hey, first of all i want to apologize on my poor english grammer . it's been a day with planty of experiments to downgrade my iphone 4 ios 4.1 to ios 4.0.2 because i want to "carrier unlock" it. after i saved my blobs, and getting into DFU mode, i need to press "start TSS server", right ? when i'm doing this it's just keep showing me "accepting tss "something"" and nothing else happend, i waited roughly 2 hours. and when i'm getting into cydia, i see that it writes me "this device has a pending TSS request" now, i'm not an expert but i think this is my problem any ideas ? and to the second question, if i want to restore my device to factory setting witout updating my ios to 4.2. how do i do it ? thanks from advance for all helpers!!! daniel.
