Hi at all, have this oled switch that don' t turn on. Have see with microscope that clk trace is missing, it was scratched too much. There is alternative point or have a method to fix it? Attach picture. Thanks in advance

If you have a hot air rework station you can sandwich a daughterboard between the motherboard and the emmc, it will give you acces to the dat0, clk, and cmd pad

But you need to still run the clk trace back to the cpu, hopefully there is some trace left to solder to. Im guessing that the via is gone/unsolderable?

Exactly, the problem is that the track between emmc and cpu is scratched to much.
I should recover the trace starting just below the cpu socket if there is any way. Thanks again
