Xperia U-not turning on, red LED stay 1 second only - Sony Xperia P, U, Sola, Go

Hi guys,
I am currently trying to repair my friend's ST25i Xperia U, he encountered random crash and the phone won't turn on. I have tried to charge the phone but no reaction from the phone itself. if I pressed the lock button it only turn on the red LED for a second and nothing happens. I think I am having a problem with the kernel that it won't let the battery charged.
I am familiar with flash tool, when I tried to flash the device will not get into either fast boot or flash mode. IF i connect the phone to PC via USB(holding down up/down for either fastboot or flashmode), it only turn the red LED for a second.
anyone can help? I am currently trying to only charge the battery via universal battery charger, hoping that it is charged and can enter fast boot or flash mode so i can flash the device.
my friend said that it was running android 2.3.6, having a problem and sent to repair center upgraded into 2.3.7, then this random crash happened. I want to flash it to ICS by the way. I had the stock rom ready to flash.
Is there any flashing method that does not require a battery?
sorry for the long post, I hope you guys can help me with flashing

Load the stock ics ftf in flashtool.
when it asks to connect the cable
HOLD volume down key and connect

there is no way you can flash the phone without battery and the is the led flashing 3 times when you press the power button?
the problem is with the kernal and it is not charging the phone in offline mode and the only way is to use the Universal charger or flash the phone by using any other battery from a similar phone report after you do it

well the universal chraging method did not work, and no one uses xperia U here. hard to find a battery. can you confirm if using battery from similar phone will work?
regarding the led--it only flashes once, and red. this happens when it is plugged into pc/charger.

Remove the battery out of the device and leave it for an hour without the battery and after that press and hold the power button for 60seconds (without the battery) after that insert the battery and try to enter flash mode "have the FLASHTOOL ready to flash a rom"
IF it doesn't work
Just as a last try you can TRY REPAIR using Sony Update Service(SUS) and if it doesn't work either you have to report the service center... they will help you and if it is still under warrenty you can get it done for free too...

battery drained
have you done anything that couldve drained the battery fully ? if so the solution is to continuously charge it ... it might take upto 16 hours or more happened to mine now fixed

did it woks ? after charging your mobile for 16 hours ?

xperia x10a not boot or power on, just continuously vibrating.

hi!! my xperia x10a not boot or power on after flashing. the battery charge was poor during flashing and now the phone doesn't boot up, when i push the power key the phone vibrate but no power on and then the phone vibrate continuosly.
i charged the battery and refhlasing the phone using flashtool but nothing at all.
what can i do?
need help please!!
What did you flash to it exactly? Try flashing the original firmware.
i flashed the phone because when i update from 1.6 to 2.1 the phone restarted it self everytime! i need to get an externar charger to charge the battery before reflashing to the original firmware.
Flash back a 2.1 or 2.3.3 firmware, see if it helps, if it is atleast coming on a bit, do a repair via SE. Do check the files you're using and make sure they're legit before flashing them to your phone.

I had the same problem.
Infact what I found is that charging itself need the firmware to be properly installed.
You have 2 ways to fix the problem.
First is that find a frnd who have an x10 and put ur phone battery into his and charge it for sometime.
Second is open flashtool, remove battery from ur phone, then connect the USB cable to PC and ur phone, and then press the back button and hold it and then insert the battery.
U will see the green light (means the phone is in flash mode) and also ur flashtool should be detecting the phone.
Now keep the phone like that for atleast 30 mins.
When phone is in flash mode, it actually charges the battery. (thats what I did).
After atleast 30 mins, remove the phone and check if its switching on.
All the best,
Also, while ur flashing a new ROM, always make sure that u wipe ur battery stats...
i charged the battery and flash the phone with flashtool to 2.1 and 2.3.3 but still the same problem.
by the way, the green light power on even without hold the back button, is like always be in flash mode.
+1
i got the same problem as you. When i press on/off button, it vibrates and green led flashes once, but then nothing more happends.
I tried to put in it flash mode, but it bootloops when i do that.
this is exact my phone problem, but i can't find any solution!
do you have any sugestion?

[Q]Can't boot xperia x10 mini pro in flash mode and can't back it to stock ROM

Hello comrades,
I have xperia x10 mini pro. I rooted phone with Flashtool and installed CWM. I tried to boot it in flash mode (turned off phone, back button held and plugged in USB into the phone), but what I get is that my phone turned on always, like that I pressed Power button.
Earlier I couldn't boot it into the flash mode and I got that I charging battery, but after I installed CWM, phone always turns on.
Due to, I can't re-flash it because it always turns on. I tried with flashtool, PC companion, SEUS but all software need that I turn off phone and then hold back button and plug in usb and what I get is turned on phone. Please help me how to fix this problem.
I would like to re-flash it to stock 2.1.1.A.0.6 (2.1-update1).
Phone turns on even if I just plug in usb to phone (one end is in the PC and when I plug in other end into the phone, phone turns on). What is wrong guys?

Happened to me b4 if u want to repair with pc comp just remove the battery till u reach connection step then quickly connect battery and cable (nvm the cover) and hold back button when connecting if u do fast enough will work
sent from my u20i xperia x10 mini pro running mini cm9 3.0.2 on nAa ics 3
THX nAa. VERY MUCH!!!
Leave your phone plugged in and press POWER-HOME and BACK all together, as soon as the screen turns completelly black (backlight off too) releast POWER and HOME, and leave the back-button pressed, that will probably work too.

Can you explain me a little more detailed, i didn't get you very well. I am noob
How do you mean until I reach connection step, where should I reach connection step?
You take out the battery, then you go into PC Companion and follow the steps to repair your phone, until it asks to connect your phone in flash-mode.
Then do as he said (put the battery in etc.)

What do you think, what will happened if I wipe it using CWM? Can I brick it on that way?
If you mean formatting your phone, so you don't have a system on there anymore... that probably will give you a brick. Flashmode is a hardware feature, implemented to install firmware and enable reparations to your phone's software.
Deleting everything you can will not magically solve your problem, as far as i know.
It might help if you get mad at the phone and abuse the back-button by repeatedly pressing it when connecting the phone.

Does this mean that I have hardware problem. Phone works without any problem.
Somehow it doesn't detect you pressing the back-button, maybe there is some dust or dirt inbetween the contacts or something, since you flashed sucessfully before i don't think it's a serious hardware-problem.

I didn't flashed it before, I couldn't do that. I couldn't unlock bootloader, because I couldn't boot it in flash mode (phone just show that battery charging), after installing CWM now phone even don't show that battery is charging (it turns on when I plug in USB in the phone without holding any button). This is nightmare!
You are still on the original firmware then?
I mean, your phone still works?

Yes, I am on original firmware and phone still works, but I have problem to boot it in flash mode. When I plug in USB cable in the phone it turns on, like that I pressed POWER button. I don't press any button, but when I plug in usb cable 10-20 seconds and phone is on.
Yes, because your phone detects the usb-cable getting plugged in, even when it's off, it thinks you want to charge it, so (normally) it loads the kernel in order to start the charging-process, that is normal behaviour. I have been on a kernel that didn't support that feature, and it booted into the full rom before it started charging.
In short: the usb-port also functions as a power-button, sort off
Does the back-button work normally when you're on the firmware? (Like, open the app-drawer, pressing back-button should close it?)

Yes, the back button works perfect, closing apps (not close apps, but back to the phones "desktop"), back to previous pages in browser...
I am concerned because, before I installed CWM , when it was OFF and plugged in on USB, phone just showed black screen and when I clicked on some button I could see that battery is charging, that was all. Now, when I plug in USB it turns on like I pressed POWER button.
And off course never booted in flash mode because it turns on

What is app-drawer, I don't know what is that.
oh, that's the bit where you find all your installed apps, the grid you see when you press on the little triangle on the bottom of your desktop, or swipe up on the desktop.
I honestly don't know why your phone won't go into flash-mode though. Maybe try to take out your battery for about 10 minutes so your phone gets rid of all charge and static, and then try again.

I solved problem about POWER-ing on when I plug in USB. I installed new ROM "MiniCM7Pro_V21_Paul_XXX" via CWM because I didn't need to boot it in flash mode and now when I plug in USB I got that it charging battery and orange led diode.
But I can't boot it in flash mode even with new ROM, all the time orange led diode when I hold back button and plug in USB. I wiped out all date except something about "battery" from Advanced CWM options.

[Q] Xperia Neo V bricked after flashing AOKP build 5 kernel

Hi. I was running Jelly Bean AOKP Rom build 4 on my Xperia Neo V, KXP kernel and yesterday I thought of upgrading the ROM to Build 5. But after flashing the KXP kernel in the AOKP JB Build 5 package my phone got bricked. Now it doesn't power on.There's a slight vibration when I push the power button but then nothing happens. I can't even connect it in Flashmode or Fastboot mode. I can't even go into recovery mode. The phone is completely dead. The phone is not detected by the PC. Please advice me what should I do now. Is there any way to bring it back to normal.
So I don't have this phone.. but does the xperia have an Odin flash mode? Or is it only fastboot?

Hi mate !
Your phone is not dead, I had the same problem with build5 kernel, and went back to build4 with my nandroid backup.
Take out the battery of the phone, put it again and then you should be able to enter fastboot mode.
Flash build4 kernel, is stable, and stick to build4 until build5 is fixed or another build comes out.
Hope it helps
How can I go into CWM recovery. The phone is not Switching on even after Reinserting the battery
succesfully managed to flash the build 4 kernel. The phone's been drained out and is charging now. Do I need to reinstall the ROm again or wont it be necessary.

Please tell me how you got into the fastboot mode.
I took off the battery, put it again and then tried tu turn on the phone without the usb connected, it vibrated but nothing.
Also tried to turn on with the usb cable connected, same thing.
U have to unlock Bootloader to get fastboot mode...either official way or unofficial way...

As soon as you took out your battery, you need to enter into fastboot mode.
I mean as soon as you have inserted your battery, press menu button and connect right away.
I also faced this prob for my neo too. You can also flash .ftf to your phone as soon as you have inserted your battery.
Same issue happened to my Xperia go. Cant enter CWM, fastboot, flash mode, or even power on the device. Cant charge also (i think). When plugging the charger either from wall charger or USB to pc, it just stays in red led then dies out again.
Take note: I cant reset, hard reset, or even power on the device.
What happened is that I flashed the wrong kernel on CWM. After the phone rebooted, it stayed on black screen. Cant turn it off. Until i guess the battery drained out. Now the above situation is happening.
Please help! Is it a choice to open up the phone and reconnect the embedded battery?
I prefer not to do so, if there is an option to fix it. The phone can't charge. Is there a way to force charge the phone without a working kernel?
Thanks in advance!
What's your issue??
Remove the battery and go in flashmode !
Flash stock fw ftf file via flashtool!
Voila,you have your phone back alive!

Oh...So your phone is xperia Go...
What kernel you have flash?I hope you didnt flash kernel for xperia Neo...if you do that,it might hard brick your phone....
Sorry for posting on this X-Neo section, but this is the only section that came near to my problem. I posted in XGO section and awaiting answers.
This is the first I got. Oh sorry, its not a kernel. I was updating CWM 5 to CWM touch 6 version. Did this in recovery. A flashable version of cwm.
I entered recovery, install from SD, the install completed, Then what I mentioned in my previous post happened. Not booting up. No vibration, no hard reset, no fastboot, no flashmode. Just the red led when plugged in to PC or wall socket.
I hope you can help me sort this one out

[Q] [q] xperia p wont power on !!

My Xperia P is not powering on.
Yesterday i was installing custom kernel on it. But I missed one important point in the flashing of the cyanogenmod kernel, and ended with a BOOT lOOP. So i removed the battery in order for not to wait for several hours to let the battery die.
Then i fastbooted the phone and flashed stock firmware using Flashtool. The only problem is that now it wont power on. No display. NO vibration. NO hard reset thing. NO soft reset. The device is not responding at all. If I connect it to the PC or wall outlet, red led comes, and after 5 mins or so, it goes off.
I thought i messed up with the kernel or so, so I with the help of rubber band trick, manged to get into flash mode, and re flashed the system with the stock rom.
But AGAIN IT WONT POWER On ! no matter how long i press the pOWer ON key, it wont respond. :crying:
what should i do now ?? please help me.. !
Used this !! n VIOLA ! phone booted ! if anyone else has the same problem I had, do this.
http://forum.xda-developers.com/showthread.php?t=2128581
There was no need to remove the battery.
Long press power + volume up until you feel (1+) 3 vibrations to turn the phone off.
The 1 vibration is a hard reset but it won't always happen.
Battery is probably fully drained. You shouldn't have removed it. Connect it to the wall charger for 2-3 hours.
Then
--+ redownload ftf from different source and try flashing again.
OR
--+ Download official flashtool from sony website and flash phone with that.
I prefer option 2 as it hardly ever fails.
DID YOU UNLOCK THE BOOTLOADER?

Battery is probably fully drained. You shouldn't have removed it. Connect it to the wall charger for 2-3 hours.
Then
--+ redownload ftf from different source and try flashing again.
OR
--+ Download official flashtool from sony website and flash phone with that.
I prefer option 2 as it hardly ever fails.

Well Hamzaa Murad, you were right. Battery was fully drained. Well, I left it to wall socket for over a night, but it didnt charged. Somehow, the Rubber Band trick worked and i was able to flash the phone using flashtool !
Ty for the suggestion. :good::laugh:

Xperia P wont boot and if cable is plugged and it doesnt even charge

Hello to all!!!
I have a problem with my XPERIA P(not rooted or unlocked), it wont boot if the cable is on the phone(pc or wall charger) and doesent even charge. When tryong to boot it shows only the SONY logo, not even xperia(which comes right after sony).
Tried getting into flash mode or fastboot mode, but it is the same thing.
If i switch on my phone with no cable plugged it starts normally.
When this happened i had no battery at all. After searching the web i found a guide to open my phone and remove the battery connector. After removing it and plugging back again it started charging. Now it wont charge anymore that way.
EDIT: Mac wont recognize it anymore(mac bridge, flashtool, adb)
Does anyone have an idea?
Thanks!

Try flashing the phone with stock ftf file via flash tool , you can find plenty of how to videos for that on internet . Your phone will be fine I guess
Search "Your phone model " "version" "stock ftf" download and flash it
Hit thanks if helped

The problem is my phone wont stay in flash mode. It shows up the green led just for a sec and then tries too boot up normaly(green led turns red and shows sony logo) then it shuts down again...
Same for fastboot mode (blue led for 1 sec then again red).
Any idea?
Thanx in advance
@aserreqi
The disconnection issue is driver related. Use windows 7/xp (friends computer) install flashtool and then install the driver pack located in it. Then flash stock ftf.
Before this charge your phone overnight.

I tried with windows 7(sus, flashtool, pc companion) and osx (sony bridge for mac and flashtool) with no results.
I will try again with windows if can get to charge it any more, because now it is not giving any sign of life
Thanx

I had similar kind of issue , phones doesnt stay in flash mode when it should but I managed to get into fastboot mode , IT DID STAY THERE for me and I flashed some other kernel to make it work for few mins as I only wanted flashmode to work which it did . Try charging your phone for 2 hours and grab any kernel which is said to be fine with your phone , either ways you only need flashmode to work. If fastboot is also disconecting even after you have charged your phone umm DRIVERS DRIVERS !
Make sure you have all the drivers installed I always use flashtool, nothing else to flash

I have charged my phone now for 3 hours. The only way i get to charge now is discharging the battery to 0. I have to put it on charge(wall charger) pull off the connector of the battery and then put it again on.
If the phone is a little charged and i turn it on it wont charge any more. No charger or pc works.
I tried again the procedure of getting into fastboot or flash mode, but still nothing happens.
Green or blue led for a sec then tries to boot again.
I forgot to mention that the phone works like normal when not in charge, it boots normally and everything works fine...
P.S. the drivers are installed. I installed them again and again.
Thanx for your help anyway!!

Oh my god , I feel bad for you . Try everything you could . Our last resort is to go to a sony service centre , TRUST ME THEY ARE DUMB AS HELL so you are better off knowing about roms and all , but still go to them if you cannot do ANYTHING . Good luck ,btw I dint understand PHONE WORKS NORMAL WHEN NOT IN CHARGE ? how is that possible

I hope u didnt fry your phone charging ic like i did on mine. Using fake charger and short hv burst suddenly turn my phone exactly like yours. I somehow managed to recover from it temporarily by shorting usb wire while charging it and eventually the phone die. Haha lol.

This is not the same problem.
First try volume up + power for about 15 seconds untill you feel (1+) 3 vibrations to turn it off.
Then try flashmode.
