If nothing else has worked ,
and you dont have a Proxmark, and nobody else here has any ideas,
(Since Amal already has your details)
Rather than a DM to Amal, if you use the support tool on the DT website, by hitting the floaty orange help button
Yes. I have an android. It just says can’t read chip type and gives me the invalid card error. My computer can still read it when I go to unlock my pc with it but all its doing is typing in the uid.
Ok you will need to use the proxmark3 when it arrives to investigate what’s going on with the tag memory that might be causing the Android NFC stack to bail on reading or writing it.
I was finally able to get a proxmark3. I ended up buying it from your website actually but I cant seem to read the tag. Could you walk me through reading this type of tag in case I’m doing something wrong. It says
[!] iso14443a card select failed
[!] No Ultraligth / NTAG based tag found
Can you try writing an NDEF message with your phone to the NTAG216 card that you would have received with your Proxmark3.
And then try reading it?
What result do you get?
Have you confirmed your proxmark is set up correctly?
What commands have you tried on your proxmark so far?
hf search
Once you reply with the answers and results, if you have no luck, we can try a few more things…
if you are unaware, an easy way to reply to my questions, would be to highlight the text and select “quote.”
So the app NXP is the only app that will read it. It will scan it and show me the data. The same data id get if I ran hf mfu info. The proxmark seems to be picking it up now just fine. The rest of the apps I try to use on android all bring up an android prompt saying invalid card. Im unsure how to use proxmark as its my first time getting this dirty with the code. I don’t know what the next step would be. Thank you in advanced for the help.
On the proxmark I’ve tried to restore but I’m unsure how to input the files and key. I feel like if I could restore it with a blank file that might fix the issue but I’m unsure as to how to get a blank file and how to write it via the proxmark.
