Root
Download the zip-Superuser-3.1.3-arm-signed.zip- from here: http://androidsu.com/superuser/
And then flash it in recovery
It worked for me

any chance of getting rooted without flashing bootloaders or whatever? just like in the old times with superoneclick or megatron?

Flash the prerooted rom

untill the V28b, i was still afraid to flash the bootloader, 'cause someone said that would make the phone lag. i only use the prerooted rom in xbsaV7,V8 thread to get root.
but recently i flash the bootloader to get root in the official v30a to find out if it would get lag or not! well,after a few days test, the answer is no! it won't get lag issue.
after rooted the rom , i flash back the LG official bootloader, the phone still be rooted. so i recommend u just flash the bl it wont hurt your phone.~O(∩o∩)O~

Question about flash from a (maybe) future O3D owner

Hello, maybe i'm going to buy an Optimus 3D soon.
I've got some doubts about the flashing process: on Android i'm used to flash with ClockWork Mod Recovery, but i see that there you use another method that needs Windows on a PC.
How's that? Can i choose which one to use or do I really need the program on my PC?
And also the modified USB cable?
We still use Clockwork Mod Recovery.

cwm as usual to flash firmware in zip format... u only need the lg update tool if you want to flash kdz files which are basically the form in which lg releases the firmwares.

Ok that's great, so for custom ROMs i won't need it
And what about flashing CWR? Is it Root>Flash from terminal?
Ok i should get it tomorrow (can't wait )
I've seen that to flash a radio i have to use the LG Flash Tool, right? I'm talking about this: http://forum.xda-developers.com/showthread.php?t=1244490
And i have to change radio to switch to Gingerbread. Do I just need apps on my computer or also the modified cable?

no need for modified cable but seeing as many people still cant make gb to work on their phone i would wait 2 more weeks for official gb update and then having the gb baseband start messing with custom roms...

Right, i think ROM manager is easier, even if it should work also with ADB terminal
So official Gingerbread will be released in 2 weeks? :O
To get official updates i can't root and flash CWM?

you can but then it is better to update through zip files in recovery than trying lg update tool cause some people have problems updating through lg update tool after they have rooted and cwm. I never had any problem though. my phone is rooted from day one and has cwm and still getting updates through lg update tool...
But will we be able to flash the radio from a ZIP?
No. CWM do not flashing Baseband.

Yes i got it, my question is if this process would still work with a rooted custom ROM and CWM installed instead of the default recovery.
Yes, all who have GB now have root and CWM installed and they flashing basebands

First upgrade to official gb will have to be through either lg update program or by installing a kdz file of it when it is released. After that you will have the gb baseband already installed and you will be able to upgrade through zips

Ok perfect, but finally, to get official GB should i keep the original sistem or not?
And if yes, the problem will be still present with ICS, right?

[Q] V21Y update

So did a restore to stock V21e. Did the ota update and it found it. Phone downloaded the update and rebooted into CWM?
Did a restart and Phone stayed on V21e.
Do I need to remove CWM as well?
You need to be on stock recovery since it uses it to install the ota that way (I'd assume).
http://forum.xda-developers.com/showthread.php?t=1248644
Worked perfectly for me.
What happens if you choose "install update.zip"? Isn't that how OTA updates work?

Yes, after trying all kinds of stuff to get it updated I checked the LG tool again and it found the update. Guess LG took it off.

Had a hard time removing cwm. Using LG Update it will replace it with the stock recovery and update the baseband.
Put cwm back on and you can flash it with a rooted 2.3.4

[Q] Downgrade from 4.2.2

If got the update and 4.2.2 is terrible. So I would like to know how to downgrade back to 4.1.1. There probably is a way to do it through Odin (which would be preferred) and if there is, can you give me the links to the downloads.

Did you try a wipe data/cache in recovery mode? This should help a lot, after I did the new 4.2.2 is not so bad, is at least "good" ad the 4.1.2.

No root before flashing. But if you flash the stock rom via Odin, you will need to root it again.
If you can find a flashable zip, then yes, you can use a recovery.
But OP simply wants to return to stock 4.1.1. You can get back to complete stock setup with the Odin process.
Search online for exact procedures.

After rooting your phone with kingo.. what happens.? Does it say rooted successfully or you get any error?
If it says rooted successfully then install supersu from play store, it should work
Or try rooting your phone using framaroot

just do a factory reset
And after that try rooting your phone
(I always factory reset my phone whenever I am having problems with it. That's why I suggest it to many users )
PS: I m not 100% sure if it will work or not but you can give it a try
=> which exploit u used to root using framaroot? Gandalf works for Samsung

No it will not downgrade your phone.. it only restores settings.
If you want to downgrade your phone, you will have to root it and then have to flash strck firmware

No need of root to downgrade! Just download the previous firmware version from sammobile.com and flash it with ODIN.

Hmmmm you don't need root access to flash using odin (I came to know about it just now thanks to @sanjay.addya )
So you can just download the old stock firmware and flash it properly using odin.

[Guide][Receive OTA after root][keep apps/data][GT-I9500][5.0.1]

a lot of users are having this problem and if you want to receive an OTA you have to flash the stock unrooted firmware that will cause lose of data.
this guide will show you how to receive OTA again without losing your stuff
This works on GT-I9500 ONLY! (Lollipop 5.0.1 Recovery)
This also should work on any other model, but you have to replace the recovery with your model!
Steps:
1- Go to SuperSU and scroll down to "Full unroot" then reboot.
2- Download This file to PC and extract it.
3- Go to download mode by pressing the power key + home key + volume down key at the same time, then press volume up.
4- Flash the file via Odin (AP) or (PDA)
go to check the system status, you will find it Official
you can now receive OTA.
Q&A:
What is OTA (Over The Air)? Its an update which you can receive over wifi or mobile data.
What do i get from OTA? Well, if you root your device you wont be able to receive an update again, unless from flashing firmware via Odin.
- Why im still on custom status? Because you modified your system.
- What kind of modifying? Installing busybox, editing or deleting or changing any app or file system.
and some times xposed.
- How do i restore the old app? You can restore them by flashing firmware or by restoring Nandroid backup.
- Then what is the use of your guide? Well my guide helps in first place the rooted not the modded onces.
and always do Nandroid of the original system apps+data
you are still having your apps, data, pics, vids, etc...
you can root again at anytime.
check my thread for rooting if you want

Hi there,
Thanks for the guide, just thinking you may want to say what option in Odin to put the file and what OTA stands for, for the noobs.
Just a thought.

At some point the update maybe canceled, because the update checks for the apps before the installation, always do a backup of your phone then remove what you want, after you want to update just restore the system folder from the backup
