I have now downloaded SE Tool2lite 1.1 and once again connected my phone. Just like xs++ it can identify my phone, firmware etc. So I have now use SETool to backup my GDFS once more. The interesting thing is that this backup is only 80KB. whereas the backup using xs++ was 100KB. Could it be that xs++ somehow accessed a part of memory that it shouldn't have? Which is the correct gdfs?
