thanks for your help. your solution seems to be fine but I guess the failed update has corrupted the first 0.5MB on the flash device :(
It seems I would need a full dump of a working machine to compare the data of the first 0.5MB right? Do I have any chance to get this solved without a full dump? I hope someone can help me. 2012/12/6 Andrew Goodbody <[email protected]> > On 01/12/12 21:11, Daniel . wrote: > >> So at last I just need to know now how I can merge the needed >> decompressed files back into a flashable ROM file. >> > > No, this is the wrong way.
