Apple MacBook Air "Core i7" efi request

[crazeej]

hello guys, got this Apple MacBook Air "Core i7" 2.2 13" (Early 2015)

slightly liquid damaged. there was a rework before me. smc no edgebonding and the efi ic was not perfect in place.

anyway replaced some resistors and caps what looked nasty. around smc and u7501 , u6101 r5177 smc tms.

the main issue is here he takes forever to boot!

after a pram reset at first boot up he boot little bit slower but he boots.

after pressing the power button he needs 10-15 seconds until he chimes!

replaced clear me from rossmann forum and changed fsys data line, after that he wont boot at all.

thank you for your help and answers

Is this the original dump? It just needed the ME cleaned properly, follow win-raid guide.
