S6 hardware troubleshooting - 3 phones can't figure out the issue - Galaxy S6 Q&A, Help & Troubleshooting

Hey y'all, so I'm not sure how well hardware related questions go down on here usually, but not sure where else to ask. So I have about 2.5 Samsung Galaxy s6's. All were given to me at different stages slash periods of time and none of them exactly work fully. Where I am at now is sort of realizing that either: 1. I have to faulty digitizers, or 2. the one battery I have between them is completely shots, or 3. a combination of one and two as well as some other s*** going on.
So what I have for parts AR, two motherboards two digitizers, three bodies, and one battery. I get kind of the same issue switching between the motherboards which is this: I will plug the phones in to my computer and it will read them and say something like SM and then the numbers that represent the s6, and I'll have a either red l LED for a while which will then turn green after a while charging, or a blue LED from the get-go which I believe just stays blue the entire time. Now, the weird thing is that neither of the phones will turn on, however, whenever I push the home button with either digitizer or either motherboard, it will cause the LED to turn off, but will not cause the phone to stop being recognized by the computer. When I say recognized by the computer I don't mean it shows up in the my PC folder, like where I can access the files and such, it just shows up in the device manager, thus giving me the impression that it never actually turns on. This also happens if I end a press up on the volume at any point in time. Also worth noting whenever I unplug it from the computer or just from the charger, the phone will power off completely as in not be recognized by the computer. So, any ideas? I'm thinking of just selling the phones as is maybe for a 150 total for everything but I'd like to fix that myself if it's just something as small as a battery issue. the volume up button and the home button turn the phones off though, is what really perplexes me. Thanks for any insight, much appreciated for the read and have a good Thanksgiving.

dang man, id just sell em unless you want a winter project. I just bought a Sunfire sub that has some issues for a winter project, but thats because im a dork and i like that kind of stuff. Anyways, my opinion is just to sell it and get something else that works. I had a buddy offer me a HUGE pile of phones and their respective parts to fix them for like $200 and i gave a hard no.

Damn never heard of such an issue? I'd had hoped that the volume up key as well as the home button both restarting (or, turning the LED off for about ten seconds at least) would have been some kind of dead giveaway, if not just a straight up common occurrence, haha. I even got ANOTHER S6 last night from a homie (asked her if I could borrow the battery lol, she just gives me the whole broken phone) to try and switch out parts, which I'm gonna give a quick shot at tonight at least. But man, no responses other than hours has me quite discouraged :') lol thanks for the time to read at least tho my dude ?

Universal plunges from a 3 story building... will it survive? place your bets now.

I had to jump over some stupid fence today at my work (didn't want to go all the way around), so i asked my friend to hold my universal while i jumped.
maybe i should have held it myself, because the universal slipped from her hands, and fell down the 3 story building, hitting many many stairs on the way down.
from a first glance i thought its the end of my beautiful relationship with my uni.
but actually after opening it up and checking its insides - it looks pretty okay! nothing seems to be broken or loose...
the problem is: is won't even start. so im trying to discover where malfunction is.
i've tried:
Switching batteries
Plugging it in to a power source (computer / wall)
Dismantling body and screen, tightening all of the connectors
Bootloader mode - not showing anything
Connecting with MTTY - but i can't even get it to connect
Turned on, waited for 5 mins and called it to see if it'll ring (to eliminate screen problems) - forwards to voicemail
Nothing worked, the screen is always blank.
when i plug in a power source, a red light flashes REALLY quickly, and then goes off, after that nothing happens.
the only thing that gave me a clue its still alive somewhere inside - when i plugged it to my computer, windows alerted me i plugged in an unknown device, even when i tried to put it in BL and connect again.
Does anyone have a clue what i can do next to find where the problem lies, and bring my love back to life???
please, i need help on this.
Mine fell a few feet from my hand to the (concrete) floor and was the same - no signs of trauma but completely dead, aside from a light when connected to the charger.
I think the damage will be to the mainboard, so it's a either a case of getting a new board and fitting it, or buying another universal and selling the dead one for parts. I opted for the latter.
My Condolences!! as long you can not find some lose cable or what so ever I believe you will not able to bring your "love" back to alive.
After connecting to your Computer RED light and Your computer doesn't recognize the Device indicates major issue.
Unless you have someone that can work with JTAG. http://forum.xda-developers.com/showthread.php?t=309291
hehe, thanx for your replies.
i don't know anyone who deals with jtag, but maybe it'll be a good idea to look for a private repair lab which works with jtag.
i guess for a small amount of money they could help me find the problematic part.
i wanted to avoid sending it over to a some random repair lab, because they might turn out as just some amatures and tell me that the whole main board needs to be replaced, instead of a specific part...
so i'll start with some searching
anyone else have any more suggestions?
mine fell from my pocket and red led pops up only when connected to the charger.. i sent it to ppctechs.. they put it under the infrared oven and nothing happened, so its not lose solder nor connectors nor nothing.. its the mainboard, its hard for it to be replaced as far as component level goes.. but who knows.. personally i think just sell it for parts.. sorry, thats what i did and boutght a new one off ebay for 400
good luck and sorry to hear that..
Am I allowed to cry on this forum ????
One request to Modes... Shall we have a crying smily(?)

Dropped my phone, won't boot?

Been a watcher on the forums for awhile, now I actually had to sign up and get some help, LOL.
Anyway, dropped my s2 skyrocket, noticed that it kept trying to reboot every now and then when I used it the same day. The next day, I plugged it in in the evening, and shut off, rebooted, but the screen would go black and the phone would vibrate with 2 seconds in between vibrations. It gets to the "Samsung" word, then the screen goes black in the style of an old tube TV (with the thin white line at the end). Then the vibrations start. So far a useless phone. Took it apart and checked connections carefully (I'm used to working with processor boards quite a bit).
What do you guys suggest? Damaged memory? Should I attempt to reflash? Stuck power button (seemed ok, though)? Bad screen?
Well, probably some kind of physical damage, but hard to say. Anyway, you posted in the forum for SGH-I777 but you have the SGH-I727, so I would suggest that you look in the correct forum.

Oh, thanks for the heads up. Yeah I just figured out that the i727 isn't in "Top Devices" or "Legacy," so you have to go to all forums. Ugg. Already moved. Thanks to whoever notified mod.
Anyway, yeah, any help would be AWESOME. What physical damage would prevent booting past the "Samsung" screen and default to a black screen that intermittently vibrates?
I'll be honest, if ur asking that question probably something u don't have the current skill set to fix. Try to Odin back stock, but if it started post-drop you may be SOL and in need of a new phone.
Got it into download mode after multiple failed attempts. Each time I would get it into download mode, the screen would shut off after about 5 seconds of being on. I tried several combinations of plugging it in first, then installing the battery, or holding down the button while I plugged it in with no battery, etc. I had just given up after getting it into download mode briefly for the 20th time, when I gave it one more go while rocking the on and off button. Technically that is recovery mode, but I let off right before plugging the phone in and it hit download mode and stuck.
So what I am thinking is the power button got jammed internally. I have heard of it happening on other forums. Even though it looks good and clicks upon external examination, the pressure circuit on the inside might be in contact. Anyway, just one theory.
For future though, I did discover that you don't HAVE to have the USB unplugged prior to getting into download mode. On the contrary, a power source must be present in order to register that the keys are pressed PRIOR to initiating USB input. Thus, you can actually remove the battery, plug in the USB (power source), then hold the volume keys while replacing the battery. Goes into download mode that way, too.
Will keep you guys updated. Might need a bit more help if the phone starts acting up again.
At this point, if the Download mode still holds ok, should I consider CyanogenMod, or is it easier to get back a good ROM from stock?
icenight:
Thanks for the reply. I don't understand much about smart phones or how they work, but trust me when I say I have had AMPLE experience with electronics, circuit boards, hardware, etc., particularly in the computer/laptop world. I code quite a bit of websites, and understand almost all things networking and OS. Just never really got into it with the phones.
Getting super excited to see the sheer amount of modding you can do though. Would love to break into a hardware modding world if it ever comes available. That's where it's at with electronics for me.
Well glad u got it sorted, lucky guy you are lol.
As for boards and the like, if it didn't work I would've suggested replacing the motherboard and/or power daughter board. But for a skyrocket may not be worth the money.
Since you're a hardware guy, maybe mess around with the phone and JTAG? Finding a way to unbrick without it would be very helpful
Since the problems started after a physical damage (fall) , I wonder how would Odin or wipe and flash might work !
Definitely a hardware damage...
Yeah, it kinda puzzled me, too. I believe the power button might have been internally stuck, but that's just one idea. Could have been a loose connection, too.
Can you lose some solid state memory with firmware on it, but the SS memory still be OK to right another copy on?
More than likely it was your power button

[Q] G2X screen not visible

Afternoon all. I know the title might seem like a BSOD post but my situation is different. I've searched but can't come up with anything.
When I turn my phone on, it completes the boot but the screen never appears. How do I know it's on? Three things, the ROM I'm using, Eagle'sBlood I think, has an engine revving theme instead of standard Android chime. Second,the menu, home, back space and search buttons on the G2X body illuminate. Lastly, if I swipe in the area where I think the unlock icon should be, the phone unlocks. If I hold down the power button and wait for the shutdown notice, I can guess the 'Do You want to shut down' and 'confirm shut down' icons and the phone turns off.
I've tried removing the battery, SD card, sim card and rebooting in each variation but with no luck. The phone has been rooted for over a year and so I tried booting into CWM (powerbutton, down volume). I think I'm getting into CWM fully but without the ability to see the screen I can't navigate.
This started happening yesterday. I was listen to Pandora and using a GPS app to track my run. The battery died during. I plugged it in for several hours but haven't seen the screen display since.
Any suggestions? If this is a hardware issue I'll get a new phone but without being able to see the screen, I'm not sure how to diagnose the problem. Other than rooting and changing the ROM, the phone is stock. The issue I had before this is the battery icon doesn't display. It just shows a battery outline with a ?-mark inside. The battery level only shows when the phone is charging and powered off.
Your help is greatly appreciated.
G2X - LG P999DW
Rooted
ROM: Eagles Blood (unsure of version)

Really sounds like a dead lcd or maybe just the backlights. I don't really know how the backlight works on this phone but typically if there is video but no light you can put a flashlight onto the screen and barely make out the display around the flashlight. Either way it sounds like hardware.
Twitch - Thanks for the reply. I'm not 100% sure what you mean by backlights though. When the phone is on and the screen is not asleep I see lights around the edges but the screen itself is black. For my own knowledge is LCD and 'digitizer' synonymous? I saw another thread describing how to replace the digitizer for $60-75.
I'll try checking it with a flashlight when I get home.

I know there is an opinion thing but what is a good upgrade from the G2x for a non-hardcore user? I rooted and changed the ROM b/c you guys made it so easy to do, not b/c I was looking for the phone to do more than it already does. Up until this, and the battery display issue, and a wifi issue I forgot to mention, I've been happy with the G2x but there is no reason to spend $100+ repairing a 2+ year old phone that I pickup used off CList in Q1, 2012 if I can find something better on the used market for $200
maurice
Yeah I'm not too sure how these phones are set up, I have more experience with lcd monitors and such. But I think it is all in one piece on phones.
If you're looking to upgrade pretty much anything that came after the g2x likely has a lot more to offer in development. Good thing about this phone is everything is an upgrade. I have a samsung galaxy s 4g that's nearly 3 years old and single core but it runs 4.3 like a boss! Aside from GPS...
Flashlight didn't show any screen images. I think the next step is just trying to guess my way into debug mode and connect via uSB to my laptop and retrieve data before dumping the phone or trying to replace the lcd/digitizer. I saw an app mentioned in another post that should allow me to mirror my phones screen on a laptop. We'll see.

Thanks again. Anyone else had this issue?
last chance
Last chance in case anyone has any great ideas. I'll be ordering a new LCD and digitizer (probably don't need both) but would prefer not to spend the coin if that isn't my problem. all suggestions welcome
Hmmm, this an odd and aggravating problem you have here lol. I've ran two versions of eaglesblood, their CM7 version on 2.3.4 and their ICS AOSP version on 4.0.4 and have never heard an engine revving in any boot animation so I'm not sure what rom you're running either. Have you tried the hard reboot? While the phone is on at the home screen (if you think you're there I guess) hold the power button and the volumeUP button and the phone will reboot. I've read on here from a more experienced user before that doing this clears or does something to the caches that makes for a more complete reboot or "reset" of the phone's condition. Try that and see what happens. The only other option I would try to take is to flash a new rom and before doing so doing a COMPLETE wipe (to include format /system) and full instillation of a new rom, gapps and kernel. Can you see any images if you boot into CWM when shining a light on the phone's screen?
Maybe I'm wrong about the ROM. The flash screen shows the android graphic in electric blue and a comet type animation zooms around. During the zooming, the sound is an engine revving. I was using the ROM for 2-3 months before this issue popped up so I doubt it is the cause just wanted to give those more knowledgeable than myself as much info as possible

That's my real problem, I can' t see anything! With the phone on, when I hit the power button and unlock the screen (guessing), the only illumination is the menu, home, back space and search buttons on the G2X body. I can tell from the haptic feedback once the phone is unlocked and I can occasionally guess the proper location to shutdown.
I tried the hard restart (Power, Up) but same result. I've downloaded an app called MobileGo for the computer that displays the phone screen but I can't get USB debugging turned on.
I have noticed another odd issue. With the phone turned on and the SIM card installed, when I call myself from a LAN line it goes straight to vmail. I know the SIM is good b/c I've been using an old nokia candy bar phone with the same SIM while troubleshooting. When re-inserting a SIM card, is there anything the user needs to do for the phone to recognize the SIM? Just wondering if this 'direct to vmail' is another sign of ............something.
Thanks
Sometimes when I take out the sim card my apn gets messed up. Ideally you'd just go into settings and load default apn and it'll work again.
But calling should work.
Seems like a busted screen from everything being described here.
Try connecting to a tv using hdmi... maybe the ROM would allow it to display. Worth a shot.

also if you could get airdroid installed on tthe phone you might be able to do something with that. Cool little app that lets you control the phone through your PC using the same wifi network.

It's alive!!
My phone is alive, or at least it was.
I followed the directions on the youtube video I found to take the G2X apart and the first thing I noticed was the corrosion on LCD connector. I'd already purchased the LCD so instead of cleaning the old we just replaced it. The new screen worked, unfortunately I couldn't get a signal so we took it apart again to clean off corrosion on all the connectors. I'll let it sit for a few days to make sure everything is dry.
Don't be a fool like me, if you're going to do anything with your phone that might cause it to get wet, especially sweat, put it in a baggie or something. I'll post a follow-up if the thorough cleaning does any good.
I'm pulling for ya man, best of luck!
It works!!
The G2X is up and running again! :good:

For anyone else that runs across this thread, unless the digitizer or LCD is physically damaged I'd disassemble the phone and check for corrosion before buying new parts. I used the new LCD but that b/c I'm not going through the trouble of returning a $16 item.
Wi-fi still doesn't seem to be working, which is odd. Wi-fi stopped working two months ago, it doesn't even show available networks, but worked for a few minutes when I originally replaced the LCD last weekend. Both antennae are connected but oh well. if I had to choose network vs wi-fi connectivity, I'll take network!
Thanks again for all the help

Finicky LCD? Other problems too

So i've been having a lot of issues with my N5 lately, mostly small stuff like general slowness, poor battery life, not surprising on an almost 3 year old phone. I also lose cell service way too frequently (not an issue with my carryer, all my friends are on the same network and are fine). Camera won't focus anymore (though im pretty sure this was my fault, probably broke it while taking it apart). I'm pretty sure the battery connector on my motherboard is damaged. I've had many problems with the battery reading its temperature as -30 C (battery heath "cold"), i've replaced the battery 4 times now and i still get that problem every now and then. Pushing on the connector fixes it temporarily, so im pretty sure some pin is bent slightly out of place and i don't know how to fix that. It recently started having this issue where just moving or bumping the phone the wrong way would cause the phone to shut off. Probably an issue with the battery connector again. I tried fiddling with it but it didn't do much.
The other day i turned it on and the LCD was backlit, but black except for one single vertical white line. Rebooted and it looked normal. Few hours later i got really pissed off with it for shutting off in the middle of an important text and threw it at the wall (not the best idea i know). Screen was already cracked so i didn't really care. Ever since then the LCD has been a real pain in the ass. i can turn the phone on but there's nothing on the screen. Ii get haptic feedback when the Google logo would up, and the notification LED is flashing like i have a message. The backlight is on and pushing hard on the cable connecting the motherboard to the daughter board i can see it start to turn on, (Google logo, few seconds of boot animation) but then back to black (while still backlit).
I can post photos if it would help diagnose/fix this, my phone is my main camera and i don't want to bother anyone if i don't have to.
Anyone know any tricks that might squeeze another mouth out of this dying phone? Any response is appreciated, Thanks!
The issues could have been related to the power button or physical internal damage. My suggestion: replace the screen with a cheap 3rd party screen if the internal components are still working. This will give you more time with your existing phone and allow you to have a working backup.

S7 - Wont start after battery&camera replacement.

Hi, my situation is; got a galaxy s7, the rear camera was bad, bought a new original one, stripped the phone down, fitted the camera, followed the tutorial (ifixit), put a new battery in at the same time, now rebuilt it all, (without the rear case on so can still easily take it apart again) and it wont turn on, wont go into safe mode, recovery mode, soft reset etc, tried every method, also via usb to my laptop, however it does charge, it comes up on the screen with the green battery icon and the LED light illuminates as if it is charging. Therefore, the screen is not damaged. And as far as i can see, all the connections are back joined onto the motherboard, it just wont boot up.
Also, if this makes any difference, I am running the Superman rom.
Any help would be massively appreciated as I have scowered so many websites searching for someone with a similar issue with a solution and I'm struggling, massively!
Are you sure you have connected the battery as required and no other circuit was touched?
Also, do you have the certainty this "new" battery works? I suggest you do the next 2 things:
1. Take this battery out and connect your old one. this way you can check if the new battery is faulty.
2. If doesn't work, even after inserting again the old battery, take your phone to a local repair center. (probably you messed something up).

I'd start by reversing everything you did until it powers on again, if it still doesn't power on with the old camera module & old battery in then start looking at other things, i'd probably start with the battery though as it is a power issue
The new battery charges and it comes up on my screen showing the green battery image charging so it is being recognised. Tried the old battery and its the same situation. I genuinely believe I didnt accidently short anything and im confident everythinf is where it needs to be. Ive just booked in to go to the samsung shop this weekend so hopefully they manage to find skmething althpugh probably end up costing a daft amount. Thanks for the replies so far

New camera module? Did you remove it to see if it is causing the problem?
I know there are different sensors, and if the wrong one is replaced the camera won't work, not heard about it stopping the phone booting but you never know
Just taken it to the local phone repair shop, lets hope they can find something with it. Keep you updated. Thanks so far.
