Flashing such dumps is far away from reality in any case right now. It won't be possible to do that until we have a full kitchen, you can't just flash these back (usually). What I can do with these files is try to pick the right files and upgrade those, to see if I can get some results. However, upgrading the files I need 'in place' stops my device from booting, it seems I also need to update some files from the XIP section, which I have not been able to extract so far, so no go.
I'd flash to the G7 ROM in from the other thread, however, it does not include any language files, and as my own ROM is from May or something, that seems like a bad idea. I might attempt it, but I'm a bit scared to.
In other news, it seems my v1 compat library did work with the combo of drivers that gave me garbled output. But I can't really test that until I get a ROM with the proper drivers on my device.
