hi need help
I decided to roll back to the previous build for windows 10 mobile on my lumia 640 which need me to roll back to windows 8.1 After downloading the windows 10 update it began to install, after it was almost finsihed it bluescreend on me and became stuck in a bootloop. Hooking it up to WDRT again i got it into flash mode. while flashing the phone dissconnected itself. it did this a few times and now it' not turning on at all. WDRT sometimes still detects my phone and wants to do a 2,93 MB ''emerency flash'' but this doesn't work either.
please help me.
