Confirmed flashing w550 using cruiser caused network problem
 

I've tested flashing w550 with white screen problem or even upgrading with cruiser v12.02 always causing lost in signal/network, Here is the file i used
W550c_CXC1250086_China_R4CA004_Brown49.cw55sw
W550i_CXC1250032_APAC1_R4CA004_Brown49.cw55fs

I didnt noticed this kind of damaged caused since i usually reasoning with customer that we cant check the phone's condition before since it is white screen, so network problem is not our responsibility. But this reason become almost everytime for only w550 handset, tried flashing back with setool n mtbox but still network loss or not stable. Any help?
