Hi,
I have bricked my LG p970 phone. It does not boot neither does it enter S/W upgrade mode (Up Vol + usb connection).
Below are the things I did which bricked the phone:
1. Flashed the phone using custom recovery, which caused the phone to boot with security error.
2. Flashed using V10 firmware and smartflash tools. Android 2.2.2 was installed on the phone and it worked perfectly.
3. I wanted Android 4.0 so I again flashed the phone with V30 firmware using smartflash tools.
4. "Download Completed" was displayed on the smartflash tool.
5. I disconnected the USB cable and since then the phone does not boot. Does not even enter S/W upgrade mode.
Can anyone help please?

Hey folks,
its bricked due to FOTA (I think it stands for: firmware over the air) update. This means the phone downloads a firmware update without computer connection or further PC-Software. Alas it didn't work.
Situation:
Phone starts, displays LG Logo and after that an 'updating firmware' screen for about 1 sec before rebooting and doing it all over again.
What I tried to solve this:
set up a new Win 7 32 bit machine to try to unbrick it. (drivers didn't work correctly on 64 bit) at least the MCCI driver update didn't)
connected the phone with the PC in Emergency Mode (holding VOL_UP + VOL_DOWN + PWR while USB is connected)
downloaded B2CApp (LGSupport Tool) and installed the device drivers for Emergency mode.
disabled the Android(Modem) dirver
downloaded V10D_00.kdz from LG home page
using the phones IMEI and this link:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI_NUMBER_GOES_HERE
This gave me this link
http://csmgdl.lgmobile.com/swdata/WDLSW/LGE720/ADEUBK/V10d_00/V10D_00.kdz
I'm German so this seems all right, but I'm no expert​
installed msxml
ran KDZ_FW_UPD_EN and tried CDMA in CS_EMERGENCY Mode
A bunch of magic happend until the phone restarts during the process and is right back where we started, if I put it back to Emergency Mode while KDZ_FW_UPD_EN is still running the process finishes, but to no avail.
The log of this try is attached.
Where I am stuck now:
phone:
runs in Emergency Mode
is recognized by KDZ_FW_UPD_EN as well es LG Support Tool
Flashing via KDZ_FW_UPD_EN finishes
Flashing yields no result.
What else did I try
download V10C_00.kdz, as well as V10A_00.kdz from LG site and tried those with same result as with V10D_00.kdz
tried 3GQCT Type instead of CDMA
Wild guesses by me:
I need a different KDZ_FW_UPD_EN version, maybe different dll. I got it from here somewhre in a LG P500 related topic.
I messed up the driver install or need a different driver
LG hates me personally and planted this whole brick specifically to get to me.
The device really is permanently bricked, so I did all I could and there is nothing more to do? That would be sad, I hope I'm wrong here.
Additional Info:
The phone is not rooted and has never before been flashed. It ran with the same stock firmware since it was unwrapped.
The phone was not interrupted by power-loss during FOTA update.
The [read phone information] tool from KDZ_FW_UDP_EN crashes every time, maybe this tells somebody where things go wrong
Any help is appreciated. Ask for more info, if you need it.
Update - What else did I try:
I got the LG Support Tool to flash the Emergency Recovery all by itself runs till 99% --> reboots --> still stuck in same ol' bootloop
reentering Emergency Mode from the bootloop makes the Emergency Recovery finish with 100%, no error, but still bricked.

I can get into cwm but everything i flash just leads me to a screen with the lg logo. Therefore, I'm trying to fast boot my phone and recover my phone but so far I've only been able to get to s/w upgrade mode and recovery stops at 15% because my computer sense that the phone isn't connected. I've tried running the recovery software in diag mode but it couldn't get past 15%. Can someone please help me?

Download LG mobile support (B2CAppSetup.exe) and select recover your phone. Your phone must be in S/W update mode and you must remove/comment LG server line in hosts file (for offline flash)
Try to use Lelus fast boot to flash ICS u-boot & x-loader (according to your phone model). And try to offline flash again. JB firmware does not work with offline flash.
P760 (stock ICS, unrooted, bootloader locked) suddenly died one day, did not react to anything, no recovery mode possible, so can't do upgrade recovery through LG software.
When connecting via USB, it showed the OMAP4430 device. I followed some guides and managed to install the correct drivers and it appears that I can now use fastboot.
Question is, what can I do with it now?
Hi!
I'm so stupid. I wanted to install cm12.1. So I rooted phone, unlocked BL. Then, I had first problem - when executing adb oem-unlock BL has unlocked and phone go to fastboot. But my comp couldn't recognize it (heard plugging in and out sound repeatedly). And here comes my "stupidity". I installed flashify and flashed CWM by it, got to CWM, installed cm12.1 zip. Of course wiped all data. Because I didn't flashed boot.img cm12.1 was freezing on fist setting up screen (nothing was working, just power button - pushing 10s turned off phone).
I wanted to flash boot.img by fastboot. But I still had problems with drivers(omap4boot didn't work). So I tried to recovery system by LG Mobile Support Tool. Everything got fine, but then phone stuck on the LG logo.
S/W Uprgade mode works of course, but I can't get to recovery now.
I'm using Windows 8.1
Any ideas?
Edit.
Ok, so I tried to install omap again. I did it, but the phone is still repeatedly conecting and disconnecting and in device manager I cought omap4430 driver whith waring mark for a while. Any ideas now?
Is it the non-animated LG logo?
This should work:

The download links for the firmware are probably not up to date. Use this to download: http://forum.xda-developers.com/showthread.php?t=2287573
If your phone still goes beyond the non-animated logo, there might be easier solutions.
It was after animation.
Anyway, I have finally solved this problem by installing new system using Bride's solution with full wipe.
Hi all,
My LG G5 is in a bootloop and I cannot even access the recovery.
I guess I made something very, very stupid. Can anyone help me? Please??
Here is what I did:
- Android 6.0 stock ROM (v10i)
- Encryption is on
- unlocked bootloader
- rooted using the official LG way => everything worked fine
- installed latest TWRP => everything worked fine
- entered TWRP and installed Nougat bootloader (LG-H85020K-Flashable.Bootloader.zip) from the v20 upgrade (I actually planned to installed FulmicsROM-4.5 and the manual said I need the Nougat bootloader)
=> bootloop
The device keeps saying "The device software cannot be checked for corruption. Press The power key to pause boot". I did that and ran
fastboot devices
on my Windows PC, but no devices showed up. I have used fastboot in the past, so I am sure that the drivers work.
I also tried LG Bridge, but it does not detect anything.
Does anyone have any idea how I can rescue my device?

Yippee! I found a solution:
- install LGUP + drivers
- turn off phone
- hold VOLUME UP key and connect USB connector to PC => Phone displays "Firmware Upgrade"
- start LGUP => LGUP detects the phone and allows to flash a kdz file
My phone works again and the day is saved!
