can i downgrade iphone 3g 4.o to 3.1.3 without shsh blobs saved its a mb model
im pretty sure that mb models dont have ECID so they dont have or require shsh blobs.so yes you should be able to downgrade!
Pretty much as said above. iPhone 3G doesn't have SHSH blobs for anything less than 4.0. So go ahead and downgrade. Make sure you're using alower version of itunes such as 9.0 or bellow. And it's in DFU mode
