I've a problem after (more than one) firmware update....
My P970 don't recognize recognize charger & don't go in USB mode (PC don't view the SD card)
I try CM7 and Nova, I also have a brick after flashed a kernel Nova in a Rom stock.
After that I put a new Rom stock v10c by KDZ but now have this terrible problem....
How can I solve it....?
Many thanks
have you tried to do an hard reset?

Yes by enter in the hidden menu (3845#*970#) but nothing change....
I have the same problem since 2 months. I'm currently with the last temasek Kang release, kernel nova 11c.
The only way to charge correctly the battery is to wait the phone self extinction, by low battery, wait around 10 minutes, and plug the charger. Another weird thing: when I plug the shut down phone to sector, it will autoboot (everytime).
Else, when I try to charge the phone, 2 different behaviours:
1) most of time it charges anyway, but not detected as charging. The phone overheat, and could self extinct because of that. Time of use with a battery charged like that is very poor.
2) sometimes, nothing happen. No charge.
I'm very bored by this bug.

Check your USB cables, the pins inside. As well as the USB connector on the phone itself. Use a different cable. I/we never had this kind of problem (not charging so it isn't a bug or something but rather hardware problem. If not USB, battery problem.
If not, do a full wipe and reflash the KANGed RC0. If problems persists, revert to Froyo stock so you could test. I'm after the warranty for you if you still have the problem in Froyo.
That auto reboot is well known for CM7. Again, this also is not a bug but a feature.

Checked with 3 different cables and several chargers (including original ones). Phone USB connector seems OK, but cannot really check it.

Did full wipes several times, but no effect. It's hard to go back to stock Froyo without phone-to-computer connection, and I don't want to loose ability to root my OB after that.

OK
Anyway, thanks for all. If we are only few people with this bug, it seems to be a material failure indeed.
I may look for the warranty, but as I changed country (from EU to Canada), it will be quite complicated, and I need my phone :/. Just a (stupid) idea, maybe the phone didn't support the 110V, after 220V charging usage (but charger should support these 2 voltages).
If not, do a full wipe and reflash the KANGed RC0. If problems persists, revert to Froyo stock so you could test. I'm after the warranty for you if you still have the problem in Froyo.

I come back to v10b europe, across a lot of wipe....
Fortunatly the charger was recognized....
The problem was't "don't charge" but "not recognized"
Unfortunately today try to flash the Quasar kernel, and now I have the same problem.....
The charger, charge, but don't recognized and the USB to PC don't work's.....!!!
Turn phone off
Remove battery
Wait 10 seconds
Put battery back.
Turn phone on
I had this issue on my Optimus Black with stock Froyo rom.
My symptoms were:
- device recognized as 'modem' in Windows but no option in Android to switch into "USB Mode". Phone update software would still recognise phone was connected and I could run a firmware recovery using LG tools. Reflashed and reset to factory many times didn't fix the issue.
- if phone switched off and plugged into charger or USB would go into "SW Upgrade" mode
- I could force "USB mode" to appear on the phone by opening the hidden menu and switching the USB to "AP Mode" I think it was.
- I found the USB connections would disconnect after a period of time and sometimes the "AP mode" workaround wouldn't work.
- tried different cables, chargers and PCs and all present the same problems.
- having the battery unplugged for an extended period would get the phone working temporarily but the problem would come back after a short while.
Eventually got on to LG Support and sent it off for repair. They replaced the motherboard as faulty.
I think the problem may have been caused by a faulty car charger that I have since replaced, but ultimately replacing the motherboard on the phone fixed the problem.
If your phone is covered under warranty, I'd be sending it off for repair as it is probably a hardware issue.

Ask no Problem
I'm having same problem as stated by others. This is annoying me.
Its just been 2 months I've got this phone and it feels real bad to face such problems so soon.
Am facing problems like. I connected my phone to PC via USB and it showed me the option to Turn on Mass Storage, I clicked on it and it showed me the Mass Storage Drive on my PC too. But in just minute or two it disconnected on its own and SD Card started scanning and again it got connected by its own but then after that it disconnected again and it on pc it started to install drivers again. Which were already installed like 5 or 6 of them.
I formatted the phone twice. Removed the battery for around 5-6 minutes. Used like 4 USB cables. Installed LGE drivers from LGE Software updater.
This is so bad.
What software are you guys using? Which ROM?
I've also been experiencing this situation, one time this problem caused a loss of all my SD data! (my sd card got corrupted)
I'm on Zeus V6.11 right now, and I must say that USB storage is working great for me in CWM Recovery, even though it doesn't work on my phone when it's turned on in Android.
How to check whether it's an hardware problem in my phone, or just a fault of my compuer?
Experiencing this problem for around two months now. I suspect my charger to be damaged. Since I can charge the phone via the USB port. When I try to charge the phone via the charger it doesn't respond, but when I pull it off the charger the phone will boot. Had the motherboard already replaced by LG service center, but the problem wasn't solved.
The phone can connect to PC without any problems. PC can connect to mass storage.
So now, I'm using a Corby II charger and it seems to do a great job at charging my OB

Currently I'm using Stock Root v20b rom.
No software's nothing, as I stated I even formatted my phone twice.
It was working well around 2 days back. I had just plugged my usb cable to phone via pc and then all of a sudden the phone started acting weird, like it was connecting and disconnecting frequently, and then it started to install the LGE drivers by itself, which were already installed didn't even touch them nor uninstalled anything.
Tried using Sony Xperia Neo V's USB cable too, but no luck.
Once I lost my USB cable.
then i brought a cheap uUSB cable. Icud transfer data from PC, but charging rate was really very SLOW... nearly 4hr.!!
Now i replaced it with new Original one, n every thing working Perfect...
I am seeing the same problems - charger is not recognized and USB mode is not working. Different cables / chargers, different Win7 and Ubuntu PCs.
I formerly used a rooted V20o from here, with which the problem first appeared, now I went over to Zeus 6.22, which still shows the same problems.
I believe the hardware is faulty.
Can anybody help me how to regain warranty? I have the stock V20o (unrooted), but since USB does not work, I cannot flash it the regular way. Is it possible now to flash from sd card?
Try with LG standard update software, you have the emergency menu....
If you want to viwe your sd card try the Samba Filesharing app. I have the same problem on cm7 and with this App i can see my SD Card
Hi All,
Just purchased S3 LTE around a week back and noticed that there is an issue on charging the phone through a USB charger.
This handset came with Jelly Bean OS and had the version as 4.1.1. I purchased a third party USB charger and when connected from my Laptop to the mobile, it does not charge and nothing happens. However after experimenting, then noticed that if I restart the handphone then the charging automatically starts!
I believe this must be still an open issue in this version of handphone. Correct me if I am wrong.
If anyone has any solutions to overcome this issue, please share it with me here. I would highly thankful.
Thanks!
This is the first time I have heard of something like this
Phones have a minimum voltage required to charge them so it is probable that your computer is not supplying that
Try a different USB cable (may be faulty) and also try from a different USB port
It should work flawlessly when plugged into a power outlet
If it still doesn't work them do factory reset and if all else fails then warranty the *****

Hey everyone. Been using the Z1 for a while now and ran into a strange problem two days ago. For no apparent reason, my phone stopped charging unless it is plugged into computer that was turned on. If I use any normal charger, it doesn't recognize it. If the computer is off, no charge. Only when connected as MTP does it charge. And charging via the computer's usb charges much slower than it used to. File transfers and everything also work fine.
This happened shortly after I upgraded from the old momxdified to the newest version. Thought it could be firmware so I did a full clean flash of the stock 534 ftf and no luck. Did repair in PC Companion and no luck. Now I'm thinking it has to be hardware related?
I can now sometimes pick up a charge if I use a cheap wall charger with a very low power output. But only sometimes. The stock Z1 charger doesn't work at all.
Figure I'll go to the service center later, but wanted to check here first in case anyone has seen this or has any ideas.
Cheers

Sounds like a hardware issue, but try a hard power down, volume up and hold the power button down until you feel multiple vibrates, power the phone back up and see if that helps.

Thanks for the response. Tried that before going with the full wipe ftf flash or pc companion repair, and no luck. Finally took it to the service center today and they spent an hour reinstalling the software (no doubt doing the exact same thing I did twice before bringing it to them) then offered to replace it. Just going to miss the old Z1 for the next week, when I'll have to rely on my old S2 to take pics of my engagement celebration this weekend.
Appreciate the response and suggestion man.
I had similar problem with non original wall and car chargers because the output was to low so the phone do not recognize them at all. I didn't test the phone with the pc yet, I prefer take out the SDcard and copy anything what I need directly. I hope don't have this problems anymore so I will use original chargers only.
EDIT: SDcard not simcard..
Hi.
Recently (about 3 days) I've got a weird problem. My Xperia Z charged fine when is connected through USB with it's standard USB cable (The one in the box). But when I use that USB cable with wall charger nothing happens!. Funny thing though if I pull the cable out of xperia Z Charging LED blinks! I used several other chargers/USB cable but none of them work with my wall charger.
I have no idea it's software or hardware problem and since charging with USB takes hours it drives me mad.
please help me

Is the output of the charger enough? In A's?

It's the original Sony xperia z charger.
But in case of charger problem I use several others with no luck. Funny thing though : all of those chargers worked before without any problem.
If it is software problem I could wipe all data and factory reset or even update to 4.3.
So I'm having issues.
As of right now I don't really know what the problem is.
My phone will not connect to my PC anymore. It doesn't say "Connected as a media device" or anything.
I can't connect it to my PC with Odin in download mode either
My phone will not charge anymore (Using Ampere, it charges at about 220mA. It'll go all the way down to 10mA and for 4 seconds or so it'll be at a high mA like 470mA)
It is not my charging brick (I've used Three and I tested them on my other phones, the bricks work fine)
It is not my charging cable (I've used several, and again, I've tested with my other devices and it works flawlessly)
It is not my battery, I have 4 and I've switched between them all
It isn't my PC (I reinstalled all the drivers, and it worked with my Note 3 immediately)
I've tried pushing the cable down while plugged in, and up. It doesn't do anything.
My ROM that I'm running: Maximum OvrDriVE, it is a Note 5 port. Android 5.1.1, with xposed.
My kernel is Emotion r23. I'm on DOK2 baseband.
I've reflashed this ROM, and PacRom. Same issues.
I've flashed different kernels. Same issue.
Right now I'm going to try to go back to a different ROM that I was using that I know for a fact works fine.
(Tried it, it was Rapture 8.1, android 5.1.1, kernel: Emotion Kernel 5.1.1 r21. Nothing changed. Fast charging enabled, still said was being charged via USB when it was plugged into the wall. )
A physical inspection of my USB port on my phone, it looks fine.
I cleaned it too. Still, same issues.
So this only leads me to believe its a physical problem.
Can any of you guys help me out? Because I'm still not sure exactly what the problem is, and I need help
Its your phone, I had the same issue. Warrantied it through tmobile. Exact same problem. It is frustrating for sure.

Damn. Well, i thought so. I'm just going to replace the Micro-USB port then. That's less than $50 vs a new phone which is about $230
I don't have warranty. I bought it off amazon and it's been perfect up until now. I'm sure I caused the problem and 'll be careful not to do it again.
The scary thing is that I'm not 100% sure that it's the MicroUSB port. It can't really be anything else but I just don't want to buy this and then it turn out to be something else. I guess I'll have to try though.
So, update: Replaced USB Port.
Broke LCD Screen.
*sobbing in a corner*
Oh and it appears as if my USB Port doesn't work still (Same issue. It does work to a point but as of fast charging I dont know but when I turn it on and unlock it my comptuer doesnt recognize it)
