I replaced my RAM with a hy5du121622DTP-D43 chip. The original was 32 MB from Zentel.
It was made by a professional with hot air gun in a factory line...
So it should be attached correctly.
Unfortunately I just see the power LED staying on and second one. No reaction...
Before I successfully upgraded the flash from 4 MB to 16 MB and also load the new boot loader from Pepe2k into my TPlink RE730v2.
Anyone knows how to proceed now?
