Hope someone can help.
MY Unit is Rns 510, 1T0 035 680 R, Sd Drive, C14, Hardware H27, Firmware 6276, Map upgraded to V13.
2 months after map upgrade lost all sound put back to factory Settings sound back on sat nav only then lost again.
Friend had similar problem put right by reload of firmware so tried to reload 6276 firmware but stopped with error “ecuorder.txt" – "error reading hw vers".
Tried “swl_fix.iso” this also failed with error "ecuorder.txt" – "no HW mapping file".
Tried again to reload 6276 again failed also with error "ecuorder.txt" – "no HW mapping file".
After some research and looking at firmware file scripts, looks like drive is corrupt and needs reformatting or replacing but FW 6276 only updates existing files, looks like I need FW 6270 that does a new install with a disk format of 3 partitions.
Unable to find FW 6270 due to it been held back because it can brick C12 and earlier chipsets.
Is it possible for someone to help me obtain a copy of FW 6270 or give any assistance with a workaround or alternative method?
Will a 5xxx (901) version with format install on C14 unit and can it damage C14 chipset (install 5xxx then update to 6276?)
