I have a netgear_wndr3700-v4. In the process of un-bricking it, I did :
nand erase 0x6c0000 7485746
... but the "size" was interpreted as hex (~122 meg), so it did :
NAND erase: device 0 offset 0x6c0000, size 0x7485746 ath_nand_erase: 0x6c0000 933
I think this erased caldata_backup , which is at 0x1fc0000-0x2000000
Do I need to restore caldata_backup (from caldata) ?
Also, when I flashed the netgear factory firmware, I got tons of error messages, such as :
Empty flash at 0x0553fc3c ends at 0x0553fc40 jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x05540000: 0x7f7a instead
Everything seems to be fine w/ OpenWRT, but I wonder if I broke something.
Do you I need to fix anything ?
