My note 2 just died - Galaxy Note II Q&A, Help & Troubleshooting

Hello, my rooted Note 2 just died. Yes just died.
First of, I'm sure that there's no problem with my firmware and the custom rom that I was using. I can't even open recovery, I tried connecting my phone with PC but this didn't work. I wasn't overclocking my CPU, my batteries are fully charged, even I have checked the voltage and it was 4.2 volts. I think that something killed my eMMC (?) But how can this be possible?
Let me tell you the story: I was playing CS:GO, and we were losing, then I checked the clock (on my phone). I even watched a video on YouTube and everything was working perfectly! After about 30 minutes I tried to unlock the screen but.. WAIT. MY PHONE WAS NOT ABLE TO OPEN. IT WAS GONE. I was really shocked and don't know what to do
SO, WHAT CAN I DO NOW...
Thank you. :fingers-crossed:

oh sorry to hear that have you tried to remove the battery for a while and reinsert it ? when u charge it is the notification led working ?i thought my emmc was dead also but turned out battery was so empty it didn't give any sign until for like 30 mins after charging it (sorry for weak grammar

My Samsung Galaxy Nexus won't turn on

First of all I read all the possible posts here in the XDA forum about this problem but no one was able to help me :s
I was listening music with my cellphone than it crashed and turned of from nohting. My first thought was "Damm, it crashed!" and I removed the battery and after a couple minutes I put it back and than the cellphone never turned on again. No battery status is showing up, no leds, odin and flash mode doens't work either. I don't no what to do :s
I tried this:
◘ Unplug from USB, remove battery 5 min, put it back
◘ Odin and Flash mode
◘ Turn it on without battery on pc
◘ Turn it on while recharging
My GNexus model is a I9250 GSM.
Could you add some more details? How long the phone's been in operation, refurbished?, rooted?, your current ROM, kernel, radios, advanced kernel settings such as voltage changes, any tweaks, battery type, temperature.
This exactly happened to me on my DroidX. I spent 2 weeks trying everything to revive it including taking the phone apart before adding it to the pile and getting my current GNexus Toro.. so I know how much this sucks. I'm not an expert on phones bricking but I know that connections can go bad or come loose, especially if the phone has been dropped or other impact, components start to lose their integrity over time and voltage shorts 'burn out' op-amps. You mentioned listening to music, so I'm wandering about the IVA components burning out, which usually has voltage too high especially on boot... Hope you can get it working.

Well first of all I thank you for your concern and my phone is on again, thanks to my uncle. The phone is '4 months old', I rooted last month, bootloader unlocked and I was using samsung stock rom (4.2.1 JB). Yeah, that really suck monkey b*lls. If you got the same problem as me (I really hope not) that's what you should do: First remove the battery, plug the charger and than put the battery back. In my case, It kind "shorted" the battery and my phone is back on. I was reading posts and posts and discovered that GNexus has this problem and a lot. Dunno when it can happen again but I really don't want a paperweight. Once again, thank you!
Glad you got your Nexus back up and runnning. Thanks for posting back with details after you figured out the problem and got your phone working, +1 right there. There's always a good chance this will help out someone later on. :good:
Confirmation: balums worked for me
balums uncle's solution worked for me: specifically, (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button.
Thanks balums!
Does anybody have technical (design/EE) insight into what would cause this?
This was starting from a device that appeared totally dead.
The battery was *fully charged* (and showed up that way immediately when the device finally booted).
I had done the obvious things of removing/inserting the battery, cleaning contacts, checking the USB power connection.
Was about to pull it apart when I saw balums post, saving me huge time.
Device is about 16 months old. Stock OS and settings. First time this has happened.
Search terms:
CDMA (Verizon) Samsung Galaxy Nexus -- SCH-i515.
Phone won't boot. Device won't turn on. Won't start. Dead. No worky.
Thanks,
Seth
Awesome! You trick worked, balums!
Interestingly I also have the standard stock version of OS and Hardware which I bought 14 Months ago (nearly to the day). I was surfing over WiFi yesterday evening and when I turned the phone off I noticed the screen getting grey for a moment, not black. And this morning the Nexus just didn't turn on.
Anyway, thanks for the solution, have a nice day!
That is very odd because my i515 also did the exact same thing and I have owned it for 15 months. I can't wait to get home and try this trick. More to come.
Drew
Thanks!

Hey Balums,
My GNex didn't turn on this morning and I was really confused as to why it would do such a thing, until I saw your post. Thanks a lot for posting your uncle's remedy!
It fixed mine!

Galaxy nexus wont turn on or charge.
I tried (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button but my galaxy nexus still dont turn on. i have 4.2.2 stock rooted. i was downloading something and my screen become weird in colors and i cent use the phone. i turn it of and now wont turn on again or charge.
after unlocking and rooting i installed this touch recovery from google play. [ROOT]Recovery Tools
Excellent! balums' suggestion helped me. I thought I had tried this before but apparently didn't quite get this in the right sequence.
The only remaining issue I have now is that when it does turn on, I've got the thunderbolt on the battery indicator, the phone says it's charging at the lock screen, but when I go to Battery under Settings it says that the battery is discharging. This effectively has my phone in a state where I can't unplug it (battery is too low but it also doesn't appear to actually "charge"). I tried replacing the Micro USB charge port PCB board and came up with the same results. To me, this seems like a problem and may indicate a motherboard or battery connection issue. I used the "Battery Monitor Widget" and it indicated that it was getting AC power. Any thoughts?
Thanks to XDA and Balum's suggestion! I thought my phone just died! It was on 70somethign % battery last I looked, connected by USB to the PC and I don't know if I turned it off and walked away for a while or if it turned off by itself, but it would not turn on no matter what I did after I got back to my desk. It is on Android 4.3 takju stock not rooted.
Thank you all again for the instructions on how to revive the GNex!
Samsung Galaxy Nexus won't power up
I got a Samsung Galaxy Nexus. I got it from my cousin and therefore don't have any information about the rooting status as well as the ROM but i guess it was running stock. The phone won't turn ON, it is not detected in the computer. No LED or any other indication. I tried the above method which worked for many people but it failed. What is special about the phone is that the upper part of the screen is heating up more as compared to the rest of the phone. Can somebody help me fix this? Is this a hardware issue?
I have the EXACT same problem as you do. I have no idea where to start to try to fix it. I took a picture, then lines went squiggly across the screen, then it flickered, and died. I cannot power it on at all. I tried Uncle's tricks. No luck.
Anyone have some ideas on what to try? Thanks.

Also having the same problem. My Nexus has been rebooting randomly for the past week or so, and finally, this morning, it refuses to turn on at all.
It's a Verizon Galaxy Nexus running stock, but it's been rooted. I'm using the extended battery. The trick that was posted earlier in this thread doesn't seem to work for me. I've tried multiple USB cables and power sources.
I'm going to try the standard battery when I get home, but I'm not expecting positive results.
Work-around
About two months ago whenever I turned my Gnex off, it became totally unresponsive to all attempts to start again. After a lot of trial and error, I discovered that if I pulled the battery for 30-60 minutes and reinstalled, it would power on normally. I have completely wiped and rooted the phone and the problem persisted.
Today I thought about it some and realized there may be some residual charge in the phone, and my waiting period is to allow the charge to drain. To test this theory, I powered the phone down and then tried to restart - nada. Pulled and reset the battery - nada. Pulled the battery, shorted out all four pins that would make contact with the battery, reinstalled battery, and it powered right up. I have not been able to successfully repeat a fast restart when shorting out all four pins. Pulling the battery and waiting 30-60 mins still works.
Incidently about the same time, my screen has stopped auto rotating (and yes it is set to do so).

galaxy nexus reboot
my galaxy nexus is about 1 year old now and this is the first time that i've encountered a problem with it. It suddenly restarted, and will take about 5-7minutes before it opens, it will be open up to the "X" logo and when it reaches the normal screen it will restart again. I don't know whats wrong with it. please help/

You saved my Galaxy Nexus
Similar problem + water
Ok, so I have a similar situation I believe. My phone took a swim. I left it off and riced it. Later on after I believed it to be dry enough, i turned it on. (wow it freaking worked) After a few seconds of using the device checking screen the phone snapped off and went into a reboot. I waited until it came back and i shut it down and thought I'd let it go over night. I plugged it in and let it charge (charge icon was displaying). Everything looked good.
Fast forward. Morning time. I go to turn the phone on. Nothing.
This time the phone won't boot. Instead all i see is the white battery icon show up indicating the battery is 100%. When i plug it in to the charger i get the battery with the charging bolt, then it shows the normal battery indicator light. After that, I get nothing.
I tried the method I saw above. remove power, remove battery, apply usb power, insert battery, press power. Sadly it didn't work.
Anyone have any other ideas as to what might be going on?

Battery Failed

Hi Guys,
Ive had my GPAD for about 2 months now, i came to use it today and the device was dead. Simple enough i thought the battery had just drained, however when i plugged it in to charge it just did a strange bootloop. The LG screen appeared a battery icon with 0% appeared and then instantly rebooted itself doing the same process over and over.
I thought if i left it for a bit it might need a charge before going any further i.e. battery was completely drained. I have left it for over and hour and its still doing the same thing. As soon as you unplug it from the mains it dies and wont turn on.
I'm assuming my battery has completely failed, has anyone else experienced this with this device. I've owned lots of phones and tablets over the years and have never known a battery fail like this before?
Thanks

If it immediately gave a sign of life when you plugged it in, then it was not off. Power it off with the power button, then plug it in to charge. Try this also on your computer if that fails, and finally, treat it as if it were bricked and thus set it to Download mode, and try a recovery.

I just had the exact same problem myself.
I did use CM11. What did you use?
After going back to stock it worked fine. Now, I am just about to try cm11 again.
Sorry for Kate reply, didn't really Jeep an eye on the thread as I thought it was just dead lol. I used madhi ROM which I think is cm11 based. I'll try and put it back to stock.
Thanks for your reply

[Q] Tab S dead all of a sudden

Model: Tab S T805M (that's the 10" with LTE) rooted and stock firmware. I've had it for over 6 months and nev er had any issues, ever!
Yesterday I fully charged the battery using an original Samsung charger (from my late Nexus 10) until it was full.
I then used it for a while (basic stuff) then installed a game (Hill Climb Racing), played for a bit, then let it sit on the coffee table. Naturally, it went into sleep mode. Once I tried to turn it back on, about 30 minutes later, it was dead.
It doesn't have a SIM nor micro SD card in it.
I tried the key combos to get into bootloader or recovery, no go.
I tried holding power button for several seconds, no go.
I tried connecting the original charger that came with it, no go.
I hooked it up to my laptop, the same I had used to root the thing months ago and has Odin and all drivers installed and everything, no go. It won't even acknowledge there's some USB device connected.
Then, for some reason, while still connected to the laptop, I was randomly pressing buttons on the tablet (out of mild desperation, I was tired, just wanted to get it fixed and get some sleep) and I saw the battery logo again. It was at 99%, the way it was wen I last used it. So I unplugged the tablet and booted it normally.
Then, again, I used it for a while, connected to my WiFi, everything normal, and once it went into sleep mode, it died again. No buttons, no USB, no response to charger.
So, the problem is repeatable, but I haven't figure out yet the exact procedure to bring it back from the dead.
I'd like to fix it, even if I need to flash the stock ROM back on and lose root. If that's impossible, I'll settle with a tip on how to reboot the stupid thing once it enters this state. Then, eBay, here we go.
KNOX was tripped when I rooted, so I guess I can only try my luck with the warranty.
I think you should start your post letting people know that you have rooted and flashed your 10.5" and not in the last three lines.
Do you think your battery level is being reported correctly, as if your tab thinks you have 90% left when you only have 50% , then you game and use 50%, and think you still have 40% left but when your battery hits 39% it will just die, no battery warning or anything.
Flashing a tablet can cause the battery to be reported incorrectly, since you are rooted, download a free battery calibration app off the play store.
You say you have had your tablet 6 months, if you game or use other apps that rapidly drain the battery, the battery might be failing.
Since you say the fault is repeatable i would have the tablet replaced, flash it back to the stock rom and remove the root, Can you reset the KNOX counter, I think i read you can somewhere on this forum.
Good Luck

Yes, I did mention in the FIRST line I had a rooted device with stock ROM.
Tonight I was just able to enter bootloader and stock recovery and did a data wipe / factory reset. Let's see what happens now.
I'll install a battery tool to see what's really going on. Maybe my battery is ****.
GSam is the battery monitor i use, have a look at the alarms in the setting, I have them all set, I got a high temp alarm while my tab was in it`s case while i was asleep in bed, I remove my tab and the back was hot, just shows what can happen when you think your tablet is sleeping.
I bought my 10.5" before Christmas and it has never been turned off or rebooted, I have about 170 days continuous use in the battery settings, so it`s been quite reliable for me apart from that little temp hiccup.

Phone won't charge, also I think it tries to turn on by itself

Hello!
My phone suddenly stopped charging... and now it is dead... now... like every 3 or 5 minutes, it vibrates by itself, even if unplugged... Anyone heard of this issue?
More info in my last post:
I'm unlocked, rooted, xposed, installed Beanstalk ROM, etc... But I did that months ago (I don't know, 6 months ago?) and it has been working flaglessly, I didnt do ANY change prior to this problem (really, no changes, not even a new appp installed or removed in months)
So I really think it is something in the usb charger.... Maybe I'm wrong and it got bricked somehow... please validate that.
Also, it still vibrating at least once every five minutes. (I woke up all night with it vibrating and now it is on my desk and it still does it)
I just tried an adb wait-for-devices and nothing happens, also tried to reboot it the same way and nothing happens.
Now, I remember that I did something before the phone turned off (battery ran off) I deactivated an Xposed module (latalysm or somethign like that) and didn't reboot it to complete the deactivation. Maybe it has something to do with 0% battery and that?
I really don't think so... But your advice is really welcome.
Thank you in advance.
Did you rooted or unlocked?

New data:
When I pluggin the phone to the PC, the PC plays the "hardware detection sound" but then it disconnects too. Maybe it has something to do with the battery or something related?
Thank you in advance, phone is still dead.

Well... my phone is now even more dead... I think the problem is the battery, even if I try to charge it doesn't even get warm, I replaced the usb piece of the phone expecting that it was something with that but no... Now I'm waiting to get a replacement battery.
Anyone heard of the same issue? I've found many people having the same issue, but most of them solved the problem unplugging the battery and then plugging it back again.
Please help!
Regards.

I have exactly the same problem. It's like the phone is not charging at all. Have you tried taking the battery out and then in?
Small update: I've tried 4 different chargers and god knows how many different cables, tried connecting it to the PC, nothing seems to help.

Yes I tried that 2 months ago... But yesterday... I arrived home and tried to charge again, waited about 2 hours, turned it in and pop... I have the phone again (I keep losing phone and data signal, but... come on, it is on now)... So I don't know... I heard many times that pluging in and off the battery and "waiting" seemed to work for a lot of people, but come on... 2 months?

That is a lot... I waited 2 months... sorry I don't know anything about the matter... but don't lose faith, maybe it will turn on again someday.... Advice, charge it and leave it charging for... a week? then try again.
I've decided to fiddle with a needle inside the USB charging port recently. After that my phone suddenly was recognised by the computer and started charging and working. After I connect it to the real charger, doesn't matter if it's original or not, it stops working and doesn't even charge from the PC. Then I have to fiddle inside the charging port and everything works again... wtf really? what can be dead?

I'm not so sure... It sound's more like I'm either grounding some contacts or I'm somehow short circuiting something. Maybe it could be a broken capacitor or something? That would explain why your phone started working after 2 month.
Well in any case it would be interesting íf somebody with that issue would try touching the contacts in the USB port with metal needle and connect the phone to the PC.
I've ordered a new USB thingy already and going to swap it soon, I'll keep you updated.
I have try to change the battery and the usb port. The battery work one time but won't charge. Can't say if it is the same issue or because is is a cheap battery
Any news NiKiToS?

My friend is dead:( SM T800 random boots

I don't know what happened, but my true friend is probably deadly ill and she's dying.
My Samsung Galaxy Tab S 10.5 after almost 3.5 years of really hard work, 8h daily of SOT, hard CPU tasks, loading battery two times a day, started to do strange random reboots.
I was installing Blue Filter app, reading big pdf and sending this PDF from Xodo to Voice Aloud reader. Tablet was connected to charger from Moto X Style, which is turbo power charger. I saw first reboot, then other and next. Entered Cwn Twrp, cleaned cache but the problem still existed. Cleaned system, internal storage and tried to flash Iron ROM again. Strange, but tablet couldn't flash Iron ROM 3.2 gauge showed 100%, almost after beginning of installing ROM. I decided to flash 4 elements repair ROM with Odin, but it didn't help. Checked erase NAND, flashed correct pit file.
Strange, but while flashing with Odin, there were no reboots, so downloading mode is working properly. But after install, reboots returned, almost after running system first time.
Maybe it depends on ROM version? I flashed 4 files of 4.4.2 with Odin, while I was on 6.0.1 earlier?
But reboots started on proper ROM.
Also, maybe charger is responsible? Moto X Style 3A charger maybe damaged memory or motherboard of my friend?
Do you think that exchanging the battery may help? My battery when it was loading frequently showed a red cross, it can be that it's damaged, but random reboots never happened to me.
I don't want to buy new device, it's really stupid for me to spend hundreds of dollars every two, there years. I believe that a device should work 5 years or longer. Maybe corporations make devices especially to die after warranty period?
Can you help me to determine what is damaged?
It was my true friend, carrying tons of books with a thin device, reading big pdfs smoothly, making notes tons of paintings, editing photos and taking photos with my Nikon D610 via USB, listening to music with A.r.i.s.e , watching photography tutorials and movies, modern Combat 4 tons of hours, notes, showing portfolio to my clients... Yes I love my small friend, can you help me to rescue it?

Are the reboots happening even while plugged in or only after unplugging the charging cable?
Also is the percentage reading being sporadic meaning it changes every time it shuts off?
Replacing the battery is fairly cheap and easy on this model.

If for some reason it still has the same issue after replacing battery then the battery connector needs to be looked at under microscope. It may have a loose connection to the board meaning it would need to be resoldered.
Dear Benjamen, thanks for your help. Tab reboots even if it's plugged to charger. The percentage is strange, one time it shows 40%, another time beeps and shows low power warning.
Sometimes it works 5 minutes without reboot, some times boots many times continuously.
Do you think it's battery? No EMMC error or some chip damaged on motherboard?
Download mode Odin worked good, also CWRP worked without reboots.
Maybe internal storage is damaged?
What do you think?
If it is battery I can surely exchange it like you wrote.
You can see the behaviour of tablet on YouTube I've posted above.
Have you tried to reinstall Twrp and a custom rom besides Iron Rom and doing a clean flash? Also I was thinking it might be a corrupted sd card try to remove the sd card and reboot see if that works I had a tablet once that was going bonkers cause the sd card was messed up , it might not be it but could always try it. Also make sure your on the proper boot loader for the rom you are trying to flash iron rom thread actually has a link to all the current boot loaders if i remember correctly. I do own this device and run a custom nougat rom no issues, just shooting out some ideas but you are right this is great device and should last a long time.

Sounds like battery connector has loose soldering. Take it to a reputable repair shop that does soldering and tell them to check the battery connector and see if it needs resoldering. That's how I ended up fixing it with the same symptoms that you had.
Edit: Forgot to tell you but I cant play the YouTube video, maybe the embedded video link is invalid so can you send me the youtube link?
Mine has been doing the exact same thing for a couple of days now.
I'm running LineageOS 14.1.
Random reboots both with the charger connected and disconnected, Battery percentage is around 45% most of the time, but jumps to 0% or 100%.
I've already replaced the battery with a "new" one (about 12 months old, according to the label), but to no avail.
Any ideas? I really like this device and would not want to buy a replacement...

My SM-T800 started doing something strange like this yesterday. As I was watching Youtube and reading a news site in split screen mode, the screen suddenly went blank (it didn't shut down, but went blank at once). Before this happened, I saw a warning that my battery charge was below 15%. After powering on the tablet, my charge was 28%. I opened youtube and a web browser again, and the screen went blank within a minute. After powering on, I decided that I will not be using split screen mode again, but the screen eventually went blank. I monitored the CPU temperature and it didn't seem like it was running too warm (50ish C). I will try re-calibrating the battery (if that's even possible) and even replacing one, but if that doesn't help I guess it's time to move on to something new. Sadly, four years after the T800, nobody made a worthy replacement (the leaked Tab S4 specs look good, but they want to charge laptop prices for that).
PS: It's running the stock rooted (later unrooted) MM 6.0.1 from November 2016 with TWRP.
I re-calibrated battery and the tablet seems to be working fine so far.

Okay first of all very big thank you for your replies
my Galaxy Tab S 1 except strange reboots is also overheating when it has some tasks to do measured temperature on CPU cores is getting around 80 degrees Celsius and is going up and then tablet gets restart so I don't know if it is only the problem with battery maybe it's connected with CPU problems or other electrical problems on MotherBoard.
It's worth to mention, that I've charged the tab with charger from Moto X Style, that is Turbo Charger, with 3A, and the Tab S1 can load with 2A only.

My tablet used to have a damaged main-board that used to overheat. However, the screen did not go blank when that happened. I actually got some kind of message that said that the tablet is overheating. This was fixed after I replaced the mainboard. You can certainly try it, but these things were not cheap when I did it.
Mine also started doing this last month now it wont power on but resets till the battery is dead.
Did you get it fixed?

I'm seeing random shutdowns with no warning popup on heat but the screen area where the motherboard is sure gets hot. I replaced the battery and same result. I looked at the battery connector and looks OK, seems tight but I didn't check with a magnifying glass. Where did you source your motherboard?
Also how has everyone elese resolved this? I see people citing the problem on this old thread but I'm curioius if you found a resolution.
