Attempted screen replacement, issues, please help! - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hey everyone,
Followed the ifixit guide to replace the screen on my i337. I didn't seem to run into any troubles during the process, but when I went to charge the phone again (it's been dead for a few weeks), nothing seemed to be happening. So I pulled it apart, checked all the connections, and without replacing the midframe popped in the battery to check my work, to my surprise the screen came on and it started to charge.
So, back goes on the midframe, and it's not working again. After a bunch of trial/error I seemed to figure out that when I put in and tighten the screw next to the SD card slot, it seemed to be shorting something out and the screen would turn off immediately.
I was still in the process of trying to figure out what was shorting out and how to stop it when all of the sudden everything stopped working, no more charging, screen no longer turned on, etc. At this point it's not pulling any current from the charger when I plug it in (0W on my kill-a-watt, it was as high as 9W previously when I plugged it in above).
I tried putting everything back on the old screen, but nothing is different, still not charging or pulling current. Tried different USB cables (known to work on other phones), different chargers, no difference.
Not sure where to go from here, if I've someone killed the motherboard, killed the charging port, killed the battery, etc and don't want to go around throwing money at a phone that might be totally broken. If anyone could give some insight on how to test if the usb port or the battery are what's ****ed up, or if you have any other ideas, that would be great.
Thanks in advance!

[Q] LG G2 not charging at all!

Hi all,
I just bought an LG G2 (D802 international unlocked version) and the behavior when plugging in the charger cable is very strange:
When I plug in any charger (tried 4 different ones with different cables incl. stock), the phone is not charging.
BUT, there are a few strange things happening:
1. On the lock screen it shows "Charging"
2. In the settings menu under the battery menu it shows "not charging" (this is different from being unplugged, then it shows something like "discharging")
3. Sometimes the popup comes up when I plug it in, but not always.
3. When I turn the phone off and plug the cable in, the display lights up (also the LED) and it shows the "charging" battery symbol.
IN ANY CASE, THE PHONE BATTERY IS NOT CHARGING!
Here is what I tried so far:
- Used 4 different chargers & cables
- Tried to charge via USB
- Did a factory reset
Nothing helped so far.
I suppose that its a hardware failure, but maybe someone has a different suggestion/solution?
Only thing i can recommend is maybe do a factory reset to see if that corrects it which i doubt it will. Other then that i would have the phone warrantied then.
If its a software issue then that is at the kernel level. I would assume its a hardware issue though

I sent it back to get a replacement. Was just wondering: Is it possible to remove the back cover on that phone without damage/loss of warranty?

I got a replacement unit, it was a hardware issue.
The same problem i am facing with my G2 Sprint LS980 and i am pretty sure this is not hardware problem because my phone had signal issues and LG charged repair fee around US$ 55. My phone was not rooted before repair and also my phone was charging fast too. It has installed ZVD7 ROM. But once i get my phone it was completely changed. They rooted my phone, They converted my ROM from ZVD7 to Cloud G3 2.2 and they also installed TWRP recovery. But still phone is not charging same like as you posted. I just noticed another thing phone is perfectly charging in TWRP recovery mode. Therefore i am 99% sure it's not hardware issue. 2nd issue is that phone is also not detect with my PC. I tried different drivers but failed. Anybody can help me or suggest me any suitable ROM and provide me correct driver or PC suite?
having same issue , have u solved??

Not yet Dear...It is the piece of junk for me. Now my ROM has been deleted. I want it back
I have the same problem. The phone is acting very inconsistent with charging after I replaced my broken display. This is the second time I replace the display, and it didn't cause any issues the first time. Basically, my phone won't charge more than maybe 2% over a period of 12-16 hours. The phone does not discharge as others have mentioned in previous posts.
No one seems to have a solution to this problem. Some people online are arguing that is it a "security measure" LG have installed into the phone, which makes it impossible to properly charge the phone without an official LG charger/cable. However, I never used the official charger, but been using various chargers and cables without problems!
But now comes the really weird part. I decided to take off the backcover, and then plug in the charger to see if pushing down on different parts would somehow fix it (loose connections etc..). But before I got around to test such hackery, I plugged in the USB and the phone suddenly started charging! I proceeded reproduce the problem/solution, and the result was very confusing: no real charging with backcover on; perfect charging with the backcover off.
Would anyone here on XDA have any ideas as to why this is happening? I've been thinking that the connectors on the backside on the cover might have something to do with it. Not having the backcover on does not seem to affect the phone at all (i can use it like I would without the cover).
TLR: My phone won't charge with the backcover on, magically works when the backcover is off. I suspect that it might have something to do with the connectors on the back of the cover.
Maybe putting the back cover on the phone is causing a grounding problem or shorting a circuit. Maybe put some insulating material on the inside of the back cover and then put on the phone?

Yes, I thought about doing this, trying one connectors at a time. Do you think that the sticky part of a post-it note like do? I don't have electrical tape lying around atm :/
Anything that is non-conductive should be fine since it is just a test.
You could also use a non-sticky piece of paper between the cover and the phone's components.

So you solved the problem?
I have very same problem decon89 described - I replaced screen and cannot charge it properly. And even worse: charging is possible with the phone being switched off completely. And after phone is charged - I cannot turn on the phone unless i open back cover and unplug-plug battery cable. Phone MAY turn on without unplugging-plugging battery, but it is blind luck. Yesterday i accidently turned off my 100% charged lg g2 and could not turn it back on during whole day. If someone has a solution please share it.
Hi everyone,
I'm so sorry for not following up on this thread. I haven't fix the problem yet, but it worked for same time, then started acting up again.
I've put a few strips of electrical tape on the bottom part of the phone, behind the black plastic thing. I did this because of an issue with my display having a loose connection. This fixed the screen problem, but the charging fault came back.
The idea of putting a piece of paper between the battery and cover did not work at the time, but I'll try it again tonight.
As I'm writing this, the phone is charging with the cover half off. It works, charges, no problem. I can even use the phone even though the bottom part of the cover is off.

[q] totally bricked lg g2

IT ALL STARTED when my wife dropped phone and cracked the screen slightly and touch in some areas stopped worked.
Me being a technical person, went ahead and bought an lg g2 lcd+digitizer replacement off ebay and made sure it was OEM and had the LG logo on it. The phone is an ATT phone by the way and made sure it was for D800.
The part arrived and I went on my merrily way to replace it VERY CAREFULLY. The screen fit in perfectly and I reassembled everything carefully, connector by connector screw by screw.
When the time came to turn it on, it actually turned on and booted normally and the screen worked, the touch worked (altough some letters on the keyboard were douple/triple tapping,etc.) I ignored that and ran into a problem where when being on a call, the screen turns black as normal, but won't turn back on at all until a hard reboot is done. I went out and researched that this was the proximity sensor malfunctioning and that the replacement screens do not come with some sort of grommet that holds it close to the screen and blocks peripheral light. Well, I was annoyed, and went ahead and opened it again to see If I can remedy the proximity problem.
After some adjustments by the proximity and reassembling the phone, it booted up. I saw the LG logo, followed by the ATT startup chime and then, poof. All dark!! So what follows is a succession of fail after fail to try to get it back up and running:
-reopened phone, reseated connectors, nothing, same problem
-reopened phone, found that i hadn't routed the antenna wire correctly and that it had some metal part in between the wire that may need to be making contact with the metal on the frame. Still nothing, same problem.
-a bunch of hard resets, same problem.
-Try to go into restore mode, clicked yes on restore. Even worse after restore all I get to is the lg logo.
-As a last resort, went into download mode by plugging in USB to computer and phone, holding UP vol button. It went into 'download mode' and I went ahead and followed instructions on restoring the factory firmware flash. The process was 15 percent complete when it died, shut off.
-tried the flash process one more time and it went to 22 percent and died.
-knowing it's a hardware thing, I reopened phone and triple checked everything again. After reassembly, phone is TOTAL BRICK. No power, no LG logo, with usb charger and power outlet charger. No restore mode, no download mode, NOTHING NOTHING. Last known battery level was 13 percent when I was doing firmware flash attempt.
WHAT IN THE WORLD IS WRONG. Any experts know what I can check at all?
I managed to revive the power some how by disconnecting battery ribbon cable and holding power button to drain residual charge followed by reconnecting battery cable and plugging in charger.
I started the firmware flash and it failed at 8 percent because phone shut off. I swear to god..
nevermind. After the last post it wouldn't start again, disassembled, and basically found that the lcd ribbon cable connector pins were jammed beyond use. I'm pretty sure this wasn't the problem though in the first few times I opened it because screen worked fine. I disassembled more and found that the super glue I used totally burned into a small portion of the frame where the back of the lcd sits on as if it were some kind of acid or something. These may have been the culprits but I still think there was something else going on. If it hadn't been for that piece of **** proximity sensor this wouldn't have happen. The phone is a total loss and threw it in the trash. Done, RIP.

Thought you were going to say wife haha. Sorry to hear about your phone, just don't go giving your phone to your wife anymore . Thanks for sharing your sad story .

Note 3 not turning on. Sudden death? Hardware problem?

Let me start from the begining.
So the other day I plugged my phone into USB in order to charge it (I had to keep it close to me hence why I didn't plug it into the wall charger). The phone was charging, showing up as a media device on the lappy, etc. I was doing stuff on the computer then I heard it vibrate so I went to see what it was. The blue notification light was on (facebook notification most likely) and when I pressed the Menu button the screen didn't come on. I also tried the Power button but same thing. So I decided to restart the phone. Since then, it hasn't turned back on.
I tested the battery in another device and it's working perfectly fine. Neither recovery nor download mode work. I tried to do some of the tests people recommended for sudden death, like plugging it into usb and leaving it for a while, trying to kick start it (putting battery in while holding the recovery buttons) - you name it, i've done it. I even went to the lengths of taking off the back cover to see if theres any crap that got in there, maybe a loose connector, anything burnt - nothing. Unfortunately, I don't have a multimeter to see if there is a charge running through the board. Looks like sudden death to me, the only thing is - I rooted the phone on the 1st day I got it and I don't live in the country where I bought the phone so sending it over for warranty repairs would be a pain in the ass. What can I do? I would greatly appreciate your help, if you manage to help me fix my baby, I will ENSURE to send you a donation for a nice, big, cold beer (or maybe a few).
Looking forward to any answers! I really need my phone, I use it for work.
It seems like a hardware issue... you need to take it to a local store to scan it's hardware.... maybe something gone wrong while charging which made something be destroyed inside it..... hope its not the motherboard.....
it happens sometimes, when charging current fluctuate, it destroys the charging circuit and in result it damage the whole current circuit, local repair shop can solve the issue.

Help! Battery drained, phone won't turn on, battery charging icon flashes on and off?

My phone had been working perfectly fine, as well as charging perfectly fine. Recently, I accidentally let it drop to 0%, which I don't usually do. I went to plug it into the same wall outlet as always, but instead of the usual charge process, the battery icon with the lightning bolt in the middle simply flashes on the screen and then turns off, which happens over and over again.
It should be noted as well that about 3 weeks ago my phone get fairly wet. After that incident, I turned it off till it dried, powered it up, and everything appeared to be totally ok. No problems since then until this.
Other facts:
-I can safely get into the recovery menu (power + vol down), which is stable, but any menu selections result in the Motorola splash screen for a quick second and then the phone powering down.
-The computer will recognize the connection to the phone.
Attempts to resolve:
-New cable, new usb hub, new wall outlet
-Trickle charge from the computer (same flashing)
-Phone in rice to remove moisture
-Toothbrush cleaning of Micro-usb port (suggestion from another thread)
I'm pulling my hair out, and I am considering prying off the back and replacing the battery. I have searched other threads, but have seen various solutions none of which worked for me. If anybody has any idea how I can fix this please help!!!
Thanks in advance.
Unfortunately most probably is the hardware problem. I had similar issue with razr. Splashed it on the beach, quickly washed with tap water, dryed it and for couple of days like nothing happened. Then suddenly digizer stopped working. It was motherboard. Luckily one xda member donated me the same phone with broken screen so I replaced motherboard by myself.

Thanks for the suggestion. Well, I got it back working again, by charging it for 5 hours straight and then not charging it for an hour. Now it appears to be functioning alright, with the exception that it once went from 40% bat to 15% to 0% in a matter of seconds and I had to repeat the procedure to get it back on. I have another turbo with a broken digi that I could cannibalize but I have no idea what to replace... the battery? Bizarre issue, but I guess that comes with the territory of water damage.
Maybe some part is still wet. If another Turbo has only broken screen, then is probably the easiest solution to take screen from the (ex)wet and put to another one. You just have to have proper screwdriver.
Replaced battery now Droid turbo flashing when I charge?

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.

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.
