Realme C1 tested and logs posted, if there is problems must be during soldering/cutting.
You should carefully check everything.

Obviously that something is HW damaged. If You never managed to get connection with RIFF than it must be HW related.


If phones even not enumerate on USB (EDL or MTK BOOTROM) damage could be on power part.


It could be electro static discharge, for example.


Of course I can't tell because phone in your hands not mine.
