Panic over! 
The next time you want to flash an image, just setup tftp and run "run update_openwrt" and "reset" since the variables are now saved.
Yes, it can be undone but by "bricking it" i mean OpenWrt will boot, but your ethernet ports won't work and you'll need to dabble with the serial again to fix it. The v2 image vs v1 has just a phy driver change

Hopefully DLM removes the cap on my IP profile soon as I have yet to test the throughput. I really wish we could disable this rubbish for situations like hardware testing!

All setup - unfortunately syncing about 7Mb lower than my Billion 8800NL.

How would I configure the ECI to act as a router as well as a modem?

Hopefully within time it might sort itself out

You can connect LAN2 and use it that way, though it requires you set a static IP. If you want DHCP re-enabled,
login via SSH and nano /etc/config/dhcp

Change

config dhcp 'lan'
   option interface 'lan'
   option ignore '1'

to something like

config dhcp 'lan'
   option 'interface'   'lan'
   option 'start'       '100'
   option 'limit'        '150'
   option 'leasetime'   '12h'
        option ra server
        option dhcpv6 server

and

/etc/init.d/dhcp restart

[GigabitEthernet]

Oh is there an adjustment period when you change the chipset? I've only ever used Broadcom so I've never had a chance to test it.

I had interleaving reduced to a depth of 1 on the upstream today so I've got a couple of Mb back but the ECI is still 2Mb slower than the Broadcom modems I've used

So the way you've described will allow me to plug a device into LAN2 and Internet will work via this port?

[jsamuel]

There is I believe, and the DSLAM might resync and realize the CPE has a different chipset but I don't know. Or it could be that you've switched the modems too quickly and the DSLAM has lowered it a tad, but will fix itself.

Sorry, lack of sleep 
The way I've set it up by default is LAN1 > Router WAN, LAN2 > Router LAN.

I assume the way you want it setup is
LAN1 > Router WAN
LAN2 > PC?

That configuration _should_ work out of the box too.

[GigabitEthernet]

Well actually I wanted both ports to go to a PC

[VDSL2User]

I think I have killed my ECI /r V 1.1 attempting to install OpenWRT
I had an old spare ECI which I had attached the UART header to some time ago.
Well i ran all the instructions up to and including the run update_openwrt but when this
got to the copy to flash part it just kept coming up with something about protected
At this stage I thought that if I had any issues I would be able to use UBoot and try again
so I went ahead and did the reset as I could think of no other way to get past the issue.
Now I can get UBoot but there is no images in the flash as I guess the erase command from the
update_openwrt has wiped them (just get bad magic number messages)
Problem is I don't appear to be able to get the VR9 switch to operate anymore, no lights when ping etc
and cable disconnected on the laptop. Tried alternate RJ45 cables but no joy.
Am I correct in thinking that UBoot does is not enough environment to actually use the VR9 switch ports native?
When I try a ping it says using VR9 Switch device and then a while later comes up with host is not alive
(no lights on the LAN port come on).
Oh well you win some and you lose some ..... it was only a cheap spare that I never use as I have 2 HG612's
and a Billion 8800NL for connection, just liked OpenWRT which I ran on the homehub 2 some years back with ADSL.

[GigabitEthernet]

When you turn on the ECI modem with the UART connected, what do you see?

Could you post the output?

[VDSL2User]

Well I found I had another ECI modem hiding away in the cupboard, this one a V 1.2
It also had a header from UART in place as I had looked at an unlock some time ago.
So off I went with all the instructions again (remembering to use the V2 test image this time)
and hey presto it has worked and I now have OpenWRT running.
Now the new setup has the modem on IP address 192.168.1.1 which clashes with my ASUS RT-AC87U router
I can see the WAN bridge and LAN settings page (when plugged into LAN 2 with a static of 192.168.1.100
on the laptop) but not sure how to best change this to say 192.168.2.1
I could change the ASUS to operate on the 192.168.2.x subnet I guess as an alternate option.
At present I have an additional interface on the ASUS eth0.1 which uses 192.168.2.253 and an IPTABLES
command to route all traffic for this subnet down the WAN link allowing me to access the router (HG612) via a single
cable running both PPPoE and LAN. The HG612 is on address 192.168.2.254 and has the PPPoE vlan unbound from
LAN port 1.
Can the ECI with OpenWRT be made to operate in the same way ?
I plan to try the ECI on the line tomorrow (I am on a Huawei cab with G.Inp enabled so can see if it is picked up ok)

Just spotted your reply AlecR while creating the above post .....

[GigabitEthernet]

So you can't type anything next to VR9 #?

[VDSL2User]

Yes I can type anything , above I tried a ping 192.168.1.100 (the laptop connected to LAN1 port)
but no port lights (amber or green) and a cable disconnected showing on laptop then router
gives not alive response after about 15-20 seconds.

[GigabitEthernet]

Then you should be able to follow the instructions to flash OpenWRT again and it should work perfectly

[VDSL2User]

I have tried a couple of times but with the LAN link down the TFTP never
connects and downloads the image, it just keeps displaying T T T T then
times out and repeats over and over.
I will have another go at it tomorrow but now I have a working V1.2 ECI I am
less bothered about the V1.1 broken one (I think something may have gone
on the electronics to the LAN ports that just happened to be at the same time I was
working on the device.

[GigabitEthernet]

I believe you might have flashed the V2 image on the V1 as previously jsamuel said the ethernet ports not working was a symptom of this

He also said it should be recoverable so I suspect he can provide assistance soon
