I was working away on my computer with my X1 plugged into my monitor which is plugged into a little USB hub which is plugged into my PC. I have a bunch of devices plugged in, including my internets wireless.
Suddenly, all the USB devices lost connection and my phone screen went blank.
In a minute, all the other devices, including my wireless internet. But I couldn't get my cell to turn back on.
I tried plugging it back onto the USB connected to the monitor, and then into a wall-plugged USB - and I only got flashing red lights.
Can this be fixed?

Hey -
Yeah, I checked them, but none of the ones I saw seemed to apply to a completely full battery.
Anyway, thanks. I had another battery - (I've had two X1's having dropped one) - and I put it in and it works fine.
Cheers.
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
I changed now the micro USB but still the phone won't turn on!
I put it to charge but the red light keeps turning on and off.
on and off
on and off
What does this mean?
Is the battery dead?
Is the usb connector damaged?
Is the board damaged?

I have a malfunctioning usb port and I want to change it. In Lebanon we don't have paypal (Don't know why )
And I dont think we have an HTC center that sells the required part.
So tomorrow I will go treasure hunting for broken htc phones in phone shops to find the usb port.
What other devices have the same port?

Did you fix it? My led flashes when I try to charge from completely flat battery. I just leave it on charge for a while and eventually the led stays lit and I can switch the phone on.
Other than that, are you sure the port is connected correctly?
Well this problem drives me crazy.
My phone (i9070) doesn't make any sound when I plug it on my computer or charger and no charging indication appears either on the phone.
On computer side device appears under the storage devices.
However is seems that the power connection is working since if I restart the phone while the power plug is still connected the charging indicator appears. In addition after the restart the battery seems to reach 100% extremely soon (which is not normal at all). Unplugging the charger (or the computer) doesnt detected either by phone, the charging indicator is still active until restart.
I tried to factory reset the device and still "no juice".
I have tried 3 different cables with two computers where the device was connected few days ago without any problem.
I don't know what should I suspect.
Faulty battery? Faulty data connection on phone plug? OS based issue?
Any ideas?

What ROM and what kernel you are using?
Sent from my GT-I9070 using Tapatalk
Sorry forgot to mention these info:
Kernel
3.0.31-CoCore-EP-8.2
Updated to 8.2 after the problems I had CoCore 8.0 until the problem appeared.
ROM
LightJB v1.2
I used to work with JellyMod v4.0 until the problem appeared and I switched to LIghtJB v1.2 to test if the problem fixed but the same behavior here.
Should I replace my battery?
Is there any way to check if the USB connection gets detected by the phone hardware (a diagnostic procedure)?

Put the phone in download mode, connect to PC via USB cable and open Odin. If the phone connects, I recommend a reflash with one firmware.

Is it charging? Bad cable? Change USB port on PC, put it in some other.
You said you have charging problems? It is not shown (in phone, procentage is not going up) or it is not charging at all?
Luckily for u it's a broken flex (cheap) it costs $10 including tools to fix it yourself on ebay

Many thanks, that's interesting, but I would like to preserve my data, and that procedure will wipe all data on the smartphone. I dint't try to enter in download mode, though I can't see any device in the windows device manager.
Today I replaced internal battery with a brand new one with no results. Trying to charge, both the charger and the phone remains cold, so it seems no charging process starts. Now I will leave the phone connected to the charger over 24 hours, as some users suggest. The phone was very warm when bricked, and it was connected to the wall charger - maybe some kind of thermal protection occurred. If it won't resurrect tomorrow, after some more software tries, I will order the flex cable with usb connector. Little chance, but one more try.
I will let you know.
Thanks

Hello,
I fixed the problem: it was an hardware issue. I replaced the charging circuit (that includes the type-c connector) and the smartphone immediately woke up. All my data were preserved.
