I’m fairly new to the Proxmark3 game but I’m a fast learner. I ordered these T5577 chips (https://www.aliexpress.com/item/32817606024.html) and I’m having trouble detecting any of them. They’re reading as EM 410x chips but my Proxmark3 Easy can’t detect them as T55xx. I suspect they are password protected.
I’ve read every article imaginable and tried all the passwords I could find online (as well as running lf t55xx chk with the proxmark dictionary of passwords) with no luck. Does anyone have any idea on how I could unlock them? I’ve tried wiping them in test mode, re-writing them as EM chips but nothing works.
The seller told me I had to use one of these devices (which was not clear on the ad):
Thank you both - no luck on any of the lf em 4x05 commands unfortunately (I had to change 4305 to 4x05 for my Proxmark version).
lf em 4x05 info/dump/sniff/read -a #, etc. have no result.
lf em 4x05 chk runs through the password dictionary with no result.
I ordered them hoping they’d be T5577 chips but they don’t appear to be working EM 4305 chips either (though I’m not really familiar with those) - unless they’re password protected.
lf em 410x reader works and returns the following, though I can’t write it as a 410x chip:
[usb] pm3 --> lf em 410x reader
[+] EM 410x ID 3D00D51E2C
I think you’re right, now that I’ve tried pretty much everything I’m pretty confident they just sent me EM4100 chips instead of the EM4305/T5577 I ordered. Very annoying for my first proxmark experience lol but a good learning opportunity! Thanks all!
