Hello, I bought a new battery for my iPhone, but since I don't have a programmer, I wanted to put the old circuit board on the new battery and no matter what percentage of capacity it shows, i want the foreign battery message to disappear. However, after replacing the circuit board, the phone does not want to turn on, it constantly lights up that there is no battery, and once it happened, the Apple logo was flashing, but now it constantly shows that there is no battery, can you give me some advice?
Just to add, I was looking on the internet at an iPhone 11 battery change and they put 4.2 volts of current on the battery somehow to activate the BMS chip and I don't know if it's that or something else!

I forgot to say that it is probably not necessary, but it only works in the charger and shows that there is no battery
