[Q][HARDWARE] I need to replace the Power IC. - Galaxy S3 Neo Accessories

So, i realised that my s3 neo's power ic is damaged, proof : it charges/discharges in very very short time, and sometimes the screen flickers and the battery die directly and i have to connect it to the charger to switch it on. I got a recommendation to replace the power ic, and i heard that this board is not using the same power / charge integrated circuit as the Exynos S3, also, I've found only for Galaxy Grand 2 power ic part which is the PM8226. my question, where can i get this part and is it the same as GGRAND2?

Well thanks I've just disassembled the phone and i found that it has the same power ic as galaxy grand 2 and redmi 1s (pm8226 12)

Look for broken phones. This would be the fastest way

[Q] My Galaxy Tab 3 10.1 (GT-P5210) Just Turned Off and It Won't Turn On again :(

My Galaxy Tab 3 10.1 (GT-P5210) Just Turned Off and It Won't Turn On again
I thought that it was due to the low battery but now that I'm charging it, it wouldn't even show the battery thing being charged
I didn't root it.
Please help me!!!!!!!!:crying:
Hello, same Problem here. Did You solved it?
How did you charge it? I had the problem while I charged it on my PC.
I solved it: Let him charge with it's battery charger for an hour or more
A computer USB port is not powerful enough to charge this beast. Make sure you use a charger rated for at least 2A like the original.
Samsung Galaxy Tab 3 - 10.1" [GT-P5200]
My Galaxy Tab 3 - 10.1" [GT-P5200] has also turned off and does not charge anymore.
Tried with a couple of original chargers but it just would not respond. It was also not rooted nor flashed.
What shall i do?
And mine doesn't work at all on battery, like it is not connected.
My P5210 works only with charger connected.
Anyone had this problem?
It started with when I pushed the power button, it just went dead... disconnect and connect the battery and the Tablet came back to live again. And now when I plugin the charger I see a empty battery image, the a blue full battery image and then I push the power button and the tablet turn on.
When I remove the charger the tablet dies immediately.
End of live of the battery?
I guess I will open it to take a look inside again...
Opened the tablet and firmly pushed on the battery connector and it works again
Sent from my GT-I9305 using XDA-Developers mobile app

Samsung Tab 3 8.0

Hi All,
Could do with a little, well rather a lot of help please.
Go a tablet that wouldn't charge, therefore I have replaced the battery with a like for like battery. Also I have replaced the USB charging port. I have followed lots of on line tutorials about unplugging the battery and holding power and volume buttons etc. These have not worked and I am now at a loss, so any other options I can follow before i finally give up saying its the circuit board.
Thanks

which part is wrong in my e988 ?

Before flexible-homebutton-softkeys-charger port part replacement :
1. Battery already swollen
2. Home button unresponsive most of the time
After flexible-homebutton-softkeys-charger port part replacement :
1.home button still unresponsive most of the time
2. Charging the phone only reach 15% max, then it goes down to 14%, then goes up to 15% again in infinite cycle
3. Had to use external battery charger in order to get the battery charged to 100%
Which part in my e988 is the real source of this problem ?

I had similar home-button issues with Galaxy R after DIY screen assembly replacement. Can be button having bad physical contact with board (manifested by dropped button, short clicks, hard button or even too soft button; button has to be in level with front panel glass and has to be soft-ish, but shouldn't get stuck or too hard to press), can be board's bad connection with motherboard - check that micro connector, it maybe didn't fit properly or there is possibly some dust in it (this was my issue with Galaxy R).
Battery one is probably connected multiple factors, including broken battery, because I think that charging electronics in E988 won't allow charging of broken batteries on high currents - mine didn't even want to start with broken or replacement batteries without temperature sensor (so had no luck finding good replacements - funny enough, friend with F240K could use all of those). Capacity reading can be also false (but if battery is charging with powerbank, but not with charger, small chances for that) - you may want to check what dmesg reports - it gives constant battery percentage and voltage updates during charging, and also check Ampere measurements while on charger to make sure device actually has some juice coming in.
Last idea was from experience, I've connected mine (while it's pot was 100% functional) to a friends cable, device charged up to some percent (maybe 20%), and started playing same game due to really low charging current it was getting from that cable. Back then I didn't have Ampere, but I was accustomed to things like that from the begging, when my brand-new E988 didn't want to charge on Samsung and Nokia cables Had to trade some really nice and long Nokia cable for crappy LG's one longer than 50cm because of that...
P.S. How did you get that part all in one? Isn't home button/softkeys one assembly, and USB/OTG/MHL/Charging another? Or my old E988 somehow differs from yours. I'm looking for charger assembly because I gave my phone to a family member who asked for it and knew about a problem, and they are already whining how "it works only with one cable and I can't use phone while it's charging!"

This is the part, which I bought online
Yet, it still doesnt fix the problem, is it possible that the IC chip on the board is the real culprit ?

I'm pretty sure my USB board looks like one from the attachment, without all that plastics around... I may be wrong, though, it was long time ago I've opened my device, and I can't really grab it now and open to check out.
As for the IC, chances for that are small. Have you tried charging with other cable/charger pair? If buttons aren't working you can always use on-screen ones, but port is a greater issue.

That plastics are the softkeys, and in the middle are the home button and micro usb port
Tried many cables, all give the same result

Note II cant tutn on. Bad power ic?

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

Red led of death

Hi all, my Nexus 5x wont charge but Red led is blinking and then nothing happens, I broke the originale LG type c cable and I left the phone discharged for 5-6 days until the new cable come, and now It wont boot nor charge with no cable or Wall charger combination, searched on web and found people saying to let It in charger overnight then try booting and similar things but nothing is working.
anyone here got this problem?:crying:
Hi, I had the same issue... and charging overnight will not fix your problem....
it happened 5/6 times to my phone, the only way to make it works, was to pull out- pull in the original charger, and after 10/20 times you do this, it will work again.
I bring it to LG assistance and they told me that sometimes, all the updates and the full memory (mine was not full, but 17gb over 32) made this. I didn't believe that, BUT an hard reset of the phone and it never happened again in 3 months
Hope it will work for you too

Thanks, I will try, but how much time do I have to wait before pulling out and pull in again the charger?
Can anyone help me please?
I had the same. I forget about phone and left it with TWRP running. It drained all my battery and phone wont turn at all. I had this same red LED, so i plugged phone to charger and after maybe 2 hours it turned back on (charging screen), wnother hour and my nexus was fully restored with full charge.
Also i recommend you to get original charger and original usbc cable. Also before it you can hold power button for 30 sec. In some Xperia phones even a few days can do a trick.
Finally understanded the problem Thanks to "Dusan Milanovic"
In my case it was:
- 50% Battery problem
- 50% Qualcomm Power IC Chip
How I solved it:
I AM NOT RESPONSIBLE FOR EVERY DAMAGE YOU MAKE TO YOUR PHONE, HOUSE, GRANDMA.
REQUIREMENTS:
- Alluminium foil (biscuit metallic paper) not plastic
- Hairdryer (It seems stupid ahah)
- Chronometer
- Attention!
- A bit of patience
BATTERY PHASE
- Open the Phone and remove Fingerprint board.
- Remove the Battery.
- Put the battery on an universal charger.
(do this only if you are sure that the battery is discharged and don't want to charge)
Let it charge for an hour more and less.
POWER IC CHIP. PHASE
- Remove the metallic protection between the camera and the battery slot.
- Look for a black chip surrounded by little grey chips. (POWER IC)
- Protect everything in the motherboard with the Alluminium foil except for the black chip.
BE VERY CAREFUL, PROTECT EVERY SINGLE GREY CHIP NEAR THE POWER IC CHIP.
-Prepare the Chronometer 1 minute.
(NOT MORE THAN 2 MINUTES OR YOU MAY SERIOUSLY DAMAGE THE MOTHERBOARD)
-Use the Hairdryer to heat the POWER IC CHIP
(DO NOT USE HEATGUN). The chip needs to reach around 100°C
-After you heated the chip let it cool down for a minute or two
-Remount the metallic protection.
LAST PHASE
- Put the battery on the phone
- close everything
- Try to boot it
ALL DONE?:highfive:
POSSIBLE PROBLEMS
- always shows 100% battery. → buy a new battery( this one is Dead)
-Doesn't boot.↓
→Are you sure your battery is charged?
No: charge it externally (BE VERY CAREFUL THIS COULD BE VERY DANGEROUS)
Yes: then try to heat again the POWER IC CHIP (2 MINUTES MAX)
→Still nothing?
- Buy a new Battery, this is the best choice.
- If even after you use the new Battery the Phone doesn't boot , just heat again that pain in the ass of a ic CHIP.

When phone turns on backup your files when you are in time

HARD RESET instructions or link you followd that worked drop below
I just had the same thing happen. Using the original charger I kept on charging then trying again and again. I would leave it overnight unplugged from the charger. I think the battery was draining due to screen not coming on but phone booting over and over. Finally after about 6 times, I saw a battery symbol, then pressing power it came on as if everything was just fine.
I found another way, though be careful. Repeatedly unplugging/replugging did not help. Disassembled phone (lots of guides), unplugged battery. Measured 2.96v - too low for lipo. Used lipo charger (100mah) to boost charge to 3.2v. Reassembled, and it charged OK.
Cause is probably voltage dropped below the low charge threshold for lipo charging cct onboard. Lipos are very tricky to charge - lots of papers on this. In theory Nexus should have shut itself down before voltage dropped that low - but it didn't. Design flaw.
i had red blinking but battery was empty.
since in bootloop it will not charge, after i repaired reflow and patched the boot
to 4 core it worked perfect.
so if someone comes here and wonders, it might not be the charging chip
just the battery empty
