SV04 does not boot anymore

5 weeks old printer does not boot anymore after power on. Does show starting screen without any further progress on system booting . Fans are on, BL touch moves twice but afterwards no more actions (waited 10 min) . Tried to switch on/off several times without any change of issue. Tried to reflash firmware but firmware.bin file stays unchanged (no change to firmware.cur) so it not even reads the SD card.
Nay suggestions or do I have to return the printer under warranty to Sovol ?
Thanks

I have the same problem. Is there any solution?

Try an other SD-card formatted properly (FAT32, 4096 Bytes, max. 8 GByte).
