i tested it with the newest German O2 ROM. You must install the O2 ROM on youre device and backup the OS ROM with awizard (start command line under windows when youre device is connected, start awizard, at first option e then u and then b). After this you can edit the nk.nbf file with a hexeditor how Yunshen in his thread wrote http://forum.xda-developers.com/viewtopic.php?t=63505 and Hard Reset the device.
My Storage was after this only 40MB instead of 44MB before. I have not testet my Neo more with this rom because i want use a newer ROM with Aku2.3 and the German O2 have only Aku20.
After recover and hard reset my Neo i have 4 MB less then before. How stable the system runs i cant say. It was very fast but i have testet then other ROMs and have now the orig O2 ROM without pagingpool in use because i have not enough time this days for testing.
