Hi guys, yesterday I unlocked and rooted my Xperia U, as I didnt have time anymore, I decided to install the kernel today, so when I installed it, I tried turning on my phone - nothing. I just got that red light thingy sometimes that is active 2-3 seconds, I tried charging but still nothing, funny thing is, when I connect it to my 2nd PC with XP on it, it connects, but in My Computer I only see "Digital Camera" and cant open it, also Windows Explorer popup for it keeps constantly, well, popping up but its empty and I cant select anything. I'm now downloading flashtool, is there anything I can do else? Im desperate, I got this phone for only 3 days.
Okay, now I'm in flashtool, I'm about to start flashing but I cant get into fastboot mode... What should I do?
Bump? :crying:
Please dont make me spam, I searched everything, I'm pretty sure my problem is unique, I cant access fastboot. Nothing
try this:
1. charge your phone for about 1 hour
2. open flashtool then click fastmode and choose your firmware.
3. make sure your phone is off ( i dont know if this is the same with xperia U volume up+power button wait til vibrates three times)
4. when it says connect your phone into fastmode, connect your phone via usb, then hold volume up + power button and wait till it vibrates three times, then hold power button+ volume down.
5. it will flash your firmware.
or you can flash the stock kernel (just extract from ftf, same instructions above).
I charged it for the whole night, the problem is, I cant access fastboot. All the drivers are installed but nothing.
I'm sending my phone for repair probably, with rooting I broke my warrant, what's going to happen?

Ok fast boot doesn't work,how about Flashboot?

Nope, can't access that either.
Ok does your phone vibrates when you turn it on?Do you have any LED light?Does it respobd to anything?
Sent from my LT26i using xda premium
Not vibrating, also, no led.
The only sign I get is when I take out the battery and put it back in, it vibrates for a second. Thats it.
Try to remove the battery and than try all keys combination,and also try to get to connect it to your flashtool.Try hard reset combination.Remove the battery,put the battery,hold power+vol. up button for. 20 sec. If that doesn't make.Try the same only with vol. down button .If that doesn't work,take it to the service shop than....
Hit Thaks if I helped
Hold vol up when replacing the battery, then quickly shove the USB cable in. Phone should vibrate when you put the battery in and you have a second or two to get it into fastboot or flashboot.
Probably a bad install of a kernel, make sure you're using the right one for your phone.
Not sure if it works for the U, but that's how I fixed my Sola.

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?

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.

Xperia S Issues. Bad Flash
Hi, I read the 'existing users' installation instructions on the Sspeed ICS rom and installed the rom without installing the ics rom and kernel (I was tired). When booting, I go in a bootloop with the doomkernel screen. I can access recovery fine.
When holding vol+ and connecting to PC the phone goes back into it's bootloop and does not boot into fastboot.
When holding vol- and connecting to PC the phone flashes the green led and then boots into bootloop.
If I wait until the phone vibrates and lights up blue I can press the button to access recovery. I thought I could then just copy a gb rom over using USB mount but it is not detected on the PC.
Any help would be greatly appreciated.
Thank you

Glad I'm not the only stupid one on here
im not the expert here but I have bricked other phones before but never an xperia phone before. I have been reading up, the doom kernel has some mounting options, try to mount the sd card as mass storage so pc can send files accross to the phone. It should be mount and storage menu -> mount usb storage, then leave it on that menu and connect to computer, see if that works

Hi is this by the mount USB storage optuon ? I tried that and it wasn't detected on the PC. I could try another PC later. Recovery went into mount mode fine but nothing happened on the PC. Not even a blank drive which I know some people have had
If it blinks the LED for a second and reboots, that means that you don't have the drivers. Install drivers that are bundled with flashtool and try again. Or use Linux / OSX.

Just Press VolUp and Power button until you get (one vibration followed by 3 consecutive vibrations) ... it will mean phone is shutdown.
Once shutted down, you will be able to press VolDown while plugging phone to PC and it will enter into flashmode.
Then you will be able to flash a FTF using flashtool
doesn't work...after the 3 beeps i let go and the screen turns black but then the boot loop happens again, i cant turn the phone off

Hello. I've got familiar problem. My phone blacked out after one day having about 35 % battery full. I was trying to reset it by holding power and volume up buttons - nothing happened. Just once showed up Sony logo but then again black nothing. Then it vibrate 3 times quickly and from that time it is shutted down, won't turn on even in flashmode. LED is not working too. I was asking for advice in local store servise and guy told me, that new phones have to be at least 30 min on the charger. So it's here now for hour, no result. :/
Just fixed this issue.
Follow these steps
1.hold vol up + power until phone vibrates 3 times.
2.open flash tool and point towards your stock file.
3.hit okay
4.wait for flash tool to prepare the files then it will prompt you to connect device in flash mode( vol down + power)
5.wait for it to finish. Unplug reboot and there you go fixed...
Hope this helps

Use the bundled wallcharger!!! not a PC, pc has too less power to charge it now!
After wallcharger is placed hold vol+ and power for a few seconds until 3 vibrations, then let the phone on charger for atleast 2 hours, if all is good phone will bootup to the "charging animation"

Something similar happened to me. I have the bugged version of chargemon (only can charge with phone on) and accidentally discharged completely. The phone didn't boot, didn't charge and didn't do the 3 vibrations thing. So I put the battery off, conected the wall charger, putted the battery and it booted
It's really easy to remove the battery, you just need to be careful
Guys, i was upgrading the ROM but this time i used this software, UNIFLASH , it showed some cmd windows, later phone automatically booted to cwm, and then turned off! since then its not turning on neither blinking any LED! guys, please show me a ray , help me! phone is not getting recognized by flashtool either :'( and same with seus

guys, phone is not able to boot in any mode, it be fastboot or flashmode! its completely dead thats what i meant earlier. After a lot of researching the whole night, i was able to figure out that the bootloader is that the UNIFLASH corrupted the bootloader. So how to fix that?
try this: make sure you have enough charge and the drivers of your phone are installed correctly. (flashtool drivers)
power+volume up wait till vibrates three times,
then connect your phone to pc.
run the flashtool and prepare the firmwares youre going to flash,
a screen will appear and says turn off your phone....etc
hold power button + volume up wait till vibrates three times
then quickly hold power button + volume down.
it will flash the firmware.
just keep on trying.

PCC also didn't detect my device,
please help me to revive my sola ???
Hi,
Did you try to root your phone using the adb restore method? If so then you screwed your phone because this method is for ICS, not for GB.
Try this:
Shut down completely your phone (in case you haven't already). To do that you must press and hold volume up and power button until the phone vibrates 3 times (approximately 5 sec).
Then check if you can enter fastboot or flashmode by pressing the appropriate volume button along with the power button. You should see a green or purple led.
If so then use SEUS (not PCC) or flashtool and flash the ICS firmware.
Then root your phone with bin4ry's method. There are a lot of threads to help you on that, use search.
If the above method wont work then you probably need to go to a service center to unbrick your phone.
Hope that helps

if you know someone with a sola use there phone to charge your battery
and taking out the battery shuts the phone down quite effectively so..
This may or may not help...
but this once happened with a previous Xperia phone of mine. I left it plugged into the wall for several hours (trying to turn it on repeatedly killed the battery I suspect) and then tried, I got the LED, from there you can use flashtool. Please try this. Also Sony Update Service? Repair option.
Plugging into the wall so long and see. Seems battery is the first you must get through.
GB with locked bl cannot be rooted.

@ Junior Member - OP
do your sola repaired?
if so, how you repair it?
While updating a new Xperia U to ICS the PCC had an error while flashing the new firmware. Now the screen lights up, the sony logo is shown for ~3-5 seconds and then it reboots.
After that I have been unable to get it recognized again by either PCC/SUS or flash tool.
I also checked my log files in Linux and no device appears.
I've tried 3 different machines (2x Windows 8, 1x Win 7), multiple USB ports. Also leaving the battery out for ~30 mins didn't change the behavior.
The green light for download mode comes on, but after about 5 seconds the light goes out and it goes into the boot loop again.
So by now I believe the device needs to be sent in, but maybe some one has a few more things I can try.
Try pressing the volume down plus volume up plus power button all 3 simultaneously till u feel 3 vibrations

Can you make sure the Flashtool drivers are installed ? Go to Flashtool Directory, open drivers directory and start the setup.. Make sure to select the Flashmode and Fastboot drivers are also selected. Then, reboot System and folow this order.
Startt flashtool,select f/w, wait for Flashtool to tell you to connect to device. Then, holding the Volume down button (while phone is switched off), plug the cable into phone (The usb cable must already be connected to PC before starting the Flash Procedure )
The Order is very important.. I had same issue with U (althoguh mine crashed with Flashtool and same as what you observed. When I followed this order, I was able to get it detected and flashed )
Hopefully, you wont need to return to Service Center
let me know how it goes
Cheers ! & Merry Christmas

No response, I've tried holding all three buttons for a minute, but it doesn't vibrate after turning on. The only way I can turn it off is by removing the battery.

I tried that right now, Flashmode and Fastboot drivers are installed. Flash tool is ready, device is plugged in with volume down pressed, green light comes on. Nothing is found on the PC, after about 5 seconds the green light turns off and the phone shows the sony logo. Green light also comes on if i simply plug in the usb without volume down pressed. So I'm thinking, the download mode has some how been corrupted?

Sorry about that, maybe a moderator can move my topic to the right section.
Are u connecting it properly???
Make sure when u connect ur cell to ur pc u have nt presed the power key
keep the phone off
Press the volume down button ( keep it pressed, dun
leave it) and connect it to the usb
U will see green light
Darn.. That looks bad.. That did it for me on every occasion. I think you might have a hardbrick due to the interrupted write cycle so I dont think any other way except to take it to Service Center
Sorry I couldnt help

Exactly what I'm doing and the green light does come on. Except it decides to go into a boot loop after it apperantly boots into download mode but doesn't stay there.

That's what I've been fearing. In which case it goes back to the seller in the hope that he will send me a new device.

Is there any chance of properly reactivating flashmode by using a JTAG?

Have you manage to recover your phone without taking it to service?
I'm in the exactly same situation... Any help is welcome...
While trying to enter flashmode, green light turns on but after some secs it turns off and sony logo appears on screen. any chance to recover this beautiful brick ?
thanks
After several tries (a lot of...) I manage to enter flashmode and SUS is now reinstalling sony ROM.
Honestly I don´t know how it works this time and not the others but i'm happy with it independently of what happens.
... seems flashtool is detecting ur phone try to flash first the stock kernel and do not wipe everything it shud be in timing though.. onces it is flash charge ur phone in kernel mode (phone is off) then you can flash the stock fw of ur XU.
I bricked my phone
I bricked my xperia U as well... When i tried to power ON, it just vibrates and nothing happens, i dont even get the sony logo. When i get into flash boot mode it gets connected but after 20secs, the phone turns off again. Only fastboot mode stays on. How can i unbrick my phone??? Plz help. I made a mistake by flashing the custom jelly bean rom without flashing the kernel first.

No worries. The phone turns off because it doesn't receive any signal from the PC - many people make the mistake of connecting the device in flashmode first, and then they start the flashtool etc.
Instead, load the flashtool first, go to flashmode, select a complete/full stock ftf for your phone (whichever version you want, but do double check if the ftf has kernel.sin file in it) and press the flash button. Only once you get the pop up with the animation telling you to connect the phone in flash mode, connect the phone in flashmode (volume - button pressed when connecting cable). As soon as you connect the phone, the flashtool will start its magic and your phone won't turn off.
if you can go in cwm wipe system then you will only be stuck on sony logo then use this guide http://www.youtube.com/watch?v=hPPWRXcsz7g.....it will work because this same happened to me and i fixed it with this method!
