How do you reset an iPhone 4s without a passcode or iTunes I have an iPhone 4s running iOS 9.3.5 that i would like to wipe and reset. I do not have the passcode. I also do not have access to iTunes. My only computer is a Linux Ubuntu 16.04. I have tried to run iTunes under Wine and PlayOnLinux as suggested in some other posts, but neither of those worked. iTunes wouldn't run under Wine and PlayOnLinux didn't have USB support. 
Installing Windows to a new partition and running iTunes from there is an absolute last resort that i would like to avoid. I am also not reasonably close to an Apple Store.
Is it possible for me to reset this phone without doing that, and if so, how would I do it?
You can wipe your phone remotely by using the web-based iCloud Dashboard, using the Find My iPhone feature. You can add a trusted phone number through the same interface, and use that phone number to receive the code to wipe your phone.
