I've just received a cracked s2 gt-i9100 the screen was cracked and didn't show an image but still the buttons lit up and the phone vibrated on touch i ordered a new screen and set about replacing it unfortunately upon doing so I snapped the power button ribbon cable so i'm unable to power up the g2 till the new one arrives, when i plug my phone into my laptop the screen turns on and shows a battery charging however the laptop keeps saying unknown device... I've tried different cables and a different laptop not sure if i could of damaged the usb or if it might be that there is no power button ribbon connected?!
Would really love any help? like maybe there is a way to turn the phone on without the power button for the moment?
Have you installed all the necessary drivers for the phone?

Yeah as far as i'm aware.... + the phone was working in USB mode before I replaced the screen and snapped the power ribbon :/

I don't think the power ribbon cable have anything to do with the phone not being recognized by the computer, but everything is possible. Are you sure you didn't mess up anything inside the phone, when replacing the screen?

So I have been trying to root my phone and have been following the directions posted on the forums here, the problem is, no matter what I try I can't get it to download mode. I've tried volume up + volume down while plugging in USB, tried volume down + power button while plugging in usb, and while not plugging in usb. Nothing gets it into download mode. All the buttons and the phone works completely normally outside of this, and I can get it into 3e recovery mode easily enough. Any help?
Take out the battery from the back to ensure your phone is completely off, then put the battery back in. Now hold down on both the Up and Down Volume buttons and plug the USB coming from your PC into your SGS2. Once you see a warning screen let go of the volume buttons. Hit the Up Volume button to continue into download mode.

I tried that, and did it again just now with taking the battery out. It doesn't work, after like 5 seconds of having the usb plugged in it just starts charging the phone and brings up the battery filling up graphic...
Never mind, maybe this should have been obvious, but I was trying to do this with a generic microusb cord made by At&t (it was what i had closest at hand) and it wasn't working. I just tried it with the microusb cord that came with my phone (samsung made) and I got into download mode right away...go figure.
Interesting...I wouldn't have thought it mattered. Glad you figured it out.

I think some of the microusb cords AT&T sells are specifically designed for charging-only - they short D+ and D- together to force the phone into AC Charger mode.
Which of course makes them useless for data...
(The stock MicroUSB cord is OK - but additional cords can be charger-only.)
Hi,
i have a NT , when i plug in the cable to my pc it shows he usual USB mode.
is there anyway to have it in usb mode but be able to use the tablet at the same time ? in other words get rid of the damn pop up and let me use it while its in usb and charging mode ?
thanks
you could try disabling automount... maybe the USB window is triggered when the SD is mounted for computer use.
That is absolutely correct. If you don't know where to find automount, it is accessible through the nt hidden settings app.
ive also been seeing a weird issue , ive done that in the past , but when my tablet is connected to power / computer usb cable to any power source my touch screen is funky , when im on the lock screen i can do stuff , i can pull the bar over to almost get it to unlock but when and if it does its funky , i just kicked it out off of auto mount and i have what i want except touch screen is not actually working , if i unplug it from the cable the screen works ,
any ideas ?
You could also try "ejecting" the device. That might put it in charge state and allow you to continue using the device.

I haven't noticed the "funky" screen on my NT, but have experienced it on smartphones in the past and it was associated with a noisy charger. Try using different chargers and see if the problem gets better or worse.
ah yes you have a valid point i have two NT's one for me and one for my gf hers blew a charger and we had to have B&N replace the usb port receptacle already , had it less than three weeks. I will try it with her usb cable and see what i get as they changed the whole assembly and if it does not occur with her new cable i will get them to exchange it before the 1st ..
Hello. I read your posts about xperia z2. Unfortunately nothing is working. I don't know too much about the phone because is not mine. It's possible to have taken some water inside. At the moment no matter what I do, only the red led turn on when I plug it to wall charger or usb pc. It is not responding to any buttons or hard reset button under the sim slot. Most of the post are about flashing. But how can I flash if the button are not working? When I open it the battery had 3v. I charged it to 4,2 v but still not working. I also tried with the battery cable unplugged. Do you think there is still something I can try at this moment or it's batter to buy a new motherboard? Thank you in advance.
Have you tried to hard reset using power and volume up? Have you tried to flash via flash tool? If that doesn't work I'm afraid you have to buy a new motherboard.

Hold volume down while pluggin in the usb cable (connected to pc).
LED should turn Green, then you are in flashmode. If pc recognizes phone, try to flash a stock tft firmware.
Thank you for your answer. As I said, the phone is not responding to any button inputs. I tried power,volume -,+,red button under sim tray nothing is working. The only thing it does is the red led turning on when I plug it to usb. I read that a new battery could turn it on. I think the battery is good as long as it holds voltage.
At this moment I am trying the rubber band trick. If this doesn't work probably I need to change the mother board. I looked at the mother board and I can't see any damage (broken connectors, traces of fire...)

I have same problem. Maybe do you know solution? I think this is mb problem, but maybe know how to fix it?

looks like just flash red led, no charging. When trying to turn on I can hear some clicking sound from motherboard, like small relay or something.
Hi,
Please, be patient while reading this post, this is a looong explanation of the brick I am facing...
I recently was given a non working XTZ SGP311 and tried to get it back to life. As I have another one SGP311 (this one is perfectly working), I am able to check many things.
I read most of topics about XTZ unbrick but can't find any way to get it back working.
The problem is that I can't have any signal from usb (data or power). I use a genuine Sony USB cable and genuine Sony charging adapter (coming from the working SGP311). The led always stays off.
I tried the different combos as described (vol- and power ; vol+ and power ; vol+ and vol- and power) during 5, 10, 20, 30 seconds (yes, quite complete tests).
I did a cross check of batteries and inside usb connector ribbon (yes, had to open both tablets for that), the working tablet continues to work with the 2 parts coming from the faulty one (battery coming from dead tablet was 0% charged), so the problem is not on the side of the inside usb connector neither on the side of a supposed dead battery. The faulty tablet doesn't boot, even with a fully charged battery inside.
I luckily own a XTZ dock (SGPDS5) that allows to charge without using usb connector (it uses the 2 contacts located on the left side of the tablet). That's the only way to get something...
Soooo, when I put the bricked tablet on its dock, the red led flashes very slowy (say, 1 second off, 1 second on red, and so on).
When I press vol- and power, nothing happens (no matter 5/10/15/20/25 seconds).
When I press vol- and vol+ and power, idem.
When I press vol+ and power : I got the sequence blinks once white led / blinks 3 times white led (after that goes to slow red blinking about if I keep the keys pressed). So not completely dead.
If I unplug it from the dock right after the third white blink, plug the usb cable to the tablet, plug it to my laptop (with emma running, tried with pc companion too), and press vol-, then....nothing happens. Really nothing. No led lit. No detection of anything from the laptop (or device manager as well). It would have been the same if I would have kept it unplugged.
To sum it up, the only thing I can have is 1 or 3 white blinks after having plugged the SGP311 on its docks.
IMO, the trouble comes from a faulty component inside the tablet. Maybe the one that manages the connection from the usb ribbon plug. I checked the tiny plugs inside the tablet (once dismantled and back repacked too), all seems in order.
Your help is welcome !
This is similar to an issue I have it sounds like, you can still flash stock rom by holding power + volume till it blinks 3x then plug USB in and hold volume down immediately.
This gives flash mode, you can use flash tool to put stock rom on with this. The issue happens when it's acting like there's no OS it seems. Problem is mines doing this everytime I flash a custom rom, it's fine with stock aside from **** wifi
Thanks for your help. I tried that yesterday and it did not work.
This may be related to the way of reset I use (but I can't have any other).
As I can't get any white blinking led when connected by the tablet micro-usb port, the one and only way to get the 3 times white blinking led is when the XTZ is on its dock (SGP DS5, power connection only by lateral contacts).
What I tried yesterday was to get the 3 time white blinking led (vol+ and Power), then output the tablet off the dock and connect a usb cable to a laptop running Sony Emma (from micro usb tablet port to usb laptop).
Precision : I kept VOL- pressed when pluging usb cable to laptop.
No result at all. No detection (either Emma nor windows).
Any idea ?

Thanks for your advice, I appreciate.
But I swapped batteries from the working XTZ to the non-working one and put a (about) 60% charged battery into the bricked XTZ (both batteries are charging when set into the working XTZ). I will try anyway.
The problem is that the non working XTZ does not charge either through usb or through the dock. The only interest of the dock is that this is only situation where I can have the "triple white led blink" (but nothing more).
That's why I need the working XTZ for charging before doing anything with the non working one.
What I could try would be to connect the lateral contacts with wires to the dock in order to keep an access to the usb tablet micro port and connect it to a laptop.
But this may be hairy as this would give 2 ways for power (one by the dock and the other by the USB port), and may produce a short circuit...
Any XTZ power experts around ?

Well, not a real solution...
I bought a cheap xtz with broken screen and got its working motherboard and put it instead of the other one.I got the lte component too with its antenna and put it into the 1st xtz that was not supposed to have lte.
So now, on one side I have a xtz with faulty motherboard and broken screen, and on the other side a refurbished xtz with LTE !
I like very much this tablet. Very handy, easy to dismantle and easy to swap its components.
The only drawback is no more support for Sony.
Thank you for the answer
So, you are saying that if I replace the motherboard I can fix that ? I'm looking for motherboard on ebay and I found one for $28 usd + shihpping.
Thank you for answering and take care.

Yes. I think this should be good.
Don't care about the exact matching of the product code: as long as it'll be xtz, it'll be good (16 or 32 gb, with or without lte, and any region should match).
Did you opened it already ?
Yes, I opened 2 years ago cuz my son broke the power jack connector then I replaced that twice.
I'm also tech guy, I can replace that, but won't expend more than $50 for a new motherboard. I'm looking on ebay now.
Thank you

So i found a usb cable at work so i decided to take it home and use it. When I plugged my tablet in, it seemed a bit loose so I decided not to use it. But when I plugged my original charger, it wouldnt charge....that was 2 days ago and still no charge.
Im pretty sure its bricked because it doesnt turn on, doesnt show its charging...nothing. I guess i just want someone else to tell me that its done for and time throw it away or maybe have someone more knowledgeable repair it..

So what makes you think it's a brick? Is it just a dead battery? Did it boot before? Have you opened it to check the battery connection?
I replaced the USB daughterboard on mine. Like $10 and 15 minutes. Couple screws and ribbon cables

Does the white light at the bottom flash when you try to power it on while it charges?
try this:
Plug your N9 into a good 2.4amp output USB brick
hold down the power button
If the led doesn't flash 3 times annoyingly then you are out of luck. I don't know how to fix it. I have a broken N9 and a good one and the broken one has a dead mother board and sounds the same, but I DOUBT a loose USB cord destroyed your tab.

Mine died too, but the led does flash 3 times. Is that a good sign? My USB port began failing and it was getting harder to charge. I left it plugged in over the weekend (forgot about it) and on Monday.... Nothing. But it does flash the led 3 times when I plug it in, sometimes. I probably need to replace the USB board again. Leaving a USB otg stick plugged into it for movie viewing in the truck is what keeps damaging my USB ports.
Update: I finally got it to charge and boot. Just had to hold the cord just right, and plug it into an outlet I have converted to USB next to my couch. New USB daughterboard ordered and on the way.
Try putting it in APX mode and charging it. Plug it into a computer and hold power, vol+, and vol- until the tablet is detected. Leave it overnight, then hold the same button combo for 15 seconds.
