Well I suggest using the LG Suite and try to install a new update but it will remove root. You can root it again( I believe) and its not a hardbrick( like mine) so you should be fine with the update.
lg suite solution
I already try that solution with lg suite but after phone restart whole process is stooped i i have the same alert screen that i had when i try manually go into download-mode. so secure boot error, boot certificate failure or something.
Pushing files under linux via dd command
Hi guys right now i prepare some files like boot.img, aboot.img and also laf.img so kernel. boot-loader and download mode.
But right now when i check i`m not able to find under Linux my G3 i doesn't have any additional storage devices except hard-drive.
Right now my phone is able to work in few modes:
- When it turn on and boot normally (sometime): i can connect it as MTP, PTP, and charging ( but update via lg suite don`t work)
- When it don't turn on at all (boot-loop) - it`s not recognized by windows at all
- And sometimes when I leave it in boot-loop for more or less 5 minutes it goes to some orange screen that with subsystem error kernel crash and after i push volume up i theory i`m in Dload mode and phone is recognized in windows as LGE with com port but i cannot use LG flashtool 1.8 (error when model version checking, and in lg flashtool 2014 error of phone connection and process is stopped)
Any advice?? how to make phone to connect as qualcomm... to make it recognized by Linux

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?
Hey guys,
I got a little problem:
Got this amazing LG G3 on 4.4.3; got it rooted. Updated to 5.0, got stuck in a boot-loop. Tried couple of things and now im stuck on the reboot
Saying this:
[690] Fastboot mode started
[780] - reset -
[780] - portchange -
[920] fastboot: processing commands
I can access download mode.
I've tried using the LGFlash tool to flash the tot file using my Rogers D852 files - the tool says check phone or dll and that the device model is different.
I've also tried using the LG flash tool 2014 to flash the kdz file witch I got from the link with the imei - first it says cant connect that shuts down after couple attempts.
Dont know how to fix this problem
Any suggestions?

The thing is I can get into the download mode but for some reason cant restore the phone from there
In download mode phone is visible in device manager as LGE Mobile USB modem? If not update LG drivers from http://androidxda.com/download-lg-usb-drivers. Did you try different usb ports/cables?

Same problem here. When I turn my device on it says secure booting error 1003 and when I try to get it into download mode I receive secure booting error 1014. Been searching for a while but no solution as yet. I hope someone might come to rescue us.
I was able to get my g4 back to life after this sending it to a local lg repair shop (not official). The guy had a box and was able to flash the stock firmware again. Took about one hour and cost me 50 reais.

Hello everyone reading! I've tried many guides here, but none seems to work for me somehow, thats why im writing this post.
Whats my problem?
- I've been having this problem for a year or so now, like most softbricks im stuck on a bootloop while launching the phone, with red and blue led light flashing.
The message displayed in the top left corner of the screen says:
boot certification verify
Secure booting Error!
Cause: boot certification verify
How i have bricked my phone?
- I remember i have tried to unroot my phone after having cm installed, can't remeber the version though. Then the phone just got stuck in the bootloop and wont launch along with recovery.
What have i tried?
- I have tried flashing the phone to stock via lg flash tool (tot and dll) and Lg Flash tool 2014 (kdz) no luck unfortunately.
- While flashing stock F400L rom through tot files im having sometimes Milkyway connection failed error when im launching the program, but i don't think that's the case.
I'm doing everything in right order, drivers and programs installed, going into download mode, changing ports to COM41 or COM1 (neither works), launching lg flash tool 2014,
choosing suitable for F400L stock dll and tot then launching the process, unplugging the phone and after 5 seconds plugging it again.
Nothing happens, im stuck at ready.
- Tying to flash through kdz file seem not to work either, got errors after l start the flash process.
Phone plugged, in download mode, yet i get the message of program not being albe to access it, like it would have problems with connection to the computer.
Im following the instructions that program gives me though it does not help at all. It stops after reaching 4% and asks to connect the phone back after checking connection with the device.
Thanks for any help provided!
Very good,I wanted to do a downgroade of marshmallow to lollipop in A G4 H815 of a friend to root it, since Usus in linux salt told me that it could not flash, I had to flash a SALT-compatible-LAF_flash-in-twrp.zip for recovery since this model is Turkish and the official method did not work either ... well to do the downgroade in LGUP while flasehaba LAF partition (which chance ..) Windows failed and restarted alone. (Windows 7 because the 10 did not recognize the usb in any way ..) Now the mvl is stuck in the logo of the Lg with this error .. when trying in download mode the error also appears .. And it restarts again to the logo so on with this error .. I have been searching online and nothing specific for this error only if you enter download mode, but it does not enter and the pc does not recognize it when I connect it ... we have screwed but well (this happens to me for wanting to do favors ...) if you have any advice u help I would really appreciate it .. I slept 3 hours and something and I look like a zombi at work and this afternoon should return your "wonderful" phone. A greeting

Has anyone solution for this? I have same issue.
Hello,
You need to put your phone into Qualcomm Dloader mode again.
On the main board of your phone, there is a way to short-connect some two pins to enable the Qualcomm Dloader
and then you need QFIL to load the recovery files onto the phone to enable the normal android download mode.
