You might post on the Cisco forum to see if someone can get you a copy of the original ubi0 partition.
There are other resources you might look in to...

Unfortunately, it's a hard lesson to learn.
hey . i am also facing same network issues. can you help me
if possible can you send me the file with working network connection
not exactly hard bricked as i can boot to lede from the tftp image on the uboot, i'm just missing a partition that i dont know what purpose it serves.. sealghost, do you think you can make me a copy of the board-config partition? i'm missing that partition because i accidentally deleted it, even though i have no idea what purpose it serves.
Likely the same for meraki...

thanks, i'll see if i can ever get to that point,
would you happen to know why i can't flash lede to it? the sysupgrade command seems to fail to create the rootfs partition, saying the partition make command can't have 0, its as if its using an incomplete or wrong command to do it.. :\
i can try to download the board config file but my network is not working. if you can explain me from where you removed the VLan and Bridge config details. i can connect to network and make copy of boardconfig file. Thank you
sure, so once you boot into the tftp image, you have the shell, then do
vi /etc/config/network
change lan from eth0.1 to eth0
change wan from eth0.2 to eth1
change wan6 from eth0.2 to eth1
then go to bottom and there is 3 seconds of switch0 stuff,
just delete all 3 switch/vlan sections, then save and exit vi,
after that type /etc/init.d/network restart
then you should be able to communicate through the network to the box
@alphaz18 thank you very much. network is working great. So please tell me how to download the board_config file. so that i can send you. i know it is in /dev/ubi0 -N board-config but when i tried to copy the file ,it isnt copying.
nice to hear! umm for copying the file.. i think you do "ubinfo /dev/ubi0 -N board-config" to determine which partition it is.. the partition id will be listed. then once you determine that, "dd if=/dev/ubi0_XX of=/tmp/board-config.img" where you replace XX with the partition id, so if partition id is 2 then do "dd if=/dev/ubi0_2 of=/tmp/board-config.img" then find a way to copy the newly created /tmp/board-config.img file somewhere so that you can post it? 
thanks!
Once again thank you
here is your board_config file
thanks! much appreciated! now if only we can figure out how to flash the permanent image to it.. without the thing failing..
clearly i'm not a programmer, :\ though i have a software engineering degree lol...
but i got it working, super duper hacky, but i dont want to spend the energy deciphering all the scripts, so for me there was a bunch of different things going on, first if i boot to initramfs then do that stupid trick to get lan working, then go to the http gui, and click sysupgrade and give it the tar file, it fails saying not a valid image, which is really stupid to begin with. so then i went into the serial console, wget the tar image to /tmp, then tried sysupgrade with -F and it still failed saying could not create ubi partition with size 0... i dont know what the hell is going on there. so i went into /lib/upgrade/nand.sh then scrolled way down to where it was doing ubimkvol -N rootfs then if you look a few lines above that theres a condition for the size, either "-m" or "-s blabla" i changed the blabla variable to 16MiB , so that it can successfully get through that portion of the sysupgrade script, then it failed to find the image because apparently it was looking for mx60/root in the tar file whereas in my image its mx60w/root so i downloaded 7zip, opened the tar file, renamed the folder from mx60w to mx60 then wget again to the box. then now this time ran the sysupgrade -F -n -v /tmp/lede-blabla.tar worked! then once done, plug in the network to port one of the switch side and not the wan anymore, and .. suprisingly everything seems working! i didn't try the wireless yet though. but shrugs. thats enough nonsense for a week for me.
so recap:
step 1. follow most of this guide https://github.com/riptidewave93/LEDE-MX60-MX60W Up until step 7.
step 2. network broken so do fix above, ie delete switch and rename interfaces without vlan from /etc/config/network for the time being when booted from initramfs image. then restart network /etc/init.d/network restart
step 3. if you are on mx60w like me, open the sysupgrade.tar file in 7-zip and rename the mx60w folder to mx60. exit.
step 4. copy the modified tar from above into /tmp of the device using a http or whatever method you can do.
step 5. go edit /lib/upgrade/nand.sh scroll down to where it creates ubimkvol -N rootfs $sizewhatever , a few lines above theres an if statement saying that variable is either -m or "-s $1" replace the $1 or wahtever is there with 16MiB (i just randomly chose this number) since its larger than the image so "-s 16MiB" save the file. exit.
step 6. go to /tmp and run sysupgrade -F -n -v lede-blabla.tar
should reboot in a few seconds. then you're done.
step 7 plug in network to lan1 port now everything should work 
hi. i have booted and upgraded all the firmware settings. but i can only see one interface eth0. what happened to other four interfaces. do you have any idea? and help me to activate other interfaces.. Thank you
so which steps did you do? were you able to do the sysupgrade successfully?
yes i was able do sys-upgrade properly using gui. it went well. but i can see only one interface eth0 not others. where you able to make your work? . if it is working do you see all the interfaces ?
which version of the image did you use? I used 17.01.4, when I tried the dev snapshot, the other ports wouldn't even light up. so I conclude that the dev snapshot for our box is just completely broken. if you only see eth0 and it upgraded properly, try a factory reset on the settings, it should set everything back to the vlan/switch stuff which is required for all the ports to work properly.

EDIT: That file appears to say "meraki_mx60 600-16010" ...mine reads "meraki_MX60W 600-16015."
guys, any1 can help me with this MX60?
I also deleted whole ubi partitions and one and only way I can reach mx60 is via tftp.
after that i cant flash tar file etc.
I need board-config of MX60 and lil help of some1 from this thread
can some1?
Sure...if you Private Message me...and provide the:
I'll recreate the board-config.img for you.
You might have an issue though, since you deleted board-config. This also means you may not have created the recovery partition. Start with fixing board-config, first.
