Hey fellows,
I'm a brazillian, so my english is really, really bad.
I got an xperia z2, and after the exchange of the screen, it doesn't turn on, only shows the red led 3 times.
I've tried PC Companion, Flashtools, Emma, root programs, and nothing. Not of these solved my problems.
Can any good soul here help me? i'm kinda frustrated.
Thank you!
P.s.: Locked bootloader
Looks like you damaged something on motherboard during changing your screen. Is fastboot working?

Yeah, fastboot mode still working
well, when you replaced screen by yourself, you lose your warranty, so you can unlock bootloader and flash recovery (the best way is Cyanogen Recovery - TWRP doesn't boot on my phone) and flash CyanogenMod and then when it will boot, flash stock rom via flashtool or pre-rooted stock from recovery.
How can i unlock the bootloader?
i've tried to flash it, but didn't worked.
it shows the low battery screen when reboot via fastboot, but that's all.
That red light is the low battery advice... Try to let the phone charge turned off, with his original charger. If it charges, use flashtool later when phone is fully charged.
If don't charge while connected with his original charger, you have miss some hardware connection in the screen change.
Can you get in fastboot mode with the battery connected?

I had EXACTLY the same problem after I got my new LCD screen from China.
I was sure that I did not do anything wrong with changing the screen (no damage)
But please do as it says here, and it works again. Be careful, it is not that easy

So I upgraded to a custom ROM, everything appeared good.
I then did a factory reset via menu>settings. Phone didn't boot up past the Sony Ericsson splash screen.
So I rebooted it into recovery. Did another full wipe there. Still wouldn't boot past the splash screen.
It stayed on the splash screen for a few hours then is went off. Not it won't boot at all.
I can no longer get it to boot into recovery.
When I connect it to Flashtool nothing appears to happen except the red LED flashes twice quickly.
When I try to turn it on all that happens is the red LED flashes twice quickly.
When I plug it in after a couple minutes it boots to the Sony Ericsson splash screen, stays there for a while and then the screen goes off again.
What can I try? Any advice would be Great.

the red led flahes means it has very low charge left.
charge it for 1-2 hours and then try flashing stock firmware via flashtool.
If it doesnt work, then put the battery in other phone or external charger and charge it.
Then try to flash stock firmware.
Also, AFAIK you should not do a wipe from settings menu on a custom rom ( I might be wrong about this )

That's what I assumed, but it flashes red like that after being on the charger for 8 hours.
And the battery is not dead because I was getting multiday usage out of it last week.
But I will try what you suggested again. It is on the charger right now...

Honestly I'm not going to go out and buy another accessory for a phone that may or may not be dead (espesially since I would have to order it online).
Maybe I can find a friend that has a X10 though.

Same result as Flashtool. LED just flashes red.
OK I found someone that has an Xperia Play and it appears they both use the BST-41. I'm gonna see him tommorow. Hopefully with a fresh battery I can get it to boot into recovery...

RESOLVED.
I used another battery and tried to enter recovery. No luck,
So I had my friend charge my battery in his phone. Brought my phone home. Used Flashtool. Worked! Yay!
Thanks guys.

Hello.
I have rooted the xperia U using the flashtool by following a guide available on xda. Everything worked fine. I wanted to install a custom rom for which I had unlock my bootloader and flash a custom recovery for flashing the rom. I downloaded and flashed cwm. So I unlocked the bootloader using the official method, i flashed the boot.img of the custom rom(in fastboot) and tried to go to recovery, but my phone wouldn't switch ON now.
I was able to make it reach flashboot mode(green) and tried flashing ftf.. Even that's not working.
The service update software is not even detecting my phone.
Please help.:crying:
When you say, not switching on, can you feel it vibrate when you push the power button?
Also whats the error you receive on flashtool?
Yes, i do
But the screen is blank and I can only see the red notification light

May be you flashed wrong kernel, which is not for your phone.
Try to charge the phone for a few hours and after thats try flashmode again to flash stock rom...
same problem
Actually I am facing the same issue u had with your Sony xperia u. Please help.
Charge the battery, seems gone flat. Leave it on charge for half an hour or so. If that doesn't work maybe the software is corrupted to the point it doesn't cold boot to charge, so charge battery separately using external charger for half an hour or so. It should be able to boot at least to flash mode (Vol Down + Power).
hello everyone, When i insert my phone to wall charger i blinks the led and a red light flashes to beside the led light, but phones never boots up, cant access recovery and fastboot. Is this a hardware problem? i dont think so because my phone didnt fall i just restarted it and then it didn't boots up.
Any help regarding this will be appreciated.

No.
Just change your charger don't charge it with moto charger. Use a different good charger and leave your phone phone to charge for more than 6 hours.
Hopefully it will get switched ON.

I think their is something wrong with the ROM.
You have soft bricked your device.
Few months back I too soft bricked my device while on custom rom. But somehow I was able to go in recovery.
Just try to go in recovery mode or if it doesn't work then you have to sideload the rom.

Your device doesn't even show bootlogo since my device used too.
If it doesn't then you have hard bricked your device.
For sideloading just google it or search in forums but it won't work if you device is hard bricked.
I deleted my OS in TWRP recovery, I've tried doing many things but none of them have worked. I tried flashing a stock kernel using fastboot, flashtool, using sony's flashtool Emma but all of them gave an error. My bootloader was unlocked and i think USB debugging was on but i can't be completely certain. And I'm not sure if the phone is charging or not because it's just stuck on the sony logo.The model is D6503. I'm pretty new to this stuff so i don't know what to do, if you need any more information i'll try to provide it as fast as i can. Thanks in advance.
Do you still have access tp TWRP? If you do, just go into the recovery flash a custom rom from XDA then try to return to stock if you want.
Are you have done a flash thing before?

Yes I have used flashtool before. It gets stuck while flashing data and doesn't move on any further. I left it running at night and when i came back to it 10 hours later it was still stuck on the same step. Maybe it's a battery problem and it runs out during the procedure, but i can't check the batterly level because whenever i try to charge it i get the sony logo and it stays stuck like that. I tried the red button at the side next to the SD card slot but it just vibrates 3 times and then turns itself back on when i plug it back into the charger and gets stuck on the sony logo again.

My battery life is pretty bad overall it especially drains really fast after reaching 15-30%. Yes I can still connect to fastboot and flashmode. I've tried using both to flash a stock rom/kernel but both of them gave errors.
When I try to use flashtool it gets stuck at some point and doesn't go any further. When i try to flash using fastboot i get an unknown error within seconds and it doesnt work.

Strange... It can be the battery because if you can connect to flashmode/fastboot mode this means phone is still alive. I also had a battery isue too which didn't let me boot the phone at all. Anyway you should leave your phone on charge for overnight then try to flash something next day ornif you can someone open the backcover of your phone you can try to dissconect the battery and boot the phone while connected to charge but if you don't know how to open it please don't do it.

Hmm strange... I am sure that you can't get into flash mode without the battery. But I am kinda sure the problem is the battery becuase when my old battery died my phone just kept blinking on Sony XPERIA logo. Anyway I think you should get other's idea as well.
My device is not powering on because it shows that the battery level is low even though it's not.
A couple days ago my device just powered off without a prompt or anything. I was using my browser and all of a sudden it powered off. I tried to turn it on but got nothing. Then I connected it to the charger and the display showed the battery icon and the LED showed red. I tried powering on then but it wouldn't start. The Sony logo would come up and then go off again. This happened a couple times and I connected and disconnected it from the charger a couple times and after a moment it started normally. It happened again later but started back up after connecting it to a charger. The next day it happened again with the Sony logo showing and turning off again continuously and all the while the LED is red. Blinking red twice, showing the battery icon, then the Sony logo and turning off again. But now its not showing anything. I connect it to a charger which shows a red battery icon for a few seconds and then black screen but with red LED. I had LineageOS rom installed so I thought to flash stock ROM again which might solve the problem but now I can't get the device in flashmode to flash the ftf.
(IDK if this is relevant or no but a year and maybe half ago I had a problem with the battery. The phone took about 5-6 hrs of charging and discharged in 4-5 minutes. I went to the service centre and they told me it was a software problem which they fixed.)
Can anyone suggest on what to do? Any help will be appreciated.

this might seem irrelevant but trust it isn't, if you have the TA partition already backed up you should restore it, when you do your problem would be solved, I had same issues, and it turns out that the TA partition contains everything the phone should do to boot up, and what to do, its like a blueprint that the phone follows, I restored the phones TA partition and everything was fine again, flash advanced kernel TWRP via fastboot in flashtool, and instal a stock firmware from there and as soon as you can boot the phone in the system restore the TA partition and flash stock ROM via the Xperia Companion, Thats exactly how I solved my issue
