Sorry to be dragging this post on...
I am about to take the dm520hd in to have the soldering done for the holder to house the Japhar sim.
Following the instructions, I was trying to load a Japhar image which was
openpli-enigma2-7star-dm520_Japhar.rootfs.tar.cz being OpenPLI 7*.
It failed with 'Boot image is too big'.
Should I have the sim holder done then try again with the sim installed or find a smaller Japhar image (if there is one)?
Please advise
