is there any way to totally disable the network (tablet) - Fire Q&A, Help & Troubleshooting

Ok i don't know if this the right forum but i looking to give out to a few workers phones or tablets that have no internet access at all (i only want them to use if for calls and SMS - i not going to explain why i want it that way). i'm looking for an easy way to disable the network altogether.
i've got a GT-S6310 SAMSUNG or fire tablet. i tried an idea that i got into the platform.xml file (with the RomToolBox app) that is located in the etc/permission folder and erased the internet line>save and then restart and it worked. but there many problems like apps that crashed without even opening theme like google services.
i'm looking to just erase or change one file in the system to get to my goal. i'm sure that there are very specific files that are critical for the internet to work and if they are disabled or changed the internet access would go down. please help

This device (5th gen Fire) has no mobile radio so is off the table for your requirements. If you plan to leverage WiFi calling/SMS then that uses data, aka "the internet". Crafty individuals will easily circumvent any blocks applied at the ROM level unless device is rooted and you use secondary accounts. A bit harder to work around but still fairly easy to penetrate.

Rooted decive! So what can i do? What system file can i erase to stop any internet connection? Or maybe something that has to do with the buildprop file

Look into selectively blocking internet access via third party firewall, hosts file or VPN. Likely need to create secondary/child accounts to limit access to the filtering tools. You'll need to do some searching/testing to find a solution that meets your requirements. Probably not the right device for what you are trying to accomplish.

[Q] lumia 521 metropcs

is there anyway to root or jailbreak the lumia 521?
only had it for one day and i hate it.. anyone find a root or jailbreak?
1) Learn to search.
2) Not yet (duh, if you'd searched you'd know).
3) Why the heck did you get a phone without doing even basic research?
4) Is there something *specific* you want to do? There are some tricks possible with stock dev-unlock.
All of the above and what do you think your going to be able to do once its "broken" ...there's not a lot really hidden from you at the moment. One of the beauties of WM is there's practically no real need to root it or at least no huge gain atm.

Oh, I *quite* disagree with that last statement. Things that I've done, even with the limited control available right now:
Moved the map data folder to the SD card.
Made my ATIV S show three normal tile columns on Start.
Been able to sideload more than 10 applications at once (and 10 is the limit for a paid account; free ones get 2 or 3).
Been able to directly sideload my ebooks.
Make an app to enable wired tethering on my phone (isn't limited like WiFi tethering, which doesn't work for me anyhow... another thing I hope to fix, though).
Set up custom theme colors.
Access the certificate store.
Edit the HOSTS file.
Add IE favorites easily.
There's a ton more that I'm still investigating, too:
Changing file associations, even ones that are supposed to be locked to built-in apps (like .MP3).
Custom system components (replace or modify the keyboard or Start screen).
Port Win32 programs, even ones that require drivers such as openvpn.
Change the default search engine.
Make the ringtone volume controllable separately from the system volume.
Toggle services on and off with one tap.
Enable raw network sockets (support other protocols than TCP and UDP, do security testing from my phone, etc.)
Lots more...

I was trying to find the practicality on doing it for WP8, but I couldn't recall exactly what all was added feature wise on WP7. This kind of clears things up why InteropUnlock is so valuable.

Windows phone security- is there one and if so, how does it work?

Hi,
So, Android has a permission system which albeit somewhat flawed (malware can gain permissions not intended for it) and not very suitable for laymen (non rooted phones have to either accept all permissions or be denied from the app. In many programs people don't have the luxury of not using them) theoretically has merit. IOS has...well actually I'm not sure how it works security wise but I pressume it creates sandboxes for each app, layman wise it is reasonable since you (theoretically) can deny access for all programs to certain components (no need to jailbreak).
How does WP works?
Thank you.
Security is different, apps can't do as much as on android. But iOS is better in this, because capabilities are like in Android: you can see what the apps want prior to installing them, but blocking some of them isn't possible.
I am very saddened to hear this.
Is there an ability in place similar to Androids rooting?
Also, what do you mean by "apps can't do as much as on android"?
Thank you!
@th0mas96's post is technically *mostly* accurate but very confusing and doesn't actually answer your question at all.
The short version is that WP apps use a capability-and-sandbox system much like iOS and Android, with each app getting a sandbox that gives it read-only access to the app-specific install directory and the global system directory, read/write access to the app-specific data directory, and access to whatever other stuff is specified in the capabilities. Capabilities are currently all-or-nothing; you can't reject or disable any capability except by just not installing the app.
I could go into the technical implementation of the system a bit, but the short version is that WP8 apps use fairly standard NT (as in the NT kernel that is at the core of PC Windows versions) security features: each app has a unique token (rather than inheriting the token of the process that crated it, the way it normally works on PC but very much like how Windows Store apps work on Win8) which contains the app-specific Security IDentifier (SID) that gives access to the app directories, plus the SIDs of the various capabilities that the app has.
What @th0mas96 was talking about is that WP capabilities usable by third-party developers are much more restrictive than they are on Android. For example, Android allows an app have full read-write access to your contacts or to send SMS directly. WP8 doesn't allow that unless you use capabilities that are normally neither allowed on the store nor allowed in sideloaded apps (Microsoft's code can have them, of course - that's how the built-in SMS app works - but not Joe Random Dev). The downside of this is obvious; some app behaviors (like a full replacement for the SMS app or phone dialer) are not possible. The upside is that apps are *way* more limited in how malicious they can be; the most common way that Android malware makes money (remember, the vast majority of malware is for profit) is by sending SMS to "premium" numbers. On WP8, an app could *compose* such a message, but it couldn't *send* it for you (unless it had a capability that third-party apps normally can't have) so you'd have a chance to see what the app was doing and decide not to send that message after all.
This means that the ability to disable capabilities is much less important on WP8 than on Android.
Oh, then those restrictions are actually good news.
Aside from from your typical run-of-the-mill malware my main concern was actually privacy. I have a huge displeasure from apps like Whatsapp which on android takes a whole plethora of liberties and was hoping that perhaps some other system may contain their user data voracity and their ability to control the divice their on.
Is there any link in which I could see the full list of those restrictions?
I'm still downhearted from not having a more fine grained control of the system but maybe it still has it uses in some scenarios...
Also, thank you very much for your comprehensive explanation!
i found a tiny file stored inside some of the unbranded htc accord RUUs. its call disablewriteprotect.test. the only thing the file contains is a sentence stating write protection will be disabled until this file is removed. followed by a music note and some other symbol. so there you go thats how you make your entire htc 8x read and write. one file less than 1kb in size. ROOT!
but how can we flash this file. im still working on it. this file is located within the efi partition which also houses the ffuloader.efi, and severl other efi executables. check this post http://forum.xda-developers.com/showthread.php?p=53687985#post53687985

I pressume this is an advert for Master Software Solutions, but nevertheless I did google the term you suggested and got nil results. I also browsed the main site of the company itself but haven't found anything related, nor did I find anything on their facebook page.
Regardless, I checked out this Kids corner thing, it's cute but not really security related...
Thx anyway.

[Help] My saved Wifi doesn't restore.

I have many saved wifi networks including passwords saved on my old Samsung Galaxy S4. But I have not got them on my Nexus 6.
I have tried to sync Google account but I will not received any wifi networks on my Nexus 6.
I have root on both S4 and the Nexus 6. What can I do?

I won't begin to guess which apps might properly back up (and then restore) the wifi configurations across devices. Sometimes they work. Sometimes they don't. (I think Titanium Backup might work, but I've never used it myself to verify.)
However, you should be able to recover the wifi configurations from your SGS4 and then manually configure them on the nexus6. This assumes that your comfortable in a root capable file explorer or command shell...
First, google "where does android store wifi passwords." Using the information from there (and with root access,) you should be able to track down the proper file on your SGS4 to extract the existing wifi configs.
At that point, I'd actually suggest reconfiguring the networks on your nexus6 using the "settings" application instead of trying to manually write them into a file. (In theory, you could edit the proper file on the nexus6, reboot, and they'd all be there. In practice, even the slightest typo or misunderstanding of the file format could result in Really Strange Things happening.)

Thanks so much for your reply!
I have seen that there are many wifi Recovery apps on Google play, but I don't dare try any because it can cause trouble I think.
I am frustrated and surprised that my wifi network that I have on my S4 does not want to show up on my N6. It is very strange!
But thanks to your help, I have found all the passwords via the file explorer on the S4, so I have to type in all manually on the N6 then
I was trying to do this too and actually found a way to do it, using google backup service. I forced the restore through adb shell. See this link: http://jftr.de/2014/01/fairphone-and-android-backups-to-the-google-cloud/
just thought to share it here, since this is the top hit on google

626s vm hot spot

Hey everyone I'm rooted and everything so I've been trying to find a way to get around paying $30 for a hot spot that should come with the phone. anyways I found a way to disable the "you are not subscribed to hot spot" thing but when I connect anything to the hot spot I keep getting errors saying the DNS couldn't resolve server names. I tried for hours with different DNS servers so I'm guessing it's something vm has done. If anyone could help me with this I would greatly appreciate it I used it a lot before I got this phone and now I'm kinda stuck :/
I know from experience that you can usb tether with pdanet and it'll hide your tethering with metro. It will not however hide hotspot HOW EVER you can use its experimental feature internet sharing which is essence creates a hotspot however I've only ever been able to connect to a phone that was with metro AND the phone that was hotspotting was not with metro. Trying to do so with my metro phone give me dns errors as well.
I haven't tried to use USB tethering yet only because some of my things can't be tethered via USB. I just don't see why I'd be getting DNS errors now and never did before. Oh wel. Surely someone here will have a solution for me soon.

I don't know if you are rooted, but I'm using Wifi Tether Router (just google an apk file) instead of trying for the native hotspot function.

Are you sure? I tried this app before and it wouldn't broadcast the network. And yes I am rooted. I found a way to partially get the native hotspot working but it's a pain in the butt. If I could figure out how to edit the apn settings I'd have it going in 5 seconds but they're locked and htc phones don't have a "hidden menu" like lg phones.
Weird... Well, If you can't get that working, I'll let you know my current configurations for that app.
keep up the good work guys.
I'm looking for a solution for the hotspot on my 626 from Verizon.
native mobile hotspot and tether on cricket
I was able to use the phone as a wifi hotspot by doing the following:
1) install the following apps: MK explorer, Axel (xml editor)
2) phone must be rooted
3) using MK explorer navigate to the following folder (root directory): /system/customize/ACC
4) make a copy of the default.xml file and rename it in case it gets corrupted
5) run Axel and open the default.xml file for editing
6) scroll down about 80% from the top of the file to find the entry (find didn't work for me):
<app
name="Tethering_provision">
^ <item
type="integer"
name="TetheringGuard_Rule">
. 3 (note:dot is in middle)
7) edit the entry to change the 3 to 0
8) use "save as" and save modified file
9) rename the edited file to default.xml
10) reboot
11) go to settings->more->mobile hotspot and tethering, click on Mobile Hotspot, click on OK, change the hotspot name and password to what you want
12) after this step the phone just sat there so I rebooted
13) hotspot now works
I have no idea if this is hidden from the carrier

Fire tablet, block access to internet and delete some apps

I would like to buy a fire tablet for my son. I want to block its internet connection completely and delete all apps but office.
I saw a video here that one can root the system, but is it possible to do what I want and how do I do it?
Yes, you can do what you wish.
Step one, search for a thread on how to root.
After you have root, you can delete or hide whatever apps you like & install AFWall+ to block any app from internet access.
If you have not brought a Fire yet, or haven't connected it to wifi yet then be sure to check what version of the Fire OS it's running before connecting to wifi. If it's 5.0.1 then you want to block updates first.

You're going to have to better describe what you mean by that. Not clear on exactly what you want to do. You want to "delete the files of it". What is "it"? The internet?
How old is your son?
The actual programs which make it possible for a tablet (or a phone or PC) to communicate / send, receive information over the internet are basic low level programs which are almost part of the system. When people want to prevent access to the internet they use an app to block it. People don't look to strip out the basic low level programs. For a few reasons. 1) Most people don't know what to strip out, 2) it may have unintended consequences / break things, 3) it's unnecessary.

So how can I ROOT amazon fire tablet? I didn't find anything else..
Maybe I should buy a different tablet? the kindle fire is 39$ now.
I want to install google play and then, via google play install Microsoft office and some other small apps.
Second, delete google play and all other amazon apps.
Third, Block completely access to the internet of WI-Fi, not just pass word, I want to completely cancel the ability to use it.

Some routers allow you to block internet access per host. Sadly, that would only apply when at home. But might be an option worth looking into it. DHCP reservation / firewall rules.
