Help Unbrinking WD EX2 Ultra (Debian)- Bricked after flashing new uInitrd and uImage (no replies)

Hi guys, long time ago i had installed debian on my WD EX2 Ultra (directly on the board, no USB) and it was working perfectly. I had opevpn server, trasmission, samba etc running on it :)

Today i found this instruction online to update the kernel from 4.15.x RC6 to 5.x.x...: and did it from my shell:

## Usage
# Update Kernel if you have access to shell
wget https://raw.githubusercontent.com/vzhilov/WDMC-Ex2-Ultra/master/uImage (--no-check-certificate in case of error?)
dd if=/dev/zero of=/dev/mtdblock1
dd if=uImage of=/dev/mtdblock1

# Update ramdisk if you have access to shell
wget https://raw.githubusercontent.com/vzhilov/WDMC-Ex2-Ultra/master/uInitrd
dd if=/dev/zero of=/dev/mtdblock2
dd if=uInitrd of=/dev/mtdblock2


I did as above and restarted my device, after restarting my device has now the main led blinking blue and no telnet or ssh access :(

Any way to recover it of is it briked for good?

Thank you all in advance
