At my college dorm, we use a certain type of lock in which we put our keys up to the lock, and it unlocks. I figured it used NFC, but I wasn't sure. Then I found this article.
androidauthority/forgot-your-olympic-hotel-room-key-use-your-s3-103325/ (NOTE: As a new user, XDA won't let me post outside URL's. Type in .com after droidauthority for the link to work)
I've got no clue what kind of hardware is in those locks, but I can say that it looks EXACTLY THE SAME as the locks used in my school. For me, that essentially confirmed they use NFC. I don't know who makes those locks, but my school uses the same looking handles and lock mechanism. When the card is held up to the lock, the lock flashes green. If I had to guess, the card acts as an NFC tag. When held up to the door, it will activate my card as any other NFC tag, verify it's me, and then let me in.
Using NFC on my phone, I was wondering if it was possible to do the same! From a logical standpoint (not a dev's standpoint), I would need to somehow steal the info off my card, have it stored in my phone as a usable format for the lock, and then I should be able to just hold the phone up to the lock to have it open!
You guys think this is possible? How would I go about doing it?
sorry that i don't have the answer, but i had this same idea! also wondering if it's possible.

I dont think these use the same frequency. Here in my office we use the HID Prox cards, but its not the same, the easiest way to know if you could do this is get the NFC tag reader software on your phone and try to read the card/key if it will see it I would think you might have a chance, if it doesnt see the card to read it, its not the same and you will not be able to do this.

from what i've read...
doing what you're suggesting would pose a major security threat to all electronic door locks around the world. you're essentially duplicating your electronic key, which is not unlike duplicating an old school lock/tumbler key. unlike a traditional key however, this is an electronic key which means if you're able to duplicate it, you're also able to send/share it with friends around the world. in other words, we can set up a database of all the dorms / offices locks around the world and we can all have free access. doesn't sound like a pretty picture.
in reality, what our phones are capable of doing is READING the NFC tags. so if anything instead of thinking of your phone as the key, your phone can do the exact same thing as the lock, which is read the info off of the NFC tags. i know we have the ability to WRITE info onto NFC tags as well... but as others have posted there are issues of frequencies and i believe encryption which I HOPE makes this not possible for my security sake.
I'm sure if its physically possible(frequency wise) someone will make it happen. Its just like droid sheep, air crack, wifikill and the likes. Doesn't make it right but throw the technology out there and someone will make use of it.

I was able to do this with bluetooth and my Samsung Note 3 on Windows7. Got windows 10 and *poof*, it's gone as a bluetooth service. Now I'm scratching my head trying to figure out if that was a function of the BT dongle software, Dell security tools, Windows 7, or what!? A little off topic (not-NFC), but I have the same functional objective.

This is a question for those in the know when it comes to programming.Why isn't there a way to revive a bricked phone? Can't there be some method for a host computer to manually write the radio to the device? How does HTC fix a bricked phone for it to be a refurb?
I'm just very curious about this because I see a few people attempt to update the radio only to lose power and brick their EVO. I have no programming experience so don't know what goes on at the internal component level. Thanks in advance for your input.
It goes back to the old bootstrapping problem when computers were being developed. A computer (in this case, your cell phone) is pretty dumb at the hardware level. All it can do is run programs. That's ALL it can do. It can't even load a program, only run them. Thus the problem. It gets solved by injecting a "bootstrap" program at startup (from the phrase "pull yourself up by your bootstraps") which is a program that runs and gives access to all the I/O, and the computer can then load more programs.
When you update this bootstrapping program, it gets dicey, because if it isn't written right, or if there's a glitch during the update, this most basic of all functions gets corrupted. If the program that tells the phone how to load programs goes away, all the phone can do is... sit there. Like a brick.
Hope this helped!
That helped me, thanks.

Thanks for the info. That is interesting. So how does HTC initially put the bootstrap in and/or how do they handle a bricked phone?

There is probably a JTAG interface somewhere in there. In fact,that's how the original hack of the IPhone was done. (Better ways were since found) Most devices have a quasi standard interface for programming the flash and accessing and the hardware for diagnostics. For instance,linksys routers actually have a spot on the board to solder a header and you can make a cable that connects to the parralel port. Do a google search for "Hairy Dairy Maid Debrick" and you will find it. A similar thing is probobally possible with the Evo (Ive even seen them on Hard Drives and CD Rom drives) The problem is,its not entirely standardized,and it might not even be a connector or pads on the board. It might instead be a matter of knowing where you can connect the leads on the board to something that under the right circumstances BECOMES the JTAG connector. (For instance,a pin that controls something else might be a JTAG interface for the first few hundred milliseconds of start-up,or if a certain other pin of the chip is grounded when the power is applied. It might also be completely internal to the chip,and there be NO connectors on the board (it almost CERTAINLY has the capability,they need it during prototyping) and the chips might be programmed BEFORE they are soldered in. It might take replacing the rom chip to get it to go. There are lots of ifs
Chances are though,the factory has a special cable and a special software program that can reprogram the device. To replicate that might be relatively easy or could be next to impossible but requires a certain degree of knowledge about the hardware. What I suspect is,until someone who has the skills to make such a cable bricks their phone,they wont bother figuring out how to debrick one. In fact,when that person bricks their phone,they will probably take it back to sprint and say "I dont know what happens" In fact,even if its stuck looping in an obviously hacked boot loader he for some odd reason cant undo,hes probably going to send it back to sprint. I know someone who did exactly that to their brand new HP laptop. He found that 15kv from the flyback of an old B&W television applied to the memory slots took care of the looping and Best Buy gave him another one. As he put it "I dont know what happened,but it smells bad and wont boot up"

Yea,it would be nice if it were. Its kinda sorta quasi standard,so it HAS been done in some cases where its necessary,but often there are easier ways around it. Personally, I have allways thought that its a pretty stupid thing to make a piece of equipment that can fail due to a bad flash. The people who designed many of the flash memory chips seemed to agree,and they added something called a "boot block" to many,but the way its implemented,when its implemented doesn't fully protect you from a bad flash. Its even worse now that everything is in ball grid array chips soldered down to the board.
Hey everyone, I'm looking to see if there's a better alternative to wavesecure. I was robbed last night at gun point and among my DSLR cam and wallet, my phone went along with them.
That is when I realized how useless Wavesecure is. I don't know who's paying for it since I got in on the free lifetime membership but what a waste of money.
They completely ignore what happens in a robbery.
First, phone gets stolen and turned off by thief (if they're smart or been doing it for a while).
Second, Victim tries to lock or track the phone through the Wavesecure site but with the phone off..nothing will get through. Sure, you may say, "as soon as they turn it on...." but how long will you wait? The only way this will work is if you can get the wipe command in soon enough. Otherwise, if you lock it and they see it...off it goes.
Third, after the police report.. you start calling the bank.. and eventually sprint to restrict service. But if you restrict it then the command will really never get through unless they're on wifi.
After you restrict it, it's time to say good bye and Wavesecure has done nothing.
The best security measure, is to have a weapon of your own, haha. Or maybe lifting the ghettos out of the ghetto so crimerate lowers, :O.
Seriously, the thing I appreciate most about the phone is that I had it pattern locked. So if it's off, then next time they turn it on, service or not, they'll be greeted with it. So, no access to my data, which is the biggest loss for me. The only thing vulnerable is my microsd card...which is why wavesecure let me down. They will never connect to wifi because they can't unlock it and sd card will never be wiped.
I'm glad I'm on a CDMA carrier, esn blocked. Nothing like that on GSM that I know of.
Is there a solution that will wipe your phone AND sd card after a set number of failed pin/password/pattern unlock attempts? Say 20?
Funny info: they only used my credit card once. $2.20 at a McDonald's.
Yes: There's an app called "autowipe" which allows you to wipe both the phone's memory and SD card if one of the following conditions is met:
1) Phone receives a text with a password in it.
2) User-defined number of lockscreen password failures.
3) SIM card is changed (doesn't apply to us, but nice feature).
Best of all, it's FREE.
The number one thing is that you are ok, these fools out here will shoot even if you cooperate with them. I ran into a similar situation with my phone (not robbed) but my phone was stolen and I had mobile defense. Only way to track the phone is if it was on which the thief turned off, so the only option was to wait for them to turn on the phone, which I did attempt for a few days but lost hope and had sprint stop service to the phone. The only option I had left was if they turned on the phone and connected to wifi which had not happened to this date so I had to buy another Evo which was equally painful as the first one being stolen. Like I said though, glad you are ok because a phone can be replaced, not a person.
Autowipe, darn. I hadn't heard of it before. I never really thought out the situation. Noone ever expects to be in it.. First thing installed when I get my phone from asurion.
Jfree, no insurance? Buying one full price is the worst, to top it all off. I was skeptical about needing insurance. I had never lost a phone before..but stolen never seemed like a real possibility. Always a surprise.
Autowipe seems like the app i was looking for. Definitely a must have, especially to protect all your valuable data.
That sucks, Los Angeles really does suck... thankfully I am in the northern half of Cali
Sucks.

So you do not like wavesecure because it doesn't work with the phone off?
Find out what McDonald's they went to and get the police to pull the videotape at the time of the sale. Have the LAPD do something for a change.

I didn't say I didn't like it. I'm saying that in the situation for which it is intended to be used, it is useless. Autowipe and a pattern/pin/password lock would be a better alternative. Especially since you have to pay for wavesecure.

Why would it work with the phone off? It has no power source. No power source =/= signal. Now, once they turn the phone on you are good..but no matter what you do to your phone (short of planting an actual gps chip on it) it will not work if the phone is on.

Not once did I say that I expected it to work while off.
Did you not read? My argument is that by the time they turn it back on, non-predictable, the phone will have already been restricted by you..but at that point you already don't expect to get it back..
I'm originally from S.F., but I moved to LA for the crime.
i am sorry for your loss sir.
Thats why I believe every person that does not have a criminal record should be allowed to have a concealed weapons permit with training...if these punk ass lowlife pieces of **** were afraid they would be killed when they rob or attack somebody maybe they would think twice...i guarantee crime rates would drop practically overnight! But the damn yuppies and politicians only want the criminals to have guns..
Sorry man....that sucks. One of our employees just had his stolen out of his car which was parked in his garage. Had Lookout on it and I was able to track it for just a few minutes while they had it on but couldn't pinpoint the location before the phone was turned off. After that, called Sprint and shut phone off. Bye Bye phone.
Looking back on what could have been done......
First thing, set an unlock pattern for your phone so, unless they know how to bypass, not going to get into it.
Second, even if the phone is off/locked they could pull the SD card and browse via PC. If sensitive information is on there they will have access. There is an app in the market which lets you set a password for any folders/files on the card you wish. This way, no access granted to those particular items.
If you want the app and can't find it repost and I will dig it up.
Also, Sprint will give some credit for the phone if stolen but with what they charge it will still be expensive. Might be better off buying on sale over the net for cheaper price. EVO was advertised on Amazon not too long ago @ 99.99.
I used these searches before compiling this thread;
"how to recover data from a bricked SGN"
"data extraction from a SGN that will not boot"
"removing the HD from samsung galaxy nexus"
These searches did not yield results that replicate my situation. The only search that resulted in many entries were for people with "bricked phones" that (at least somewhat) responded to input. I associate the term "bricked" with a phone that does not respond to input, or show any indication of getting power.
My phone is a Samsung Galaxy Nexus on verizon wireless. It has been rooted and is running a custom ROM by...AOKP i think. I had some assistance each time I rooted and updated my ROM.
Here is my problem, what caused it,my troubleshooting steps, and what I'm trying to do. My phone was partially submerged in water for an unknown amount of time. The battery and SIM were removed and kept in a water proof container within an hour of submersion. The water damage indicator stickers (on both the battery and the phone have not been triggered). About 24hrs later, the phone was placed in a zip lock bag with 4 desiccant silica gel packs where it will remain for the next 24. Per vzw's tech support, I tried to power the phone on using the charger and the battery removed. No change. Verizon was not advised of the partial submersion, only the non triggered water damage stickers. This phone is under warranty and a replacement has been shipped. I confirmed that my contacts are backed up to google.
The reason for this post is, I have close to 30GB of pictures and videos that I stored on this device's "internal SD" that I want to recover. Looking through the searches I mentioned above, it sounds like this isn't so much a separate card, but more of a partition on the phone's HD. I have been told by vzw that neither their branch office tech support, nor their recovery/diagnostic team that analyzes returned phones has the capability to remove and return this data.
If someone here has hardware experience with cracking open a SGN and swapping the "internal SD card" I would greatly appreciate any information available for this task.
if it cant turn on, you cant retrieve data.

Well..OK. I'm not ready to give up just yet. When my desktop PC's power supply failed, the PC was unusable, and didn't indicate power. I swapped that out and it now it works fine. This seems like it could be a similar situation. I at least want to exhaust every option I have before throwing in the towel.
Those 30GB contain hundreds of pictures of the first 2 years of my kid's life.
It seems to me that data recovery should still be possible if an replacement power source is utilized. Maybe more than just the power source has failed. Maybe every other hardware component in my wet phone has failed. But maybe, that "internal SD" is recoverable.
If anyone here knows what the "internal SD" looks like, and has successfully swapped one, I'll risk it. I know I can't trust vzw with such a task.
I realize this is a developers forum, and I'm asking for hardware failure advice. If anyone can refer me to a different forum that is more specialized to my specific task, I'll gladly take my trouble there.
Thanks for reading,

you're assuming 1 thing. the nand that houses the storage is in good health. When water is introduced, you have the unknown factors of what it does to circuitry.
im sure there is a ifixit teardown showing where the nand is. The problem is its soldered to the mainboard of the phone. You might be able to unsolder it, but thats a stretch.

Thank you very much Zepius. I googled "ifixit teardown samsung galaxy nexus" which lead me to a page (that I'm not able to paste here as a new user).
which is exactly what I was looking for. I wouldn't go so far as to say that I'm assuming the nand is in good health, just wishful thinking.
Anncoco - sorry, I don't remember what I did with this. It's been about 4 years, and this was 3 phones ago. I think I had some of the photos backed up somewhere else, enough that I never went to the trouble to disassemble the Nexus. From my notes - I remember the phone did not indicate it was getting power when plugged in.
Last night I finally setup android pay and thought I would use it on the bus this morning. I tapped and tapped and nothing happened so I quickly grabbed my bank card and used that. When I got to my seat a green tick appeared... So now I paid twice
I have a few questions if anyone can help?
- Is NfC quite slow to register when paying normally?
- Where is the sensor on the phone? Maybe I was tapping in the wrong place.?
- Does the android pay app need to be open when paying? I had it open but believe it should work with just phone unlocked.
- I have a thick rugged plastic and rubber case. Would that be an issue?
Thanks for your help any answers appreciated.
Since my first post I managed to get a coffee and into the train and think I have answered most of my questions...
- Slowness I think was just because it was the 1st time I had used Android pay. Subsequent payments are fast.
- NfC must be near the camera, works immediately when I tap there now.
- thick case is no problem.
- Phone works unlocked no need to open the app and displays a handy notification on screen for successful payment.
So I'm sorted and I'm not even in the office yet.
Not sure if buses hate me or the readers on buses are different but I'm finding NfC slow on buses in London. But great everywhere else?
You don't need to unlock the phone, just turn the screen on.
You've already answered your own questions, but yes the NFC chip is just under the camera and for me payment it's practically instant.
Monday and Tuesday I used my android pay at work and then the past two days the NFC chip isn't being picked up. I noticed that it's not as strong as the one in my previous phone but is this chip weaker than other phones apple or android?
Make sure you're using the right part of the phone. The NFC chip is apparently just under the dual camera area.
The logo is the NFC area. Don't slap it against the top edge like an iPhone and you should be ok.
I'd say there's definitely something wrong with the NFC chip, maybe it's just under-powered, it's really hit or miss for me. Tried using Android Pay in 4 different shops, and it only worked once. I used both the area under the rear camera and around the Razer logo, no luck.
Definitely something wrong with my nfc chip too. Android pay works sometimes and not other times. Totally hit or miss
Sent from my Phone using Tapatalk
I think it's a bit hit or miss depending on the payment terminal. As strength seems to vary depending on shop.
Yeah, this phone is absolutely brutal for NFC range.
Tried it at lunch in my local fast food shop and took about 10-15 seconds to get it to work. I really miss the power of the iPhones NFC chip as it was as quick as taking it out your pocket and holding it near the terminal, scan the finger and done.
Now its like taking it out the pocket, unlock the phone then wave it around for 10-15 seconds to get the phones nfc chip detected.
I've tried at multiple vendors, it has worked at all for me. I just hold right under the camera on the scanner and it works every time.
never had an issue with mine scanning.... i do have an issue where it scans multiple times in succession, which causes the transaction be to declined for using multiple cards. Reading NFC tags read multiple times too.
My phone at the location did beep a few times and then send me a Android Pay error request form to fill out on the phone. Its a shop at work so not the worst place for it to fail on me but only happened at this location to me so far.
The chip really is weak or has a serious issue
half the shops I try it at say that i'm trying to use 2 contactless methods at once while the rest don't work at all
All I have to use it with is vending machines around here. I've had it work the times I've used it, but each time it would read incorrectly, forcing me to try again (working the second time).
the nfc chip doesnt seem to be as strong as it has been in my iPhone 6s Plus but its too hit or miss to say if its the phone or the contact payment terminal where the fault is. I have a local Tesco i have no problems with at 3/4 desks and one where it doesnt work at all.
The shop have said some people have issues at this desk but doesnt explain the one terminal at work in our shop where it worked for the 1st two days with some hassle and now doesn't work at all.
Ive been told to unlock the phone hold it to the terminal and wait for the tick before removing the phone but sometimes at the local shop at work in the 2 days it would error 1-3 times before being successfull however i just gave up at the point it didnt work at all on day 3
based on the poor nfc chip which i can only assume is hardware related as i dont see software correcting the issue im going to invest in an android watch with a nfc chip in it and use that.
Currently when i switched over from iPhone 6s Plus and iWacth 1st gen i picked up a Razer Nabu watch to get me through to xmas but feel i need a bit more than the smart features this is currently providing me with. Its not got any support as such as the data from the watch doesn't want to communicate with Google fit and do miss the nfc.
Unsure which watch to get so looking at this currently
