Hi guys, I have european e975 and would like to go safely back to stock, but i need help.
I tried to flash the new V20A stock KDZ via vietnamese easy method http://forum.xda-developers.com/showthread.php?t=2797190, but the tool just can't connect to the device, i tried everything, even fidling with COM ports.
Also I made backup with TWRP of V10H, but now the phone has CWM and CM11 and i don't know if i should use the backup.
tl;dr: Safest way/method to flash back to stock?
ThankYou )
Try to flash TWRP again, then restore backup
Flashing the twrp backup is fine don't worry.

Is there or ever will be a way to flash back to stock safely witgout the possibility of softbrick device or having to do a hard factory reset just to get the phone to boot up successfully? I'm comming from xperia play and for xperia devices its so simple via flashtool or for my friend who had a SGS2 who wanted me to flash a custom rom on his phone and that's how I discovered ODIN. Basically what I'm trying to ask is will there or is there already a standard easy tool or something that will allow us to flash back to stock easy as 123?

.KDZ method worked as easy as....well....like you say 123. There is another method using factory .tot images, which I have no tried.
Unlock bootloader -> custom recovery -> nand backup.
In case of emergency, loading into the recovery, restore nand backup.
Hi I need help. I recently got this phone.
Rooted it with stump root, and flashed TWRP 2.8.4 using flashify.
I tried to flash a custom rom, but the wiping data part had an error. Stupidly enough, I proceeded to flash the rom zip and it got stuck flashing so I had to power it off. Now my phone is stuck on the boot logo. The only thing I can do with it is turn it off, or enter download mode. But I can't enter recovery mode. I read somewhere that it is possible to go back to stock recovery using the flashtool. Problem is I don't know which firmware I have. The only information I had about the firmware was that it was ls980vze because that's what I saw when I was flashing something. How do I deal with this? :crying:
p/s if there's a way that I can access twrp, maybe that' would work because I made a nandroid backup before. Don't know if that's useful though.

Okay, quick and easy.
There is a zve tot, though before we do much. Custom ROM as in which one?
Anything CM based is radio zv8, if it is a cloudyfa ROM; you can be zva to zve radio.
So depending on which can save trouble.
Root, depends on which version you are. Zv8 - go with ioroot25. Zve - use stump root.
Next thing, forget flashify. Sometimes it works sometimes it doesn't. Tried and true method, Auto-rec. Only after root.
Upgrade TWRP through TWRP by gator's zip of bumped and such. Or use TWRP app.
Again if your zv8, flash your CM based ROM of choice.
Zva-zve, flash your stock based like cloudyfa's Roms and such.

I tried to flash Validus ROM so i'm guessing that's zv8? I am rooted btw. Wait so you can upgrade twrp by flashing another twrp file? When I used flashify, after flashing the 2.8.4 bumped twrp it rebooted to my current twrp 2.7.0 and flashed it so I thought it was just the same. I'm pretty sure I am zve. Can I flash a zv8 rom if I have a zve rom? How do I get out from the bootloop?

Basically you're stuck using the ZVE tot to bring it back to factory. Be sure to boot it at least once as the phone will have to re-activate itself.
Try the zv8 modem

And if not, then try you and always check the op carefully before flashing.
Hello everyone,
Last week I flashed CM12 onto my G3, I have TWRP installed as my recovery.
I may have to send my G3 in for repair and if so plan to use the LG Flash tools to do so. I am worried that by doing so I will lose my EFS and modem. I flashed just the CM12 rom and Gapps, so would the stock modem and EFS still be the same as before I flashed CM12? I can currently backup both using TWRP, but will this modem and EFS be correct for my application of restoring back to stock?
Thanks to anyone who helps!

Hi there.
Your EFS never changes it does not matter which ROM you flash. Before you bring the phone back to stock with LG FlashTool please backup your EFS with TWRP!!!
Secondly, if you haven't flashed any other modem (I assume you were already on Lollipop before flashing CM12) then the modem is the same as stock. Please backup that also with TWRP!!!
Save both the EFS and modem on EXTERNAL MicroSD card or better transfer to a computer.
Lastly is that you must choose the right KDZ or TOT+DLL file for you phone!!!!!! When you bring back to stock anyway, both the EFS and the necessary modem will be included when flashing with LG FlashTool.

Hello Peeps,
Ik have a E986 with a problem
When i rooted my phone and run freegee i only see the options of installing CWM/TWRP or Backup/Restore EFS.
There is no option to unlock my bootloader.
It is still possible to flash a recovery and a rom, but i can only boot into the recovery.
The only option is to flash a stock KDZ file and return to stock.
I've used freegee and different roms succesfull in the past, but because a soft brick i had to return to stock.
I sometime back tried to flash a new custom rom and new baseband.
somehow the flashing of the custom rom and baseband was ok
BUT
my recovery and root is totally gone.
I tried ADB and LG tools to revert back stock , but cannot.
It just hang at bootloader if try flashify or
display not same model if use LG tools
Please help
