ROM image for WAVLINK WL-WN578A2 / Aldi WLR-755 AC

Hello there,

I have a WiFi repeater with broken reset button and I didn't manage to hook it up to a new Wi-Fi. It is this model:

I'd like to directly go to OpenWrt but I need an image of the Flash-EEPROM, a 25Q64B from Giga Devices. Yes, I made a backup of the flash but I cannot modify it to get the repeater up and running in default config again.

Does anyone has this device and a programmer (like CH341A) and could provide a 8 MiB image of this flash ROM for me? An image with stock and default settings or even with OpenWrt would be great.

Thank you in advance
