这些步骤也可以用来刷新OpenWrt（当你想升级）。

如果您对我们的销售你可以回到你原来的固件已经使用过的不满。为此，请使用以下命令：

cd /tmp
wget http://www.example.org/original.trx
mtd -e linux -r write original.trx linux

Replace the file

original.trx

with the filename of the firmware you like to install. This will erase the flash (-e linux) and write the new image. The -r will reboot the router after successfully writing the file.

If you get a error message on the above

mtd

command like "no valid command given" you are using an old version of

mtd

which doesn't support the

-r

or

-e

parameters. Download a newer statically compiled version (

mtd.static

):

cd /tmp
wget http://downloads.openwrt.org/people/wbx/mtd.static
chmod a+x mtd.static
wget http://www.example.org/original.trx
./mtd.static -e linux -r write original.trx linux

TIP贴士: PLEASE READ - Common mistakes thread section 2 also. It describes when you should use the

openwrt-brcm-2.4-squashfs.trx

image.

If you only have a Linksys

.bin

firmware file, this is not a problem, simply cut off the header before using the commands above:

dd bs=32 skip=1 if=original.bin of=original.trx

TIP贴士: If your replacement firmware has a web interface, remember to flush your browser cache, sessions etc. This will avoid misleading 404 errors.

Since White Russian RC4 you can use the webif to go back to the original firmware. The webif automatically recognizes a firmware image uploaded in BIN or TRX format and converts it accordingly.

• Load the webif in your web browser and goto the System / Firmware upgrade page
• 确保清除选中的JFFS2文件系统的分区
• choose the BIN or TRX firmware file (downloaded before from the manufactures website onto your PC)
• click on the button upload

The other way you can use is the TFTP method. The TFTP page explains how to install OpenWrt via TFTP, but this method should also work for other firmware.

/!\ 注意: On many versions, the TFTP server is only able to accept smaller firmwares at bootup. Firmwares that are over approximately 3 MB will fail with a

no space

error. If this happens you'll need to either use a different firmware or reflash using the

mtd

commands above instead.
