That is so weird. So you cannot get it to show fastboot usb?? If so, then I don't know what you can do. You need to have communication to restore with RUU. I know some people do JTAG, but considering you can buy a used One S for around $120, it may not be worth fixing. Most people I know charge around $75 for fixes so I may not be even worth it. Hopefully someone with more knowledge can jump in this thread.
It's really strange beacuse with this metod it works a few times , but i hadn't enough time to install the rom
Before you begin with your computer:
- go into recovery
- advanced
- reboot into recovery
If it reboots straightaway, you're ready to go. But it might wait, and offer you to root your phone. Do that, otherwise it won't work!
I would also restart the computer, just for a clean start. I also wiped my phone once again (factory reset).
On your Mac:
- make sure your rom (*.zip) is inside the platform-tools folder (this is inside the android sdk, where adb is)
- your phone should be disconnected and in recovery mode
1. open Terminal
2. type: cd (press space)
3. pull the platform-tools folder onto the terminal, press enter (this is here: /android/sdk/platform-tools)
4. type: ./adb kill-server (enter)
5. type: ./adb usb (enter) -> now it should say that "error: device not found"
6. connect your phone to the computer with the usb
7. type: ./adb devices -> it should show your phone, recovery mode
8. in your phone enter sideload mode (either in advanced, or in install zip option)
9. type: ./adb devices -> check if your phone is connected in sideload mode
10. type: ./adb sideload + <full name of the rom, including .zip, without brackets>
It should work, for me everything went perfectly.
