I don't understand these directions from the FAQ:
"Q. How to get back to stock? I need to give my phone to warranty services how do I revert to official LG rom?
A. Check this thread. It is the v10b 2.2 stock rom as a flashable zip package. If you can't access the recovery, then see if the firmware for your country is available here or use this tool. Download the firmware and use the KDZ tool to flash. You will find instructions to use the KDZ tool on this thread. For a picture guide, check this thread.
Also for official GB lovers, see this and this. It is a v20g rom in flashable zip package. Or if you'd rather flash v20c/g roms from LGMDP, the links for that can be found in this thread.
If you are on Optimus V, see http://forum.xda-developers.com/show....php?t=1025911
If you are on the Optimus T, see this post. Uses the KDZ method.
Q. How do I restore the stock recovery?
A. Download the original recovery zip file from here and flash it. (Yes, you can flash a recovery from within recovery itself)"
I have LG P500 from USA T-Mobile. I'm on V20 Baseband.
1)Is kdz the only way to go back to stock?
2)Which way is the safer and better way to get back to stock?
3)How (full instructions) to get back to stock rom for USA T-Mobile?
4)How (full instructions) to get back to stock recovery for USA T-Mobile?
yes you can flash a recovery from recovery, if it is a flashable zip
you need to stick with your phone not other variants of LG p500, O-1(Europe), O-T or O-V, dunno what is the T-mobile USA version, but is it written inside your phone under battery
1) KDZ is for flashing software in your phone, but beware, if you are unexperienced you may brick your phone for good, but you can try it, DO NOT PULL OUT BATTERY OR DO SOMETHING WHILE KDZ IS NOT FINISHED FLASHING PHONE OR YOU WILL HARDBRICK IT (but, I do not think someone at service will notice that, after a hardbrick, it just went dead and nothing else, nobody knows nothing)
2)if you do not know what are you doing, nothing is safe, anyway, as I mentioned, a hardbrick is a hardbrick and if you still have warranty, you are lucky
3)http://forum.xda-developers.com/showthread.php?t=1824618 search there
4) LG P500 doesn't have stock recovery(just bootloader)
if you do not know what to flash try to find a T-mobile rom image (MAKE A REQUEST-someone will post it), and first time when flashing a recovery is to backup original rom for what will come after
LGMDP will work like this, it upgrades rom when you have an older version, so try to flash an older custom rom, find an Froyo 2.2 and flash it as any custom rom, boot, conect your phone to PC, that means that you have LG USB drivers installed, start LGMDP and w8 to detect your phone, after that goto options & help, select country, carrier, phone, w8 to detect latest update, start update
in case that your phone is not detected, boot into recovery, goto mounts and mount USB, that will make LGMDP detect your phone, start updating

KDZ is generally discouraged . However if you can find a Nandroid back up of GB , then that would be the safest way . I went back to stock froyo with the help of this thread - http://forum.xda-developers.com/showthread.php?t=1955354

Your have V20 that is new baseband so any rom from GingerBread onwards is good for you . Stock recovery can be flashed sitting right from custom recovery . Check out this thread for custom recovery and ROM of 2.3.3 - http://forum.xda-developers.com/showthread.php?t=1309744 .

So I just got a new AT&T LG G2 and it got updated to the newest version of the firmware which is the D80020k firmware. I wanted to root and install Mahdi rom but I cant get a custom recovery onto my phone because the firmware is not supported (trying to get TWRP). So now I am looking to see if I can revert my phone back to the D80010D firmware. But this is my dilemma. Is it safe to use LG FlashTool on D80020K firmware to go back to D80010D firmware?
Figured it out!
I am back on jellybean! I just took the risk and used LG Flash Tool....worked fine
Quick note: the latest firmware version is 20y (20k -> 20u -> 20y).
Even with 20y, you can still root and install TWRP recovery on it.
Anyway, you got everything under control. Congrats.
BACKGROUND
LG Lollipop bootloader chain has already fixed bumped flaws. To use bumped CWM recovery with LG official Lollipop, we have to keep KK bootloader chain on our devices. However, LG official Lollipop kernel's certificate/signature does not compatible with LG KK bootloader. Therefore, we have to remove LG Lollipop kernel's certificate/signature and then bump it so that KK bootloader would like it.
After searching webs, I cannot find any update pack which has boot.img with proper kernel cmdline arguments as my Taiwan D838 20C kernel. It means they might be from other models or even from other KK ROMs. I decide to make a bumped official D838 20C kernel by myself.
DOWNLOADS
1. update_bumped_kernel_from_D83820C.zip: This update pack, could be used by CWM, contains LG official Taiwan V20C's cust.bin, tz.bin, rpm.bin, modem.bin and bumped boot.img. It is heard that LG's modem binary cannot run across KK and L kernel, so the boot.img and modem.bin should be updated in pairs.
2. updater-script.zip (optional for KK upgrade to L): This is just a supplementary script file.
WHO CAN USE AND HOW TO USE
The following operations may brick your devices. USE AT YOUR OWN RISKS.
Condition 1:
You have permanent CWM and official Lollipop LG ROM on your device. It means you still keep KK bootloader chain. Just to CWM to update the downloaded update_bumped_kernel_from_D83820C.zip file.
Condition 2:
You are still in KK ROM and want to upgrade to LG D838 V20C. Follow the steps:
1. copy update_bumped_kernel_from_D83820C.zip to another file such as update_20C.zip
2. Use update_20C.zip as a container. Replace META-INF\com\google\android\updater-script with extracted updater-script in the 2nd downloaded zip file.
3. Find LG official V20C kdz to extract system.img by yourself.
4. Pack system.img into to update_20C.zip.
5. Root you device if not yet.
6. Find a workable permanent D838 CWM recovery and install it by yourself if not yet.
7. Use CWM to install update_20C.zip.
8. Optionally you may use CWM to install SuperSU-update.zip pack.
Condition 3:
You have already upgraded to V20C by so called PURE method. It means you have rooted your device with all official LG Lollipop stuffs including bootloader. Now if you want to have permanent CWM, you will need to downgrade bootloader to KK to install CWM and also have to install this bumped V20C kernel.
The steps for condition 3 are roughly as follows. I have not trIed these steps by myself. Theoretically it should be like this:
1. Find LG official KK ROM kdz such aa 10F fw from web by yourself.
2. Extract kdz to get the following images including sbl1.bin, dbi.bin, aboot.bin persist.bin, and laf.bin. Do not include boot, modem, tz, rpm, cust and system.
3. Find a workable permanent D838 CWM recovery. Extract CWM recovery image from its zip or apk pack.
4. Extract boot.img from my download 1 zip pack.
5. Use adb shell to run su first. And then use dd command to write all images from step 2, 3 and 4 to corresponding partitions. IT'S VERY IMPORTANT that all partitions should be written together without interrupted by reboot or power-off, otherwise you will brick your device.
Here's the official OTA Lollipop 30b stock rom.

Should TWRP be updated?
Which TWRP is recommended for flashing this, 2.8.2.0 or higher? Or can I stay on 2.7.0.0?
Looks like a great ROM! Never minded stock. I am going to try this and LP Extreme.
Thanks!

Couple of questions (sorry, new to LG devices):
If this is the official T-MObile OTA we are supposed to receive soon... will we have any trouble receiving that annoying OTA update request, and the wakelocks that occur if I disable the PlayServicesUpdate services associated to them? (I don't disable them)
When you say to flash "30b bootstack", how to if I don't have a custom recovery in the first place? Get TWRP first, and then flash it?
Is there no need to unlock bootloader on these LG phones like with my Nexus 5?
I thought 5.1 was going to be the OTA from LG :s
Thanks for all your work

Hi, can you please let me know if this can be deployed to Verizon phone ?
What does the bootstack brings. I am on BlissPop with JB Bootloader and JB baseband. Can I just flash directly with twrp 2.8.6.1?

I was on jellybean baseband also .The 30 b bootstack will change your bootloader and base into lollypop so that is neccessary to work flashing the 30 b lollypop.It also flashes the latest recovery but you will loose the jellybean base and the download mode .Maybe then if we flash the kit kat bootstack we will bring download mode again .Didnt try that yet Also to get the download mode back maybe d801 lollypop autorec can do that .either didnt try that .:good:

30b Freedom tool is for those on stock 30b Lollipop. You say your on 20g. Not sure if it will work with 20g. Don't have device anymore to test .
Does this rom has any issue or bug?
Works great as long as you don't flash a backup of a rom or xposed for lollipop. Flashing a backup pops up a message saying "Secure Booting Error! Cause: boot certification verify". Then it goes to a black screen. I had to go to download mode and put stock on my phone to fix it. When flashing xposed for lollipop a stock app keeps on crashing. I forgot which app it was but when it crashes you can click ok then instantly the message pops up again. Other than those two things this works great.

When flashing xposed you have to freeze lg weather and lg cover...and when restoring kk backup you have to flash the 20g bootstack from op...and to return to lp backups from kk flash 30b bootstack...the one i linked fixed download mode

I didn't know I had to freeze those apps. How about if I'm flashing a Cyanogenmod 12 backup. Would I still have to flash the 20g bootstack?
Hello, my D800 G2 is currently running Cloudy G2.2 and I have a problem where a certain part of my screen is unresponsive. I'm not sure if its a Hardware or Software problem; but I figured I would go back to stock and see if solves my problem. So I'm wondering if it's possible for me to flash stock and then upgrade the software to the official Lolipop update (OTA) or maybe just flash straight to Lolipop. Either way I would like to completely unroot and remove TWRP; and preferably have Lolipop in the end. Any insight on a fix for the screen is also appreciated, and thanks in advance for any help with reversion aswell.
