TagWriter writes and reads YT link, Taginfo says xsiid is blank?

Hello all!, so I have been letting my xsiid implant heal for almost a week now, and its getting easier to scan and see, and so I started really experimenting with it, loading it up with youtube links and even some encrypted text and so on, but then I was using Tagwriter app, by NXP, and went to erase it, as I had moved to that app from nfc tools cause it was kinda garbage, and it said it could not erase as parts of it were write protected, so, I was very confused, I had not touched any of the read/write protection stuff, didnt want to get into that so soon, so I know for a face I did not lock it myself, and also, when I overwrite it with something, I can scan it and it shows up/ works in tagwriter, but in taginfo app, its says its blank.
I am very confused here friends, anyone know what to do?

Ok, after doing some thinking, and retrying taginfo I got this in the memory content output area when scanned:

Sorry to leave you hanging, Check out this :arrow_down:

Oh and :arrow_down: @Aoxhwjfoavdlhsvfpzha question

Does the link launch on your phone when you scan it outside of an app?

It seems odd to me that there’s data all the way up to E2 if all you wrote to it is a link

I didn’t go through the whole thing, but nothing seems glaringly wrong to me

Definitely try out the above fix @Pilgrimsmaster posted though, I didn’t need to use it on my XSIID, so I can’t speak for it, but others have had great luck with it

Ok I did that stuff, used the recommended app and it worked, I think, and then went back and overwrote the yt link with a plain text file saying yeet blah blah so on, and then it worked, wrote, and then reads fine, but I cant erase it, neither option in tagwriter’s erase section works, it gives me two different errors, for the erase to factory default one, it just says “This tag can’t be erased, (parts of) Tag protected”
The other erase function, the NDEF one, says "write protect failed (unknown error)

it did when I had it on there yes, so the data I write to it is intact, but it just fails to erase and there is all this extra garbled shit in the ndef readout that I have no clue why its there

I know you said you didn’t like NFCTools, but have you tried the erase tag option there?

Yea, it works there, and I can write to it in NFC tools as well, but if I write something to it with tagwriter, it does not appear when scanned in nfc tools, it shows the device as empty, no record, no used space, nothing, but it is definitely there

I’m not certain what would cause that disconnect unfortunately, I just tried writing to a tag with tagwriter and then checking with NFCTools and it shows a record for me, the best I can recommend at the moment is to retry after the ndef fix pilgrimsmaster posted

Hopefully it works, or I’m sure someone else will be here with an idea

Edit: Tagwriter erase also works for me

Good luck!

ok will do, thank you

I have retried the above possible solution 4 times now, and it is still producing that long garbled stuff in the ndef record and not letting me actually erase it in tagwriter , and in nfc tools, if I erase it works, but afterwards if I got back to taginfo it still has the dangerousthings link in the ndef from the above reset commands.
I am really stumped and bummed. I appreciate all of your help here, and I suppose i will sleep on it for tonight and come back to see if anyone might have been able to find a solution to help me out.

Just to clarify, it’s Tagwriter creating the jumble?
You may try writing to the tag once with NFCTools and then seeing if that formats the ndef section properly

Beyond that, what I would probably personally try is zeroing out a chunk of the user data manually with nfc shell before retrying the fix and writing an ndef record

I honestly don’t know what is making that jumble, all I know is it shows up in the FULL section of taginfo, but otherwise other apps all think its empty.
I will try writing with nfc tools, will post results, then I have to turn in for the night.

Ok so I wrote a YT link to it in NFC tools, after eraseing it with same app, Then, tested to make sure the record link worked, which it did, and then went into taginfo and did a FULL scan, now the jumbled data is still present in the full ndef read out, but it appears that when I write something new to it, using NFC tools, if overwrites just the space that the new record uses, which means that YT link is then followed by whatever cut off part of the assumedly trashed remaining ndef record data.
Should I attempt to overwrite it all? I don’t know with what but if it would mean I could get rid of all that junk written in there would it be worth it to try?

If you’d like, I can DM you a whole bunch of lines for NFC Shell to 0 out the entire NDEF record except for the fix section, that will definitely get rid of the jumble

Or, if you have a different method for getting rid of the jumble, that should work too.
It also probably wouldn’t harm anything to leave it there, but I would want it removed personally for no real reason

Oh, yes please do send me that shell info!
Ill give it a shot as soon as I can and get back to ya. Thank you!

I was going to DM it to avoid sending a few hundred lines of code into the forum, but just in case anyone else with an XSIID wants a completely clean NDEF section:

Copy and paste the text into NFCShell, and then overwrite the Dangerous Things link with your record of choice
Tested on my implant, and it takes a few seconds, so hold your phone there until NFCShell finishes

This should work on the 1k versions of the XSIID as well, the addresses look the same on the datasheet, but I only have the 2k version to actually test on

Oh Christ please don’t use NFC Shell if you don’t know what you’re doing. There wasn’t much risk of bricking the implant with NFC Tools or TagWriter because of the way the chip is configured from DT, but if you start sending raw commands without knowing what every single line is doing you seriously can brick the thing.

What happened with all the garbled nonsense at the end is that you were writing new links to your tag, and it was adding them as new “records” at the end of the NFC “message”. Unless you factory reset or manually overwrite, the empty space will remain messy.

TagWriter has been throwing up that error because a true “factory reset” would change the configuration protection settings that DT loaded, and it can’t do it because there’s a non-default password set. I’ll take a look and see what I can do

Ok so this is what you were seeing. It’s because TagWriter sucks

Here’s my NExT (similar memory structure) with a multi record NDEF message written to it.

You can use the “Format Memory” option in NFC Tools to clear the empty space without password authentication.

And here’s the NExT after being cleared.

Now that you know about NFC Shell please do be careful and ask before you write.
