Back to stock...but no download mode!!! - G3 Q&A, Help & Troubleshooting

Well, I´m on Cloudy 2.5, rooted and with TWRP. The thing is that, since 3-4 weeks ago, it´s impossible to get detected my LGG3 by different PCs, and i tried with different USB cables too...I install all kind of drivers too without results.
I´m thinking maybe it´s telephone micro USB what isn´t working, so i want to send my mobile to LG Technical Support, but i have to put all things back to stock to use warranty. I can´t go into download mode, so i can´t use flashtools to flash KDZ or TOT.
So other option is to flash a stock (.ZIP) rom from TWRP and then use flashify to install a stock recovery.img. Will this work to have a stock mobile and send it to LG?
If there were any option to flash a stock rom form TWRP, included stock recovery would be great, but i think is not possible.
SUMMARY: I need to go back to stock to use warranty, but using only TWRP or other apps like flashify...download mode and phone detection in PC impossible for now
Thank you in advance!!!

you need a full stock kdz file and download mode as far as I know...

f400 download mode doesnt work
Please help i have f400k and my phone stucked. I cant get into download mode. Please help.

I tried everything...but I still have "unknown device" on my computer...
There is no way to come back to stock for LG Technical Service? Maybe with a bumped rom flashed from TWRP and unrooted? Or LG T.S. will realize and i coulnd´t use my warranty?

OK...i only want to come back to stock to use warranty with LG service, but I have no download mode, so I´m thinking other method...will be possible this????
1.- Flash using TWRP a stock .ZIP kitkat rom
2.- Download a stock recovery 10A. (recovery.img)
3.- Finallly, flash stock recovery.img using flashify
will this work? is it possible to use flashify to restore stock recovery.img ?
If i could do that, i will recover my warranty again

Try THIS tutorial to flash your kdz.. Also it's wierd because if you succesfully flash an kdz file (using any method) you should be completly (re)locked and unrooted.

i can barely remember what i was doing, im sorry
if you come from 4.4 you can flash through the lgspst from the teenybin thread the 975 kdz file by renaming it to bin, and then because you are with the ls970 dll file, you can root it, flash cwm through freegee then go to cwm and clear everything (data cache sddata system dalvik nothing else) and then go to download mode again and flash the original e975 kdz through the kdz updater, its a lengthy process but thats how i did it until i or someone else find another more short way

LG G3- Use FLASHIFY To Flash Stock recovery.img?

Use FLASHIFY to flash stock recovery.img?
I´ve tried during weeks different methods and with differenet cables and computers and is impossible that any PC recognize my LGG3 D855.
I want to send it to LG Technical Assistance (maybe micro USB connection is broken) but i need to put a stock rom to use my warranty. Now i use Cloudy 2.5 rom, and is impossible to flash a TOT or KDZ using Flashtools because is not recognized and can´t go into download mode so...would this work?:
1.- flash a kitkat stock rom from TWRP
2.- then using flashify, flash a stock recovery.img file. (i´ve tried to restore it throuhg AREC with a backup that sent me a friend of mine, but didn´t worked)
3.- finally, unroot with SuperSU
Will this work? Is it possible to go back to stock recovery using flashify and an original recovery.img file?
I´ve been with this more than a month and i´m really desperate...i need to find a solution
Thank you in advance!!!!
Even after installing the latest Windows driverset from LG, your PC still doesn't recognize your phone?

And what happens when you try to enter Download mode?
thank you for sharing master

No download mode but recovery available.

I have the lg g3 Korean model f400s and through some mysterious ways I've lost ability to enter download mode. Even the lg update tool cannot find it. Not even through recovery if I choose bootloader.
I'm running a custom Rom on 5.0.2 and I'd like to upgrade to 6.0. The phone works fine, so does the recovery.
Is it safe if I try to flash it through recovery? Where can I find such a zip file (Korean) or how can I create one?
Other suggestions would also be appreciated.
Anyone?
You can install Fulmic Rom from: http://forum.xda-developers.com/lg-g3/development/rom-fulmics-rom-3-0-tweaks-hub-ota-v30b-t3304556

E980 Problem & Need Help

I have E980 that has secure boot error, and it boots into CWM 6.0.4.4 . However, it cant read / mount external , so i cant flash anything from microSD.
So, how do I upgrade to TWRP 2.8.7.0 and flash Slim LP ( is this latest and best ROM for this device ? ) TIA
PS : does sideloading the twrp recover work ?
There was a flashable zip of TWRP somewhere in TWRP thread, but generally, best way would be to simply flash it via flashify. You can always try to flash roms from internal SD or via sideload, but I'm not sure that old CWM will work with newer zips - it wasn't working well even back in Kitkat days, not now.
You can always flash Philz CWM, and use it as a starting point, and update to TWRP as soon as possible. Not that there is much going on for this device.

Best approach would be to flash stock Jellybean, then root, install busybox, flash TWRP (can't remember if you have to flash one from FreeGee first and then update, last time I did a full reflash was long time ago), do a NAND backup and flash whatever you like after that, because half of our stuff is based on JB, even recoveries won't read KitKat partitions scheme well (kitkat has different modem partitions compared to jellybean so there is always a possibility you won't be able to backup and restore EFS, or you'll get a partial backup, because there are 3 EFS partitions).
Once you flash on Jellybean base, no further changes are necessary.
problems !!!

I got another problem while trying the LG flash tool stock ATT V20 tot file ( cant find kdz for E980 ) . I followed the guide , downloaded all necessary files, phone can be put into download mode . However, it wont show COM/Port in my laptop and show no device list in adb shell . It cant be driver problem becuz I tried to reinstall a few times and other phones can be detected fine in adb shell . Any idea ?
PS: Phone shows a yellow mark USB Composite device instead of LGE mobile com/port though .

You need LG's unified driver installed. Also, make sure that you have E980 (there are 5+ variants, all differences in firmware). Probably it would be best to download firmware according to IMEI.

Like i said i got proper driver installed and recognized by my other LG devices. I got it resolved now . The issue is with USB 3.0 . You have to use USB 2.0 for the LG Flash Tool and driver to work properly. This is also stated in the other threads . Thanks again

For owners of LGD855-V10m-ISR firmware

I know it says LGD855 but this is a LGD850 firmware. The best, clean firmware for KitKat.
And I know that a lot of you with this firmware tried to flash custom recovery TWRP for D855 and got in fastboot mode instead...
If you still have this problem and your phone was on this(LGD855-V10m-ISR) firmware, you should flash a custom recovery for d850 and not d855.
But I want to ask owners of LGD855-V10m-ISR or past owners of this firmware that never replaced their version of LAF partition, that means you never flashed another stock firmware, you could flash custom rom but never a stock rom, becuase custom rom usually dosn't replace LAF partition... so could you please backup your LAF.img partition and share it here?
I still own this firmware, I can access custom Recovery mode but I lost download mode because I accidentally messed up my LAF partition.
The only way to access download mode now is to boot another LAF partition in fastboot mode, because if I flash it i get boot certification verification error...
Thanks.
I know you asked this ages ago, bit...
I have the LGD855-V10m-ISR, with TWRP recovery for the D850. I've done a basic backup, and I'll gladly send you the LAF.img, but I don't know where to find it!
Also, may I ask you, should I flash custom ROMs for the D855 or the D850? I'm afraid I'll brick it!
Thanks,
dapeg
