iPhone 3 - with charger ( read description )

Won’t bootup past the apple logo. Not to sure why it is having issues. If I could get it on I could reset it and remove my iCloud from it so unfortunately it’s locked but if u know phones and how to fix this problem and then can reset it I can further keep communication so that I can remove my iCloud from it. Brand new in box it’s going for 1000$ Figure if he cool with a fair offer or just asking price *
