Thread: Convert 3790/3760/3750 to 3490

From reading here and referred links, would it have been a good idea to backup NVRAM of 37xx prior to making change to 34xx?

Not entirely clear how to do so. I know that ldr.bin and txt file on sdcard can achieve this but unsure of syntax for full back up. Is there more info on this available?

rrgn,41,1:/41_backup.bin
or
rrgn,41,0:/41_backup.bin
First one will write to SD card.
