Sorry Christian, this is not the way crypto works.
Your suggested chain has a very low hashrate, while the majority of miners is hashing at a different fork. You can't simply define your fork as the right one, you have to bring the majority of miners to consensus. Change the code accordingly and hope the miners update to this.

As far as I can see, the fork with the highest hashrate is currently at block 212747

getblockhash 212747
0000000002e95e21c399d5d72b5d8ae9371bda10eb35a67f888ac17c7517a873

hope you can fix this mess.
