[q]flash back to stock safely......

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.

[Q] Can't Restore Stock Firmware

Hi
I have a problem for a few days. The story is that I installed Custom ROM and it stop asking for unlock code when I insert a new carrier sim card. Somebody told me to restore to Stock Firmware. I used "KDS Firmware Update" to push Stock Firmware from my PC but when the phone restart to install Stock Firmware, Custom Recovery Mode appear instead of Stock Recovery Mode. As the result, it failed to install.
I'm looking for a way to restore Stock Recovery Mode but I found nothing. Now, I'm asking for someone to tell me how to do it or give me the Stock Recovery Image zip for my LG Optimus G E973.
Thanks in advanced.

Safest way back to stock

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?

Try to flash TWRP again, then restore backup

Flashing the twrp backup is fine don't worry.

[Q] A few questions about Custom ROMs

Hello everyone! I'm not really new to this Android rooting and unlocking bootloader stuff (I did this to my previous Xperia phones) but I'm "new" with it now because I'm now an LG user. I currently own the D855 Global variant.
So here are my questions:
1.) Is it necessary to unlock the bootloader to flash custom ROMs? Or is root enough? (I rooted my phone yesterday and installed TWRP with AutoRec for D855 users) I'm kinda interested with the Cloudy G3 ROM.
2.) Is it necessary to unlock the bootloader to flash custom kernels?
3.) What does bump mean? I haven't heard this term before.

1) No, you do not need to unlock your bootloader on lg g3 to flash Cloudy ROM or other custom ROMs.
You are not even able to unlock the bootloader on this phone currently. If you already
flashed TWRP go get your Cloudy ROM and flash it with TWRP.
2) Again no. Like I said you are not able to unlock bootloader on this phone currently.
But you will be able to flash custom kernels because they are BUMPed.
3) And finally BUMP is a way of signing boot image so it could be booted on LG bootlader without the bootloader itself being unlocked. All XDA ROMS for LG G3 I found here are already prebumped so you are able to download them and flash immediately.

Thank you so much! Another question tho, if I flash any stock based custom kernel, how do I get back to stock if in any case I would want to?

Before flashing anything you should always do backup with TWRP or other custom recovery you already have. If you did your backup there, just restore it that way.
In case you did not, you are able to use LG flash tool and flash stock kdz files.
Also you could backup your boot.img(kernel that is...) using app like Flashify and restore it with it if necessary.
And again I recommend doing a nandroid backup with TWRP before flashing anything at all.
