Hi all, can you please someone help me with rescue my Synology DS218? During update from 6.2 to 7.0 there was power outage, after that my Synology does not start. I am able to connect the serial line, here is what i see after power on:

HerdekDedek,

I don't have the Realtek SoC Synology, so not familiar with its FW.

Base on this error:
------------can't find tmp/factory/000BootParam.h
[ENV] read_env from factory failed
[ENV] Using default environment variables

All I can recommend is that, perhaps you can find a bootlog with envs listing on a good DS218 box and see if they are the same as one you've listed above.
Realtek> printenv

Usually the u-boot internal environment variables are not what the box u-boot expects to see. Most implementations of u-boot use a default envs image that has necessary settings to boot the box.

My DS218 has damaged SPI Flash memory (MX25L6433F) and can't be used. I have replaced it with a brand new but downloaded dump is unfortunatelly partialy damaged too. I'm trying to restore u-boot but without luck.

=========================================

I have access to d/g/r> shell and DS respond to Kylin USB MP Tool (Realtek) on rear USB3.0 port. I think we need dump from working machine, replace MAC address + S/N (calculate checksum) and upload it... Another two cases with non working DS (another models but with same RTD1296 as SoC) that I found on the internet was repaired by the same way. Attempts to restore bootloader / kernel failed.
