orbit do not boot, do not flash

[ohs]

Hello,

i am searching for a solution of my problem:

i updated my orbit with the new mossis ROM and everything was well, and i used my orbit after this update!

Yesterday i Reset my device and after this the orbit dosen't start again!
After showing the bootsplash the device hangs
So i try to flash the device again:

first i try this:
- start the bootloader manually (voice button + reset)
==> shows: IPL 3.04.0001
SPL 1.11.0000

- starting the ROM Update Utillity
==> the screen of my orbit is grey and shows the update bar (0%)
==> RUU shows the following mesage: ERROR[300]: INVALID UPDATE TOOL

(i used the original german o2 update file)

second try:

update with the SD-card:

- SD-card (512MB) formated with FAT32
- copy the image file xxxx.nbh to the SD-card and rename it to ARTEIMG.nbh

- start the bootloader manually (voice button + reset)
==> screen: Checking SD contens
==> Update SD Image?

- bushing the volume down button

==> screen is red green blue and shows IPL 3.04.0001 and SPL 1.11.0000
Update flash do not start!!!

if i try this sd-card based update with the RUU_uspl_signed.nbh file, the device bootloader start and update the ROM

have anyone a idea???:confused:
