Devolo 1750e bricked after openwrt Installation

profi · October 11, 2023, 8:47am

Hi guys, I bought a used devolo1750e.
Was working well with default firmware.
Then I used the following command in SSH shell 
With Winscp I copied the latest firmware to the /tmp/openwrt-22.03.5-ath79-generic-devolo_dvl1750e-squashfs-sysupgrade.bin
sysupgrade -n -F /tmp/openwrt-22.03.5-ath79-generic-devolo_dvl1750e-squashfs-sysupgrade.bin

The output og sysupgrade shows somelink like --force ... will firmware write to stdin [w] ????
The bootet the device because nothing happens

Now the device is in boot loop ... 10sek .. starts with blue (I can see a link on switch) and thats all then red led and boots again. (loop)

OK, then tried to connect the external RJ45 Serial Port, but no output on that port.

Then I read in this forum that the external serial port does not work.

OK, I opened the devolo 1750 e and noticed this board.

Tried to used the internal 4 ports of the serial connector and only used the ports RX and TX.

Tried then with putty on serial port and nothing to see ?

Would be great if anyone can help further or do I have produced waste ?

need to connect the GND pin too.

profi · October 11, 2023, 9:11am

Ground is connected too. But still no output on console ?

frollic · October 11, 2023, 9:17am

swap Tx and Rx.
if still no go, disconnect the wires, short Rx and Tx..
you should be able to see your own writing in your terminal app.

profi · October 11, 2023, 10:10am

OK , I changed the RX and TX and now I am ble to see garbage on the console .

Did I need to chnage something on the console ?

Putty uses standard serial with 9600 Baud.

frollic · October 11, 2023, 10:16am

https://openwrt.org/toh/devolo/wifi_pro_1750e#serial, from where you took the photo, says it's supposed to be 115200.
it's actually written right under the photo

profi · October 11, 2023, 11:10am

Hm, have configured it in Putty.

Never had such experience with that.

Will try with short on RX and TX.

frollic · October 11, 2023, 11:12am

and those are incorrect .

why ?
you clearly receive "stuff", it's the speed that's wrong ...

profi · October 11, 2023, 11:17am

OK, it seems you have mor technical know how with the serial connection.

When I short RX/TX I get a clean screen.
Cannot Input or output anything.

What do you think, my serial Cable is an old cable from USB to Serial with the profilic driver.
Kown probs whith the old driver and cable from china.

How can I dignose that the cable is working and the speed is right ?

frollic · October 11, 2023, 11:22am

this should work
I assume the GND wire was disconnected from the Devolo too?

that would have been the test you just did.

serial output's readable.

profi · October 11, 2023, 12:24pm

Settings

output on console

Have tried with loop on RX and TX and GND connected PIN5 to the GND of the male DB9.
Cannot put any character in console.

Have tried with 9600 and 115200 Baud.

Looks like cabel is broken .. should I saerch for another cable ?

frollic · October 11, 2023, 12:43pm

the Prolific device you have, it's not for old school RS232 by any chance, instead of 3.3v ?

WarHawk8080 · October 11, 2023, 1:31pm

he said it was using the USB to Serial with the profilic driver adapter...let's hope the pins on the UART are 5v compliant...if not...oof

change Speed from 9600 to something faster...you can change that box...change from 9600 to 115200...otherwise you will get nothing but garbage

frollic · October 11, 2023, 1:32pm

I got one of two of those too, 9 pin RS232, hence the question.

profi · October 11, 2023, 3:56pm


Yeeeeaaaaah I managed to get connected .

This is my setup

![image|284x499](upload://uIILiX0S1BSLUcln7SlBhLi7v32.jpeg)

OK, now I am able to see fine characters ins the putty console

Can someone tell me, what I have to do to get a working openwrt box again ?

profi · October 11, 2023, 3:58pm

Sorry the pictures were in the text format

profi · October 11, 2023, 4:01pm

And I use this Adapter .. is from china profilic 2303HX with driver from 2013 (works on Win10 and Win11)

frollic · October 11, 2023, 5:58pm

Try option 2, and use the stock image from the manufacturer, of you can find one.

profi · October 11, 2023, 6:32pm

OK, I am able to use the firmware from delos.
firmware-delos-WiFi-pro-1750e-MT2785-v4.0.1_2017-10-20.bin

How to update when using

Please choose the operation:
1: Load system code to SDRAM via TFTP.
3: Boot system code via Flash (default).
4: Entr boot command line interface.

And I am wondering, cause a have another devolo1750e which I could install with openwrt Image .
But I do not know, which Images I used.

Ist there a bug in newer releases or what happend there. perhaps someone knows about a problem with newer firmware releases ?

On other devolo 1750e I get this in SSH screen

frollic · October 11, 2023, 7:48pm

As I said, in my last post ?

So it worked ?
