box. I think the cause is that the tablet which works has an inbuilt battery, so the date/time is always correct (regardless of internet being on/off), whereas the android box has no battery and if you switch on the box without an internet connection (I usually do this as the main reason for the box is to watch my 600+ films from my external HDD), the date/time goes back to 1970 and the license verification issue appears.
I'm assuming this is the cause of the problem as when I first install Pro on the TV box from google play store (with internet on), Pro says it is activated. It's when I reboot without the internet on, that the problem occurs.
Any ideas? (apart from keeping internet on all the time )
Just confirmed that it is system date related, by trying a few scenarios. I can fix the problem by having the internet on when I boot the TV box (and system date is automatically updated from the net), then Pro says it's activated. Once the date is set, it appears that I can then turn off the internet and use Pro until the next boot. However, if I boot with internet off and try to use Pro, I get the license error.
If I boot with internet off, then fix system date manually, I still get Pro license error, so I assume Pro does some initial license check the first time you use Pro after a boot, and the internet must be on for this to happen.

Once it's activated it can work without internet.
There is a another possibility that the data partition where mx player stores app data getting erased upon reboot or it might be stored in Ram.
In this case, MX Player will try to verify the license since old data got erased. But, Invalid system time settings will lead to the issues with connctivity to google license validation servers. So, MX Player will throw the error.

Thanks for the response.
It's not a particularly big issue for me, as I have other video apps to choose from. Just thought it was worth putting it "out there".
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.

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.
Hello!
I'm on Holiday and have a big problem with my OPO. I use Lineageos 14.1 (Build from march) and after the battery was empty yesterday I have a lot of problems today:
- no wifi connection. It is not possible to switch it on or off. No wlan is recognized.
- it is not possible to reboot or shutdown the phone. I need to press the powerbutton for 10seconds
- the battery monitor shows nothing. No power usage of the apps and no battery chart.
- the phone is getting hot and has a really high battery drain.
This problems occured after the empty battery yesterday.
I already wiped dalviak and Cache and updated to the latest build. No change.
Do you have an idea? As I said I am on holiday and the day befor my wife laptop's SSD died- so I have very limited possibilities. As wifi is not working, I write this with an IPhone, which is no fun
I downloaded the update on my OPO by cellular which is still working but no good idea because of limited data plan...
Many thanks for your help!

Factory reset?
That would hopefully help- but I will loose all my apps...
A question: will my pics and downloads still be there? Maybe I make a Titanium backup, do a factory reset, restore the backup and everything will be fine?
What data will I loose?apps and the folder "Android"?
And: reset in Anroid or TWRP?
Many thanks!
It works! It seems, that the wifi settings were corrupt. I read a solution here: https://android.stackexchange.com/questions/28567/how-to-reset-wi-fi-settings
I deleted the file /data/misc/wifi/wpa_supplicant.conf , rebooted and now wifi is connected again.
I See the battery chart and can reboot with the restart menu

If you factory reset from TWRP, internal storage won't be touched hence photos and files will remain. But data partition will be wiped and that contains the apps and their saved info.

Factory reset when on holidays is hectic anyway.
Enjoy your holidays!
Thanks I don't wanted it hectic, my wife was already nerved by repairing my phone
And another information: before the phone was empty, I installed the facebook APP and allowed the Option "show nearby wifi" (I don't know the real english translation for this).
Maybe this had to do with the damaged wifi settings...

Hey So im new to the comunity and i reached out to this site before because, I was almost 100% sure my phone was Hacked. I shared a few screens and someone told me to factory reset. before resetting i tried to backup my photos and everything i could to the online drives i could back up some and others i couldnt i noticed the file names for pretty much everything was in a folder called
/storage/emulated/0/.face/ .revitalimage
so i factory reset just to find out that all my backups were deleted/
i have many folders i cant access and when it says optimizing apps right after the reset i still somehow had 900+ apps right off no sign in or anything
i took these screens to see if anyone can help me
my data usage is through the roof and my ram is always running like 98 processes, and wont close most.
i dont know if verizon phones are always unlocked but my phone has been unlocked ive tried rooting but it wont even let me do that.
Malwarefox doesnt find anything .
and when i look up Half the files in the pictures i cant find anything ..
Thank you in Advance Kyle
What really is your issue? What do you mean with "data usage is through the roof"? The amout of Cellular Data Usage?
BTW: Unused RAM is wasted RAM.
FYI: Android kicks off apps when RAM goes low. CPU throttles speed automatically when its temparature goes too high.

Like I said after I reset it still had thousands of apps on here that are unacccessible it encrypts my photo so I can't save them myself and or transfer them I can't view any of my installed apps app data I'm unable to use my Bluetooth tethering and/or hotspot when I try to activate it and just automatically closes I completely turned off all of the background data usage for pretty much everything on my phone and it's still just consumed whether I'm on Wi-Fi or not
Hi all.
I have searched quite a bit and have found no answer to this problem yet.
So the phone is fresh from factory reset. Phone is pre-owned. Never connected to any wifi network and the wifi always remained off. Same goes with mobile data, never turned on. What's even more interesting is the sim is a prepaid simcard with no credits and no data. The simcard is intended to receive text and calls. (No cost to receive calls or sms). So data leak from that isn't possible either.
I have seen hidden downloaders from carrier that downloads bloatware by itself before. But this is the first time I've ever seen it self download apps without any data connection.
The built-in data usage counter still shows 0. The phone has never connected to anything. But now several bloatware apps just showed up. And those apps do work and storage used has increased. I noticed this around 24 hours after the reset.
Can someone please explain what is going on?
Do phones have secret functions to access data undetected by wifi or carrier?
The phone manufacturer is a one of the major brands and probably the largest that don't have access to GMS.

Some devices have system apps that can be "uninstall", but they don't actually uninstall completely because the uninstalled apps are stored in a hidden partition. But, once uninstalled, if the device is factory reset, the apps automatically reinstall themselves from the hidden partition, similar to when resetting a PC to factory defaults. I had a tablet that would do this, the apps were definitely uninstalled but would reinstall from the hidden partition when I would factory reset the device, then I would have to uninstall those apps again. This would happen every time I did a factory reset.

Thanks for the answer.
Yes I understand that part of uninstall. But the difference here is those apps never returned fresh from factory reset. It returned hours after using the phone. The first few hours of using the phone, those apps doesn't exist, doesn't even show up on the free space count. It wasn't until the next day those apps appear.
I did suspect what you said too, but I can't explain why it waited at least 18-24 hours delay before installing itself and show up on the phone. If that was the case, it should have appeared right after the reset.

Yes, I considered that also. The only other thing I could imagine is that maybe you installed something and then whatever that was installed the additional apps.
Questions of a hidden Google mesh network come to mind after reading this. I guess it's theoretically possible via Wi-Fi or Bluetooth between devices. I don't know.
So after trying to gather more information.
I believe it is installed from some "hidden partition" by some hidden app installer.
The reason is.
1. No data of what so ever is connected.
2. The installed app version is old, as in few months before the official release.
What is intriguing is.
1. The delay before installing this app (and through an installer), rather than just install it fresh from reset.
2. It doesn't appear to be consuming and storage, as if this hidden partition cannot even be seen. Once the app appears, the storage usage increases.

I actually believe it is a thing. I vaguely remember that my brand new iPhone detected and recommended my current location region without even inserting a simcard or connecting to wifi yet. The kicker is, phone was purchased in another country that is separated by vast ocean and several time zones.
To this day I still can't figure out how did the iPhone know that. I suspect that the wifi routers broadcast more than just SSID to any device that is not connected. Or it could be from another iPhone. Maybe some similar bluetooth tech that predates "Airtag". This was about 3-4 years ago, likely it was the X.

Location is detetmined by more than just mobile data and Wi-Fi, it also uses the regular cellular part of the radio. The cellular part of the radio works even without an active SIM. That is why the emergency location and emergency call features work even without the device being activated on a network so that you can make emergency calls and your location can be tracked in emergency situations so that you can be found if you need help or rescue.
