Since nobody else has answered in 24 hours, I will, although carriers here in Greece do not lock their phones and so my knowledge may not be accurate.

1. AFAIK, once you unlock a phone, it stays unlocked even if you root, reset or flash a new ROM. So, you won't have to enter a new code. I hope somebody who has done it can confirm this.

2. Yes, once you root, you can do whatever you want. Remove System apps, convert User apps to System etc. Just be careful and make a backup of your ROM in recovery before you start tweaking it.

You are not supposed to flash the firmware through OMAP boot, so you don't need those drivers. Please make sure you have read the OP thoroughly and that you are entering S/W download mode the way I describe.

[LG Optimus 3D] Goston1984:
Yep. The situation is the same. Is it necessary to use LG's sh.. to flash the kdz? I have win Xp, so I assume I might use the KDZ_FW_UPD soft instead. But I am not certain.

Thx
[LG Optimus 3D] dreccon:
That's right, you can use KDZ_FW_UPD on XP and you don't need the LG tool. It's extremely easy to use. Just install the driver, open the tool, select your KDZ, select CS Emergency, connect your phone in Download Mode and press start. Don't worry if the tool looks frozen at first, it does that while unpacking the KDZ. Just let it work.
[LG Optimus 3D] Goston1984:
Thank you very much! I managed to flash the new KDZ in no time... But I still have the issues that made me flashing the ICS. I thought it would solve my problems (camera and browser are crashing, mostly when a SD card is inserted. SD card writing cause massive crash, only reboot helps. And the most annoying stuff is that people cannot hear me speaking after the approx. third phonecall. I can hear them, but they hear nothing. Reboot fixes this issue as well.)

After flashing, the internal SD had been left untouched, so I still hope that this is caused by some kind of software error.

Do you think, that formatting the internal SD and the system... and everything else should help?

Hmmm... maybe this is for another thread, but you seem to be the wizzard of this phone, so I could use your help. :)

Thanks anyway!
[LG Optimus 3D] dreccon:
Oh, no! I'm no wizard. Just an advanced user who learned a few things from the REAL wizards around here.

Well, first of all you didn't tell me which kdz you flashed. The kdz method is the most reliable way to flash official LG firmware. That doesn't mean that LG firmware is flawless. On the contrary. Very few updates were without problems. After having tried almost every firmware for this phone, I still believe v21e was the most reliable and had the least issues. If you don't mind going back to Gingerbread, you can flash that. Perhaps on top of it you might want to flash the "Promethius" ROM (yes it's misspelt but that's how Samno called it). By the way Samno is one of the true wizards. I would also recommend to watch out for Nameless ROM developed by Troopii (another true wizard) which you might dual-boot with your main ROM. It is still work-in-progress but it is quite stable already.

As for your other question, yes backing up and reformatting your internal storage could help. It is also recommended to do a factory reset after flashing, especially if you have problems on ICS. For the factory reset, boot into recovery using the key combination and reset from there. Don't do it from the Android Settings menu if you have a custom recovery or you will get stuck in a recovery loop.

New root method

BAIDU EASY ROOT APK (any ROM - Easiest way)

Make sure you have USB Debugging and Unknown Sources enabled.

Turn off all Internet communications (mobile data and WiFi).

Attached at the end of first post you will find the app. Just install it as a normal apk and run it. If you forgot to turn off Internet, it will ask you to upgrade. Don't let it, because the newer version will be in Chinese! Sometimes, the app may exit after you refuse to update, so be quick to hit the "root'' button before it asks.

In about a minute you will have root access. I would then recommend you to go to PlayStore and install SuperSu, run it and let it replace the su binary.

After that, you can uninstall Baidu root.

MEDIA SCANNER BUG POSSIBLY SOLVED!

I wonder, is there anybody still watching this thread? I have some interesting news regarding stock ICS and all custom ROMs based on it. One of the most significant bugs those ROMs have is their Media Scanner.

XDA developer [MENTION=3542212]thomashofmann[/MENTION] has made an Xposed module that gains full control over the native Media Scanner and hopefully will solve the bugs. The module was originally built for Jelly Bean and up, but now the developer has uploaded a new experimental version (1.4.0) that attempts compatibility as backwards as Gingerbread.

After my O3D died, I bought a second hand Galaxy S4 which I still have as a backup device and it's currently running on Android 8.1.

About one month ago I found a Leagoo S8 pro on eBay for only 174€!!! It is a remarkable device with a 5.99inch display, 18:9 ratio, MTK Helio P25 SOC with 2.6GHZ max frequency, 6GB RAM and 64GB ROM. It is running on Android 7.1. I have also found a port of the Google camera with Portrait mode and I must say I have shot some pretty stunning photos with it. Although I haven't been using it for very long, I'm very satisfied with it's performance. It never lags, it never hangs and it's always snappy.

Hey dreccon hows things going?

Even tho your o3d dead do you still have it?

If you do, try laying it in a container of rice. It draws all the wetness out, even if it happened a long time ago
[LG Optimus 3D] dreccon:
Hi shaqfu, yes I know the trick but I've heard it works in a different way. You put your phone in a bowl of rice and leave it there for several days. Rice (as we all know) attracts little Asians who eventually fix your device as you sleep!!!

Seriously now, my O3D didn't just drop in water. I estimate it was left soaking for about two hours. When I found it, the badly swollen battery had pushed the back cover open and the screen was like a fish tank! I tried to dry it but it was obviously badly shorted.

Anyway, I wouldn't bother fixing it anymore, even if I could. Tech has advanced a lot since our O3D was designed. It was a huge mistake by LG to only give it 512MB of RAM. Now that I'm multitasking with 6GB (for so little money), I can hardly imagine going back to 512MB!

How about you, my friend? Did you try building that Oreo for low RAM devices?

Re: [GUIDE]Installation Instructions for Official beta ICS v28b

I think you are referring to tomce5's post (which is the subject of another thread) because the tool in my guide doesn't even work on 7.

To escape from the loop, you need to reflash the kdz. Do not do a factory reset from the menu unless you have the stock recovery. When you are all set again, turn phone off, hold vol-down and press power for 3-4 sec and release (but keep vol-down pressed). This must take you to recovery. If not, then do the same but this time also keep the 3D button pressed. You will be presented with a menu where recovery is selected and the phone will reboot in a few sec. Release the 3D button but keep vol-down pressed. This time you should boot into recovery.

Out of curiosity, which recovery did you install the first time? GB, or ICS?

I don't know about Brazil. In theory, it should work. If you want to try, make a backup of your current ROM and make sure you also have the kdz file. If v28b doesn't work for you, then reinstall your current kdz, root it install recovery and restore your backup.

well you can always download the script that does all that automared and at the end even reverts back to the previous state. the only difference then on win7 as opposed to xp is one more double click on the script to execute it and one maybe one and a half seconds waiting the script to execute.

The silver logo is normal. It's the bootloader.

About the restart, all I can think of is if you have installed a custom kernel, otherwise I don't know.
