[Solved]My lg shows insert battery when connected to usb or wall charger. - General Questions and Answers

Hello all! Here's my problem:
After i flashed my ks20 to a v10a rom it will shut down and display a "insert battery" animation when connected via usb or to a wall charger. I tried different roms (by flashing in emergency mode) but the difference is maybe a few minutes more before shut down.
Has anybody experienced something like this? or even has a solution to it?
Since i had no answers i did a little research and thanks to raykisi's link to the service manual i found out that the reason for this behaviour is charging circuit failure.
So if anyone has the same problem then i guess there's nothing you can do but to change the mainboard. Except if you are good enough to locate and replace the busted components.

KS20 Insert Battery
any new outcome?managed to flashed in emergency mode but when reboot the phone error with "Insert Battery"
But ok when Unplug Usb or Charger, unable to restore nvram..
hepp hepp.. Raysiki.. mayday.. maydayy...

is this 4 real? omg cant we just reflash or reinstall the windows or smth? well that sux

According to the service manual you have to change the motherboard. I have tried several Roms and the problem seems permanent. The only changes i have seen have to do with the time the phone lasts until the "Insert Battery" message appears. I hope that someone can come up with a software based solution to this but i seriously doubt it.

KS20 Insert Battery
its serious!! i just sent out one unit of KS 20 to service center, bought from some one with very cheap USD80.00, i thought i can reflash and works.
waiting still with the hope that mainboard below my budget

HELP!!!Impossible to charge the battery,permanent RED Led

As i said on the title,suddenly i couldn't recharge my Universal anymore,yes i've tried with a brend new official battery as well but everything was in vain.As soon as i plug my charge to my Universal it appear a Red Led and after 3 min or so the led turn off and so the battery.
How can i fix this problem?!
Is there any chance?!
Is it really dead like that?!
Please HHHHHHHEEEEEEEEELLLLLLLPPPPPPPPPPPPPPPPPPP!!!!!!!!!!!!!!!!
If the battery is really brand new, then I guess the connectors might be damaged or the internal power buses might be broken somewhere. Have you dropped your device recently? Or did anything that might explain broken connectors or internal buses?
Nothing happened to my device and never felt down,it just happened suddenly!Now if i won't be able to fix this by myself this means a finger in da a.. cuz my warranty is expired!DAAAAAAAAMN

It can be a software error. Have you tried hard resetting or installing another ROM?

Your battery is fine, unfortunately your device broke
Unless you have a lot of specialized equipment at home, and the proper qualifications, there's no way in hell you can fix this. I'm sticking with my diagnosis, that either the power routing circuit broke down, or a power bus inside the device.
Really, your best off taking it back to the store, and paying for the repair. Either that, or buying a new phone, and selling this one for spares...
Sorry mate...

similar problem
i had the exact same thing happen to my EXEC when i got 2 new batteries for it. One was a standard sized, pretty much the same as the stock one that came with the phone and one was a much larger capacity one that needs an extra cover for the back.
Id been using the device for ages on this huge battery and the charge said 100% constantly. then the device turned itself off and it wouldnt come back on. upon connecting the charger the LED was red, so i thought the battery was dead. I left it on charge over night and when i tried again the next morning it was fine.
this happens everytime with this battery, it just needs a much longer charge than the standard one, and doesnt register properly on the default OS, i havent tried it on my recent upgrade to one of the midget roms.
so try leaving it on charge over night or for a very long time. if all else fails just get a new battery.
That might reset the battery back to life, but I wouldn't exactly count on that. A battery with a broken monitor circuitry is pretty hard to reset.
My last hope,i'm gonna leave charging my phone for a day and then see what happend....I'm desperate
Permanent red light...
I had this problem, I put the phone on charge but forgot to put a battery in - spare phone... It wouldn't work no matter what I did , until I reformatted the DOC by following the steps in the WIKI.

Could u post it please?!
Took a while but here it is...
I did the task 28 55aa command in MTTY which should reformat the DOC alternatively you could reload the bootloader using the link below...
MTTY with "task 28 55aa", "set 14 0", "set 14 9, "set 14 10" and "set 14 20" as described. bootloader screen may be replaced with a blank one, boot it on bootloader mode by "Backlight+Power+Reset"
http://wiki.xda-developers.com/index.php?pagename=Universal_Resets
now upgrade as usual.
If you stuck on the bootloader again after upgrading, try to upgrade the bootloader itself go to http://forum.xda-developers.com/showpost.php?p=1255206&postcount=52

Exactly if my Jasjar is completely dead how can i connect via usb and then use mtty?!
I'm losing my hope to bring it back to live!
have same problem - can do nothing, still waiting
but there is one thing - led flashes once, when i put the charger into the device - but it does nor light, nor flashes - exactly nothing happens
If your device is dead...
Well just to answer the question, if the battery is dead and you can't charge it because of a red LED. I suggest you buy a standalone charger from ebay and charge the battery or get someone else to charge it for you. Then follow the steps as I stated in my previous post...

The point is that the device is dead and that is why the constant red light. I have a device that is stuck on the splash screen (no solution in sight) and another that fell down and broke. The one that fell down does not power on. If you put a charged battery ang plug in the charger nothing happens, no light comes on, but if you put a discharged battery the red light comes on. I have a third Uni that I accidentally flashed with a BA rom. It is behaving exactly like the broken uni, it does not turn on, does not go into bootloader and the red light comes on when I plug in the charger with a discharged battery in it.
For some things, there's just no cure...
Okay I understand where you're coming from but essentially what you need to do, under normal circumstances, is connect it to your PC, which if the device is working at all the PC will detect it but not connect... In the case of two of your Uni's I don't think this will help - the dropped one and the BA ROM failure. The one with the Red LED, which has stopped working could be a component failure on the board or it could be a Corrupt DOC table. Now to get back to how you'd go about fixing it if it is a corrupt DOC table, when you connect it to the PC and the PC detects it you disable ActiveSync and start MTTY it should give you the option of connecting to the USB port, when it does this if you get a prompt the problem should be fixable because MTTY can "talk" to the device... As for the other's try this method and if it doesn't work sell them for parts or canabalise the one for parts for the other...

Failing battery sensor(?), unable to boot normally.

So my issue is that my phone believes that the battery is out of power. Weather the phone is on or off it charges just fine when connecting the charger, it just doesn't show any indication. When it's on it reacts by activating the display when connecting the cord.
I found a workaround to boot up the phone though, but I'd like to be able to know what's left of the battery anyhow!
To boot up my device I have to disconnect the battery and connect the charger. That way I'm able to boot up download mode. Once I'm there I reconnect the battery and choose start. The phone boots just fine and I don't experience any issues at all.
It all happened when I switched out my cracked display for a new.
I even tried replacing the battery, as well as the flex cable connecting the USB port to the motherboard.
The only thing I could imagine be wrong would be some hardware sensor failing, but then again I don't see how that could have happened.
Is that sensor on the motherboard?
A thing I haven't yet tried is a factory reset. Would that have any impact?
No ideas, huh?

You can try a factory reset but I don't know if it makes any difference since it sounds like an hardware problem.

It's a hardware problem... Head to the service centre & let them know how it happened. They'll diagnose your problem.

Dead Nexus 5?

I just got this very neatly used 32GB Nexus 5 and on arrival yesterday afternoon it worked well except for the reboot problem the seller indicated. I flashed stock all over and rooted and installed ElementalX kernel for tap to wake and everything was going well, until last night when it just up and died on me. I thought maybe the battery was drained and I plugged it on the charger. It wasn't charging so I left it overnight. On waking up the phone is still dead. Doesn't charge, doesn't boot, nothing. I've opened it up, disassembled it to check all the parts, and everything looks fine. I also tested the battery by touching the tip of my tongue to the connector and I got the normal tingy feeling indicating the battery still has juice in it. I also checked the two LDIs and they are all still white; no water damage. I'm just at my wit's end now and considering getting another motherboard if that would fix it, but I just want to ask if there is any hope through any kind of fix before I commit to getting a new motherboard.
It might be that ?

Thanks for your response but my phone is not even booting up at all. It's just dead. Not booting, not charging, nothing. Thanks again.
IF you press power and the volume buttons and connect it to computer, did you have in device manager something?
If it was something like QHSUSB ... you can try that (it use and LG debuging software who reflash the nexus all at stock like in the factory) : http://forum.xda-developers.com/goo...-unbrick-nexus-5-stucked-qualcomm-hs-t3043301
If not it was possible that the EMMC is dead
I hope i have help you

I tried that but nothing comes up in Device Manager at all. The computer does not detect the phone in any way at all too. I think the motherboard is dead. I ordered another working Nexus 5 with a broken screen on ebay to use and swap out the motherboard.
Thanks for your replies. I appreciate it.

Fast charge not working in s6 after marshmallow (6.0.1) update

I updated my (factory unlocked) S6 to Marshmallow 6.0.1 and for two days it worked just fine. Then suddenly the fast charge stopped working. when i open notifications it says: cable charge, 5 hours until full charge. I tried everything, i have 2 original adaptive fc samsung chargers and none of them works. plus an aukey fast charging external battery, but when i connect my phone it keep saying cable charge. i pushed the usb into the charger, i turned on the fast charging option in settings, tried different cables. then i tried to connect it to my pc, but it doesnt recognizes my phone, and neither does the Mini MicroSD Card Reader that worked just fine before the update. I did a hard reset, but it wont work. im thinking maybe something (hardware) broke in the second day after the update, idk. i remember conecting the phone at night before going to sleep to an iphone cube with the battery at 90%, but that wont explain why my pc doesnt recognise it. I NEED HELP, PLZ
Just a thought: did you enable fast charging option from the battery menu ?
Please read again
it clearly says i turned on the fast charge option in settings
"5 hours until full charge"
something else is wrong here

Why? How do you know? What do you think its the problem?
the weird thing is that when I connect the s6 to the wall charger it pops up the "connected as a media device" that should appear when connecting to a computer. AND when I connect it to the computer it doesnt appear, so I cant move files, etc.
I have the same issue! I know for a fact that it started right after I charged my phone a little on my friend's car charger. I have charged my phones on his charger in the past and have never had issues. It's almost like the phone got scared and locked itself down (stopped transmitting and recieving USB data, therefore not recognizing fast charger or mtp). I have been searching this issue for a while, but have not been able to find a solution. There are lots of people out there that have this problem! I have called Samsung, but they barely even wanted to talk to be because it is the unlocked variant (sm-g920i). Honestly at this point I would be willing to pay them maybe $50 to fix it. It's ridiculous! And I suspect that it is just their dumbass firmware that screwed me over!
I also suspect that is the firmware, but i have searched everywhere and the only ones that could fix it did it by changing the usb port (therefore it was a hardware problem). The ****ty thing is that this phone is too difficult to open, and too dangerous, i dont dare to do it myself, but i neither trust anyone who isnt samsung... so.. i think im just going to sell it and buy anotherone, or idk.. if you can solve the problem please let me know. I'll really appreciate it. (Sorry for bad english)
you might want to try clear both daavik cache and cache.
. I had a similiar problem, that seemed to clear it up.
to clear the dalvik cache i have to root it, and i dont want to in case i have to take it to samsung because maybe if i root it i will loose the warranty. and i already cleared all the other caches like 5 times, i dont know what to do anymore. thank you for the reply, if you know of anything else I can try...
I can confirm that it is not hardware related. I have replaced the board containing the USB port, but am still having the same issue!
And have you found a firmware/software solution to the problem? what's exactly your issue? the same as mine? no fast charge and not connecting to pc?
I also have the same problem, since wiped the device with paper and sometimes back fast loading, however the transfer via USB does not work. I believe it is software problem.
Yesterday I noticed that my data cable connects via download mode by odin, or as may be hardware if odin recognize?
guys,i got a galaxy s6 edge and i had a fast charging issue and i've checked all common solution like changing cables,chargers,even changed the socket but same issue exits my mobile charging in 6 hours and when i go to fast charge option in menu it turned on and at the moment of connecting the cable to automaticly turn off with no choise to turn it on again,any one please knows how so solve??

Galaxy S7 Fast Charge & MTP Not Working, Computers Cannot Recognize It!!

Hi dear xda users
I have a Samsung Galaxy S7 SM-G930F model and facing a very frustrating issue. The problem began a couple of months ago, when I woke up, the fast charging ability and any USB connection with computer was gone.
The steps that I've tried
1) I have tried it with multiple computers, multiple USB ports and ORIGINAL 2.0A fast wall chargers, can't recognize it,can't fast charge.
2) I have installed ADB drivers and all Samsung drivers, still not recognized,still can't fast charge.
3) I've tried to revert it to stock with stock firmware, stock bootloader and modem, even in Fastboot Download mode, still not recognized.
4) Last thing, I thought it might be the charging port (flex) is broken and I've had it changed with the same new charging flex in front of my eyes with a technician and still can't get it recognized or fast charged.
5) I have changed the settings and tried almost all combinations from the dialer menu *#8800#, still can't!
The device did not contact any water at all and I am beginning to think that motherboard is corrupt somehow.
Another bad news is Samsung Turkey Official Service Centers are denying to repair the devices that you bought from any other country (SHAME ON YOU SAMSUNG!)
They basically won't replace or repair anything with in my phone! (still, it is the same model that they sell in Turkey)
Have anyone faced the similar issues with me?
Only thing I know of is if you have USB debugging on, it prevents some USB functionality until turned off. But if you flashed stock, USB debugging should have reverted to stock.
And yes Samsung warranty doesn't cover grey imports, you have to buy locally.

I've tried almost all possibilities and no, you got me wrong, I am not asking for a warranty covered service, even I say that I am going to pay for it, they won't do it.

You mention charging port "Flex", I assumed by that wording you meant some cable from the port
Well only thing left is the battery and main motherboard really
happened to my old s7 edge and i did all you have done too but no luck. it is some software bug i read soemwhere which only samsung can fix via ota cause our phone cant get detected by pc to flash rom. so all eforts in vain , and i sold the phone in the end. also mine used to get charged in 5-6 hours cause it detecs every cable as usb cable.

Almost everyone in this forum has a rooted phone, yet this is an issue few have experienced. Rooting might be the first step they took to breaking something, but rooting alone couldn't be the cause otherwise you'd see way more of this.
Keep it on track guys!!!!!
How are we gonna fix this! I'm scared if my phone dies and I can't connect it to a pc..
