So im not new to this android or rooting thing but two days ago my hero died. It started like this... I was running Fresh 2.0b, but i wanted to wipe everything and completely over so i ran the official sprint RUU and the made a new recovery.... you kno all the steps already, so i rebooted it into recovery and had usb mode on and it was acting buggy.. i would have to sometimes mid usb session turn it off and turn it back on. when i unpugged the usb completely because i was done using it, it lost all power???? When i plug it in to chARGE nothing happens, no orange light, no HTC logo bootscreen, just nothing.. what should i do????? what is wrong???
If the led does not come on when plugged into an ac outlet it could mean a couple of things.
1. You battery is bad.
2. You tried flashing something for gsm phones and deep fried your phone.
Have you tried plugging it into the wall for a while? What were you doing when it messes up?

I've also had my Hero not charge or turn on for a while, it eventually did after I let it alone and tried a new USB charging cord...
After owning my Hero for my 14 months, my Hero suddenly stopped recognizing when it was plugged into my computer through USB. The phone charged but did not give the option of mounting the phone.
I have tried connecting with recovery (both clockwork & Amon- Ra), through stock rom, Cm6 and Cm7. I wiped, flashed, removed the battery, removed the SD card, tried multiple computers and multiple USB cables.
One other symptom I noticed is that the battery started burning down very quickly. I eliminated any app that was causing this by wiping and flashing to stock with no apps, but the battery kept burning down.
I finally gave up and brought the phone back to a Sprint store and got an insurance replacement.
Now I have had my replacement phone for all of 10 days, and the same thing just happened to me again?
Is this a hardware problem and I have such bad luck that it happened to me again? Or is this something I might have messed up and could fix?
You could try a new sd card.
Yea its me again with the
Modified Hero
Is it doing this with all computers you connect into? and have you used the same USB cord each time?
Mine did the same thing after about 10 months. Mine also lost hboot or any ability to get to recovery. It did still charge though. Sprint swapped it out under the insurance plan

I have used multiple computers and multiple USB cables. The Sprint store tested it too and saw the same results.
I just got a new phone under the insurance from Sprint and I want to figure out what could be causing this so it doesn't hurt the new phone.
This might be a little late.
Iw as having the same problem with my Optimus V. When I plugged it into the computer it wasn't reading that it was in a computer,only that it was charging, my computer wasn't event picking up the phones usb connection either. I restored my phone, reinstalled all the LG drivers..still nothing. So I went into my device manager on my computer. Next to one usb port there was a little yellow exclamation point. it said that windows had stopped using that device because there was a problem. So i right clicked, hit disable, right clicked again, hit enable and it worked! Hope this helped.
New member here, so please be kind to me
As of this morning after pulling my LG Rev off my wall charger. I go to plug it into my desktop to move some files and what not only to find the phone is not recognizing that I'm hooked to a computer.
Thinking it was a cable issue I swapped between cables and nothing, rebooted, even did the old-battery pull, and still nothing!
However with each cable it acts as if I'm still plugging it into a wall/car charger. Only shows charging and nothing else, the computer doesn't even make a "USB" connected sound, let alone the computer doesn't even see the phone.
Did you reboot the computer and the phone?

I have, let alone tried it out on several computers at home all with the same outcome.
I didn't install any app, other then did a TiB last night prior to putting it on my wall charger(only way to get a good overnight charge vs USB).
I was planning on trying to install the Revolt ROM today. Come to hook it up to my computer this morning, and now this.
I've been having all sorts of odd issues, like the Verizon OTA update doesn't install. Gets about 30% on the updating/unpacking then pops up a {!} and reboots. So at least once a day my phone will reboot for that.
I currently am rooted BTW and i have tried to un-root and even let the update attempt to go, but no avail.
NOTE: I did notice something else just a few min ago, on the stock LG ROM at least. Normally regardless what source Car/wall/usb was being used to charge the phone, It would show both red/green on the LED while charging/charged. Now its only showing green regardless of it being charged/charging.
I think I may just do an exchange from Amazon wireless. Seeing how its within my 30day window yet to do so.
You did change your connection to mass storage when you connected to your computer?
Sent from my VS910 4G using XDA Premium App
Yeah, played with all the settings and swapping modes.
Just for kicks did a factory reset still nothing.
Curious, is there any way to UN-root w/out the ability to use the USB?
Well I got my new Revo, and it came pre-updated already
And major problems since I've had it, constant reboots, almost always losing connection. WiFi wouldn't stay connected either, even if I'm 5 ft from any router/AP.
And I've tried my best to push back to the pre-update, but no avail!
So I've gotten a hold of Amazon wireless and they are doing an exchange for me, I'm going to jump on board of the HTC TB. Hopefully I'll have a better sailing experience.
BTW, any one want an LG extend battery cheap? lol
usb prob on mine just fixed
omg...I just had a similar problem, except mine popped up on my phone saying that the factory cable is plugged in and can not be used to switch usb modes. I was like...what the frick man...this is the same cable I have always used. I tried alll sorts of crap to no avail. Finally, I reinstalled the lg drivers on my laptop and rebooted both my phone and laptop and voila! It all worked again, using the same factory cable that my phone and laptop just had a so-called problem with. Hope that works for you too...I know how frustrating things can be.
had a very similar issue several days ago. all of a sudden, the phone was no longer recognized. tried everything (different cables, different computers, different operating systems, toggled several different options in settings)......to no avail. had to take it back to best buy....exchanged it for a new revo...everything is good now (including the fact that it was loaded with v4).
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
Hello,
I am getting a big problem with my HTC one here, it won't charge. It's been a problem I had for like two weeks, when I messed up the installation of a kernel. I don't know if it's related or if it's just a coincidence, but it has never happened before.
So here is what happened. I make a backup of my rom ( pranoid 4.6 BETA-2) and then install the kernel. I install it and it fails ( can't boot ) because I messed up the choice of the kernel. So I restore my backup and then boot.
Later that day I put my phone to charge, one my computer, and notice that it doesn't really charge. Like I plug the USB cable in, it charges for a few seconds, like maybe 5 but can be up to 30, it's random) and then just stop charging. And if I plug the USB cable out of my phone and put it again, it will charge again, but if I plug in and out of my comp it won't.
I tried charging it with wall adapter, same deal. But the major thing that make me almost sure that it's not hardware, if I plug it on my comp, even when the phone stops to charge, it will continue to detect and be able to access USB storage.
I wiped and flash everything I could and it stopped, just like that and started working normally again. Happened an other time, during the whole afternoon, and then worked again.
But happened to me yesterday and still haven't been able to charge it.
So I came here for help, hope some of you can help me fix this.
Thanks
if you think that this is not the hardware problem, you can try to flash RUU.
Find RUU for your CID and flash it via fastboot.
I assume, that your PC sees your phone in fastboot, right?
If you will have any questions, PM to me, coz I'm not all the time at Q&A here
