Just keep poking around in it...
The FFU-image you selected for profiling does not have a supported OS-version. Windows Phone Internals needs to extract files from a supported OS-version. You need to select such donor-FFU. If necessary, you can select an FFU-image for a different model.
what should I download for Microsoft 535?
Hey Heathcliff74, Please is there a fix to turn off reset protection after what you software has caused to many Lumia phones? It be nice if you could build a program that does a cross scan between each device IMEI and upon Microsoft Reset protection status site that states on there site that is off which will force it off on a phone that should have been off? Or at least give us something were we can disable Reset Protection. The bypass solution is a pain even though that works. Though not idea to do for any owner of a Lumia especially for us Lumia 950/XL owners.
This software is a "proof of concept" tool which uses dangerous and largely untested techniques on Windows Phones ("Target Devices"). By using this tool the target device may start showing unstable behavior and crashes. There is significant and real potential that irreversible permanent damage will occur on some devices. As such this tool must only be used against target devices which it is acceptable for such damage to occur (for example retired devices used only for test purposes). This tool should not be used against target devices, which are intended as your primary means of telecommunications, because in some circumstances you may not be able to place calls (including calls for emergency services), or you may experience increased data charges. Use of this tool may void the warranty of any chosen target device.
First of all, thanks for the hard work you've put into this. Quick question: If you unlock the bootloader and gain root access, can you remove root access and re-lock the bootloader? (I'm assuming you can, but I'd like to verify). I like the fact W10M is a secure OS. I would only want to unlock the bootloader and gain root access on a temporary basis.
