I am trying to write on one of those cards, I got from eBay, advertised like that.
Both on Linux (Ubuntu 12.04 LTS) and on Windows 8 (pre-compiled client) it seems
like I can't select this "magic chinese" card. Any idea to point me to the right direction?
This is the version of the proxmark I am using:
proxmark3> hw version
#db# Prox/RFID mark3 RFID instrument
#db# bootrom: svn 839 2013-12-05 07:11:23
#db# os: svn 852 2014-04-01 13:05:51
#db# FPGA image built on 2014/03/21 at 19:45:15
uC: AT91SAM7S256 Rev A
Embedded Processor: ARM7TDMI
Nonvolatile Program Memory Size: 256K bytes
Second Nonvolatile Program Memory Size: None
Internal SRAM Size: 256K bytes
Architecture Identifier: AT91SAM7Sxx Series
Nonvolatile Program Memory Type: Embedded Flash Memory
The HF antenna reacting to the card:
proxmark3> hw tune
#db# Measuring antenna characteristics, please wait...
#db# Measuring complete, sending report back to host
# LF antenna: 0.00 V @ 125.00 kHz
# LF antenna: 0.00 V @ 134.00 kHz
# LF optimal: 0.00 V @ 12000.00 kHz
# HF antenna: 11.79 V @ 13.56 MHz
# Your LF antenna is unusable.

Trying to get a block from the card (Linux terminal):
proxmark3> hf mf cgetblk 0
--block number:00
#db# wupC1 error
Can't read block. error=2
Trying to set a block on the card (Linux terminal):
proxmark3> hf mf csetblk 0 01020304050607080910111213141516
--block number:00 data:01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16
#db# Can't select card

Similar results from the Proxmark Tool on Windows:
proxmark3> hf mf csetuid 01020304
--wipe card:00 uid:01 02 03 04
#db# Can't select card
Can't set UID. error=2
proxmark3> hf mf csetuid 01020304 -w
--wipe card:00 uid:01 02 03 04
#db# Can't select card

proxmark3> hf mf cgetblk 0
--block number:00
#db# wupC1 error
Can't read block. error=2
proxmark3> hf mf cgetblk 1
--block number:01
#db# wupC1 error
Can't read block. error=2
I also tried the function "Restore Corrupted Sector0Block0" on the tool, this is what I get:
proxmark3> hf 14a raw -p -a -b 7 40
received 0 octets
proxmark3> hf 14a raw -p -a 43

Any hint would be greatly appreciated!

Trying out the Proxmark Tool a little more on Windows, it gets slightly different error messages, still I can't figure out what's wrong

Try to put some distance (1cm) between antenna and tag.
