rdv4 writing EM4X50

Hello does anyone already had this problem

i'm attempting to write to em4X50 tag yesterday was working perfectly and today i have the message writing failed

I dump the tag only 0 digit in the dump prompt but when i dump it with my icopy-x everything is ok and the writing with the rdv4 worked even he returned a failed writing message.

I'm runing on windows 11 but tried on kali and it's same issue

Thanks everyone for your answer

Re: rdv4 writing EM4X50

hello, i am writing about this type of badge without particular worries, it is important that there is no passwd in your badge.lf em 4x50 info & you will be able to see it, otherwise i am only writing in --blk 5 & 9 . What's also interesting with this badge you take the dump of another badge that works elsewhere & do a restore works very well too.


Ah yes also check that your rdv4 antenna is on Q 14

Re: rdv4 writing EM4X50

Hi, although everything is back to normal, I'm working with an rdv4.0 & the latest Iceman update, which I thank by the way. I don't know icopy-x, my Os & linux & also on Windows 10 but I prefer linux. Install the latest version on your rdv4 if this has not done.
Good day.
