I'm not sure if this has been already asked but here goes: I followed the guide step by step (and thus updating my bios to version 2.02 now the next point of the guide is that I need to have the same version of bios to flash a modded version. So I'm now on v2.02 but the only modded ones attached are the 1.03 and 1.04. So whats the point in updating to v2.02 first? And do I need to downgrade now in order to flash 1.05? Thanks EDIT: Found it, its in this thread: http://forum.techinferno.com/lenovo-ibm/2874-lenovo-y400-y500-unlocked-bios-wlan-whitelist-mod-57.html#post49733 Hope this helps others
