Yes I have decompressed the .zip file and I tried to flash the .nfi file on the original box but this one refuses to flash my box it puts me the following message when I launch the flashing INVALID IMAGE (OR OLD VERSION) and this is the cause I do not know how to move to the next step to replace with the new sim japhar and continue flashing a new japhar image. I have a problem with the file secondstage-dm800se-84-allsim.nfi I think my version secondstage is superior than the 84 and it blocks the flash, I need a version secondstage-dm800se greater than 84 -allsim.nfi.I tested the flash secondstageDM800seV2-SSl88J and this one to flasher my box but to the change of sim the message BIOS NO CA FOUND is displayed. Thank you for your help.
