Face ID can not be activated after soldering i2C flex cable
Hello guys, I would like to get some help with a strange issue that I came across.
I have repaired an iPhone 11 and 11 Pro with FaceID issue. I will go through the process step by step. First I attached the original FaceID flex to the i2C programmer and read its values. After that I connected the new i2C and wrote the original flex values. Then I desoldered the chip from the flex, removed the mosfet and did the neccessary jumper. After that I soldered the chip to the new flex and attached it to the i2C programmer. The test showed pass, I also checked under camera and all 4 spots of the projector light up correctly. Being happy that I did a good job I assembled back everything and started the phone. Now I am greeted with a “FaceID can not be activated on this device” message. I was thinking maybe my flex is bad so I took a new i2C, copy and write the data, desolder the chip and resolder. Assembled back everything and the error still pops up. I thought okay lets solder the chip back to the original flex. Now the error is gone but ofcourse FaceID doesnt work. I have the same issue with an iPhone 11 and an iPhone 11 Pro. What do you think, what could be the issue? I did around 25 repairs before without any issues.
Esta é uma boa pergunta?

Everything works fine for me with the 4 points, but it says iic abnormal, I already received the iPhone xr with the flex changed, now I don't know what flex it is, but on my JC it gives me a chip error
