    problems when regenerating hp chips aka uprint plus

    Hi all

    I have problems when it comes to regenerating HP chips aka uprint plus.

    When I write the data back to the chip, when I re-enter the cartridge, it gives me a chip error and tells me that the chip is wrong. The funny thing is that he lets me read it. I do not know if it is blocked or not.

    I have several chips with that problem. They are chips of the year 2012.

    I have 2 chips of 2009 I can read them but not write.

    Is there any way to regenerate those defective chips, dumping an image or something ????

    Thanks and best regards

    You should change serial number or delete file with serials from HDD.

    When we generate the chips, we change the serial number of the chips.

    What happens to us I think is a bug reading the chip.

    The question is can one dump a chip with the wrong image of a correct chip and from there regenerate the chip.

    It can be regenerated without being in the machine the chip

    Here a dump of what I see


    er 0 0 0 128

    000000: b3 8d ad 05 d0 14 10 69 ....... i

    It seems that there is a limit of regeneration in the chips or that seems to me.
