[Q] Nexus 5 exposed to water

Hello Guys
A while ago i received my N5 and i really enjoyed it! 2 days, i drop the thing in the toilet. :crying:
Okay so my insurance wont cover it and the phone has dryed in Rice and i followed all the advices that were online.
Tho i couldnt remove the batteri and i know this is a crucial point since the current+water will destroy the circuits.
Now my phone either wont start, or sometimes it will try to boot showing the google logo and then crashing (it cant enter the OS).
Is it worth trying to repair the thing? I dont think it will be a problem for me to change a circuit board og replace another part, but since i dont have any experience with phones i dont know what part i should start with.
The phone costs 580 dollars here in Denmark where i live.
Is it worth it ?
Regards Jesper

You can open it up, get some rubbing alcohol and submerge the board into the rubbing alcohol. Use a soft tooth brush and scrub the board. Usually the board gets corrosion/dirt from the water. Once thoroughly clean put a blow dryer to it (use medium to no heat. DO NOT PUT THE BATTERY IN THE ALCOHOL. ONLY THE BOARD!
I've tried this before and it worked like a charm when my Galaxy Nexus had water damage.

As soon as you dropped it in water you should have turned it off and left it off for days and possibly even took a hairdryer to it or let it sit in front of the heat vent.

Number one mistake is trying to turn it on. If anybody else drops the nexus in water. Because it has no removable battery cover. Rice won't do the trick. It would take way too long and the water would have already rusted the metal components and trashed all the pop connectors. If you drop the phone is water. Quickly take the entire phone apart. Than put all the pieces in rice. That will allow the rice to actually absorb the left over water. YouTube "nexus 5 tear down". Its always a good thing to know how to do this.

I just finished assembling the Nexus again and im a very happy man!
After disasembling the phone i found that the top board was very teared by the water and it was clear how some of the sockets had poor or no connection.
I used pure alchol (Dunno what its called in english) and a small toothbrush to clean the board. I dryed the board with a hair dryer on cold setting to avoid over heating the CPU parts. Now the phone works! and it doesnt look like it has any pearment faults or flaws. Even the display is normal and all my previous settings and the OS was intact. Thanks for the help everybody! and yes the best thing to do is remove the powersource and dry the boards individually if exposed to water
Best regards Jesper

Hey guys. I followed the instructions and have gotten my phone to power. Problem is when it goes from the power up screen that say "Google" to the colored balls, the balls freeze and it goes back to "Google" and freezing there. Any ideas on what I can do to get it to boot?
I just need it to boot long enough to retrieve my pictures and this hot chick's number I got right before the phone was dropped in the pool. Thanks.
edit: When I hold Volume Down/Power, I can get it to the bootloader. Anything I can do from here to salvage my stuff? I'm not familiar with bootloader options. Plugged into my computer, I can hear my PC make the noise as though it's connected which typically then leads to the phone's drive being accessible on the computer however it then immediately makes the noise of the phone being disconnected.

I believe I am having the same problem as you. I briefly dropped it into a creek for no more than a few seconds. That was enough to make the display unresponsive to touch. I was able to power down and quickly did so.
Unfortunately I wasn't near any rice immediately (motorcycle) so I put the phone in my mesh jacket in 100F weather and hoped for the best. I left it off at this point. When I got home I turned it back on (stupid I know) and the N5 didn't boot, only stopped at "Google" boot. I powered down the phone and rebooted, this time it worked. A quick checkup showed the external speaker didn't work for Play music, but did work for T-mobile visual voicemail. Also, the earpiece didn't work when I attempted to make calls.
At this point I realize I probably screwed up the phone big time. Once I realized not all components were working I put the phone in a ziplock bag with brown rice new from the store. I guess I'll let it sit for 48 hours and then attempt again. If it doesn't work, I'll attempt taking the phone apart and cleaning each part. And I'm really only going to attempt that because this phone isn't even paid off!!
These phones need to be made tougher! I am losing hope that there's any chance of my phone surviving at this point.

Nexus 5 Water damaged
Hi guyz,
I need some help, lately my nexus 5 was been water damaged. I immediately follow OuncE718 suggestion but I still experiencing problem. When I press on the phone I can feel the vibration but Google-boot logo will not display and it will only display a white-dim light in the bottom part of the screen. I tried to connect it in a Windows computer it will be recognised as a Nexus 5 phone. Does it mean I had to replace my LCD.?

Who knows what damage did the water do? If the corrosion sets in, your device will be hosed for sure.
It's really a fools errand to fix water damaged phones as no one can be sure the extent of the damage.
If you take it to a service centre, they'll most probably replace the lcd + mobo which will cost a bomb.

If you buy a new LCD, how will you know the Motherboard still works? Then what if you have to buy new motherboard?
Cut your losses. Replace the whole phone. Then get insurance

This ^
Spending money on a water damaged device is usually money wasted. Cause there's usually more things wrecked you find out along the way.
Save the money to go towards a new device.

I had the same problem, I used all the methods that I've read with no solution, my last hope is that the battery got damaged, is there a chance that maybe the battery is the problem? I can get a replacement for 20 dollars, but what do you think? thanks

[Q] Nexus 5 boot loop after it fell in water

Okay, so 2 weeks ago I dropped my N5 in a bucket of water. I took it out after 2 seconds and just tapped the power button to check if it was still on (so I could turn it off). It wasn't.
I got some dry rice, and covered the phone with it in a packet. I also ordered silica gel packets online.
3 days later, I tried turning it on, but it didn't, so I put the phone in a bag with silica packets inside another bag with rice and left it for a week.
I tried turning it on, but no luck.
So I kept it for another week in the same way. Today, I tried charging it and the screen came on. It shows the charging animation for a few seconds before it freezes and tries to boot.
It tries to boot, but it gets stuck either at the google logo or the animation with the colored orbs, and after a couple of seconds, loops back to the google logo.
It goes into fastboot mode and is stable there, but won't boot or go into recovery.
Any suggestions? I was hoping I could fix it myself or at least recover my data before giving it to the service center.

Let's skip to the end.... You're not fixing this. You're not recovering any data. I hope this saves you some time.

Can it be fixed at all? At the LG Service Center maybe?

No unfortunately not..water is both very corrosive and very conductive. When a device is powered on, water conducts electricity between components that shouldn't connect and burns them out and shorts them. Also the longer it is wet, the more corrosion that occurs.
People who manage to dry it out immediately over a 3 day period who end up with a working device are very lucky. If it doesn't work after this, its never going to work. Service centres won't touch water damaged devices. The other components can't be guaranteed. Some people manage to clean up the erosion with alcohols but even this is a long shot at this point.

Emmc is fried.. God knows what other damages the water has done.. It's best you go with the insurance route (if you have one) or get a new phone.

Dropped phone in water. now its stuck in bootloop.

so i went swimming with my phone for about 2 minutes yesterday before realising i had it on me. let it dry in the sun then rice bag over night. now this morning i let it charge and it booted up fine. but it started restarting. and at some point got stuck in a bootloop. i can get to the "power + volume down button" but i can not get into my recovery, any ideas?

You shouldn't even try to power it on...now pray. And go as fast as you can to the closest repair center and tell them what happened. Phone has to be opened and cleaned/dryed properly. You can't do that by yourself, or it is difficult to do it even with the tutorials on how to break it apart. All components should be cleaned with isopropyl alcohol and blown dry. Turn it off immediately and go with it to a service center...really
Every second while the phone is charging/powered, increase the chances to end up with a hardware brick. And the repair costs will be higher than buying a new one

ah wow a reply from a fellow romanian, salut! also theres no point in repairing this phone, the pixels are getting burned, the battery lifes getting shorter, but i would not want to have to buy a new one. that being said, the phone did work for a bit, i wanted to understand why it started not working?

Because water is doing damage in time not instantly. The water, especially from pools or even worse sea/ocean, contain minerals, salts and chemicals that remain on the circuits after water has evaporated. They have a corrosive action on contacts and electronic components and posess a high risk of short-circuit that's not immediately observed, making a device totally unusable. The biggest initial risk is to fry a component due to a short-circuit, that's why is recommended to power off and take out the battery from such devices but that's not all. Unfortunately taking out the battery from the One S is not possible as with other phones so parts of the phone/board still remain powered even if you turn it off. Now as time passes by, water and it's components are doing a slow damage unless phone it's not properly cleaned inside. That's why I told you about isopropyl alcohol. Trust me, if your phone still works is a miracle and you still don't know if parts of it are not ireversibile damaged. Any time using it further like this will increase the chances to have it permanently bricked.

aha i see what you mean. i got a bit impatient, turned it off, and drowned it in isopropyl for about 15 mins. now im waiting for it to dry out again as i can see the isopropyl inside my camera. also another thing, ever sinc ethe bootloop, if i plug it in and its turned off, it will automatically turn on after like 10 seconds or so.

Oh no. I told you to go with it at a service center not to submerge it yourself in alcohol. That's not how it should be cleaned. It should be opened and components wiped with alcohol not drowned in it. And surely not when the battery is still connected.
Reboot to bootloader (if you still can) and you have there option to power off. It won't start up again. Leave it like this till you go to a service center, DON'T try to do something yourself again

Ok. Then search on youtube or here on XDA, was posted a video how to disassemble the One S. After you take it apart, disconnect the battery and wipe it with cotton balls and alcohol. Especially the contacts and circuit. Dont rub it hard, just clean it gentle... And don't drawn it again in alcohol. Let it dry completely after that. It might be that camera has been permanently damaged if you seen liquid IN it. Also the screen is very sensible if water or any other liquid gets between it's layers. And you should be very careful with every contact...and light up a candle for it will you, maybe it'll help
Such operation at a service center should cost you less than 100 RON, you should make some calls and ask

yeah ive seen it, and will definetly try it if i dont see it working after this dry off, only think im worried abut is not having the star headed screw driver for some of the screws, but i guess you can try to use other types of screwdrivers. also i am in canada but yeah it would be about 50$ which is 100 ron. thank you for all the advice and have a good night!

man, if i tell you, youre not gonna believe me, but after drowning it in iso and letting it dry in the sun, it works just fine now and the commands that i gave it from the boot menu , which were to erase data and factory reset did not work, i thought they did, but i guess it makes sense because as soon as i pressed them the bootloop would start again. also the initial time when i tried my phone this morning it seemed like it was charging a bit too fat (the percentage), which it doesnt seem to be doing now, and im glad, cause i think that means that whatever problem its had is gone, or so i hope lol.

Restore the phone to stock and send it to Sony, it may be a gamble if you have unlocked the bootloader before however. Make sure it doesn't die while restoring!

It doesnt really matter if it die or not its water damaged anyway.. They should replace or repair it

Depending on your repair center there could be charges

if it dies, in opinion, if under warranty, it would be good for you.

Lots of people have a waterdamaged Z3 after contact with water allthough it is advertised as a waterproof Phone ??
A friend of mine took it's Z3 to the pool to take some pictures in the water and killed the lcd after some pictures.
Not so waterproof after all.
In your case your motherboard got damaged, the motherboard probably gets so hot from the shortened components it shuts itself down. Is the back of the Phone really hot just before it powers off ?
Water itself doesn't kill your Phone, it is water in combination with courant.
The biggest fault most people make when there Phone had a contact with water is trying to power it back on to see if it is still working.
The Phone powers itself off to protect the motherboard from damage when it is short circuit by water.
By trying to power it back on immediatly after the waterdamage , you put courant on the shortened circuit and most likely burn out a component.
Best way to threat a Phone after waterdamage is to take it apart as far as possible and put the parts on a hot plate ( or other heat source) at about 55 degrees Celsius for half an hour.
Afterwards clean away the waterresidu with IPA and a toothbrush before re-assembling the Phone.

Galaxy S7 G930T Water Adventures

A couple days ago I dropped my phone in a lake. It was about 10 feet. It filled with water. I removed the sim card and got rid of water.
I left the phone in a bag of rice for a day and tried to turn it on. It keeps rebooting on the screen where it says SGS7 Powered by Android. I tried to get into recovery mode. When I do that it keeps trying to get there. The only thing I see is blue "RECOVERY BOOTING....". I got into the Download mode and flashed the phone with Odin with 4 file firmware. Nothing changed. Still seeing the same thing.
Is it a brick?

The S7 has an IP 68 raiting, meanging that (in theory) it can resist being up 30 min submerged in up to 1.5 meters (which is a bit less than 5 feet). You've probably damaged the hardware on the phone. It might be fixable by a techincal service (although the offcial one wil tell you the warranty has been voided).

Removing the SIM when it was wet might have been a mistake, as you just disabled the IP68 water resistance rating by creating a way for the water to get in
Possible 10ft was too much, but have seen tests that way surpassed the suggested limits and it was fine

Well, the thing is that I didn't remove the SIM right away. I dried the phone, it was fine. But in a minute it stopped reading the SIM. I gave it a couple minutes. Nothing. Then I restarted the phone, which brought me to the problem that I have now. It wouldn't start.
Then I realized that the water probably got into the phone. I removed the SIM and water started pouring from inside.

That sucks, IP68 rating should have prevented any water getting in, but as above, maybe 10ft was too deep and the pressure too much for the phone seal

I'm pretty sure that's what happened.
I'll take it to a repair shop and see what they can do. It's too soon for this phone to finish its serve...

They'll probably sell you a new motherboard / battery at best, and likely a new phone at worst
That's the problem with not being able to remove batteries in phones these days, if you get them wet you have no way of preventing a short circuit / damage
Generally if you can remove the battery fast, you minimise any damage
Also a big factor in phones not working again after getting wet is the impurities in the water that remain on the electronics even when dry, you need to use something like Isopropyl Alcohol to clean it off
And if the lake was salt water you have even more damage, back in the WWI days soldiers used Sea Water to defuse bombs as it would quickly cease up all the working parts inside the fuse/detonator section iirc

Wow, that's a good peace of the history right there I really liked it! Didn't know about those soldiers' methods.
Speaking of, no, the lake was a pure mountain water.
And I just want a repairman to take a look what he can do. I already bought exact same phone since I couldn't wait, really need this phone for work and other business. However, I'd like to fix it rather than having it as a peace of memory. So hopefully they'll be able to fix it under a $100 cost.

Good luck, hope it doesn't cost too much to repair
