Thesis Topic - NFC Hacking

Greetings all
im currently looking for a thesis topic to graduate, and im interested in NFC
My supervisor asked me to prepare a proposal about the subject, he suggested that i choose an "application" or a certain aspect of NFC to study, i have an idea about maybe doing a comparing study about NFC Security techniques and methods, since one payment is probably the most famous application of NFC, however i cant really say that i know much about NFC, in fact i barely know anything about it, i'm a telecom student, and i'd appreciate if some of you can point me to some reading material or give me some pointers that wud help me preparing the proposal and eventually the thesis itself.
thanx in advance and best regards to all

Well since nobody else has replied to this, I'll help you out. NFC is short for near field communication. NFC builds on RFID systems that allows two way communication between end points. RFID was first patented in 1983. That's pretty general, I know a lot about NFC so if you have any specific questions I can help you there.
For more general information I'd recommend http://www.nearfieldcommunication.org
Good luck with your thesis my friend!
Just don't say you got help from a 15 year old...

Security seems to be a main concern this days. NFC advantages are aplenty, however no one is really concerned about the security aspect of it. i.e. hacking NFC or being able to track a person by their NFC capable phone etc. etc.
I would show that NFC can be easily read for instance passports, credit cards etc... Show the techniques used to circumvent reading i.e. hashing, pin codes.
In the end describe a theoretical approach that it can make nfc's security better.
In the end you just need to be able to defend your approach against other professors so keep in mind you need to be well aware of the subject.
This is my idea and this is how i would approach the subject. Im sure there are hundreds of other applications out there that you can ellaborate on.
Sounds cool though good luck.

thank you all
@Truitt.Jack its not a problem for me to get help from a fifteen years old, if you are good at what you do
who cares how old are you
@ Sofitos : thanks for the advice, i'll look into it

[Q] Implement Reputation System?

Hey guys (mostly the senior/mod/admin folks, but anyone feel free to chime in). Could XDA implement vBulletin's (I think there is an official plugin/option... I may be wrong about this though; I cannot say for sure since I am not an admin on any site that uses vBulletin, $user = phpbbWhore reputation system? If it's not built into the latest version of the code, I'm sure there is a 3rd party plugin available from VBulletin's official site (I know of at least a few of those that exist and would help if needed).
My thought behind this is that sometimes someone posts some really useful information and adding a reply that says something like "+1 thanks!" almost seems like a waste of a post to me (I really dislike "filler"/OT threads, but I still want to give the person credit). However if I was able to give a person a point (+) or if someone was just being a jerk for no reason (-), I think more people would take the time to think before they posted. Plus, since we know "post count" mean nothing in terms of someone being a helpful person or not, this would allow new users to spot trustworthy/reliable folks.
My only qualm is that I don't know if XDA as a whole is mature enough to use this kind of system responsibly, but I have faith that any real abusers could be weeded out fairly quickly. I think it would be cool to at least trial run this. Thanks for your time .
Hi DeeBG,
Yeah, it's good idea generally, thou i'd prolly advocate XDA going a step further right off the bat, and implementing a point trading system as a supplement to the donate buttons, especially for those without easy access to paypal credit.
Reputation has issues when someone on the fringe of the group is battered down for being different. Like imagine someone says "Let's make an iPhone section!". They might lose a years reputation in like a day. At least with a point trading system you're dealing with actual assistance or virtual services, rather than base emotional responses or crowd bullying.
I'm still learning about XDA's donate system, which seems fairly arbitrary or opaque. Maybe someone can explain how well that system is working out so far.
Cheers.
Reputation is built into vB, looks like they opted to turn it off. Good thing, every forum I've been a part of / admin'd, it's been abused.

The reputation system only works through "thanks", doesn't it? So your reputation cannot get worse, but only better.

It's not much of a system - you can donate directly to xda, which will help cover costs of running the servers, or you can donate to individuals (like me ) whose work you like.
Well there are really two types of systems. One is where you can give a thumbs up or thumbs down on a comment (sometimes represented by a [+] or [-] sign), and then there is the "Thanks" system, as seen on such sites as http://androidforums.com.
I agree that the first system can and sadly usually is abused (I think I saw it work well on one private torrent site I used to belong to a long time ago). There is a somewhat "pack mentality" that some users can fall into, whether someone is "outed" (falsely or not) for being an abuser of the forums or sometimes members are found "guilty by association".
I would like to see at least a "Thanks" system in place, again the folks at androidforums.com (which I'm sure at least some of you are also members at or at least have been directed to a post there before) have this successfully working within their vBulletin-powered site and would happy to help XDA admins if needed (not that I don't have faith in the XDA site owners/coders, you guys are pretty awesome yourselves =p). Of course I would be happy to lend my ~10 years of PHP/MySQL/etc experience to the process if it'd help.
I would start a public poll, but I think it's really in the interests of the site owners (also they can probably setup a more wide-spread poll than I can if they want public opinion).
Your friend in code,
DeeBG =)
I think it would be good to show appreciation to other users but It would be abused knowing that you can knock down someone's reputation (last thing we need is more flaming)

Yeah, that's why I think a system where you can ONLY give thanks would be cool. Again, forum admins, let me know if you need any assistance getting it up and working (it shouldn't add a performance performance hit to the backend database/system... the php code would be very light and the mysql db would maybe grow a few hundred kB since users without thanks wouldn't have any data).

Still open to cheating using multiple accounts to "Thank" themselves here and there and everywhere.
It's perhaps harder to gain anything with requests from yourself, and gifting points to yourself, while offering up public solutions. Thou i wouldn't put it past someone to try.

Hmm... There seems to be a growing trend on XDA towards "donation requests" or "developer bidding" in certain forums. (see Xperia x10 Froyo request topic for example).
It involves people collectively posting that they will each donate a small amount to their favorite cause. (Android on Samsung Wave being another good example)
The current running tallies of offered donations is also interesting idea, thou there is some concern that those who have offered to donate $10 or $20 dollars will actually do so once the developers have done their magic.
Again, the opaque or arbitrary nature of hidden donations is a problem here.
Without going as far as escrow payments system (for requests that could likely need time limits and a refund), a basic "pre-paid" point system should work pretty well. For instance, once a task is completed the points could then be traded back for paypal dollars, completing the "circle of trust".
Any other ideas on this?
(or is there already an active "services" marketplace here somewhere that i've perhaps overlooked?)

How much does the ads-developers site make every year

Hello,
I just want to know since there was a set of prizes worth $4 million that I think was being sponsored by Samsung how much does XT a development make every year? Obviously you are under no obligation to tell me since it's probably a private firm or maybe ohm by a larger firm. I only ask because most of the money this page because the developers store their hard earned software here and the forms that relate to them and they publish the results of their builds to these forums.
If I don't have quite right please still free to correct me. Please send a no circumstances at defensively and trying to lose your cool. We live in the capitalistic country thank God at least for now until socialism tries to take over. Or continues to try to take over.
Great Darlas I just wondered if any of the money was shared with the developers make the site possible. Are any or all of the developers actually paid by the proceeds from the site? Is any type of compensation whatsoever to the developers for their hard work that make some money that is generated by ADS that the owners of the site profit from? With just for now a set of $4 million in prizes I would think that the amount of money that the site generates is astronomical. By the way where do I sign up for these prizes see in all the videos?
If the developers are not making any money from this, G is the way that they can be made possible?
This is a perfect site for making money because of all the ads in the fact that people come here almost every day for a new set of operating systems to put on the phone, and that the source code from one phone can be used for many phones in general, well at least 60 to 80% or more. Feel free to correct my figures.

Btw your friends does not work very well with voice dictation
Especially with the program called Swype. Example if I
say period it's supposed to put a dot, if I say question mark it should put a?
I wouldn't complain except that you need your text boxes are extremely hard because we're you touch is not where the cursor goes. This makes editing impossible especially at the end of the line. As such ask for your patience because I'm highly disabled list nerve damage and it's very difficult to work your forums. It's not just with this keyboard software it is with others as well. Could you try to fix us as soon as possible

I do understand why this site exists period and I wouldn't be surprised that you actually make a lot of money orange that you barely break even . I am just curious to to know whether you make a lot of money are you barely breakeven. I only ask us because there was a set of $4 million in prizes being given away . Maybe that was just to third parties companies generosity. Does it hurt at all to ask these questions? /Can /will you answer them?
Also can you answer how I can sign up for the prizes?

Never heard about the prize so I am not sure. It doesn't hurt to ask although I am not sure this is the proper forum for it, and I am not sure why you felt the need to inject a political message into it, that tends to be frowned upon here as the site is about mobile phones and mobile phones aren't political.
As for your other questions, you might PM svetius. You certainly won't get an answer about finances posted back on a public thread, and frankly I doubt you will get an answer to it at all since you don't need to know it. I apologize if that seems rude, but this is a business like any other and is under no obligation or duty to show anybody anything with regards to finances except the owners.

Those are the only two questions I'm really asking. Is this a for profit business? And that's a subquestion of that I wondered if the developers work for this business or if they work as a volunteer project? I know that if this is a for profit business it would not exist except for the developers putting up their ROMs and other support here for the many users. I think it would be good if it is a for-profit business Khala that perhaps the business gives some support monetarily to the developers. Is there is a 4 1/2 million dollar set of prizes as it said in the videos, I would love to be signed up for that and I wonder where I can?
I just think sites that are built upon the developers backs or other people's efforts should give back to those people more then just hosting in their software if and only if the company is profitable. On this page alone I see there are three ads. The other side is if this is a business and it needs help because it's not profitable and we can help it then maybe we can give donations? As this is a very valuable resource it to be nice to know what condition it send financially so it
doesn't fail to disappear like so many thousands of other business over the last few years.

The prizes in that competition are provided entirely by Samsung.
If it's the same competition I think you are referring to, you would need to publish an app on Samsung's store, and the most popular apps on a given date win...
Regarding developers, we have introduced a program recently to give a small number of developers phones and tablets to develop with. This is still a relatively small program, but I'm sure with time it will expand a bit, in a controlled manner

BTW for typing via swype, have you considered trying the XDA app or Tapatalk? Much easier to use, as it's a native android app...
For the punctuation, I think that is a restriction of the voice to text software used within Swype, which I think is provided by Nuance.
I suggest you start typing your posts like everyone else if possible. Your voice dictated ones are horrible. They remind me of the kind of garbled messages spammers send or the garbage that results when lazy spammers scrap content and put it through an article spinner. Either that or get some decent voice dictation software.

I'm curious were you in a bad mood when you posted that, or were you just lacking enough charity to have any responsible foresight?
I use voice dictation because I had a bad operation which left me with severe nerve damage and muscle damage and muscle atrophy throughout my upper body; I am in moderate to severe pain about 24 hours a day even while undergoing pain management treatment. I used to run a worldwide software development organization with world-class developers for governmental programs. Forgive me if voice dictation is being my arms for now, and most likely rest my life.
But please if you can recommend voice dictation software better than Nuance on Android please do tell me about it. Google is still a large leap behind. I do not know of any others, do you? Perhaps this is a calling for you to write one to help many without the ability to type. What languages do you know? How proficient are you at programing? What is your background and education? I'm sure I can touch base with some of my old research buddies in the government who would love your donated time for such a project, if you have any programming skills or development background or even research background in linguistics, speech algorithms, or other related technologies.

I suspect she is a teenager. There are quite a few here.
I don't know of any other voice dictation software, sorry. Never had a good opportunity to use it so I never investigated any of the available packages out there personally beyond a guick google once. Actually your posts were not any worse than many of the ones I read by the teenagers here with their abbreviations. :-/

We need an NFC revolution!

Hey all!
I love NFC, just as much as you - seeing as you're reading this in the NFC section, I assume you use NFC regularly. I think it'll be fantastic when it's main stream, however for it to become a truly mainstream it needs more data type. just like you get vCards, URL's, SMS's etc - I think we need more help from Google, Microsoft and all the hardware vendors - along with the NFC forum itself - to help extend NFC's capabilities.
Sure we on XDA know how to extend it's abilities - either by hacking it or knowing which app lets you do a certain additional function. Unfortunately normal members of the public won't know about the XDA way or about the apps. For example the problem is you can write an NFC tag to connect to a a device to a particular wifi network, however you need the app that wrote the tag or another app that understands what to do with the tag for it to work. Now the problem is that your guests probably won't have the app installed, so you'll have to connect them manually or download the app over 2G/3G/4G and depending on network strength - just like my area - could take a long time!
What came first, the chicken or the egg? What came first the wifi or the adoption of more standard / capabilities, across OS's / vendors ?
There are plenty more examples, but this is the most useful and self explanatory I can think of.
Please, please, please read my blog post about this and if you so wish, sign the petition, message the NFC Forum telling them to get their butt's into gear - message Google and the Android dev's do what you can to make NFC better and help it's adoption :good:

As much as it pains me to say it...we need Apple to implement native NFC support in iOS. I was really excited to see Passbook (or whatever its called) and was nearly positive this meant NFC support for the iPhone 5. Unfortunately, not this go round. It's ok though, wait a couple iterations of iOS/iPhone and NFC will finally be deemed acceptable for the public...magically...revolutionarily.
I know, and I think why the heck should we wait? Apple might only bring NFC with the iPhone 7. What's the harm in trying to change it now?

Yeah, they need something the can control - they need to devise a way to make money out of it otherwise it's not in their interest.
I know this is XDA Developers and we can make NFC do what we want, but we all have people in our lives who won't even use NFC because they don't know about it or know what it can do which is why I'd like us to make a change at the OS level on behalf of all of our non-technical friends and family. Let's get the big players like Google, Microsoft and anyone else that's already using NFC in their products to want to make a change - for Grandma
Lets be honest guys, the majority of people around us have iPhones, mainly 4s's. Imagine if all of them had NFC and we could all play nicely sharking playlists and sending phone numbers to eachother?

NFC is the next big thing just give it time. once it rolls out. more in new devices we shall see. it's development grow more and any phone worth it's salt will have to have it
I agree - a revolution. Right now, when I mention NFC to most people they give me that "HUH???" expression. Then I have to explain what it is and then I have to give them examples of what it can do. Seems like almost no one knows what it is or has any idea all the cool things you can do with it.
What we need is a Samsung or Google or HTC to run a commercial that features people using NFC - with tags to automate stuff at home/work, with Google Wallet to pay for stuff, other things. Then the average person would be like "oh I know what that is - I saw it on a commercial"
Unfortunately right now it seems like it's just us tech geeks who know about it...

How much data can actually be transfered via NFC? I always thought the bandwidth for transfers was rather small, which is why most items transfered are under 144 bytes.
For larger transfers wouldn't using NFC for the handshake then Bluetooth for data transfers be better?
Sent from my EVO using Tapatalk 2
I have to admit I am one of those people who do not know about its capabilites. I know what it is and have it activated on my phone, but what can I do with it...I do not know besides I think you can tranfer pictures, phone numbers and stuff.
Can someone maybe explain it in more detail and tell us about its uses? Maybe I should have done a search about NFC (Near Field Communications) before I wrote this.
P.S. I wish more people would put the acronym meaning after the acronym, like I did above, in this forum...ooh that gives me an idea!! (light in head goes off!! lol)

How much data can actually be transfered via NFC? I always thought the bandwidth for transfers was rather small, which is why most items transfered are under 144 bytes.
For larger transfers wouldn't using NFC for the handshake then Bluetooth for data transfers be better?

I cannot tell you if there is a limit in filesize, but since the biggest NFC tags you can buy at the moment (afaik) are 8kb, anything beyond 1mb is most likely to take to long to be economic.

[Q] Fire TV. HDMI to VGA converter.

Hi this is my first post. I'm looking at buying the Fire TV stick but my TV has no HDMI socket. My TV is a Panasonic Viera TH-42PE30 and I'm wanting to know what converters will work with this TV and the fire TV stick. I've been told that some converters haven't worked for some people. Any advice/help would be greatly appreciated as I'm looking at purchasing both the fire TV and the converter together.
They make HDMI to DVI and VGA cables should work fine. That's how my PC is running at the moment HDMI out of video card to DVI on my monitor. The HDMI port went bad
Keep in mind that there might be problems with the HDCP copy protection of the HDMI output. If it´s activated within the FireTV many converter may delivered only a black picture on VGA.

No comments about quality, because those things have to do a signal conversion. Its not a simple "cable", all of them are doing signal processing.
Also you might run into problems with HDMIs copy protection.

So do you think both of those might work?
How likely do you think it is, that I spend the 10 dollars and the effort of hooking up the Fire TV to a VGA port, just to figure out which parts of the video output amazon encrypts with HDCP?
Also - there is a hint in there what you should google next to find out how android devices usually are set up in regards to a certain form of copy protection.
Or you just spend the 10 USD and then come back to tell others - highly unlikely concept, trying something and then reporting back... Nobody does it on social platforms today. Not enough upvotes. people care about the occasional insight into a field, because it makes them feel like they are diverse in their interests, but really, the second time around, it already feels somewhat old. Ask into the aether, wait for the Answer to come back. No filter, no quality control, just random noise. And if you feel like you really want a more valid answer, just venture out and try to exploit a tech community. XDA made a video for this demographic once.
Also, just as a tip - there is a reason that I cant tell how the image quality on these things would be today - even in third world countries - and I mean this in no way demeaning - the proliferation of HDMI enabled TVs is high enough that they start to reach lower income households. Thanks to offbrands. There is absolutely no market anymore for those converters. Thats why they now are in the 10 dollar impulse buy category.
Now you want buying advice on that... Ask your walmart sales rep often which 10USD coffee is the best? Ask some one who worked at those specially retailers, who now go bankrupt, because they were in the business of hiring people who understood what they were selling first, and were salesmen only after that? Then buy it on amazon. You know - the difference between Rhine capitalism ( http://en.wikipedia.org/wiki/Michel_Albert ) and whatever form americans are living in contrast to that today.
The economy in an internet forum is really not made for such requests. You bring nothing, you've invested nothing, you take value, you learn nothing that would prevent you from needing personal treatment the next time around, then you repeat the process whenever another need comes along. You exploited others when this still was a job they were paid for by companies - now you are exploiting nameless random people on the internet.
Face it - at least to some extend. Or be happy with the "there be cables" answer, because - there is no middle ground. The economy to provide you with informed and detailed answers simply does not exist.
Do something for yourself, show engagement, search before you ask - and dont fake it, because it just makes you a person who now knowingly abuses others for their benefit.

I can sum it up for you. Just buying a cable that says HDMI to VGA will not work. You have to actually have a converter. Converters for what you are wanting to do usually cost around $40 minmum. The cables are usually used in conjunction with PCI type converters. PCI type converters will not work with the Fire TV since they only work with PCs, so you will need a converter that plugs into an electric outlet.
Actually - I learned something today.
I learned, that amazon.com now does freely sell devices that strip HDCP out of the signal into the american market. Which of course is illegal.
So search for hdmi vga dac hdcp
and read the product descriptions and or comments.
Whatever those boxes cost, they cost 16+ USD from an asia based vendor. Also - because they are this cheap in production (it doesn't count that some vendors sell them for tripple their price), your monitor better supports 1080p natively. With the correct scaling (picture not squished or cut off) and everything.
According to a german amazon post by a customer who talked to their technical support, the FIre TV (not the stick) needs at least a HDCP 1.3 compatibility - at least this was suggested by an answer regarding potential sound issues.
So whatever device you end up buying in the end, it should have the ability to strip HDCP 1.3.
Also - Im suddenly much more forthcoming, because I accidentally, initially provided two links to devices that will not fit your questions profile (just looked for the right connectors (male/female), didnt read that they still werent dac (Digital to Analog converters - which is what you need)) - so I'm in "making good" mode. Because if you are talking as harshly as I was, imho you have to be correct down to the last details.
Wow, thank you all so much. I'm not really a tech guy but I can tell you I'm very appreciative of all the information provided. I will have a look at some converters and let you know how I get on. Thank you again
Its just a very unfruitful question - because the real answer is "buy something that has a HDMI port, everything does - nowadays". The followup answer is, to achieve this your way, you need something that converts the signal. Which is not just "buying a cable" - this thing has to have a chip in it. The follow up answer to that is, that those devices commercially only make sense anymore, if they are dirt cheap, which might lead to signal quality issues (also, potential scaling issues).
The next problem is the copy protection layer (HDCP 1.3) which has to be removed so you can even convert the digital HDMI signal to analog VGA. This wasnt always possible. Also - I would not openly talk about this information, if not amazon themselves were suddenly selling those devices in their store. So I'm choosing just not to share links.
At which point you also have to take into account the different versions of HDCP (because the industry doesnt like broken copy protection standards and writes new ones) and which one you have to circumvent.
And what for? First - copy protection at a point in the signal path, where currently only game streamers rip anything. And second - all that for something that increasingly even woulndt be an issue anymore in third world markets. Because everything nowadays has a HDMI port (- supporting or stripping HDCP). So this is all theoretical, and practical for almost no one in here. Which is why "should I buy this one, or that one" is even harder to answer.

I appreciate its not easy to answer but thank you for trying to do anyway. You've really helped me out so thanks! I'll be sure to let you know how I get on.
Does not work. Tried it. You need a converter that has its own power source, cable or other so called converter powered by USB will not work. You need something like this:
http://www.amazon.ca/gp/aw/d/B00AQMZI0Y/ref=ox_sc_act_image_1?ie=UTF8&psc=1&smid=AGP6GC0L2FALW
Most cost effective one I've seen with good reviews.
I'very tried a few others that have not worked which is why I'm confident in what I'm saying. Good thing about AMAZON, hassle free return if it doesn't work.
To reiterate again, I wouldnt have answered the question properly, If I hadn't indadvertedly messed up and linked to two wrong items in the shortform statement. (The hints toward solving the problems were right, the links were wrong.)
I dont care how much this helped your case specifically . I simply dont accept a simple line of heartfelt gratitude as "currency". Is it decent - sure. I'm just not motivated by it at all. Not before I read the question, not after the fact.
And if you feel the need to emphasize your gratitude again I have clearly done something wrong here - my motivation was to show, that it is not ok, to drag a picture perfect example of an egoistically motivated request into a public forum, without any research or intellectual investment on your part - and then expect a short solution delivered to you on a platter.
The investment of people who are clued in is so much larger on their part, and is almost solely concentrated on you personally - without any chance, that this will help many others, that it becomes necessary to demand work from you as well. Not gratitude. You acquiring information yourself and therefore rethinking the approach of exploiting the community.
This goes differently, when a community is highly active and you have many people reitering the snippets of information they just learned and helping each other out, because it is encouraging for them. Which is by the way what support forums sell to advertisers (Context matters).
See the difference in the approach, see the resulting difference in motivation.
If you dont want to learn or reciprocate yourself - do what the last poster did, and exploit a company that factors in consumer support/returns into a business model. That way it can at least be measured by capitalism as a social structure.
What you are doing is effectively destroying social structures. You take all efforts that go into problem solving, and give back no value in return. Again, gratitude does not count.
And by the way - you are lucky and in the end some one else had the very same problem and had to solve it for themselves. When they have done so - they put in the work for themselves (in this case by exploiting a companies return policy), and sharing doesnt take much effort on top of it. But looking for others to solve your problem - not parts of it, just the problem entirely - is a different animal. My motivation then is to first refute the false answers that come out of the "well I dont care who..." "well I dont care so much about how either, but I have heard" exchanges that follow. At the end of which no one even cares so much about if its factually correct or not - or even to mention the outcome.
I made an error at that stage.
And this is the only reason, why I have become this active in here - because suddenly it potentially impacted my reputation negatively.
The problem with information ecosystems is, that information nowadays is practically free, but filtering and researching it - is not. Always try to remember that.

I'm not sure who this is aimed at or what you are trying to say. My gut feeling is that you're offended that I asked for some information to something. It was merely a question that I asked. For your information I have done a lot of research but am not the most technically savvy person when it comes to this. Why some people feel the need to have knowledge and not share it is beyond me, but that is your choice.I thanked you for your help, just as I have everyone else for theirs, accept it or don't, that's up to you. I did not intend to offend but am thankful for the help I have received
I agree with the post above, maybe you have too much time on your hands.
I'm using this one, you can extract the sound from the HDMI too.

Wow I didn't think anything like this would work. I have an old Panasonic viera so I'm hoping something like this might work as would be a lot cheaper that way. Thank you for posting:good:
>Wow I didn't think anything like this would work.
If you had read amazon reviews, you' have found out that some of those models strip HDCP as well. Just saying. They advertise it as "compatible with DVD players, Playstation 3 and XBOX", because its illegal.

Was there really any need? I have read reviews about this so stop making such a big deal about this. People are trying to help, yet you seem intent on making out what I've done is wrong. Nobody else has reacted like you, I suggest you don't post if it annoys you so much
Yes there was a need. Focusing on the form factor is harmful, when more than half of those adapters (same form factor) dont strip DHCP from the signal.
Linking to certain ebay sellers or product rebrands is solicitation. Also ebay auctions are gone within a few weeks which might induce the search for similar looking models. "I never thought it would be possible within this form factor" - without context - is drawing potentially harmful conclusions that others could copy and end up with non working devices.
Those are two reasons why It was necessary to break the focus on form factor - and focus on the stripping DHCP part again. As far as price point is concerned, 16USD from some sources also was old news. (This one is 10 USD with no mention of DHCP stripping in the product description (could still be in it) and one anonymous recommendation from someone on the internet.)
This is enough for me to feel the need to become active again.

Is there any way to get Gear VR working again without rooting?

I've tried using Google Cardboard with the Gear VR headset and the results are not great - nothing like as good as with the Oculus software.
I know you can hack it to get it work again if you are rooted, but I am not. Is there any other way?
I have read many of your posts Chippy_boy and I doubt I could dissuade you but for the sake of anybody else reading this thread can I point out what a really stupid idea using any VR device with a Note 7 is. Does it really have to be said?
I'm sure nobody needs it pointing out that this is a device that has been withdrawn by the manufacturer at enormous expense because it has a fault that causes it to catch fire in spectacular fashion. And before people start posting their home brewed calculations of the risk, NOBODY knows the risk of this happening in the future because you have NO information what the fault is and therefore the future likelihood of failure.
<Mod Snip>
Tom, perhaps you mean well and thank you for your thoughts on this matter.
But have a think on how many Note7's have been shipped. And how many have caught fire in a GearVR headset, i.e. none.
In fact have another think on how many have "exploded". Also none.
People can make up their own minds about how dangerous or not this might be, but thanks anyway.
Let's keep things respectful please.
Thanks!
:good:
I think, in my opinion, when somebody asks for help about some topic, if anybody has an answer or idea as to how to help, that person may choose to or not to help, but please, dont try to convince or educate others, to do what you think must be done, help if you can, thats all
rooting is likely the only option outside of cardboard. unfortunately in the situation there is going to be very limited new development for the phone.
