Hello!
I recently tried to replace my LCD/Digitizer on my S6 edge SM-G925V. Everything went well...at least I thought. The display works great! However, I believe I have either a battery issue or a OS issue.
After I installed the new screen, I booted the phone up. It loaded up fine. I went to check to make sure every feature worked. I was playing music to test the speaker and the phone just restarted on its own. I found that to be odd, and so I tried again. Same thing. This is just a couple minutes into it turning on by the way. Sometimes it would take longer to restart than others, but it was generally in the same time frame. I did try other apps to see if maybe the music app was causing it to have issues. The phone would restart randomly regardless of what I was doing.
I first thought that maybe the battery wasn't charged up enough. I charged it some, but was still getting the same issue. I then went to try and boot into safe mode. Still the same issue was there. I tried resetting the phone, master resetting the phone, and also wiping the partition. The phone now boots to the Samsung screen, then goes to the Verizon screen and then reboots in a endless cycle.
So...it was booting correctly, but randomly restarting. NOW, it's not getting past the Verizon screen and rebooting.
I tried using Odin and resetting it using the latest software update. It would pass just fine. The phone would reboot then go to "Installing Updates". It would get to 32% then say "Erasing". It would reboot back to the Samsung screen and start the endless boot process again.
The one thing that Intrigued me and led me to trying to use Odin was that when I would boot to the Downloader screen (The blue screen where you have to press up on the volume button to continue or down to cancel) the phone would never restart on that screen. I figured if it was a battery issue then it would restart regardless of what screen I was on.
But, I noticed something after all of this. The LED stays light up blue when the phone is powered off. The LED lights work correctly when the phone is on (Red when charging, changing from blue to green in a wave like pattern when turning on).
That kind of made me rethink the problem, and go back to it being a battery?
So, this is where I stand now. The phone would boot up, but randomly restart. I thought the OS may of been corrupted or something went wrong during the replacement of the screen so i tried resetting it, etc. Now, it the phone is just stuck in a endless loop. I noticed the LED lights up blue while the phone is turned off, so it has led me back to thinking it's a battery issue.
Lastly,
I don't believe I messed anything up when removing the battery. I was very gentle. I was watching a YouTube video that pointed out that thier technician poked the battery in the video, and they kept it there so we could learn from their mistake. Their battery leaked out a little and showed some residue on the black part of the piece it is mounted in. I never seen in residue or anything like that when I did mine.
I also unplugged the battery first before unplugged any of the other ribbons connected to the motherboard.
I am new to repair screens and I wanted to try on some of my old phones to get practice. Although this issue is frustrating, it is giving me a loads of knowledge on issues. It would be greatly appreciated if anyone could help me out with this. I'm not sure where else to go from here. I do have a battery ordered, but probably will not get here til sometime next week.
Thank you everyone for taking the time to read this long post!
Try replacing the battery. Make sure all grounding pathways and connectors are properly connected. Sometimes they may use unconventional pathways like the frame or a screw.
Impacts that can break the screen can cause high enough G loading to internally damage chipsets, fracture solder bonds (including hidden BGA ones) and damage internal mobo traces.
The display and mobo when out of circuit are suspectable to ESD damage. Full ESD protocols and procedures should be followed. Even though many techs don't do this doesn't mean they don't damage hardware. It may take weeks or even years to manifest itself. Handle the mobo, display and sim card like a stick of ram.
In 11 years I've only seen one tech install a sim card properly; ESD mat and wrist strap.

Hi!
Thank you for the detailed reply. Very insightful.
I've been at work for the last few hours. I left the phone powered off while I was gone. I got back and the phone is powered off, but the LED light is still blue. The only way to get that to go off is by unplugging the battery ribbon from the motherboard.
The phone was on at least 70% of battery before I left. I get back and it started charging at 20%. Mind you, it's been off while I was gone.
Do you think the safest route would be to unplug the ribbon until the new battery arrives?

If you think the battery has failed don't charge it.
Any swelling is a failure.
A sudden drop in capacity or erratic charging are also signs of a failure. I just went through this with my 10+'s battery
It's possible the battery was physically damage when the screen got broke, they're are really flimsy.
Best to rule out the battery.
It won't do your sanity much good until you do.
Examine the charge port PCB closely for any damage or solder cracks.
Examine the mobo as well. A stereo magnifying visor helps.
Hopefully the new battery will get it
Hello, I have the same exact problem. Verizon phone. Replaced screen from another phone. The phone boots normally, reaching the lock screen/home screen, but restarts after a few seconds. Performed a factory reset via the recovery menu, but now I'm stuck on the Verizon logo. Never-ending restarts. Never reaches the setup screen. The LED keeps on flashing blue-cyan at times despite forcing the phone off from maintenance boot mode (vol down + power). Tried factory resetting from there as well to no avail. Swapped back the old screen, but the boot loop persists. The battery is new (manufactured in 2020), had no random shut-off whatsoever prior to the swap, and had great SOT.
The worse part is the phone is undetectable via USB, the phone rarely fast charges. I suspect a burnt diode/capacitor on the mainboard itself because prior to the screen swap, I tried a daughterboard swap first. Both daughterboards work just fine and can handle both fast charging and data transfers on the donor phone. Both didn't work on the Verizon one. Can't even try flashing the firmware via Odin because of this.
Have you ever gotten to find a solution to this?

The part number on the daughter board must match the replacement. There maybe two US versions... if so they are incompatible.

I do have the SM-G925V (Verizon, 64GB) and SM-G925F (Global, 32GB). Originally, Verizon had a broken screen, a USB issue, and randomly restarts. SM-G925F did have a Knox-tripped mainboard and a faulty daughterboard, but only the 3.5mm jack didn't work.
Swapping only the daughterboards, I was able to use the Global just fine even after flashing the original firmware. The Verizon one despite having an older battery did suffer fewer random restarts and I started using it primarily as a hotspot device. The global one uses a newer battery I ordered online.
Prior to Verizon's factory reset via recovery menu, It had all the original components except the newer battery and the screen from global. I tried a reset because the random restart became even more persistent even while doing nothing. Now, Verizon is stuck, boot loop. I tried swapping even all the original components (older battery, broken screen) just to see if the phone will proceed to the setup screen. It didn't.
Were you able to fix the boot loop issue on your Verizon?

I know about because I ran into that problem on my N10+ N975U. Apparently there are 2 C port pcb variants. In my case the original pcb was still good so they just put it back in.
So much for preventive maintenance...

Sorry, I thought you originally posted the problem. I just noticed it was @TrumpXLV. Nevertheless, thanks for providing some insight. I did try to swap back all the original components on both of the variants, Global and Verizon. Did a factory reset via recovery menu on both, but only the Global one reset just fine and the Verizon one didn't.
I was curious if @TrumpXLV did find a solution. This is the only post I found that described the same issue, the same model. Might have to shelve this phone for now. Was planning to repurpose this phone in some way originally. I'm daily driving S10+ atm.

I have a Sprint TP2 which I have SIM, Security, and CID Unlocked (using Olipro's wonderful unlocker). I also have Sprint's GSM radio flashed. The phone has worked perfectly with my T-Mobile SIM card for the past 4 months, but suddenly it decided to break! Just last week, suddenly the phone was stuck on the HTC loading screen but luckily performing a hard reset fixed it. However today, the phone wouldn't turn on at all. I tried hard resetting again, but the phone showed no response (the screen was completely dark). I also tried a soft reset, but the phone was completely unresponsive. I can't even get it to display the bootloader screen! No matter what I do, the phone remains on a black screen. When I plug it into the computer, the orange light turns on but no matter what buttons I press (hard reset, soft reset, etc) the phone's screen remains black. I have gotten a brand new battery and put it in the phone, but this does nothing.
I've noticed that the phone emits a faint buzzing sound when the battery is inserted.
Is there anything I can do to fix this?
dude im think you are fcked, try charge the battery first. and see if the light comes greens thats mean that the phone at least have something working. after that try to get it on the boot menu to do a usb rom update, if you have some skills open the phone and clean it inside and de ram memory (next to the mini sd) any way wait for the gurus of the forum to have a better info about what to do and good luck

guess/shot in the dark: if you plug it into the PC it doesn't try to load some new USB drivers by any chance, does it?
As last chance
Try CMonex thing first, then if phone is out of warranty and definetly seems to be dead as last chance i would try to dismount motherboard and remove all the shielding covers to expose electronics. Take care to ground yourself to protect board from electrostatic discharge.
First inspect it with a glass lens to see if there's some kind of phisical damage or if all seems to be okay.
Then thoroughly heat it up with a hairdryer (set at max heat and max speed, very close to the mobo) paying attention not to blow any plastic or flex cables. The goal is to eventually restore fake solderings that may have occurred due to age or shocks. You have to be very patient and careful to heat it very well but not too much: there's no need to see tin melt, this in fact would be dangerous, just till it turns a bit shiny, some experience and understanding of electronics helps.
I tried this method a couple of times with dead phones and sometimes worked.
Hope you can work it out.

I got my sgs2 about a month ago and its been like a dream, battery lasts for a long time phone runs ultra smoothly no glitches and nothing weird has been happening, but these last few days its just been really weird.
1) it started randomly going into driving mode, i dont even know how to activate it or what it does, but i think its draining my battery
2)When i was watching a tv show on my phone it thought that there was an hdmi cable connected and wouldnt let me hear anything through my headphones. i exited it several times but it still though there was a cable connected. Then i went straight home and quit it from the task manager and it worked with the headphines but that might have been a coincidence.
3)When i connect the charger it takes a while to realize that its charging and sometimes stops charging and says that the battery is too hot or too cold but when i feel the phone it feels completely normal.
4)When i connect the usb cable, other than taking a while to realize that its connected to a charger it doesnt realize that its a usb so i cant transfer files with my computer which i do often
5)I pressed home before and it took me to some sort of clock which i imagine is for a dock but i have no such thing
6) Even after using the phone for a while and using several apps the android os has used 59% of my battery, when usually its the display that uses about 30 or 40%
none of these things had happened before and now they randomly started all at once, i havent downloaded any shady apps so i doubt its malware
any ideas?
thanks
Are you using a stock firmware or custom?
Have you tried resetting back to factory default?

seems like majority of your problems are linked with the micro USB port, try resetting your phone and see if that helps. This is weird though.
It happened once to me on my sgs but that was because I inserted the charging pin without realising it was wet but it went back to normal a few days later and I changed my charger.
i was also starting to think it would be a micro usb problem,
would a factory reset fix it?
if so how would i back up my apps so that i have the same apps with the same progress on them, is it even possible?
or should i just wait and see if it goes back to normal?
I am also having this issue now. I've tried a factory reset with no effect. The phone is now largely unusable. Did you get a resolution? If so, how?
im having the same problem too .. wish it's just a software issue!!
the problem solved itself after a couple of days, i took out the battery and left the phone alone for about a day and after it worked fine again, not sure if it was the time or leaving it without battery but its working normally again
I'm having this exact problem - phone switches into driving mode, then says MTP is connected - then it switcheds to a strange lock-screen I have never sen before. It's really strange. I flashed a nandroid backup from a few months back and still the problem is there. I'd flash back to stock and send it in - but I can't connect to Odin via USB because of the problem. Is there anyway to convert a Stock rom to a CWM flashable file?
I'm desperate to get this sorted.
Experiencing the same. Has anyone a proven solution for this?
My phone, sorted itself out - should I say my wife sorted it out - by mistake. What I think she done was hold down the home button, and then pressed the power off button together and held them untill the phone switched off. When my phone came back on again - she had somehow removed the -Exclamation Triangle of the kernel counter and removed the problems from this post - that I'd been experiencing for abouyt 5 months prior.
Go figure - I now have a SGS2 that works beautifully again and has also had any kernel counter and Custom Rom flashing notifications removed altogether. I wish I knew why this worked, as I'm sure their are many who would like to remove the Triangle without a jig.
The other option that seeemd to work for other people was to clean the MicroUSB port of the device with a dry, clean toothbrush - though this did nothing for my problem. Good luck -I know how frustrating it is.
Help Please
Guys, I am Facing the EXACT same problem.
1.Driving mode on/off automatically
2.Showing a lockscreen which shouldn't have existed on this planet.
3.Hanging up unconditionally. Have to restart phone.
4.Sudden "mtp connections" and because of that "Media Scanner"
I own a Galaxy note just 1 month old! I was so angry that i wanted to sell this. But i couldn't adapt to any other smaller screens so, guess ill try fixing this.
1.It definitely is something related to usb port (Since i cannot charge my phone, i use an external charger)
2.Took my beloved to a samsung service centre, they said phone is waterlogged and showed me the motherboard, saying"IC MIGHT be damaged"
3.Cost for repair - $200
4.Cannot afford that. I am guessing they were bluffing cause i saw the shiniest motherboard ever
5.Please fix this, or ill be stuck with a Nokia 500 !!
6.I can, however afford changing the usb connector, anyone successful with that?
Edit: Did my homework and found out that its definitely a usb port problem. Solution:Clean the usb port. Ill try try it and get back to you ppl. Oh and about 20% of the world's population is facing the same problem.
Edit(2): SOLVED!!!
1. Turn Off phone
2. Remove battery.
3.Take a Brush with hard bristles(Toothbrush/Artist's Brush)
4.Take a pin.
5.Take your own sweet 15mins to perfectly clean the micro usb port using the brush. Nicely and Tidily, give all possible strokes to flawlessly remove any dirt in there.
4.Then take your pin(Be careful here) and gently insert it into the gap between that small metallic micro slab and the bottom part of the usb Connector and gently move it up, VERY GENTLY!!!
5.Clean the battery's charging plates using a cloth, i used my own T-Shirt.
6.Put battery in and REBOOT.
7.Clean the charging pin of the charger using the safety pin/Brush or both.
I have it on for 15mins and no problems. Removed and put the charger again and again, still no problem. After waiting for 1 week, i am able to charge it using its charger! Now lets see whether it lasts......:-/
Edit(3): So, my phone acted up again last night, with driving mode and car dock. I used the pin solution, No problem till now. its Peacefully charging. Bah! it really is annoying
Edit(4): Now, its been 24 hours since my last solution, and phone hasnt acted strange. I guess after another 12 hours ill rule out the permanent solution. Which i used.
same here
Well.. I'm having similar issue. Battery drain and random driving mode/voice search sometimes. It all started after last OTA update and rooting without changing a ROM to custom. I've clean out USB port and no result. Maybe it's time to scan system with AV or unroot device...

I had the same issues 2 weeks after i bought my galaxy s2. Took it to Samsung customer care and they replaced the micro usb port. Haven't had a single issue since.
PS: Try to dry out the port and the phone if it is a water logging issue. I used a hair drier to do that. Luckily the tab that indicates water damage hadn't changed colour.
Had same issue with my Samsung Galaxy Note - randomly going in and out of driving mode, used a dry, soft toothbrush to clean out the USB Charging port, so far so good.
Make sure to flick the bristles of the toothbrush back and forth with your thumb first as you might see a lot of dust fly off of it.
Don't use anything hard like a pin or needle as you might scratch the contacts.

It's just a software problem, the reasons might be:-
1) you might have opened and closed some huge apps randomly and very rudely..
2) You are low on space on the internal MMC Card
3) Your phone might be performing the restarting apps re scheduler
Solutions:-
1)Factory Data reset will not help as the cache section might be corrupt.. neither the android 3e will help...
2) a)Use odin and download the Latest firmware package from Sammobile's Website.
b) for tutorial on flashing, go http://forum.xda-developers.com/showthread.php?t=2488942.
c) Do not touch the phone after processes and restart was observed...
d) Again get into download mode and re flash the same Firmware again...
e) Restart the phone holding the HOME key, (it won't do anything by itself)
f) it will surely fix your Phone
3) Message me if any problem persists...

I registered on this forum just to say that this is a great solution. It looks like my phone is saved now
Hope it will not happen again.
Background: I had my completely stock Nexus 5 on the charger for around an hour. When it got near 100%, it locked up for about 5 seconds and powered off. It wouldn't charge or power on again until 2 days later where it would power up but not charge. It could go to the bootloader/recovery but it would still shut down. The charger used won't charge anything anymore, it may have been a power surge that messed it up.
I replaced the battery and the system is still unable to maintain power but recovery and the bootloader are stable (just formatted the cache and the phone did not power off, took around 15 minutes). Now it won't power up again.
Any idea what the issue could be? Could it be corrupted data?
First, try another cable and charger.
Also, make sure you have enough juice on the device first, reflash stock firmware with fastboot and see if the issue remains.
If you successfully flash your stock firmware and use another known working cable and charger and it's the same.... Then unfortunately it could be a hardware issue.
Thanks for the reply.
Unfortunately, that didn't bring my N5 back to life. I'm think a circuit may be fried on the motherboard but I don't have a real way of judging that at the moment.
Any chance you might be able to guess what the hardware issue could be? I'm mainly trying to save the data on my phone and I'm not against taking the phone apart to do that.
Update: I took the phone to a Sprint store and a technician looked at it. When the tech plugged it into the charger, the phone LED was flashing red with no charging screen. It eventually booted up and shut down. Later that day, I could see my notifications (Pushbullet is a wonderful app) and noticed the phone stayed on consistently. He said everything was fine and their formal report didn't mention any sort of damage to the phone that they could find. Later that same day, it died again. Today, I decided to completely wipe and load 5.1 to the phone. It stayed powered on through the whole flashing process (bootloader unlock and individual partition flashes) but shut off during "optimizing apps". Considering it powered off in the system, I'm thinking the issue is with the RAM or the CPU possibly being fried due to a power spike while on the charger. It seems like it only happens during heavy operations.
Something hardware it seems. Not sure what, but if a component on the mb is bad then it is a replacement.
I like the title though, doubt anyone has a device that stays charged while in system. Sorry about your phone, but made me chuckle. I really can't think of a better way to describe it, not trying to pick on you.
Hi,
there are some threads about the bootloop problem, but I couldn't find exactly same problem: some days ago my phone landed into the bootloop. It was a bit spooky with battery charging state, it was jumping for different states - 3%, 99%, 24% after every loop. So I bought a new battery and replaced the old one. Now the phone starts to LG logo (with starting sound), but after 10 seconds I can hear the power-off sound and the phone turns off. It seems to be a "normal" shutdown, not the "reset-bootloop": I hear power-off-sound, LG-power-off-logo and LED is blinking blue for about 10 seconds. After that it repeats infinitely. Also, if I turn the phone off it stays off, but if I put the charger in it, it's starts from itself again and again. Did not tried the hard reset until now. Any ideas, guys?
update: tried hard reset. it's starts until "optimizing apps", if it's done, i can see for a second the "first setup" screen and then it's immediately shutting down. same problem with the old, original battery.
edit: for the first time I saw message "high temperature" on the screen, before it was powered off. But the phone is not even warm...

What you describe is exactly that happened to the Mrs's GF2. One day it was fine and then all of a sudden the battery drained really quick. Now she can only get to the optimizing apps screen before it shuts down again. Ordered a new battery but that doesn't look to be the solution from your findings. :crying:
My phone has the exact same prblm n i was thinking of buying a battery but now that i have read your post i am doubting my battery purchase.
By the way have u found any fix also are u sure the battery is genuine n not some poor replica?
I had this problem when I had flux in my battery port causing a battery connection problem. Sometimes it said temperature too high and other times temperature too low. I was able to fix it by taking out the motherboard using 90% alcohol and a toothbrush to clean the battery port in the motherboard. Then I let it dry and problem was gone. Now I'm not saying this is exactly your problem but it just means that there's most likely bad connectivity to your battery. It could be your battery, the cable or the port.
Mrs received her new battery and it seemed genuine. Put it in and the phone is 100% dead. No power, no charging, no life.
Its not all bad news as she bought a Honor 6X which is a far better phone.
I tried all the hints I could find (except cleaning it with alcohol), but nothing help to start the phone again. Could be defective heat/temp sensor on the motherboard.
Battery was from "Polarcell" - that's a pretty good one manufacturer with satisfied user reviews on amazon (also had good personal experience with their batteries). Just for info: phone doesn't even start with original battery anymore - same problem.
I already switched to Honor 9 (excellent phone!), but will give another try and clean the battery attachment port with alcohol today. Will give you an update later.
If you plug the phone into the charger does it even show the battery charging symbol at all?
From what I've been reading the temp sensor is in the battery and sends the temp signal through the battery connector to the motherboard. So if you replace the battery it's like plugin in a new temp sensor. However if the connector is bad then that's the only thing that I can think off that would prevent the phone from starting. If the port is bad I don't know if it can be fixed or not.
Had no luck yesterday with port cleaning. Still the same error.

Yes, but it's more complicated. If the phone is turned off and you plug USB in, it starts to boot from itself (without pressing the power button). In most cases it's going up to LG logo and powering off again. After powering off I can see battery charging symbol for about 5 seconds, after that it's changing to battery symbol with an thermometer. While the phone is in this bootloop, it's charging. From the point with this battery temperature symbol it stops charging. I read something on reddit about getting it up to 100% could solve the problem. So, I tried to plug it on and off about 50 times to get fully charged, got it up to 100%, but it's still rebooting. Can't get into recovery, but it's possible to get into the "hard reset"-menu, where I can wipe data. After this the phone boots normally (at the first sign), it's starting optimizing apps, I can see the "first-setup"-screen (that one with language chooser) for a half second and it turns off again. Same behavior with both batteries - new one and the original.

That's a lot of combined symptoms. I have no idea what could be wrong with yours exactly. I would try to bake the motherboard with solder flux as a last resort. I had to do that with my G flex 2 twice to bring it back to life. I'm not sure if it would fix it in your case, but at this point you don't have much to lose.

I've already spent enough time with trying get it back to life. Loved this phone, but I had to send it to LG service every half year (3 times!) and got it every time with a new motherboard back. My brother had to send his one two times within a year because of several problems (no vibration, no sound through 3.5 jack...). Furthermore it was not possible to root or unlock the bootloader since Android 6 (what I've got with the last replaced mainboard, but what was not available through the software update!). So, just for me it was a very bad experience and for sure I'll not buy an LG phone for the next 10 years.

Is your phone still under warranty?

Yes. But I think is gone as I changed the battery... But good idea, I'll try to send it to LG service again. Who knows...

Oh, that might void your warranty if you changed battery yourself. As I can see you're from Germany, EU, so you should ask for DAP (defective after purchase) act from service to get refund for your phone.
I've never heard about DAP. Do I give them my phone and get from them some money back or what is that about? Is it an manufacturer service or general refund possibility in EU?

I assume it should be available in EU. You should contact your seller or the service about if for detailed info. When you dave details about that please share them here.
Hey all,
While I was watching a video 2 days ago, the screen started to glitch and the phone shut itself down. I tried to restart it by holding [power]+[vol up]+[vol down]. I got stuck in the boot screen, then it shut down completely. I tried charging it but it didn't work. I left it for several hours and tried again, this time it started to charge the battery. I immediately tried to boot it. It booted normally but froze at the home screen, and went black again. Now, I get no response when I plug it to my computer, I can't get into download mode, and it doesn't the charge battery.
Any help would be appeciated.
See if you can get into recovery, clear system cache.
I doubt this will fix it so immediately afterwards try booting up in safe mode.
Copy any critical data, enable debugging, prepare to do a reflash.
If you installed any recent apps, try uninstalling them especially launchers or power management. They may be the cause of the boot loop. Check apps listed as system Administrator in security for anything that shouldn't be there, and disable all.
Try a hard reboot (simulates pulling the battery).
If no joy, factory reset.
If this doesn't work try reflashing to the same firmware version.
If that doesn't work you're likely looking at a mobo failure.
Happy hunting...
Please read and observe forum rules.
Do not create duplicate threads... good luck.

Most probably a motherboard issue. I experienced something similar with a brand new Note 4 back in the day. It was repaired by the seller (motherboard replacement).

The BGA chipsets aren't tolerant of board flexing or direct impact; solder joints can fracture.
The chipsets themselves can suffer internal damage from high G impacts.
Internal PCB traces can also be broken by excess board flexing, they are many times fine pitched.
A good case keeps drops survivable by limiting the G loading on the phone.
However I wouldn't write it off just yet... gentle pressure on the mobo chipsets etc with a pencil eraser or such with the device on, may reveal a solder fracture or trace break.
Also inspect ribbon connectors for damage and full contact. Ensure all ground pathways are intact sometimes these can be hard to spot or use a screw (a short length wrong screw won't work).
