hi there
it looks like the logic board died HOURS (!!) after a problematic charing of one of my two LG G5s:
I plugged the phone in an USB-socket built-in an night stand. It was a fancy hotel so I did not think of any charging issue. 1hr or so later I took my phone and it was warm - not damn hot - but hot! I've checked the phone, everything was working (calling, display, gps, ...). I removed the battery and checked the battery for a buldge - nothing. I let it cool down for 30min or so and it indeed cooled down to "normal operating temperature".
But then I noticed, that the battery hardly charged while being plugged in at that night stand built-in USB socket. So I used my original charger and cable and guess what: I got an notification: "slow charinging".
I thought nothing wrong with it, probably due the temperature or the battery got fried - but I had no time to sort out the issue as I had to check-out.
During the day I could use my phone normally: double tap the display to turn on or quickly turn off/on by pressing the on-button on the back. Except: charging always said "slow charging".
As I could not fully charge the phone, the battery soon was down to 7% (normal battery usage/drain). So I turned it off, swapped the battery with my 2nd LG G5 which was at 65% battery charge level. But guess what: the damn LG G5 did not boot! It was dead! I put the battery back to into my 2nd LG G5, everthing fine. I swapped the charging module - nothing.
At Home I tried to charge my "dead" LG G5, but I didnt even get a charging LED.
I inserted a 100% charged battery, LG G5 wont turn on
I replaced the charging module once again nothing (no charging LED)
I used Isopropanol on the on-button as suggested to fix the on-button nothing
I removed the logic board, and re-assembled it with the working display and back cover of my 2nd LG - nothing
I re-assembled the "dead display and charing module" with my 2nd LG logic board - the phone starts without issue
conclusion: back cover with all elements is fine
conclusion: display is fine
one again I re-assembled my "dead" logic board with both working display and back cover - nothing
assumption: logic board dead
But how? My phone was charging - but slowly. My phone was working till I shut it down. With "working" I mean everything worked, like camera, Internet, WiFi-Hotspot, .... everyhting worked just fine.
All my holiday data are unfortunately on the internal storage chip. Photos, Memos, GPS tracks .... all lost.
So my question is, is there anything else I could try to revive my logic board? perhaps the board is not even fried, but some contact issue? But how can I determine those issues? I mean, I disassembled the LG G5 since its release multiple times I think I reassembled everything fine. But who knows? of course i dropped the phone multiple times in years and now, once opened some broken contact could fall off?
On this video
(at 3:28min)
the guy is probing the power-on button. But I do not understand anything and youtube translation is not available.
Or is it possible to remove the "data chip" from the logic board and "put it onto another logic board"? Like swapping an SSD/HDD? As the phone is assumably dead, its the last thing I would try - if I destroy it, so be it, if it works - voilà. But I don't have any Idea which chips are the data storage chips:
On this video here
(3:00 minute mark) the guy is putting back on some "chips". Could those be the data storage chips? But I do not understand anything and youtube translation is not available for this video.
How would you proceed? I also thought to make a picture side by side comparison of my working logic board and the "fried" one. To see if anything is "different" - but I have no idea how to make such macro photos.
I know, i made a "similar" post some weeks ago ( https://forum.xda-developers.com/t/...placed-still-no-usb-connection-to-pc.4292207/ ) but this concerned my now "working phone".

Hello,
I have been struggling to find a solution for months now. My problem with the LG G5 started when it complained about the bottom cover. Every now and then it would show a screen that the bottom cover is not plugged in correctly. By unplugging and plugging it a few times the screen would go. Eventually, although I am not sure if it is related, the phone stopped turning on. When the USB cable is plugged in I get a screen showing the battery is at 0% and the red LED flashes as well.
I have tried the following:
1) Replaced the battery
2) Replaced the bottom cover
3) Inspected the logic board and cleaned it with a PCB cleaner.
Note that the phone had no contact with water.
I would really appreciate it if someone knows what could be the fault.
Many thanks
Hi folks
Have an issue i think its straightforward battery replacement and ordered one off amazon already but will take time to get to me
Just wondering if anyone has same issue or can clarify /verify my suspicion
Today my wife's lg g5 was on 7% in a 4 minute window it shutdown itself since then when plugged in with several chargers and cords the phone does not charge no led indicator light either
As such wont turn on
Ive pulled battery and put back in, usb port is clean and screen doesnt turn on for anything
Im thinking the battery is just... Dead
Any comments /suggestions?
Thanx in advance
I had a similar problem. When the phone turned off itself after discharge the battery, I can't turn it on. Even after plugged charger some minutes does not LED indicator light. And after several minutes with charger, phone is ON. My old battery is bad, with my new battery all the same.
I used the oem charger and left ir for several hours. Phone got hot but no luck. Awaiting new battery arrival.
Ok so update phone is a brick nothing works phone is 18months old... Lg messed up on this one

I’m having the same issue, I’ve tried a new battery and all that happens is that the phone gets warm and the phone is complete dead. I don’t know what’s wrong with it.
I have two dead ones too here. one died in februar, the other yesterday.
No Solution found yet. Led is not working, phone gets warm while charging.
I really want to access the data on the Mainboard, i hope that someone will find a solution.
On youtube comments i have read from several others who experienced the same..
Same problem here
My phone had an argument with the toilet.
I dried it out and it booted up just fine.
Then left it charging. It got hot then froze. I striped it all down and dried it out again, but it now appears dead.
My wife has a G5 so I'm able to fully charge batteries in hers and try them in my phone, but to no avail.
If I put the battery in and press the power button, it vibrates, but no sound, no screen, not USB recognised.
I've tried everything to recover it including but not limited to:
stock charger
multiple different USB cables
plug in to PC
plug into PC while pressing volume up/down and various other combinations
4 different bottom modules (2 standard, 2 cam plus)
stripped it down completely and cleaned all the connectors with isoproply alcohol
Seems to be dead as a dodo.
I have pictures and videos of my son on there that I'd love to recover.
Has anybody successfully recovered data off of the internall MMC from a dead motherboard?
Thanks!

You can get data from your Google backup. If you had backups turned on go out to Google from a laptop and download the last backup before it died. It should have all your pics etc
Hello,
firstly i m sorry if this is the wrong section, i m new here.
Now to the issue. I have a Huawei P30 Lite with broken LCD. I replaced the LCD with an original Huawei service pack which included LCD, Frame, Earpiece, Battery, buttons etc. Basically it included everything except motherboard, charging board and coaxial cable. The problem is that after the replacement the phone is not charging. At first it was showing that it was charging without any success (% going down instead of up). After the phone battery drained, there is no charging at all.
Doing a full hardware check i noticed that there was indication of water damage on the charging port. I replaced the whole charging board. Still same result.
Reinstalled the old LCD pack (battery had some juice in it still for testing) with the same results. When the phone is turned on, i get a charging signal and the LED indicator but without actual charging. When phone is turned off i dont even get the LED indication of charging.
Steps i already took to save time:
Changed the charger. Used up to 2.1A charger with fast charge cable aswell.
Changed the charging board.
Tried both new and old battery, internal connectors etc
Cleaned the whole motherboard with alcohol to get rid of any debris even though there is nothing visible
The phone was working normally before the lcd replacement.
The phone is working perfectly with the remaining battery and was working perfectly until the new battery drained aswell. Only problem is the charging.
Cannot perform cache cleaning since battery is dead
Software upgrades, reinstalling etc will certainly not be of any help since the phone is not charging when turned off.
I am trying to avoid costly and time consuming repairs since the only fault i can assume anymore is human error which most likely i would have noticed during the repair. I cant accept that the main board died suddenly after a simple 2 part replacement and the only thing affected was the one that had water indication on it which didnt affect it so far.
I am looking for any kind of ideas since i am totally out of them.
thank you for listening.
Hey, i know its 1 year later but i wanted to ask you about this. I had the exact same problem as you with a p30 lite aswell. Did you find out where was the problem? Could you fix it? Thanks
I dropped my phone in the pool and it died. Completely dead. I also made the mistake of trying to switch it on. Two repair places said it was finished (not quite sure what these guys do, but it's not repair phones)
I dried it in rice and salt for a couple of days and it was still dead. So I took it apart, washed the motherboard in alcohol and it sort of came back to life, but wouldn't hold a charge or switch on, but was memory visible via the USB on the computer, leading me to believe the motherboard was "alive".
I took it apart again, washed the main board, charging port, dried and reassembled. It kept switching off when the screen was connected, so I disconnected the screen and charged the battery: Everything okay, can connect via usb, charge stable, LEDs doing their normal thing. I assumed the short was somewhere in the screen assembly, so changed this., I can now even boot in "recovery mode" and see the memory rather than the Hisuite thing. It even connected to to the car via bluetooth. It *even* started playing music which I suspect was a 911/112 waiting ring I must have dialled by accident since it has no SIM.
So the phone is "alive" the touch I'm guessing work, the display is brand new, light up but displays nothing.
I'm running out of ideas of how to wake up the display though and am thinking it might be a problem with the graphics card, although I don't know how to test this.
My priorities are:
Return the phone to it's state before being dropped (i.e. solve the issue with the screen)
Access data (n.b. I haven't got Hisuite installed or activated and it doesn't simply give me access to DCMI and contact which is what I care about)
Hard reset or similar to return the phone to function with data loss.
Change the motherboard (I don't really want to do this).
Hi folks,
First things first: I know there are a lot of threads concerning the "red light of death" for Huawei and other devices. I already read so many of them that my head is spinning xD However, I have some questions left and I need to distract myself from getting crazy due to the possible loss of data on my phone (and I have to wait at least until Tuesday for any news regarding the phone...)
What happend?
- Phone restarted while surfing
- Went into a bootloop
- Tried a soft reset
- Tried eRecovery --> Not succesfull
At this point I had to leave the train and the phone had turned off anyway. Wanted to charge the phone at the airport and back up recent data. Removed the protective cover and noticed that the battery was bloated. Since I was afraid I unplugged the phone and came to the conclusion that the phone doesn't work due to the defective battery. Back at home I ordered a new battery - didn't help. Phone won't turn on, softboot doesn't work. I only see a solid red LED when I try to charge it. Bought another battery - nothing. Went to a repair shop: This is the point where I start to have questions
They are all very nice at this place and maybe everything will turn out fine but I just can't wrap my head around certain things.
At first they also wanted to check for a defective battery and possible repairing errors since I replaced it myself. Today they called and let me know that the new battery is alright and they now want to order a new screen module. Later today I went to their shop to ask how much everything will cost and also to ask them about the procedure. I asked them why they want to change the display. Answer: Since the battery is fine, we believe the screen cable got damaged when taking out the old battery - its a common issue because the cable is underneath the glued battery. Once the new screen module is ordered there is a good change that it'll work and we can save your data. Note that I don't have to pay for the new screen, since I said that I only want the data back and that I don't need the phone back fully working. So I don't think they suggested it for the sake of making money.
I have indicated that I suspect a hardware problem, but the guy said the motherboard is fine. He continued to explain, that since the red LED is on and the mainboard as well as the battery are fine they assume a problem with the screen.
My questions:
How can they check if the logicboard "is ok" (I asked if they can do micro soldering and since they can't I doubt they can measure the components). Are there easy ways to exclude an hardware error on the board?
Is it possible that the phone doesn't start, vibrate, is not detected by the PC all because of a faulty screen? Any ideas why the LED is visible then?
Doesn't the red solid LED indicate charging? So how come I "charge" while not being plugged in? (LED stays red all the time)
My initial problem wasn't a possibly ruined screen cable/connection but a bloated battery. It just cracked the backcover open but nothing happened to the screen --> Is it possible at all that the bloated battery killed the display module?
If anyone has read this far: It would help me if you speculate with me about the problem, share your experiences or help me in any other way. Somehow I have to pass the time until next week and I'm going insane xD
Thank you so much!
