@PCGH_Torsten Unfortunately, yadi.sk reference is "official" download link. =D It safe to use, just result of execute file conversions. I will try to minimize it in future builds. If you beware of viruses, CoffeeTime can be used under VirtualMachine.
@nch2312 If no reaction to power button - check your shorted pins, seems to hardware issue. Bootloop or permanent shutdowns are usually related with incorrect ME flashing.
ASRock has locked ME region at default, so you need a way to around it. Software tools are usefull only if you will switch your board to service mode. The easiest way - find SPI programmer.
Edit: Changing SKU is required for 6+ cores cpus. Changing SKU also changes some data in ME region. You need to reflash ME region anyway. ME version in uploaded bios is 11.7.0.1229 - last compatible with CFL mod.
@nch2312 Describe board behavior at power on. What flashing method you use?
Correct if i wrong. I geuss, that you used bios shared by NickShin for your OCF. This version contains internal changes not similar with known CFL mod, so can be easily flashed with Instant Flash. Common CFL mod from community requires reflash ME region, blocked by ASRock. So you need use SPI programmer for it.
@chaehwasu Seems to all necessary mods are inside. You need to transfer MAC-address and other personal data using FD44Editor to complete mod. And I would recommend make pinwork as CoffeeTime suggested, not 2 pins only.
@Bluesmoke At the moment the only way to use more than 4 physical cores on MSI boards is swapping BIOS region from z370 donor board with ME downgrading. The problem is find compatible donor with similar VRM scheme.
