Flash firmware TP-Link TL-WR741ND rev 4.24

[Zuffa Jan]

tento navod pouzivam u WR842ND a openwrt, nie je to sice rovnaky typ ale postup by mohol sediet.


Using a tftpd server

The following procedure was tested with a TL-WR842ND.

Enter failsafe mode:

remove the power plug from the router
press and hold the RESET button
insert the power plug
release the RESET button
Some seconds later no LED besides the one for USB (and maybe for attached ethernet ports) should be lit.

The device now uses the IP 192.168.1.86. It repeatedly tries to download a file named wr842ndv1_tp_recovery.bin from a tftpd server with the IP 192.168.1.66. You can verify these continuous requests with a network sniffer (e.g. tcpdump or wireshark).

The following steps will serve an openwrt fimrware image to the device:

download an appropriate firmware file (e.g. openwrt-ar71xx-generic-tl-wr842n-v1-squashfs-factory.bin)
create a symlink or rename the file: ln -s openwrt-ar71xx-generic-tl-wr842n-v1-squashfs-factory.bin wr842ndv1_tp_recovery.bin
configure the static IP 192.168.1.66 for your local ethernet interface
connect your computer to one of the LAN ports of the router
install a tftpd server (e.g. atftpd)
run the tftpd server and let it serve the directory that contains the above firmware image: atftpd -no-fork -daemon FIRMWARE_DIRECTORY
the router immediately starts to download the firmware image
after some time you will see all LEDs flashing once followed by a normal restart of the router

Zdravím,

povedlo se mi bricknout uvedený router. Flashoval jsem jej na DD-WRT, což proběhlo v pořádku, ale při návratu k originálu jsem klepl o revizi vedle a router teď na mne bliká všemi ledkami a jinak nic.

Moje jediné vybavení je PicKit3, PC se sériovým portem a nula zkušeností v této oblasti.

Našla by se prosím dobrá duše, která by mi poradila, popřípadě za úplatu router oživila?

Díky za jakoukoli radu, facku už jsem si dal.

Milan
