Hello everyone,
In the past week, I have decided to sell off my Nexus 4, and I went on to buy a new cheap unlocked 40$ android phone and a used water damaged Xperia Z.
I had just got the Xperia Z a few hours ago, and the guy who I bought the Z from, said a bit of water leaked into the phone about 2 weeks ago, and ever since then the phone does not turn on.
So far I have pretty much disassembled the whole thing, and noticed that all three water indicator stickers at the ports have turned red.
But I seriously cant find any water, damage or corrosion on the phone's connectors, internal frame, battery connectors, anywhere.
I guess only a few drops has entered the phone and over time the water evaporated.
Now after drying the internal components in the sun, and using 70% isopropyl wipes (I looked everywhere for 99% isopeopyl Alcohol liquid, I cant find them everywhere) I wiped it over the phone's motherboard and then used a toothbrush to remove any dirt or corrosion building up in the board.
Now the thing is that the phone does not do anything when I plug in the charger.
But when I remove the battery, and plug in the charger, and press the power button, the phone's LED blinks red for about half a second, then vibrates once and then a blue LED light comes and stays on. However nothing comes up on the screen.
I tried the Power button and Vol.Up button, but it does not do anything.
The Z's battery seems fine, as I tried it out on my Xperia C and it works perfectly there.
And I tried the Xperia C's battery on the Z. Same thing no response from the phone
What should I do?
I guess look around or a 99% alcohol solution and properly wash the Z's motherboard?
Or is this some sort of a software issue?
Any help will be appreciated.
Thanks!

To me it rather looks like the seller modified the software and hard bricked the device... My Xperia T had the same sympoms when it was hard bricked....
I would have thought the battery had shorted out
Bang a replacement in

Every fault is not caused by a faulty battery. I know you fixed your phone with a replacement battery, but that is not the solution to everything.
If you had read his post properly, you would see the battery powers another device just fine. A shorted battery would surely not function at all.

Well today, I bought some distilled water and washed the phones motherboard with a toothbrush to displace any particles left on the board.
Now When I plug in the charger (with out the battery, as the phone does nothing with the battery plugged in) the phones LED blinks red and the phone vibrates once. It then goes on to repeat this process over and over again.
But my computer kinda detects my phone, as it tries to install the phones drivers. If I remember correctly the devices name on my computer is 'S1 FlashBoot'
But for the computer and Sony PC Companion to detect my phone, I have to remove the battery ribbon to let the phone start up on USB power, and then reinsert the battery ribbon when the phone vibrates and flashes its LED once, and then I have to remove the Button ribbon since, for some reason if the button ribbon and the battery ribbon is connected at the same time the phone shuts off.
Sony's PC software detects my phone, but since I cant press the power button due to the removal of the button ribbon from the motherboard, I cant repair my phone using the software.
Maybe theres something wrong with the power button/ribbon is having a few issues?
I also found some corrosion bottom right hand corner under the network antenna, and a severely corroded 3 segment ribbon, where 2 out of 3 segments were non functional due to corrosion,. As I tried to open the connector, I sneezed and accidentally ripped it.
Dammit.
It didn't work before I ripped it, so I wonder if I somehow fix this ribbon would it help solve a few of the above issues with my phone?
What does this small dinky ribbon do, anyways?

Found this post through google while looking for a solution for my Xperia Z.
My first experia also had the same problem, sort of. The battery would jump from 90% to 60%, then 73%, then 20%, then 71% and so forth.
I decided to update the system software, to which it turned off during the process. The OS became faulty, and it rebooted all the time, showing a weak red light, then a strong red light, turn on, turn off and so on. The authorized service replaced my battery, but I guess that's not your problem in this case, and I doubt it that it's a faulty OS. Because even with a faulty OS, it would atleast show the Sony or Xperia logo.
Now I have the same starting issues and I blame the ribbons I guess, since when I press it the right way, it suddenly accepts charge and boots up. Replace the ribbons, and you might be fine. Guess there's some short circuit.
I Dropped my A2 into the WC, lucky the phone didn't immerse in full only the side with the buttons, the accident was with the included case, the phone cant turn on.
I take it apart and I verified no water damage to logic board. battery usb connector, barely the buttons got some water , most like sweat in normal use.
I cleaned the contacts, re-assembly and nothing, plug into the PC and nothing is shown in ADB.
It's possible this killed my phone, I have recovered phones with actual wet logic board, pissed, etc, what happened do not use to require more than superficial dry with an towel.
curious I plug the charger and even do not show nothing.
Any Cues ?
@AcostaJA, put the phone in a can of rice over night...the chinese will come over night, repair the phone and eat all the rice
(I love chinese people, please this is only a joke, no offense intended)
The phone has moisture in it, it needs to dry out...the phone in a can/jar of rice is a serious proposal, do it !

I did, then I cleaned the buttons with contact cleaner and leave the phone opened in a shoe box under the sun, logic board was neves wet, so this is strange unless those buttons are really weak about moisture.
i bet that the bottom board, with the usb connector, got fried.
I would also check the display connector for burn marks as it's usually the first thing that fries when water ingress occurs.
It is a very strange situation, because, from the tests on youtube, the phone has a very good water resistance.

The Bottom board/connector was never exposed, Display also was dry when I take it apart.
i can't imagine how the phone fell into the toilet, submersing the buttons and not the usb port.

I saw this, also I verified the speaker is hermetic do not allow water in, the display is also sealed, indeed the only water that managed to get in was at the power/volume button, and almost minimal.
I'm considering to get another A2 and keep this for spares I I found no solution/cue on what's hapening.
A thing I noted when I first turn on the phone is this phone was somehow reluctant, it took me 3 tries to power on.

this phone is quite long, it felt almost sideway, the WC was not deep/wide enough.
did you check the buttons connector on the main board?

I removed the mainboard, the connector in the ribbon from the buttons also was dry.
Update, after checkint the battery connector I saw it was covered by phone's own thermal paste, I cleaned it properly with contact cleaner, I checked battery boltage with an multimeter it shown 4v, then I assembly the phone, and try to power it on, it vibrated and androidone logo showed, then battery logo appera as depleted, led blinks and the phone shutdown.
If I plug the charger it means only the phone repeat this cicle (androidone logo,-> then battery logo, then led blinks, the reset then repeat)s.

same behavior in fastboot, do not last more than 11 seconds between reboots.
I opened again and put in rice, I'll wait another 48h until try again, maybe there are still something wet there.

After some extra days to dry, still the same behavior.
Solved.
The issue was some mist at the USB port, cleaned dried, plugged, and turn on.
Working like ever, I resealed with silicone.

Thanks for the update. It would be really helpful for someone in future.
Okay. I really need help here guys. So long ago I had water damaged my phone and I got it working again. About 2-3 months later the battery started acting up and showing percentages in 10s and soon after could only use it when it was plugged in.
Now, whenever I plug it in it immediately shows the Huawei logo and starts to boot up. Which I don't like because I remember it used to show a green battery circle before. But nevertheless its in a bootloop now. The weird thing is, I can't use the volume up button method. I don't know why. It just carries on.
Maybe I should wet the power button with water if its been held down causing it to immediately boot up when plugged in? i dont know.
If anyone could guide me or suggest what to do I would honestly be so appreciative. Thank you so much!
Could be a hardware issue. Water is causing corrosion to metal parts and if there is still a bit water inside your phone the corrosion can damage parts of the hardware. It's risky to use the phone without drying it completely. In the most bad case the battery can be shorted by the water which can cause a battery fire or explosion.
Bring your phone to a repair shop if you're not able to open it by yourself. But I think there's no hope anymore.
You should've let it dry completely before using it again.
Don't put water again to parts of the phone.
If you're able to open it, disconnect the battery and check the logic board for corrosion and water.
If there's still water you can remove it early by putting the logic board on a piece of cloth and wait for a few days.
You can also try to clean corroded parts with pure alcohol and cotton swaps.
Get a new battery to be safe, check if the old one is misformed. If it's so, don't use it again - NEVER!
Li-ion isn't a funny thing, it can be very dangerous.
If there's a shortage inside the battery or it's physically damaged it can burn out. The technology is based on cells. If the cells are getting shorted each other, a chain reaction starts and inside the battery the current flow can get so high that the battery start burning. It stops when every cell is damaged and the voltage is 0 - it's hard to extinguish such fires. There are many videos on YouTube.
So don't make fun with this, just do something if you feel safe in electronics. If not, go to a repair shop.
Hi,
I'd like to ask you for some advices or maybe a solution. Lately I was updating phone by adb fastboot to xiaomi.eu rom V13.0.12.0.SKACNXM from 12.5 (xiaomi.eu), and doing little cleaning like uninstalling/disabling services by adb or Xiaomi ADB/Fastboot Tools the phone was working for a week or almost two, but suddenly by day it went off. I tried to boot it on, and it was working as always normaly but the thing is after half a minute it is going off again.
It works always in that way:
Booting -> working (ex doing photos, browsing or launching games) -> several seconds goes by -> turing off
The thing is that if im in fastboot mode it is not turning off at all, it could lay like that for hours
I've tried other chargers - the same
Downgrading back to 12.5 (after turning it on it is always playing against time, to turn on developer options -> turning off -> turn usb debug in settings -> turning off) - still same
Event after a downgrade, installation of twrp and doing solid wipe for fresh miui 12.5 (thinking that it was miui 13 fault) -> installed xiaomi.eu 12.5 - it is still the saaaaaaame
I'm out of ideas. I've called non authorized service in my town, asking if they had some devices with that problem, but no. Im in Europe and told them that I bought that phone by tradingshenzen - they told me that there is no guarantee that they could help (devices exported to EU are different than those to China's).
I bought my phone in november 2021 and everything was fine to that unfortunate day.
I'll be glad if someone could help me with this problem
Cheers
Hard to say; you change the firmware which compounds the diagnostic process.
Is it a firmware or software crash?
Try safe mode to try to rule out a 3rd party app causing it.
Can you roll it back to the previous firmware? However if it shuts down while doing that... it won't be pretty.
Otherwise, a failed battery, C port or mobo.
A battery may show a good voltage but not be able to deliver enough current capacity. Normally it would drop out at bootup though.
Play with it... hands on is probably needed here. A good tech could sort it out.

How to check if it is a firmware problem? When I installed TWRP then I could too operate for some time without turning itself off randomly.
I've tried safe mode and recovery mode but it's the same always unfortunately :/
Also I could say that I have washed phone with a little of water pressure (doing it time to time) the day before this issue. But it is IP68 waterproof phone, and nothing was loose in the whole phone case, just outward usb-c port like in any smartphone.
I read on some forums that mobo could be defective, but but should it boot up and run for a while then?

Water? Not good. The seals may or may not seal... don't test them.
IMEI is visible in phone settings. But the SIM card is not.
When i wash the phone water pressure is not that strong, I am aware of it. Phone cost me a little $$$ so I am not testing it's durability that much at all
Seriously I have no idea what is the cause of this problem
Seems like you have a few drops of water in the phone. Since the device is tight sealed it is really hard to get them out.
Please try this carefully, and if the mobo is alright then you should get away with this method (tried my self when I took my device for a dive)
1- you'll need to abandon your device for a full days or nights, longer better.
2- TURN OFF YOUR DEVICE AND LEAVE IT OFF THE WHOLE PROCESS, and take out your Sim card and leave tray open. This will open a gap in device for moist to leak out.
3- get any type of moisture absorbers you can find in stores. (Not rice, proper chemical moisture absorbers).
4- put moisture absorber in a plastic bag, and put the device in it, prefer to put a divider between device and absorber so it does not leave any marks on device. (Just in case, I did not use any dividers and it went alright with me).
5- leave device for a full night or 2. (Longer better). Plastic bag should be completely sealed with little quantity of air inside it (not so vacuumed to give little air movement).
***6- if you want to speed up process which what I did, then put the device in the oven with a temperature BELOW 50c. If you go higher than that then most likely you'll ruin the copper wiring, connections and lose your device permanently. (I put it in the oven). Do it for 15mins then turn off oven but leave device in it for an hour or 2, then redo process 2 or 3 times and leave the device in the bag for a whole night.
**** DO NOT PUT YOUR DEVICE IN MICROWAVE AT ANY COSTS, OR YOULL LOSE BOTH DEVICE AND MICROWAVE AND COULD LOSE YOUR HOUSE AS WELL IF IT CATCHES FIRE.
I'd this did not help (I bet it will help), then your MOBO is dead unfortunately.
My device kept turning off whenever the sensor (that turns off screen during calls) in use, for 3 days until I did this and it was perfect since then.
Hope this helps.
If you try this, please advise if it worked with you or not.

It's a thought but not enough. You need heat to drive the moisture out*, desiccants are useless for this. You need a hot dry room and airflow across the inside of the device.
Most of all the battery needs to be disconnected asap to limit the damage to the power buses, and pads bearing power.
The rear cover should be pulled... overkill is better than a corroded mobo and connectors.
Note: anhydrous isopropyl alcohol can be used as a drying agent but good judgment must be exercised. Any solvent can poison a lcd display, even the vapors and should never be used when a lcd is present. Residue from evaporation can happen if the alcohol gets in between the front glass and display. The alcohol must be allowed to permeate the whole assembly and connectors. It then must be removed in a warm dry room as much as is practical and allowed to completely dry.
*Heat drives out moisture ie a hot box which works even in high ambient humidity. Used to preserve cams, lens, surgical instruments, etc.
Old school.

That is excessive, not for only a few drops. I do not recommend doing this unless the device is soaked with water and dripping from inside. Because inexperience in doing this could cause more issues than a few drops.
I video recorded with my device underwater at depth of 1.5m for a few minutes, and I did what I mentioned above, device is clean and clear for more than 6 months since the incident. Not a single glitch since dried like I said above.

There's no telling how much is inside unless you pull the rear cover. Worse with the battery connected electrolysis can occur and rapidly destroy any energized conductors.If it's under a BGA chipset and causes damage, game over. Mobo mounted connector pins that get damaged will have a similar outcome. Once corrosion starts it is persistent and invasive.
The faster you pull the battery the better.
Leaving any water inside is not acceptable.

Whatever you say my friend, if you believe a wash without pressure caused a lot of water to enter in a tight sealed device needs all this to be done, maybe you are right. And maybe you are wrong. Won't harm to try what I said, it is his decision.
If it was me, I wouldn't open a costly device without proper tools. Unless it is my last option.

They aren't that hard to open. A rear cover is cheap to replace if you get clumsy, just don't cut into anything inside if using a razor blade. Heat gun, anhydrous isopropyl, guitar picks or old credit cards, a razor blade. Watch a couple tear down vids for that model.
With the battery connected the damage continues unabated if there's water in critical areas.
You assume the seals are intact... obviously a seal failed. The seals are flimsy and can fail over time or if installed improperly. There's no way to know the extent of the contamination without inspecting it. Regardless to dry it properly requires pulling the cover.
When my Galaxy Buds case fell in a cup of coffee (cream & sugar) I tore it apart on the spot. Flushed with RO water for the sugar then with anhydrous isopropyl. Couldn't disconnect the spot welded Li. Allow to fry for a day. Over 2 years later it still works and charges. Timely intervention matters.
Its happening with me too but for me its due to high temperature, when my phone gets heated it will restart no matter what I'm doing. Very few times it says limiting battery usage due to overheating. When I'm in my room it doesn't happen due to AC but in outside when i use maps it will heat and restart so my solution of avoiding it is trying to prevent phone from overheating. It may be happening with you as well but i don't know, the conditions may be different for both.

No bro its not related to ROM issue. Btw i m using eu latest weekly. I know its only due to heated weather because when environment temperature is good it never do like this. Only happens if it heats too much and i can feel that heat when touching it.

I live in tropical conditions (stable 35c all year long) and I do not have this issue, since you are on EU, I believe it is rom issue

You need to look at all the temperature sensors when this happens.
You may have a bad temperature sensor that's causing it to trip out at too low a temperature.
I have an old Galaxy A71 (Model SM-A715F) that I dropped around about 6 months ago, to which the phone completely stopped working.
I am aware that AMOLED displays tend to die entirely if they are shattered, however the device itself (not just the display) is completely unresponsive.
It appears to take charge when connected to a portable charger (seen by the LEDs on the front of it illuminating whilst the phone is connected), however holding down the power button and/or volume buttons does not cause the boot vibration. And there is no visible feedback on the screen.
The phone is running completely stock firmware (Android 11, One UI 3.1(?), I think), which worked fine before I dropped it, so it cannot be incompatible/broken firmware.
I have replaced the charging port assembly, as I thought that may be the issue, however I fear that the device may be completely toast, which would suck because I wanted to retrieve any un-synced photos from it.
Any help on getting this device to boot for long enough to get any photos off will be GREATLY appreciated!
Any drop sufficiently hard enough to damage the display can damage the mobo. BGA chipsets are especially intolerant of board flexing and high G loading. Inspect for loose connectors and mobo damage. A recovery service may be able to savage the images. Personally I would write them off.

Yeah, it wasn't a "bad" fall, but it must have still been enough to damage it. But it's weird how the device warms up a little as if it's charging normally though, if the main mobo is broken.

Power section is probably intact. May just be a loose ribbon cable, that's common.
Always use a good case. My N10+ would have been KIA long ago if not for its Bolt case. It's always in it. It's a very slippery fish without it
