Experimenting Nexus 4 with Mifare Classic 1K tags

I tested this on a brand new Mifare Classic 1K tag today with my N4.

I opened NFC Task Launcher and added a simple action to Open URL/URI to xda-developers.com. Here is what the app says when I try to write the task to the Mifare Classic tag.

"It may still work, but you may see the chooser when tapping it"

Afterwards when I tapped the N4 again to the NFC tag, the browser opened xda-developers.com with no problem. No chooser came up...

Subsequently I tested that the Mifare tag is able to read/write to my N4 for toggling WiFi, bluetooth, play media etc. I don't have the time to test every action in NFC Task Launcher but it looks like the majority of the actions probably still work. It's just that the app will give a warning/error when you're trying to write to the tag.

I also tried reading the Mifare Classic tag with TagInfo...

Neither screenshot is too encouraging for Mifare Classic 1k compatibility with our Nexus 4.

So in summary, if you have the option to choose between using NTAG203 and Mifare Classic 1k for the Nexus 4, choose NTAG203. If you don't have an option, then Mifare Classic 1k may still meet your requirements depending on what you do, so by all means give it a shot.

What I can definitively say is that Mifare Classic 1k tags are not 100% totally incompatible with Nexus 4.

Hope this helps.

Since I have both the note 2 and the n4 now, I have a better understanding of this technology.

Since this is the n4 forum, I'll limit it to the n4.

There are 2 different definitions of work. The n4 can read the milfare tags, and use them to different tasks based on what you program the phone to do when it reads the tags.

If you program the tag to turn on wifi, then when you scan it, you will turn on wifi on your phone, but not on any other.

Now with the ntag, you can write a command to turn on wifi, and it will work on your phone, and any other nfc enabled phone.
[Nexus 4 Accessories] Robogar:
That's strange, I'm doing a similar test and have different results, can you confirm?

I have infront of me a Nexus 4, Sony Xperia V and blank MIFARE 1k tag.

1) Write to NFC Tag launch XDA Developers URL with Nexus 4. Nexus 4 is able to launch XDA Developers URL. Xperia V also able to launch XDA Developers URL.

wipe the tag with Xperia V

2) Write to NFC Tag launch XDA Developers URL with Xperia V. Nexus 4 is able to launch XDA Developers URL. Xperia V also able to launch XDA Developers URL.

wipe the tag with Xperia V

3) Write to NFC Tag Toggle WiFi with Nexus 4. Nexus 4 is able to Toggle WiFi. Xperia V is NOT able to toggle WiFi.

So I guess it depends on the type of task you want it to do.

Perhaps launching a URL is more text based - the tag just contains something like launch://www.xda-developers so it works? Any developers can shed any light to this?
[Nexus 4 Accessories] krohnjw:
The Nexus 4 *cannot* READ or WRITE data to Mifare Classic 1K tags, period. This shouldn't even be a discussion at this point. The controller does not support it. This is also the controller used in the S4.

Here's what's happening with NFC Task Launcher when you write with the Nexus 4:

Scenario 1:

Inabilitlity to write detected, actions saved via local mapping

Payload pushed to cloud service

Xperia reads tag, NFC Task Launcher picks it up

NFC Task Launcher finds no actions so it queries the cloud service for a saved payload for this ID

Xperia caches instruction set and runs it

So, it appears as though it was "written" when in reality nothing was written. When a second device scans this tag (assuming it is sent to NFCTL) it will see no actions, query the cloud for a saved payload and use that if it exists.

If you write a different data set (say a bit of text only) onto this 1k tag with the Xperia it won't matter to the N4 as it can't read the data. It will continue to do an id based lookup for this and execute the payload associated with that id.

Here's some info on the NFC tags that are out there. It's also a good source for the harder to find tags like topaz, which holds more data than the more common NTAG203. NFC chip types
[Nexus 4 Accessories] krohnjw:
The Galaxy Tab 2 doesn't have NFC as far as I can tell. Are you actually able to select NFC task? There's a check to verify that the device reports it has NFC prior to allowing you to select this (it's not displayed on non nfc devices). This is the only way you'll ever see the write screen.

[Galaxy S III Q&A, Help & Troubleshooting] justin911:
Hi

I've got the samsung s3 4g version but I believe the normal S3 has the same issue. When I go into the call history it shows calls from everyone over the last 30 days or something which is good, but when you click on an individual number it only shows you the history for that specific day.

I used to have a S1 and on that if you clicked a number it would show you the history (calls/sms) for the entire history duration, so you could see you spoke to that person a 3 days and a week ago for e.g.

Is there anyway to get the S3 to do that... ? it seems silly if they took that feature out of the S3 ?

I was looking on google and someone said to get "mr number" I tried that, but that seemed to make it worse and not show me any history (just a list of all the ppl who i spoke to)

If anyone knows howto get the history/logging to do what I need that would be great.

thanks
[Galaxy S III Q&A, Help & Troubleshooting] justin911:

[Galaxy S III Q&A, Help & Troubleshooting] TheDestroyer:
I've got the same problem.

Before I9300 I had Touch HD where I used an Address Book app. There I could click on any number in call history and get the entire history of calls and sms from that contact or number.

But on SGS3 I can only get the history/logs of calls for the contacts that I've written to my contacts: logs(call hystory) - long tap on contact - open contact- menu soft button on the bottom left - journal.

But I've got a lot of calls that are not in my contacts and I don't want to save them and I need to see if that number allready called me.

How can I find it out?

Thanks in advance.

I saw this behavior too after rooting and enabling Google Play. I would see any of the following occur:

1) An 'x' on the wifi icon even though I had a wifi connection (drop down wireless menu shows connected, web browser works). I would see the 'x' shortly after restaring the KFHD.

2) No wifi icon and no connection. Reconnecting to wifi taking forever or fail authentication

I think I fixed up #2 by setting up the wireless connection profile again. #1 seems to happen whenever I wake the KFHD...after a min or so the 'x' usually goes away, but not always.

A non-issue for my KFHD so far.

[Eee Pad Transformer Themes and Apps] grgmre:
Can anyone recommend an app that will search my tablet for unused files and folders and delete them? I'm currently using SDMaid but it's not very effective.

After noticing I was running low on room internally I used Storage Analyzer to find what the heck was taking up so much room. As it turns out a lot of installing/uninstalling games and a bunch of ROM flashing and upgrading has left a lot of kruft on my system. Manually going through and deleting stuff yielded an extra 3 gig of internal space without having to remove a single app.

I'm pretty sure there's a lot more crap buried on this tablet. Has anyone got a recommendation on something a little more powerful than a cache cleaner?

So I am rooted w Nookmanager. I followed the instructions to the letter. I couldn’t be happier with the rooted Nook.

Since Im still a n00b at this..i have a few questions:

1.	Which is the back up file of the original Nook, so that I can transfer it to my laptop and save it for any emergencies.

2.	Also , my sd card (16gb) is only showing a fraction of the space when I insert into the sd card reader of my laptop. How can I get its full 16gb space back. Do I need to reformat it? If so, how and what software can I use?

3.	I have some ebooks already saved in the My Files section on the internal hard drive of Nook. These books don’t show up on mantano reader (or other 3rd party reader apps I have installed).

a.	I want to save my ebooks in a folder from where I can access them through Nook native reader as well as any third party readers I have installed.

Thanks for your help…. And long live XDA :)
[Nook Touch General] jun127:
Step 1. Insert microSD and connect your nook via USB.

Step 2. In windows explorer there will be a drive labeled backup. That's the partition Nookmanager created on the SD card.

Step 3. Open it up and copy the 2 files that are in there.

Getting your space back (after you copied off your backup):

Step 1. Start menu, search "partition", you should find windows partition manager in the control panel.

Step 2. Find the SD card which is now divided in 2 partitions, delete the partitions

Step 3. Right mouse click and create new simple partition, fat32.

[Nook Touch General] sLiKK:
THanks.

I used Minitool Partition to format, delete the partition and then create a new partition . But in the process, I now have only 14.8GB. I lose 1.2GB. My original card was 16GB. is there anything I could do to get the lost space?
[Nook Touch General] jun127:
That's the full size. A "16gb" SD card is actually about 14.83gb because SD cards are sold by the bit. About 15.9 billion bits in a 16 "gb" card, divide that by 1024 three times and you get 14.83 something gb, and that's how windows see's it. Don't worry, you didn't lose anything. ;)
[Nook Touch General] sLiKK:
Oh..okay...thanks alot. :)
[Nook Touch General] tooplanx:
Hiya, I know a bit of time has passed, but I'm having problems finding my stock back-up image I made.

I've followed the instructions as above, but explorer doesn't show the backup partition at all. I just have 'Nookmanager' and 'Nook' (the internal memory). I'm connected to the sd card through the nook simple touch (i.e. not through an sd card reader).

Any ideas how I can access the hidden back-up partition?

Many thanks in advance.
[Nook Touch General] cowbutt:
I don't think the Nook will present second and subsequent partitions on the SD card for USB mounting. You'll need a memory card reader; a cheap one from eBay will do the job.

The files are backup.full.gz and backup.full.md5 in the NookBackup filesystem.
[Nook Touch General] Joydeck:
I have a similar problem in copying the two Nook Backup files to my PC. Using a standalone SD card reader, I can see the 1.78 GB NookBackup partition in my MiniTool Partition Manager and in XP's Disk Management, but I cannot assign a drive label. The 64 MB NookManager partition is assigned a drive label, but NookBackup partition shows no drive assigned.

Since I cannot see the two backup files in Windows Explorer, how can I copy them to the PC?
[Nook Touch General] cowbutt:
http://superuser.com/questions/61487/usb-sticks-and-multiple-partitions looks useful.
[Nook Touch General] tooplanx:
I've tried both with a card reader and through the plugged in Nook. No joy either way. I looked at the card in Win7's Partition Manager and although it shows the extra space, it doesn't show it as being active or labelled or anything.

When I did the backup it took ages (nearly 30mins) and I was beginning to think it was stuck or something, but then it said it was completed.

I'm wondering whether it actually failed to create a backup. No sign of a backup or backup partition any where.

I think I might just format the card and hope I don't get any problems. Everything seems to be working ok.

Is it possible just to download someone else's backup or get the firmware off B&N again if I need it?
[Nook Touch General] cowbutt:
No, your /rom partition is unique to your device.
[Nook Touch General] straygecko:
The memory card reader won't help as windows won't allow you to mount anything other than the first partition on removeable media. What you need to do is boot your Nook from the NookManager SD card and then plug it into your PC. You will then get two new disks in Windows that each show a single partition. The first disk will be the 64MB NookManager partition and the second disk will be the NookManager backup partition that takes up the rest of your SD card. If for some reason Windows doesn't automatically assign a drive letter go into the Windows partition manager and assign one. The key is you must be booted into NookManager. It won't work if you are booted up normally to read books.
[Nook Touch General] Joydeck:
Works well.

Having copied the original Nook partition to Windows, could I also backup the rooted partition from the NookManager backup menu? I would also copy the new folders on the SD Card. Or is there another way?
[Nook Touch General] cowbutt:
Yes. Note that NookManager's 'Backup' function will overwrite any pre-existing backup on the NookManager partition, so transfer your backup of your stock firmware first before you make a backup of your rooted firmware.
[Nook Touch General] tooplanx:
Ah... that sounds like it might work! Unfortunately, after spending several hours messing around with the sd card and the nook trying to make the other partition readable using partition manager and EasUS, I gave up and just formatted the SD card so that it was usable again. I did a data recovery sweep on the other hidden partition before-hand and managed to retrieve a .gz file of approx 49MB. I presume that is the back-up, but I couldn't retrieve the other file.

Oh well, fingers crossed I don't have problems :fingers-crossed:. At least the Nook was very cheap (£29) so it's not the end of the world if it things go bad.

Thanks for your help. :good:
[Nook Touch General] straygecko:
49MB sounds a couple of hundred meg shy of a backup. You can try unzipping it with something like 7zip to see if its any good and worth keeping around but I doubt it. The other file you didn't recover is just an md5 of the backup and isn't necessary other than as a confirmation of a good backup.

You should take another backup of your Nook as it is now and keep it. That way you'll have a backup of your ROM partition so if things ever go too far south you'll be able to use someone elses full backup and then replace the ROM partition with your devices information.
[Nook Touch General] cowbutt:
What straygecko said. 49MB sounds too small, and even a non-pristine backup is worth having.
