help: Resetting T5577 card to default after i wrote it as a EM410x tag

I had a T5577 card which i tested and was able to code it into a HID, indala or viking using the PM3.
then i used a china multi-freq device (with the color lcd) and write it with 125khz mode while testing the device.

This is what the card shows now:

Reading 30000 bytes from device memory
Data fetched          
Samples @ 8 bits/smpl, decimation 1:1           
NOTE: some demods output possible binary
  if it finds something that looks like a tag          
False Positives ARE possible
Checking for known tags:
EM410x pattern found:

Valid EM410x ID Found!         

Now i can't use the tag as a HID or Indala or viking tag anymore as it seems to be "locked" to the em410x
how can i reset the card so that it can be used as a t5577 again?

you can try
lf t55 wr 00148040 00000000

but will break your card if locked by password as iceman said
