Hello, I cracked digitizer of my Xperia.
So I took it apart and wanted to fix it.
I heated, took LCD and digitizer off, tried to separate them nicely, but I'm pretty sure I made a little bit of damage to LCD.
Anyway, now I wanted to try phone without screen before ordering parts (you know, maybe I damaged motherboard or something... )
So... I plug all the cables, make everything back except digitizer is off now, but LCD is on.
I try to turn it on, it vibrates and that's it. Nothing more and after waiting over 10 minutes it still doesn't show any signs of life. Plugging USB cable from PC or ac does not show any signs. I can't do anything until I unplug battery and plug it back.
If I try to stick USB cable before turning it on, red led flashes brightly and that's it. What's even more interesting, if I unplug the cable, led keeps flashing and I have to unplug battery again.
I can see green led flash for a second when holding volume up and plugging to PC and blue led keeps for long time if I plug to PC while holding volume down.
So now you know my situation, does it have to be like that or no?
Maybe there's a back signal from LCD I mean if it's not connected, phone does not work or something.
Before everything phone was working perfectly.
Hope to hear some advice, thank you.

Its looks like a mo-bo issue for USB and LED issue. Check whether all connectors are in place.Also for digitizer issue i thing either the connector is not properly attached or the flex cable is damage.
Any more opinions?

I accidentally dropped my Nexus One when I was taking it out of my pocket.
Now, the touch screen or the charging port does not work
The screen turns on fine, and the trackball and power button work fine, but the screen isn't responsive at all.
In addition, the screen says that I have 0% battery left, even though I know I have well over 80% left.
I've tried to plug in a USB charger and it wouldn't recognize it at all. When I put it on the dock, however, it recognizes it, but still, there is no charging indicator.
Is the phone done for?
Thanks
With all those faults, maybe, but there might be hope. The digitizer connection and charging port internals are all based at the bottom of your phone and seeing that the power button still works then the bottom board is probably damaged. Try eBay for the parts. However if something has been physically damaged on the charging port then you'll have to make sure to change it too.
Update:
Phone is back to working state after numerous reboots and battery pulls.
Can anyone tell me why it was behaving this way?
Hey, Newbie here
So long story short, I water damaged my Xperia Z, bought a second hand one with a cracked screen and switched the main board into the water damaged phone.
Now the problem is that the charging light comes on when it's on charge but it's a dull red. When I take the phone off the charger the LED stays on. I've tried the Down+power button reset but it only makes the light blink a few times. I tried connecting it to PC companion but the computer won't read the device but the LED turns bright and the computer indicates there's a device attached (for about a second then disappears) which isn't recognizable.
I'm all out of ideas. What is the problem and what can I try to fix it?
Thanks

Sorry I meant up instead of down haha
dull red charging light mean the battery is really dry..try connect your charger until the light change, sometime it takes several hour for the battery to get charge again after it been dry for too long..also why you don't change the battery altogether with your motherboard? maybe your original battery still functional...
hi,
sorry for my bad English,
I bought Xperia With a damaged touch. The phone is normally turn on. the touch did not work. I decided to take himself for the replacement of touch (glued to the LCD). I disassembly phone . before removing the motherboard still plugged in the battery to see if the battery will not hurt the dismantling of the display, the phone is turned saw the Sony logo and disconnected the battery (do not know if it was a good idea). After removing all nicely warmed the screen and slowly removing pieces touch. Unfortunately, at the end it turned out that a little too much it warmed, because the screen began to appear discolored, so were pissed, I ordered a new display and in the meantime, as I wait for the touch I wanted to see if it works. I have connected to the display board, tape, buttons and battery. Turned on, the phone vibrated and enough black screen. So I stitched it to "poop" and I wanted to run, but it was all the same. Computer can not detect, etc.. After some time, as it was plugged into usb turn on the red light. Ive loaded software program SUS, and after you press the power button flashing red LED 3 times. I left the phone on the charger overnight from nokia (1200mA), but it does not improve, after that, that when you try to turn the vibration and again, so much. The phone is detected in fastboot mode (blue LED) and flash (theoretically green), because as I press the phone turned off and hold down my Vol- is a second red LED will flash immediately changes to green and then turns off the computer recognizes the phone as SOMC Flash Device (SEMC not SOMC) and in this mode for the update service is normally upload the software to the end, in the Flashtool the same situation. I do not know if it's important, but after every uploading the software when you try to turn this unfortunate flashes red LED 3 times as if the battery is discharged. Could this be a defective battery? Phone before you got in my hands was lying unused for some time. How it got it it plugged into the car charger (840mA) for around 40min +/- and normally work. I do not remember whether if it was on some LED.
Why could you buy a Xperia Z with damaged touch? And why you try to repair it yourself?

If battery was working properly before the experiment that you did there must be something wrong that you must have did.
Try a different battery and see whether it solves issue or else you must have damage the mo-bo
My Xperia dead after remove battery.
Stuck in flash mode.
Fastboot and flash mode works. (Blue and green led)
unbrick from flashtool?
Hi
I’m wondering if anybody has any advice regarding my problem. I have looked here and tried what has been suggested.
My stock, never rooted, never flashed, Xperia T (think it was Android 4.3 but can’t now check, the latest Sony rolled out) was working fine until yesterday. I was on a plane and noticed it had 20% battery life left so I plugged it into the onboard USB port. The problem is I think I hay have plugged the cable into the port the work way round – not the connection on the phone, but the actual USB socket. This should be impossible but somebody obviously had broken the port and it turned out the cable could be plugged in both ways! (I don’t know if it was plugged in the wrong way round but is the only thing that could possible explain the sudden death.)
Could this have bricked it? I suddenly couldn’t get a red light to show charging and holding down power on and volume up or down does nothing. I tried charging overnight via a wall socket when I got home but the result is still the same. Just a black screen and no sign of life. I have also tried plugging it into a computer with Sony’s PC Companion but as the phone is not ‘on’, it can’t be found.
Does anybody have any advice where to go from here? I’m more concerned about some recent data from holiday on the phone than the actual handset itself. If the phone is dead, is there any way to read the internal memory?
Thanks
Try this: Unplug the charger, press the power button. The phone won’t power up because there is no charge left in the battery. But press the power button along and while doing so, connect the charger without releasing the button. Now, you will probably see the red light. Please don’t take off your finger from the power button for around 1 to 2 minutes when the red light for charging will glow continuously. If you feel tired holding it, you can try sticking a tape on it in it’s pressed mode. Once you are sure that the phone is now charging the battery again(red light keeps glowing even after the power button is released) kindly wait for 5 to 10 minutes or may be more before you press the power button again to power the phone up. Now the phone will be up and running
If that doesnt work maybe ur battery is dead or usb port broken
Thanks for the advice. I gave that a go after trying a 24h wall charge and not touching it (which did nothing).
So, I held the power down, plugged it in but nothing. I held it down for around 5 minutes both manually and then repeated the process using the rubber band trick to keep the button held down but no red light ever came on. I think I’m going to try a new battery as I genuinely see that I have nothing to lose as I doubt it will be possible for anybody to recovery data given as the phone can’t be switched on so if I break it further I’m in no worse position!
Thanks again for trying to help though!:good:
When I got my xperia t it was in described condition. I also tried everything (rubberband trick and so on) but the only thing working was to open it and pull and put in again the plug of the battery. After that it booted immediately and I got this sleep-of-death-thing nearly every day... Since I soldered the battery as described in this Topic it happens only ~once a week. Good luck!
SOLVED! In preparation for the new battery arriving, I decided to take the back cover off. I unhooked the top battery connector and decided to connect it back up again, just to see if it did anything. Plugged in the charger and a red light came on straight away! I let it charge for a good couple of hours and switched it on – not as easy without the case attached – and it worked. I’m so frustrated with it being such a simple issue as needing to disconnect the battery but even more frustrated with the design that it is meant to be a ‘sealed’ unit with a non-removable battery. I used to often need to disconnect my old Omnia II battery to restart it but that was a simple case of cover off, remove battery, replace battery , put cover back on, not the creaky, back cover fear of cracking exercise of yesterday. Still it’s working now and hopefully life in the old phone yet!

Nice to see that bro!
Hey all,
I recently got an Xperia X Performance that was sold to me as faulty.
At first I thought it was the battery as it wouldn't charge (No LED) and holding Vol + Power did nothing.
I got a new battery, installed it and won't turn on.
When I plug it into the AC Adapter, no LED comes on.
If I hold Vol+ Power it vibrates once, then 3 times and depending on how long I hold it for (Could be 10 seconds, could be a minute) it might do that cycle again.
If I let go at a certain point I have able to:
Have a Red LED constantly on, even when the USB is not connected.
Have a Green LED constantly on, also when the USB is not connected. (PC Won't recognize either)
And the Sony Logo flashes up on a white screen for a split second and turns off and then it's dead again.
Note: The phones motherboard does get warm when I have one of the LEDs on. So something is going on.
I tried using the Xperia Companion to repair it (Like I did with many Z phones back in the day when they did similar things and that always worked) - this one doesn't work at all. PC Doesn't detect it.
Tried on a Win 7 and Win 10 system, both no avail.
When I took the back cover off the phone, someone has used, what I thought to be super glue to seal it shut.
And the OG battery was loose inside the phone before I replaced it.
So I am thinking, either it's bricked or just completely dead.
Have yet to check with a multimeter on the USB port but I believe it is working.
If anyone has any suggestions, or maybe some sort of help - I have only seen this issue with the older Xperia Z phones. Help is needed!
Thanks heaps!

There is no method to fix it, unless change the motherboard. I had also meet this problem, maybe you can try setool.
