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

sorry to hear about your troubles. it is 'rare' to hear about the factory cable & charger going bad. they seem to be 'very good quality' like the NT. . could it be that the tablet is in a 'hung / locked up' condition where its drawing plenty of milli-amperes even when it 'looks' like its off ? ? ? . if you look at the display, at an extreme angle, can you see the back light 'on' ? . did you try holding the "N" button down for twenty seconds ?
ok so a bought a new cable from barns but it doesnt have the charge light on it just has a "n" but without the light. while at barns i had them try to charge it and they had the charger with the light. it would give the message while there that battery is low and needs charged i dont get that with the current cable. the bottem right side of the nook does get hot though after its been on the cable for a bit. ive tried the power button the 'n' button both of them and i dont see a change in the screen. im headed to barns to replace the cord i bought for one with the light. ill update after that.
Power cable bad

I have found that the power adapter is very good quality. However, the Nook cable -- not so much. It is especially vulnerable at the end that plugs into the Nook. It is the same adapter/cable that the Nook Color uses and I have had to replace two of them plus a friend recently had to replace one.
If you call the B&N Tech Support, they will send you a new cable for free. (At least they did for me. They even sent it 2-day.) Even if you buy a new one at B&N, still call and get the broken one replaced and you will have a spare.
Note: You CAN use a standard (non-B&N) Micro-USB cable to charge the Nook but it will not charge as fast as the B&N cable - and it may not even keep the device charged if the screen is lit. They built the B&N cable to add extra connections to carry a heavier load and therefore it charges the Nook much faster. That is why you CANNOT use the B&N cable on a non-Nook device. You CAN use the B&N adapter to power a standard USB cable & attached (NON-B&N device) though.
To answer your original question. There are certainly very technical ways to unroot the device without charging the battery. But for normal users, there is none that I can imagine.
Hi I have a Sony Xperia S SGPT-121US the "multi port" broke and now the tablet will no longer charge. I have stuff from work I really need. Is there any place I can purchase a replacement? (tried ebay,digi key already) Or can I charge thebattery any other way like Wireless or anything?
Thanks in advance for any feedback.:fingers-crossed:

Unfortunately it's the port I just paid $40 for a brand new charger (so mad) I can see a corner of the dock got broke off. I'm bidding on a parts tablet on ebay right now fingers crossed. Otherwise it's for parts on ebay and try to get back some money?
Different problem now
So I decided to open up the tablet and charge the battery by connecting a usb cable with one side stripped and soldered the positive and negative to the proper leads on the battery. So Now I get a red light flashing 10 times on the side where the power button and volume buttons are. Before I had nothing at all. Any Suggestions?

I would suggest you send it to Sony for repair, but I don't want to spoil all the fun you are having.

What voltage is the battery??? I have used a stripped USB cable many times to revive a dead phone battery. 5V => 3.72V is safe enough... I know the battery from the STS is a 9Vish (from memory) prehaps you could wire off the end of your tablet charger for the extra voltage?? SOUNDS LIKE FUN
so what did you end up doing? trash, won your ebay auction? sell yours??? send to sony? i'd like to know since parts for these things are going to be hard to source. also what model do you have?
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?

Maybe you try to repair phone with Compagnion?If phone detect charger maybe will detect that is connect to PC.

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.
Hello and good day.
I wondering if anyone here knows the Xperia Z2 Tablet well enough to help me proceed to the next step in getting my xperia z2 tablet back in working order.
A little history; I used the tablet on/off when I first bought it, then life took over and I had no time or use for the tablet. Now with a new job starting in 2 weeks time, I could very much do with getting the tablet to work.
I thought the tablet was in some sort of Sleep of Death but it appears that was not the case; I originally tried all the different button combinations, letting it discharge and recharge, used PC Companion to repair, Used Flashtools to repair.
Now, the strange bits; the tablet won't respond to button presses UNLESS I have the micro usb cable plugged in either by charging or connected to a PC/Laptop; whilst connected to a charger it will do the 3 vibrations/led routine. when connected to PC/Laptop it will pretty instantly go in to fastboot mode. and this is the strange part, reboot the device in to system (I also have to quickly remove the USB cable) and can hear it boot up.
all that happens with NOTHING on the screen.
So I had an idea; I attached an MHL cable. Lo and behold I have a picture on my TV, but still nothing on the tablet.
So does any one know where to go from here? could it be a lose connection to the screen??
Seems like a faulty logic/mother board
just need to find a source..
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.
