[Q] Xperia U usb/battery behavior - Sony Xperia P, U, Sola, Go

First off, if this has already been addressed I am sorry I couldn't find anything about this.
My wife's Sony Xperia U has been behaving quite weirdly lately and is about to be thrown in the garbage very soon, it is (or the battery is) most likely 87.35% dead but I want to ask here in case it would be something else and could be fixed before she buys a new phone.
Short backup story, she works at a farm and gets a lot of dust and stuff on her phone, and once when she cleaned it up it died for 2 days and the water indicators are now red (duh). It wasn't booting up or charging, the red DEL wasn't lighting up either. But then after a while I toyed with it (literally torn it open because I broke a screwhead and had to force it open to see if there were any apparent damage, but I didn't break the components, just forced on the plastic frame), I didn't find anything, but when I closed it down I tried to plug it in... And it charged. Then it worked perfectly fine for about two weeks. Two days ago it died again.
Here's the real problem: When the battery is completely depleted I can charge it (the red DEL shows up and all) but as soon as it got enough charge to boot up I am unable to charge it in any way whatsoever. If I boot it up the DEL won't show and it doesn't charge, if I don't boot it up the DEL shows for 2 seconds when I plug it in then it goes off and the screen shows the Sony logo for a few seconds then turns off. I am no longer able to charge the phone until we wait for the battery to be depleted again, then I can charge it (after over 30 minutes of trying). I did a factory reset but no changes. Oh and computers no longer detect the device, it worked last week but not anymore.
I suspect that the battery is the issue, however it does charge completely when I plug it in while it is depleted so it is not dead (could be damaged though). Since it charges sometimes it must not be the USB port (I have inspected it and cleaned it, looks fine). The cable/charger is all right, it works perfectly fine on everything else (and we did try another cable to be sure).
Does anyone have any idea of what could be done to fix this if it is possible to do so without buying/changing parts? The phone is no longer under warranty and my wife doesn't want to invest money in the device, if it can't be home fixed then she'll buy a new one. I know it is most likely that nothing can be done but I'm still hoping since she really loves this device and I want to fix it for her if I can.
TL;DR: Phone is all right, battery is most likely almost dead, I need to know if it can be fixed or not before we buy a new phone.
Sorry for the long post, and sorry again if it is obvious that nothing can be done (I still hold on on my hopes, just in case). And yes I'm Canadian, sorry for being sorry.

Video
In case anyone wants to look at my issue here is a video of what happens when I plug the charger in when the battery is charged and the device is turned off. You can see the red DEL for a few seconds when I plug the cable in.
If anyone needs more information (in the event that there is still hope) feel free to ask, of course.

I didnt think battery could do such a mess like that. Im afraid your phone charge controller had been damage by the water. Could you enter fastboot or flashmode?

Of all the things I have thought of, I didn't try these two options, but the device is rooted and its bootloader isn't even unlocked, can I still enter fastboot or flashmode?

You should be able to enter flashmode regardless of bootloader condition. Did you try it?

Just tried, but after the DEL bar turns green nothing happens (the phone either boots regularly or not at all), I have read that it needs to be over 70% charge and it is around 40% so I need to wait for it to be depleted to charge it again to 100% (because for now I can't charge it at all as I explained in my first post)... What would you suggest me to do once I can enter flash mode?

By DEL did you mean LED? Im sorry just confused. If the led turn green an stay like that for around a minute then your bootloader certainly not damaged. I suggest you flash stock firmware using either Flashtool or SEUS.

Haha yeah I meant LED, DEL is in my native language and I switched them up, sorry! I have fully charged the phone now, and I can't seem to enter flash mode (or w/e the name), I am supposed to connect the USB cable to my PC (but not to the phone), power down the phone, press and hold volume down then plug the cable in, but the only thing that happens is the LED bar turning green for a few seconds then nothing (if I keep on holding volume down then the phone boots normally, if I release volume down then the phone shuts down after showing the Sony logo).
On the side I am trying to download the Oneclick root thing I've heard about, see if rooting the device and installing a new ROM can help...

Seems like you dont have proper driver on your pc. Btw if you succesfully rooted your phone and in case you had unlocked bootloader, i suggest using latest nightly CM11.

It seems that the version of my wife's phone cannot have its bootloader unlocked so I can't root it, however I did use the provided program by Sony (PC companion or something) and have upgraded the device to Android 4.x, it has been working fine for nearly two days now, I hope that it will hold. Last time I had "fixed" it it had stopped charging after about a week for no discernable reason.
I was unable to enter flash mode but I still want to thank you as it were your advice that made me think of upgrading the phone.

Good to hear it. Hope it will stay that way. Btw, if you are unable to unlock bootloader you still can root it in case you had sim-free phone. After you root it you can still install custom recovery and other custom rom that can be use on stock bootloader.

Question... How were you able to update the phone through PC companion if the phone is not being detected and only charging when connected to the PC?

Sorry for taking so long to answer! Well when the phone's battery is full it gets detected by my computer so I could upgrade it. But unfortunately it did not fix the issue. The phone would work as normal for a while then suddenly die and I have to wait a couple of hours before I can charge it up and open it again. So I guess it is officially dead.
My wife just got a new device (Moto G) so I guess that all's good now. She was able to back up her pictures and data, gladly.
Thank you a lot for your help!

Oh well its a paperweight then haha. Seems like its a problem with the phones board, sony has really gone to the dumps after parting with ericsson. I never had any issues with my X10 back in the day cept for bricking it myself time and again with bad flashed lol.

Yeah, what makes me sad is that she really loved the device (Sony's UI and all), she wanted another Sony but there were none at the shop and got the Moto G but she seems to like it too! I got a Nexus 5 to replace my LG Optimus L7... Damn thing was slow as hell! Now it's almost faster than my 1300$ laptop haha!

Phone bricked, cannot charge, need help ASAP

I need help with this NOW if anyone can. I figured I'd go ahead and make a thread for it so it would get seen. I was trying to update to 2.1 and something went wrong. Long story short the battery drained and now even when it's plugged into the wall all it does is flash its little red light. If I can get it to charge I think I can get things working again but as it stands I don't even know if it is charging. If I have it plugged into the wall and remove the battery the led turns green. If I put the batt back in afterwards it will go off after a bit and eventually "turn on" (in this case that just means that the screen comes on but is completely black but backlit) but there is no led indication at all so i don't know if it's charging or what. It doesn't seem to be. I really need help asap. Thanks in advance.
Silly question perhaps.. have you tried putting it into flash mode for SEUS (phone off hold back key, plug in USB cable)...?? does it register the phone?
Open pc companion hold back button and insert the micro Ian until it says stop it should then tell you your software is already the latest but if there's a problem you can use the repair option. Hth

Tried it just now, nothing.
My suggestion would be to plug it in for a few hours then try again. Or take battery out completely and try the back button without a battery. Might work. Might not. Sorry. Doubt the phone is bricked tho.

Just out of interest how long have you left it on the charge for? Because the red light flashes while charging until 10% and I remember once when my battery fully drained it did that for a few minutes until phone turned on again. Leave it for a while if you haven't done so.
The reason I ask is, incase you saw red light flashing and took it off charge straight away thinking its faulty? Like I said it sometimes takes a while to turn on fully when battery has died.
Edit: I know this is unhelpful, but that's why when you update via SEUS it says to ensure battery has 50%

I got he same problem 3 weeks ago. i could not get the phone to boot anymore even after trying all the unbrick method available here. so i sent it to sony ericsson service and they changed the motherboard.
okay, been charging for a while now and still have the red light. Pretty confident it isn't charging.
Plz try another usb cablr. I know about 20 people whoms usb cable accidently died and the phones cannot charge anymore ....

But the phone won't even boot. Will the battery charge while it's off? or when it's on a black screen? I know 2.1 lets it charge when it's off now, but the OP said the update screwed up.
Other suggestions that may take some time:
1. Find someone else who has an X10 and charge it in their phone.
2. Bring it to your phone provider and ask them to charge it.
3. Bring it to your phone provider and exchange the battery (temporarily?).
4. Buy an external wall charger (one that lets you charge the battery directly, not in the phone).
I ended up bypassing the phone and charging the battery directly via a macgyvered usb cable. Don't ask. lol. But I got it charged enough to use the se update tool and restore it back to the original rom. I'll try the update to 2.1 later after I get this thing charged all the way up. Thanks guys.

[Q] S II dead :(

Hi all. I have a big problem. I placed my phone onto my desk before sleeping (my battery was +/-55%). When I woke up my phone did not want to go on. I tried charging it for 3 hours with my 2 pin charger and it still didn't want to come on (the charging battery animation didn't even show). I also tried charging with the USB cable via PC but that didn't help. I used my multi-meter to check if the battery was working and it showed that it contains +/-3.4V (battery is rated 3.5V). I tried to boot up into recovery mode (volume down + home button + power button) but it still didn't come on
I bought my phone at the beginning of the year (brand new) and it has been working with no problems until today. I have essential data on my phone (phone book, messages, apps etc) which are really important and I wouldn't want to lose them. Help would be much appreciated.

But how can it get bricked out of the blue? Was working perfectly night before happened. The only app I installed was Angry Birds: Star Wars (officially from Play Google Market).
Hard to say. Phones (like any other electronics) can die for all kinds of obscure reasons.
Service centre or JTAG repair; if you choose the latter option (assuming it can be JTAG'd & it's not a hardware issue), you could ask the repairer if they can recover your data. Might be possible. Service centre will wipe it if it if it's not a hardware issue, and if it is, they'll replace the MB which means you get new internal storage/you'll lose your stuff.
LOL.
Its happened to me and its just a BUG...
you may have 100% of battery but the phone is showing like 50%(fake)
put the charger into the phone hold the bottom of the usb (the last piece .. of the charger) and move it

Same Issue
I have the exact same issue with my i9100. I woke up and it was dead. No recovery mode, no download mode, nada...nothing comes up on screen. It has been a little buggy ever since the ICS update but it has always worked eventually. I put the battery into my friend's phone and his worked fine. I am really hoping somebody has answers and it is just not "dead". I never used a ROM or anything, it's killing me that a $500 can just die overnight like this. Any help would be greatly appreciated!
If your phone is still under warranty, go to Samsung service center.

I can not believe that just happened overnight, the only possibility is that you put some of the room's, if you have a warranty on the device, you can send it to the service and just hope that they will accept it and serviced

[Q] Phone slowly becoming unusable, Recovery is unaccessible.

I have no idea what went wrong or where. One day a few apps starting force closing. Then I got weird unlocking problems. Now google play crashed consistently on any search, as well as ****ing settings. I ****ing hate this phone.
-Rooted and unlocked via freegee.
-Installed clockwork over adb(everything was fine at this point)
-Flashed a few different ROMS
-Flashd beanstalk, and then the problems started.
-Can't get ****ing adb to connect no matter what so I can't flash a new recovery
-Considering beating in my phone with a bat.
Anyone have any suggestions for getting recovery working again? Clockworks app doesn't work, similar to what this fellow went through (and apparently solved) http://forum.xda-developers.com/showthread.php?t=2258671&highlight=can+t+boot+recovery
Haven't tried LGNPST because I have no idea what the acronym stands for and no one says what it is.

I've exhausted everything I could find through the teenybin thread. LGNPST and teenybin gave me back fastboot, but I still have no recovery.
Oh yeah, and a sweet bonus: My phone refuses to go past the boot screen when booting and adb on both my desktops refuses to recognize my device! Anyone want a free phone before I smash it to bits against my face?
Update: For all you poor fools who are following the same path, heres what happened.
Left it plugged in all night and it continued to flash red for a while, and then show a full charge screen, then turn off. Repeated this throughout the whole night.
Come morning I perform a hard battery pull via this thread: http://forum.xda-developers.com/showthread.php?p=45849420#post45849420
I wait a minute with the motherboard connector disengaged. Hold power button for 10 seconds. Plug back in, absolutely no change in my situation. I tried again for about 5 minutes, ditto.
So in conclusion, I broke my phone because I installed a custom rom and LG didn't want me to. I hope whatever team was in charge of developing this phone burns in hell like they so sweetly deserve.
**** you LG. ****. YOU. I want my ****ING money back. You make **** PRODUCTS.

Yeah its my fault for installing a custom ROM. You wouldnt be saying this if a desktop or laptop magically stopped working after reinstalling windows or linux. If those were as randomly, stupidly risky, people would be ****ing in arms at microsoft, as they rightfully should be at carriers. Whatever man.
If you can't access recovery or the phone will not boot then adb won't work. You said that you do have the ability to use fastboot though. Have you tried flash twrp from fastboot?

Why you install recovery over adb? I mean, when you unlock with freegee it installs the recovery you want (cwm or twrp), so no need for adb.
Have you tried to KDZ a stock rom and do a hard reset?

You got frustrated due to a lack of patience. You can flash recoveries via fastboot. If you actually searched well you would have seen that.

Doesnt work, and never did. The ****ing phone drivers are so ****ty and proprietary, no computer I used would recognize my phone.

You can melt the software side of these phones so badly and still recover with the Qualcomm tools after the fact, it's not even funny how bad things can go before no return. Flashing a rom didn't do this, period. I want to believe you just suffered from a fluke hardware failure. Even more so it sounds like the USB connector went ape and continued wigging out from there.
The universal drivers also work perfectly. Considering in every way this is the nexus 4 with an SD card slot and a better LTE amplifier, everything you're ranting about is invalid.
The phone is a sanctioned, flash to hell and back model. You need to do some soul searching and find out where YOU went wrong. Or at least get an el cheapo multimeter out and start checking continuity. If it turns out you broke the charging connector or the battery connector off of the board you can STILL be saved. Just put in some effort and try to find the root cause. Screaming and cursing on a random corner of the internet isn't solving your problem
Making up crazed excuses isn't doing any service to you or the other forum users either. Especially the driver ranting. They work flawlessly. Hell even the generic Google provided SDK abd driver works.
If you figure anything out we're here to try and get you back to good.

-edit- and leave the battery disconnected for awhile. The reason I suggest holding the power button while battery disconnected is in the hope that it will drain any remaining current out of the phone. There's no documentation to say it does or doesn't. So let the thing sit and be absolutely sure it's got a chance to reset. And check the battery voltage to confirm if it's dead or not. Since the contacts will be right there when it's disconnected...
That red light flashing / lg logo when plugged in is exactly where my phone and others was when needing a battery pull. It's fixed every phone I've heard of in that state. Try it again?
The same thing happened to me twice before. Both times I was able to recover my LG you get back into my recovery screen. What works for me is using Lgnpst back to stock jb. Next I flashed both teeny bins. Immediately after flashing the teeny bins, I open my LG up and pulled the battery. I waited about 10 minutes attach the battery back into the LG. Booted to the device and a factory reset my holding the power button in the volume down button. After the the device finished the reset I was good to go and my LG back to normal. This is what works for me give it a try... And good luck.

Well, another free day off, guess I'll give it a go again.
The connection of the battery to the mobo is most definitely intact. Pulled the plug to the mobo for ten minutes, plugged back in.
It still just steadily flashes red whenever I charge it. Nothing.
I'll try holding the power button while its disconnected, but I don't have a multimeter to check voltage.
Edit: Something changed. After sitting with the battery disconnected and a rubber band around the power button for 20 minutes, it showed a battery with a charge icon, then nothing. Havent had a screen for awhile. Pressing the power button, nothing. Holding it for awhile gets the full-charge battery, and if I keep holding it, the google symbol, and then nothing. I guess I'll try pulled the battery for 20 minutes again, Maybe it didn't fully discharge?
Edit 2: I've been informed that after a hundred battery pulls, the battery probably has something physically wrong with it. ****ing phenomenal goddamned phone here!! Why do I pay tech companies money for **** again?

if they say no dont lose the hope
its a great phone, and as you see you are the only one with this problem
and with that angriness you will do nothing, remember you and only you are the responsable for any damage your phone suffers, not the developer of that rom

[Q] My ZU wont switch on. Red LED

This morning, my Z ultra died on me. It wont start, no vibration, no use pressing vol + power buttons and the red switch. I was neither rooted or bootloader unlocked.
When I tried to connect it to my laptop (Windows 7), its shows as a USB device. The red LED flashes up, the computer finds it and then lets go of it again. Again in a few minutes, the red LED goes up , the computer makes the connection sound and then the red LED goes off again. This cycle goes on and on.
I cannot use SEUS, Flash, Fastboot or do anything. I have checked various forums and apparently I have not hard bricked the phone as the LED still works and the computer recognizes the problem. But no one has given any concrete solution.
When I connect it to the charger which came with the phone, the red LED pops up and then goes off again. I dont know if its charging. HOWEVER, I have used another Chinese Travel Charger, and then the red LED stays solid as if its charging. I dont know what it means.
Please help. I spent a lot behind this phone. I dont want to be left with a brick
It's not an issue if it's completely stock is it? You have your warranty, but i understand that i sucks to have it shipped in for repairs for god knows how long. I had a similar issue some time ago, but i'm bootloader unlocked and what not, so that was pretty easy to fix. You're completely stock though, so it's a little harder to do anything.
What happens if you hold VOL UP when you connect it to your computer? Does a blue LED light up? If yes, does it stay on, or does it disappear? What happens if you hold VOL DOWN when you connect it to your computer? Do you get a blinking LED and then nothing? That's normal, and it's going into Flashmode. If you can get it to stay in Flashmode you'll be able to re-flash a ROM in Flashtool. But be 100% sure to have enough battery, or else you'll be in danger of hard bricking it.
So..
- Plug the wall charger in and charge it for a couple of hours (2-3 hours)
- Try to kick it into Fastboot (VOL UP when you connect it to your computer). Look for blue LED.
- Try to kick it into Flashmode (VOL DOWN when you connect it yo your computer). No LED.
Hi LordManhattan. I dont have any warranty as I brought it from a local reseller .
Whether I press Vol UP or vom DOWN when I connect to the laptop, a red LED pops up, there is a connection sound and after that the red LED goes off and and there is a disconnection sound.
If I leave the phone connected with the computer, the phone gets connected after 2/3 minutes, there is a connection sound and then there is a disconnection sound again . Any clue what I can do :crying::crying:

just a small note or two:
Flashmode the LED should go orange, then blue then off within about 1second then it is in Flashmode
To get into either of these modes the phone has to be powered fully OFF, press the red reset button before charging to make sure, then again just before the above steps.
It sort of sounds like a corrupted loader

Have a good read of this? http://forum.xda-developers.com/showthread.php?t=1849170
It would suggest that the battery is flat. Let it charge in the wall plug for a few hours and see what happens
I have let the phone to charge overnight with the charger that came with the phone. As I said before, with that charger, the red LED would turn on and then go off again. I will hopefully try the Chinese travel charger tonight with which the red LED remains solid.
The funny thing is , the phone had about 80% charge when it died. This is so weird :'(

Nothing. Its like as if the phone soft bricked itself, probably by auto updating or something

Have you tried the reset button under the microsd flap? Press and hold for 3 secs.
I did read another user had an issue where the screen blanked for around a day, he left it plugged in and came back to it about 6 hours later and it was fine again.

I tried that and basically all the other normal options. No use. The computer recognises it as a USB Input Device and for a second or two, the red LED comes up. Same thing when I am charging

It's a battery issue most probably. I guess it doesn't show anything. Is your battery removable?
I still have not opened my phone. I am looking at all the other options first. If everything else fails, I guess I will have to open my phone

I know it isn't the best choice but I would suggest getting it to sony repair. So that your waranty isn't voided (even if you have bought from a local store you still have waranty

Warranty exists with Sony for first year, no matter where it's bought, very true.

+1 contact your local sony, i had a similar problem, no fastboot/flashmode. locked bl/not rooted and my led only flashed red and occasionally solid red then nothing. plugging it into computer continuously played the disconnecting sound.
most likely hardbricked.
i also purchased my xzu from a local BST but as long as you have your imei, contact sony and theyll tell you if you have warranty. they required me to send in proof of purchase as well but like most say "play stupid" ( i said i received it as a gift and they said it was fine)
i got a brand new XZU after a week and a half sending it in.

Thank you! One or two years ago my Z Ultra's screen cracked and I got a new phone. Decided to use it again, purchased a new screen and replaced it myself today. When I tried to move to AOSP (had root, bootloader unlocked, backup of TA partition), the phone bricked. No SONY logo, nothing. Did what you said above, Xperia Companion recognized the phone in flashmode and is now downloading the newest stock rom. I was so afraid of a hard brick, that living with latest stock without root doesn't seen so bad now hahaha
Hey Friends, I have exactly the same issue. The red led just flashes up for a couple of seconds and this cycle continues. My battery was a bit swollen up and the back glass cover opened up a bit. Still battery was working fine. Two days ago I tried nougat aosp on it and after leaving it idle for 2 hours, it was bricked. I can enter into flashmode and flashed stock LP as well as KK but it does not boots up. Is it definitely battery's problem? If yes, where can I buy original or near original battery for it?

The battery is dangerous and should be removed. Be careful because the battery can burst into flames if the bloated cell get punctured.
Use tools with caution and take your time.
Lipo cells expands as a first safety trigger. Instead of going strait to venting or venting and burst into flames.
Its a safety feature if they are charged with too high current or if the cell is drained below its 2,22 volts and is brought back to life with a normal charger that puts normal current on the cell. Then even 400mA in this scenario is way too much current to start charging a drained cell with.
But the battery should not be the issue that your phone is not booting. How did you flash stock rom? With Flashtool?

[Q] My Z Ultra won't turn on or charge at all? read please

i was swimming with my z Ultra the other day, unfortunately when i got out of the pool i noticed charger port was open and there was some water in it, i let it dry for a couple of hours, it stopped turning on, so i opened everything in the device (except the screen i didn't remove it) and let it in the (rice trick) to dry for 3 days.
When i reconnected everything and turned it on IT WORKED!.... until the Sony logo it kept rebooting (btw the device was rooted so i managed to go to the recovery menu & the touch was working) but after like 10 minutes the device just died... couldn't turn it on, could'nt connect it to my laptop... it just died
What should i do? is there any hope?

Maybe try replacing the battery. Or if possible connect to charger and leave it there for a day then connect pcc in flashmode. Before that relock bootloader.
