[Q] Stuck in bootloop, can't flash using LG flashtools...help? - LG Optimus G Pro

So, i scoured the forums, searched for my error code and nothing...
I have a new E980 that I rooted, installed CWM on and left the stock ROM. Earlier today, I get a notification for an OTA update.
I figured I didn't desperately need root, so I unrooted through SuperSU, and said to hell with it, and accepted the update.
Phone reboots into CWM and is now only booting into it over and over.
I looked up how to recover from it, and I've been trying to flash it using LG Flashtool ver 1.5 and everything goes fine until I actually plug the phone in with download mode on and LG FT in the "Ready!" state. LG FT then starts to flash it, goes to 3%, immediately to 100% and then fails after 5 seconds. Error code F0000002. I tried everything over and over again and I get nothing.
I have my COM port set to 41 and LG Flashtool set up properly according to the tutorials.
Any ideas?

I had to use the LG R&D test tool to flash the panama rom then root & install CWM. With freegee and then restore my stock.E980 AT&T backup. Kept getting a "Previous loadfailed" error with LG flash tool.

After using Freegee to unlock my phone I am now stuck in CWM bootloop

I have done this before but I used what seems to be a different version of freegee (didn't have the option to backup efs or flash TWRP) so I unlocked my device and after it had completed I rebooted and then powered down. I put my phone in to CWM and flashed the stock debloated ROM. After flashing this ROM I was stuck in a bootloop. I ended up using LG Tool to get it back to stock. I thought it must have been a random once off issue so I tried again with Freegee, same thing happened, only this time no matter what I do I can not get LG Tool to fix the issue as it keeps giving me the error of low battery even though it is at full capacity. I then tried to use BC2 to flash a kdz file and I get the same error. I have since tried factory resetting, sideloading different recoveries, ROMs and basebands without boot. I have tried to use LG Tool about 50 times and it is not working. I have changed USB ports, reinstalled drivers etc, just keeps giving me that error. Yes I have set permission in the app and I am using Windows 7
HERE IS THE WAY TO BYPASS THE ERROR MESSAGE

Sprint LG LS980 (OptimusG2) stuck in download mode or stock recovery

Hi all. I'm not a novice when it comes to rooting and flashing but I'm stuck on this one. A friend of mine tried to install CM11 on this phone, the LS980 and somehow really jacked it up. It's stuck in a bootloop, but I can get into download mode and stock recovery. All data has been wiped. I have tried using the LGFlash tool to install the stock tot and dll but it fails. It fails because the the tool says the file is the wrong model for the phone. Here's the thing, its not. But somehow the phone now thinks its a D802 instead of an LS980. (This happened during the CM11 attempt somehow) The flash tool fails every time. I even tried the D802 files and it started to flash but failed about a 1/4 of the way through. That confirms that the phone definitely thinks its a D802, weird. When I hook it up to the LG Support tool, it tells me the phone is a testmodel!
Needless to day I've tried everything I know how. ADB sideloads, different recoveries, and I've researched for hours on end. I have hope that there's still a solution. I would be golden if I could get a recovery on it, either TWRP or CWM. Any help is appreciated.
have the same problem. simply cant recover the recovery.
My recovery for e988 g pro in lg g2. I try everything for fix the recovery but cant help it. Is there any way to re build recovery?

[SOLVED] G3 boot looping after running a repair (out of options)

Hey there all.
I was going to upgrade to the OTA Lollipop update to give it a test but something went wrong.
I'm running a Vodafone Australia model D855 (v10e if I recall).
Firstly I downloaded and started the install of the OTA update. Upon restarting, the phone would boot into TWRP instantly. No big deal. Decided to flash CloudyG3 instead of stock as I couldn't be bothered trying to fix the OTA update. So I did a full wipe, flashed the baseband and then flashed the ROM. Reboot and it's still going straight to TWRP. So I ran the fix for it that clears the FOTA and Misc folders but even that didn't fix it.
At this stage I decided to use PC Suite to try repairing the phone back to KitKat and start again. Upon running a repair the phone would start some sort of flashing even though PC Suite wasn't detecting anything. Now it won't even boot to recovery, just keeps looping the LG logo.
I've tried installing a .TOT fix (using the European v10e .TOT dated July 8th 2014 AND the Hong Kong v10b .TOT dated July 1st 2014) but that fails showing DOWNLOAD FAIL (Model is different, check phone model or DLL). I'm also using the LGD855_20140526_LGFLASHv160 DLL file.
The other thing I tried was a .kdz fix but it kept showing an error "No connection to server" and clicking ok would close it. The phone would then get stuck at 18% flashing.
Any help here would be appreciated. I'm currently at a loss as to how to fix this.
SOLVED: I tried the .kdz fix again but instead of clicking "OK" when the "No connection to server" message came up I just let it go. I checked the background window and the flash was still going through. I watched the phone and it went through all the way eventually. A few reboots later it's back to the home screen and I'm ready to properly flash a Lollipop ROM.

Bootloop or something else?

So I rooted my phone by installing the rooted 13b img. And went to install xposed framework and apk. I completed all the steps found here (http://forum.xda-developers.com/g4/themes-apps/guide-installing-xposed-locked-t3181593), and now it is stuck on the android logo....suggestions on what do do from here?
A little more detail: After completing steps verbatim, it would fail to install framework. I then read somewhere else that you need to uncheck not only auto mount but the mount option, as well. I tried that and it seemed like it must have worked as it didn't immediately fail and reboot. However, it got stuck on the android logo and after an hour or so I realized there was problem. I have pulled the battery and rebooted several times. I can boot into download mode, but cannot get it to fully boot. Since I could get it into DL mode, I used LGUP to install the 24C MM update (as I didn't have the 13B on my computer). But the result is the same...stuck on the Verizon logo even after a successful install of 24C.
Is this a case of the hardware failure that others are experiencing or is this software related? I see a lot of people with bootloop issues and mine seems to be similar but different. Mine does get past the LG screen to the next screen, but even installing a stock kdz doesn't seem to help...
UPDATE:
Well I downloaded the stock 13B kdz and flashed it via LGUP and it somehow managed to boot. It looked like it was going to be stuck on the Verizon landing page but after about 10 seconds or so it completed boot up. I have now installed the rooted 13B image and made a backup img. I might try again to install xposed framework - fingers crossed it doesn't screw up this time...
Use hyleton's 'LG G4 Stock Firmware (Go Back to Stock) KDZ & TOT Method' that uses LGFlashTool2014.exe and do a CSE Flash - this will wipe all your data though

Click to expand...
Click to collapse
Thanks, I'll look into that. I was hoping that using LGUP to reflash to stock would do it...but I guess I have to remove whatever the flash tool put on my phone when trying to install the xposed framework...

HELP! Fully wiped. Only Recovery mode is possible. Help me flash a stable ROM.

What I've done:
1. Tried LGNPST method but phone never showed up in the software
2. Tried flashing with LG official tool. That always resulted phone disconnected.[I did put my phone into download mode]
3.Tried almost all KDZ_FW_UPDATE methods they always stopped either in not responding-> close program OR extraction error
4. Tried sideloading using adb but they also resulted in "bad file" even push didn't work saying no permission to write(I think)
for adb I tried converted .zip of kdz using some guide in xda.
My phone is totally clean now. I can boot to Recovery or Download Mode. There's no file that's flashable right now. I'm in Philz touch recovery
This actually happened while I was flashing to unlock bootloader and charge went low.
I desperately want it to function properly. Please anyone with any new or updated methods, help me.
When normally trying to boot up, Google logo comes and phone switches off.
I was in F180L converted to E975.
I've INDIAN(20a) version kdz also european(10h) and korean(30e).
