Wrt310n Debrick

[luciferxe]

The only thing I am having a problem with is finding this CFE.dll file. Is this really needed?

Thank you.

No it is not needed.

i also have the same problem with a WRT310N V2

i belive the reason is that the chipset is a hynix in the v2 of the 310 also its 4M


here is the info on the v2

Serial Num. = CSF11
FCC ID = Q87-WRT310NV2
CPU Type = Broadcom BCM4716B0KFBG CS0908 P20 E10186 N1 (BCM4716B SoC)
MIPS Rev = R2
CPU Speed = 300MHz
Bus = ?
Flash Type = Serial
Flash Chip = ?
Flash Size = 4MB
Max Firmware Size = 3801088 bytes
RAM Size = 32MB
RAM Chip = hynix HY5DU561622FTP-D43
nvram Size = 32kb
Switch = Broadcom BCM53115SKFBG (BCM53115)
Port-based vlan = ?
802.1q vlan = ?
Ethernet Port Count = 1-10/100/1000-WAN 4-10/100/1000-LAN
Wired Standard = IEEE 802.3/3u/3ab
boot_wait = ?
bootloader = CFE
Flash Card Socket/Type = No
SD/MMC Mod Support = No
MiniPCI slots = No
PoE = No
Power = 12V/1A
Color of LEDs = ?
Size = 8.0" x 6.3" x 1.3"
USB = No
Serial Port = Yes
JTAG Port = Yes

how can i get this to detect

This could be the memory map issue. IR length might also be a problem.

I'm trying to backup a Cisco Valet Plus, which is supposed to be the same as a WRT310N. I'm getting similar results as well. Here's the output:

This is the output when hooked up to the JTAG pins. I tried reading the SPI flash directly, but I appear to have bricked that one. I have another unit, and the output is the same (JTAG pins, I'm hesitant to try hooking up the SPI flash again ).

The flash chip is MX 25L3205D

I have not tested WRT310N V2 myself. So I am not sure what the problem could be.

[Teddy Boom]

I can send you one, it would be great if it could be supported.

Thanks

Is this JTAG but with SPI flash? That will be interesting to add.

Yep, check your pms for a picture. I lifted the flash, and out of circuit it reads and writes perfectly well. In circuit it won't ID, and is really easy to brick...
