I am using LG L Bello D331 on Android 4.4.2 KitKat and D331 got no OTA software updates unlike other versions of basically the same phone (I heard D335 ROM works when flashed on D331).
I was wondering if there is a way to flash the 5.0.1 LG ROM without PC (my phone is already rooted via KingRoot).
P.S I'm a newbie and I never flashed anything before.
Hey! You must do it on PC. I did it just yesterday, here's how i've done it
You'll need two things:
-Stock firmware (.kdz file) you can find them here: https://lg-firmwares.com/lg-d331-firmwares/firmwares/
(just download the CIS region file, I downloaded it too :good
-Lg Flash Tool: https://forum.xda-developers.com/showthread.php?t=2797190
-Also Lg drivers but i think you already have them
After you downloaded the kdz file, open Lg flash tool and connect your phone to pc via usb.
Change phone mode to emergency, select the kdz and choose CSE flash (this will erase all your data so do backup first)
On the new windows choose start, choose langauge and here you go. Afyer 20-30 min you will be done.
Good luck!

Hi people, ive flashed the v28b bin through LG flashtool but the phone does not boot. it Just hangs on the LG logo and thats it. I cant flash through the KDZ method because the KDZ firmware updater application keeps crashing after it extracts the KDZ. I've also tried to update through the LG software update tool but it says the software i havde is the latest one. Any help would be appreciated

Just try egain, dont flash bin and fls files at same time, just flash only bin alone and wait until you get 100% in flashtool, at that time the phone will boot itself.
i managed to get it to come on after flashing it about 10 times but then i came across another problem. I got no signal and the phone would just shut down on its own after 5 mins say so i flashed xbsa's V7 rom and now the phone wont boot again. its driving me crazy!
READ THE GUIDE STEP BY STEP and it will work
Send from my XBSA ICS V7.1 P920.

I have, when i flash the V21EBOOT.bin it works fine and the phone switches on but this one seems to stick at the LG logo. It did eventually come on after flashing it over and over but then would just shut down automatically and no signal. When i flashed your rom on top it doesnt start up. Im going to flash again when i get home from work but this time without the CP file and hopefully that will work
try to flash the Korean version first with LG flash tool then restore factory settings by pressing ( HOME, VOL + and POWER button ) at the same time then flash official ICS V28b with LG Flash tool
use LG ROM CONVERTER to convert .kdz rom to .bin and .fls rom ( for easier flashing )
i did these steps and the phone woking fine

Yeah i guess i could try that, the XBSA404.bin worked when i flashed that previously. I have been flashing V28Broot.bin from xbsa instead of the official one but i'll try the official one instead
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 . If you wanna try lgmdp look at this - http://forum.xda-developers.com/showthread.php?t=1324105
I need help to install official ICS on my LG P920.
The official software updater is not working.
It says cannot connect with phone sometimes and other times it says software up to date I do not need to update.
Right now I am running 2.3.5 version of android.
I have international version of phone.
Thanks
use LG flash tool very simple
or use KDZ software updater
but you need to manually download the software in the form of .bin and .fls ( for lg flash tool ) or in the form of .kdz ( for KDZ software updater )
google it
here is where you can download the .kdz file
http://wittgenstein.homeserver.com/index.php
and try this method to flash it

My device was on Future V3.1(Lollipop). I flashed a recovery for 5.0 and installed Drake V1. All went well but model number changed to D838 . I again flashed same recovery in Drake v1 and flashed this rom http://forum.xda-developers.com/lg-g-pro-2/development/china-g3-v1-d838-t2979376. As per title it is for D838 but someone had commented that it is working fine in his F350. After flashing once i tried to boot the device it refused , after LG logo it showed security error and switched off. Recovery actions so far done by me:-
1. Downloaded latest kdz for F350S20b(Lollipop kdz since v10e is not available on web) , flashed it via LG flashtool 2014 but flashing interrupts at 2%
2. Downloaded tot and dll for v10e eidted tot using this guide http://forum.xda-developers.com/lg-...ssdl-error-t3020455/post59010479#post59010479 but it gives cross dl error.
3. Ph shows USER SO.O ASO.O B99 UHSS LG-D838 04.4.2 Hrev_10 D83810F at screen at the time of flshing tot.
I have tried all possible methods only option left is to flash D838 tot file in it . I just want to know is it safe to do so and what is going to be appropriate tot file for that. Moreover any other helpful option will be highly appreciated.

Try flashing correct TOT file for your model? (without editing)
D838 - D838 TOT
F350 - F350 TOT
Finally unbricked my G pro 2
editing tot was not doing the job , i downloaded latest kdz for my device and tried to install it but installation did not get past 2%. Finally i edited kdz using hex editor and changed F350S with D838. Flashed using Lg flashtool 2014 without connecting to internet and voila.

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.
