SUFFICIENT TIME FOR THE PROCESS TO COMPLETE. Follow appropriate recommendations in
the Peacock thread.

Upgrading with DD-WRT

1. After researching build threads, use a good k2.4 (/broadcom folder) build under ~3648 KB
• See Firmware FAQ. Do not use files from broadcom_K26 nor broadcom_3X!
1. Upgrade from the DD-WRT GUI Administration->Firmware Upgrade
2. Perform the update and allow sufficient time to complete
♦ Although the router has 4MB flash, the Netgear partitioning and CFE limits the available
partition size to 3735552 bytes (3648 KB) for linux and rootfs combined. See the Peacock
Announcement for details.
♦ Loading a larger *.bin will fail leaving the router in TFTP recovery mode, to then load a
smaller file.

Revert to Netgear firmware

Netgear_WNDR3300
from the NA firmware you had.
Do you still want to continue?
Current Version V1.0.XX_1.0.XXNA
Uploaded Version V1.0.14_1.0.14
Where XX is a version number (typically 29 for refurbs, 45 for fresh retail models)
Ignore the Uploaded Version "V1.0.14_1.0.14" string, this is just the version the
original DD-WRT chk file uses so the Netgear firmware will accept the file.
