Sorry i was away from home today.I think the QPST-tool may be helpful, see these instructions and downloads.
Question is: which parts (partitions) from the working device would I need to flash for 'Phone image' and 'Boot image'?
update 1 - I'm going to try connecting the device to a virtual Windows and run the QPST tools. The drivers are included, and I've got a BOOT.img and SYSTEM.img from the Y550's original firmware. To be continued .
update 2 - I can 'see' the phone as 'Phone in Download Mode', but that's all. The tool insists on a valid .hex file format for anything to be flashed. If I try to rename Huawei's SYSTEM.img to SYSTEM.img.hex, it says it isn't a valid HEX-file. Which is true, of course. Do you have any insights?
So first things first: checking out the partition map of Y550 i think there is no calibration data stored so it should be safe to overwrite all of the eMMC. (If you issue "ls -la /dev/block/platform/XYZ/by-name/" you should see the names of the partition. More on that here.)
I found this guide that might come in handy as it uses a dd-saved image as you have. (I am not sure about the .hex format image the other tool wants...)
