Unusable Note 4 Overheating, I think

I have a Note 4 that is stock that started randomly restarting. Then it couldn't even boot all the way up. I noticed it was getting very hot near the sim card. After letting it sit for a day, and cool off, I think. I was able to get into stock recovery and do a factory reset before it froze again. However, it still can't even boot all the way to the welcome screen. I assume it is a hardware issue. Any advice on what to repair/replace to fix this? Is it the motherboard? Thanks.

Hi, you could try to flash the stock ROM of the Android version that you're using. If that doesn't help, it's most likely an hardware issue and you have to send it to Samsung or get it repaired otherwise if possible.

Thanks. I am pretty sure it is the motherboard that has gone bad. It won't stay powered on long enough to flash a rom.

Can you access the download mode of your device long enough? If yes, you could use the software Odin to flash the ROM.
If no, I guess nothing than Samsung itself can help you.

when my note 4 died suddenly during the day- having had issues like freezing, laggin and restarting since MM6.0.1- I thought it was ready for the burial but I read online somewhere- too many google pages LOL- to take the battery out, put it to chill in the fridge for 10 mins (I left mine in for 30), take it out and put the battery back in . Totally resuscitated!
Now using Wakelock app and all is- fingers crossed- well i.e.: no more lagging, freezing etc.
(I somehow could not flash custom firmware using my Mac after 3 tries- )

That's EXACTLY the case with mine right now, did you figure out the problem and if you did would you please be so kind and tell us what was it, i'm majorly desperate, i'm thinking a short circuit.

Sorry, no. I was going to replace the motherboard, but didn't find a good deal on one and gave up.

Thanks for the quick reply, guess i should probably follow up too, i'll try to remove the shorting using Elma's solution and if it doesn't work i'll just throw it out, a new motherboard costs as much as a whole new phone, and yeah your Note 4 was shorted as well, most likely due to a poor quality battery or a bad Charger/USB cable or excessively using it while charging.

M2 sim locked and doesn`t recognise OEM battery

First of all, i`d like to say that this is a great community for android users and you`ve been of great help ever since the golden era of my first milestone.
Since my first droid died years ago, i wanted another, so i bought a used milestone 2 with no battery. I ordered an original oem battery from the US and now i realize that the phone won`t recognize the battery. The phone turns on, but doesn`t charge and there is a question mark on the battery gauge.
Any word of advice will be appreciated, many thanks. Hopefully with your help i will eventually be able to bring the M2 back to life.
Edit: i fixed all issues except the battery-related one. I have an original battery, how come the phone doesn`t recognise it? I could use and external charger, but that still doesn`t replace a logical explanation.

Are you sure you didn't get a counterfeit battery? I have replaced the one in my MS2 (BP6X, datecode 2010) with another one, same year, a while ago, no issues. I realise that it becomes harder and harder to get one's hands on genuine, compatible, and working batteries - or recent Android updates.

My Nexus shuts down at 15% but won't turn back on til on charge. HELP?

So, I got a Nexus 6P, I had a Sony Xperia XA1, but, well, it stopped working, so I got a Samsung Galaxy C5, then, that had issues so I traded that in and got a Nexus 6P. It was second hand from CeX. I took it in yesterday to do a warranty test. They found no issues. To be honest, the person who served me looked like she couldn't be bothered. I really like the phone, and I don't know what to do. My friend suggests taking it back to CeX and maybe getting a replacement, but I don't want to do that, I'm really enjoying the device when it actually works. I've used AccuBattery, and the readings jump. One point my battery health was at 53% which was disgustingly bad. Following check, it was up at 89%, which is a lot better. For it to fall again to 58% and back up to 93%. When it shuts down, I can't turn it back on again. At all. It requires a charger. I've tried all the suggested methods of battery 'calibration' etc. None of them work, and I don't want to damage the battery anymore.
Any help would be greatly appreciated.

There's a ton of topics here regarding battery, use the search and you'll see that this is a very common failure. I had the same behavior and a battery replacement fixed it, but YMMV... give it a try, find a good battery and replace it.

It's battery issue, mine was the same. I chatted to google throught the helping section builtin on the settings from my phone and they told me Huawei MUST repace the battery if the phone was still on warrenty. Mine was about to expire, got my phone to the Huawei center in about 2 days they gave me a new battery for free.
My Nexus 6P now last about 2days of medium/low use

Office batteries on eBay, changed mine myself, no more early shutdowns.

Thank you everyone I ended up taking I back to the store and they replaced the phone with an Xperia XZ. I asked if they'd replace the battery, but replacing the phone overall helps as well I suppose haha.

Strange Bootloop :( Phone dead? (x720 BaikalOS with Sergey's thermal)

Hi
I am on this phone since it released so i think that i am not a noob in flashing this Phone but now i have a realy strange Problem. Maybee my Phone is dead
I am on BaikalOS since 3 Weeks and have installed @tsongming recomended thermals from Sergey. It was working flawessly since 1 week.
Today i charged my phone form 30% to 80% and disconnected it from the charger. After this it was really hot Feeling in my Hand. I removed the bumper and was waiting too cool down. After 2 Minutes it started rebooting from itself but stucked in bootloop with a scary sreen. I see the leeco bootscreen and it went to White and black lines over the whole screen. Same Picture is when i try to enter recovery mode. So now its in Fastboot mode since 1h and its colder but i cannot boot into recovery or System (bootloop)
Should i try to Flash a stock Rom in Fastboot? I dont want to Damage the phone by myself so i am asking before i will do more.
I hope the motherbard is not dead
When i plug the phone to PC in Fastboot i see "Android Bootloader Interface" from "LeMobile" in the devicemanager.
Fastboot reboot comand works and AIO Tool Shows "fastboot device Ready"
Hope i can Rescue my phone.
Best regards Daniel

Sorry to hear about your phone: To be clear the thermals wouldn't cause that type of affect. In Fact, the Sergey thermals are exactly the same thermals that are already used inBaikalOS...They are native to that rom. So if you were using that Rom and you flashed the Sergey thermal you actually didn't change anything by adding the Sergey thermal. Because it was already being used.
Also the Sergey thermals actually have heat and battery protection measure built in : See my breakdown of thermals here: https://docs.google.com/spreadsheets/d/1PXD91uBEs0hYvU1tMBq6Ld9Jc7Mm1FZxzwtsLwcmR6o/edit#gid=0
Here is the Github: As you will see the thermals would not cause this type of issue: https://github.com/BaikalOS-Devices...mmit/fc2ef2622ee4dbcbc4c6be512ca11825a37a4626
Now what could cause an issue is if you used a kernel manager and overclocked the cores with the MSM thermal turned off or set too high. But that would have to happen manually. Another potential cause is the usb C cable or charge block caused a short.
Have you updated the Rom recently, did you have Delta enabled, there was an update yesterday, that made my mother's phone hot. So I migrated her to Lineage.
Can you take a picture of what your screen looks like when you have the issue. and post it here.

If your issue is the motherboard, of course I hope that it isn't. I found a replacement board here:
This is much less expensive than what they were charging in November when I needed a new motherboard.

When you get the message take a picture and I will be able to tell if its a hardware issue or not.
There a symptom that can be resolved by using Qfil, and the other symptom is a solder short. Which technically could be fixed by resoldering the chip connection, and you would not need any parts. unless the heat damaged your LCD.

Thank you for your everytime very long and good reply
I know that BaikalOS and the thermals couldnt be the reason of damaging the phone. It was just for explaining what i have done with the phone.
I didnt upate the phone since 2 weeks or later, dont know. I wanted to update it yesterday and before i wanted to charge the phone a little bit. I think the fault was to use the original cable and fastcharge block..... but my wifes phone was charging with this setuo since an half jear so i didnt think it would damage it. Now i Know it better
I unplugged it at 85% and it was really hot. After 2 minutes it rebooted itself and was in a bootloop.
As i told i flashed the 23s yesterday via fastboot and know the strange screen only apperars when i try to boot into recovery. (i tried at first to boot into stock recovery that didnt work. After that i flashed TWRP 3.2.3 via Fastboot and i isnt working too.)
If this is a Hardware issue i am thinking about buying a new phone because i the le pro 3 is over 2 jears old and the battery is going to be bad faster and faster. So i was thinking about to change it for an month. Also the screen is showing an jellow circle in the left upper so i wanted to change it too.
When i would change this 3 things of the phone i dont know if its worth to do that when a new poco f1 only costs about 350€ direktly via amazon.de

Oh I am sorry, that is definitely a hardware issue.​In fact, it is the same exact thing that happened to my older now a paperweight X727. Sorry for the bad news.
Its possible that one of your solder connections melted, and you may be able to repair it by disassembling the phone, taking out the motherboard, remove the heat shield, add flux and solder and bake in the oven for 8 minutes at 400 degree Fahrenheit. Its called a reflow.
https://www.win2uit.com/reflow-soldering/
Here is a link where someone had the same issue and repaired there phone using this method. : https://forums.androidcentral.com/lg-g3/578393-why-my-lg-g3-boot-looping-blue-screen-2.html
I am going to try this method myself at some point, but I need to order a new lcd first.
I broke the LCD when taking apart my old phone.. If successful, I will create a how to tutorial since they are practically nonexistent. I have never tried it before, so it will be trial and error. But, there is no risk that old phone is just sitting in a box collecting dust.
I used to work with a guy that was a master at repairing computer motherboards using the reflow technique, I need to try a locate him, its been years since we last spoke.
Again, sorry for the bad news. I hope your replacement phone is something amazing. Although, many people are waiting until an inexpensive phone with a snapdragon 855 comes out. For me, the Poco phone still seems like a wise choice for $300 or spending a little more and buying a One Plus 6. Of course there is always the option of buying phone with a snapdragon 710 for under $300.
Take Care.

Thank you for the reflow infos.
I will try it when i have some time and if i am able to put the srceen of without breaking it
About a SD855 i was thinking about it too but i need a new phone fast because i need it for my work. I hope the poco will be nice, but i think so because there are many developers working on it.
I also don´t think that there will be an SD855 for about 300 to by and a new Poco F2 or something else isnt in plan. Maybee the first "Cheap" SD855 will come out in the end of this year.
There are 3 other le pro 3 in my family so i will read and write here too

Congratulations!
One thing about Xiaomi, they build quality devices and they are large and successful, so they aren't going anywhere. ( Like out of business anytime soon)
Plus they have an army of developers, with a Xiaomi device you have practically every option available when it comes to numerous versions of stock based Roms (which personally I love) or the multitude of available Roms.
The SD 845 is about 50 to 60% more powerful than our Leeco's and at its extremely fair price, I think its crazy to even consider spending more, unless you must have a glass back or a Amoled screen.
When you get everything setup, please let us know what you think about it. Thanks.

Hi just r recived my phone now. First impression is what you say its pretty fast and not bad quality. Battery etc i will tell you later. But the speed is really insane ?

Hi again. I finally rooted the device now and installed MIUI 10 stable. Now with magisk frankokernel servicely and naptime the battery is incredible good. 0,2% per hour in idle. Very cool. I only charge the phone in my car while driving with Android auto. It's enough power for a day. (I am driving about 1h every day. With maps, Amazon Musik, blitzer.de etc running.)
I have 2 Sims inserted and always lte, GPS high and Bluetooth for mi band 3 aktiv. Very impressive.
Also with MIUI 10 notifications are great. Never missing a WhatsApp etc. I think there is nn to flash a custom rom this time ?
So I would say it's a nice phone for this price. As it has no anti rollback and warranty also with open bootloader. The redmi 6 has anti rollback so it's not so friendly. Also it's not worth to buy a mi8 or mimix3.
Very happy with the new friend.

That is a an awesome review!
I am leaning toward the Poco myself. Although I was also considering the Mi8 Pro, I don't think its worth almost $200 extra for the Amoled screen when the POCO has everything else...spec-wise.
Thanks

Nexus 4 dead after changing the battery

Hello Forum,
I replaced the battery in an old Nexus 4 today. After connecting the charging cable, the charging animation appears as usual.
But now the device can't be switched on anymore.
Opening the case went smoothly, I wouldn't know that I broke something there; also the exchange of the battery went without problems. Pressure point of the switch can be clearly heard, etc.
Does anybody know this and maybe has a hint (except for the opinion that the N4 is probably ruined)?
It would be a real pity about the smartphone. I've got Android 10 on it, which worked very well.
Greetings, Django
Translated with www.DeepL.com/Translator (free version)

It may be the new battery that is defective. Try to reinstall the original battery and see if the phone boots normally.
I still haven't found a good quality replacement battery. Some lasted 6 months, others a few weeks and one came defective and the phone didn't even boot, like yours.
