please help me. i'm 100% sure that some one has cleaned before the board from corrosion. here you can see the areas cleaned and the amp drawn at boot https://drive.google.com/drive/folders/13sMBCH8L9jEkpUPyzv_70ymiAkHtqIQd?usp=drive_link i don't know where to start, please help!

i've not replaced C3430/1 since you told me to remove them!

can't be anything else?

bluetooth is working AP_RESET_L = 3.3V AP_CLKREQ_L = 0v AP_WAKE_L=3.2V

i remember: i've changed those Q3406 Q3470 Q3403 U3404

pp3v3_s3 mini and pp1v5_s0 present, but no wifi card. changed with another card. still the same. help!!!

changed u7700, now system boot but now wifi card :( i'm going crazyyyyyyyy!!! what should i check about the wifi card?

i'm going crazy because i'm not 100% sure like before that problem is related to wifi card. i've done dozens of tries (on/off) with and without the card: 90% of times it doesn't boot with card inserted. 10% it boot with card inserted 90% of times it boot without card, but 10% of time it...

edit

changed the mosfet too..still the same... i don't understand the connection between no boot and wifi card, because of the fact thah the wifi pin is an "Input" from the motherboard

u3404 is the same in those boards, so i've changed it...now i should chsnge q3403, but i don't know if it is compatible. please help
