Hello i have recently updated my ROM but sadly something happened with my service, it just said "no service" and i wasn't able to receive or take any calls so i installed this rom again from the recovery, and then when i rebooted this device, it suddenly stopped on the green goblin logo loading screen and my device was unrecognized by a PC, recovery didn't work... so i tried a RoFUSiON which can install a rom through the pc but my device, as i said, wasn't and isn't recognized anymore. What i can do? i can't even charge it, last night i connected it to the charger and let it on. When i woke up and unplugged it, it had no battery! probably it wasn't chargning, it was discharging, and the only way i can turn my mobile on, is plugging it to the usb, doesn't matter if into the power socket or usb-to-usb, even the screen lights up without the battery but still i can't go to the recovery or fastboot (probably, because as i said my device isn't recognized so either that's the problem either fastboot doesn't work). Here's also the video about this, maybe someone can help me since i don't know what to do.. thanks in advance.

Hello. I'm new to the forum, and the issue that brought me here as had me fulling my hair out of the last three days.
I'll try my best to make this short as possible. I have (obviously) AT&T Lg Optimus G (E970) that was running 4.0.4. i rooted and unlocked it and flashed a cm 10.1 using TWRP. Yesterday tried to flash a zip for a transparent status bar mod. But the flash resulted in CM getting stuck on the splash screen. So i booted in TWRP recovery mode to restore from a recent backup. In the midst of wiping my rom and going to restore, i guess my phone died (which was weird because it had a substantial charge). Then it would no longer power on, and the only was i could get ANY response was by plugging it on the charger. All i get it the red indicator light. my phone will only turn on when plugged into the computer. from there the only two thing i can do is enter download mode and boot. and when i try to boot, i will get the lg logo for a moment and the the screen cuts out and goes back the the flashing red light.
so I trien the LGNPST method.
i downloaded the auto LGNPST and installed just fine. downloaded teenybin and lg stock bin. i've tried to flash both (put phone into download mode, select the dll and select the bin file). what happens is everything starts off fine, then when it gets to 67% the phone reboots, then goes back to the flashing red indicator light, and a message on LGNPST will pop up saying the phone has been disconnected, and to reconnect to continue. so i'll unplug the phone, plug it back in, and put it in download mode, and hit continue. LGNPST will say complete but the phone will still be just sitting in download mode. and if i unplug it, it's goes back to square one (red flashing indicator light)
EDIT: i was flashing the v11c stock bin. i just flashed the v20j bin and now we're boot looping while plugged in (lg logo for about 2 seconds, shut off, repeat) progress???
SO SO SORRY FOR THE LONG READ. Just trying to give as much info as possible hoping it helps.
My question is, is this a hard or a soft brick, and do i have any options left? after researching on here i'm hoping JTAG isn't my only option (I don't have the time or funds to go that route) and i saw someone mention taking it back to at&t, butIi don't think that would help me any since rooting the phone voids the warranty, correct?
I'd be eternally grateful for ANY advice. i'm at my wits end, and i've been google researching this for so long i'm starting not to even comprehend what i'm reading. PLEASE HELP!! And thank you so much in advance.

If it is hard bricked when connected to computer it will show up in device manager as QDUSB Device or something similar. You could try to do a factory reset with button combo, be sure phone is powered off then hold power and volume down until menu shows up.
You Can Also Try TeenyBin If Factory Reset Does Not Work

thanks for the reply guys. it looks like my phone is showing up in the device manager under ports as "LGE AndroidNet USB Serial Port (COM3)" is that a good sign? i'm going to try flashing teenybin again.

Yes, you are not dead in the water. Proceed, young grasshopper.

All the custom, unofficial 4.2.2 roms I found on XDA require that you be on the latest LG 4.1.2 OTA.
There are also links to stock rom and kernel so you don't have to mess with LGPT whatever. No need to do OTA etc, if you flash this.
http://forum.xda-developers.com/showthread.php?t=2219953
I also found TWRP to be far easier to install, which is installed by default I think with FreeGee. But you can find thread for the latest TWRP 2.6. TWRP makes flashing and wiping cache/dalvik super easy.
Ok, so i'm starting to think this is a battery issue as opposed to a hardware issue. i could still be wrong. I've flashed the stcok rom after stock rom. When i plug my phone into a computer usb port it LG logo boot loops (and this is the only way i can get to download mode), but when i plug it into the usb wall charger, i just get the red flashing light and no other response. when it's not plugged in i get nothing.It's still showing up as "LGE AndroidNet USB Serial Port" in my device manager and i can still get to dpownload mode just fine, so i know all isn't "according to what i've read and been told". So i'm running out of fixes. I did come accross a thread on here suggesting i unplug the battery and plug it back up. So i'll be getting the tools and praying that works.
I did also come across an interesting thread on another forum. They were saying how id you allowed your battery to drain all the way to true zero (which i think might be possible because my phone died in recovery mode), it wouldn't have enough juice to initiate and monitor the charging process. If this is the case, can the batter be brought back to life? a jump start or something (lol)? or will i have to just replace the battery?
THANK YOU SO MUCH FOR THE HELP SO FAR GUYS.
When you used lgnpst to go to 11c it boot looped because you tried to go backwards from cm. If you did a factory reset afterwards with button combo it should boot. Also can you get into recovery after flashing teenybin to do a reset and flash a ROM?

i did a factory reset a few times, but it still never booted. and whenever i LGNPST, when it hits 67% the phone reboots and just starts bootlooping (if i flash a stock rom) if i LGNPST teenybin, at 67% the phone will shut off and the flashing red light will just come up. and after each a message will say phone was unplugged or lost connection. after both instances ill plug it back up and put it in download mode again to finish and it will complete, but the phone will just be sitting there in download mode. and if i reboot.... bootloop city.
i cam across this thread that seems to detail my issue perfectly. so i'm going to attempt a teenybin flash one more time to tryt to get recovery mode (havent been able to get it at all), and if that doesn't work i'm going to do a battery pull..

BATTERY UNPLUG WORK LIKE A CHARM. again, i followed the method [r.]GimP laid out here http://forum.xda-developers.com/showthread.php?p=43732147#post43732147
i was nervous because i've never opened my (or any other) phone before.
and thanks to the tot link provided by zymphad above, i'm now running jb 4.1.2
THANK YOU GUYS :highfive:
I found LG's camera lacking, but 4.2 has an update for that, plus the camera mod, much improved I think.
Running RootBox great now with 124mhz idle, GPU downclocked to 200 and CPU undervolted to 85, stable and cool. I don't 3d game on phones.
Glad you fixed it, I just hope someone makes a high capacity internal battery for us since taking it apart isn't that difficult.

Hi,
I've got Lenovo s650, rooted with a custom rom (MIUI). All was perfect for weeks but few days ago it started randomly going off. Then I noticed that sometimes when I listen to music it crashes (making the music freeze and repeat same note for like 10secs) and shuts down. I thought it could be related to some apps but since I was very busy I didn't do anything about it.
Now today I noticed that my phone suddenly lost network coverage (in area where I always use it). I tried airplane mode on/off but didn't help, so I powered off and thought I will do hard reset when I get back home. However since then the phone is completely dead. Can't get into recovery, if I plug into USB nothing happens, if I take out the battery the red light turns and it goes to "META" mode for few secs (as it's intended to) but I can't download anything into it as I get some DRAM error in Upgrade /flash/ tool.
Funny thing that somehow I was trying all the combinations Volume up/down/both + power and at some point I randomly managed to turn it on so I was gonna make a backup of my stuff but it froze and shut down again. Now nothing works......
Any ideas what happened? :/
Some additional info:
I've got TWRP recovery (however I am unable to re-download it again via flashtool because of DRAM error).
I tried getting into adb but I am not sure if it's possible when the phone is off (tried volume button combinations with battery in and out but nothing).
Also when my phone is with battery and I put it into USB, pc recognizes it as "MTK USB Port", but it keeps disconnecting and reconnecting every 5 seconds. Tried to replace it with adb USB driver but didn't work.
Not having a phone I'll probably give a "Format all" option a shot in flash tool... either gonna brick it forever or fix it..
Edit1: Can't even format due to DRAM error....... :/
Edit2: This is so bizarre... I managed to connect my phone a couple of times in Mediatek preloader mode so the flash tool started flashing the rom, but stopped in a few mins unable to format something because it's protected.
I also managed to turn on the phone a couple of times and tried connecting via adb, but once I grant root permissions, adb shell on my pc cannot find device anymore.
It seems like either a hardware or kernel problem but I know nothing about either of them..
Edit3: I don't know how but I fixed it. Phone seems to be fine for now
Edit4: After 1 hour of working the phone died in exactly the same way.... And so this 6-week old phone will be going to rubbish bin. End of my blog.
Hello Yesterday i have upgraded my phone ROM.
First have unlocked the bootloader.
Next, followed this video to upgrade to Android 5.0 AOPS build:30-11-2014 by Artas.
It was great and useable while i did not installed a new CWM.. (CWM 6.0.4.5 Touch by Pollos).. after that, the phone is stucked at "LG" logo and while i charge random times reboot..
Earsed all with fastboot, and now the phone is not turn on while i charge or try to turn it on..
I have got this problem earlier with an other android version (sercurity error) and the S/W update was good.

Hello
is there any chance a kind person can help me with this dead stick?
a few information about this phone:
- as far as i was told, the phone died after an update
- when i plug the phone to the charger nothing appears on screen
- when i power the phone nothing happens
- when i volume up + power the phone nothing happen, same with volume down + power and volume up+down+power
i have installed the lg tools and using the imei downloaded a 600+MB package which should be the restore image of the phone but when the procedure starts to flash the image it gets stuck at 4% trying to connect to phone without any luck
if anyone has some ideas to give i would be very happy to try them!

Now.:
When i try do S/W upgrade with the "LG Mobile Support Tool", it stops at 4% and the phone disconnect itself from the PC.. the installer goes (without the phone plugged in) 4--->8% and if i turn again my phone to download mode, go to 15%.
At 15% again disconnect and the installer say "Error, try to unplug USB and remove battery and try again......"
I have tryed KDZ offline flashing but it is force quit when i click "Start"..
Tryed:
Official support tool - Say "You have already installed the latest version (V20H). If i try to "Upgrade errors fix", it stop at 15% as i said..
Fastboot - earse boot, system etc.. after that again upgrade, but stop at 15% and phone turn off.
LG Flash tool - these 90% exit with some error before i can start anything..
I hope you can help and understand my bad english:'D
Did you invoke "Download Mode"? If i remember, this requires switching the phone off, and attaching it to usb while keeping volume up or down pressed, and will show a special screen, if successful.
Download mode is even more basic than fastboot or adb, and the final line of defense, before throwing the phone away.
All LG tools require the LG usb drivers. These at least no longer recognize the phone with Artas' CM11, except for when in download mode. Then Windows should auto-install a virtual COM port. For ADB and Fastboot you need different drivers then, like those from the Google SDK. But with these the LG tools won't work, not even the sync suite.
can anyone help with unbricking lg-t385? friend gave me the phone saying it just turned itself off and after that it doesnt work (as always, nobody touched anything :/ )
when turned on it hangs at LG logo, if i remove the battery and connect it to pc the same happens although by the plugged in sound on the pc you can tell that the phone is connected, it even shows up in device manager. if you remove the battery and plug in a wall ac charger the same happens, phone turns on and hangs at the logo. tried pressing all the combination of keys to get to recovery or hard reset. nothing works.
flashing, rooting, unbricking etc is not new to me, but this is my first lg and first non android phone for that matter.
tried flashing with LG Mobile Support Tool without luck cause it doesnt recognize the phone.
can someone please help, or just point me in the right direction as to how to reset it to factory or flash stock?
thanks in advance
nobody?
