Hi!
I got a xperia V, and the former owner told me tha it was flashed with a xperia Acro S firmware, and no longer turned on, so i tried to put it in flashmode with no success, then I tried a trick that saw over here (on a xperia sola) that was to connect usb without battery, an then put the battery as fast as possible, to my surprise this worked flawlessly, and I could flash the phone with flashtool and with Sony Update Service as well, the problem is that after flashing the phone still didn't power on, thinking it was the battery, I replaced with a new one, but still no success, The battery is not charging (according to my multimeter). May be the phone is not detecting the battery or the board is damaged? but is strange, because if that were the case I think the flashing would be impossible.
When I connect the phone to the charger one of two things happen:
1. Constant red light
2. Red light (if on a PC, I get the sound of a device connected), then red light goes off (if on a PC the device is disconnected), and then red the light comes back with a fading effect.
After some waiting the red light disappears and nothing else happens.
Any ideas on what I've been doing wrong, or what's wrong with the phone
EDIT:
Some more info, when the red light first appears, from lsusb the device get recognized as:
ID 0fce:d17b Sony Ericsson Mobile Communications AB

When the light disappears it doesn't get recognized at all.
Thanks.

Any luck finding a solution? i'm suffering from the same
Happened once for me also. Used to have red led lighting when I accidently cross-flashed a kernel which was meant for Xperia T. I simply access fastboot and flash stock kernel from my PC. If you are unable to access fastboot or flashmode, you are out of luck.
Hi guys! First of all, sorry for my english, its not my native language.
Yesterday my phone turned off because battery was too low. I put on charge for the whole night. Today when i waked up, i want to turn on my phone after disconnected from charge, but its wont turn on, just red light flash 3 times. I returned to charge but still cant turn on. Sometimes i got the sony logo, then i see the battery icon on screen, but still cant turn in. I have searched on the forums, and maybe its get bricked. I tried to connect the phone to pc, but sony companion and flashtool cant even recognize the device, but my pc see it as unknown device.
What can i do now?
Pls help guys! :crying:

It doesn't go to flashtool mode? If you have drivers properly installed, it should go to flashtool mode. Make sure drivers are ready and then connect USB cable to the phone and not to the PC. Hold down volume down and then connect to the PC. Green light should turn on. It means your phone is in flashtool mode. Flashtool will recognize it. Flash the ftf file. (If it is not happening, remove the back cover press power off button with pen or something until it vibrates three times. That will turn the phone off and then retry)
If you run into any sort of error, fee free to post here!
Happy flashing!
PS: If I helped you, press thanks!

Download Ubuntu latest version from ubuntu.com and make bootable usb(I use powerISO for making bootable USB). Rest will be simple. Do it. I'll tell you later. You'll have to edit a file and install JAVA and run flashtool. Simple and straight!
Dont make it hard...
Let it recharge for at least 24 hrs (comment from Sony)
After that try again..
@up: How do you think it will work on Linux when even Windows cant recognise the phone? Bit pointless if you ask me..
Thank you guys for helping, it seems just my charger is broken. I get another from my friend, and after a hour charge my phone started!
It seems everything okay now, i not need to flash or start a recovery, just need an another charger
Thank you guys for your help!

Actually, I was suggesting Linux because many users run into trouble while installing drivers on windows 8 or later. It was very simple on Ubuntu that's why I was suggesting it. And phone doesn't go to flashtool mode or fastboot mode unless proper drivers are installed.

Your problem has been discussed over and over again, meaning the answer to your question can be found using the search function.
Search for "bootloop".
I have simillar problem. I have CM11 installed for half a year now and everything was great. Yesterday my phone freezed and turn the screen off, after one minute it restared by itself and freezed again. After that it reboot by itself one more time freeze on the desktop and died forever.
hardreset on back side not working (i try to hold it down for 20 sec+ ). When i plug it in charger led turns red (i had it on charger for 8 hours and it is still red light and phone is dead).
PC companion cant connect to phone, flashtool can't connect, ubuntu can't connect. I will now connect it directly to PC and wait for few hours, but i am not sure if this will work. When the phone goes dead it was on charger with around 25% battery. Any idea what else to try?
Try an charger with more Ampere. I solved that problem charging with the ipad charger....
The best i can do is 1 Amp with car charger (from Plantronics, so i believe it is 1 amp). But still nothing after 1 hour
stronger charger i can't find. Any other idea? The phone is still dead. No vibrating, no detecting from PC only red led light when i start charging it. I am sure shutdown didn't happened because battery was empty, before it freezed it had 13% and then it was at 25% when it died (i was on call) that is why i know this.
My Xperia Z will not boot; the red LED flashes three times when I attempt to turn it on. I have tried resetting using the power button and volume up (most of the time it does not produce a response, but if it is plugged into my computer it will, where the LED will only turn off for maybe two seconds before coming back on), I have tried unplugging the battery (I have done this multiple times and on two occasions left it unplugged for over a week), I have tried flashing multiple different firmwares through Flashtool (they flash successfully but the phone still does not boot) and I have tried charging it for days and even a week one time with different chargers, but it still refuses to turn on.
This issue first occurred after I replaced the antenna flex cable and the buttons/microphone flex cable due to accidentally breaking them whilst replacing the LCD. I think this issue may have started because the battery was only on 7% when I disconnected it to replace the two parts, but I fail to see how this would discharge the battery so much? I am willing to purchase another battery if I can be certain that it will fix this issue.
Unlike some on this forum in other threads I have read through, the Sony logo does not come up at all, the screen is black the entire time. Also, when plugged into my Windows 8.1 laptop the computer tries to install drivers and says that it does not recognize the device "USB device not recognized" "The last USB device you connected to this computer malfunctioned, and Windows does not recognize it". When now attempting to put into flashmode connecting it to a USB 2.0 port the phone does not respond for five seconds, then the LED flashes green then red immediately after, before the LED goes off again, then the firmware is flashed (successfully). Attempting to put the phone into flashmode when connected to a USB 3.0 port will only result in the LED turning red.
Thanks for your time, this is really frustrating me, and any help would be greatly appreciated
Help please, anyone?
Sometime i wake up and my phone is turned off , when i try to turn it on it flashes 3 red lights , charging would make it turn on , so 3 red flashes is from battery and since you can successfully flash frimware than it is not bootloader problem , it is either battery or something else is destroyed inside your phone , first try another ftf

Thanks, I have tried two alternate ftf files with no luck, but I will try a third and see how that goes Yeah, it's okay if the current battery is faulty and buying a new one that will fix the problem, but I don't want to waste money if that isn't the problem
Do you have 12v car charger. Try to charge with it. Helped to wake up my phone last week after too much drain to the battery
My phone was not entering flashmode just before when I was trying to flash a different ftf file, so I wondered what would happen if I disconnected the battery, and then tried it. I first just connected the phone without the battery and got a solid blue light from the LED. Then when I tried entering flashmode without the battery connected it worked! So since I can successfully flash ftf files without the battery connected I'm assuming the issue is the battery, or could it possibly be the part of the motherboard which the battery connects to like this http://forum.xda-developers.com/xperia-z/help/hardware-fix-xperia-z-charging-booting-t2760911 ?

I do have one somewhere, but I think it's broken The issue must be related to the battery or battery connection now, so I need to figure out which of the two it is before I take any further steps to fix it?
So I ordered a replacement battery and when first connected the phone would not turn on. After charging for a little while the LED went red, and the phone now vibrates when I attempt to turn it on and also when I try to reset it. So the vibrations feel correct (it vibrates once when turning on, once when volume up and power have been held for five seconds, and three times when volume up and power for ten or so seconds), but it still refuses to boot. I have tried three different chargers for extended periods of time, disconnecting and reconnecting the battery multiple times and have flashed a different .ftf file, but all to no luck. My Windows 8.1 laptop computer still says that the USB device is not recognised and nothing seems to be progressing
Is there anything more that I can do from here to try to fix it? Anything would be so greatly appreciated
Bump :fingers-crossed:
Mainboard may be broken.
I had this problem after flashing a wrong recovery but the symptoms were the same. I sent it to a repair center and they changed my mainboard and it worked fine so it could be possible that you've broken your mainboard in a way. (The reparation bill was paid by the warranty *horray*)
I hope you can understand what I'm trying to say.
Off topic: yay, it snows!
Hi wonderful XDA forums, i'm an italian user, then sorry for my bad english.
I'm in a very strange situation, the new year starts strange for me.
Yesterday trying to short circuit the resistor to make the vibration works again( i read on internet and i see that works with other Xperia Z), the phone power down and won't boot anymore.
The strange things appears now, when i plug the usb cable for charge the phone, nothing appear, no LED, but if i disconnect the battery with the USB cable plugged-in the led blink red one time then blink a second time and become blue, and if i press volume down immediately afer the first led red blink, the led become green for 1 sec and the phone go in Download Mode.
When i use original Sony charger same situation, but when i disconnect the battery the led blink red 1 time and stays on and the phone shows SONY logo but immediately reboots go in a bootloop like this, red 1 time and stays on and the phone shows SONY logo but immediately reboots, i noticed that if i press power button several times after the SONY logo i can see the low battery icon but if stop to press the button the screen goes off and restart the bootloop describes upper.
I try several wall charger, and several cables oviusly the original SONY USB cable and wall charger, but nothing change, the battery is new and works because i test it with another phone.
Connecting to PC i can flash rom ftf with FlashTool without errors, but at the end of the process the phone won't boot, and won't charge same problems.
I noticed that the phone can't be recognise if the battery is connected, just when i disconnect the battery the phone go in fastboot mode or in download mode, for example when i flash a new ROM with flashtool when ask to connect the phone i must disconnect the battery and press volume down (in this way the PC recognise the phone, and the phone go in download mode) then i can connect or left disconnect the battery, anyway the flash operation would be OK but nothing change.
Sometimes when i connect the phone to PC the system ask me for QHSUBS_DLOAD drivers and sometimes the phone is recognised with SOMC FLASH....
I know this is a very bad situation, only Xperia Guru's can help me, but probably this phone is dead.
But I trust in XDA Community and i know that is the only place i can get serious and valid reply
Regards Samuel
this sounds exactly like what happened to me
This is extremely weird this happened on the same day... ?
Hi friends, welcome to soft brick world i think.. But i m happy and unhappy that i am not the only one in this weird situation..:silly:
"short circuit the resistor to make the vibration works again" thank god I didn't try it.. otherwise I'd end up with dead device
Help pls!!!!! Time ago my lt30p died, it charged but got stuck at the sony logo so my logic was to erase the firmware and reinstall it (but it didn't worked) i left it like that bc i had another phone so it didn't bothered me, but now i want to use it again.
Right now when i connect the phone to the wall (to charge it and get my dirty hands on the software) the red led comes on for a while, then it turns off and the green comes on, it tries to turn on but doesn't get past the Sony logo and reboots a few times until it looses power and the red light comes on again, and i don't think the battery is charging, when i disconnect it from the wall charger and try to turn on the phone it just gives me two red led blinks.
Does anyone knows what to do or has the right files? Im a noob in this kind of things but i am sure (kinda) about what im doing (kinda), i read that i don't need to unlock the bootloader for this and at this point i can't do it since i can't turn on the phone lol
Pls help me(( i don't like no more this grand prime
Nvm
I found the problem guys, flashtool 0.9.24 doesn't work forma lt30p, had to use 0.9.18 (for those that still use their Xperia t in 2018), but thanks for the post with the firmwares, ily
