why do only some wifi tether apps require root? - General Questions and Answers

I'm asking mostly for knowledge- I'm rooted on the e4gt w/ jb goodness. My boss was looking to wifi tether on his wife's phone w/out rooting and he found an app that does it claiming that no root is required. Why have apps traditionally required rooting for this (if this is true and not a false belief of mine) and what is the difference between wifi tethering apps with and w/out root? Thank you.

Those that require root actually tether your wifi, while the no-root apps probably use the phone as a relay between the PC and phonr

[Q] Non Rooted Verizon Galaxy Nexus wifi tether question

Was just wondering if anyone knew what if any repercussions there would be using the Wifi Hotspot and USB tether app from SVTP (from the Android Market) on a non-rooted Verizon GN. The app works great and was quick to setup but I am interested to know if I will be automatically popped into a Mobile Hotspot plan (which I do not have now) if I use it.
That being said would it make more sense to root my phone to circumvent these potential charges?
Any help would be much appreciated.
Thank you in advance.
Verizon has recently adopted new changes in how it monitors for tethering and when unauthorized tethering is detected it redirects you to a verizon web page on how to order a tethering package. I have heard PDA net still works, you might want to check out Koush's tether app, reported to be undetectable.
I say either way root your phone, then load a custom rom many of them have work arounds for wifi tethering

NS4G: Tether on stock ICS rom without hotspot monthly charge?

Yes I am a newby. Yes I have searched and didn't really find what I was after.
I unlocked my phone a bit back and did the leaked IMM26. Since then Sprint has updated it again to 4.0.4. I now have an Asus Transformer Prime with ICS and would like to use WiFi or BT tether on my NS4G. Is there a way to do it without going the route of loading up a custom ROM?
Thanks in advance for your time and assistance.
Cheers

I have tried wifi teather. The tether function itself works beautifully in ICS. The Prime gets its IP address fine but there is no data connection. If I open the web browser on the Prime it states there is no connection. So either I am doing something wrong or its still locked out by Sprint in ICS. Help or clarification is appreciated either way.
I have also tried the "1-Click WiFi Tether No Root" app from the market and it does not work either. The problem statement is if I tether with the native ICS or with this app or others in the market then I lose data connection on the NS4G and obviously dont get it on the tethered device (Asus PRIME in this case).
After a considerable amount of reading I decided to just root the phone and install ClockworkMod and vhgomez36 ICS 4.0.4 ROM. Why? What I discovered is that even rooted there appears to not be an app or way to Tether when using a stock Sprint ROM. They disable it and check your account settings at launch to see if you have "Wifi Hotspot" enabled. If you do not then they disable data on the phone.
Works great now on vhgomez ROM with stock ICS tether app.
Case closed.

[Q] How to Bypass T-Mobile tethering restrictions

I know there is at least 1 method for bypassing T-Mobile tethering restrictions for the Nexus5
For example: This thread ( http://forum.xda-developers.com/showthread.php?t=2512674&page=8 )
However, are there any other simpler methods that don't require rooting your phone?
T-Mobile's unlimited data plan includes unlimited data for the Nexus5, but not for tethering. T-Mobile gives you 2.5GB tethering hotspot for free, so you can use your Nexus5 to tether. But it appears that not even apps like FoxFi help when you've reached your 2.5GB tethering limit.
I used my Nexus7 tethered to my Nexus5 yesterday, and when i went to a chrome webpage on the tablet, it prompted me to upgrade my tethering plan....
I was stunned.........
First) because I didn't know T-Mobile could track tethering on a Nexus5......... and I still dont exactly understand how they track it...
Second) because even if they could somehow track tethering, I assumed that since I was using another android device, they wouldn't even be able to detect the traffic difference between Nexus5 and Nexus7
Third) because FoxFi didn't work !
Are there any methods (similar to FoxFi) that work? or are T-Mobile tethering restrictions unavoidable unless rooted?
Based on my understanding, Google built something into the Nexus 5 that reports tethering back to the carrier. It's unfortunately but certainly understandable as I'm sure the carriers have been asking for it for a while. The reason this breaks FoxFi as well is that FoxFi seems to use the built-in tethering with a hack to mask traffic. Since the built-in tethering is reporting it as tethering to the carrier anyway, masking the traffic doesn't help.
The modification to settings.db appears to disable that reporting with a single value, a setting that is obviously not normally available to the user. Since apps like FoxFi have been able to use the built-in tethering to work around carrier restrictions in the past, I think you will need to see development on a new app (like the old Wireless Tether for Root Users that predates the built-in tethering) to get around the restrictions without modifying system files.
What bothers me more is that my plan includes tethering and I am still hitting the paywall on my Nexus 5.
Any updates to this?
I have the $20 unlimited and unthrottled 4G data add on, it comes with only 2.5GB of tethering, then I get the upsell message.
try this link
http://forum.xda-developers.com/showthread.php?t=2581035
Pretty sure that they check more ways than one. They did ask Google to put in a checker (found in the changelogs for official update) but also they check via the header of the packet of info that passes through their towers. Some have had success with just changing the user agent of their browser, but if you are completely stock then I think you have to edit the framework, the sqlite option, and the browser agent. Might be easier to use a custom rom that doesn't have the framework stuff in it. I don't use Tmo anymore, so can't test this stuff out. When I had my S4 on Tmo, I had to use a VPN, custom wifi tether app, and only then could I tether without being sent to the upsell page (my plan at the time did not even include tethering either).

How Do I Spoof WIFI So Apps That Require Wifi Will Run?

I have a Samsung Galaxy core prime on metro and want to use my data vs wifi, I have no wifi where I'm at due to having hotpot on my cell phone. I have multiple apps that require wifi only to run and I want to trick it in using only my data connection. the posts I have seen require root, and I have yet to see any solid proof that this phone can be rooted. Any suggestions is appreciated.
