Can you put an iPhone 5s in DFU mode if it has been put in Lost Mode?

Nope. The Find My Phone loads before you can put it in DFU mode, and it is unbreakable at this time.

No. You can't bypass the iCloud activation lock. Some have tried with limited if any success at all. Take a chance. Best luck.
