Error 28
The problem is a bad dock connector on the iPhone. Must change the connector. If you have tried almost everything, reset the logic board leave uncharged for 2-3 days or remove battery for an hour. If doesn't work, the flash memory is damage .

yes you can simply put phone in PWN DFU Mode using ireb and then restore stock 4.1
if you have Safe S/N then update your phone's baseband to 6.15 using redsn0w...
