[EDIT]
Is this the wrong section ? If so, sorry !
[/EDIT]

Hello dear community,

once again some dau who bricked his TP Link WR703N.
1. I flashed the correct factory.bin and all went fine.
2. I saw the JFFS2 image and had read somewhere that for extroot you need JFFS2. For now I know this not necessary, is it ?

So I flashed the JFFS2 image and couldn't connect anymore.
I went into failsafe mode (reset button -> rapid blink).
Did firstboot = "had already been run" or something like that

I tried
mtd -r erase rootfs_data
but there came an error msg
so I tried
"mtd -r erase rootfs"
As I know now...this was just not that clever ....
Nevertheless I rebooted with
"reboot -f" and got stuck. No connection. No failsafe anymore.

Then I soldered as http://forums.openpilot.org/blog/52/ent … fi-router/ describes. The solder looks very good imho.

Connected the PL2303 cable in putty and powered on the router. Waited for "Autoboot in ...." but this never showed.
Instead I got this armageddon like log:

Is this just bad solder (I hope) or do I have sent this neat little router into nirvana?

Is this fixable ? Or trashable ?

I have done this already.

Although the cryptic symbols change with every boot.

Are you sure you have a good ground? The usb and ethernet shielding is not connected to signal ground.

this is...I ....you are my hero !
Ground was cold solder joint. Removed the exessive flux and pined it down.
Booting nicely !!

I am a bit rushing right now.
The gnd on the bottom of the PCB should work ?

any ground will be fine.
You got a nice ground solder point, look at the pic:

Al the purple zone is ground, you can scratch and solder anywhere or use the big ground point at the left.

I took one of the bare copper plates on the back but the big point on the left looks better to solder.

Thank you.
