i also got the same phone delivered today and got it from Ebay. I called LG and they were not able to help much. Let me know if you find a way to update.

Need Root
Help, please.
Got it on eBay too.
Any idea on how to root it and install any ROM?
Thanks

I got the same from ebay, the device's model name is LGL23.
surprisingly the phone gives an insanely high score of 45,498 on antutu despite having a ton of bloatware.
I wish someone (DEVs) would make a custom ROM as there's no kitkat update available as of now and we're stuck on 4.2.2.
Here's hoping there would be more development for this Japanese variant (LGL23) as there have been almost 1500 pieces sold on eBay alone since the black Friday sale.

Me too!
Many are banging L23 these days please share solution guys. I got mine from Amazon and i`m sure many did as well. Peace.

i have rooted mine
i also bought the same on ebay and have rooted this device
but not able to find a rom for the same.

Everything LGL23
Hi to all the fellow LGL23 users,
Here are some quick updates what worked for me on my LGL23.
I was able to unlock and root my LGL23 device and install a custom recovery..
AS of now I suggest to stay on original KDDI ROM version 4.2.2.
Because from version 4.4.2 you might loose some functionality (Wallet function, TV, NFC, unable to root etc.)
But having said this, the below side (Japanese only) gives some really good tips for the original KDDI version 4.2.2 ROM.

Other useful stuff
How to bump up / adjust the resolution

Use the confirm after 1 minute option to avoid messing up your phone !!
[email protected] dpi is perfectly fine working.
Above that its not reliable anymore and System UI crashes (probably due to RAM shortage)
--- What worked for LGL23 ---
Rooting Android 4.2.2:
I was able to root my device by usage of g_flex_rootkit.zip. I dont recall the download link, existing links seem dead.
The above g_flex_rootkit.zip package contains special version of Towelroot, Stump and SuperSU.
Downloading Towelroot, Stump and SuperSU separately from Google Play store did NOT work for me
NOTE: Dont update SuperSU via OTA once rooted !!
Installing the recovery rom:
http://lgviet.com/forum/threads/root-recovery-lg-flex-kddi-lgl23.29775/
Search for twrp_lgflexkddi_lgl23_lgviet.zip file
Use the recovery.lok file and flash it as recovery.img
This will give you TWRP 2.8
You can use Flashify for installing the recovery rom.

Here are my findings:
The D959 ROM is not so smooth as the Japanese KDI version.
Just no comparison.
Please also note that once the ROM is installed 2 updates will be waiting.
(Bugfix only)
However somewhere on the way you will loose root access to your phone.
I am still trying to root again and then restore my previous version 4.2.2 from KDI as the operation is so much smoother.
I can easily change resolution to 1080x1900 which I cant do with D959 ROM.
>> Unless I update the threat I was unable to root Android 4.4.2. <<
Also I was unable to confirm the following functions with D959 ROM..
- NFC
- Wallet function

How to wipe my Samsung SGS?

Hi,
I am new to this forum.
I bought a new Samsung SGS from Orange network UK which is locked.
I unlocked it in India and am using it.
I wanted to wipe off the memory as there are unnecessary apps installed.
If I do the wipe off will my mobile get locked or will it remain unlocked.
I also want to know how to wipe off the memory without getting my mobile locked..... Plzz do help me guys.............
One more thing ..........
My mobile firmware version is 2.1-update1
Baseband version is I9000BVJF3
Build number is ECLAIR.BVJG2
Can any one suggest me the themes that I can install in it and waht are they???
Hello,
Before you start flashing themes, Have a cruise around the forum and do some research regarding firmwares and flashing.
The first thing you need to do before any themes, is download a nice solid 2.2.1 firmware for your phone.
There is also a 2.3.3 that was just leaked, but is still in a late beta stage.
There's a ton of information on this forum. Take some time and do a bit of reading. You'll be flashing in no time.
ThankYou for your suggestion.
Sure I will go through the forum.
But just let me know one thing if I upgrade my SGS will it remain unlocked or will it be locked as I mentioned earlier that I unlocked it earlier.
It will stay unlocked.
After you unlocked it, check can you enter download mode press and hold volume down, menu, and lock-power button for 10-15 sec.
If you can't than you need to enter download mode on the phone from PC:
-Install Kies from official Samsung site(it has drivers).
-Download adbDownload attached to this post.
-Download Latest Firmware (with bootloader files).
http://forum.xda-developers.com/showthread.php?t=1011901
-Odin and pit (512).

HELP: Upgraded from stock 4.2.2 to 4.4 and lost network connectivity

Hello All,
Tried searching for a case peculiar as mine, wasnt able to find one so here is the lowdown.
1. Xperia C6603 , originally had 4.2.2 stock ROM which was working fine with my local network. Dont remember the baseband version.
2. Used XperiFirm to download the latest firmware as reported in the list. Dont know what does the suffix RxD (R1D--R8D) means. Anyone please explain. As per the below screenshot downloaded version "C6603_Customized HK_1270-5695_10.5.1.A.0.292_R1D" .
3. Before flashing the downloaded firmware I flashed the dualrecovery from XZDualRecovery. I made a TWRP backup of the 4.2.2 stock ROM on an external SD card, for all partitions including TA,system,boot etc.
4. Used Flashtool to convert the downloaded (step 2) firmware "FILES" format to a flashable FTF file. Flashed the firmware , which went on smoothly.
5. At the first startup I got the following screen , telling me that it is a prototype device/firmware . I went on to see that the network which was working fine with stock ROM 4.2.2 was no longer available.
I tried to go to settings to check and search for networks, which shows available networks, but unable to get itself registered to the SIM providers network. Tried all the settings combinations in menu "*#*#4636*#*#" , nothing makes it work to get the GSM network connectivity back. It is supposedly on the correct setting of LTE/WCDMA/GSM which my current operator supports. Following is the "About" screen for current baseband version.
Tried going in the "Service" menu via "*#*#7378423#*#*" , with the following info, having an unknown modem configuration.
6. Tried reverting back to the old TWRP backup, for which I needed the TWRP recovery loaded on the phone. So ran the XZDualRecovery script again (with the new 4.4 ROM on the phone), however the script hangs around in the end and never reboots the phone with the TWRP recovery. So i am unable to revert and use the stock ROM backups .
7. I dont want to root/unlock the bootloader, however I tried installing TWRP via its "XZrecovery.apk", but it requires busybox (which requires a rooted phone). So i tried the rooting script from [GUIDE] How to root 10.5.1.A.0.283 / 10.5.1.A.0.292 [Locked Bootloader], but it also hangs around in the end and never delivers a rooted phone.
8. Tried looking around for assortment of xperia Z baseband files to check and see if flashing it separately can make it work, however to no avail the the condition persists.
Either ways having a prototype version on the phone which transmits all data back to sony is not desirable at all. So need to replace it for sure. Currently I am stuck in the middle without a clue of how to go back and restore the 4.2.2 TWRP backup, or to actually flash a "non-prototype" or retail version of 4.4.x .
Any help/guidance/suggestions to remedy would be appreciated.
Thanks.
=====================UPDATE
Ok followed the instructions at [GUIDE] How to root 10.5.1.A.0.283 / 10.5.1.A.0.292 [Locked Bootloader] , read carefully again to flash the .230 kernel. Flashed the XZDualRecovery and got the TWRP recovery back.
Restored the old 4.2.2 TWRP backup , hoping that everything would go back to normal. However with a successul restore and a reboot, I was amazed to see I still have no network connectivity. The baseband version is "9x15A-ACEFWMAZQ-30110068-44" . Another noticeable thing was that after the restore and first boot, I still got the "prototype device" message again, which was not there when I first booted the device with original stock 4.2.2 ROM before this flashing adventure began.
Any ideas what may have gone bad.
Thanks.
=======================================
Just got to know that my device is a BROWN device, its IMEI number starts from 0044 so it is a prototype. Any ideas is it really good or bad to have one. Also I see that after another restore of the original stock 4.2.2 ROM it is barely getting the signals indoor (1 bar only). The signal reception is very weak and sporadic . Should i keep the device or not and is there any remedy or network signal strength.
Thanks.

Hello All,
Tried searching for a case peculiar as mine, wasnt able to find one so here is the lowdown.
1. Xperia C6603 , originally had 4.2.2 stock ROM which was working fine with my local network. Dont remember the baseband version.
2. Used XperiFirm to download the latest firmware as reported in the list. Dont know what does the suffix RxD (R1D--R8D) means. Anyone please explain. As per the below screenshot downloaded version "C6603_Customized HK_1270-5695_10.5.1.A.0.292_R1D" .
3. Before flashing the downloaded firmware I flashed the dualrecovery from XZDualRecovery. I made a TWRP backup of the 4.2.2 stock ROM on an external SD card, for all partitions including TA,system,boot etc.
4. Used Flashtool to convert the downloaded (step 2) firmware "FILES" format to a flashable FTF file. Flashed the firmware , which went on smoothly.
5. At the first startup I got the following screen , telling me that it is a prototype device/firmware . I went on to see that the network which was working fine with stock ROM 4.2.2 was no longer available.
I tried to go to settings to check and search for networks, which shows available networks, but unable to get itself registered to the SIM providers network. Tried all the settings combinations in menu "*#*#4636*#*#" , nothing makes it work to get the GSM network connectivity back. It is supposedly on the correct setting of LTE/WCDMA/GSM which my current operator supports. Following is the "About" screen for current baseband version.
Tried going in the "Service" menu via "*#*#7378423#*#*" , with the following info, having an unknown modem configuration.
6. Tried reverting back to the old TWRP backup, for which I needed the TWRP recovery loaded on the phone. So ran the XZDualRecovery script again (with the new 4.4 ROM on the phone), however the script hangs around in the end and never reboots the phone with the TWRP recovery. So i am unable to revert and use the stock ROM backups .
7. I dont want to root/unlock the bootloader, however I tried installing TWRP via its "XZrecovery.apk", but it requires busybox (which requires a rooted phone). So i tried the rooting script from [GUIDE] How to root 10.5.1.A.0.283 / 10.5.1.A.0.292 [Locked Bootloader], but it also hangs around in the end and never delivers a rooted phone.

Firstly I love the detail you have provided which would save you and me a lot of time to pinpoint the exact problem and work it accordingly.
Firstly, I would suggest that if you have a box or any other receipt that shows your exact device name with its basebands. Where did you buy it from and what is your exact location so we can guess your region. This is the time to show it now. Also which basebands work in your location can also help us out.
The problem you have made it flashed basebands of a different variant which has resulted in loss of network. So to fix it we need, and there are three ways about it.
First, download Sony PC companion and try to repair your phone and see if that helps.
Secondly, download flashtool and ftf for your device (make sure you select the right variant this time. Choosing for wrong device can hard brick your phone. so beware) and flash your phone with it.
If all this fails, you go to Sony flashtool called Emma. Download it and try to flash it with that.
You can google how to use every tool on xda and I am sure you would find a lot of guides for that.

Error
Thanks for the post, I have been trying this for a few days without success.
I hit a couple of snags after being rooted and installing the modem image as per your instructions.
1. I can't disable knox, are there more details you can provide?
2. ssu doesn't run it says "unfortunately, SSU has stopped".
I went through the dialer options anyway just to see what would happen and it appears that I still get a invalid sim card without the ability to enter the unlock code.
I figured I would do all the steps again in order to have a clean install once it's all tested and working but no luck.
Also in the step where you say "1 Debug Screen -> 6 Phone Control -> 5 Simulation -> 2 SW Watchdog <--hit this 6 times" should I basically exit the dialer with back at that moment since going back many times doesn't get me back to the menu's?
One other question, I see this is android 4.2 if I do a firmware update from T-Mobile taking it to Lollipop will I loose the functionality of the phone/modem?
Thanks!

Which version are you on and is it L720 or l720t
Disabling k ow is part of supersu so just look up another way to root your device and when you root it it's should ask you if you want to disable know just hit ok and the watchdog thing it's OK just reboot .

L720, but it never asked to disable it. Running Android 5.0.1
Also, SSU doesn't run ( I'm guessing in Lollipop ).
So I got everything working on my L720T.. My only concern is that will I be stuck on 4.3 if I want to keep LTE? I noticed the ROM I installed was actually a T-Mobile rom, any chance I could use a Lollipop T-Mobile ROM? Or is this version made to work with L720/L720T?
Hi i bought the s4 at first i didn't know if it was rooted or not but further investigations i found out it was rooted. The phone doesn't have that ssu apk nor superuser.apk which is kinda odd i ran apps that require root access and they worked fine i didn't receive any pop ups to allow access or block. I want to install a rom for which i need to install a recovery now my question is do i have to root again?
Q. How do i know what modem is currently installed ?
Q. Also at first i could see my carrie's name in notification bar now i see sprint is it locked again i can still use my sim and i am getting signals
Pease help i'm new to flashing modems.
Thanks in advance

I did downgrade the modem 100% as the instructions state, but in the end the sim card doesn't work.
Running Lollipop 5.0.1 SSU won't run, so I can't do the "unlock" part.

You have to consider your warranty and carrier support if you root your phone.
I have rooted my phones hundreds of times without issues.
Pretty much everyone on this site I'm sure can say the same.
As long as you are careful to follow instructions you should be fine.

You are correct, I started in the download section of the instructions missing the first important part to downgrade first!
New Issue: Image provided IOdin executable fails several times, I use Odin so I'm familiar with the process, do you have an image onlY?
Let me ask you, once I go through the process can I upgrade to Lollipop OTA from TMobile or some other ROM without breaking the modem functionality?
Thanks!

Has anyone been able to accomlish this?

This can be accomplished but not with his guide for he is missing some steps. Most likely copied and pasted from another thread found here:
http://forum.xda-developers.com/showthread.php?t=2530610
Use this ^ if you wish for a Domestic Unlock and a International Unlock.
Then if you want 4G LTE just follow this guides flashing of the M919 Stock ROM which is from the T-Mobile Galaxy S4.
Enjoy~

Thanks! This worked!!!, a few kinks and I may simply redo the process to be safe since there are a lot of steps.
If I put lolipop on here will I then trash it?
Since I'm not at the Ninja level on this, couldn't someone create a AOKP rom with a clean AOSP, drop in the drivers from the sprint phone ( which I beleive are really just the modem ) using the downgraded modem already unlocked and create a custom ROM? Then the user can get the benefits of keeping up with Android updates more frequently while using there hardware on the GSM platform? ( wow thats a long question )

Lollipop will work on it, the latest it has is the OD2 firmware which is Android 5.0.1 if I'm not mistaken. I'm using the exact one and it still works. As for custom roms, you can use any since the modem is just a plugin of a sort. So if you want to do that all you need is to stay on the MDC modem make sure you are unlocked and working with T-Mobile or what ever carrier. THEN flash over to the AOSP/AOKP or what ever rom you want and it should work. The only reason you need to be on stock firmware is to do the Unlocking via Dialer Secret codes. But after that you should be working perfectly fine with AOSP/AOKP. If I remember correctly there should be a GPE (Google Play Edition) rom somewhere in the Dev forum for GS4 have a look around!
Good luck.

Horrible Mistake, Need Help Fixing

Hey guys, so recently I decided to unlock the bootloader of my Moto G (XT1064), and flash a custom ROM.
I unlocked the bootloader, all good. Here's where the problem kicks in.
When I flashed the new ROM, I forgot to create a backup of my Stock. So essentially, I have no way of returning the phone to what it used to be.
Now, I'm on Paranoid Android, and my phone is getting absolutely no service. I try ADB and Fastboot, and both say that no devices are found.
I'm also on Wind Mobile. I tried using some tool I found online to revert me back to stock 4.4.4, and it worked, but I still had no signal.
I noticed something between the two times I had no signal. I hold my power button, and it says airplane mode is on. However, I am still able to connect to wifi.
When I press the Airplane Mode button, the button greys out and I can't click it anymore, and I still dont have signal.
I tried *#*#4636#*#*, and I'm unable to turn on my radio from there. I set it to GSM Auto, and it doesnt stay when I reboot.
Please reply fast, I really need to be able to use my phone. Thanks.
Are you downgrading?
I think that could be the issue

there's (i think) 3 versions or xt1064 stock rom RETCA , RETUAWS & NIIMX (candian, usa, mexico) all use a different modem files
to solve phone not found in ADB use these drivers setup programs Required Motorola drivers and ADB set up download / unzip and run the 2 programs for correct drivers /usb / adb /fastboot

Stock retail canada 5.0.2 lollipop - flash via Easy Installer below its not for TWRP or OTA update methods of updating... this is stock OEM motorola so you will get future OTA updates and (should) be able to flash straight up from 4.4.4 using this Easy Installer for Lollipop (no firmware included) - read instructions inside..
