There are two reasons why I have deleted this thread:
1. People who have DB2020 following this tutorial will kill their phones forever, DB2020 GDFS can't be repaired, not even with expensive software/dongles
2. The autor linked to a site that stole TopSony files
I encouraged you to open this thread again with PRECISE information so that people know which phones can be done.
Also you should write a PM to me directly instead of opening a thread with this issue. I could act instantly and you wouldn't have to wait for a reply for 4 days, like you had to now.
