This phone was stuck at Haier logo. I think this is W718J because it came with android 4.2. I tried a factory reset and now the phone cannot boot at all. No logo, no ability to get into the reset area with volume down and power button. I have tried more than one rom and tried to get the phone working with SP Flash tools but run into errors every time. I have installed the drivers and the pc recognizes the phone in the ports section of the device manager. I have tried many roms, and set the scatter file and then during the download process I get various errors. I have researched this problem for hours on this website and others but think I may doing something wrong. Can any one tell me the exact procedure to fix this phone? And do I need to have the sim card in the phone during these processes. Thank you in advance.
