Installation ok but no boot after first power off

[m0m4x]

Hi all!
I'm trying to install latest version of OpenWrt on my Netgear WGT634U.
I have done the flash via CFE and a serial connection with the tftp method documented here:
https://openwrt.org/toh/netgear/wgt634u
Everything gone fine and i was able to boot new openwrt 18.06.2 like a charm.
I've done a basic setup in the new luci console via web and configured my home wifi network. (btw congratulations to everybody, this is a great project - you have done a lot of progress since my old installation v.8.09 kamikaze)
Then i accidentaly cutoff the power to my router and it didn't start anymore..
I re-attach serial cable and this is what i found:

CFE version 1.0.34 for BCM95365R (32bit,SP,LE)

This is the complete log of what i've done via serial connection:

https://pastebin.com/VkGu0Tcf

• flashing the new firmware (from line 66 to 91)
• boot and use the new shiny openwrt (from line 94 to 388)
• lost of power (argh) (line 388)
• new boot after power off (from line 390 to 413) (another try follows...)

Now, how can i boot the newly flashed firmware?
What i've missed?

Thank you all!

Nevermind...
I solved the problem issuing these commands:

setenv -p STARTUP "ifconfig eth0 -addr=192.168.1.1 -mask=255.255.255.0; boot -elf flash0.os:"
setenv -p et0phyaddr 254
setenv -p et0mdcport 0
setenv -p configvlan 0x1
setenv -p NET_DEVICE eth0
setenv -p NET_IPADDR 192.168.1.1
setenv -p NET_NETMASK 255.255.255.0
setenv -p kernel_args "console=ttyS1,115200 root=/dev/ram0 init=/linuxrc rw syst_size=8M"
setenv -p et0macaddr 00-00-00-MY-MA-C1
setenv -p et0macaddr 00-00-00-MY-MA-C2
printenv
reboot

...replacing mac address with those specified on my router.
