[Q] Trying to install custom ROM with SECURITY ERROR - LG Optimus Black

I see there are a lot of articles saying how this should be done but at least in my case I haven't had luck with any of them.
After you read this you must realize I'm a noob on this.
I have ICS 4.0.4 Stock Firmware from TELCEL, Mexico and I'm having no luck getting the custom ROM installed or at least downgrade I think it will be better. The main problem with the phone is the battery life and it's slow, all after the phone upgraded to ICS.
I will do anything you guys suggest if you could please point me in the right direction.
A few things I've tried:
I've Rooted the phone using Unlock Root application suggested by one of the post I found here.
I've Installed ROM Manager and flashed the CWM Recovery Touch tool and followed the instructions to use a Zip, I was trying with the Zeuz Gingerbread ROM I downloaded from here but after the phone reboots all I get is "LG logo saying SECURITY ERROR"
Anyone has gone through this issue?
BTW: after the LG Security Error I have to get into S/W Upgrade and run the LG Mobile Support Tool to let it flash the stock firmware again.

The boot loader is locked. There are a number of tutorials on how to unlock it, but you need the original Froyo or Gingerbread ROM images from LG. Locating those seems to be the tough part. You downgrade to the earlier version, then you unlock.

Thanks for pointing me in the right direction

Do I really have to unlock before flashing Gingerbread?

As the title of the thread says, I read the guide to install JVK/JVA/JVB and it says that before flashing I must have my phone unlocked.
When it was only JVK in that thread, I didn't see this note so I flashed it. That was 2 weeks ago and I haven't had any issue with the Network.
I haven't unlocked my phone and I don't want to because I read the guide for unlocking and I can't use adb.
So, can I flash JVB now? Are there any issues that my phone can suffer? I asked in the thread this question but nobody answered me, so that's why I made a new thread.
I'm using a JVB based gingerbread rom without any issues and never unlocked it... In fact this is the first time I heard this...
Sent from my GT-I9000 using XDA App
Warning:
*These firmwares are for International I9000 Galaxy S version, your device must be unlocked before flashing these firmwares.
So, I'm waiting for other opinions...
AS they are unofficial firmwares i guess instruction might be for safety .
Official updates via Kies when 2.3 is released will not need unlocked phones .
jje
flash and see yourself !
I flashed a phone with no root or unlock from 2.1 to 2.3.3 works
I had a hard time trying to root 2.1 and got it boot looping so the last a tempt was a full flash of jvk work and saved the day.
I then was able to use cf-root 3.1 to get root and app from the market to unlock.
I'm ready to do it, but what issues can it cause? I heard something about a code at the first boot that you must enter but I don't know exactly.
Can I downgrade to 2.2.1 stock for example if I have problems?
Edit: I flashed JVB without having any issue. Thanks for the help anyway, I was pretty doubtful about what can happen. All the things work.
Cheers!

LG 2.2-2.3 Rooting

Hello,
I have an LG P500H that according to the settings menu is currently on Android version 2.2
I've read in countless places that this device is eligible to be upgraded to an official 2.3. Through the LG support tool a notice displays there is an available update which im assuming is the 2.3 itself.
My question is with regards to rooting. I have located a thread about rooting this device on 2.2 firmware but nothing specifying any process for 2.3. If I root on 2.2 my assumption is I will lose my root once I upgrade. How would I go about rooting this device on official 2.3 firmware.
Thanks to everyone for reading.
-------------------------------------------------------------------------------------------------------------------------------------------------
Here I will list the only post I've found referencing this involving rooting through ADB. Can anyone confirm? Or suggest a safer method to ensure success with no issues? The post is as follows:
The LG Optimus One P500 is the one of the best budget Android phones around. Now it can be updated to Android 2.3.3 Gingerbread, then the purpose of writing this article is to help you to root stock gingerbread in an easy way. LG Android Phones
How to root Android 2.3 Gingerbread on LG Optimus One P500:
1. Read everything first and after do what is necessary:
What Is ADB and How To Install It With Android SDK, please go to here.
INSTALLING ANDROID SDK ON YOUR WINDOWS PC from here)
Don’t forget to restart your PC after installations. LG Phone Problem and Solution
2. Download and install SuperOneClick. You can download the tool from here.
3. In adb:
adb devices
adb shell
echo 1 > /data/local/lge_adb.conf
After that open SuperOneClick and root using pneuter. Reboot phone and update Superuser from Market.
This instruction works fine on my LG Optimus One, I had some problems updating superuser, kept force closing, but after restart, it works. hit thanks if this was useful for you.
EDIT: So I try to update software through LG support tool. The first screen of the tool checks the software and says there is an update available. Doesn't specify what version. When the option to start the update is selected the second tool launches and says device is not able to be updated. Another question would be what exactly is going on with that? and how to go about getting the official 2.3 on this P500H. Thanks.
This is ridiculous.
I check the TELUS website which is the carrier for my device. Turns out the only "update" listed on their end is 2.2.1 and the instructions stated my device needed to upgrade as I was running 2.2
So I go ahead and update my device and everything completes as the instructions stated.
Well, now the phone is stuck in a bootloop at the android logo and will not go further. Thanks TELUS.
Edit: Hard reset fixed this issue, now running 2.2.1. Getting really fed up with this so called official 2.3 that I can not seem to get. Anyone with answers please assist.
heres the official gb rom:
http://forum.xda-developers.com/showthread.php?t=1140862
Thank you for the link. I looked over the thread and noticed that the post mentions v20g and v20c versions for download.
I'm guessing these are international versions as I have checked my phones About menu and noticed I have a software version listed as LG-P500H-v10s
How would this impact installing official 2.3 or is there anywhere I can acquire a version for my device.
Thanks
Doesn't really matter which one you use
V20c is unbranded, don't know about v20g.
Would it be correct to say that the reason I cant get this software update through the LG Support Tool or on my Canadian carriers website is because it isn't offered at this time by my specific carrier?
Therefore its been put out mainly to international carriers, hence why I would have to use an unbranded generic firmware? Just wanted to inquire so that when I complete the flash I'm fully educated as to which version I'll be using. Does anyone happen to know if NFC (near field communication) is supported in this unbranded version?
EDIT: Just to add. There appears to be a notice at the bottom of the page mentioning no 2G/3G data - wait for new release. Is this relative to the official 2.3?
So I am experiencing much lag on the 2.2.1 firmware that I am currently running ton this P500H for these reasons I will be attempting to flash to the official 2.3 in hopes of better performance.
Looking to clarify some instruction from the OFFICIAL LG GB thread listed in one of the responses. The tutorial states to flash "the russian way" and provides a HOW TO for using the LG DMP tool. In the tutorial the method says "This HOWTO is for users who want to switch from stock LG 2.3.3 ROM to CM7 or other older ROMs that are NOT based LG's on v20 ROM or vice versa"
My question with the statement is how does it impact the fact that Im on a stock 2.2.1 not flashing to a CM7 or vice versa. Which baseband would I be using as I am not sure what exactly this 2.3 is based on and I am running a v10s.
My guess is I would download the second baseband file in the thread listed as "- P500-v20G-baseband.7z is for official v20[abdg....] ROMs and ROMs based upon it (e.g., GingerLOL, v20G stock ROM, customized v20G ROM, 0x0v3rfl0w ROM and GingerCriccoROM)." and then flash the v20g 2.3 firmware.
If anyone can elaborate so that I dont brick this device when flashing
Another part of the article says "Eventually, all new ROMs will switch to new baseband by default, so it is useful as well if you want to avoid the complete KDZ/Russian way flash which wipes everything." Would this mean flashing "the russian way" with .kdz file would mean not having to change the baseband in the LGDMP tool. Kind of like an all in one solution instead of a drawn out process? I found a post with instructions for KDZ updater but dont have a file for 2.3 android to flash. What is the suggested method and steps? If anyone can clarify
Move this to General section..!!
Guess this should be in the General section and not in development..
Theres a kdz file of europe and russian version on xda.. search for it.. flash it usin kdz and you are done.. you get new baseband and then root using superoneclick.. you will lose your data.. but you can back it up using titanium backup.. flash recovery n den you are ready to use any of the new custom romz.. they perform well in quadrants.. not as much as those developed by our heroes like mik andy and all.. but for a stock rom those values are good.. i reverted back to miks cyanogenmod for itz performance.. anyway, if you want a stable, ALMOST bug free rom, go in for stock 2.3.3... there are minor bugs.. like status bar icons not alligned and stuff but you can manage with it...
works perfectly

[Q] Rooting and Updateing LG

Hi
My problem is "Waiting for device"
My LG is on version 2.2.2 and it says that there is no Upgrade available

Every time I try to Root my phone i get error "Waiting for device"
My debbugin is on, and I turned of my firewall is there something else i need to do to get Rooting Right ?

You can safely update to 2.3.4 and then root using one of these guides:

That second link for update to 2.3.4 GingerBread works 100% on my LG Optimus 2x ?
EDIT : Can i get link for updating my LG from Froyo 2.2.2 to Gingerbread 2.3.4 , safetly
It should work, follow the guide to the letter and you should have rooted your phone.
Here's your link:
http://forum.xda-developers.com/showthread.php?t=1327929
Wait
First link is for Rooting phone
Second is for update to Gingerbread
Third is for Rooting phone on Gingerbread ?
No, the first three are all for rooting
The fourth one is for updating manually to GingerBread
Ok .. soo first i Root my phone by one of that 3 links and then i update to Gingerbread (4th link) ?
The other way around
If you first root and then update, you might lose your root, so...
First update then root.
By the way: After you root, do you want a stock LG rom or a custom one...?
Explame me what that means xD
Haha ok
Stock LG rom is just the normal rom from LG you have right now but then a little improved (removed unnecessary software and apps). Normally the people who like the looks of the stock rom choose Stock-based roms.
Custom roms are roms completely different than LG. They look different and they have different apps/software. Most people out here prefer custom roms like CyanogenMod or MIUI. I prefer CyanogenMod too because it's in my opinion overall better than stock rom.
You can find these roms in the development section. The reason why I asked you this is because if you want to have a custom rom, you don't need to update to 2.3.4. You just can root 2.2 and flash one of these custom roms over it. This will automatically update your phone to GingerBread.

No I didn´t try OTA update . I bought LG 2 days ago soo kinda new here xD
Try one first,
go to settings ----> about phone ----> phone version (or something like that, not sure) and do the update from there. Trust me, this is much easier than the kdz method. If there is no OTA, then you should use the kdz method.

Well i did this metod to root my phone http://forum.xda-developers.com/showthread.php?t=953182
But how i can be sure that my phone is Rooted successfully ?
There are a lot of ways to check that. You can either look in your app list for an app called Superuser. If you have this app then you should have rooted successfully. But if you want to be 100% sure, download the root checker app and see for yourself .
Hey guys,
I just rooted my phone yesterday on stock 2.3.4 and got this annoying issue: Every time I shut down and restart my phone, some settings revert to default on their own. For instance, text input language becomes german (was the default language when I bought the phone), input text sounds are activated again, and so are mobile networks which I must disable quickly because they mean charges.
Could you please shed some light here? Thanks!

AFAIK, this is the only way... Because you have no OTA it seems that this is the only option. But I'm not sure about that.
My advice is to search, perhaps there is an easier way to do so.
EDIT: Download Rom Manager (app) and from there install ClockworkMod Recovery. With recovery you can flash a stock-based gingerbread rom on your phone! (how could I not think of that earlier ) make sure to do a nandroid backup in recovery mode.
EDIT 2: You might wanna try this: http://forum.xda-developers.com/showthread.php?t=1408919
Flash this in recovery mode.
Or you can just go directly to the latest KANG-54 build. Android 2.3.7, very stable and smooth as butter.

[Q] Invalid software package when trying to update my phone

Hi guys!
I noticed today that there were a system update for my optimus 2x.
But after it downloaded it said validating software package and returned an error stating that the package was invalid..
Has anyone else bumped into this problem? Is it because my phone is rooted?
It is otherwise stock.
Thank you so much for your help!

Okay.
So can i ask how do i unroot the phone using CWM?
I looked at this thread: http://forum.xda-developers.com/showthread.php?t=1021554&page=2
it talks about installing a recovery.zip using CWM, but will it unroot the phone or not?
Thanks!

Hi and thanks for the answer!
you see, my phone is already rooted. I need to unroot it in order to get the latest update from LG installed on my phone.
The reason for this is that when i download the update OTA and try to install it, i get an error message stating that i have a invalid software package.
And the reason for this as i understand, is that the phone is rooted.
i have read the roll up thread you linked to, but it does not state anywhere how to unroot the phone. And thats what i need help to do
Use smartflash and put some older version on it, then update it to current version. It will be unrooted.
Thank you for the answer, will try that!
But im struggling a bit to find the older versions though. The links to them are either down or broken. I need the EUR version.
You can flash stock v20q via cwm. If you said that your phone is rooted, install cwm and then flash this stock v20q.
If you want to downgrade, then update using lg update tool, you need smartflash and some older firmware like Euro v10d.
You need to read and search, really, all is here on the site.
At least press the thanks button if my posts are helping you, it is right here.
Thank you for the reply.
I will flash with the v20q one you mentioned. Its the version im trying to upgrade to anyway, så this seems better instead of downgrading it to stock, then upgrading using OTA!

Rooted with motochopper and cannot do firmware update

I've tried uninstalling superuser and all it has. I've tried like 5 times now the install for the new firmware update won't install i keep getting a android with the red exclamation sign and its front door open, then it boots in to android and says update failed. Help please!

Hi buddy.
First of all, I don't entirely understand what are you trying to do. What to you mean with "firmware update"? Do you want to flash a new ROM?

Sadly no, my friend. Any reason in particular about why you want this specific update?
Let's hope somebody else in this forum can help you.
Are you running a stock recovery? Have you tried using Myth Tools to flash back to stock?
Its running stock rom from factory everything is factory right now
I kept getting the dead Android as well. We're you running a KK ROM on your phone before restoring to stock? I was running Validus and tried to use Myth Tools to flash a stock ATT 4.1.1 ROM which also failed to take the update. I then installed a 4.1.2 Bell stock ROM (my phone came from Bell) via Myth, let the phone boot, and then flashed a stock ATT ROM via Myth and it took the update.

I am on 4.1.1 from the factory. This is a referb phone from the factory like not even a week old yet. Boot loader isn't even unlocked. Its all stock and I'm getting dead android.
If you're getting the dead Android, it makes me believe that something may be wrong with the stock recovery. Some people were able to get the update to install using the latest Philz Touch recovery rather than stock recovery.
