Hello.
I have a problem with Umi Plus E. This same problem have my friends with this cell phone too. It is completely dead. When you connect to its charger, the red LED is shinning, but nothing else is hapening. I tried to connect the phones to PC by USB cable. Usually there is a clicking sound from Windows PC when you connect cellphone and Windows detects it, even if the cellphone is turned off. In my case no sound when I connect it to PC. It is same for the rest of 3 another Umi Plus E which I have here. I disassembled all those Umi Plus E, then reconnect their batteries. Still same. I also know when you disconnect battery and connect cellphone into PC by USB, there should be the clicking sound when Windows OS detects a new device. In my case still no sound which showing a detection of the cellphone, only red LED is shinning constantly. So it seems there is a problem with main board. I also tried to use SP flash tool for reflashing ROM, but I can't because cellphones are not recognized. It's interesting that all those Umi Plus E have the same problem.
Manufacturing defect after 10 - 15 months of using? |
