Ok sorry for late reply! Been frantic.
So, I managed to “brick” a text xEM by programming a HID ID, and then programming block 0 config to modulate for EM ID LOL! Turns out then the pm3 cant even t55xx detect in that state anymore, (thinking of a way to fix this in the pm3 client and open to suggestions) I suspect this is where you are at…
So what I did to fix it was the following after starting up the pm3 client on the latest git pull form the RRG repository:
1. lf t55xx wipe
2. lf t55xx config d ASK b 32
3. lf t55xx detect
4. lf hid clone 2004840534
5. lf t55xx detect
6. lf search
You should get HID ID with a card value of 666 and facility code of 66.
Give this a try and let me know how you go!
