I Have the same problem with my w580i initially it was blinking red on infra red so i decided to use D ultimate unlocker to repair the erom and GDFS reconstruction. Both this proceedures were finished successfully, but when i am trying to flash my phone with setool or xs++ i can't my phone is keep getting disconected after writing 120 blocks from 460.
Anybody have any idea what should be done. Also to add my phone was not recognised by c button on any of the tools but after repairing it wih D Ultimate it does.
Any help would be appreciated!!!!
low battery, make sure it is fully charged and try again
