Thanks friends... i've flashed my phone except "W550_CDA102426_9_R2A_Generic_EUROPE_1" file. It's a zip... Do i use da zip??? or extract it? but after flash, my phone doesn't start. usb cable connected and phone is charging. When i start phone it says "Please wait" with a weird colour. Now what should i do? Forgive me if i screw up anywhere. :(
