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

I have a D800, recently unbricked by shorting pins, and i have managed to install TWRP and download mode is working. I can't run any rom. I need to flash a KDZ through download mode.
But all the KDZ are of 10a/10b etc , does any body know where I can find a 30x KDZ or how to upgrade without flashing numerous FOTAs?
or will my phone boot up if i install http://forum.xda-developers.com/devdb/project/dl/?id=13450? i think not, but still need to know.

The AT&T D800 uses a TOT file to flash back to stock. Are you in the right section? If you have a D800 you can use this to go back to KK and it's just one FOTA thru AT&T to go to LP. http://forum.xda-developers.com/showthread.php?t=2663369
I got the phone from eBay and it has been rooted when it came out of the package. However, I failed to activate it to Sprint. The Sprint customer service representative told me to flash the original stock ROM. The current rooted software version is ZV6. I downloaded the ZV5.tot file and ZV6.img file from this forum, however I don't know how to flash them.
It seems tot file is from LG and the img file is from 3rd party, so I prefer to use tot file. However, someone in this forum said you would brick your device if you flash different version. Maybe to flash img file is safer.
Any helps will be appreciated.
Do not flash that phone with the TOT file. You will hard brick it!! Follow this guide to flash back the stock system.img, but make sure you flash the correct version! You MUST flash version ZV6. Once you flash the stock image, you can reflash with the rooted image. Although I can't see the rooted image keeping you from authenticating with Sprint... seems to work fine for me. But I would give reflashing ZV6 system.img a try. Should work fine. (I have done this process many times with no issues)
I tried to instell cyanogenmod n my phone, downloaded from the official site, once my twrp installed the package my phone presented a bootloop problem, i tried to update it using update.app of a official firmware but the combination of vol+vol-pow seems not to work, i even tried to extract images files from update.app using Huawei update extractor and then to flash them but nothing, I'm worried for the possibility ofa really serious problem, please help me.
Hi! A while ago I decided to flash TWRP and a custom rom (LineageOS) onto my S7. After a while I decided that I would prefer the stock OS. So I tried flashing the stock ROM with Odin and a zip file downloaded from SamMobile. But it would always fail when it got up to flashing system.img. So I tried another firmware using SamFirm, the same problem persisted. So I tried flashing the stock ROM using FlashFire, but no partitions showed up. Smart Switch and Kies 3 just said that my device is not compatible. If anyone can help me, it would be massively appreciated.
P.S. I am doing everything right, I've done this exact process on many other Samsung phones.
Are you extracting the AP, BL, CP and CSC files from the zip, or just putting the zip straight into Odin?
