MR3020 issue when installing PirateBox 1.0

Hi,

I've just bought a MR3020 to test the PirateBox 1.0 system.
But I've got a problem !

Here's what I did and the problem I encounter :
- I have plugged a 8Gb usb key with the install directory in it
- I browsed to 192.168.0.254(in 3G mode) and did a firmware update (the firmware is the good one : openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin)
- The router restarts but after waiting a couple of minutes, something seems to go wrong : the router reboot every 20 seconds.
- So I decided to unpower the router an look inside the content of my usb key. I've found that it was NTFS formatted. So I formatted it to FAT32 and plugged it again to the router.
- After powering it up and waiting a few minutes (15 minutes), the lights were stables and I decided to try the telnet, witout success because there was no route to host.
- So I decided to unplug the usb key and look inside it's content. The log show me that the key was too small (no space letf on the device).
- I'm currently trying with a 32Gb usb key, but it still the same : after rebooting and waiting a long time, I can't access to the router (192.168.1.1) using telnet. Windows tries to get an ip address but can't. Inside the install.log this is what I get : http://pastebin.com/FeNdj9wZ. What I see is that there is no space on the device... but I'm surely missing something...

The access point "PirateBox : Share freely" is shown and my android phone, but I can't access it : alway trying to get an IP address.

What should I do ?

Cordially

Jean
