Writing 0 sector
Hi,
I bought some nfc tags from ebay and they are 0 block writable. I would like to change the whole 0 block of sector 0 (I want to change the whole 16 bytes). What I have achieved so far is to change the uid (first 4 bytes) however the following 12 bytes get wiped.
Info:
proxmark3> hf 14a read
UID : aa ee ff cc
ATQA : 00 00
SAK : 08 [2]
TYPE : NXP MIFARE CLASSIC 1k | Plus 2k SL1
proprietary non iso14443-4 card found, RATS not supported
#db# halt error. response len: 1
Answers to chinese magic backdoor commands: NOHow I changed the uid:
proxmark3> hf mf csetuid aaeeffcc
uid:aa ee ff cc
#db# halt error. response len: 1
No chinese magic backdoor command detected
#db# halt error. response len: 1
#db# Halt error
Couldn't get old data. Will write over the last bytes of Block 0.
new block 0: aa ee ff cc 00 00 00 00 00 00 00 00 00 00 00 00
#db# halt error. response len: 1
#db# Halt error
Can't set block 0. Error: 2
Can't set UID. Error=2So after this command I do change the uid to aaeeffcc but the manufacturer information right after it gets wiped (00's).
I would like to change the whole block 0 of sector 0. Apparently the proxmark3 is able to wipe it so in theory it should be writeable as well. How can I do that? hf mf wrbl 0 a ffffffffffff 000102030405060708090a0b0c0d0e0f doesn't work.
Thanks!

Re: Writing 0 sector
You're running chinese commands to a card that isn't detected as chinese (Answers to chinese magic backdoor commands: NO).
Which is why you get "No chinese magic backdoor command detected".
try running "script run formatMifare -x" on the iceman fork then try the "hf mf wrbl" command.

Re: Writing 0 sector
Yesterday I had a old firmware on my new proxmark3 easy. Today I flashed to the newest. After doing what you suggested I was still not able to revive the tag.

It didn't work because you're not using the iceman fork like I told you to. The script on the original does not have the "-x" option as it's an old script.
You can either copy and replace this file: https://github.com/iceman1001/proxmark3 … Mifare.lua
OR
Use/Flash the iceman fork: https://github.com/iceman1001/proxmark3
BUT
Looks like after you flashed to the new firmware it is indeed a Chinese card (Answers to chinese magic backdoor commands (GEN 1a): YES)..
SO
Try running the "hf mf cwipe 1"command to restore it.

Re: Writing 0 sector
I understand. Thanks.
Just FYI, however the iceman fork should solve it:
proxmark3> hf mf cwipe 1
#db# halt error. response len: 1
Chinese magic backdoor commands (GEN 1a) detected
--blocks count:64 wipe:y fill:n
#db# wipeC error
OK
proxmark3> hf 14a read

Re: Writing 0 sector
...even I am confused now...
1) the script doesnt execute the generated commands, just cut 'nd paste it and you will execute them.. Don't need to flash/compile icemanfork
2) you need latest offical pm3 or iceman fork to program your gen1a tag. It seems to be one of those tags that answers the halt command. The command should been executed anyway (if you are on the latest source)
3) set a new UID with hf mf csetuid since you seem to have messed it up. I'm guessing a faulty BCC value. This should enable your tag again.
