Hi i'm calling all the people with same problem with me.
No Sound/No Wifi/No Call/No ICCD and coudnt downgrade baseband or use Ieraser.
My phone wifi was grey out tried everything on the forum but still stucked at bbupdater and ieraser,i tried unload the Comm Center and do ieraser but stucked at waiting for data(both ieraser v1 and v2)
Use bbupdater -v command return with unresponsive baseband.
I hope ppl with same problem with me pls discuss here for the fixing solution.
