I have a Z1s, Kitkat 4.4.4, trying to connect to a Lenovo laptop running W8.1. The problem happened after I tried using Helium to backup my stuff. The PC Helium program tried to get me to change my USB connection setting from MTP to PTP, which I wasn't able to (after selecting MTP option, it would freeze for 1 -2 secs then switch back to MTP.
Program never worked and now my computer doesn't even recognize my phone when it's plugged into USB2 port. Tried restarting phone and laptop in varius orders enough times to really annoy anyone. Tried 3 different cables, all of which work fine with another phone. Tried all USB ports on computer. Tried to reinstall drivers via Sony PC connect but can't because my phone isn't even recognized so it doesn't even give me the option. Tried to download xperia z1s drivers from sony but all it is is just the driver (Seriously Sony?! You couldn't even take the 2 minutes to include an installer?!) and I have no idea where or how to install them. Tried to do it manually via Device Manager, but couldn't figure it out, plus I don't think that's the issue. There's no device in Device Manager that resembles my phone to even do a driver update, cuz my computer doesn't even acknowledge my phone when I plug it in.
I think the issue has something to do with either or a combination of: Helium, MTP settings (which I have been searching for on my phone and online and can't find it anywhere. Supposedly it's an option in "Storage" section but I don't have an "Options" menu under "Storage"), my phone being encrypted.
I need to reset my phone but since it's encrypted, I must pull all the data from my microSD card cuz once the phone resets, it, nor anything else won't be able to read the card and must be wiped. That's the only way to unencrypt the SD card or phone.
Does anyone know where the MTP/USB connection settings are? No, they are not found under USB onnection settings that I could find. I really think it has something to do with that.
Thanks in advance!
