You are supposed to post a question in English.
I assume you managed to boot other similar router openwrt on this new revision of C50V6?

Devices that are stuck or have blinking LEDs, just upload one of these updates, tested MT7628AN.

In general you need to revert to version that was installed before OpenWRT to match bootolader with kernel.

Actually snapshot supports it:
