RT-AC56U Decompressing ... error 1

[Ivanych]

I've got a bricked router. UART gives on start:
Decompressing ... error 1.
CTR+C- does not do anything.
Any idea to alive device?

Thank you!

Welcome @Ivanych, you need to give some more information.

What firmware was installed on the RT-AC56U, what firmware were you trying to flash onto it? What method were you using to flash it?

The RT-AC56U is very hard to brick.

What have you tried since it 'bricked' to fix it?

 

[Ivanych]

It was no LED. Only power LED lights. All other worked.
What was installed I dont remember. I tried to install FW_RT_AC56U_300438251641.
Flashed from WEB Gui: Administration > Firmware Upgrade. Upgrade, reboot - nothing changed. Pause 10 min. Coold restart and brick. Tried press WPS, RESET and their combination with power ON.

Well, that certainly dampens the day.

Worse comes to worse, you can try the firmware restoration tool for this model; (pick your OS and look under utilities)

Try the following link for the information you need to flash your router.

RT-N66U not giving full gigabit download speed

I got a 1000 Mbps line since a couple of weeks and I use the Asus RT-N66U. But what strikes me is that the upload speed is constantly 940 Mbps while the download speed fluctuates between 800 and 840 Mbps. Does anyone have any idea if any setting needs to be changed to get the full 940 Mbps...

I cant get rescue mode via above link.

What can't you get about it?

I cant get rescue mode via above link.

I know what you mean. On first opening the link, the website only partially opens. Give it a few minutes. Depending on how slow Asus is today, you will eventually be asked to select the OS that you are using. Once selected, it will be the first download (Utilities).

I just tried it. Took about a minute for Asus to catch up.

Hold "RESET" + "Power on" dosnt make rescue mode. Router cant boot at all.
Boot log from UART connector:
Decompressing ... error 1

By power on, are you using the power button or plugging the DC power jack in the rear of the router as instructed in the instructions that @L&LD pointed you too?

[Ivanych]

I've used both variants. There is no RESCUE mOdE.
Is there any possibility to write firmware straight into flash via UART?

 

[L&LD]

Holding the Reset button, having the power switch to 'on', but the router not plugged into the power adaptor for at least a couple of minutes, and then plugging in the power plug into the router (still holding the Reset button) and then waiting for 10 seconds before letting the Reset button go will/should put the router into Rescue Mode.

You may need to keep doing this until your timing is right. Don't give up after two tries.

Router cant boot to rescue mode at all. I suppose flash has been broken. Does anybody have fulldump?
Thanks
