Two unresponsive T5577 cards

This is my first post so let me get it out as clean as I can, any help would be appreciated

Recently bought my first Proxmark 3 Easy via amazon,

Things were going good for the first 24 hours. I copied a HID work badge to the T5577 HID card that came with the kit and It worked fine the next day when I used it, aswell as when I returned home and read it again.

Until I tried to read it two days later and It wouldn’t respond to ‘lf search’ ‘lf t55 detect’ or ‘lf t55 info’
The only time the Proxmark recognized the card was sometimes it would scan as an Indala tag with random raw data stream everytime. I later abandoned that card for the remaining T5577 generic card.
Attempted to write a raw line to it and then made that card unresponsive as well.

Only weird thing is that the second card I can still read, even “wipe” it, but no matter what all blocks are now FFFFFFFF 0-7 on both pages. Manually writing ‘lf t55 write -b 0 -d 0088040’ to the card does nothing.

As I said this is my first time getting into RFID tools and I’m not sure if this is the right place to ask for support for something like this but I gotta start somewhere. Any help would be great, if you need further logs or information just ask I can try to get them. Thanks in advance

Random noise is often identified as indala.
That’s about all I know.

Sure there are people that can help you I guess. There’s also the Iceman Discord which is probably also a great resource (you gotta search the link)

out of curiosity where on the proxmark are you placing the card

For card placement I’ve been using ‘lf tune’ to achieve the best placement via voltage drop then leaving the card there throughout the process

EDIT: So far I’ve resolved the issue, a mix of bad writes and unknown data basically. I encourage anyone who is having troubles to visit the Iceman discord, I was able to get the help I needed there :slight_smile:
