Default Help. Need last 4.1.2 zip


Unlocked XT907

I need to restore my phone to stock through stock recovery.

I screwed up updating to 4.4.2

I can get to stock recovery; KDA20.62-10, and I can "apply update through sdcard" or adb, but I get the following error when I try to install either of the two (.18 or .30) blur files.

file_getprop: failed to stat "/system/build.prop" no such file or directory
Installation aborted
I believe it's because I'm still on the old recovery, not the new one. So I figure I need to flash the last version of stock 4.1.2 through recovery and start from there.

I can't find it though. Been googling it for an hour.

My computer (Win 8.1) won't recognize my phone so I can't ADB, fastboot or RSD Lite.

But I can pull my sd card and insert it in my computer to add zip files.

Links or ideas?
