Hi, this is my mini guide to recovery in original lg e975... If any method does not work then use this!!
I have test it on my lg e975 bricked thanks twp recovery e970 !!! kdz not working ... error!!!
1- buy this cable to set usb 910k or similar cable important is "mode 910k"(http://www.ebay.com/itm/4in1-Micro-...999-P990-P970-flash-unlock-MORE-/261019033382)
2- download LG MOBILE SUPPORT TOOL from http://www.lg.com/sg/support-mobile/lg-Optimus-G-LG-E975
3- shutdown phone
4- connect cable to 910k at phone
5- start lg support tool and install driver
6- you will see that lg support tool has found your phone
7- go in support > Emergency & recovery mode> write your imei and press check (wait 1 minute after "OK" to start upgrade tool) upgrade process is 10-15 minutes
7-after upgrade is finished it restart phone automatically
If you have change partition after update could stuck on logo lg ... how to fix it:
- shutdown phone and press hold key volume- and power for 15s and it reset software-
Sorry my bad english!!!!!!!
I have done these steps with the regular cable that came with my phone lol. No special cable needed.
you can get into the flash mode by holding down vol up and vol down while connecting it to USB.
If you can enter download mode, you can use KDZ updater,without any problems. LG mobile tool will work only on stock rom.If you are on custom rom,no luck with it.
Besides, with kdz updater you don't have to wait everytime to download the KDZ from lg server, you can use local image.
But if you can't enter download mode, the only way is the JTAG.
But if I have problems to flash with kdz and yet also "LG support tool", but I can get into download mode, how can I fix it?
I have the animated LG logo bootloop after trying to flash via kdz with CM11 installed ...
G support tool gets stuck at 15, but unplugging the USB cable from e975 and reattaching it, the procedure is completed, but say me: Battery level low even though I have 100%. Why?
Bye, Thanks
KDZ updater not working
I had TWRP 3.0.0 then i tried to flash lower version i think it is TWRP2.5.6, after i flashed it i restarted and went to recovery mode, but there was no recovery mode, only black screen... I tried with KDZ updater to flash stock rom V10H but after KDZ extracts files, connect to phone, says that its starting to s/w upgrade and my phone restarts and goes to fastboot mode, and KDZ updater stays like that, doesn't do anything, I tried it on two different computers, Win 10 and Win XP.. I still have my software on (ubuntu touch by mordesku) but i want to go back to CWM. Can somebody help me?
Hello all,
I've done a lot of googling and searching on these forums and I'm having no luck. Hopefully by asking I can get some headway.
I was attempting to restore to stock rom. At 17% of the process using LGFlashTool 1.8.6 the tool gave me an error 'Unable to Communicate with phone' after about 10 minutes of no progress. I exited the LGFlashTool program and ran it again and now it fails saying 'Cant' change to download mode". If I turn the phone off and then press Vol+ and plug in my cable it just goes to the Firmware Update screen. My phone *IS* detected properly in the device manager as LGE Andriod MTP Device and under ports as LGE Mobile USB Serial Port (COM41). If I go into recovery (Vol- and power) it asks if I want to do the restore - but it doesn't actually do anything once I say yes twice. Just sits at the firmware update screen at 0%.
I looked at this post (http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091) but it appears to be either for a different phone or different problem (showing in device manager as a bulk device - mine is not doing that). Frankly I don't want to make things worse (if that's possible)
Does anyone have a way that I can restore the download mode for this D852 phone? I'm hoping if I can get download mode to work again I can reflash the stock rom. I don't care about the data on the phone at this point.
I'm willing to send some $$$ via paypal to whomever can get me back up and running! Thanks

What happens when u just power up the phone ?
Thanks for the reply.
If I shut the phone down (by pulling battery) then plug it back in and just power it on, I get the LG logo then it goes to the firmware update screen with 'USER B84" in the box below the progress bar. Progress bar never moves. I get to this screen whether I start it in recovery (which is just the factory recov - looks like during the initial 17% it wiped out my TWRP), attempt to start it in download mode (I do not get the download mode screen with the blue dots anymore), or regularly by just holding the power button.
ok
Dont plug it into the computer and try to power it up what does ot do?
Same thing.

Ok that didn't work for me but I did try the LGFlashTool using Board DL instead of Upgrade DL and it was moving a bit. Finally got to 10% and failed at 574 sec with the error "We can't communicate with Phone". I am using the cable that came with the phone. It isn't damaged or anything.
Here's what is shows in the LG Flashtool window (this is port 1 (com41)
Code:

On the phone it shows COM41 under the usb icon on under firmware update and 0% progress. In the box below it says:
Code:
F USER 50.0 A50.0 B70 UHS
S U LG-D852 04.4.2 Hrev_10
D85210b
D85210b
That's it. Should I leave the phone connected at this point or unplug it? Device still shown in device manager (have had it up beside the LG Flashtool window the whole time. I do see it refresh from time to time but the contents dont' seem to change at all.
Ok so I left this over night and when I checked the phone this morning it's different but I don't think it's good.
Looks like it proceeded but ended with:
FBOOT Check
FBOOT Complete Time [0s ] 1th try
Factory Reset Flag = 2
Factory Reset Flag Check Fail!!!
And my phone has a blue screen with Factory Reset Status and a big red '2'
Now what do I do?
Some further information.
If I run the LGFlashTool in Board DL action mode, it seems like the process works but I end up with the red 2 on the screen. But I don't get 'can't change to download mode' or 'cannot communicate with phone' errors.
However if I choose Upgrade DL action mode, then I get 'can't change to download mode' or cannot communicate with phone'. ARGH. What gives?
I have tried things like fresh restarts (restarting PC), restarting the LG FlashTool between attempts, not restarting flashtool, etc. I can't seem to find the sweet spot.

http://forum.xda-developers.com/sprint-lg-g3/help/fix-bricked-lg-g3-ls990-stuck-fastboot-t3084562 another tutorial to try
Thanks, but no dice.
I don't get fastboot options, and if i download and attempt to use fastboot, it shows no devices.
Also, when following the steps for the BOARD DL option in the lg flashtool, it goes through the process but I get no ATT screen. Nor do I get the option to tap OK or Normal - as soon as my device reboots after the flash, it gives me a MINI OS (iirc) screen with a bunch of vertical bars below it moving up and down then it changes to the Factory Reset screen with the number 2.

Thanks - I'm going to give this a try, however I can't finda .kdz file for my phone (canada/rogers D852 LG G3) - the links in that post that link to firmware is for a tot file. Does anyone have a link to the KDZ?
Hi, I'm having the exact same problem now, where the phone only boots to the Firmware Update screen. Did you manage to fix it?
Indeed.
I used the KDZ method pacods61 posted last, but I had trouble actually finding kdz firmware. With some help I finally managed to do so from here: http://devtester.ro/projects/lg-firmwares/country.php?country=Canada

before brick my phone is on marshmallow 30b, then my phone suddenly stuck at LG logo and don't enter the OS, after that i flash via KDZ, but stuck at 99% and i just unplug from pc, after pulled battery and connect to pc it blank and show lge androidnet serialport, then i short pin/ test point and become detect as qualcomm hs-usb 9008, after that i flash aboot, primarygpt, laf, tz , etc via boarddiag, it's successfully, but i still don't enter download mode, it just show LG logo for a moment then black lcd, and detect as qualcomm again
for information:
condition i don't root phone, and now don't enter download mode, fastboot or recovery.
please i will pay who can revive my lg g3
If your phone is furbished, you have to confirm your. Model by opening and looking at the board.
You are flashing 855 firmware but that might be any other model.
Hi all
It all happens after the screen was suddenly froze and having to take the battery out.
When turned on, the phone had a red/blue led problem.
It was first solved using the LGFlashTool V1.8.6.527 to flash in the LGF400LAT-00-V10a-LGU-KR-MAY-18-2014-0 tot. The phone was reverted to the original firmware and was functional.
Then I wished to upgrade to the latest stock fw (F400L30c_00_1217) using LG Tool 2014. Unfortunately this buggy program prompted connection to server failed and the text was messed up with ????? in the pop up LGUserCSTool window. It was force closed by the system so the whole process could not be completed. I pulled out the battery again(which I now think that I shouldn't do) and after restarting the download mode was ruined.
I tried to fix it using the short pin method here and if rescued would re-flash the tot using the LGFlashTool.
The problem is LGFlashTool did not allow me to do it this time with Model Information Check Fail just like others in this forum https://forum.xda-developers.com/lg-g3/help/model-information-check-fail-t3163715
Having received the message "Model Information" fail, I thought it was due to the firmware version mismatch so I decided to give the LG Tool 2014 a try, again.
I was learnt to ignore the connection fail message to let it run in the background.
However, this time it ended up at around 65% and now the download mode has gone.
Each time the power+vol up combination ends up being detected as qhsusb_bulk, a.k.a Qualcomm HS-USB QDLoader 9008
Not sure if the pins were physically damage during the shorting.
I have a thought. Is there any tool to convert kdz -> tot?
I know there is one to extract the bin, dz from kdz but I need tot to use in the boarddiag (as I think maybe the v30c firmware information has written into the phone by LG tool causing the LGFlashTool V1.8.6.527 to reject writing in)
What is the boarddiag for? Is it performing the same as adb/fastboot to erase/flash partition?
Or are there any workouts?
Thanks for reading and helping me.
it's so weird...yesterday it was stuck at qhsusb_bulk mode
so after placing for a day, it was detected as ABD interface today
and it was booted into fastboot mode.
I managed to erase partition but not flash..tried fastboot boot twrp.img
it restarted with a black screen and this time was detected as lge AndroidNet USB Serial Port
have tried the lg flashtool but no luck
Followed by that, I had applied the short pin method to restore the partitions again..
afterwards, i could manage to get in qhsusb_bulk only...
lets see if it could be in ABD interface tomorrow
btw, any ways to fix the download mode by the fastboot method given the bootloader was locked?
I was finally able to reflash using the tot file
but after flashing the phone reboots into black screen with flashing blue/red led just like previously(bricked status)
the phone was unable to connect as LGE AndroidNet USB Serial Port too
therefore, the flash tool could not complete
any idea for a fix?

Hey everyone
My LG G4 (H815) suddenly turned off when i was using it, and it showed no life when i tried to boot it up again. Its completely stock, no custom recovery or custom firmware is installed. I cant boot into fastboot or EDL mode. I tried the button combinations as well as the test point method but i just cant get it to enter any kind of recovery mode, the screen just remains black (no backlight either). I installed the Qualcomm HS-USB drivers and when i plug my phone in my pc it gets recognized by QFIL. I tried flashing the fimware but it always gives me the Sahara unable to read packet header error. Can anyone help me?
Thanks in advance.
Have you searched the forum and tried any of these ?
