[SOLVED] Bricked Fritz!BOX 7530: customized sysupgrade, missing critical packages?

Installing and Using OpenWrt
1

Hi all,

I've been trying out using the firmware selector customized build tool, and have seemingly discovered that this tool makes it very easy to accidentally brick a router (although I hope not!).

I was customizing the firmware image, made a mistake copying and pasting into the packages box and I believe I left myself without the following packages which are part of initial set in the box:

ppp-mod-pppoe procd procd-seccomp procd-ujail uboot-envtools uci uclient-fetch urandom-seed urngd wpad-basic-mbedtls

Not realising this at the time, I flashed the image to my Fritz!BOX 7530 and have seemingly bricked it.

So the question is, is this recoverable using failsafe mode? I've tried getting into failsafe, but so far no luck. I get at boot:

  1. All lights blink once
  2. Power LED blinks slowly 5 times
  3. Power on constantly

Tried pressing/holding all buttons during 2., but no luck.

I can probably get a Windows machine to use AVM recovery if worst comes to worst, but will be inconvenient.

Hope someone can help!

You have to get AVM recovery, procd, also known as init starts all multi-user processes.

Alright, thanks! I think I may have to make some recommendations for the tool to make this kind of error not so easy to make :frowning:

For the future, if failsafe is needed…

This is too early in the boot process.
The slow blinking in the beginning is during bootloader phase.
You have to wait for fast blinking. This is where openwrt actually starts booting and can react to button presses.

Fortunately, I think I've been able to source a Windows laptop to do this recovery job. Once bitten, twice shy!
