I don't know how often I've got to say it, until people believe that DB2020 GDFS can't be repaired.
The only thing you can do is to sell the components...
It depends on the phone model. Phones supported by Se Tool cracked and USBSmart 8.4 can be repaired without having a box.its true you cant write new gdfs by setool2lite and other flash program same it.if you want to write new gdfs (db2010.2012) you must use from box program.
