PM3 Antenna Problem

Hi everyone. Just purchased the Proxmark3 Easy with Iceman firmware from this website. Got it in the mail today and followed all the instructions to get it set up, but I’m met with this error:

[usb] pm3 --> hw tune

[=] -------- Reminder ----------------------------
[=] `hw tune` doesn't actively tune your antennas.
[=] It's only informative.
[=] Measuring antenna characteristics...
[-]  9

[=] -------- LF Antenna ----------
[!] LF antenna............ unusable

[=] -------- HF Antenna ----------
[+]
[+] Approx. Q factor measurement
[!] HF antenna ( unusable )

[-] All values are zero. Not showing LF tuning graph


[=] Q factor must be measured without tag on the antenna

I’ve checked out some previous forum posts and done some basic troubleshooting. I’ve restarted my PC, deleted and reinstalled all firmware, and inspected the physical device, but no luck so far.

I don’t have a multlimeter, but the screws all appear to be snug.

Any help is appreciated!

take a picture of the proxmark top-down for me

Can you also confirm your computer OS, firmware version and client version? This should be displayed when you first run the client. Screenshots work fine :slight_smile:

Here’s all the info. Let me know if I missed anything

Hmm… I don’t think so. What happens if you just do hf tune and lf tune ?

remove the lf antenna and clean all the contact pads

Shows 16 mV / 0 V / 0 Vmax and 60 mV / 0 V / 0 Vmax, doesn’t seem to detect anything near it.

Just as soon as I can find a screwdriver that fits this thing lol

Both lf and hf antenna is reporting unusable.

This seems incorrect. I would reflash the bootloader and rom.

good spot i only noticed the lf unusable

@abcdef1234 change the cable you’re using for a reliable one too.

I re-ran ./pm3-flash-bootrom and ./pm3-flash-fullimage, still the same error. I’ll look for a new cable I guess

I would rebuild and flash. To me it sounds like generic wasn’t built

Ran the make command + the flash commands, still nothing. I wish there were more debug info to show

it wouldn’t flash if it wasn’t built it just says no executable in workdir when that happens.

@abcdef1234 if you’ve tried with another good cable then id say your proxmark is busted. return refund and replace wherever you got it from.
