Just installed the xEM implant into my right hand. Attempting to clone a HID card, and it appears that the implant is bricked. I have a proxmark3 rdev4, and have had no trouble cloning Mifare and HID cards up to this point. Any help would be appreciated as I donāt want to have to cut this out of my hand and install another one.
Thanks,

What happened? Is the Proxmark not recognizing it, or is a reader not recognizing it?
Proxmark canāt identify a modulation scheme, a lf search returns a nice sine wave on the graph, but no data
Did you manage to get it working again? My xEM (implanted) is showing a waveform on pm3 with the new proxLF antenna but the modulation cannot be recognised.
Fixed it with a lf t55xx write b 0 d 00088040 p AA55BBBB t 
Then I was able to write HID config. Finished up with the following two, which now let me get the t55 infoā¦
lf t55xx write b 1 d E0150A48 1
lf t55xx write b 2 d 2D782308 1
Lol, completely missed this comment! I deleted my last response as it must have been wrong in some way. I mustāve used that command in addition to the million steps I tookā¦ glad you found the fast way!
Iām curious where I can find out more about the flags that are used in this command. is āp AA55BBBBā a password being set?
The reason Iām asking is I have an xEM implant and I tried to use the ELECHOUSE Proxmark 3 RDV2 with the less-than-optimal LF coil that came with it. Iām waiting for a proper coil in the mail that is tuned for these glass chips, but in the meantime I wanted to do more research into figuring out how to un-brick my glass chip and bring it back to the factory defaults it shipped with. I made the mistake of issuing a wipe command and then I applied the block 1 and block 2 command you posted above. Itās still locks up my proxmark whenever I try a ālf searchā command or any basic command to read what is written on the chip.
I guess Iām just asking for some help or some links to educate myself better. Iāve tried the āQuirks of Cloningā forum post, but Iām still getting the same issue.

Have a read through this too. The p value was password set by white cheap Chinese cloner I now believe, though I donāt recall performing an intentional write with the cloner. You shouldnt need to use that switch.
Have a read of the data sheet too for the em chip, that will hopefully fill any gaps left after youāve read the thread I pasted above. Let us know how you get on. I tried just about everything to get mine active again over several evenings, dont give up 
Turns out I hadnāt bricked it. I used the ālf t55xx readā command after doing āhw tuneā and I didnāt realize I could get an analogue output on the oscilloscope while I moved the antennae around until I got the cleanest read possible with the worst possible antennae for the xEM. Once I had about an 85% success rate, I sent the clone command and it took.
I just wanted to thank you for telling me to keep at it. I was too eager and didnāt do my research. In the end, it forced me to read up on several websites until I had a better understanding of everything. Including your link. Iām kinda glad I got myself in this situation.
