Question [Q] Windows Phone 7.5 Update on Omnia 7 error code 800180031

Hello everbody!!

I have a Samsung Omnia 7 (8GB) (T mobile Deutch), I used [CAB] Official WP7 Updates List up to WP 7.8 + ALL LANGUAGES complete + OEM updates from this post:,
I succeeded to make the update of my phone from windows phone version 7.0.70004.0 to version 7.0.7403.0, using WP7_Update_Cab_Sender.bat,
but when I come to make the update from the later version to 7.10.7720.68, the operation stops and shows an error code 800180031 saying "not enough space in os partion", I raised the amount of space using Zune but it says always the same thing, please tell me how to overcome this problem.
thanks in advance
