Default Invalid Model ID?? after flashing

hy,
i have flashed my unlocked athena x7500 with rom 6.1 by irius. the update breaks at 82%.
now i have only pixels on screen, and nothing happens.
in the bm stands the following: ' R\
IPL-v1.00
' R\
SPL-v1.25 Olipro

if i try to flash, the updater shows after 1% the error: invalid model id
i have tryed to flash with sd-card (tested with os.nb, ruu_signed.nbh, spl.nb and os.nb0) it show LOADING ... for 2 secs, thats all.
what can i do??
