Hello Everyone,
My problem is still not solved. I have Dlink DIR456U wireless routers at 5 locations. All routers date expired on 31-12-2012. I bought in November 2012 from local dealer. How to make its date 2013 and above? If not possible, means throw all 5 routers? It means the routers are useless after 2012 year? All my customers are desperately waiting for the date update.
Please help me to keep the routers working.
Thanks.

I don't understand what you mean. A 3G router hasn't any expiration date. Probably it may refers to SIM expiration date so you have to handle this stuff with your 3G SIM local provider.

Did you contact your local D-Link to have a new firmware update as suggested previously?

Can I flash this firmware completely through the programmer?
Can anyone have a full dump of flash memory for firmware with a programmer?

Which model/type of programmer?
Why do you need a programmer? Maybe is your router bricked?

I give it to a service center where they can flash the chip with a programmer.
I connected via UART, the router hangs on boot U-Boot, and after the reboot nothing changes. It is impossible to forgive him through other regimes. There is a suspicion that there is a problem with U-Boot, and you need a firmware from U-Boot to flash it through the programmer.

DIR-456U A1 SoC is Ralink RT3050F (MediaTek) just like DIR-300/600 Bx.
Usually U-Boot performs switch to Recovery Mode on flash content integrity fail. But it's better to have a serial log to understand what happened.
Have you tried to enter in Recovery Mode via emergency HTTP web interface?

I tried it, it does not come in, since the connection does not rise. The router, when turned on, hangs on the line(when connected and viewed through UART):
U-Boot 1.1.3 (Jan 12 2011 - 19:40:43) (ALPHA)
SVN revision: 480
Target board: WHD-RV01

while the power indicator and the globe are on on the router. When the LAN cable is connected to the LAN port, the indication does not light up.

Is it possible to flash through the programmer the firmware from the DIR-300 router rev.B3 (judging by the data they have identical CPU/RAM/Flash) in order to restore the U-Boot in this way and then flash through the uart the normal firmware for this router?

Why your device is bricked in this way? Have you failed to upgrade a firmware?

I think it's better to use DIR-456U A1 original D-Link firmwares.



DIR-300/600 Bx is supported by both OpenWrt & DD-WRT!
Added in the previous post DD-WRT Wiki and U-Boot Reference Manual links in addition to OpenWrt Wiki already present.
U-Boot has a command shell (also called a monitor) in which you work with U-Boot commands to create a customized boot process. Maybe there is something usefull to solve this case...
