Problem when update firmware 4.0.2 to 4.1 without update bandbase - GSM-Forum

demol3 · 12-12-2010, 21:47

I've downloaded iOS 4.1 from redmondpie website and update it with tiny umbrella. but it appear error 1604, then i tried again with TSS server on, and iREB 4.1 to put my phone in DFU mode. after I successfully updated the firmware to 4.1 and error 1004 ( sign of not update bandbase and keep it in 1.59) the phone can't get out of DFU mode and tinyumbrella cant recognize my phone. Itune recognise it in recovery mode but the screen is just black. I've tried others software but it doesnt appear to recognise my iphone. I also tried to hold home and power button for 5-10 seconds.
