Subject: How to recover 741N, killed updating jffs2 over SquashFS?

Hello everybody! I would like to update the firmware on the router, but accidentally threw the image with the wrong file system (the SquashFS was, and threw JFFS2). The router reboots and more normally not turn on, turn on the power when all bulbs light up, faded out, then some time flashes gear and all the more, as I understand, nothing happens it tries to load and then catches the mistake and hangs. I tried to connect a cable to all ports, and nothing else. "
Tried different teams via telnet to achieve access to the web interface. But nothing worked. Of the latter, he did - to reset all settings to the default command mtd -r erase rootfs_data for jffs2.
Now, the power indicator lights and all ports. Icon system, wi-fi and padlock - no (

I understand only now soldered? Or are there other options? Since no longer connects to telnet. And the lights are on in the static mode and all.

Thanks in advance for the answer!

When enabled, of course, defines the port where the cable is inserted - just 1c, and then light up on lamp + on all ports. And so it hangs

MANUAL OPEN WRT
Turn off your router
Mount it in the settings of your network card a static IP in the range of 192.168.1.2 (make sure that the computer is connected to the first LAN port of the router)
Turn on the router
As soon begins to flash 'SYS' LED (signaling system boot), press and hold the button on the rear panel 'RESET' (you can also use 'QSS' button on the front panel 11)) until the LED 'SYS' flashes very quickly.
After that, you can open a telnet console to the address 192.168.1.1. Without a username and password.
Set the root password:
Dial: passwd root
enter twice the password: password
To activate the SSH connection through the console, type the following command:

Hello, Is it worth it to change the standard firmware openwrt something to improve or not ???? And what are seen bugs on openwrt ????



Rep: (283)
* DENiX123, I changed and I love I have is 14 version, bugs are only available from the web interface, supposedly it is impossible to remove the modules they lost but they did not disappear from the memory of the router and take up memory, so the same is true a couple of times dropped the default settings, as well as Useful firmware and very Advanced differ in the standard.

And before setting off on a read. Page which binarnk as they are called there for the first 2 firmware Photo and the second for the upgrade version and do not confuse the file system of the router.
And after installing the firmware web interface place manually via a telnet.

Maybe someone will be useful infa.
I have a 2 router 741nd from Kyivstar, one version 4.20 drougoy 4.24.
On a standard firmware COP from the TP or native-link limp recoil velocity in a single-threaded mode, the router is clocked at return jumps from 40 to 60 megabits that were unacceptable. Admission was almost stable in single-threaded mode, but sometimes it is sensitive to "float". Multithreaded stokovvye issued maksimlnuyu stitching speed.
Routers were stitched OpenWrt version of "Barrier Breaker 14.07". The situation znachitelbno improved efficiency in one flow was in most at the maximum speed and to be stable but sometimes "floating" with a 100 megabits to 95.
Settings should OpenWrt firmware for maximum performance, the removal from it of all unnecessary packages situaitsiyu not changed. Firmware version of the 15th gave tezhe results.
Then he flashed the very first and the oldest (combined previous) 2013 firmware that supports this version of the router - Attitude Adjustment 12.09 and it is even on default settings, flies without subsidence in single-threaded mode, return and reception. In addition, it takes up very little space in the flash memory of the router for some reason, and that obviously affects its performance. The old version of LUCI shell out of it, though less beautiful than the new but all the necessary functions have to tomuzhe if I am not mistaken LUCI Mona straight from roshivki upgrade to the new version, I just did not this zamorachivatsya, configured via SSH stopped uhttpd which is responsible for the web disabled-interface and its autostart.

Guys, I need help.
Deleted lan interface on the TP-Link TW741nd by OpenWRT, right now I can not go to the router. all the lamps are lit as it should.
returning control or can be reset to factory settings?



Rep: (283)
* Rasl2009,
reset to factory settings in OpenWRT is conducted as follows:

1. disable the router and WAN-wire
2. connect a patch cable to the LAN1
3. Includes Router
4. at the time of the activity SYS-LED, quickly click QSS
5. SYS-LED will begin to flash rapidly, indicating the transition to the FailSafe mode. If not, go back to step 1.

Open PuTTY. Host Name: 192.168.1.1, port 23, Protocol: Telnet. Click connect. Enter the current username / password.

At the command prompt, type the following: mtd -r erase rootfs_data

The command to reset to factory defaults

We do not touch anything, expect to complete all the operations and the appearance of phrases Rebooting ...

Hard Reset procedure completed

The router will reboot and now PuTTY window can be closed.

Copy-paste from the Runet, nepomnyu addresses but notes in the file is stored.
