Bootloader 90.78 impossible to flash anything

Hi guys, i bought a milestone (About Phone says "XT702") from China, however i found out that u can flash nothing with this bootloader except in my case (the SGC_U2_01.26.0_USASHLSGCB1B2B5006.0R_PDS069_HWp2a_ 1FF.sbf can be flashed only...especially ONLY SGC sbf files can be flashed....anyways,

on the other hand i even tried to flash custom recovery rom via adb(deviced already rooted) and moto RSD...non of them works, via MOTO RSD it just says flashing fail and the phone does nothing if i flash other sbf files of another country same applies to bootloader!

Next i tried adb install the custom recovery(im able to root)...the phone reboots and jumps into the bootloader screen and below the version number it says error with some strange codes...im really upset on this device since i have been saving for it for nearly 6 months...i really hope someone can please help me....

I also tried to flash the vulnerable_recovery RAMDLD90_78.sbf but still can't do anything...

with anyother sbf files the phone respond doesent even say "SW update in progress"

Please help someone...your help will greatly be appreciated

The Powers that be should sticky this, along with the milestone overclock thread. Possibly the 2 most useful updates a milestone could have (until the unlocked bootloader hehe dream on)

it says signature verification failed
Installation aborted.

it says signature verification failed
Installation aborted.

Going to guess you get this when running the update.zip. Flash the vulnerable recovery again on top of the ROM you're using.

The root fails, it always says
"E:Can't open /cache/recovery/command"
Then after "Verifying update package..."
"E:failed to open /sdcard/updated.zip (no such file or directory)
E:signature verification failed
Installation aborted."
