backup is allready done, i allready played a bit around with the firmware backup/modify/flash tools with no problems at all , changing the themes a bit
the larget chip on my board is the 'Samsung 628 / K9HAG08U1M PCB0' , so this should be the memory chip which needs to be resetted ?!
i want to change from vertical to horizontal to get some more readable characters for the files, they are shortend too much
