[Q] wont boot - Galaxy Note 10.1 Q&A, Help & Troubleshooting

Hi. So I plugged my note 10.1 into my USB on my desktop today and waited for it to connect only instead the screen went black and now I can not turn it on with holding power button' taking out spent, can't boot into download mode or recovery. Any ideas guys or just a coincidence in timing? Any thing else that can be done or tryed to get it to respond? Or just a toasted note you think? Thanks for any advice in advance

OK so I took the note 10.1 apart and reset by unplugging the battery. That worked but after trying to charge the tab it wouldn't charge or start up again so I had to take the battery loose again. Now I have had an issue where Google play will not connect, did a factory reset fixed that but 30 minutes later it wouldn't connect again. Another factory reset and now its running smooth but absolutely will not charge at all on 3 different factory OEM chargers. I'm leaving it plugged in overnight. If that doesn't work I Intend to flash a custom ROM and see if that helps. If still a no go I will order a charger ribbon from eBay and try that. Could also be a system board but if its that I'll just buy another tablet. unless someone has some further advice

Try blowing some pressurised air into the usb connector, might be a piece of dust or something shoting it out...
If not that I would still be looking at the connector as the culprit as it happened when you plugged in and doesn't want to charge....

Ok so after having tried everything under the sun including replacing the charging ribbon cable I broke down and waited for a 10.1 with a broken screen to become available on eBay. Let me tell you folks that was a long wait at anywhere near a reasonable price. Traded the system boards out and am back in action. So I haven't come up with any reason why the system board charging went cablooey as all the resistors and diodes I tested were fine but there you have it. If replacing your charger or charging ribbon cable doesn't bring your charging back this is what you have to look forward to. The replacement system board that I used cost me $116.00 USD. I hope this doesn't become a common issue for any other users as their units age.

Triumph won't charge

I got my Triumph and it will not charge no matter where I have plugged it in or fiddled with the charger. It does not matter whether it is on or off. I have been using the wall charger that's included and I have tried USB through my computer. Before I go to the hassle of sending my triumph back I wanted to see if there is a solution. Thanks in advance.
The first one I got did this sometimes as well. I took it back and swapped it.
Jumpstart
My triumph would not even turn on strait out of the box. I had to "Jumpstart" the battery, here is a link on how to do it. thejosea.com/2011/02/jump-start-your-droid-when-no-wall.html (Sorry i cant post links yet, gonna have to copy paste)
You pretty much have to charge the battery by its self outside of the phone. Once you do this let it sit charging for about 20 minutes then try to charge it through the phone.
You should only have to do this once.
It seems like the batteries are not being shipped charged and they run "Dry".
You MIGHT want to try a different USB cable.
I'm using my Nook Color adapter(1A) and a generic USB cord which works fine, however one time I accidentally used my Optimus V cable and it would NOT charge while the MT was up and running, however it WOULD charge IF I powered down the MT...
I haven't even tried the cable that came with MT yet... nor have I tried charging via a USB port on my nb, but I imagine that would be REALLY sssslllloooowwwww....
I exchanged my device for a new one, and with my new phone, when plugged in, the lock screen no longer shows "Chargin" with the %. Any ideas how to bring it back?
It only shows that if you're on an AC charge. If you're on USB it won't.
I've tried on 2 different AC chargers and it still doesn't display
Same cord? The AC pins have to be shorted or it won't go into AC charge mode. I have a couple of USB cords that work fine for connections to the computer but will not go into AC mode (the USB cords that come with the Optimus are known for doing this on other phones, incidentally....)
It'll charge without AC mode being "engaged" but at the 500ma rate instead of the 1A rate, so it will take a lot longer.
the answer is simple.....due to crappy crappy design of micro usb the charge port actually comes un-soldered from the board and obviously it no longer will charge nor will usb work!!! now before you ramble on with how do i know i wondered why mine wouldn't worked i opened the phone and notice the micro usb pins were not attached anymore....i have sent this in to Motorola which gives you a 2 year warranty instead of virgin mobiles crap $5 a month insurence then you still have to pay like $100 to get a new phone!!! so i will post how everything goes so far i know the repair center is in McAllen TX and they give you a free 2day shipping label valued at $100 to send in the phone!
You might want to try plugging it into a wall (not pc) and leave it for 20 minutes. Mine ran completely dry one time and it wouldn't display nothing until it charged for a while. If you've already tried this then definitely take it back.

*update* They are fixing my phone now and i should get it in 5-7 business days no problems they received the phone and started the repair
I had the same problem but different solution.
I too let my phone completely discharge to find that it would not indicate that it was charging or even power on with or without the battery being present, but I "jumped started" my phone. This is a weird technical solution that went as followed in its entirety, meaning, some of these steps might be pointless or useless but I did them and I now have a working resurrected MT in my hands that is charging. This solution is assuming that there is no problem with the micro USB soldering on the main board.
"Jump Starting"
1) Remove the back casing and your MT battery and place both to the side, but keep the battery close by for polarity reference.
2) Have another battery of the same 3.7v that is charged (disregarding mAh).
3) Now here is the fun part and pay CLOSE ATTENTION to POLARITY!!!
-Get two spare wires, preferably of different colors so you can tell the [+] from the [-].
-With the spare 3.7v battery you have, in what ever way you can, connect your spare wires to it, paying close attention to polarity.
-Now that you have your spare battery wired, CORRECTLY connect the wires to the inside connectors of your MT what ever way you can, paying close attention to polarity.
Being [+] connected to [+] and [-] connected to[-]
4) Boot your phone until you know you are at the home/lock screen. Then remove the wires from the MT battery connectors.
5) Use this same battery and connect it to your battery for about 30-60 seconds, paying close attention to polarity. This will give the battery some juice for the system to recognize.
6) Place the battery back in the phone without attempting to turn it on and return the back case to the closed position.
7) Now connect your MT to a powered micro USB cable and see if the red indicator charging light turns on.
-If so then great!
-If not then you may have some other problems
-If yes and no, as in the cable has to set a certain way for it to charge then just keep on reading for that fix as well.
"Loose Connection Fix"
This is how I fixed my loose micro USB cable and it worked for me, but I do not have soldering problems on my main board of my MT so proceed if you think this will help.
1) Your micro USB male side of the cable that plugs into your MT should look something like this (excuse the crude drawing of letters)
{the dots are empty space}
____________
\................... /
\UUUUUU/
2) Get a pair of needle nose pliers and SLIGHTLY pinch/squeeze the center of the male port closed so it looks like this
____...... ____
\.... \...... /.... /
\UUUUUU/
Except not that extremely bent inward, but you get the idea.
This will force the male tongue in the MT charging port to be forced onto the pins inside the micro USB cable for a better connection and thus fixing the loose connection problem
I hope this helps someone, it helped me save my $300 paper weight from actually being a paper weight.

I let my battery die down and also did a battery memory reset, then the phone acted bricked.
Then I tried this to revive and it worked!
Thanks for the help here I did this but when I connected the batter to the phone nothing happened. I connected battery to battery let sit for about 90 sec put it in phone and plugged in and the red light is now on!
Thanks!
Well,
add my phone to the list. It started about 2 weeks ago when after completing charge, instead of maintaining trickle charge it just let battery drain. I woke up couple of times in the morning finding the phone's battery on it's last legs. Now it simply refuses to charge by anything but my car charger. Lucky for me (and I thought I would never say it in my life) I have a long commute to work and it allows me to recharge the phone while I enjoy typical traffic delights.
I am going to call Motorola and discuss my options with them. I hate doing this as my phone is long since rooted and running CM7, so I will probably have to revert to factory settings before sending it off and if they decide to exchange I would be running a chance of receiving one with bad GPS.
yes i've had this problem to i have to charge my phone on a Samsung charger no motorola charger will work on my phone.
Sorry, I'm somewhat new here.
I have a Motorola Triumph and it just stopped working. The general idea is that the Micro-USB port was shoved up into the device?
How do you go about contacting Motorola about sending it back to be repaired?
I have delt with this problem SO MUCH, have you tried my battery charging fix yet ? I have the link posted in this section called battery charging fix, Hope this helps you it sucks when your phone won't charge.
Well the problem is that it won't even turn on. I think the battery has some kind of charge but when I hit the power button, it vibrates like it's booting up then stays off.
I don't know that much about phones, but from what I can gather off Google and the various threads on XDA (Great site, by the way!) the general consensus is that it's the micro-usb port.
Granted, I may be wrong, which is a very real possibility. Heh.
Well 2 things, have you replaced your recovery with the clockwork recovery image ? If so try any means nessary to get into recovery, My old Triumph would NOT charge with any motorola charger, I belive this is a defect with the triumph. You might try a powermat of some kind to get enough power to get to recovery & do what my guide says to fix this most pain in the ass problem, Or get another battery & follow the guide. It's worth a shot anyway. otherwise you've got two options replace it or open it up, if you're gonna open it up then get a super fine sautering tip or file one down to needle size, this is how I do precision sautering on circut boards.
No, I had downloaded Clockwork with the intention of installing a 2.3 rom on it, but never got around to it. As for the charger, my Triumph charges with any micro-USB, from my old LG and Samsung chargers to the Motorola charger that came with it. It acts weird though when I plug it into a computer, saying it is connected to a computer, then that it's not, then that it is, then that it's not, repeatedly. I usually just end up turning it off so it won't do that.
I find it weird, though, that now when I try to charge it, the charging light up where the speaker is will not come on, as if it isn't charging. (And I don't think it is charging.)
I've also tried putting it into the "recovery mode". (Like I say, not too knowledgeable about phones yet. Learning experience. ) When I boot it up (into "recovery mode" or "regular" (?) mode) it just vibrates like it should then does nothing.
Edit: It finally did boot into the "recovery mode", but the touch button things at the bottom (menu, home, back, and search) don't do anything, and I cannot get into the menu to do a factory reset.
I don't think it's the battery now? I am more confused then I was when I started, and appreciate any and all help!

[Q] Battery not charging

I touched on this in the EOS thread, but I've discovered it's probably not the ROM's fault and some other problem. I was staying in a very old hotel, which I assume had very poor electricity (not sure if relevant, but wife's iphone was charging slowly too, so maybe it could be part of the problem - way too low voltage or something). Plugged the (TF101) in and it charged barely, if at all. If I recall, the wall adapter got hot on the first try (didn't really take much notice as this has happened semi-frequently since I got it - might describe it more as "warm" in the past, where in this case I'd call it "hot") and from then on probably charged to about a max of 25% in 24 hours. So assuming the problem was the hotel, I tried it again at home, where I knew it always worked, and it still doesn't charge. so...
TL : DR - charger isn't charging - thought it was the electrical supply but it's not (though it could have started the downward spiral of breakage)
I tried freezing the adapter, bending pins, hard reset/cold boot, etc as per different threads on the subject. Didn't help.
Tried plugging the USB cord into a PC and it shows up as a connected device - doesn't show charging on the Transformer, but I don't think it's supposed to - so I think that means the cord is okay.
I plugged a Blackberry with its USB cord into the wall charger and it shows "charging" so it would seem that part is okay - but not necessarily definitive proof as it's a completely different device, just my only other USB device I could test.
This all happened right after flashing the newest EOS Jellybean ROM (from #70 to #72 - no full wipe - cache & dalvik wipe only), but I've switched back to Megatron, which worked perfectly in the past, and nothing changed with the charging. So unless it's possible for parts of the EOS ROM to remain (after a full wipe this time), it would seem the problem is with the charging circuit or the battery itself, right? Not sure what steps to take to test that.
I think I will probably try a new charger anyway, as that seems the cheapest of the $$$ options to try first, but are there any tests I can do in the meantime without spending money on replacement parts? At the moment I have it plugged in with the power off to see if that does anything - will update with any positive results
(Sorry for long-winded question, I wanted to get as much relevant info in there as possible. Hopefully I got it all)
Start by buying a new usb cable, that fixed my issue. Wall socket and usb port only trickle charged my tf101 (about 48 hours for full charge) tried all the freezing, bending pins but nothing worked. I then brought a new usb cable as a last resort (Wall warts are quite expensive so i was apprehensive of buying a new one) and it started charging straight away. seemed strange because the charging issue was just out of the blue (No damaged to the cable)
doubt this needs an update, but my new charger and (longer!) cord came today and it's charging my tablet perfectly. thanks for the info
now to catch up on 2 weeks worth of ROM updates
Dunno if its the right thread but I was also wondering:
My TF101 charges perfektly with the Wallcharger (TF to USB Cable + Adapter). But as soon, as I put
an USB-to-USB-Cable between Adapter and TF-USB-Cable to enlarge the range ... it wont charge anymore.
But: if I connect the same config it to my PC... I'm fully able to Up/Download/ ADB etc... so it can't be the connection
at all.
What's the trick? What am I missing?

[Q] Need Replacement Charging Port

The tablet needs a new charging/interface port and was wondering if anyone knows where I can get one?
I have searched Ebay and the net for a used/new one. The port looks fine but when plugging the cable in it won't charge. Sometimes I can get it to if I push and hold it just right however this is tricky to do and does not work often. So right now it is a dead brick. The pins must not be making full contact for some reason.
Ive bought parts from these guys before, I don't see a charging port but might be worth giving them an email and asking

Thanks but I would rather not have to order parts from Sweden. If I have to I'll just keep watching Ebay. Every so often one pops up but doesn't last very long.
Good luck
The parts I ordered took about 4-6 weeks to arrive iirc
Just installed a new (used off Ebay) charging port with fingers crossed that it will allow the tablet to charge. I also have a new high quality charging cord (PWR+) and two ASUS wall chargers that I know work. Plugged the tablet in and was relieved to see the tablet come right on and show it charging. Let it charge to about 20% and then decided to unplug it so I could put the ring back on the tablet so it is all back together. Get the ring on and plug the tablet back in and nothing. I'm about to throw this thing in the trash right now. So fed up with these charging issues. What changed? All I did was unplug it, put the ring on, and plug back in.
So for kicks I decide to try the other wall charger and what do you know....it came on immediately and started charging and is still charging. I'm afraid to touch the thing now. Seems once it is charging and undisturbed it will charge to 100% no problem. However, when going to recharge it won't charge. Could there be something in the charging mechanism causing the thermal to trip in the wall chargers? Is there possibly a small short somewhere in the charging mechanism? Anyone have an opinion on why this is happening? Only other thing I can think of is doing a full wipe/reset and maybe flashing another rom (is currently on newest Android Revolution HD) once it is charged up.
Could the ring (I assume you mean Bezel ? ) or the screws near the port be shorting the charging port to earth/ground/chassis ?

Yep.. Sry.. The bezel. Not sure how but anything is possible. Would indicate to me a faulty charging port or charger cord and is happening on multiple. Tablet is still allowing me to charge it at this time after switching chargers and with the bezel on so will have to see how it goes.
Sent from my tricked out S4.
Fingers crossed it was a coincidence with the first charger, if not, I'd try taking the bezel off again and see if you can spot the short / see if it works again with the bezel off, or even just with the screws out

Note Pro 12.2 wont turn on not rooted (Solved)

Hello guys, i am hoping that you can help me because i don't know where else to turn. I purchased a Verizon note pro 12.2. I was using it and on for about two weeks until i got my surface 3. Two days ago i went to use it and it wouldnt turn on. I assumed it was the battery so i put it on the original charger for about an hour and attempted to turn it on. It booted to the Verizon logo then flickered off. I put it back on the charger overnight thinking that would fix the problem. When i attempted to turn it back on it loaded to the Samsung splash screen and then turned off again. When i plugged in the charger once again the grey battery icon came up saying the battery was 100%. Even with the battery saying it was 100% it still wont turn past the splash screen. This only happens when it connect to the charger. it doesn't do anything at all if it is not plugged in. I have taken the battery out and reconnected it... still nothing. Looking at other post i assumed it was a software issue so i tried to sideload a stock version (Cant use odin because the tablet cant even boot into odin mode) of P905VVRUANK1 which is what the tablet was running. I got the error footer is wrong security authentication failure. I dont know what to do. Please help!!
correction i did not sideload (wrong terminology) i tried to flash through recovery mode.

Probably you have a loose or cracked battery connector. Try this, power on while pressing hard on the back near the center ( location of battery connector ). If it can boot this way, you need to re solder the battery connector.

I have tried this but still nothing. I also switched out the battery with another note pro and that tablet powered on with no power. when i tried to use that battery in mine i still got the same result.

I have seen this problem in many Tab Pro or Note Pro: it cannot turn on even with full battery. When battery connector's pins are open or cracked, your tablet won't be able to turn on. There are too many unknowns such as USB charging port, battery connector, or battery. You need this tool to find out where is the problem:
http://www.ebay.com/sch/i.html?_fro....TRS1&_nkw=usb+voltage+current+meter&_sacat=0
When charging, current should be 1.7 Amps.
It sounds silly but I see many users cannot figure out the problem which simply comes from bad USB cable or charger or USB charging port. This tool will eliminate guessing.
Since checking battery connector requires experiences to know the solder joints are good or bad. My recommendation for your problem: Re solder the battery connector if everything else: USB cable, charger, USB port, battery are in good working condition.
Use another battery you won't see the difference if battery connector on main board is cracked or loose.
Cracked battery connector is very common in this tablet but most average users won't see it or don't understand why it's the source of problem.

I do not believe that is the issue. the charger i used after the fact was a samsungng 5.3v charger thats belongs to the other note pro. im assuming if it was a issue with the amp that the other note pro would have the same issue... could it have something to do with the bootloader maybe.... or maybe theres a file i could flash that im just not aware of...

Slowest Battery Charging

Alright, so here is a fun issue to deal with. My notepro has always been a little slow to charge, but most of them are. However, its gotten very bad.
I have had issues with screen flicker and a little heat issues and some other small things off an on. So, fed up with it, a few days ago I rooted the tablet. It worked fine. Then I tried to install a new kernel and rom that was getting good reviews. However, when i did this, I couldnt get past the boot screen. Several reinstalls of stock and customer kernels later, my tablet started flashing and eventually died. When it was plugged in, it would show the battery icon with a circle in the middle but then die. Several tries to fix only seemed to solidify the tablet's fate.
However, yesterday I gave it another shot. I assumes the tablet had heated up and made the solder loose, so after a while it was solid again. It started charging, and after reinstalling stock rooted rom and stock kernel repeatedly, it was working again. I then installed the rom and kernel I was trying to before (I had to have a custome kernel to be able to control voltage for the screen flickering issue).
Now it is actually working. All functions are working, and oddly enough I am not seeing any screen flickering.
Only one real problem remains. Battery charging. The battery is charging so slowly that when the tablet is turned on, it doesnt charge at all, it creates a stalemate between charging and draining. It also drains pretty quick. The power drops about 5% in about 5-10 minutes of full screen brightness use (I was testing it this way to try and see if it would flicker again.
Its been charging for about an hour now, and only gone up 5%.
I have tried a couple cords and different bricks, but to no avail.
There are some thoughts, I am wondering if the tablet is only drawing power as if charging from usb, so only around 0.5a instead of 2.4a or so . I am also wondering if there is still a hardware issue.
I do not think it is the rom or the kernel, as this issue was happening as well after I got the tablet working again on stock but before I tried isntalling the rom/kernel again.
Any suggestions? I would be very appreciative.
I had simular problem with very slow charging, reboots and bluescreen. I opend my note to check battery plugg for broken soldering, but I found no problem with it. But to check turely i unplugged battery from main bord and replugged it again. After that I had no problem at all, now its charging normal, no reboots.. stil working perfect after averyday use for about 8 mounts......
If you are using usb cord not usb3 cord it will charge very little when using tablet . Mine will charge when off and below 25% to full in 7 or 8 hrs overnight.

Could be a bad charging port dock/flex cable. These are actually pretty easy to replace and can be found on Amazon. I had to replace one on mine. Try searching for a usb charging port dock flex cable for samsung galaxy note pro. That will cause the issues you are seeing. However the screen flickering sounds like a voltage issue caused by a cracked solder pin from the battery connection to the board. Which is very common on these and hard to see without an electronics magnafication glass. You could try taking the back off and pressing the battery connection firmly while plugging in your tablet and powering it one to see what happens. Either way sounds like a hardware issue.

Ok Guys, had the same problem with my 12.2 samsung tab pro, changed usb chargers, cables etc.
Found that the connector on the tablet itself (female) did not made good contack with the male usb.
So i simply , very careful, with a pair o pliers closed both tips on the usb conector, so the cable enters more tight. And voila, the usb amp meter i had showed a rate of charge from .33 amp , jumped to 1.73 witch is more than enough to charge and use tablet at the same time.
You need to do this at the end of the cable that plugs on the tablet, that is kind of double, maybe a e.0 usb or something like that. Make sure to close both tips. You want a tight connection
