Thanks for the images, but a question: From where do you acquire the scatterfile (or rather, how do you generate it)?
Sure. I suppose I didn't describe that well earlier in the thread.
Back when I first worked out the process to root, I used this '
Wwr MTK tool' on Windows to generate a scatterfile that's compatible with SP Flash Tool. It has a great deal of functionality, but can be confusing. iirc, not having root, I had to follow the convoluted process documented there to do something like first generate a partial scatterfile, then use that to readback the whole device from SP Flash Tool as one image, then get Wwr to analyse that and generate the full scatterfile. Just follow the steps there. Or, I suspect that by starting from a rooted device, you'd be able to use a different function of Wwr to read the partition layout directly from the device to generate the scatterfile.
Let us know how you go! =)
Second, when you use spflashtool to extract the boot partition, how do you remove padding from the end of the image (the actual boot image does not fill the entire partition)?
Haha, good question; I don't know how to do that yet. There is a function in Wwr for that, iirc, but the free version startup wait time is too annoying to bother. I think Wwr is just wrapping an open source partition editing binary for that though, so I suspect you could Google for like 'linux strip empty space from partition image'.
