when I tried to unlock bootloader, this message is what I get.. What is the problem now?
try to unlock your bootloaders if your EROM version is R9B031
There is at least one report from someone who bricked his device.
in the s1tool first if your phone has an appropriate EROM or not.
You can also dial *#*#7378423#*#*
go into Service info > Software info > "S1 Boot Version:"
Also check under Service info > Configuration if "Rooting status: Bootloader unlock allowed:" says Yes or No.
we'll have to wait for an updated s1tool which is capable of patching the newer phones.
Until then this method is not working anymore on those.
Please post your version if it was working for you.
So far these EROM versions have been reported to be working:
