First of all you need to have fastboot enabled on your phone. This is a special boot mode that is disabled by LG. To get it you have to flash your phone with a fastboot-enabled rom. After that, camera+power will put your phone into fastboot and you will be able to flash recovery.
If you're somewhere in Europe, here's the current Europe Open ROM with fastboot:

Okay thanks
And now the next stupid question :-/
On my HERO I flashed new ROMs using recovery
How do I flash a ROM on my LG ?

you can flash custom roms via fastboot or if the developer has made a recovery backup you can flash with that

After alot of googling, I found KDZ_FW_UPD
it got it to work

[Q] Flash new bootloader

Hi there
So, I can't enter recovery when I go into the bootloader to do so. I click 'recovery' and it just shows the black start up screen with the google logo. And nothing else happens. Ever. I reflashed recovery, and was able to get into recovery to install a new rom. However, after that one time, I was once again, unable to enter recovery. Now I haven't the time to be reflashing recovery just to get into it every time I want to, so I looked for a solution.
I did some reading around and apparently it's the bootloader version I'm using. (According to post five in this thread, and my assumption that I'm having a similar problem to this thread's OP.
Now if that is the solution to my problem as well, I need a bit of help. I can't find a file for the old bootloader, nor do I have any idea how to flash an old bootloader. (And please know, I wouldn't be asking had a google search not come up fruitless).
EDIT: Would flashing a completely stock 4.4.2 image update my bootloader? I wouldn't mind doing that, rooting that, and then just installing purity rom or something.

Hi Mate ,
I been looking for the same but for other reasons , to flash it is not too difficult for what i see in this thread tell how to do it manually:
http://forum.xda-developers.com/showthread.php?t=2150251
or
http://forum.xda-developers.com/showthread.php?t=2417097
in the first one they even have a zip version of it which should install like any other zip from recovery
Also you can use a tool kit like NRT which makes life a lot easier once you got the bootloader image...(advance utilities)
http://forum.xda-developers.com/showthread.php?t=1766475
My problem is that i do not know where can i get the different bootloader images...
To your question i think so , bootloader should be included in the factory image......downloading one to confirm.
also check this information

If you download the factory image, extract it, the bootloader is in the folder. Then just flash through fastboot. Just make sure you download the correct bootloader for your device

For anyone reading this thread, my solution was too move to the 4.32 bootloader from JWR66V. I flashed the .img file from this thread using Wugfresh's fantastic toolkit. (linked to in the 2nd post of this thread).

I would recommend learning how to use adb and fastboot. Toolkits do not always work as expected and you will then need to use fastboot to fix it

Stuck in recovery after OTA but stupidly formatted SD card...need help please!

Hi all,
I have an LG D802, was running standard ROM just rooted and with PhilZ recovery. Well I was silly and tried an OTA update, and got stuck at recovery...unfortunately I panicked, cleared everything and tried to flash another ROM but I'm still stuck at recovery.
I tried the instructions in the thread about being stuck after an OTA update but as I;ve formatted the sd partition it didn't work.
I want to go back to stock, I just have no idea how....I have ADB access though if that helps! I'm not really experienced in this kind of thing so please dumb it down for me!
Any help much appreciated!

can you get into download mode either try the adb reboot download mode or turn phone entirely off and hold volume up(only volume up) and plug it into the pc usb, if you can use the back to stock guide to get your phone working again

have you tried adb pushing/sideloading a rom and flashing to see if it helps?

Yes trued flashing a custom ROM, however in my haste to try and stop the OTA forcing me to recovery I may have formatted some partitions I shouldnt have.
Can I restore everything by downloading the kdz with all the correct IMG files in, converting to a flash able zip (saw a guide on here) and trying that?

[Q] Corrupt boot partition aka aboot

Hi all,
I want to install custom kernel on SHV-E330L, if custom kernel malfunction then phone will not boot. So i want to confirm in which state phone will be, on galaxy s4 startup logo or will not power on at all?
I think aboot and recovery both are bootable partition so it is possible is aboot is does not work then phone can boot into recovery through recovery partition or start in download mode?

Can you still access recovery and download mode?

Ahh, okay I see now. If there's a problem with your custom kernel then all you need to do is boot back into download mode which will still work, and then flash the kernel that you were using before again.
So basically, have a copy of a kernel which you know works on your PC ready, in case you have a problem and need to put it back to the way it was.
You shouldn't have a problem though, as long as the custom kernel which you want to install is for the correct android version etc, it should work fine. I've never had such a problem.

Thanks for clarification, please tell me that recovery partition is also bootable so if phone can't boot from 'boot' partition so is it possible to phone to boot direct from recovery?
Also please give me an idea if you u don't mind what will b consequences if i try to install GT-I9506 kernel and modem on SHV-E330L?

You can only restart the phone from recovery, not boot from recovery. But as I mentioned above, as long as you've got download mode your phone isn't broken. You can mess up anything on your phone, as long as you don't break download mode it's recoverable. You pretty much need to do something really stupid to lose download mode.
Stupid things that could make you lose download mode and completely brick your phone include, but are not limited to: flashing a kernel made for a completely different device Or selecting repartition in Odin but not adding a PIT file.
Never install anything that isn't made for your exact device! There are exceptions, but if you don't know exactly what you're doing then you're just asking for your phone to be bricked. So don't.

got my g2 d800 and i want to root and flah a rom but have many questions help...

ok guys got my att d800 and i want to root and install recovery and a rom.. am not new at flashing but the way g2 is i am.. well first of all am pretty worried about refurbished. i really dont want to open the phone.. i have checked the thread about refurbished phones... well i got mine from craiglist. black 32gb. it had everything except the charger.. the box manual and a how to use guide, a at&t sim card in a little bag with a metal g2 with pin. ( i assume this is to open sim tray).. i cheked phone imei on dialer and it matches, i used online phone imei and it matches ive checked the box and it matches.. if i go this way and trust this way, will i be able to recover phone back and unbrick if it does?

Well, first, welcome in G2 forum !
Ok, so about your questions:
-First step, yeah, backup your EFS partition -> use this thread, thanks to @autoprime: http://forum.xda-developers.com/showthread.php?t=2451390: it will backing up the partitions on your phone, then you MUST MOVE those backups into safe place, such as an external hard drive.
-Second step, yes, when you make an Nandroid Backup, it's located in "/sdcard/TWRP/BACKUPS/your_phone_id/", so if you provide to do "risky" things, do the same as the EFS, move your backups into safe place: if you want to be able to push it when in recovery, you must use a recovery that use the MTP protocol: the latest TWRP use it, so flash it into recovery (see my signature to link for TWRP, BUT USE THE 2.8.7.1 VERSION, 'CAUSE THE 2.8.7.2 SEEMS TO HAVE A BUG THAT WIPE YOUR DATA).
If you experimenting a bootloop for example, boot into recovery, plug your phone, and you'll be able, after LG's drivers installed, to push the backup from your PC to your phone.
Here if you got any questions mate!

Hmmm, nice dude, you make things fast !
But be sure every time you download a ROM to download the correct version for your model, and also, check some posts into the ROM threads to see how you can go back to stock, etc. Always good things to do !
