i bought this PM3 from China(Taobao)
and it comes with customised firmware(works fine with hf cmd)
now i'm trying to update the firmware to latest version
but once i flashed the firmware,
the PM3 cannot read m1 card any more, still see HF voltage drop
i have tried 2.0 2.1 2.2 2.4, all have the same issue
anyone has any idea that what may be causing the issue?
cheers

Your HF voltage is kind of low, try different antenna or distance between antenna and tag.
If still not working, try the solution in this thread: http://www.proxmark.org/forum/viewtopic.php?id=2635
Use an older fpga_hf.bit image from 2015-01 ish.. Download it from GitHub or in the thread above.
Then you compile /flash your pm3 and try again.
