Well it's been a while since I broke a phone, so here I am!.... again

LS980. TWRP Rooted. Failed CM. Now stuck in boot loop.
I'm running Windows 7 64bit. I have latest LG drivers. Phone can boot into recovery but nothing else. I cannot boot into LG's "Download Mode". I can get into the "Hard Recovery Mode" which doesn't work anyway (Vol Up + Power). From recovery I can select to wipe cash and data and I can select to install from sdcard (no cards on this thing) or from ADB. When selecting ADB and trying to sideload stuff to it, it tries to load but always fails. If I try to push stuff it always comes back :closed

I cannot access any form of Fastboot. All i can do is let is loop or enter recovery. Since it seems to be the only thing I can access, can someone please assist me in what I should be trying to sideload that might get me a step further? I cannot fastboot so anything there isn't an option. Seemingly all I can try to do is sideload something. What... I'm not really sure. And no I don't have a backup.

Please help!

I am on verizon. Had this happen to me once. Are you SURE you are hitting the buttons at the right time for download? I have never heard of this failing..on any phone. I would almost bet it's accessible and you aren't hitting it in time..maybe? Good luck!

do you have the LG mobile support tool? If so we can use it to get past this, I did it once recently on my G2. If you still need assistance just say so..

Hey so when you try adb sideload it starts up then fails? Have you tried just pushing to recovery with adb also? Universal drivers? Sorry for all the questions just trying to help

You were right, I was doing it wrong. Once I got into download mode it went easy.

Response to others, I found that if I held vol down by itself long enough, the phone would stop bootlooping and shut off. I could then properly go into download mode.

Thanks for the help

I failed to mention it boots to FTM Mode, shuts down, reboots....repeatedly

1. Hold the power button until the device is OFF.
2. Download LG drivers to the PC (LG VZW_United_WHQL_v2.11.1) and LG mobile support tool (B2CAppSetup).
3. Install these packages.
4. Plug in you USB cable into the phone but not the computer.
5. Hold volume up and insert the USB cable to the PC- the phone should boot to 'download mode'.
6. Open the support tool and click Options>Upgrade Recovery, follow the prompts.
7. At the first prompt indentify your phone using IMEI/ESN, then click OK
8. Let it do its thing, the phone will reboot and most likely have a bunch of error messages and some FC's. Just hit okay to all messages, the phone will settle after 2 minutes or so.
9. Download freegee from market and reflash recovery of your choice.
10. Make sure you have a ROM saved to the SD to flash
11. Use freegee to reboot to recovery
12. Once in recovery you can reflash the ROM as normal.
13. Reboot and Profit!
*$* Or you could go back to Stock and start fresh!
*$* BEFORE ANY FLASH ALWAYS STOP and MAKE A NANDROID BACKUP!

Good Luck and if you get stuck let me know

Similar issue
I'm stuck in bootloop, no custom recovery or root. All data has been deleted. I have tried the LG support tool, but it locks up. It also tells me my device is a test model, something bad has happened. I can get into download mode but can't flash stock, via the flash tool. It says wrong device, and at the download screen where my phone says rooted it says the model is a D802! Somehow this info got jacked up! I can almost make it through the D802 flash but it fails also. I only did that to confirm my suspicion that the phone thinks its a different model. I'm open to anything, I've tried it all.
