Member: 523496 Status: Offline Sonork: ammachis Thanks Meter: 76 | retu provides power to all other ics if it is not there or if u replaced it with a bad one phone will dead ..If the phone is working before removing the retu and if it dead after fixing a new one it will be dead untill you fix a good one...and one more thing man If you want to be an expert hardware technician you have to show some courage be ready to take some risks...all the best You can take retu from the following very models.6085,3110c,6300,n70 72,etc.Ask the permission of customer before removing such ics ALL THE BEST..... |
