[Q] ATT Galaxy S4 SGH-I337 Boots up (sometimes) when battery is inserted

Update 1
I've discovered that if I plug in the phone, I am shown a gray battery with a progress wheel. In the past, the phone has gone less and less far into the boot process before shutting down. Thinking about it again, perhaps it's a power issue. I've ordered a new battery and usb board on Amazon, total 15 USD. I've already disassembled the phone and I'm waiting for it to arrive. FWIW I do see some physical damage to the inside "tongue" insomuch as two of the pins are just floating with no plastic. That is to say the plastic is broken off and missing.
Original Issue
Hello everyone:
I bought a Samsung Galaxy S4 (AT&T Branded) SGH-I337. I thought it was working. When I insert the battery, it boots up about 1/10th of time, but only about halfway. Occasionally it does the same thing when inserting a USB cable (I don't recall if it was to a PC or a power supply). If I can get it to boot, I CAN get into recovery or download, but it shuts off the same way. Someone took a look at it from a repair shop and said it may be a software issue.
I have tried disassembling the phone and using canned air on the power key, though it didn't seem to be the issue in the first place.
I saw a video from thailand on youtube where a person put in a microsd card, connected a power supply to the battery terminals on the phone, then connected a usb cable. The phone booted. I think the idea was that the original firmware would now have to be installed. Any idea what this is or how to do it?
Thanks for any help!

*** Sorry missed your update!!!***
Would you have another battery to try 1st before dismantling it? They are very cheap to buy

No, but I bought a battery and usb board for a total of $15, so if either works great. Does the battery cause this issue at times?

Just replaced the usb board and battery. Still only boots to a point. No idea what to try next. Any input appreciated.

I had the same issue with my previous Samsung Galaxy Express, it turns out that this issue was caused by the power button being worn out and stuck as if it was pressed down. If you look on YouTube you can find some temporary fixes to allow you fully boot your phone. Although ultimately if this is the issue then you will have to get the power button replaced.

Unable to boot up, Red light when charging issue

I have been unable to boot up my letv 1s device, I have tried everything listed on this forum and other forum to boot up my letv device. Including removing the battery and reconnect them back again.
Recently, I tried to repair it to local phone repair shop, they told me it needs a battery replacement. I bought the battery from aliexpress and replaced them, but it still doesnt boot up.
The repair shop gave up and gave me back the phone and told me the EMMC is weak (I'm not sure about this).
I disassembly the phones and try to figure out the problem, I am guessing the problem might be with the charging board, I am posting the video here hoping someone pro could help me solve the problem. I'm guessing its the charging board because everytime I connect the device to the PC, it kept reconnecting when I tried to FLash a new ROM.
Here are the video of the board kept reconnecting when I tried to connect them to PC

I really hope someone with more experience could give me more insight about this, thanks.
PS: Please dont ask me to charge the phone again with original adapter and cable, because thats the first thing I tried and I charge it for more than 24 hours already (I even tried to buy a new adapter and usb type-c cable). Oh and I tried connecting to PC with the battery connected also, and it kept reconnecting.

Hi, I also have same problem, but still no solution.

Hi @casper2201 , @softkans and any one with the same issue,
I too had the same issue. It started with the charging rate becoming too slow (1% increment in 25 minutes of charging). I switched off the phone and left to charge for around 35 hours straight and came to find it 79% charged. Then I tried flashing the LOS14 after LOS13 ROMs but in vain. I also fiddled with the Kernel Adiutor, still no help. The charge won't increase when the phone is on so I left it to discharge until it switched off. Then the main issue showed up with red light always on when charging and blank screen.
I also posted about it here, but no one replied. Then I took a leap of faith and went to a local repair shop. He confirmed that it was a hardware problem and the charging module needs to be replaced. Just now I am coming from the shop itself after picking up my phone. Its working fine till now *fingers crossed*. He charged me ₹1300 ($20) which is a little high for the service but it doesn't matter as he was the only one ready to open it as there was the risk of cracking the screen.
So, summing it up, if you have the same problem as that of mine then you need to replace your charging module and I think it will be fine.
Charging module replaced.
Current condition of phone.
The rubber bands will help the adhesive strengthen.
Thanks,
Abhishek

Yesterday when I was done with setting up my phone, I put it to charge and the same issue has come again. Its not charging and the "Red light of Death" is back. Today I'm going to the repair shop again and see what he can do now.
I think this is the end and there is no point throwing away more money on the device anymore.

Sir same thing happened with me....phone is not charging red light alert and display blank...please suggest me what can I do
I want my data back from that and its not starting my data is really very important I can't loose that
Help me and tell me what can i do so that my data will not loose and my phone starts

Remove display and disconnect battery. If it won't be alive again that's probably power management unit problem and you won't fix that way.

Galaxy s5 won’t boot up

Please can someone help me with a problem I’m having with my Samsung Galaxy s5.
I put my phone on charge before I went to bed and when I woke up it was still showing a red LED. I knew this was wrong because it should have had enough time to charge and turn green. I had not powered the phone off before putting it on charge and I plugged it into the same USB 3.0 charging lead I have been using for the past six months. I unplugged the phone and pressed the power button to light up the lock screen but it didn’t light up.
I’m thinking possibly something has either shorted or over heated and fried something either on the charging port assembly or one of the chips adjacent to the port while the charger was plugged in. It seems like only a trickle of power is getting through to the phone. When I plug a different USB 2 charging cable into the phone, without trying to power on, the charging icon appears but shows no charge at all in the battery.
I have also tried the spare battery I have but it’s still the same. I know the spare battery is 100% fully charged because I store it in a separate charging/storage box which shows a green LED when it is full. In fact the one which was in the phone at the time is also fully charged according to the charging box. Neither battery has got warm at all inside the phone. I’m confident both batteries are fully charged and totally fine and the problem isn’t with the batteries.
At this point I removed my sim card and also the MicroSD card. I needed the sim to use in my spare phone and I wanted to see if the sd card could be causing the issue but after again trying a normal reboot it made no difference.
I’ve tried several possible things I found on google but nothing has worked. Between each different thing I tried I had to remove the battery for 10 seconds and insert it again to get it out of the boot loop so I could try something else.
Initially when I tried booting into safe mode, then recovery mode and then download mode it brought up the screens for those but in each case after a few seconds the phone powered off and went into a boot loop so I couldn’t attempt any recovery options such as clearing cache etc. Now I cannot even get it to start any of those modes at all and all that happens is the phone does a little vibration, displays the Samsung logo and then just boot loops no matter what I try.
I have tried removing the battery and leaving the phone for a few hours then powering on again but it still just loops.
I have tried pressing and holding Vol-down when plugging it into my PC using a different USB 2 cable and windows acknowledged a phone was plugged in but said it couldn’t connect or recognise the phone and suggested the phone could have a fault.
I don't know if maybe my USB 3.0 lead has a fault that could have caused it or if there could have been some electricity spike while the phone was plugged in, or as I said a component has just fried.
I strongly suspect this is a hardware fault and not a software fault but as I’m not a phone engineer I have no idea about how to trace any possible hardware issues or what might have gone wrong. I would really appreciate any help or suggestions about what the problem might be as this has been a great phone for the last 2 years since I got it and I’d be sad to have to junk it and buy a new one.
Thank you.

I would not junk it yet......
You had mentioned that you go through a lot, just to get phone into Recovery ( " Initially when I tried booting into safe mode, then recovery mode and then download mode it brought up the screens for those but in each case after a few seconds the phone powered off and went into a boot loop so I couldn’t attempt any recovery options such as clearing cache etc. Now I cannot even get it to start any of those modes at all and all that happens is the phone does a little vibration, displays the Samsung logo and then just boot loops no matter what I try." )
OK, just my 2 cents here on this... Why not trying to goto Recovery by pressing and holding the Volume Down (vol-); Home button, and The Power button all at the same time. (yes, if you have a Recovery, and its works, you should be able to boot right into Recovery- >Now, (I would, cause I've been there..) I would also have a PC going with Odin open (Plus the Latest Stock Rom) ... If it works, you would flash the Stock ROM, to clean up anything, giving you all stock, but you can change that of course ...then go from there...
Second, if you can not still get to Recovery.... Have you tried a Stock USB Cable, only asking.... Obliviously something is a miss... with Power... IF phone is off, and you plug it to a power source ... then system has power, and these can power up with just the usb cable, without having the battery in..... Been there. Can add the simple fact, if using just a Micro SD cable, they can bend the Power Board. Believe me (Had to fix the Wife's S5 a few Frinkin' times....) That is why, I say using the Stock Cable, or even a USB 3.0 Cable (like the stock one) does help with power issues when the Micro has bent up the power board...
Will check back and see if this may have you to Recovery or fixed... sure hope this can help you out

Thanks for replying godofsalt.
At the time the phone was plugged in to my USB 3 lead which charges faster and all I can think is that perhaps there could be a fault with the lead or the higher ampage of using this lead caused a circuit to burn out.
I have around a dozen USB 2 leads and I've tried your idea with 3 different ones but none of them will fire up the phone at all with the battery taken out.
I am sure this is going to need some kind of replacement either of the charging port or the motherboard. I don't rate my chances of trying to do it myself and I don't think it will be economic to take it to a shop so I've found a better option by buying the same phone which is second hand but in good condition. That way I know I have all the additional accessories already for probably the same price any shop would charge to fix it.
In future I'll stick to using a decent USB 2 lead on the 1 amp charger I used to use before and hopefully this will not occur again.

G500F battery graphic/boot loop
Had the same problem a few days after installing a 9.0 Rom. My battery is brand new and all cables aren't too aged, so I thought this had to be a physical fault of some kind, but then I had the thought to flash an older bootloader and just like that my battery started taking a charge again and I could boot up. Switched to Flyme os for a while the went back to 9.0 again, with the lastest bootloader and the thing stopped working again. Don't know too much, but I'd try and flash a different bootloader to see if there's any difference. My device failed right at the Galaxy logo, then looped the charging graphic endlessly but would strangely go into download mode and not fail. Don't know if this helps, just thought I'd share my solution.

Thanks for replying henderia93.
My symptoms are very slightly different in that the phone couldn't maintain any of the modes I tried for more than a few seconds before going back to the boot loop again so there was no chance of trying any software fixes including flashing the ROM. Now it won't enter any of those modes at all. I'm certain that's due to only a trickle of power getting through to the main board, not enough to maintain any recovery modes, so there is just enough power for it to attempt to boot, but no more so it just keeps looping, most likely caused by something that has blown while on charge.

I ha e taken so many of these a part... Like I may have mentioned, there is a Board, just for the USB (data and power (i still have 2 of them)).... In short, you really have to pretty much take the phone a part. Being very careful with the Screen, and the "Sticky" LEDs and the Home button. There is a lot to it actually.
Like I said, been there done that... Cheap to get, takes some time but it is possible to replace that board. It's a separate board different from the actual main CPU board.
I would have to find it, but I had a manual, for taking these a part.

While I've been looking for answers about this I've seen teardown videos for the s5 so I can see what the port assembly looks like with it's little PCB behind it. As I have a replacement s5 on it's way all I need to decide now is whether to keep the old handset for spare parts or see if I can follow the teardown video to try and install a new port assembly to get the phone working again as a spare.

Yep, me too, seen many vids on the tear down. I decided to go a bit more, IMHO, to have an actual manual, PDF, when I did my first one, many years ago. So, can read, and use photos wisely. Seen too many Utube crap, where the break it, destroy it..... crazy!
Well, at this age, not too sure what to do my self. In our case, our present service is cheaper to Keep these. Grandfathered in, and we pay a but less, than going to any other carrier. Plus, these newer phones are not cheap at all.
True, it up to you. hope all goes well.

Sorry I am a novice so please excuse my question.
Are you assuming that the usb port is shorting even when no usb cable is inserted? As you put a fully charged battery in with no change it would seem that the act of charging is not involved.
Have you tried a voltmeter to check the voltage at the battery charging pins?
Have you tried to check the voltage at the two pins commonly used for a wireless charging adapter (to the upper left of the battery) to see what the voltage is?
Sorry if I am off base.

Moto G4+ not turning on.

My phone doesn't turn on nor can it turn on in recovery mode neither and seems to be dead... The only signal of life is the blinking white led next to the fingerprint scanner.
Here's how this happened: The phone was charging very slowly, I thought this was a problem with the cable so I tried other ones without success, I continued using the original, days later it stopped charging so I opened the phone very carefully and saw the battery conector raised ever so slightly, I pushed it back in place and noticed that the flash flex cable had some kind of bump that was caused by some kind of chip under it, maybe I sat on my phone some day and caused this but I don't really know. So I reassembled the phone and now it won't turn on.
I've tried to "unbrick" the phone since apparently that's what causes the blinking white led and not being able to turn on the phone, but unfortunately, the phone won't get recognized when connected to a computer, this means I can't do the unbricking.
I want to know what else could this mean? Is the motherboard dead? Would the led blink even when the motherboard is dead? What can I do?
I've tried(in order to get my phone to show up on the computer):
*Using different kind of usb cables(including the original).
*Connecting to other computers.
*Installing Qualcomm and Motorola drivers.
*Running PC on test mode and disabling signature checks.
Please tell me your opinions, do I buy a new phone or is this fixable?

Originally, I would have thought your issue might have been to do with the charging port (possibly explaining that your device can't be identified).
Just to confirm, all the connectors that you saw, including those attached to the motherboard, are all connected and it's a good connection?
It's entirely possible the motherboard/flash memory is dead - so not being to load the bootloader, though I would have thought you'd be able to see Qualcomm HS-USB 9008 in Windows if your device can't boot to the bootloader (it'll drop to the Emergency Download Mode).
I honestly do not know what the issue/issues might be, though you could take it to a service centre/repair shop and see what they say (get them to inspect the device). Given what you've described, it's possible you may be better served by a new device rather than spending money fixing up this one.

Thanks for the reply, I checked all connectors and none seem to have problems so I'm going to take it to a repair shop as you say, depending on what their diagnose is, I'll consider buying a new phone. Once again, thank you.

Try to hold the power button and the volume down buttons together for more than 2 minutes. My moto g4 goes dead sometimes and nothing I do will turn it on except holding those buttons for like 2 to 3 minutes then it reboots to fastboot and turns on. It might not work but it works for mine and its worth a shot. It takes a few minutes and I dont know why but it does no more 3. Let me know if it worked.

Galaxy S10+ shuts down randomly, does not turn back on.

Hello
So, I've got Samsung Galaxy S10+ AT&T model with a very very weird issue.
The phone has so far died 4 times already. After each time I take it to local Samsung Service center (I'm in Europe) and the technicians turn the phone back on after plugging it to a device which directly sends the power to motherboard, excluding the battery. But the thing is that solution is temporary, the phone developed this issue on January 10th this year and since then I'm kind regular visitor to the local Service center.
They can't determine what's causing the issue. If anyone here has experienced the same issue and found a solution for it I would be more than grateful if you could share it with me.
European authorized service center can't do anything with US models, basically Samsung's warranty works only regionally and not worldwide, well, shame on them for that. Will think twice before buying next Samsung phone.
Couple facts:
1. The phone does not force restart when dead.
2. The phone takes minimal charge when the issue shows up, the technicians at local service center said it takes about 200mAh when dead while it should be doing around 2000mAh normally.
3. Windows 10 PC does recognize (plays sound) that some kind of device is connected when hooking up the dead phone to it, but the phone does not show up in device manager. Also Odin or any other software can't detect it.
4. The only temporary solution so far is to hook the phone up to a Samsung device which sends the power directly to the motherboard, so the power does not go through the battery, but the battery health is excellent.
If additional details are needed I would be happy to provide them, let me know!

I have my old Note 3 (T-Mobile branded) that does that i could never figure out what causes it even after going back to stock original (unroot). Only difference is mine does take a charge and charges fine in your case either
1. You charging port is damaged in some way causing not to charge properly
2. (Unlikely) but battery is defective somehow and won't hold a charge
3. Your cpu is overheating causing a shut down

Thanks for the reply.
Well I think mine is quite a different of a scenario
1. The phone charges fine until it's working, it functions like a normal phone before that random shutdown occurs.
2. I too had that doubt, but it lasts very well so not sure about that.
3. The phone gives no signs of overheating ever. Not even while charging. The random "death" scenario occurs randomly when not on a charger. The phone is sitting in perfectly functioning state and the next moment you take it to unlock and suprize, surprize... it's dead. So far only temporary remedy is to take it to the service center and plug it to the special Samsung gadget to directly send the power to motherboard.

If your phone is still under warranty i would ask them to replace the motherboard, it sounds like it's defective in some way.
