today we have a mail and repair from the phone repair guru ever since the iphone x there has been a sandwich design where there are two boards connected together the top board has the cpu and is essentially the brain of the phone while the bottom board has everything to do with wi-fi bluetooth and cellular it only makes sense that if the top board cannot communicate with the bottom board we will lose access to these important functions we must repair torn pads and then replace the bottom board all together now we can inspect the damage closely under the microscope as expected there are multiple missing pads and install new pads using hot air now we can use uv mask to secure them in place we will remove the key components from the damaged bottom board this is in preparation to install them onto the replacement we need to take the baseband cpu baseband eprom wifi and xcvr intermediate frequency ic these four components must be transferred to the new bottom board as they are paired with the cpu if we just swap the bottom board without moving them it would not work the scary part of this repair moving the baseband eeprom ic it is incredibly small and if we lose it we are it cannot be replaced and it is paired with the baseband cpu so without it the phone could never have cellular functions we are now ready to solder the top and bottom board back together now we are able to place the top board onto the bottom board and let the heating platform do the rest after a brief moment the top and bottom board perfectly solder themselves together we can see that wi-fi bluetooth and cellular functions are all working perfectly following the repairs we will get the logic board packaged up and sent to the phone repair guru so he can complete the repair so we went from this to this i already installed the logic board so we're all good on that the phone is good to go but holy so of course we're gonna have these important messages important display message important battery message important camera message in the future maybe apple will remove these given some new news that they released but one can only hope i just want to say a special thank you to john zoid for sending this over this made for some interesting content and thank you for marnix for doing the job that i couldn't i'm still learning how to micro solder so this job was way above my skill level but yeah thank you guys so much for watching i really appreciate it don't forget to like subscribe and i'll see you guys in the next one
