GooD day,

 

During process to jailbreak my NEW apple tv 2g 5.0 , at stage no 4 - during itunes restore i rcvd error 1604.I passed over error and continued .After completion of jailbreak process and tethered boot , my apple tv starting without any changes ( only that is tethered now ( NO LOGO, NO NEW ITEMS , ETC). )

 

i TRIED TO RESTORE IN ITUNES TO FACTORY SETTINGS BUT I HAVE RCVD ERROR 21.

i TRIED TO CHANGE USB CABL/ USB PORTS WHEN STARTING BOOT TETHERED PROCESS , BUT STILL NO CHANGES.

 

JAILBREAK OR/TETHERED BOOT IS NOT CORECTLY DONE? OR I MUST DOWNLOAD/INSTALL ATV FLASH IN ORDER TO HAVE ALL ITEMS/LOGO/ETC? or i must start again jailbreak process?

 

PLEASE HELP ME TO COMPLETE JAILBREAK OPERATION.
