plzzz dont let it be a brick!!! - Nexus 9 Q&A, Help & Troubleshooting

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.

[Q] How to unroot without charge

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.

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.

Galaxy S4 won't charge.

Help! My Samsung Galaxy S4 won't charge or connect to a computer. I've tried different chargers, cables, plug in locations, car, 110, computer. There is no dirt. Connection is clean. I have a spare battery and both of them will charge on the battery charger. I have tried backed up roms. I have done a factory reset.
All of this and nothing helped. Am willing to try anything. Verizon is going to send me a refurb.
Help please.

Is there any indication of a connection being made? If not, you should just wait for the refurb. If you have rooted, I really doubt Verizon will honor the warranty on the broken phone. I wish you the best.

sounds like contacts are on the phone side are damaged or the micro usb port is damaged.
Have you plugged into to a pc just to see if it can "see" the device and connect?
You stated it cannot connect to a pc, so i would suspect you have a bad micro usb port.
if you can connect, its not the port, and try taking an eraser and gently swabbing the contacts on the phone side.
also, make sure when you insert the battery there is an actual contact established. sometimes when pulling/pushing the battery in and out, those contacts sink further into the device and finally when you insert a batter the contact is very poor. you may need a tool or tweezer to just VERY, VERY GENTLY raise the contacts if they sunk in to far......but be careful not to pull too hard/much they can snap and you will probably void any warranty......

I am having the exact same problem. I have replaced the microUSB charging port on the phone and it still doesnt charge with the new port. I'm not sure what is going on. NEED HELP BIG TIME!!!
I'm having the same problem as well. It has been like that for bout a month or so now. I googled it and it seems to be a problem with the s3's and s4's. I'm not so worried about it as I have a spare battery charger and I have the wireless charging receiver on my s4 and it charges my phone just fine.
I had this exact problem I believe...tried several different chargers...everthing. Try turning the phone off and see if it takes a charge. When mine was off it would show a gray battery and vibrate every 5-10 seconds. I figured it was an issue with the charging/usb port but all of the sudden my phone started charging normally and is visible by a computer. Lasted for about 4 days and have been in the clear for about 3 days now. No clue what went wrong or why, but try what I mentioned above by charging with phone off for a half hour or so and see if it has charged at all. If you need a new USB port, not all GS4's have the same port, so you must get a verizon specific one (ebay). usually run about $20..or $65 installed at a phone fixing center. I didnt want to lose MDK, so I was prepared to just charge externally, but ended up not having to...yet
It happened to me also. I had some intermittent luck with blowing out the port with air from my air compressor. But in the end it just stopped working and Verizon sent me a refurbished one.
I Also have this problem!

Have you tried powering down your phone and seeing if that gray battery comes up and you get the vibrations (while plugged into charger)? You may need a new port, but since your under warranty, you could get a replacement unless you want to charge externally
S4 problem after update to 4.3
Hy,
I have a similar problem with my S4 (i9505), won't indicate if it is charging or connect to a computer, but while the charger is conected to S4, the battery level is increasing. When the battery is fully charged S4 is SHUTING DOWN!!!! And it wont start by pressing ON/OFF button, it will only start after I press Vol Down+Power, after goes to Download Mode and press Vol Down .
Tryed in many ways to fix:
- restore-
- hard reset
- changed te battery and charger
-i\ve changed even the usb port (flex cable) and =no results...
All problem started after update to 4.3.... and it is not an isolated case too many people complains about this 'awesome smartphone' with 'awesome issues' .
So, if anyone have any ideea how to solve this issues....
{Sorry for my bad english}
Had the same problem...lasted for about a day, I had to take a dry q-tip and clean the charger and the port where the phone charges and was able to get it working again. If you are rooted and are having issues go to amazon or ebay and get a wireless charger and it should take care of your problems as well

Ok....wireless charger...but what about syncing with the PC?
Now I have JB 4.3 , for a custom ROM I need to use usb cable to connect to PC, rigth?.
For me it is annoying, because I do not know for sure if this is caused by updatind to 4.3 or is a harware problem.
My wife's phone had this issue last night and this morning; charger or computer, it wouldn't charge. I turned it off, took out the battery, SIM and uSD card and put them all back in. After that it started charging again. I don't know if this will solve the problem long term, but so far it seems to have done the trick...

Lucky you...I did more than that, but no result in my case. I found on ''community.verizonwireless'' many more similar cases where ''customers support'' tried to avoid giving the answers for a real solution.
Well, our luck didn't hold. My wife's S4 wouldn't charge again last night. I tried another Samsung charger and a different cable but it wouldn't work either. When we left the house she tried it on the car charger and it worked great. Trying various other chargers we found that a kindle charger wouldn't work, but other third party chargers would. Even her PC USB port seems to work and she doesn't have the drivers loaded. For now she replaced the Samsung charger and cable that came with her phone for one that came as part of an accessory pack and it's happy again.
I have no idea what's going on with the thing. I asked one of the guys at the Samsung booth in Bestbuy and all he had to offer was reflashing the ROM or un-rooting it and doing a warranty exchange...

Can you check, please, if your new data cable has 4 or 5 pins(look to the side that connects to your phone )?
My first s4 done this. So I ended up with a replacement mdk phone after I figured out if you bend the lil piece in the charging port of your phone (not too much BTW) the charger will slide into the port as it's meant to.
Sorry I can't remember the tech term for that lil pin inside the charging port.

I think the S4 is compatible with QI compliant wireless chargers. Amazon has some that are only $20... might be worth the purchase.... hell if I didn't have this tank of a case on I would buy it.

Thanks for your answer, but I already did that....I even changed the flex cable with charging port, no luck for me.....
I think this issue it is not hw problem because, look what I did today:
-I put a new Rom , so I used MIUI FOR I9505 from http://forum.xda-developers.com/showthread.php?t=2306650
And now it behaves even stranger:
S4 is ON and wall charger is conected, (LED IT IS OFF but BATTERY IS BLINKING and is charging ) after battery level go up to 100% and disconect the charger, the LED STARTS TO LIGHT GREEN!!!!
So, now shows that is charging when charger is NOT connected?

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?

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?

[Q] USB charging not working, data connection working

I have found the Xperia Z2 to be an extremely slippery phone and it dropped to the floor quite a few times already, but the last fall seems to have finally damaged it. Now, when I connect it through USB to either a PC or power outlet, it will no longer charge. I can exchange data with my PC, view the external storage etc. just fine, but the charging icon will keep appearing and disappearing irregularly, about once per second. Meanwhile the battery gets drained instead of charged.
I now charge my phone through the magnetic port one the side of the phone, which is working fine. I would like, however, to know if there is a way to repair the USB port of my phone.
Many thanks

Seems like hard to repair. You would need to disassemble the whole device. I'd suggest you send the phone for warranty repair. Just do not mention you let it fall

Look into the Z2 disassembling videos, but I guess you should bring the device into a professional phones repair service.
@MrTheMan I think I know what bricked your USB port. The damage wasn't from the fall, you just connected the Magnetic charging cable upside down... Didn't you?
If you keep tightly in some points, dies it charge then? If not and still charges intermediate then there are two things. Either one of the lines if the port is damaged or the battery is of center. Remove and reconnect. First clean it's contacts with.a brush and pure alcohol. Do the same on the port.
Mine does the opposite, USB is fine(as long as I disconnect at 100% and don't charge with MHL adapter) but magnetic has the issue.

If I remember correctly there is one diode on the PCB that get's damaged :/
I have the same problem, due to magnetic charger..
Surely this is covered by warranty? I'm still under warranty so I will try to get a replacement.
How could they design it so poorly that it can be damaged like this....

Oh, I search some info. The diode just allow electric current pass one direction only. No wonder my XZ2 keep restart after I pressed shutdown because the diode allow the electric current from battery can pass through in opppsite way.
I don't believe it is a hardware problem. You dropped the phone but the USB port is not likely to be physically damaged by a knock. I had the same problem, on a Z2 provided by my company. I have requested a change, got a new one and in a few days the second handset had the same issue too. Two phones, both new, both never dropped, used with maximum care, both with the same problem. The second one wasn't even charged more than a couple of times before failure. And I had tried it as soon as I had it in my hands, just to be sure it worked, and it did, at first. I connected it to a laptop thru USB port (3.0) and it charged. Then updated apps and system to Lollipop, connected it again and it failed. In a couple of days. I'm sure nothing physical happened, unless my USB port fried it. Notice however, that data connection is working perfectly and everything else I connecrt to that port works as well.
I have some mag chargers too, and I don't believe I've ever connected them upside down. The plug is made in such a way the it does not connect if reversed, having one contact circular shape and the other elliptical.
I checked on the Web and there is a number of Z2 owners complaining for the same issue: there's even a video on Youtube showing this exact behavior. Sony seems to ignore it.
I must admit, however, that I'm unable to explain why a factory reset does not solve the problem. Now I'm trying to flash a stock ROM (mine is branded Telecom Italia) and see what happens.

Did you repaired your device. Please relpy this
Phone 2 years.
1. Charged through the USB port on the network 220 (native charger):
It reaches 81-83% of charge and starts to go crazy: flashing red LED charging and says that is / is not going to charge.
In fact, no charges.
I tried different cords and chargers - so everywhere is going crazy with a 80% interest
2. Charged via USB from the cigarette lighter in your car or the external battery:
It's okay - safely charged up to 100%
3. Charged through the magnetic cable:
It's okay - safely charged up to 100%
These are symptoms of what is dying?
Thank you!

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 ?

let it charge for a night period. Then try to flash again.

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 ?
Hello, Did you find a solution to this issue ?

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
