Backing up/flashing MEFW

Backing up/flashing MEFW

khenglish's picture

I'm trying to figure out how to get a full ME FW image off of a computer's flash ROM. FLUpdLcl.exe does not perform a full image backup or flash. It leaves out the system specific configuration data, and just adds padding at the end of the flash image to make the file size about the same. Fptw64.exe does perform full backups and flashes, but it requires permission from the flash descriptor by either general read/write permission, or through the flash descriptor override. The former is rare to have, and the latter I just don't know how to do.

Is there a some method using either of these utilities to retrieve and flash an image? If not, is it possible to enter commands through the LMS service directly to do these things?

I don't care if the method is complicated, I just want a working method.

Thanks for reading.

Hi - if the FW can be backed up, I'm not aware of this capability. You can build your own FW if you have a specific tool (and you need permission to get the tool as well.) I will need to research this. Gael

I actually do have the tool to build a FW. It would be preferable to be able to back up and edit the system specific image, but it's not necessary. What I really need is a way to flash the firmware that does not require permission from the flash descriptor, or a way to set the flash descriptor override that works consistently between different computers.

Ok - there are two ways to backup the ME Firmware: 1. Use the FPT tool fptw.exe -d image.bin 2. Use a Dediprog (Here is an example in a blog.)

Interesting. Thank you for looking into this.
