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 guys,
My XT910 ran Cyanogenmod 11, Kitkat Nightly. Tonight an OTA update appeared (something called snapshot or something). Thought it might fix some thing that were not quite right in my version so decided to update. At some point during this process the screen went black then the M logo appeared than the android recovery menu (i can load it). And nothing else. I tried rebooting, wiping cache, reset to factory, nothing works. Copied several ROM on the sd card because i have the option to update from sd. Nada. I gotta tell you i'm on a Mac and i cant change that this week, no Windows till next week. And probably the battery is draining...
What to do?
This is how it goes:
I can not power down the device
It restarts periodically if no action taken
at first the M logo appears
instead of CM logo there is a robot with an exclamation mark inside a red triangle
i can get into recovery menu by pressing the volume keys
i can choose one of the options but nothing else
when applying updates from sd card (stock 4.1.2, nightly rom or snapshot rom) it goes up to "verifying update" then it abandons
Later edit:if i reboot from recovery menu and when it powers off i press pwr and vol- it goes to boot menu. No windows means no adb hence power off from that menu. when i plug in the charger, the M logo appears andstays there. Question: if it does actually charge the battery and i dont fix it before getting a windows, what kind of rom should i flash? Stock?
OK, I tried updating the M10 snapshot today over my current M9 snapshot that I had installed.
As it was updating, the screen went off and then I couldn't get anywhere past the M Logo, pressing the volume keys I'm also able to navigate to recovery etc.. but that's it.
I was not able to boot the phone off and even though the screen was off, I don't believe the phone was off. When I got home, the only thing I knew to do was to flash a stock JB rom using RSD Lite. But when I tried flashing it a few moments ago, it failed - the battery is low apparently. Putting it on charge I can now see a charging logo on the screen that is not centered, but I believe it is charging. Once I've got some juice I will try flashing it again, and then I think it's a whole process of rooting it, installing SafeStrap again, and then starting over with CM11.
I don't know if you can even get RSD Lite for MAC, but it's the only way I know that should work to get the phone back up and running.
Thanks for sharing.
There is no RSD for Mac, nor something similar. But i've managed to set up a virtual xp machine (modern.ie), installed everything, captured the usb port with the phone stating "usb connected". Unfortunately i just couldnt connect the phone to rsd, no matter what i did.
Oh gosh.
I managed to get my phone back by flashing the stock JB rom and then working from there.
Try going to the boot menu thing (hold down all keys) and then navigate to AP fastboot. RSD lite should see the phone in this mode.
But make sure the battery is OK first. I did manage to charge it to 40% and it then flashed after it had some charge. Seemed to flash it a little differently than other times. Also the phone said "Device is LOCKED", but thankfully it all worked out fine. Now I'm on CM11 09/15 Nightly.
Have you installed the Motorola drivers?
Maybe you can't do it through a VM.

"Device is locked" means that bootloader is locked in our phones,except those few developer edition models.

I'm glad you could do it. Mine seems to charge as well, it's now close to 24h since it bricked and i assume it would just die if it wouldnt charge in that particular state. Fortunately the keys on the Mac keyboard started working again after drinking beer two nights ago so i dont need to trick the virtual machine anymore, but unfortunately i just cannot get the rsd to see the phone on this VM. Probably should try a VM with windows 7 - i guess ill just do that. I have installed the drivers, the VM recognizes the phone (moto spyder adb...) but rsd wont see it, nor the adb driver installer (it needs to identify the device in order to install the proper drivers). I know that rsd is picky when it comes to usb cables, it might just not work with the original cable, but after trying 4 different cables i tend to think this is not the problem
P.S. I'm very upset on Google about killing Motorola and being disrespectful with its own customers (i mean i would have been expecting to be the first to get Android updates, not to wait one year to be able to update from 2.3 and i couldnt imagine they will not roll out RAZR updates after 4.1.2) so my next phone will be a Nokia Lumia. The coolest one, like my StarTac, my V70, my V3, my RAZR...
You maybe successful with a Windows machine
Indeed i was. It was fast and sound, no problems at all flashing stock rom. Though the phone didn't actually charged when plugged in and displaying the M logo. I had to actually sacrifice a usb cable and charge the battery directly.
I have the same problem - I updated to the last snapshot, and did a wipe in safestrap - and got bricked.
Only difference is I can't flash nothing! and in AP Fastboot mode the computer doesn't recognize anything.
I had my Ellipsis 7 Rooting using Framaroot and it was all going well until an OTA update came across. I knew I might loose root, but in SuperSU I had Survival Mode on, so I wanted to test it and see if it would work, but it ultimately didn't. What ended up happening is that after it had the "Android" logo show up it would go black, but stay backlit, and stay like that until the battery died. I took off the back to disconnect the battery and reconnect it then tried the Volume down + Power combo to reset the memory, but that only reset /data. If anyone knows where I can find a stock ROM, or if anyone has a working one that could create a flahsable .zip would be greatly appreciated.
During normal use the phone just locked up and wouldn't respond so I took out the battery and put it back in expecting for it to just turn back on but it just stayed at the Lg logo and I realized what had happened, (I have had multiple issues with this phone in the past) I just shoved it in my pocket and went on business when I pull it out again and the screen is black I click the power button and it shows (Translated from polish)

Reset phone
I've had this happen once before so I sighed angrily and pressed the button to wipe my phone. Nothing again nothing, again and nothing. The button wouldn't do anything. So I reboot it and this time it just hangs I let it go for 3 days straight on the LG logo. I try various methods to reflash the phone back to a working state none of them work and the last one is what shattered it. This is the link for it: http://forum.xda-developers.com/showthread.php?t=2748384 I try using that tool and it goes to 27 percent and fails so I try again and it the process won't start so I (apparently not learning my lesson about rebooting phones) take the battery out and try to get into s/w mode again. It won't go so I rush to my only computer with fast boot working and I couldn't get anything to flash onto the phone. The partitions are missing apparently. So how do I reset my partition table so I can reflash my phone. Note I did try this method: http://forum.xda-developers.com/showthread.php?t=2546571 but the LG software kept erroring about 25%.
Hi guys. So I have been going through xda and Google for hours and hours trying solutions, to no avail. I almost never post on forums for help because I can usually find the solution. Not this time. This is my last resort next to throwing my phone out a window or praying for death's sweet release.
The facts: I have a rooted Xperia Z3v. I tried to upgrade TWRP in order to follow some directions on upgrading to Nougat. I flashed TWRP from 2.8.X.X to 3.X.X.X. I rebooted and it never made it to the Sony logo. Now, if I plug the phone in to either a wall socket or PC it vibrates, endlessly at three second intervals, each time with red LED. If I try to enter flash mode, then its the same but with a brief green led after the red. I can enter fastboot (the only way to stop it vibrating while plugged in) and my PC sees it, including Flashtool, but since my bootloader is locked permanently, I can't really do much with it.
When plugged into the wall-charger, I noticed that the charger's LED changes from "Active" to "Inactive" with every vibration. I'm pretty sure I'm in a reboot loop. The screen is totally dead and there's no logo, but every three seconds it kills it self and comes back.
I have tried everything I could think of.
What I have:
I have the stock firmware ready to go
I have TWRP backups on SD card and PC
I have Flashtool
I think my drivers are good, but not 100% sure
I can fastboot
I'm at my wit's end and losing hope.
Please, I'm open to any suggestions at all.
