Hello guys, I need some help. I have already backed up my SHSH blobs on 3.1.3 I recently updated to iOS 4.0 = bad choice. I want to downgrade back to 3.1.3, I have already tried the TinyTSS method here but iTunes returns a 3194 error when verifying. It looks like the TinyTSS is not doing its job. Then, i tried tinyumbrella, which had a TSS server built in. I placed my SHSH file in its cache folder. Same problem with iTunes. I have tried this on iTunes 9.0.1, 9.1 and 9.2 and all problems persist. I have done all this in DFU Mode. Is there any way for me to get back down to 3.1.3? Any success stories here? Thanks in advance and I really hope I get some help here.
