GALAXY Note 4 SM-N910H 5.1.1 Superheating - Galaxy Note 4 General

I have updated to Android 5.1.1 Stock version hours ago and it has two big problems:
1- It has the superheating problem so bad that I could fry eggs on it.
2- It super buggy and slow nad sluggish. It hangs when you want to move between the pages.
Also, I don't know why but I think that everything is super bright and it hurts eyes.

did you do a clen install? or a dirty one?

Factory reset will fix you're issues

Not for me. I did not do hard reset but everything is working fine.

Still downloading here. Will let you know how it works out when I get it installed.

Here clean install on 910f no problems. Works great finally. Everything fixed, just ram agresion stayed

I have the N910C and same thing happened to me.. i did everything i know but my mobile dont cooldown.. everything is hot, the screen, the sides, the back.. i check the temp using cpu-z and says 43-45° only.. i downgraded to 5.0.1 but still the problem is there. Then i decided to show it to a technician.. he also found out that if i take out the battery and turn on again, it wont turn on unless it will be plugged to a charger.. he said that the power IC was damaged and it is a problem of a lot of note 4's. I dont know what to do anymore. I already lost my warranty due to rooting.. please any help?

Ask the technician to remove the broken PMIC (power management Intergrated Circuit) and replace it with a new one, he probably has the skills and tools to do it, i also do it at our shop, it's not that hard. And it would be a pretty cheap repair too since the cost of those chips is usually around $5.
Or you can try brick it so it does nothing at all anymore and send it for warranty. If it's dead they can't check your knox status.

Finally, i got hard bricked...

Hello. Sorry for my english.
I've been living on the edge, like many of us LOL, and i finally got hard bricked. No battery charge, logo, download mode. Nothing. Just a black screen.
I was using ICS stunner 1.4.26 and decided to flash Catastrophic Meltdown 9 (CM9 for friends). The problems was that my battery died when it was installing the kernel, or the boot, i dont know.
So, i have been reading a lot those days but nothing seems to work. I have ordered a Jig but i think is not going to work. Yesterday i used windows, and something was detected when i plugged in the usb, but Odin not.Today it does not work, and windows doesnt play any sound. Any idea? A Jag?
I should say this is the best mobile phone i have ever touched. I would be eternal grateful with all of you if we could fix this mess. I was aware that there were risks. Im aware now maybe i cant fixit and im not gonna blame anyone because it was my responsability, but any help would be appreciated. Thanks.
Same thing happened to me, nothing worked (tried the JIG). I had to send it in for repair, but they didn't see that it was my fault (still had warranty).

From my experience the only way u can get ur phone back in service is go to ssc and make some reasonable reason why ur phone is dead, so u can still claim for warranty and I am sure they will replace ur engine/mobo like my friends did a month ago.

It has nothing to do with your battery dying and everything with trying to flash CM9 directly from super-dangerous LP5 or LP6 leak ICS kernel.
No jig or JTag will revive your phone now.
However, if your Note refuses to go into download or recovery mode, you are in luck - if you have a warranty, that is. Just take your phone to the service center and tell them that it died when updating via Kies. There is no way for them to tell what had really happened and they will have to replace your motherboard free of charge.
Sadly, jig didnt solve the problem. Battery isnt hot when plugged in, is my motherboard fried by flashing the note?
Could a jtag solve the problem?
Try to take it back in for warranty before attempting a JTAG and voiding the warranty (that they can tell)

Yeah, that's a classic superbrick, need replacement mobo. Sorry dude. As mentioned just say you were updating ics ota or through kies.

I got the same problem few days back..I went to service center and said that i got an ota update and after downloading had completed,it started rebooting and there i got some errors and finally my phone is dead
They were unable to find the exact reason why it got bricked as it was unable to enter download or recovery mode
So they replaced the motherboard under warrenty
Better this it once
All the best :good:
I dont think that warranty thing is gonna work, because i have lost some inside cover screws... yeah, thats a long story trying to fix it. If i borrow a motherboard... could i recover my data? because thats all i want at the moment. Or, is there any website where i can buy it? Otherwise, im going to try it with the warranty...

I just came back from the service center and they are covering it under warranty . Similar symptoms and they are going to replace the whole board. Just take it to the service center and say "Yo man your **** died on it own" :fingers-crossed:

[Q] Samsung Galaxy Note N7000

Hi everyone,
First off, my samsung galaxy note n7000 has a strange battery problem. It charges really slowly in the wall but seems to be faster in a pc, and when it finally gets to 100%, I get the notification that says 100% charged; so I unplug and it quite literally jumps to; 1%, 67%, 84%, 15%, it differs everytime. Ive tried a factory reset and wiping cache paralition, nothing has worked. :crying:
This brings me to my second problem, a few months ago I dropped it whilst working(I'm a farmer, which explains why I dont know how to fix it) and the screen glass smashed, but the touch screen works perfectly however if I take it back to the store, will it still be under warranty? Ive only had the phone for six months.
I have tried numerous chargers and batteries, doesnt fix the problem. If its not under warranty, would it be worth waiting for the official samsung ota update to android 4.1 jelly bean, or will the problem carry over.
I hope somebody could help me with this problem and give me advice about whether I'm covered under warranty. Thankyou

Dear kylegriffies,
First on the battery problem, I can think of two possible explanations: 1) the battery aged, you need to change a new battery. But as we have seen you had down it before, so it must be a phone hardware issue. 2) There is a damage in some voltage detection unit, maybe a water damage or something that made it short a little bit?
For your the screen damage, that is an accident I guess. If you have insurance for accidental damage I guess you can fix it, but if not, the screen is not under warranty. Try to ask them if they can fix the circuit problem.
The best way I suggest is taking it to Samsung service center regardless if you have voided the warranty. Sometimes for luck too.
P.S If you work in the farm, I recommend a Otterbox case(if you get your screen replaced), so even if you drop them it's not likely to be damaged.

thanks for the reply
yeah bought a case as soon as i smashed so it never got worse and i dont have insurance unfortunatly... however, even if my screen is broke, will they still fix my battery problem? if it was a hardware issue... how could i resolve it?
cheers
Samsung will change it in warranty. I see no reason since battery related unit and screen is pretty irrelevant.

[Q] Is it lost?

I dropped my galaxy GT-I9100 in water during my vacation. The next few hours all function returned and I used it for a full week. When I returned at hom I re-flashed the phone with I9300_Omega_v45.1_XXUFME3_md5_2588F4A59718C762E44E5DAE8C3380EB.zip Then almost nothing worked any more. It is stuck in boot. No recovery mode possible. Downloadmode is working (on screen in this mode: Odin mode, Product name: GT-i9100, Custom Binary download: no, current binary: samsung official). But it is not possible for me to connect with the pc and use Odin. Tried different cables and PC's.
In despair I brought the phone to a repair centre. They gave it a treatment against moisture. But they could not connect to the PC either. Even after renewing the USB port. They gave me the advise not to send it to Samsung because of the waterdrop. (to expensive).
Is it lost? Or ........?????
if someone here drop their fone in some....water, MAKE SURE take out battery n etc n dry it completely first (exactly one week without booting) to make sure board completely DRY before using

Wait, just to clarify,
So
1.) You have an I9100 (Galaxy SII)
And
2.) You flashed Omega rom (which is a Galaxy S3 rom)?
To help with the water damage, if you removed the phone immediately it should still be fine. Take the battery out, wipe down what you can with a towel, leave it for some time to dry. Put it in with some rice for a day, the rice acts as a moisture absorber. See if that fixes anything. Worst comes to worst, tear down the phone and check the water damage indicator. It should be a little coloured strip behind the internal back cover that turns pink (I think?) when water damage has been detected.
Although... If you flashed a rom made for the S3 onto the S2... Unless the same zip can be installed on the S2 maybe the problem doesn't lie with water damage at all...

1) Yes
2) Yes
I immediately removed the battery. Wiped it. And let it dry in the Israelian sun (on vacation). All functions came back and the telephone worked fine. At home (after a week) I flashed the wrong Rom and the problems begun. The repair service has given the phone a anti moisture treatment but didn't succeed to solve the problem of the wrong Rom

Yeah, this can happen when you try flash a rom specifically for another device... There have been cases where the phone is killed completely...
Water damage, if treated quickly enough, won't affect your phone too much. One time my phone was half-submerged in water, with the microphone end in the water. Screwed up my home button for a few days, but now its fine.
Your problem here is flashing a rom for the wrong device (I thought the SII had its own version of Omega? Could be wrong). And that leads to much more serious problems.

XSP spontaneously turning off

Hi guys,
I got my XSP 17 days ago and it's already giving me this weird problem. I bought it brand new (well, I got it from a possibly shady reseller in Russia, but it looked new and un-tampered, I checked it carefully ).
It worked perfectly as my main phone for about two weeks (with the official stable CM 11) when suddenly, it started switching off by itself. When it first started doing this a couple of days ago, it would shut off randomly twice or thrice a day, but today it switches off about every 5 minutes. Sometimes it doesn't even complete the boot sequence before it turns off.
The effect is just about the same as pulling the battery out. One moment you're using the phone, the next moment the screen is blank. No vibrations, no errors, no lights, nothing. It can be turned on normally and works for a short while before turning off again.
I haven't been able to isolate the problem to any single use case - it turns off with and without the SIM, with/without the SD card, on airplane mode and off, with the screen on or off.
It turns off with every combination of CM11, CM12 and stock that I tried, with stock kernel, default CM kernel, William's kernel and Tangerine kernel.
Although I don't want to admit it, it looks like it's a battery problem. Perhaps the battery lost capacity sitting around in a warehouse for two years? Either that or I was duped by the place I got it from, which seems unlikely as it was spotless in its original packing with all the plastic bits covering the screen, camera and microphone, and a warranty sticker over a screw on the back. Besides, they've given me a one-year service guarantee (it's not the official Sony warranty, though).
Mine is the C5303 model.
Has anyone had this problem? Can anyone suggest what I could do about it? It's a great phone except for this problem
Thanks for any help!
EDIT: Sorry, I forgot to mention that this does not happen when connected to a charger or a computer. Only when running on battery.

you should try to flash a stock ftf ROM with flash-tool ....if the problem still happen with you then i'm afraid it's a hardware problem

Thank you for your response, but I've already tried that, to no avail. This makes me think it's definitely a hardware problem that's related to either the battery or the charging circuit.
However, a recent experiment I tried seems to contradict this. I left the phone on CWM recovery for about 40 minutes and it didn't switch off! I even ran a backup to add strain to the battery, but no, it stayed on.
This indicates that it might not be a battery problem - a battery problem should affect the phone in recovery as well as inside the Android OS.
One major difference between CWM and Android is that Android runs the radios, while a recovery has no need to. Could it be a chance bug in the radio firmware? Is there any way to reflash the radio firmware?

actually i never saw a radio firmware to flash ......but it's not a battery problem for sure ....maybe cpu can't handle the ROM running or like you said radio don't run in cmw then it mite be the cause of the problem
but anyway it's a hardware ...since you are flashing a stock ftf via flashtool then the radio shouldn't have any problems at all !
so you need to go to service center i think to repair it ...sorry for not finding an answer or a direct solution for your problem
good luck man :good:

Thanks for your help. I think I was cheated and they deliberately sold me a faulty phone. I'm thinking of having my phone checked by an independent service center (for a price )
I have another question, if anybody can answer: what does the original guarantee sticker look like? Mine is the one in the attachment, stuck over the central screw.
I'm beginning to think that it's a fake sticker stuck by the shop that sold it to me

I don"t have this Sticker. The Sony Ericson Joint-Venture was ended Yeats before the SP came out... Looks like it is from another phone...
Anyway:
Cwm doesn't use a high current.
Because of stuff I can't explain in English, it could be possible the battery delivers enough Voltage but not enough current for booting up.
Although, it seems more likely to be a RAM error. Yeah, that can happen on phones too.
That would explain the very random behavior.
Cwm doesn't change anything in the RAM when it does nothing. That's why the error doesn't occur then.

AHA! Now this got me thinking. I flashed a fresh ROM without gapps, set the maximum processor clock to 384 MHz, turned down the brightness, switched off WiFi, GPS, Bluetooth, NFC, etc., and now it works perfectly fine without switching off! Looks like you're right, the battery can't produce enough current.
I can now reproduce the problem reliably by setting governor to performance @1.7GHz, turning up the brightness, switching on all the devices mentioned above and recording video. The moment I touch the button to stop recording, the extra strain caused by flushing the buffer to the memory causes the phone to switch off. Bingo! :good:
What does this mean? That the battery is weak? Or the charging circuit is wrongly cutting off the battery?
Thanks a lot for the info! Finally this thing is beginning to make sense. :highfive:

It means the battery is weak. I guess the phone itself should be fine.
When a bettery gets old, it can get a higher resistance. Yeah, batteries have a resistance too. In German it's called Innenwiderstand. Literally translated "inner resistance". It's the same effect like when your car's battery is old. Your stereo still gets its 12V, but trying to start the car will let the curcuit "die" for a few seconds.
The battery in the SP can be replaced, it's not that hard. There are some great videos on YouTube. Please don't buy a battery that is sold as original! Sony doesn't sell spare batteries for the SP. If it says original, it's used or fake.
Buy a battery from a seller who admits it is not from Sony. He is honest to you. Make sure it's a spare battery with good cells in it. Like Varta etc.

Please don't buy a battery that is sold as original! Sony doesn't sell spare batteries for the SP. If it says original, it's used or fake.

Thanks for the heads-up! I've called multiple repair centers and they've all told me they can give me original batteries. I'd better be careful, then!
Do you have any idea where I can order a good battery, or how I can identify which ones are good?
I will be in Eastern Europe next week, where it's easier to get deliveries from eBay, etc. I might even visit Germany! Any suggestions on how to find a battery are welcome.

That's the one I would buy. You see that this not-original battery is more expensive than the "fauxriginals"? There's a reason
You can buy elsewhere too. Make sure the seller has got many good ratings over a long period of time.
A few terrible ratings aren't a problem. There are always some noobs who break their spare parts and blame the seller.
E.g. on Amazon, look for many 4-star and 3 star ratings. They are real. Bought ratings are almost always 5 star ratings.
Don't buy where all ratings are 1 or 5 stars.
The capacity may differ from the original 2300mAh. 2100mAh to 2500mAh is fine. More than 2500mAh should be fake.
You can also buy on eBay where the seller admits it's a used battery in good condition.
I don't think you can buy this battery "" offline". If you do, make absolutely sure the connectors look like in the pictures in Amazon!
In Germany, there are lot Mobile Phone Shops with an Internet Café. Mostly, they are owned by Turks.
Usually, they have a good service. They can replace the battery for you for a few bucks. If you can't be served in one shop, they'll sometimes tell you where a shop is where they can help you.
Hope these information are useful

Thanks for your advice.
What do you think about this thread I bumped into? http://forum.xda-developers.com/galaxy-s2/accessories/polarcell-akku-1800mah-t1269918
Do you think there's a chance that my problem might be due to some other component other than the battery?

It's possible that it is caused by another component. We can't know. Buying a New battery is the cheapest option. I don't see another way to find out.
There are bad third party batteries too. But I trust someone who admits it's third party more. Just rely on the ratings...
Sorry, but I don't have any better advices.

Flash cm 12.1 only with gapps and supersu. Do not touch the kernel settings, dont make the phone overheat too much and try. Try to discharge the battery at 0% 2-3 times and recharge it with the stock charger and cable.
Can you install cpu z and tell us what voltage it reads when your battery si charged to 100% and disconnected from charger ?
It should be 4.2V i have my XSP for a year now and my battery reads 4.130V at 100%.
Solved!
Hi guys, I'm back from Europe.
I know it's been a really long time, but I just wanted to update the thread in case anyone else has the same problem and finds this thread.
Before leaving, I purchased a new "original" battery at a local shop (a pretty large scale distributor).
It looks identical to the battery that was already in the phone, and also identical to the batteries in all the videos I've seen on youtube. The SONY branding is covered by a thin plate of copper, but it's there, so I assume it's not fake.
It cost me 1300 RUB (~20 USD). There was a "Craftmann" branded battery also available, but it was 3x more expensive, so I didn't buy it.
Well, the phone works fine. In the past ~2 months, it hasn't turned off even once, and the battery lasts a day with decent use (~3h GPS guidance, ~1h FM transmitter, always connected to LTE, messaging and email, occasional calls), so I consider the issue solved.
Thanks to all who helped me!

Dead Note 9 "working" again won't boot

Two months ago my Note 9 took a bath in seawater, I got it to a repair shop in the country I was in and the guy tried to fix it but ended up just drying it a bit.
Phone still wasn't working and two months late I was thinking about getting recycled, plugged it and it started as nothing happened but it boot loops.
So I tried flashing a rom with odin, it took hours (super slow) and Failed in the end.
I went to a repair shop and they didn't want to touch anything telling me that it was way too corroded to do anything with it.
So now I have this Note 9 that connects to my computer as it used to and seems to be doing fine aside from the fact that the storage is probably dead.
Samsung wouldn't accept it for a trade-up would they?
You said it seems to be doing fine but said it boot loops and will not flash firmware and its corroded? So does it work? Boot up? You say it seems fine but then say it doesnt work. I dont think you can trade such a severely damaged device

you should have washed your phone with Isopropyl Alcohol after taking it apart. any way, you can try this now. open your phone if you cannot, go to any phone repair shop and ask them to wash it with Isopropyl Alcohol. you may get your working phone again.

Yeah, my bet is that the memory chip connections have corroded, or something that effects the memory chips. would need to be disassembled and Iso cleaned at the least, chips might have to be re-soldered to the board at the worst.
