Hi I'm a noob who just bricked my F240L (korean ver.):crying: I somehow wiped my system partition and the result is disastrous; KDZ flashing is impossible via R&D / support tool and I can't even get into the recovery mode. Only download mode is available.
I heard that it could be fixed by using NPST but I only can find the files for E980 at
http://forum.xda-developers.com/showthread.php?t=2272177, not 240x series. Moreover, KDZ files for OG Pro cannot be extracted by using LGExtractor so there is no way I can get this file by my own.
So is there any possible way for me to get those files??
-------------------------------------------------------------------------------------------------------SOLVED----------------------------------------------------------------------------------------------------------------------
How to solve it ? I'm also having the same problem
I got the same problem also, mine is F240L (Korean version)
The differences is I can manage to enter CWM, but the CWM can't mount external SDcard. As if my MicroSD doesn't exist.
I got no backup file to restore via CWM 6.0.3.3.
Using R&D Tool to flash, after 10s update process. Appear error message "Insufficient Battery Level to Proceed", that's strange because the battery is 100% full.
Using KDZ Updater, the error message appear "File Extracted Error" for 2 KDZ files I got (10T and 10V).
Hard Reset didn't solve the problem.
Now I'm stuck in DOWNLOAD MODE and CWM 6.0.3.3 (can't do anything in CWM).
Before entering CWM, there's an error message "Secure Booting Error ! Cause : Device Unlock, so Boot success !"
Please, anyone would be so kindfull to HELP.
@stupididiotism can you explain how you solve it ?
@chimmot307 have you ever tried this version to flash (translate from chinese)
so my phone was bricked (only download mode available) 1hour ago:
go in download mode->install LG support tool->in menu go to "customer support"->"recovery phone"->(your imei should be here or enter it if not)->click check
and now wait it download the whole img and flash it for you
The firmware 10T in baidu.com is broken, asking for username and password to resume. Little HELP with the username and password, fellas ?
I follow your advice go to "customer support"->"recovery phone"
After 10s update process. Appear error message "Insufficient Battery Level to Proceed", that's strange because the battery is 100% full same with 2nd battery whose 100% full also.
It seems LG Corps. tried to block anyone outside Korean to update their phone (I live in Indonesia, got this phone from real Korean people who sale this phone in Indonesia illegally, because Indonesian market is E988-16GB storage compare to F240L more spacious).

Following your 1st advice, I managed to download the KDZ from baidu.com, and run the tutorial step by step. Everything runs smoothly.
Thanks in advance @smaybe. I owe you BIG one.
:good:
For those who got stuck in DOWNLOAD mode, you can follow these steps (in attachment).
LG PC Suite won't recognise my device (in DOWNLOAD MODE), it only recognise when in LG SOFTWARE MODE (Settings => PC Connection => USB Connection Type => LG Software).
So I can't go to Device => Firmware Recovery.
Why did you delete the 1st advice, @smaybe ? Totally recommended.
hi guys
I was in the worst condition : wiped system partition and moreover, I hard reset my 'rooted' phone.
Recovery mode not supported and kdz flashing also not working.
Then I found this divine tool called 'LG mobile flash tool v1.5' and I could find the tot and dll files for F240 series from some china website (I paid for that tho)
So my point is if anyone holding F240L and having the same problem as me. Then I can send you the files. I feel like posting the file here is a violation of intellectual property of the chinese devleoper(?! what am I saying?)

It's strange I will look after work but for me it recognise even in download mode
I deleted because I thought the last solution is easier i will take it back
LG PC Suite sucks
I've updated to the latest version, it still doesn't recognise my F240L (in SOFTWARE MODE), it said "Need to change with the right cable" even when I swap with different USB cable.
Or maybe my Windows 7 Ultimate (64bit) having problem in compatibility with PC Suite that won't recognise the USB. Cause, I haven't try with different operating system (Mac, or Windows XP)
Stuck in U+ LTE Logo
Dungeon Hunter 4 messing my Optimus G Pro in this thread http://forum.xda-developers.com/showthread.php?t=2380374
So I decided, to wipe system & data partition.
Hope that KDZ Updater will bring it back normal the way smaybe told me to.
KDZ Updater show 100% Finished, but my F240L still stuck in U+ LTE Logo.
So I try new LG Mobile Support Tool, Upgrade Recovery => IMEI=> OK. Updating to 1.69 GB, 100% finished, still stuck in U+ LTE Logo.
I haven't try LG Mobile Flash Tool 1.5, maybe stupididiotism could tell me step by step ! And not to forget to send the TOT & DLL files.
This is my email : [email protected]
Thanks in advance.
LG Flashtool Error Message
I run LG Flashtool according to website http://forum.gsmhosting.com/vbb/f177/lg-flash-tool-free-no-need-b2b-user-pass-1628819/index2.html
Extract F240L10t_00.kdz from Baidu.com, got 2 file :
- LGUP_GKV.dll
- F240L10t_00.dz
So I used those 2 file in LG Flashtool ( I don't know if those the correct files to use in LG Flashtool, cause I can't seem to find DLL file for F240L, but I think for S/W file is correct ).
Used port COM41 to flash (DOWNLOAD MODE is activated on F240L). Then I unplugged the USB cable for 5s, and replugged it. Error message appears as follow.
Am I using the correct DLL file to flash ? If not, would you be so kind to upload the DLL so I can flash my F240L ?
Thanks.

Hi all
I have done my best to search all the possible solution on xda as well as google, and I don't think I found the answer.
Basically, my phone (for some unknown reason) now suddenly have the boot loop issue.
I first tried to use the LG PC suite, but it is never able to find the phone when it is connected in download mode.
I then tried to use the LG Flash Tool v.1.18 to flash a stock rom in download mode, but failed, due to the following error (of course USB driver is installed, and COM41 changed)
Code:
PID: Null
IMEI: Null
Model :
DLL: D855
BIN: LGD855AT-00-V10g-222-99-JUL-14-2014-16G+0.TOT
SWV:
SWOV:
Model Information Check Fail
000000000
Finally I use LG Flash Tool 2014 to flash a stock KDZ image, using CS_emerengcy and CES flash, the KDZ image is obtained from the LG dev using my own IMEI. This method actually works, but after it reboots, and goes into the Android Setup wizard, it restarts itself and stuck in boot loop again!
So what may I do please? I am very stuck and have no clue.

Did u try booting into recovery and doing a factory data reset after flashng?
Hello hello,
I unlocked bootloader, installed TWRP 2.8.7.0 (adb -> fastboot method) and then I flashed SuperSU 2.46 zip. After reboot from TWRP my phone stuck.
I can't access TWRP or i don't know how to…
System isn't starting BUT sometimes after few minutes of seeing LG logo i see standard wallpaper and suddenly animation freezes. That's all.
When i go to recovery mode (voldown+power, release power and press power again) I can "do" factory reset. I choose 2xYES and i see green android. Then phone is restarting but i should enter to TWRP, right?
I tried to flash stock system (kdz, tot, dz) via:
- LG Flash Tool 2014
- LG Flash Tool 1.8.6.527
- LGUP
- LG Bridge
but nothing…
My phone PID and IMEI is null :/ (and "CUMSS" to :?)
I tried fix that with QPST (2 different versions) but in device manager my phone is only detected as COM port. No "Android Device". I can't read and write anything…
adb isn't working
I tried all USB 2.0 ports, different drivers, roms (even not for 815), dlls.
I fought 3 days and still have brick, not smartphone
I have only download mode working.
I can send commands to com port (Send_Command.exe) but sometimes nothing happen, sometimes i see "fail" after sent command.
Any ideas? Can I install recovery through download mode? Or maybe somebody know how to send files to phone in download mode but without adb?
I had stock rom MM V20L. What else you need to know?
Thanks for any suggestions, sorry for chaos in post and my english.
After trying different roms in different programs with 3 versions of dlls and different drivers…
I found solution: just reinstalled .NET Framework and then finally i flashed by LGUP (refurbish, v20L, kdz, dll 0.0.3.23)!
Welcome back H815

LG G4 Model F500L Stuck on download mode After Downgrade
Hi
i have a problem with my LG G4 Model F500L i try to downgrade from Marsmallow to Lolilpop By Flashing with LGUP Tool when i flash it. it error at 16% boot fail. So i disconnect USB and pull out battery and when i turn on it stuck on download mode.. i have try to flash with any firmware and any LG Tools but it's still fail at writing boot step i had try with Optopus box but it's still fail at wrting boot fail what is the problem . i need help now.... i just bought my phone for a week. Thanks for your helping ....
Hey guys,
So I've searched for this over and over and I cannot seem to get it to work. I've looked at simlar threads and tried what they suggested with no results.
I tried to downgrade my g3 from marshmallow to lollipop using the LGUP method. Everything worked great as far as the flashing process goes. When the phone restarted, I got the android logo on its back with an exclamation mark.
I got into recovery and the message was cannot mount to partition or somewhere along these lines. I can't seem to clear cache, the phone just reboots and factory reset does nothing.
In download mode I tried the following:
1. Using the LG Flash Tool, I am using the correct dll and tot files for the 852 and followed the steps correctly. Everything works, I get the yellow light and after I disconnect and reconnect the phone I get an error message
Donwload Fail ! (3 sec)
PID: NULL
IMEI: NULL
DLL: d852
BIN: the right file is showing
SWV: the right file is showing
Initializing
USB Connection Established
Start Download
Open Packet Error No : 0x8000000064
2. Using the KDZ method using the LG Flash Tool, select the file and CSE Flash
After analyzing and such I get an error essage as well at 2% and it fails.
3. Using the LGUP method with right KDZ file. and you guessed it an error message.
Im not sure what else to do or where to go. Please help. Thank you very much in advance and your help is much appreciated.

Hi, I've been trying to fix my H818N from the past couple of days.
Here is what I did to brick it, unfortunately
1. Downloaded Nougat 7.0 TOT file (H818P v29a TOT) from this website: androidsage lg g4 android 7 0 nougat firmware
2. Started my G4 into download mode and tried to load this TOT file using LG UP, however, LG UP stopped me by displaying an error message: Invalid TOT file
3. Then I used WinHex to change H818P to H818N in the TOT file and saved it
4. Now I was able to upload this file to my G4 in Refurbished mode using LG UP, the upload completed, phone rebooted and displayed: Erasing
5. After that it is stuck in download mode (If I restart it, it displays LG logo and starts download mode automatically)
6. In Download mode, my phone displays this at the bottom of screen:
U 633A s12. 0 AS10. 5 B100 UHS
S U LG-H818N 07.0 Hrev_10 .CPU4
H81529a
Here is what I did till now without any success:
1. installed the latest LG drivers, LG UP, and LG Flash tools on my PC
2. Tried to Flash the following firmwares using LG UP/ LG Flash Tool (I also extracted the dll file from each firmware one by one and placed in the model folder for LG UP while trying)
H815 V20o Modded.kdz
H818N10l_00_0113.kdz
H818N20f_00_0818.kdz
H818N20h_00_1019.kdz
H81520p_00_0403.kdz
H81820p_00_0314.kdz
Hong Kong H818N10b.kdz
H81520p_00_0314.kdz
H815TR20g_00_0428.kdz
F500K20C_00.kdz
All the firmwares get stuck at Internal command failed 9%, 11%, 24%
3) I have scoured the internet but wasn't able to find a solution yet
4) I even tried using the fastboot mode but unfortunately the bootloader is locked and I cannot erase the recovery or image
Now I'm not sure what else can be done to bring my phone back to life. I might try to get it into Qualcomm 9008 mode and try to unbrick it by following this guide: pakfones unbrick lg g4 hard bricked
Any help on this will be much appreciated
