hello xda. i need your help. im desperate. i dont know what else to do with my moto g here's what happened:

first of all, i dropped my moto g into the water.
right after i got it out, it startet bootlooping. then it turned off by itself after almost an hour had passed.

i put it in a bag full of rice for the rest of the night and almost the whole following day. then i plugged it into the wall charger, and it wouldnt charge at all. the only sign of life was the blinking led.
so i took it to Movistar-Peru for repair, and told me the obvious: water damage was not covered in the warranty, then my phone was returned to me.

so i decided to tear it down by myself.

everything was looking fine. the water indicators were red, but everything was clean except for the battery socket: there was mineral condensation around it. i wiped it out, cleaned it away and then the phone would actually charge the battery icon displayed normally.
so i let it charge for 3 hours and after it was completely charged i turned it on. just to run into a black screen after the bootnimation.

good news is it actually can boot into fastboot mode and can access recovery menu.


i did some research here, and seemed like my phone needed a full stock flash (thatīs what i thought). i decided to unlock the bootloader, using motorola unique code. (i thought it may be needed for flashing, but it seems it is not necessary)

in recovery, my sdcard folders display normally, i can wipe data/factory reset it normally, BUT when i try to erase cache partition, the phone reboots.

so i started flashing my device through fastboot. i should mention that before i dropped it into the water, i had installed 4.4.2 ota update. but whenever i tried to flash a 4.4.2 rom, i got hab check failed for sysyem, for recovery and sometimes for boot.
now, i've tried several official motorola signed jelly bean roms (nextel br, movistar sp, claro ar, etc etc) including original Movistar Pe jb rom (which ive already flashed uncountable times) with no errors on flashing, but neither of them got me passed the black screen after bootanimation. (the phone is not off, cause the backlight remains on). the only way of getting out of it is rebooting into fastboot mode again (volume- and power).

i've also tried relocking the bootloader, and the process gives me no errors (the word "locked" displays by the end, though the phone then reboots into the "warning bl unlcked" screen) , but regardless of that and the relocking process turning out okay, status code 3 is displayed in menu, meaning the bl wasnt really relocked..?)


in short:

-dropped into water, started bootloop, then it turned itself off.
-next day it would display black screen after bootnimation, no matter what i did.
-if i choose wipe cache partition, the phone reboots.
-i've flashed it "sucsessfully" several times, still runs into a black screen after bootnimation.
-i've unlocked the boootloader
-if i try to reclock: process turns out okay("locked" word by the end), but status code remains being 3.
-i dont care about backups, i had nothing important in my phone (gdrive ftw)

my concearns are:

-possible hardware unrepairable damage
-bootloader got corrupted
-mineral condensation is still there deep inside the components
-maybe gpu? emmc corrupted? semi brick? idk..

my questions are:

-what can i do from now?
-i've read that a new bootloader can be flashed into the phone. risk of bricking my phone?
-if the bootloader is the problem, flashing a new one would solve it?
-in general, what am i doing wrong in all of this? has my phone any chance of functioning normally, at all?

please help me , i miss my phone, i got it for christmas, it is my first smartphone and i woudl like to bring it back to life if possible. thank you for reading.
