OP5 : black screen when lineage logo display + white led

[tifriis]

Hi ! my Oneplus 5 has slightly taken rainwater in my pocket. The phone wouldn't start up again.
I changed the battery. The phone reboots, the screen displays "1+ Powered by Android", then the screen starts to display lineage Logo and turns black and a white LED lights up.
I can't access the recovery mode by pressing power button + volume down.
Would you have an idea that would allow me to fix it? (I wanted to unbrick the phone but I can't enter to recovery ...)
thank you for your help

Use an EDL flasher (commonly known as unbrick tool). You can find it here on XDA

Thanks for your answer. I wanted to follow this guide (https://forum.xda-developers.com/oneplus-5/how-to/guide-unbrick-guide-hard-bricked-t3761706) but MSM Download Tool can't see my OnePlus (I followed the instructions but my phone doesn't appear under COMs and Ports).

For your information, I can get into the fastboot. With linux, the phone is well recognized in fastboot (it is also recognized with the tool TOOL_ALL_IN_ONE_2.0.1.3).

I tried this :
Sending 'recovery' (33689 KB)                      OKAY [  1.320s]
Writing 'recovery'                                 OKAY [  0.317s]
Finished. Total time: 1.721s
Sending 'boot.img' (33689 KB)                      OKAY [  1.289s]
Booting                                            FAILED (remote: 'Failed to load/authenticate boot image: 00000050')
fastboot: error: Command failed

You have to install drivers in special mode aka non signed driver install allowed mode in windows 10.
It's num 7 in the list of advance system startup.

For some reason i didn't had to do anything as my laptop already had everything somehow, i just open tool and flashed to 7.1 to test my phone. Now back to 10.

Only think I did before was installed htc 10 drivers to unlock and have custom rom on it.

Thanks but I did it (I followed this link : https://www.howtogeek.com/167723/ho...8.1-so-that-you-can-install-unsigned-drivers/ and I run "bcdedit /set testsigning on" then I restarted).
Maybe I have to uninstall some drivers before because my phone doesn't appear in the category " Ports (COM & LPT) ?

Here my screen after booting : https://cncloud.zaclys.com/index.php/s/bqMF3cDzMScjzgd

Thanks for your help

Hi ! I think I managed to install the driver (I had to remove old drivers).
Now MsmDownloadTool gives me this state :

Index : 1
Com : COM3
Status of Connection : Connected
SN :
Status of Communication : Param preprocessing

I'm stuck in "Param preprocessing". Phone have green LED. Any ideas ?

Thanks to help me to save my phone

For infomation, I succeed to use MSM Download Too. I was sotck in "Param preprocessing" because my battery was too low.
However, when my OP5 reboot, it displays the 1+ logo then get stuck with the red point and white circle, then reboot.

Any ideas ?

This is probably an hardware fault
