Iphone SE logic board help needed

[tuscani]

Hi Specialists.

i have an iphone SE that has water damage.
The iphone goes on shows a white screen with apple logo for a few seconds goes of and keeps looping like this. it only works when connected to wall outlet or USB connection to my macbook.

i allready replaced the battery. screen and doc connector. but the issue remains.
i can put my phone into the recovery mode but when it has finished downloading the latest ios and lets the iphone reboot it starts again with rebooting and itunes will not continue installing.

i allready desolderd the shields form the logic board but cant see any corrosion on it als the the 4 chips above the battery connector look fine.

so i guess there is something broken on the logic board that connect towards my battery.
can anyone tell me if can bypass or any tips i can do?

Thnx!

i just need it to boot up once to get my pictures off it then i can trash it

Water damage is unpredictable. Something on the logic board could have been shorted out and would not necessarily show any corrosion. Water damaged iPhones are generally best replaced instead of wasting money trying to repair them.
