Hi
I've been having a problem with my G4 for the past few days,
when i connect it to the wall charger it recognizes it as if it was charging
via USB not AC as it did normally, and when i connect it to my laptop it charges,
but won't let me use LG Bridge nor LG UP , and im not able to browse the internal memory
I've tried using several chargers and cables in several combinations with the same results ,
it only charges as AC with a no brand 1000ma charger that i had lying around and whatever usb cable i put on it.
is it possible that the usb on my phone is broken? or could it be something else?
already did a 3 factory resets and tried to flash a diferent firmware
but that's how i realized it didn't work on my laptop either.

and are the drivers installed? was it working before .? weird thing is you said it doesnt worked in another PC. make sure drivers are installed and i guess the usb cable could also be the cause.. it has happened to me that it wont recognized to transfer files. only way i solved was reformatting my Pc install drivers and voila.. but first make sure as its not working in anothe PC.
just tried on a third computer and nothing
all computers have drivers installed, tried several cables, i don't even care about connecting it to a computer
i just want it to charge normally with an AC charger

i tought you said it charges, but you cant browse files . then it must be something wrong with it. i guess send it in for repair or contact your retailer. or carrier.

yes if i connect it to a charger or to my computer it charges,
but when i connect it to an AC charger it shows up as charging as if it was connected to a USB port
so this makes it charge very slowly , taking hours to charge with a 2.0 qualcomm quick charger instead of a few minutes
when i connect it to any computer it charges but i can't browse files or connect using any software
i tried using several chargers , the stock charger that came with the phone, one from a G3 , a QC 2.0 charger, several samsung chargers, and others and only one shows as AC charging.
so yeah it charges but not as it should

did you tried ampere app from PS. so you flash back to stock using stock firmware. and samething. what variant you have.? its very weird. but the best thing to do is if u are under waarranty send it for repair...
my story its different. i have original charger.. i use ampere app adn measure and its a 1.8a stock G4 charger, when i use another Lg charger i think its 1.2 i get more voltage with the 1.2 then 1.8 i switched usb cables samething.. very odd too.

i have had the same issue i have been able to solve it (luckily i am trying to update to mm via lg bridge it gives an error after which my cell doesn't show on pc neither it charges as an ac via wall charger so heres what i did)
you need to do exactly as described
1: connect your cable to wall charger(mounted to socket=on) and mobile
2: turn off mobile(do not unplug cable until mobile completely off ~10-15 sec)
3: unplug cable after off
4: press power button and than insert cable (within 4-5 sec)
5: let it start (it should b on AC charging)

only way is to take it to telcel and have it fix. or search i have no idea.
just as an update, i took the phone to my carrier, to make a warranty claim, see if they could fix it, they sent the phone to LG and returned to me, said as i have the camera lens glass broken the warranty was void and they wont perform any repairs on the phone as it was cheaper to get a new phone, also they didn't tell me what the issue with the slow charge was, im under the impression that they only saw the shattered camera glass and said F**k it
im not sure if taking it somewhere else and replacing the usb port will help somehow

When the phone is off and plugged into the wall, it charges. When the phone is on, and I plug it into the wall or computer, the phone doesn't know it's plugged in.
I ordered a brand new usb charging flex jack and replaced the old one, still the same problem. What gives?
EDIT: I am stock. Not rooted.
Does this happen on the original cable also?
Have you tried wiping?
Is Fast Charge on?
Fk. It doesn't even charge from the wall! When the phone is off, it has the animation that says it's charging when i plug it in the wall. I left it plugged into the wall overnight. This morning I took a look at the phone, and it didn't charge!
Oh noez, what should i do?
Also, I don't have the original cable. I'm using an HTC one.
EDIT: Dafuq?! I found an LG charger. Apparently the phone knows that it's charging when I charge with that. The thing is, that charger is just a charger; it's not a usb cable+ an adaptor. So I can't use it for adb and such.
What is Fast Charge?

You should mention what ROM you're on (and version) so that no one else makes the same mistake I did in assuming you had a custom ROM and that Fast Charge is on. It's a feature that makes sure that whatever charges it is recognised as AC 1amp charger as some chargers aren't designed well enough (I believe it involves a single solder point) to report themselves as capable of 1A. If it doesn't report as AC to Android, it will charge at 500mA instead (it assumes USB power). It sometimes causes problems with connecting to PC via USB.
Get another USB cable, this time none of that fancy **** go straight to OE Samsung or something.
=O I thot all usb cables are made equal! So I can't use an HTC usb cable? The dude didn't sell me the phone with a cable T.T
Also, I'm stock. I am not even rooted.
My nexus just started acting stupid when I plug it in also.
Mine sat in a drawer for a few weeks and when I plugged it in to charge, it wouldn't.
What I did was this.
plug device into charger
remove battery for a few seconds
replace battery
press power button
phone powered up and began charging.
Even now, it still sometimes doesn't recognize the charger and I have to unplug and plug it in until it does.
I use a rocketfish cable.

Some devices are picky, you'd think that all USB cables are made equal (I did too) but some just don't work well with certain devices. I've had printers th... wait printers always have **** problems... I've had uh... usb extensions not work well with some Wifi dongles and such. My old milestone didn't like the Samsung cable either (yet the Moto cable works perfectly on gnex)
=O. Then it has to be the usb cable! No way it's not!
I ordered one on ebay =D
Rooted Gnex here I come!

Thank you dmappdev,
I followed your procedure (feel like talking about surgery here, which isn't too far from topic); I'm convinced that it helped in some way, directly or indirectly... as at first, my Galaxy S Advance still wouldn't recognize/charge my phone with:
1. its own charger,
2. my old Galaxy Ace's charger,
3. a universal wall usb plug used with the S Advanced own USB-to-USBmini cable.
My last idea was to use, quote: an old Nokia USB cable connected to my PC... and that worked.
I was much too happy my phone had remembered how to charge to stay mad... But I still tried those three means for charging again, and only the phone's original charger worked now. So the phone's charging ability has been "awakened" in some way, but only for the original charger ...technology is improving, but not the ethics on making life easier for the consumer.
All this was yesterday. This morning (there's more, yes), I saw my phone indicating a 100% charge although it had been disconnected from charge for several hours - something that had already happened once yesterday, before the unable-to-charge situation; a simple reboot took care of the problem, the battery status now showing a more realistic 53%.
Any comments to any of the above? If not, thanks again for your tip anyway !!!
I have a weird problem with my Note 2. Recently my phone was repaired ( changed Display and Main board)
working fine at today Afternoon, but now my phone is not charging with my Stock charger, my brothers phone charge with my Charger but my Note 2 wont. I tried his charger and it works, then I connected my phone 2 pc with the same usb cable I used in my charger, and it charge but pc cant recognize my phone, Same cable work for other phone and charger also work for other phone.
I Factory resetted my phone but not working Switch off, Battery pulled out. still not working.
Do I hv to Reflash my phone.
I'm downloading DN3_v5+ rom
I'll try this one.
But it will take around 4hrs, and what if it wont work.
Plz Guyz Help me
It sounds like your USB port on your phone is messed up. A lot of times with a bad micro usb port it will either not charge but sync data or it will not sync data but will charge. Also this goes for the actual usb cables as well. If you use a known good usb cable and it will either not charge or not sync dats on your pc, then it's most likely your usb port on your phone is bad. Even the refurbished devices sometimes will have bad ports that were not fully tested before passig QC so this is what I suspect is going on with your phone.

I've heard a bunch of people having this problem. My temporary solution was buying an additional batter w/charger for battery. But the usb flex cable I repaired myself last week. The part was $11.00 and the tools to pry apart and unscrew the phone were about $10.00. There are several tutorial videos on YouTube that guided me through the process.
Does anyone know why it takes so long to charge?Im using stock charger but from the battery log says 304 and I was rold my phone thinks its using usb to charge any ideas?

not sure if you have tried this, but make sure the usb charger is plugged into the mains charger all the way in...mine was the same, saying usb charging and it was the cable itself

Yep. For some reason LG decided to go with a USB charger for the phone rather than straight to the mains...
Mine takes about 3 hours to charge fully, when plugged in, locked and connected to WiFi. You have to remember, the G3 has a big battery, bigger than some other phones, so you have to expect it to take longer. I plug it into my USB 3.0 port on my PC when I'm on it and it seems to charge faster (Although my motherboard has the option to turbo a port for charging so it may just be me).

Could just be that LG has set the phone up to detect all chargers as USB considering it comes with a USB charger...
Not sure if that's the reason why but it very well could be.
Hey Guys.
Now I am PE ROM 9.0
And from yesterday I can't charge the phone by Ac Adopter.
Eg I have Qualcomm 2.0; Mi charger 2.A ; & Original Lenovo Charger.
(My all charger are working.)
I can't charge the zuk z2+ from yesterday.
But I can charge from power bank Syska 10000 mah. 2.A
Why ?
What to do?
I again clean flash this ROM today but problems is not solve tell now.
Changing the usb wire I have done
(Local wire , then 1+ 5t , Amozon classic wire ,
But tell now I can't charge the with direct Ac Adopter..
It just shows charging symbol. But no amp.

You have exactly my problem. Your usb controller is burned and it can no longer charge with 4-5 volts. It needs more. I can only charge my phone with QC-3, which outputs 8-9 volts, but your rom must support higher than 5v charge. You also won't have any access to PC, including fastboot. And unfortunately, to fix the issue, you will need a new motherboard, which doesn't make sense unless you are on warranty.

You can probably install one of those stock roms that includes older firmware (look for official TWRP installable roms on europes fans forum). That should lock your bootloader. Just be careful reading description and directions.
I'm certain that this is a software issue, because it happened out of nowhere and the phone barely two weeks old,I only charge it on the provided charger,I don't have warranty bc I bought it as a reseller,I'm thinking of installing miui.eu to see if it starts to fast charge again,because I can't wait hours for it to charge.
The problem may be in the charger even when it is new.
You can try factory reset. How version do you have (EEA Stable ROM V10.2.9.0.PFBEUXM)?
https://mirom.ezbox.idv.tw/en/phone/grus/
Try to push the end of the cable further into the charger.

Yes Mi Flash (fastboot) need unlocked bootloader. But you can install stock non fastboot version from https://c.mi.com/thread-2265065-1-0.html. I don't know where you are from, but I would use http://bigota.d.miui.com/V10.2.9.0.PFBEUXM/miui_GRUSEEAGlobal_V10.2.9.0.PFBEUXM_432d8a9116_9.0.zip

Did everything i could with a locked bootloader,this is pathetic...
Edit: With a 2.1A normal charger i got 900ma,its for sure a bug right?
Have you tried:
1. A different USB A-C cable - sometimes minor cable damage can cause a low charge throughput
2. A different charger & cable completely
3. A different socket in the house

Wow, so I'm not the only one with that issue. For me it started about month after receiving the device. Quick charge stopped working along with USB connection to PC. But surprisingly USB connection in TWRP worked fine.
I pushed and pull the plug several times and tried to move it a bit right and left and the issue was gone for about two weeks.
Within those 2 weeks quick charge was working every time I connected charger. Then suddenly it stopped working on 27 July. No updates made, the same cable and charger.
I already tried 3 different chargers and cables and it still doesn't work. I will try to flash stable MIUI in fastboot this weekend to bring it back to factory state.

I think the device is kind of thinking its at 90% and naturally slows down the charge

Okay so i did a fastboot install of the rom and its the sane,so i Just gave up...
My "Quick-charging" is also slower on 10.0.3.3 than on 10.0.3.1. Although i can see the "circled flash" icon while charging, but the charging power only reaches 8W instead of 17W before (also my USB-Meter is showing, that the QC3.0 protocol is used during charging, but as i said only at 8W). Should be a software bug.
