I received a used RUTX11 which doesn't work. Only the power LED turns on and the network activity LEDs are flashing when the device is powered and connected via LAN. It doesn't provide any Wifi network. Also I'm not able to get into the bootloader, neither when holding reset for 4s nor when holding it for 6s (there are different informations about the duration on the wiki pages). What else could I try? Is there a way to flash the firmware via JTAG or something like that?
This could really mean whatever!?
What firmware does it have installed to begin with?
RutOS (OpenWrt based Linux OS)

This is what the manufacturer say, this isn’t OpenWRT but OpenWRT based so if this is what is installed then you need to contact Teltonika support.
To be honest, it's a complete black box. I don't know what happened to the device. I received it as "provides no connection". The last owner also doesn't know what happened. I assume it's running the default firmware, but I also don't know that for sure.
I made some pictures of both boards. Beneath the USB port there is a pin header. I assume it could provide the serial port, but there's no pin description.
The “big” square surface mount chip up in the left corner on the second picture looks like it is covered with a powder that looks like charcoal.
That is thunderstorm destruction level 1. And usually how a microship looks like when it is cooked by lightning.
Thunderstorm destruction level 2, lightning evaporate the chip completely, sometimes the legs are left. Sometime the legs are gone and the chip is left. But something is always missing…
Thunderstorm destruction level 3 is when both the chip and the circuit board directly under the chip evaporates.
Thunderstorm destruction level 4 is when the house burn down.
The consistency of the material on that chip is more like rubber. Maybe some thermal paste, although it looks very strange if it was and it doesn't touch the housing at all. And it doesn't smell at all. I don't have the impression that it has burnt down.
Teltonika only supports devices which where directly purchased in their shop. As I didn't do that they won't support me.
Hi all,
I have just received from my family the same device with exactly the same issue.
However in my case I know that the firmware was not replaced "openwrt".
I assume it is something in regards to the power supply unit - however @myscha - can you please tell me if you solved your issue and if yes how ?
kind regards
Remove power, then press the reset button and hold it attach power, continue to hold the reset button for 15s, after that you should be able to connect to the embedded failsafe webif, which allows to to reflash the device.
Hi @KONG,
thank you for the fast answer and suggestion, however I ofc. tried it, but never receive an IP through any of the ETH-ports - even if I put a static 192.168.1.x ranged one (this device should have a 192.168.1.1 IP) I still cant ping it.

Unfortunately I wasn't able to solve the issue and returned the device to the seller. As I got it via ebay from a commercial shop it was no problem to return it. Meanwhile I have a working RUTX11 which was also on ebay. It was offered as 'defective' and without any accessory, but luckily it worked like a charm.
As Teltonika doesn't offer any support for devices from 3rd party suppliers I consider it very complicated to unbrick their devices. I wasn't able to establish any connection to the first device I had and therefore couldn't reflash the device. I followed their wiki and faq and tried all guides and howtos I found, but without any success. I didn't try to recover it via UART or JTAG, so maybe this could help. But I have no idea how to do that...
