http://i.imgur.com/eYhCtMr.jpg?1There are many people that changed their LCD (Z, Z2 ,Z3) and then were unable to startup the phone.
Of course one might think, is the display broken, did I mess it up myself, etc etc...
Here are the symptoms. If you have the same symptoms, then this will fix your Z2!
- the phone does not boot. Black screen. Will not do anything else then 3 blinks when you press the power on
- without battery, and cable in a charger (not in computer!), will show a battery logo on the LCD
- with battery in the phone and cable in a charger (not in computer!), will make the "Im charging the battery"-light burn red and after a number of seconds (but not always?) a bit dimmed red.
- the phone vibrates if you do the trick with holding the on button and the volume button and keep them pressed (without battery), but nothing more will happen.
- adb does not recognise the phone at all. Fastboot does, but ONLY without battery
- the battery is fully charged, and NOT the problem
- you can flash, unlock the bootloader etc, but only without the battery
- changing the battery with a new one, does not solve the problem.
You have all that? Great..
- open the back of the phone (probably still open )
- take the battery out and concentrate on the part where the battery connector is.
- take a deep breath and keep calm
- solder a very tiny, thin cable from one part to the other (look at the picture).
If the picture is not clear enough, just ask, and I will answer as soon as I can.

All thanks goes to Ahmed Koukou from Egypt who uploaded the solution on another forum, but without any tips and without description.
Registered specially to thank you and to confirm that it worked for me!!!
I bought a new display of Ebay. At first, I thought that it was a bad display, until I read that others had the same problem.
Thank you! My Z2 is alive again :good::good::good::good::good::good:
Hmm interesting,

- with battery in the phone and cable in a charger (not in computer!), will make the "Im charging the battery"-light burn red and after a number of seconds (but not always?) a bit dimmed red.
Always a bright red led
- the phone vibrates if you do the trick with holding the on button and the volume button and keep them pressed (without battery), but nothing more will happen.
No vibration, even tried the elastic band trick
- adb does not recognise the phone at all. Fastboot does, but ONLY without battery
If only if the PC would recognise something connected. so no adb
- the battery is fully charged, and NOT the problem
- you can flash, unlock the bootloader etc, but only without the battery
- changing the battery with a new one, does not solve the problem.

Good luck! Hope you will find a way to get the Z2 to work again!
Well i tried this trick and it worked however today after many months the phone just will no longer charge. The battery is in good condition etc but the charge is just too slow to give it enough power.
I cannot work out why it does not charge at full speed any more
My Z2 has been lying dead in a drawer for over a year now. I thought it was gone for good so I thought what the hell it can't get worse than it is so I gave this a try and it ****ing worked!!
I registered just to say Thanks. My Z2 is alive again :good::good:
it works!
It works. thank you so much. I was so attached to my z2 that I bought an original sony screen for replacement. Imagine the deception with these blinking lights. I would like to know why this needs to be done? anyone?
Hello,
after reading your solution I tried to get a very tiny cable for connecting the two points. I didn't have enough patience getting it working.
After trying it without success, I remembered in past, I had to modify AMD CPUs to overclock them. There I used a simple pencil making a line to connect them.
I didn't think long about that, then simply tried it, and had luck with it. My Z2 is now booting again! I'm happy with my solution!
Hope this will help some other people, who also don't have enough patience.

Million thanks, it worked. I had the phone broken for years and this fixed it. Though it was hard to solder.
Thank you
Just wanted to say thank you for this solution.
I had a similar issue when I put a new battery in it wouldn't turn on. I had the three blinking red lights.
No I have done this it works.
I used Car Window Demister Repair Solution liquid and it work just as well. Got a little puff of smoke but appears to be working okay now.
Again thank you for your help.
you are genius...totally work
Hello everyone. I am also desperate and I came across this solution. I bought the soldering tools however I was unable to do it so I wanted to ask you more about the process. What wire did you use to connect two points? I have 0.8mm soldering wire and it seems to be too fat for this. Also, the guy mention that he did it with pencil. How?
Thanks in advance
It helped me too. Was Xperia Z2, worked well before display replacement, battery at 3,95V, despite of it three red blinks when attempting to start, glowing red while on DC, but not charging (power consumption 0,133A though). Sometimes three vibras when attempting to Power+VolUp while on DC. Black screen only, no logo no nothing.

Hi there,
I have a special question to my G4 witch i do not get in operation anymore: The Problem is, that the device does not turn on, independent any keys. Either the ON-Button, Soft-Reset, Hard-Reset i do not get any of the "normal" screens. The display does not light.
Additional, the red power-charge-LED does not light when i plug in the USB-poer-supply. The same, if i disassemble the battery and plug the G4 to the power-supply...
The device has not been used for a couple of months. The last action a Upgrade to WM6.5 that worked definitively fine for a while.
Has anybody an idea? Or happend before?
Thanks in advance
Ernie
i think it`s easy
hey .. i doubt you have a problem with your g4 phone, i think you have a problem with the battery. since you left the batter inside the phone for alot of months and you didn`t use it, i think the battery is super dead, so dead, that the g4 cant power off and go to charge mode. 1 : you could try letting it charge more, like .. 1 hr plugged in , orrr , you could find an universal charger, which charges the battery by touching it`s + and - with it`s pins and putting electricity in it. (sorry for the bad explanation but i`m from romania). I think one of them two should work, if you know some other friend who has a working g4 just try with his battery. Good luck ! ^_^
Thanks for your reply.
But it happens without (!) the battery: If disassemble the battery and connect afterwards the power cable, the red LED does not flash, and no key has a function. As Soft-Reset "switch" and Hard-Reset (2-button on the left plus Soft-Reset-Switch)
First i mentioned the same as you thought...
Has anybody an idea what can be done here?
Thanks in advance.
Ernie
I'm encountering this same problem. I let the device charge over night with no luck. It will not power on at all. The battery was working fine last week. its completely dead
My Universal turn on the red LED for a seconds and after that do not charge and do not turn on. Have you find any solutions?
Thanks
exactly the same problem here on touch 3g
i got my touch 3g in Jan 2009 in Shanghai,China. Now i'm in singapore.... it's bricked, i didn't do anything wrong, it's not dropped on the ground or into the water, yesterday it was fine, but this morning i just found that it's power off. plugging in the power cable , and i won't see the orange power led. it's completely dead, soft reset and hard reset can not be initiated, because it refuses to power on.
i'm going to htc care center at harbourFront next weekend ...

You’re in the wrong section this is the Wizard forum.
I use a universal charger. Its one which takes the battery not one which plugs into the phone ...
whenever I let my phone run flat I leave the battery in the charger for a couple of hours then put it back in the phone and connect the phone charger. Once there are enough electrons whizzing around in the battery there's enough power to drive the IC that manages the charging in the phone ...
if the battery is too flat it won't even open the gates for you ...
Hi. The phone application was not functioning well and the F/C dialog showed up. I powered off the phone and from that point, the phone won't turn on.
The battery was fully charged before this happened.
When I press the power button, the phone vibrates for half a second, the screen brightens up but does not show anything but a black screen.
I removed SIM and SD cards, removed the battery and performed the above steps but nothing happened.
I also tried to put on the charger to see what's going on. Once I plug the charger, the phone's screen brightens but shows only blank (even without pressing the power button)
When connected to the charger, the green light for charging is on for some minutes, then goes off automatically.
I tried to connect it to the PC, and PC Companion finds the device as usually. It even shows the dialog on the pc screen to mount the device.
I tried a hard reset, but does not work
On some point, the sony logo appeared and then a dialog saying: "sorry process system is not responding". The first time I pressed Force Close and the phone turned off. Immediately after that, the phone turned on and showed the exact message. I pressed "Wait" but nothing happened in the next 15 minutes.
I called Sony's support center and they suggested a software update. Did the process exactly as it should, but again, even after the software update the screen shows nothing but black. It is all the time brightened for some reason.
I tried to turn off the phone for some time by removing the battery, but as soon as I put the battery back on, the phone's screen brightens and stays that way forever.
The phone was functioning perfectly up until this issue. The only application I had installed apart from some games, was AWDLauncher. On the screen I had only a TASK widget and a battery status widget.
The phone is 3 months old and has been always in perfect condition.
ANY help would be appreciated!!!!
Many Thanks

I tried the steps found in the link you gave me, but I couldn't go any further after step no (5) from the tutorial, as it would require to enable Debugging mode and I cannot access the OS (since the device won't turn on).
Is there a way to format all the contents of the device and have them replaced by running SEUS (as it always says that my device is up to date now)?
Was it this:

That Sony Ericsson told you to do?
If not, use that.
Download it, follow the steps when it says you have the latest version, press "Install Anyway".
Hope this works.
Hi itTim. thanks for the response
this is what i did but no improvement at all ((
Sounds like you broke your LCD screen somehow.
That would suck because I broke mine and it cost me $200 to fix.
Hi Hypercore.
Yes that could be the problem. The thing is that I always took rally good care of the phone, always carried in a leather pouch and never droped it. How sensitive is this lcd anyway?? Did you notice any cracks on your lcd or was the problem simillar to mine?
Thanks
When you turn on the phone does the lcd backlight turn on?
If so, look for any faint lines of color (usually a hairline size). If you see any of those then your screen is cracked.
the backlight is on, but there are no lines of colour on the lcd screen.
another weird thing is that the green light on the top blinks one or two times every time i put on the battery. even if the phone is off, once I insert the battery turns on automatically after a couple of seconds.
If all else fails you could try to flash back to your original fw with the tools here:

I had almost the same issue. Nothing worked. But, when I removed the battery and left it for a day (24h) without it, it just started working again. Still working without issues..
Good luck!

Phones are very wierd pieces of technology. I once bricked my k610i and that's a phone that's supposed to be impossible to un-brick, but out of nowhere a month or so later i picked it up, hit power and it turned on perfectly. Made no sense at all, but it worked.
Taking the battery out for a long time probably took all the electrical charges from it (kind of like how a computer power supply / monitor can hold power charges) and reset your handset.

if you have done this and did not worked , then it is the LCD.
send it to workshop and check it there.
Guys i Really need the solve of this problem , my xperia has blank screen now without backlight and the phone completely doesn't work . when i put the battery and prees the switch botton it gives me 3 red signals , i've updated and hard reset but it didn't work , and btw the LCD is fine , any idea. did removing the battery worked???? . please answer
After a looooot of time since my latest post, finally my Xperia came back to life. There was a battery failure which means the phone was ok all the time. Weird thing is that the led light showed that the battery was charging ok. I removed the battery and after a lot of time it is working ok again. This was really really odd.
FYI for anyone else that gets this issue.
I just had this for the past hour after trying to change my baseband....could not get it back for anything.
What I did finally try was run another baseband via flash tool, connected to usb and it started flashing....after flash phone powered on again...yeah I agree with everyone, that is freaking scary when it happens.
Hello!
I purchased this device some time ago and did not modify it in anyway (no rooting/flashing etc), just a stock device. After leaving it just laying around for about a month I tried to turn it on again and nothing happened. Connecting it to USB or wall charger just makes the power button red led blink intermediately.
Ive tried:
Reset button
Hard reset (vol up+vol down+power button)
Leaving it to charge overnight from the wall charger
Leaving it to charge overnight from USB
Singing to it
Specifics:
Stock firmware
Viewsonic VPAD7
Model#: VS13761
Any help would be appreciated (even as mundane as saying "its hardware is fried") etc, just want some clarify on what happened if their is no way to fix it.
Thank you in advance
Same problem
Even My Vpad 7 is having the same problem.
Can anyone shed light to the above problem?
Puia
Let's start with here -
http://forum.xda-developers.com/showthread.php?t=1015005 - post #6
Can you hold the "Volumn" Down button while pressing the Power button to get into FTM mode (diagnostic screen) - make a note of the basic information it displayed.
To exit/reset - you might need to use a small pin to press the Reset button at the lower bottom (left) of the device to get it to reboot.
If it does not reboot, power down or shut-off, does it stay on with only the RED LED flashing.
Probably the battery is dead or dying..
i am in a similar situation.. i can only see a Red flashing LED. the tab wont reboot, go into diagnostics or respond to any plethora of button press combinations..
For those of you reporting problems with your Vpad7 - apparently not responding & only flashing red LED, can you access/read/verify your device's FTM status? Does it show any sort of boot-up sequence at all (the 3 birds being the common one for official Viewsonic Vpad 7's?
Please re-check your mSD card - you have one inserted right? properly formatted and not corrupted, readable as a USB drive when taken out & connected to a PC? Try removing any Sim card or vice versa, insert one and try to boot it up? Has the battery being charged to 100% (using the stock 2.0A charger - typically take 4 to 8 hours)?
Since it's NOT rooted and has no custom recovery installed (right !) - even a successful effort to boot into Recovery Mode won't help at all, but, it will help if you can get into bootloader mode.
Still following ... if everything checked out up to now, it's very likely that your ROM was corrupted/damaged and you need to reflash the "correct" factory ROM (RUU or *.nb0 file) using the factory utility - as discussed in the referenced link .
If you think you know what you are doing and dare to try a DIY rescue by flashing it all over (got nothing to lose anyway, it's a brick - paperweight at this point) - see if you can access the viewsonic website and download the files directly ... if you cannot download/access the files, please post here or PM for possible alternatives from my private collection now in cloud storage (it's geared mostly for newer/ITE devices, however, but not all of it) Please be specfic with your model's firmware/build & other info as shown under FTM or see your factory carton's box for the technical info.
If it's under warranty, by all means, contact support & get RMA to return it for repair/exchange - in 2 to 3 weeks (4 ?) you will have it back in working order, good as new - no fuzz, no worries & the "brick" can fly in android again.
If none of these apply, another possibility for the advanced users daring to play in a "what do I get to lose at this point situation" - to try to connect it to PC and run ADB using terminal emulator, to try to bring it back to life or at least restart/reboot it. http://forum.xda-developers.com/showthread.php?t=1229804
Good luck & I will check back soon ...
Unfortunately, mine will respond to none of these. nothing shows up on the computer when i plug it in.. not a sound, nothing. i may try booting up my old linux partition and see what /var/log/messages has to say when i plug it in..
i have an inkling that the battery has completely died though.. its a smart battery so has a PCB attached to it. if this has gone then i doubt the tab will power up.. unfortunately, replacement batterys arent easy to source..
i will let you know how i get on with it later on tonight when the GF and Kid have gone to sleep so i have some peace to potter around the house..
cheers for all your help my friend!
Today I plugged it in to my computer.
There was a white flash on the screen then same thing happened again.
The red light will blink sometimes or it will stay on as if it is charging but nothing is showing up on the screen.
Does anyone know how to open up the viewpad 7 or a manual on how to change the battery?

removing the back is rather simple.. run a credit card or any thin plastic along the edge starting at any corner.
good luck finding a replacement battery though.. i have searched high and low and cant find then for sale to the public that isn't a bulk order anywhere.
if you do find somewhere, please let me know..
Mine is an olivepad but I think the viewpad 7 and olivepad are the same hardware wise. (I may be wrong).
Maybe we can exchange the battery with another with the same voltage rating. And maybe higher mAh rating for better battery life?
It's already bricked so I don't mind experimenting a bit.
Here are some pictures I snapped.

Open vpad7. Remove the only screw top near sim/micro sd. Remove Batt. connector for 15-30 seconds, put it back turn on and charge fully. (Its bcoz of fully discharged batt.)

Viewpad 7 won't charge battery and power on
Hi
Seems like it might be enough to just parallel connect a phone battery, with 3,7v to the battery PCB for a short period, to be able to charge the battery again.
Mogens
I disconnected the battery for 30s and assembled it back again, but the red flashing continues and it can't be turned on or charged.
Battery is over discharged.
1 - Open it and disconnect battery connector on mother board and reconnect and try to charge. If the battery percentage appears on screen appears and moving means its charging. Charge for few hours then turn on.
2 - Disconnect battery connector and charge it for 5 mins by using any 5V 1A power source for any mobile. Then put back battery connector and charge using original charger. If no other 5v 1 A source available, you have to cut the wire of same original charger and use +ve and -ve.

Hello,
I have an unrooted Z2. With around 30% battery left, I put it in the charging dock on my desktop yesterday evening. After 1 or 2 hours, I noticed that the phone is completely dead - no LEDs are blinking, no vibration, nothing. I tried pressing the power button alone, in combination with VolumeDown, VolumeUp, CameraButton, for more than 30 seconds each. I tried pressing down the tiny red button next to the SIM slot for awhile. Nothing. Phone is dead like a brick.
The only result I'm getting is when I plug it into my computer (ubuntu 14.10) - the LED bar on top is showing a constant red color in this case. Doing the button presses outlined above in this situation is also pointless.
I'm installing flashtool for Linux right now, the connection is pretty slow and it will take awhile. I hope to find out more afterwards. I'm a newbie when it comes to flashing sony phones, only found out now about flashtool. Any advice/tip on how to proceed, or if it even makes sense to dig into this, is highly appreciated.
Thanks in advance!
Hello,
are you perfectly sure your dock was connected properly and it hasn't discharged your phone? Maybe there was something wrong with it.
I had similar situation while I was low on battery and I was creating backup in recovery. Then I fell asleep and I have found my phone completely 'dead'. I connected it to the wall charger and nothing. No led, no nothing. I have even connected it to my pc and also nothing happened. Then I connected my Z2 to the wall charger and I left it like that. And after few hours, out of the blue, just turned itself on, just like my old Nokia n95.
I'm sorry it's not quite solution you looked for, but give it a try. Essential is to charge it via wall charger.
Good luck!
Do what @amon87 says OP. Charge it on a wall charger for a minimum of 3-4 hours; If that doesn't work, can you specify whether you were using a legitimate Sony dock or a third party dock? If it was third party, it could possibly have caused a hardware problem with your device via the magnetic charge pins (not extremely likely but not unheard of). Worst case scenario, send it back to Sony in the next few days. The warranty will cover it if you haven't caused water damage or anything like that.
Thanks for your replies! I also hoped for a sudden discharge, so I removed the device from the dock, plugged the USB in directly, and left it overnight - still nothing. Also, I have the original Sony dock, and have never exposed the device to any water.
Found out the model number in the meantime, it's D5303, if it's of any help. Flashtool does not see the device, unfortunately. I just found out that Sony describes an option to restore your device through the official PC companion app - I'll give that a try when I'm home, and will report back tomorrow.
Otherwise I guess my only option is the warranty.
There's also an option to quickly plug in and out charging wire to kick-start the battery. Unfortunatelly i have no further ideas to help you out.
Don't give your hopes up, try again. There's been a thread of a guy whose Z2 turned itself off and it seemed dead, but after a day or two it just turned on.
So, of course it's also not detected by Sony's "Bridge for Mac" app. Plugging it in and out brought also no results.
As the device is still covered by warranty, and I have yet not tampered with it, I've sent it in for repair! My pocket feels so empty now, i wonder how life is going to be without a phone. Apparently they need 5 - 10 working days.
Thanks for your kind support, guys!
Sorry to hear that. Hope it will get fixed!
Yesterday I picked up my phone in the morning to find that it would not turn on. I tried the usual power button + volume button combinations to get into recovery and download/flashmode but the boot loop seems impossible to break. I left the phone with the rubber band trick all night (around 14 hours) to pick it up this afternoon. No 3 buzzes from either rubber band trick, powerbutton + vol up or red reset/off button.
The only symptoms i have is:
When not connected to charger: screen off, led off, no buttons seems to work.
When connected to charger: Red led on, no buttons work.
When connected to PC: Red led on for about 8 seconds then off, repeat. No buttons seems to work.
The red led behaviour when connected to my PC seems to show that the phone is in some kind of boot loop. Flashtool log seems to back this up:
13/054/2015 15:54:43 - INFO - Device connected with USB debugging off
13/054/2015 15:54:43 - INFO - For 2011 devices line, be sure you are not in MTP mode
13/054/2015 15:54:58 - INFO - Device disconnected
This loops forever
Can anyone help me or do I need to get a new phone? The back of the phone have been smashed but I replaced it myself since im on a tight budget so my warranty is gone :/
Thanks in advance :fingers-crossed:
dont rush to replace ur phone, if its a software damage it means it can be fixed.. since the back was already smashed I would advise u to disassemble the phone and see if maybe some flat cable has gone loose. after that u can start doing software repairs.. the idea is that maybe the motherboard has got disconnected from the battery, or the usb port is not attached properly to the motherboard. Im just guessing. If its any comfort in my experiance almost any software issue can be fixed

I have just removed the back. Nothing is loose, out of place or disconnected. But that would have been weird as f since I changed the back in august thanks anyway
@knightofdenmark, You should check the battery, my guess is that it could be faulty. Take it out and get it tested for efficient functionality. If there's no enough power, establishing effective communication between flashtool and phone won't function properly. Good luck
NB: let us know what happens
New battery worked!
So I took your advise and checked the battery. No voltage what so ever, so I ordered a new one from ebay and just installed it 2 minutes ago, works like a charm
Thank you all guys
Good luck

I'm glad it worked out for you. I had similar experience that's why I said so.
