So I’ve manager to get my proxmark3 working and have successfully read an EM 410x chip and then cloned i onto a T5577 card using:
lf em 410x_write [Source Chip ID] 1
however, when it comes to writing onto my new flexEM T5577 chip, it appears to write successfully in the same way but when I verify the implanted chip through:
lf em 410x_read
it shows the previous em tag ID as well as no apparent changes to the device (i.e. it is not showing the cloned information from the first tag).
I must point out that nothing else has been done with this implant other than taking out of the box and implanting it (in future I will obviously test this before surgically implanting )
I’ve popped emails to DT and Kai from ksec and it was advised to open this post in the mean time.
Any assistance would be appreciated!
