Hi, as the title of this thread says, my mobile just died i dont know how but i cant do anything, i cant enter in recovery mode, i cant enter into fastboot mode, it wont recognize any command i put. The only thing it does, its that when i plug in the usb cable it turns on the green led and wants to start but when it gets to the "Warning: Bootloader unlocked" advice, it turns off again and starts again. I dont know if this can be fixed, i hope so. Thanks
PS: Sorry about my english XD

Just a guess, but you might have a bad battery. To test that, you can either buy or make a Motorola Factory Cable (google it) or get a new battery. Factory Cables power the phone directly from USB, bypassing the battery -- meaning if it works with the Factory Cable, the problem is with the battery. If it doesn't work with the Factory Cable, you might be screwed and need an actual repair from Motorola.
Also, try powering on the phone holding down all the buttons. That's how you access the boot menu, if you can get to that menu, you should be able to access fastboot and recovery.
And don't charge it with a PC, use the wall plug charger or a car charger. The phone treats a PC connection differently than the rest, even if the phone is off and only being plugged in to be charged -- it'll force boot/power on with a PC USB connection when it's turned off (it does for me). See if it'll take a charge with the wall/car.
My Bravo acts like this when that battery is really, really low and I plug it into a PC to charge when it's low....it also did exactly what your post said a year ago and I had to replace the battery....don't by a cheapo generic battery, I did and I regret it very badly (it has already gone out and doesn't work...the generic battery).

It might be the battery, because my mom dropped it into the water some weeks ago. I'll try factory cable now and see what happens. I tried holding down all the buttons but nothing happens. Just minutes ago I made it into fast boot mode, and now I'm scared of turn it off haha. I'll see what happens and let you know. Thank you for the reply!

Just leave it in a wall charger for a few hours then. Sounds like you might get lucky.
My Dad has dropped his in the toilet twice now (seriously, twice...figured he'd learn the first time) and on the second time, it had to be powered off, wrapped in a paper towel, and left in rice for 24 hours before it worked again (6 hours on his bed the first time). Rice draws out the moisture and is a cheap easy way to dry the internals of a phone if its soaked....just telling ya for future reference.
Mines been wet, but never soaked. These phones aren't hard at all to take apart and put back together (I repaired my Dad's cracked digitizer a few days ago in under a half hour...never taken one apart before then...the 22 #5 torx that are removed are damn annoying), so you could take it apart, blow dry it (warning: don't say on any one area for more than 5 seconds, you'll risk both unsticking the glue that holds the screen on as well as warping the motherboard), and use some PC cleaner or isopropyl alcohol (99% alcohol) and clean the board up being careful to not get alcohol on the screens -- (warning: alcohol can weaken certain plastics, but it's perfectly fine as a cleaning agent for a silicon based motherboard...alcohol also dries and removes trace amounts of moisture and can clean oxidation spots.
I can see oxidation on the battery terminals making the phone act like this. IRL, I install custom, solar powered, automatic iron gates, and the #1 repair I have to do is cleaning battery terminals. 30 seconds, a terminal post cleaner tool (glorified wire brush), and some WD-40 (acts as a sealant/water repellent) can make a non-functional gate into a working gate. Bad power flow is hell on electronics.
Just look at the EB40 mod guide. It has the exact same steps you'll need to do if you want to attempt cleaning the terminals, well, except for that step where you put in a better battery.
I water damaged my Z, the water got in through the power,usb flap.
I turned it off,I opened the device back cover,and let it in rice for 3days.
When it turned on it booted all nicely but when I tried to open the lockscreen the device shuts down.
Now I put it in a wall socket and it gives the red light,when i turn it on it vibrates but doesn't do anything,black screen.The xperia doesn't want to charge too.
The fastboot works,so as the flashtool.Only connecting to pc doesn't work.
I don't have warranty and no Sony centre in my country.What should I do?

Bad luck my friend, your phone is dead. Water probably damaged screen and motherboard. You can try to clean it with contact cleaner (contact spray) like this: http://www.wd40specialist.com/products/contact-cleaner/ but don't expect miracles.

I find it a little too fast to say that the phone is dead.
Do you know how much battery charge you had left? Because the Li-Ion batteries have a safety circuit that shuts them down when the battery voltage gets below a certain point. The battery still has some charge, but only to maintains its health for a limited amount of time, and you would have to find a shop that can "jumpstart" it. Your battery is in "safe sleep" if it shows 0,00 - 0,10V or anything like that.
Replace the USB port if the RED light doesn't light up at all, or blinks irregularly. If the phone shows the red led constantly, but doesn't want to turn on, measure your battery and charge it directly. There has to be some shop nearby that works on circuit boards, and if you ask them nicely and bring them the parts, they will surely change the port for you for a few nickels . But that's only if you' re sure that the battery is in good condition.

Oxydised components on motherboard are probably shorted out, I see this so many times in repair center. The best solution is to first clean motherboard with contact cleaner and than try to plug battery back and see if the battery is charging. Shorted out motherboard, in 80% of cases, is dead motherboard.
My motherboard is perfectly fine.
I opened with my friend my Z and his Z.He put my motherboard in his device and his Z worked with my motherboard and all my files were shown there. So i guess my screen is dead? What do you think guys?

He wanted to change the battery too but he said it is much harder than changing the motherboard.
My current symptoms are:
When i touch the power button the red light blinks three times.(that means the battery is empty)
When I press volume up+power button it vibrates three times.
The device connects to flashtool,adb
So, my Z1 is more than 3 years old and I already changed it's battery, which means that it was opened before and probably is no longer waterproof. So, I went to the beach and used a waterproof bag (what was supposed to be a waterproof bag) with the phone inside. I had tested it some times and it worked, everything inside remained dry. But on my second day using it with the phone inside ssome beach water went in and it was enough to brick my phone.
The day before this I got a number of a girl I met, but didn`t made any backup, so it is possible to get my contact list of a watered bricked phone? I don't even want to get the phone back, just the contact list... The phone doesn't turn on, when I plug the charge the red led turns on and stay on. Can't enter in fastboot or flashmode, hrd reset doesn't work. I already opened it and dried its inside and left it ona a closed bag full of rice for more than 1 day.
Tried the hard brick fix but I just can't make the test point thing wrk, computer won't recognize the SEMC DEVICE.
I don't know what else can I do, I just want my contact list, there is any way to solve tis, maybe some software?
PLease help!
Dry phone with rice or silica gel, and plug it in wall charger to charge phone, mabye the battery is drained and go to Sony PC Companion and start software update. That could help to unbrick phone. For contacts try using Google accounts if your phone did back up automaticly.
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.
Hello
Since a few days, my phone wouldn't charge, it did not detect anything when connected. I have tried different cables and chargers with no result.
In the notification bar the phone was giving a message that the phone was in reverse charging mode, whilst it was not connected.
When i tried to change it to charge only it immediately changed back to reverse charging.
The only way i could charge was by turning it of or restart the phone with the charge cable connected., but After removing the cable i couldn't use it anymore, and the notification of reverse charging would appear again.
I have tried to clean the port, this would work sometimes, the notification would disappear but this was temporarily (max 1 minute, i've read that for others a longer periode).
I found a solution, i hope its not a temporarily one, but until now it alright:
I removed the USB port, disconnected and cleaned every connector en blow on them, also on the back of the USB port (black piece attached to the bord) there was this sticky glue thing (i think its glue), i cleaned that part, some piece of iron plate was bended somehow, i don't know if this was supposed to be like that but i corrected/bended it back a little. After this it started working properly. Somehow I think this problem is due to moisturized parts.
You can watch how disconnect the USB Board on youtube.
I wanted to share this with all, in the hope it will come in handy for somebody.
Huawei stuck in reverse mode fixed..
I have encountered this problem in my mate 10 pro and I think I repaired it .. You have to clean the charging port using an alcohol and a small piece of iron .. The piece of iron should touch the piece that enters the cable and the top side of the hole together. You have to be careful and I am not responsible for any other problems you face.
Thanks for the help, I am experiencing the same thing on my Mate 10 Pro. I will have to try the alcohol trick when I get home.
