Hey guys, had my hero for about 6 months now, bought it from a friend was working properly. After playing around with rooting and flashing custom roms my USB has decided to not work anymore, I can still charge the phone which isn't so bad but can no longer mount to pc, can you guys think of any suggestions to what it might be?
Same here. No idea how to fix.

what rom are you using?
could be rom related
I've tried flashing different roms and it still seems the same, I'm using Tegro, but it worked fine when I first flashed the phone
have you been try this one try this one
connect your phone to the usb port of your pc.
while the phone is still connected, turn it off and turn it on (remember do not unplug the phone keep it connected to the pc).
as the phone is done with the booting process you will get what you wanted.
After a few weeks of putting up with my USB issue I have finally got it to work again. All I did was use a standard wall USB charger and a USB mini cable instead of using a Motorola charger. But so far after using it all day it has seemed to fix it

Tried on several PC's so it's obviously a phone issue, went through all 3 Port Settings in the MFG app, no change though, i can only charge the phone and that's that, any other ideas ?
Already tried factory reset too
No one ? I just realized that i can't even copy my music anymore lol..if only i had wireless sync setup before this happened..
Even deploy doesnt work right? Maybe you have messed up something in registry...do you remember recent changes?

I don't remember changing anything besides the usb settings, and once i think i tried to unlock it or even succeeded but this shouldn't interfere with the device afaik
I'm looking at a semi-bricked phone now
I didn't try to deploy but since the phone is not recognized anymore i don't know if there is any chance or ?
Just an update..yesterday while i was cleaning up my desk i found the original LG cable that came with the phone...i plug it in and what do you know...the phone is recognized again...there are no words...
What kind off cable was the ``other`` one ?
I think i tried with 3 other different cables, one came from a Blakberry, one from HTC Desire and one i don't remember from
I have had both the Samsung Focus and now the LG, while I haven't had this issue with my LG, I did with the Samsung.
Same thing, tried every micro cable I had, and none of them worked, finally found the orginal cable and it worked. ... I know it's common on the Focus, but the first I've heard on the LG.
It's very frustrating, especially since i'm a "tech" person and couldn't find any solution to this, being forced to use the original cable makes no sense even now but i hope that at least someone else who will face this will find this thread useful.
so I bricked my verizon VS980 upon flashing a rom, not realizing how long it would actually take, getting impatient, and holding down power/vol-. the phone is stuck in a bootloop. i can get into download mode. i have tried these:
http://forum.xda-developers.com/showthread.php?t=2432476
http://forum.xda-developers.com/showthread.php?t=2448960
both of which became dead ends. i have tried reinstalling drivers, rebooting, different PCs, and different usb ports/cables. device manager shows this regardless of the phone being plugged in or not:

(unknown device is unrelated)
I'm pretty worried about my USB port being broken, although it would surprise me if that were the case.
it might help for someone to explain com ports to me; i was under the impression that for a PC to see a usb device plugged in via COM, it would have to be through a usb to serial adapter, which obviously isn't the case.
i think i'm still within my return period, but i'm probably not within the warranty limits.
been working on this quite awhile and i'd really hate to have to sell the thing.
thanks for any help!
Hello everybody,
- On monday i ran into a strange problem with my N910F. At first it was just not charging whatsoever.
- after the phone ran out of power, i attempted to charge it which gave me a brick with a black screen, vibrating short every two seconds
- Fine by me i thought, went and got a replacement battery (after checking simple stuff like the physical state of the battery (normal) and killing the batterystats (which i heard both yay and nay about so i decided to give it a try).
- Replacement battery charged overnight on the USB Port of my computer (2.0, for the completionists) went smooth (didn't turn it on, just had this bubble animation of charging).
- Turned it on this morning (booting apparently took 3% off my battery) and all well so far.
- finally in my chair at work i plugged it into my power cable (genuine Samsung FastCharging adapter that came with the phone itself) and nothing happened
- tried another adapter (some cheapo 1A adapter) which started charging around 10secs after connecting but decided to stop charging after a couple of minutes
- some shaking and gentle knocking brought back the charging symbol for some seconds, seemed like some loose contact or a broken cable so i felt fancy and plugged the very same cable (the one originally shipped with the phone) to my laptop. started charging instantly and no shaking or knocking stopped this (so no loose contact or broken cable at all)
This is the story until now, put together as complete and organized as possible. For now i'm stuck to charge my phone on the laptop or computer which seems to work. In this progress above i tested around 7 chargers, 3 laptops, 2 computers, 10 cables and 3 screens with both batteries, although the workaround i have now is only tested with the genuine cable as i was just done with testing for the night.
Now for my questions (apart from a touch with the magical fix-everything tool):
- What i see as possible causes based on my very shallow knowledge are either the microUSB port on the phone or the power distribution unit. Anyone has an idea what to check?
- As i have no idea how deep the OS goes, could it be a software issue by any chance?
Even though the device is only ~9 months old, I don't like the idea of going through Samsung for this one as i tripped KNOX already.
Hope there's still hope for me
Cheers,
Fachtal
sooooooo, does nobody have an idea lying around somewhere?

You seemed to have tried using the cheap charger which allowed you to charge after shaking it a bit, have you tried purchasing a new genuine charger?

Tripping Knox does not necessarily mean that you've lost warranty.

I tried around 7 adapters (from cheap ones to genuine galaxy S3, Note2, and Note4), around 10 different cables (again, from cheap ones to genuine samsung cables), 3 Laptops (again with all cables), 2 computers (all cables) abd one of those mobile charging battery things.
The only thing that works is either the genuine cable on my computer or the same cables on my screen at work.
@geevh that's news to me. As far as i heard is tripping know equal to losing warranty.

Have you tried to flash stock firmware, in case it's the kernel?
KNOX warranty shouldn't void your warrant in the EU as I have gotten two knox tripped devices repaired from Samsung before.

I just flashed the official ROM using Odin. Had some problems getting the phone connected while in DL mode (didn't work at all while in normal android mode).
This seemed to be a dirty flash (already was on stock Rom, just put CWM on, rooted the phone and replaced the kernel to have SELinux permissive for Viper4Droid) as it didn't go through the setup process and was like before.
Anyway, charging still doesn't work. Is there anything else I can test? I'm nearly at the point where I migrate back to my old SGS3 and have the N910F sent to the carrier (well, in the end it will go to Samsung) to get it fixed.
Thanks about the whole Knox false knowledge.
Cheers, Fachtal

I would just give the device in for repairs but make sure to flash a full stock rom and factory reset before giving the phone, since you have already tried everything else.
Good luck

Well, flashing stock ROM seems to be slightly less relaxing than I thought. It feels like I have to connect the phone to the pc, put it on the table in a very specific position/way and then hope that it doesn't disconnect halfway through flashing...
This has become quite an adventure so far and I hope I'll get this done so i can get rid of this very expensive paperweight
Thanks for all the help so far, I guess I'll add the explanation from my carrier/Samsung as soon as I (hopefully) get my device back.

PMIC or Charging IC is probably broken on the mainboard, i hear more N4's have this problem.
Best is to send it for warranty or let the components be replaced by a "good" repair shop.
Most service centers don't check knox status so i would go for that, if all fails take it for repairs if the costs are not too high.
Hi guys, back for a rather unexpected "solution"
When i finally freed up some time to actually get to the carrier shop to get my phone fixed, I was in for a rather embarrasing experience.
The lady in the shop pulled a charging cable and an adapter out of a box, plugged my phone in and it suddenly charged as if nothing ever happened. Now, some time later, it still works perfectly fine, as if there never were problems...
I have absolutely no idea on what happened. Before going to the shop i obviously flashed the stock rom yet again (with the usual wipe user data/cache/dalvik procedure).
Now, on what i had when the problems started: stock BOC5 ROM, touch CWM, rooted and with a custom kernel for SEAndroid permissive (emotion something i believe the kernel was called). Now during my rather extensive troubleshooting I actually flashed the stock ROM at least once and the issue persisted, which is why i just stood there, staring on my charging phone, my jaw somewhere on its way to the ground, unable to form any proper words :silly:
So basically, does someone have a possible explanation to clear this up? If not, I'll consider this thread solved i guess^^
In the meantime, I downgraded to Stock 4.4.4 with CWM, root and xposed (which i really missed on Lolli) and I'd say I'm happy with this :victory:

It's sound strange but a couple of years ago i read somewhere,forgotten where and about the specific device. The thing was that phone wasn't charging eather ,and now it comes.....the solution was turnig around the charger in te power socket.

this indeed sounds strange. And honestly, i didn't pay attention on the orientation of the power adapter (although my stock samsung one is always in the same orientation because the cable goes out on the side (which means it worked in the same direction as it didn't before).
The only even remotely considerable approach would be that the custom kernel along with this synapse app somehow screwed with the power intake and i forgot to wipe everything when i first flashed stock over it, meaning that synapse still had its fingers in the system screwing around with that.
But then again, as I seem to be the only one with this problem and this custom kernel had more than just a few users I don't think this is the way it went (I don't even use an unusual collection of root Apps which could cause some sort of malfunctioning combination of effects).
I had a few evenings just thinking about this and draw some simple mindmaps/schematics to make some sort of a sense...
Hello guys,
I have a LG D802 unlocked and noticed that it wont transmit a voice during the calls or record anymore, so official LG service changed my flex and voice issue has solved but!
I recognized following things afterwards;
-original usb cable recognized as usb charging, 200-300 mA while using original cable and charger. (8 hours took to full change )
-any windows or linux system can not recognize my beloved g2 anymore, even in com ports.. I tired everything in software base..
-interestingly I can enter download mode while my g2 connected to AC charger, so it is strange.
What do you think guys, LG service member thinks there might be issue in processor but it is ridiculous
Tell me your opinions please ?
(I have the "replaced flex" but I havent tried to replace with new one)
Looks like they have damaged your motherboard. I've tried replacing the Flex on my LG G2 twice, and this problem wasn't solved. Slow charging+Can't connect to any pc. My phone is stuck on jellybean forever as there's no way I can root and install TWRP without access to a laptop. Good luck.
I brought my G2 D802 in the exact same state by replacing the battery myself. I think I broke something while trying to remove the old one, wrapped in those flex bands. Looks like that cable is easily damageable by design.
Not everything is lost in my case, as I had TWRP installed prior to this mishap, but the slow charge is a real pain.
Sorry I can't really help with an advice. This phone will die as it is, not worth paying for a repair.
