hello there,
the question is why did you move the board to a different housing. Second question, what did you measure and where. The motherboard of model 11 onwards is very different (as you know) from its predecessors. Not only because of the floor, but the entire connection logic has been changed. This requires a change in the diagnostic mode and especially in the way the fault is tracked.
The most common fault that causes problems with the radio system is a broken connection with the interposer. Start with this. The hint will be that after performing a system reset you are like blind and deaf on a busy streetway. This is obviously a metaphor, but it reflects the full situation in your motherboard. Remember that network service problems can originate from any part of the radio system and general power supply.
I am currently finishing a youtube video about the baseband issue on the model 11. It will be ready in a few days. Sit back and enjoy the movie. You're sure to learn a lot, as well as the Model 11 Temperature Control material. Coming soon, there will be an entire season dedicated exclusively to the Model iPhone 11. Every type of fault and repair methods. Completely free. I hope to finish before the end of the year.

I am always getting ERROR: device didn't accept BasebandData on 3utools restore. Forgot to mention that too

First of all thank you for your quick reply. I have changed the logic board because it was not turning on and found out that Lots of pads were cut off from the ways. So instead of making a way for all them changed the housing. I will check for the radio system but new on 11 so where can I look at directly?
By the way I have checked the caps resistors around baseband and bb pmu and also pads on diode mode. Everything was perfect. So I was just going to start to measure the top layer but got your reply.
Will check the radio too if you can light me up that where I can start with.
Thank you
Emre

the readiness of components can be read from various places. First determine what is missing. In contrast, the error "device did not accept baseband data" at the moment means nothing and has to do with the 3uT interpreter problem.
On pin 243 next to PA_HB_K on line 50_XCVR_RX6_MB_UHB_PRX diode mode has to be 350-390 but I get short on there. Changed third chip but still the same problem. Do you thing it may cause it? Because all the other values seems normal

I really dont know where else I need to check except that pin everything seems okay. And I have tried 3 different chips for there all same. I didnt understand. I remove the chip then it gives OL and no cut on the line there. But when I put the chip then it goes to short. The diode value must be aroudn 350 - 390 on pad 243 on PA_HB_K on line 50_XCVR_RX6_MB_UHB_PRX but it reads 0.01 after I put the chip. All the chips are broken and does this effect device cant get imei? Or should it be something else?

UPDATE: After I restore, I just found on 3utools there is no information for wifi serial number, wifi module and also the device restarts. And this is the log I got from the device:

这个答案有帮助吗？
Try reprogramming the NAND with the correct sys config info.
Do you think thats the only problem so what am I going to do then? reprogramme the nand with a basic sys config info then restore it again? how will it work? Can you explain a bit please
