Offline flash your stock kdz http://forum.xda-developers.com/showthread.php?t=2173465
or
Recover your phone from LG mobile support tool should remove both root and cwm from your phone.
1. Download LG mobile support tools from LG web site. http://www.lg.com/us/support-mobile/lg-P769
2. Boot your phone into SW upload mode
3. Start LG mobile support tool.
4. Connect your phone with usb cable. LG mobile support should detect your phone model. If not please reinstall LG usb drivers.
5. In LG mobile support tools, select "Customer support" > "Recover phone"
4. New dialog popup ask for IMEI or S/N. Your IMEI should already fill in textbox just click first button.
5. Wait for LG flash program to load kdz from their server and flash your phone. It should work.
thank you ,. i did that and it installed me v 20h jb version.
i sold this phone to a friend because of the poor support , and i bought something different. thanks for the help.
Hey all,
So I successfully rooted my phone, and then I was going to go into recovery reboot mode to install a downloaded rom. I'm not sure what did it, but on that restart I got LG Security error. I first attempted on three different computers to do LG Mobile Support Tool. It stopped everytime when it was going to begin downloading the files. I'm pretty sure if I still had the Security Error image, I would be fine, because I now know of ways to bypass the LG Support Tool, and edit the host file, and then get it downloading.
Either way, in my research after no success with LG Mobile Support Tool, I came across Fastboot. So I got fastboot, I got the drivers installed, but I'm pretty sure my problem was, on the command prompt screen when Fastboot asks' you questions I said yes on them. I believe this is what caused my phone to have the black screen. It will not go into S/W upgrade mode now. It will not do anything, just black screen. I found a tutorial over on Android Forums, and with using Fastboot, I was able to sucessfully flash "p4_769.img" According to that tutorial, after doing that I should have a dead android guy logo, and then just be able to hard reset... but that didn't change anything. Still have the black screen. Still won't go into S/W Upgrade mode.
Now according to what I've read, the next step would be to flash KDZ Afresh...I've looked for this, whatever it is, specific to my model phone, but I can't find anything. If anyone else has any ideas, I would love to hear. I'm so frustrated at this point. Very much appreciate any help. Thank you.
It sounds like now what I have to do is, using how I flashed that recovery img, I first should flash the x and uboot.bin files to my phone. Then I will be able to get into S/W mode, and then restore from there. I just have to find these bin files. I don't have a friend or anyone nearby with the same phone as mine that can:
adb shell su -c busybox dd if=/dev/block/mmcblk0p2 of=/sdcard/external_sd/p2.bin
with theres.

Hello,
What Firmware version was on your phone? I had 10i and I totally bricked the phone. All I have is the download mode and I can't flash any older files and everytime I try 10i the app just crash!
Did you try the software recovery through LG Bridge? Provided that it finds your phone, it should be able to do a restore to the correct firmware. It will take time to download the software off the server. I had this happen to me with the screen showing "download" etc. Taking the battery out did not help so the only way was for me was LG Bridge. I hope this works for you.
Hi I messed up with my LG G5, help needed ?
I want to tell u what i did until now.
I want to root my phone:
1. Unlock Bootloader.
2. Install TWRP
3. Messing around in TWRP becaus i dont finde the SuperSU files cause of encryption usw.
4. Want to Swipe all data and start all over again
5. bootet my device normaly and ther is just the Message "Your device software cant be checked for corruption".
I cant do anything now. I tried to factory reset the phone didnt work. The phone doesnt react to any CMD commands.
I cant enter the TWRP.
I used LG UP to flash the device but LG UP doesnt recognizes my phone correctly, neither in USB Download Mode or in the so calles status, where i just got the blackscreen with the Message"Your device software cant be checked for corruption".
Maybe you guys have a solution.
PS. Sorry for bad english
as long you can start into download mode, your device is not bricked.
this thread should help installing and using LGUP correctly.

a sign of life is the windows-sound when connecting the USB cable... there's a device shown
QUSB__BULK (not properly installed) and that's all..
I tried installing USB drivers for the LG G5 and also the Suite / LGUP / LG Mobile Support Tool / Bridge...

with 9008 he means qhsusb_bulk. The drivers you will need are from Qualcomm, once BoardDiag files for G5 are public.
were the boarddiag files ever made public?
Facing the Same problem
I am now facing the above mentioned problem. My g5 h850 doesn't do anything and the only sign of life there is when i connect it to my PC and it picks up as Qualcom hs- usb Qdloader 9008 other than that no display no sound from the handset whatsoever tried getting it into download mode but it won't show anything. I installed all the drivers and tried connecting with lg up but it doesn't pick the phone on any com ports. Is my phone completely damaged or can I do something to bring it back to life. Please help someone

QFIL needs PrimaryGPT_0.bin file through firmware extractor but no matter what stock firmware i extract I get multiple patch files like PrimaryGPT_0.bin, PrimaryGPT_1.bin, PrimaryGPT_2.bin, PrimaryGPT_3.bin .......PrimaryGPT_7.bin and when I try to get them through emmc it won't recognize any of the GPT files. That's the step where I am stuck plus I can't seem to find the mbn file for H850
I have lg v20, I too hardbricked my phone, when I extract any kdz I got 7 gpt files. primarygpt0 to primarygpt06 as you said.
are you sure we only need primargpt0 to flash via qfil? i think we need proper firehose/ programmer file and rawprogram file
Maybe I hard bricked mine:
Flashed with uppercut in download mode but with every KDZ file in UPGRADE mode I tried , after the second lg logo with sound of wellcome, it freeze and reboot over and over, it seems that crushes in infinite bootloop. Is this hard bricked?
no, this is not hardbricked. atleast you can enter into download mode.

Hi . I I would like to know did you slove your problem ? If yes then what you did plz let me know I’m having same problem with my lgh850.
I have a LG K7 that will boot to system, but no matter how many times I try, it wont boot into either download mode or recovery mode. I've tried the combos of vol down + power and vol up + power and every other combination I can think of. Pulled the battery and it didn't improve.
Anybody ever see something like this? Any suggestions on how to get it to work?

Yes, and adb devices shows nothing. I'm wondering if the bootloader is locked and maybe that's why I'm having problems.
Also, I'm having problems getting TWRP to load. Do you know what version of TWRP will work with K7?
Do you have to root first before installing TWRP from the playstore?

If "adb devices" shows nothing imo it's not recognised so not possible to flash.
Tried other cable/port?

@BigZ1 sorry, none.
OK, finally can get into firmware mode and also recovery mode. Reason I needed this is to be able to try loading custom roms on this old phone. Now I'm on to the next pothole in the road.
I would like to install twrp. twrp from the playstore wont install unless you are rooted. I am using stock rom android 5 unrooted. I've looked at all the options and from what I see, I have the classic chicken and the egg dilema. Can't flash until my OS is rooted, and cant root without flashing.
The only way out is to use adb to flash the twrp file. Unfortunately I can't get adb devices command to acknowledge any devices. I have usb debugging on, and by connecting to a windows computer, I can view internal storage. So the device is communicating, but not via adb commands.
I tried to use the LGUP tool from LG, but it wont let me select my device, It sees the correct model of phone on Com3, but wont let me select the model. I think it's because LG has turned off their servers and cast us adrift.
If anybody has any ideas, it would be much appreciated.
I think my best bet is to get adb devices to work, or find a way to root my OS. I just cant figure out how to make that work. Help, please!!!!
BTW, in the stock recovry mode, LG has removed everything useful (e.g. install zip, reboot options, wipe cache, etc.) so the only option there is factory data reset. Thanks a lot LG!!!!!

Sorry to tell you but afaik this won't work.
fastboot flash recovery <filename.img> would be the command but this will only work if it's unlocked.

I doubt that fastboot will work if adb isn't but it's worth a try.
You are right, a fastboot command would do it. Only reason I mentioned adb devices, is that if adb can't see the devices, fastboot wont either. I'll try it again, but so far no luck.
What I don't understand is why usb debugging lets me look at the internal files, but adb devices doesn't work. Perhaps you are right, the bootloader may be locked. Only thing I could find about that is in developer options I turned on OEM unlock.
Is there any other way to unlock the bootloader?
Sure wish I could get some of the LG tools working. They might enable flashing of twrp recovery or one of the various zip files that would root my OS.
Any more ideas? I'm desperate enough to try most anything....
One more question. When you try to execute adb or fastboot commands, should you be in what LG calls "firmware download" mode? Seems to me that when I did adb or fastboot commands on other vendors phones, I was able to do so while the OS was running.
Grasping for straws....
Well, it looks like you are right. There is a fastboot command
fastboot oem unlock
that would unlock the bootloader. Unfortunately while it's locked, I can't get fastboot to recognize any devices, so I can't unlock it.
Is there any way around this?

Fastboot is afaik only working in download/bootloader mode.
ADB working on any other.
So <adb reboot bootloader > usually gets you there (but adb doesn't work) or switch to it manually.
Idk if you need to flash an unlock.bin by LG.
Got it before 31.12.21 for my G5.

Yeah, I just discovered that LG discontinued support on Dec 31, 2021. So, looks like I'm out of luck for getting anything from them.
My only hope is that someone has that lockbin file and would share it. Sure wish LG hadn't left me high and dry.
Now that LG support is gone, is there any forum that might have some kind of workaround for the bootloader?
anybody got a lockbin file for K7????

Oh yeah, one more thing. The phone is still of some use to me, if I can find a way to root it. So far all the stuff I tried (kingoroot, supersu, magisk) have failed.

The file got generated by LG after I entered a long code on their developers site which is afaik different for each device.
So someone elses unlock.bin might even harm your device.
You may be right, but at this point I don't have much to lose.
One thing I would like to do with the K7, is get it rooted. I can move files to the internal storage with usb debugging. I can't install any zip files and that makes it really difficult to find anything that can root it. Thanks again to LG for reducing the recovery menu to "factory reset data" so the phone has almost nothing useful.
If you can figure out a way that I can install zip files, please let me know.
I can't find anything that will let me flash the device without root, and I can;t get to root without some tools in the recovery menu.
Thanks
OK, I have not found a way to root. So I thought I'd take one last look at flashing/upating the firmware. I found a .kdz and a .tot file that I'd like to try. At this point I'm not risking much because the phone isn't worth much to me as is.
So, if you had a .kdz and .tot file to try out, what app would you use to flash it to the K7?
I tried to get LGUP to work and LG flash tool, but cant seem to make them work. If I knew what one to use, it would narrow my search. I'm trying to flash the K7 firmware by running exe files (LG UP, LG flash tool) on Windows 10.
What do you guys use?

So, I managed to find a patched version of LG flash tool (2.0.1.6) on this website (thanks to member ieatacid), that doesn't give me errors immediately after I open it. The first thing I notice is that it doesn't appear to recognize the K7. If I try checking the box for manual mode and adding the file I want to flash, the click start, it tells me to "select model dll file". This is probably a result of flash tool not recognizing the phone. Anyway, where am I supposed to find this .dll file? I've searched everywhere and came up empty handed.
Can anybody give me some enlightenment on what I am doing wrong? Any help at all will be much appreciated.
Is there a tutorial on use of the flash tool? I looked but haven't found it yet. Just some youtube videos that are terse and lacking in detail.
Thanks!

I don't know why I didn't think of this earlier. I own 3 LG phones (LGMS300m1, LM-X210ULMG10r. VS500PP9). I tried all 3 with LGUP tool. The tool recognized 2 of the 3, and failed to ID the LGMS300 (K7). Anybody got any ideas why the tool would recognize some but not others?
I am the only owner of the two phones that LGUP would ID. I guarantee that the bootloader on them was never touched (unlocked or locked, in any way). So that's not the answer.
It would be a big improvement for me, if I could at least get the LGUP tool to work for the K7.
BTW, I tried all 3 phones on the 2016 version of LG Flash Tool. All 3 failed to be identified.
Please, if anybody has a hypothesis for the odd behavior of the LGUP tool, I would love to hear it. Any suggestions are welcome.

Update on the never ending saga!
I found (on this website) an LGUP tool (version) that is for the MS330. So it works (albeit not so consistently). I was able to flash a .kdz file after several trials. Apparently when LGUP connects, it puts the MS330 in bootloader mode, waits 15 seconds for the device to respond and then begins flashing.
Now, here's the problem. I have a .tot file I'd like to flash. When trying to flash a .tot file, 15 seconds is not enough time for the device to respond, and I get an error for what appears to be an asynch error. That is to say, the MS330 took a second or two more that the 15 seconds to respond saying, yes i'm in bootloader mode.
Is there any way to give it a bit more time? Surely the members who use LGUP tool would have encountered this behavior, and would have found a solution.
Words of wisdom, anyone?
