t5577 card not working

Hello,

I just received my proxmark RDV4 from Hackerwarehouse with 2 cards one t5577 card and the other GEN1A card from ProxGrind.
I cloned my em410 tag to the card t5577 which it worked perfectly, but when I try the card t5577 from proxgrind on the door reader of the building it doesn't work.  The only thing that is different is the buffer samples.
Any help please? how can i copy also the buffer sample to be the same as the original fob.

Thank you

Steps:

1. EM410 fob:

3. I configured the device for the t55xx card:

#db#   [d] write_1.............47*8 (376)          
#db#   [e] readgap.............15*8 (120) 

P.S: I tried to wipe out the card and write it again but it didn't work after configuring the device.

Re: t5577 card not working

Hey Iceman when I do lf t55 detect it gives me:

 [!] Could not detect modulation automatically. Try setting it manually with 'lf t55xx config'

.

But right now it's not working anymore:

Do you think that the card is damaged and need to be replaced or do I need to use the official repo from GitHub instead of the RRG repo?

Thank you in advance for your help.

Re: t5577 card not working

There is a lot of wrongs here.

First, you seem to be confused about t55xx config and t55xx deviceconfig.
Second,  when reading a t55xx tag, where you set FSK and a wrong bitrate in order to read a em410x will be problematic.

So before I would even think about saying "damaged card" or swapping repo I would consider trying to understand what I am trying do to and maybe even read a datasheet or two...

Re: t5577 card not working

I still couldn't find any explanation about the buffer samples. Can you please guide me through or enlighten me with your knowledge.

Thank you
