Note II cant tutn on. Bad power ic? - Galaxy Note II Q&A, Help & Troubleshooting

Hello, please i need help. My note 2 cant turn on after rebooting. When i conect it to charge, LED charging indicator not working. Phone is completely dead. Problem is in power ic chip? Can be data restored when i replace ic chip on motherboard? On aliexpress i see for note 2 small power ic and big power ic. What is different between small and big ic? On motherboard can i found two chips - smll and big power ic?
Phone is old, but i need data on internal storage.
Many thanks for response.

Try removing the battery and charger, hold the power button for 30 seconds, then replace the battery and try charging the phone again. . Same thing just happened to me today

Thanks for your answer, i tried many tricks and i tried yout trick but its not working after 30 seconds without batery and charging, phone doesnt working phone is still dead

I would like to know too, mine gone ice cold just like that. I do remember my battery was fully charged, then the next day can't power on, no signs of charging when plugged. Did everything I can still no signs of life....

I think it is SDS (Sudden Death Syndrome)
and it is related to EMMC ( bad internal storage ) , so maybe in your case it is not IC power problem
so before you buy any thing , you should ask service person to check your phone

as far I know
when the phone (note2 ) stuck at this point (black screen)
it can be checked via power supply ( service center ) in order to test how much AMP needed to power the phone, so they can decide if it is [[ battery issue or IC power or EMMC.....or other thing
so you cannot go far and buy parts for your phone before you ( or asK) an expert

Ok thank you

by the way before you judge you can try this
in some cases ( black screen ) can be restored via JIG to access to download mode
then you can try to flash the correct firmware to your device via ODIN

Dead Diamond

After a long phone call, about 20 minutes or more, my diamond was too hot and suddenly died. I was using v1.09.25.23 radio, and the latest GR rom cooked by swtos... Im not able to hard reset it, or enter the bootloader. the battery is able to charge. when i turn it on, the device is ON for about 4 seconds and turns off again. is it bricked? any ideas?
imho i think the battery died
bootloader = NOT bricked

Going on what information you've supplied regards how the diamond's acting m8 I'd have to agree with him there, it sounds like your battery is'nt holding a charge.
If the phone turns on normally then switches off after a few seconds it's more than likely a power issue.
Try a DIFFERENT battery (even a mad cheap ass'd 1 off of ebay if you can't get a hold of 1 elsewhere, 5 euros ) before you do anything else.
If the OTHER battery acts the same after it's fully charged then you may have a probem with your diamond's power stage (that heat you mentioned might have caused damage) & you might have to deal with returning it to warranty etc...
Hope this helps & GOOD luck
thanx guys! after all night charging i managed to enter the bootloader!
It's alive!

[Q] WTF Happens. It's Dead.

Hi people . I'm desperate.
I have a Tab S T800 and i still did not know what happened .
I turned off the tablet and when i cam and get it to turn it on again ... nothing happened .
Since , i tried everything to turn it on .... All the combinations of buttons and etc. Home + Power + Vol up , Vol down + Home + Power, Power + Menu touch button, Plugged on PC , unplugged , on the original charger , on a parallel charger .....
And NOTHING has happened to the tablet ... the screen is black .... and the tablet did not fall , did not got wet , did not got overheated ....
What Could i do ? I have very important data in it and i can not lose ... The tablet still under warranty ....
I appreciate all the help.... and i already looked on the forum for solutions...i didn't found one at least that works...
Thank you all.
Sorry for my bad english...i'm Brazilian.
Nhave you plugged it into a wall charger for a good hour before trying to turn it on? Make sure battery has some charge.

Try home+power+vol up+vol down and hold it for 1-2 minutes or until something happens? Try it also while it's plugged in.

Does it still connect to a PC? If so you can back up all your data if it still connects

It's attached, but not connected...if you know what i mean...
Pc didn't recognize the tablet... Tablet is completely dead.
Which of the steps suggested have you tried? in terms of holding the power + vol up + home button?

1. Home + Vol up + Power.
2. Home + Vol down + power
3. Home + Vol down and Vol up + power.
4. Menu Touch button + Power.
And i did all this connected on PC, Disconnected, Connected on a original Wall Charger and on a parallel wall charger.
Do you even get the noise on the pc to detect that something is connected?

Hi Gustavo,
Sorry I'm new member but may be able to help you with this.
I had a similar experience with my son's tab 3 kid's edition last year.
It just died and wouldn't turn on. I tried everything but no luck. I then decided to take the tablet back to samsung store and packed it. I was suppose to go the store 2 days later but after 48 hours of device dying I just thought of trying to turn it on and plugged it in to the wall charger.
To my surprise display came on showing red battery icon and after 30 mins approx, device showed green battery icon still charging. after roughly 10 hours I turned the device on and it works flawlessly since then.
Hope this helps.

Hi! Thanks for the help! But before i make this topic i waited for 3 days to put tablet on a charger.... nothing happened =/ But i'm gonna try again!
I had a similar problem.
Do you know how to separate the screen from the body? I found that the connector at the base of battery was very loose. I managed to push it down and it turned on right after.
Hope this helps!
Whilst I agree it could be a loose connector, it would void your warranty. I would see about going to your local samsung repair centre and see if they can have a look without wiping.
This happend to my 8.4 last week, no way to revive but i can feel warm at the back while doing all the first aid trix but no luck. So i decided to bring it to the nearest samsung store w/repair service they remove the back cover and battery, they told me they just ¿¿refresh start?? the battery? because it was drained!!?? wtf i remeber i left it with 30% charge... but anyway they fixd it in less than an hour. But yesterday the symptom returnd again i have to power+down+home just to turn it on :/
Plug in the charger then press power + vol down (not up). Hold for a good while until it restarts.
If it doesn't then it could be hardware related.
With so many people reporting battery problems, you might just have a bad battery and that's why it gets hot when connected to a charger. *I* would open it and check the battery's connection and maybe even replace the battery.
I saw some videos...but i don't want to void warranty :/

As Nexus stayed blank, i thought it was battery , i change it without help.
when i put it in charge nothing happend. no white led nothing no screen
i tried the power + vol - reset ... nothing.
The only thing that i think it isn't completly dead, when i connect the device to Win7, a device appear in ports under device manager
forge hs-usb QDloader 9800 on port com 9

Any reaction during charge: increase of temperature of charger and/or Nexus?
I changed the battery. the new one was charged / i had checked the 5V output .
do you mean that i had to check if the charger temperature is raising during charge ?
It seems that your Logic Board ( = the board with the RAM, SOC etc. ) is fried. The good news is, 16GB boards are still easy to obtain and also easy to replace.
Ebay still has plenty of those while 32GB boards are harder to get.
Thanks you .
Do you know how i can be sure of diagnostic ?

LG G4 doesn't turn on anymore ( H818N)

Hi all,
My LG G4 doesn't turn on anymore even while I am charging it..
I am actually travelling, I suspect it does come from a high voltage when I tried to charge it in a bus.
At the beggining I tried to put the battery off the phone, first the screen with logo for few seconds and after black screen. Now only black screen.
When I try to charge it , nothing happens.
1st question : do you think that a hight voltage can break any other spare parts of the phone ? Do you think the battery can be a fusible ?
Where I am , I didn t find a LG selling point so I cannot try with another battery for now.
My phone is not under warranty anymore.
Do you think that this troube can be repaired in a common repair service center ? ( not LG )
Any advice except waiting to find another battery ?
Thank you guys !

The simplist thing to do is check if the battery is charged and working. Check the serial number on the back and reply with the first 3 digits here. It is likely that you have faulty phone that needs to be fixed by LG (if it is still in warranty)
If you're sure your phone isn't a faulty model, try to enter recovery mode.
1. Hold down the power and volume down button together.
2. If the LG logo appears, continue holding the volume down button but let go of the power button for 1 second. Then hold it again.
If you get to a recovery menu, there is hope.

Thank for your reply.
With my current battery (as I still didn't have the opportunity to try to change it) , I can't even power it on (no logo even while try to enter recovery mode)
I will try with a new battery and let you know !

Poco M3 does not turn on anymore ( Solution / Fix )

Problem with this phone the new update xiaomi original rom / kernel discharge battery to 0.00 V ( i measured it with multimeter ) and you cant charge phone and thats why you cant turn on this phone anymore .
But i found the fix
Steps :
1 . Just dissasembly the phone
2 . Remove the battery from motherboard
3 . From backside of motherboard remove metal plates from the chips the CPU heat that side for 2-3 minutes with hair dryer when you dont have heating gun ( I was inspired using hair dryer in times of iPhone 4S wifi / signal problem )
4 . Put every parts back with battery plugged on motherboard
5 . Put the charger to your Poco M3 and turn it on
6 . You are done let phone charge to 100 % and remove that crappy Xiaomi ROM named MIUI and install any rom what you like .
I know its stupid fix but its working . I dont know its permamently damaged IC charge chip / CPU chip because of kernel / rom new update but its works for me fine for now .
Update : you need change PMI632 902-00 chip and it will fix you this problem
so after doing this you can reboot or have it shutdown lets say using a custom rom?
Hi. I encountered this problem with my phone but I don’t have the skills and the equipment to disassemble my phone so I tried other solutions.
I wait for days until the battery is completely discharged. When I plug it to charge, the screen turns on again and it begins charging again, initially showing an empty battery icon. Before unplugging, I check the battery percentage. If it’s at 10%, I wait for the screen to turn off again and then unplug the charger. The screen turns on again and I press the power button and my phone is alive again. These specific steps are important as well as timing. I had failed a few times so I had to wait for the battery to discharge again to retry. Hope this helps someone else.
But I have another question and I hope it’s ok to ask here. Is this a hardware problem? I was thinking it was a software problem so I was planning to root my phone hoping to not encounter this problem of my phone suddenly not turning on.
