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?

Hard bricked VS985 after ROM flash failure

Sorry, I'm relatively new to rooting and I looked through the threads and found similar problems, but none that seem to exactly match mine.
I have a rooted VS985 that I was trying to flash with the AndroidNow HD 6.1 ROM using TWRP and I guess the flash tool crashed. It was stuck on a black screen for an hour or two so I hard reset it and after that, the phone will only flash the LG logo for a second before the screen turns off and the indicator light alternates flashing red and blue. As far as I can tell, the computer does not detect it when it is in this mode (seems similar to the secure boot issue that some people have been having). I cannot enter download mode (the LG logo flashes on and the indicator light flashes blue once and then both turn off) but I can still boot into TWRP Recovery. When I try to boot into download mode, even while the screen is off, my computer detects the phone as QHSUSB_BULK. Also, when in recovery mode, my computer can detect the phone as a G3 and I can access it with adb tools but I don't know where to go from here. I have tried using the LGFlashTool but I can't seem to access the phone because it will not enter download mode and I've tried reflashing AndroidNow HW 6.1. The flash completes and says it is successful, but the phone still will not boot properly.
Luckily, I got the phone a few days ago from Costco, so there is a good chance I can still return it, but I would like to fix it if I can.
Any help would be greatly appreciated.

You said you have adb working.
Did you make a backup of your stock download mode at anypoint of time? (Iaf.img)
I guess it can be pushed back using adb, but am not very sure. Even if not, maybe you can take the stock Iaf.img from someone else and try pushing it via adb using this command:
Code:
dd if=/storage/external_SD/stock-laf.img of=/dev/block/platform/msm_sdcc.1/by-name/laf
Then you can boot into the download mode using the command:
Code:
fastboot boot stock-laf.img

It doesn't look like I have the stock laf.img backed up. I'll try to get it from someone. Thanks, I'll let you know what happens when I get it.

[Q] Help Unrooting!

Please don't refer me to any more threads or forums........
I'm sure this has been done and done and talked about but I've been reading the **** out of forums and comments for a few hours now and trying to unroot my Sprint LG G2.
I had it running stock like a champ. rooted it. worked great. then I was attempting to flash lollipop and it required a recovery update (No Problem) I downloaded the correct files and bam! it says your phone is not rooted this requires a root (or something like that) I was already rooted SuperSU installed and root checker said I was fine. so what the hell I swipe to root while inside recovery and it goes to some black screen with tiny text saying fastboot: processing commands and won't leave the screen. I tried booting into recovery and same thing happens. Tried to reboot normal and I'm stuck on the LG logo with my led flashing between blue and green slowly. I CAN boot into download mode and I'm following this

Please help!
When i'm in download mode the phone does say I am rooted. is there a way to just re-flash recovery and restore from my backups I did before all this? if I have to wipe this thing clean and start over I don't really mind I just need to get my phone back haha this is the first time this has ever happened to me and I consider myself tech savvy so idk what I did here (except re rooting in recovery like an idiot) thanks so much!

First question, is the download mode you see with a small status bar or the big one?
If you have the big one, download mode should work. The f flash software will verify the tot file. If that goes through you should be golden.
When it asked you in TWRP to root, that is a message telling you system or ROM file did not take.
If you want cm12, use zv8 tot. Root, auto-rec, update TWRP with blastgator bumped TWRP 2.5.1. Flash cm ROM or aosp, then gapps. And go

D850 Hard brick after TWRP and Security Error

Sorry for any mistakes I may make in this post, it is my first time posting on XDA and any constructive criticism is welcome. I recently rooted my D850 G3 and it worked beautifully. After doing this I decided to take it a step further and flash TWRP as a custom recovery. I was very careful to flash it for the D850 and make sure it was compatible with my software version. After a successful flash I made a full Nandroid backup before rebooting. Upon rebooting my G3 showed the LG logo and underneath said, Security Error, with no additional information. It repeated this after I had removed the battery and then went dark. After this point, my phone was not even registered on my PC COM ports and is truly a brick. If anyone has advice for this situation it would be greatly appreciated. List of things I have already tried: Fastboot, Traditional unbrick, Traditional unroot, Boot to recovery, Boot to download mode, Charging phone. None of these have worked so far.

Have you tried this?

BTW to unlock the bootloader with bump, you need to be on kitkat (It won't work on lollipop)

Bricked LG Gpad 7.0 V410

Hello all, I just purchased a new LG V410 and decided to root it using TWRP with flashify. I've done this before with other phones with much success and followed the instructions precisely. I was able to root the tablet successfully, but when using the flashify install the TWRP custom recovery the phone rebooted into fastboot.udc and I have been stuck ever since. I can no longer go into download mode or recovery mode and when I try it comes back to the black fastboot screen with errors. I have to do a hard reset using Power and vol down just to restart the tablet, which otherwise works fine and is detected by my pc and the minimal adb fastboot command interface. However, the mobile support tool doesn't see the phone and I have downloaded drivers several times with no change in status. Please advise as I think that I may have fully bricked my tablet. Any help is appreciated.

Hold the volume up and plug in the usb to get to download mode properly, as well this http://forum.xda-developers.com/g-pad-10/general/kdz-lg-g-pad-7-0-v410-t3224867. Unbricked mine with that method. Hope that helps!

Just to let you know why it bricked and you often can't just use Flashify or anything else to merely flash TWRP anymore, its because of the locked bootloader. On other LG devices such as the VS985 G3 and the VK810 G Pad 8.3, we have to use old KitKat bootloaders (from the same device) to be able to get into TWRP. At least on the VS985, the KitKat bootloader was still locked, but it was vulnerable to a method to get around it called "BUMP", so anything that boots - kernels, TWRP etc, has to be BUMP'd in order to work, but still requires the BUMP-vulnerable bootloader.
