I have encountered similar problems before. I used RecoveryTool Fix Recovery to solve the problem. It may help you.

First, please remove the upper and lower logic boards and put them on the PCB holder to restore. You can re-solder the mainboard if it ok. If not, please check the baseband CPU and baseband power.
