One important detail that needs to be addressed. I believe that the Navitel model that janch flashed uses resistive touch like the E700 I flashed with the same firmware. I got my hands on a E707 Magnetic with the goal of converting it to WinCE with the aforementioned firmware in post #1, the device started bootlooping... and after one hour of sweating profusely with the worry in my head that I had bricked a customer's device, I found a firmware suitable for E707 Magnetic with a capacitive touch. So please check what kind of touch you have before flashing.
