I think you've missed seeing Posts #173 & 174 above. You seem to have formatted it incorrectly, i.e. you didn't set it as 'non-bootable' if you used the settings shown in your pic in Post #167. Try to format it again with correct settings as shown in the pic behinds spoiler in #174. The problem of it not booting may be as simple as an inappropriate format as pointed out by Fa_Pitar.

The SD flash to copy regions hasn't worked. The files you've zipped above are the 2 files i put there (Ldr.bin & update.txt), there should have been 2 more new files created if the commands were read (last_id.bin & update.log).
