Find out the device version ...
To check the hardware version of your TP-LINK device, flip it over and look at the sticker on the bottom panel. In the field where the serial number (Serial Number) is indicated is the character string “Ver: X.Y” (for example, Ver: 1.0), in which the X is the hardware version of the device. That is, if the line looks like this - “Ver: 1.1” - this means that the hardware version of the device is V1.
If you did not find the version designation at the end of the FFC-ID: then you most likely have V1.x

Hello! Sorry, maybe I created a separate topic for nothing, but I just can’t find the answer to my question (
I have a router TP-Link 3420 v2.x, flashed OpenWRT firmware in it wired serial-port and it saved me. But after each flash it, we got kirpich.Posle activate lights only light network and the unit does not respond to that. I understand the problem is that fell off the loader. Google, suggested that it is necessary or vypaevat flush memory and sew programmer or via JTAG.Interesuet second option. Here the question is: what kind of need a cable for it and how to proceed in the whole process of connecting. Information took so from here:http: //wiki.openwrt.or...toh/tp-link/tl-mr3420.Help if you can! Thank!

There is a router mr3420 on board is Barrier Breaker (r44952) assembled from the branch Branch.
There is a need to install the wshaper package, but when I try to install I get an error
root @ OpenWrt: ~ # opkg install wshaper
Installing wshaper (1.1a-1) to root ...
Downloadinghttp: //downloads.openw...shaper_1.1a-1_all.ipk.
Collected errors:

Which way to dig?
Understood =) it turns out the signature keys do not match, but you can install with the option--force-depends looks like this:
opkg install --force-depends wshaper

Not for the mr3420.v.2 router above openwrt. I put, usb immediately connected but the Internet did not want to broadcast. Only local network plowed. And it was a chore.

in the webinterface itself there is no Russian language pack and in the repositor only Anglissky lutsi.
connected both modem. hilink E3372 and anydata ADU-520A. I just don’t know if 4G will work. There is only gprs-umts-evdo, and now 4g will not be checked.

Rollback from OpenWRT to the original TP-LINK TL-MR3420 firmware

You can flash the router in original way after OpenWRT using the tftp or MTD method, but in no caseDO NOT PASS through the Web-interface . Otherwise, you risk getting a "brick" instead of a router. The name of the firmware should not contain the word "boot"
Routers of the second revision V2.X being flashed by one of the latest, factory firmware support recovery via a tftp server. Therefore, before flashing alternative firmware, always update your native one to the latest version. If it was not possible to flash through tftp, then there should be no problems with MTD.
Firmware with TFTPD32
Download utility Tftpd32 HERE
Looking for firmware for your hardware revision intended for recovery. Such firmware does not contain the word boot in the title. Change the name of the firmware file: "mr3220v2_tp_recovery.bin or mr3420v2_tp_recovery.bin", respectively.
Connect the router to the computer using a network cable and change the IP address of the network card to 192.168.0.66, mask 255.255.255.0.
Disable antivirus and other firewalls present in the system.
Throw the image in the folder with the program TFTPD. Run it as administrator. When you click the Show Dir button, the file with your firmware should be listed. No need to configure anything.
Holding the WPS / Reset button, turn on the router, after loading the image, release the button and wait for the reboot.
After that, do not forget to return the receipt of the IP address automatically.

MTD Firmware
Download programs PuTTY and WinSCP
Open WinSCP, select SCP protocol, address 192.168.1.1, port 22, User name: root, Password that was set earlier, click “Login”.
We answer all vague questions and see a window with files on your computer and on the router. Next, take the native firmware, rename it to code.bin and throw it on the router in the / tmp folder. Close the program.
Open PuTTY, select the SSH protocol, address [email protected] port 22, click "Connection". We type the password that was set earlier for root. We enter the router and type the command for its firmware:
mtd -e firmware -r write /tmp/code.bin firmware

You can do everything in one PuTTY by running the following commands:
cd / tmp
wget http://www.example.org/code.bin
mtd -e firmware -r write /tmp/code.bin firmware


P.S. Attention: if you see the error "Writing from /tmp/code.bin to firmware ... [e] Failed to erase block" after flashing with the mtd method, do not turn off or restart the router, otherwise you risk getting a "brick". Probably, you used a version with a "boot" for flashing, for example, mr3420v2_en_3_13_27_up_boot (121206) .bin, try flashing with another version.

P.S. If you did not find the firmware without "BOOT", then before executing mtd -e firmware -r write /tmp/code.bin firmware you need to run the command
dd if = code.bin of = tplink.bin skip = 257 bs = 512
which will cut the boot, ie the first 0x20200 bytes from the original firmware. After this, the name of the firmware will change and you will have to execute the command
mtd -e firmware -r write /tmp/tplink.bin firmware
