Wanna make your own rooted software? It's quite simple, due to navossoc! Thanks for this guide and the tool. [TOOL] Lg Extract Tool
Follow the guide, and first extract the kdz file into a cab file. Extract this cab file, then you ll get a v00y.wbd file and a LGP970.dll. 00 represents your SW version, e.g. 10 or 20 and y stands for a letter like B,N,...
So you e.g. get a file called v20N.wdb file.
Then again open the programm in cmd and extract the wdb file (see in the link above). Be sure it is in the same folder as the lgextract.exe file, or add the patch of the file. Copying it to the same folder is the easier solution
Now you ll get a new folder and in it a few bin files and one fls file.
First cd ti the new bin folder.
You need to add up all the files with this command:
copy /b "LGP970_AP
[*].bin" "LGP970_AP.bin"
Now you have a flashable bin and fls file for Smartflashtool.
If you wanna root it, you need Ubuntu or another linux distribution, which supports the dd command.
Then follow THIS
It's really easy, so dont ask for rooted software anymore, but make it on your own.
To flash and actually root the SW, you need to follow THIS guide, from Step 2 on, and it will be perfectly rooted and you can be sure, that noone patched anything else in your software, cause you made it on your own
Now you can link to this post directly, if anyone is asking for ANY rooted version
There already is an updated tool, which does the unpacking and injecting CWM automatically. I am sorry, but I dont have time, to update the post, so here is the link: http://xdaforums.com/showthread.php?t=1692191
Catching a logcat:
Whenever you QQ (cry) around because anything doesnt work, every dev can only guess, what s your problem. If you wanna provide the necessary information to him, give him a logcat and he will be happy and fix the bug you are getting.
Ricardo Cerqueira once posted this pic about this topic
So here is what you need to do, before you report the next bug/error to your dev.
1. Download QtADB from HERE (Find their HP here: http://qtadb.wordpress.com/)
2. Extract it to some place you wanna have it.
3. Now Open QtADB.exe
4. Connect your phone in debug mode
5. Click logcat on the left side (it's the last one)
6. Now Reproduce the problem, that you have, like force closes or other stuff.
7. Maybe reproduce it a second time
8. Push ctrl+A to mark all the lines
9. Right click it and choose, export selected to file
10. Save it to a place, where you can refind it.
11. Upload it somewhere (e.g. mediafire.com)
12. Post in the corresponding thread and give them a description of the error, so they know, what they need to look for and the link to the uploaded logcat.
This will improve a lot of ROMs around here, cause everyone uses it, but hardly anyone (including myself) can contribute to cooking/deving. So do us all the favour, that if you experiance an error and it's cause by the ROM and not a buggy installation, make a logcat and post it to the threads of the devs
Here is how it typically looks (Zeus ROM v4.02 + LG kernel without dimming light):
This is going to be a big NOOB how to, since I read the same questions OVER AND OVER again! If anyone then asks a question, that is already answered here, just redirect them here and close/delete their thread.
I am sorry for not having updated this in a long time, but there is simply stuff, that seems more important to me, than Android

OTA: Over The Air, Update via Wifi/network, I suggest you not do use it. FC: Force Close, error with apps, which forces them to be closed. chmod: Set permissions to a file. E.g. make it read/writeable.
Lets start with ROMs/kernels:
ROM is practicly the whole Operating System of your android device. It includes all software needed, plus a kernel.
Then there are kernels, which mostly tweak some stuff, in order to save battery, provide more speed, provide stuff like OC(overlocking) and UV(undervolting).
A modified kernel is not a whole ROM! It only is additionally to a ROM, in order to tweak it
A kernel is the HEART of a ROM. (Thanks to gabwerkz) Also see here: Kernel
AVAILABLE ROMs:
There are several ROMs: Stock Roms:
Froyo (Android 2.2.x) (V10x)
Gingerbread (GB) (Android 2.3.x) (v20x)
Ice Cream Sandwich (ICS) (Android 4.0) Not yet officially available for our device yet.
Cause this gives you something like admin privileges in windows.
This allows you to modify/add, delete,... files, that ususally are protected.
It also allows you to install ClockWorkMod, which in turn allows you to flash custom ROMs, which we all like so much, because of their smoothness, battery saving possibilities, OCing, UVing, and so on
ROOT ON Froyo (2.2.x, v10x)
For the v10x Versions (Froyo, Android 2.2.x), BlackJack should work in most cases, find it here: [STARTER] Upgrade Kit 3.6 | Apps 1.9 | Root, Flash, Unbrick, Tuts...
Also find a CWM installer in this package, or download ROM Manager from android market and install CWM (ClockWorkMod) from there.
CWM gives you the possibility, to boot to a special kind of OS, that allows you to delete data, mount system, data,... And most important flash .zip files.
If a version cant be rooted by using Blackjack, try SOC (SuperOneClick).
If this still doesnt work, leave a comment, of your version and a link or description, of how to root it.
You also might wanna try UnlockRoot.
To flash and actually root the SW, you need to follow THIS guide, from Step 2 on, and it will be perfectly rooted and you can be sure, that noone patched anything else in your software, cause you made it on your own
There already is an updated tool, which does the unpacking and injecting CWM automatically. I am sorry, but I dont have time, to update the post, so here is the link: http://xdaforums.com/showthread.php?t=1692191
It's really simple. Download: THANKS TO ILKO for the clean installer.
Install, run, reboot your phone and your done
Please do not try to install CWM on ICS. You'll get a security error and will have to unbrick your device!
If you already have ICS stock on your phone, there is a simply procedure, that will allow you to get CWM again, but you'll have to install a new ROM via Smartflashtool.
1. You need a V20 ROM, that has been patched with CWM, like THIS ONE.
2. You need Smartflashtool
3. Download Superuser.zip from here: http://downloads.noshufou.netdna-cdn.com/superuser/Superuser-3.1.3-arm-signed.zip and put it on your SD card.
4. Unpack the V20S patched .7z file
5. Flash the .bin file using SFT
6. Your phone will reboot to recovery
7. Do a factory reset and if you wanna stick with a rooted v20S, just flash the superuser.zip and reboot. If you already want to install a custom ROM, just put that on your sd card and flash it (see how to install a custom ROM).
8. Reboot and enjoy your new ROM
The UNROOT
If you wanna unroot your device, why so ever, the easiest way is to use Unlock Root (Link above) open it, connect your phone via USB, enable Debugging Mode and click unroot. If you wanna unroot it, e.g. to be able to send it back to LG on warranty, better use the method below, to unbrick your device with R&D tool.
Because like this, you will get back an unrooted device, which has also been hardresetted. So LG will hardly/never get a clue, that it has ever been rooted.
Dont forget to format your SD card as well
How to install Custom ROM's
First of all, you need a rooted phone already. See above, how to do it
Then you need to install CWM (Clock Work Mod), you can do this e.g. by downloading ROM Manager, install it, open it
and find Install Clockwork Mod Recovery. Hit it, wait some seconds and click LGE optimus Black. Wait again, till the file has been downloaded and installed and your all set Now you can reboot into Recovery, with the second option. It says, what it does: Reboot to recovery
Now grab the ROM you desire the most and download the zip. Plug your phone to the PC (via USB) open up the folder of your SD card, and copy the file you downloaded in there. Dont copy it into a subfolder, since it will only be harder to find.
Now go back to ROM Manager and click reboot recovery, or if you have adb installed, just type reboot recovery in a terminal on your pc.
You are in recovery menu now.
First of all do a nandroid backup (explained on top). To do so, go to Backup and Restore, then Backup and wait.
It will now make a complete backup of the whole system, settings, and so on.
If something goes wrong during the installation of the new ROM, you can simply revert back to the state you had before.
Your ready to install the new ROM now.
Now it depends, on if you only update a ROM, like CM, or if you install a completely new ROM.
If you install a new ROM, do a full wipe. This means, wipe data/factory reset, wipe cache, go to advanced, wipe dalvik, wipe battery stats and go back. now select install zip from SD card. Then choose zip from sdcard and then select the file you downloaded.
Wait till all is set up and enjoy your new ROM
If you only update a ROM, follow the instructions given in the thread about the ROM.
What to do if the Update failed?
Well it depends on how much you failed, what u had installed before and if Huexxx Recovery fix was applied.
First scenario: Huexxx's patch was applied in the ROM before.
This enables to boot to recovery by repeatedly pushing a hard key, like volume- or g-key directly after you start the phone.
Push em fast, while the softkeys are flashing(turn on and off). As soon as they stop flashing, you will be in recovery and can either restore a backup, or install another zip file.
Second scenario:
CWM is still enterable via adb.
You first of all need to download and "install" ADB.
Best will be, to simply extract the files to C: and also rename the new folder to a short term like "ADB" without "".
Then open the command prompt, navigate to the folder of adb: e.g.
Code:
C:
cd ADB
cd adb
Now you should be in the adb folder, where you can find adb.exe and some other files.
If not, check out, how it is called and navigate there in another way.
"cd" means change directory, so if you didnt rename it to ADB, but e.g. ADB-sdk, type cd ADB-sdk instead.
Ok, now simply type adb reboot recovery and wait.
Now your phone should restart to Recovery Mode.
But watch out, if you do this with a working ROM, and forgot to install CWM, you will get a factory reset!
Third scenario:
None of the above worked. Then you have no chance, but to to use the unbricking method below. Then root your device, install CWM and you can have a new try
Your Phone doesnt boot anmore or only shows the LG screen contantly!
If your phone is stuck in bootloop, have a look in here: SMARTFLASHTOOL
You can download the patched V20s from ABOVE or take the v10a from here
Flash with R&D Tool:
The upper is the easier and faster solution, but if you really need R&D Testtool, because Smartflash didnt help, grab R&D tool HERE(it's in the package), and then follow THIS guide
You can also use the latter method, if you wanna return your phone on warranty. But I would make a Factory reset afterwards anyway. And don't forget to remove all files from your SD card as well, since this could show them as well, that the phone might have been rooted.
Themes are modifications to the look of your UI (UserInterface). This gives your Operating System a different Look.
There are a lot of things, you need to pay attention to.
For example there are ODEXED = easier on space, tougher on tweaking and ram usage (just a short explanation)
and Deodexed = easier to tweak, lighter on ram, heavier on space
Find more information on this HERE
Now you need to know, if your ROM is odexed, or deodexed. You mostly find information on this directly in the thread of the ROM you are using (see above).
If you know what kind of ROM you are using, go to the Themes link above and choose whatever you like. There is almost always written, for which specific ROM this was made (e.g. Zeus ROM, Stock GB, stock Froyo,...) And mostly, if you need a odexed or deodexed Version of a ROM, or not.
It's pretty much like odexed files also work on deodexed Software, but not the other way around. (NOT ALWAYS)
Then you encounter bugs like missing statusbar, display bugs, glitches, ...
So check if the theme you are willing to try will REALLY work for your device.
If you wanna make your own Themes, check out UOT KITCHEN Or these two threads: HERE AND HERE Credits to gabwerkz and Huexxx.
More to come, leave comments with topics, I am supposed to add, or critics
To come
Whatever you want me to post here
Couldnt find what you were looking for? Did you already use the search in upper right corner?
If not, go to Q&A section and post your questions there pls.
Only post here, if I am supposed to add something, or explain it a better way
Can you tell me, why anyone with a rooted phone would want it? I mean, sending it back to the provider for repair or similar is a reason, I can understand, but what are other reasons? Idk if it's enough to flash it with smartflash and afterward go to hidden menu and do a factory reset, but I guess this should work fine
Any suggestions on this? Or maybe the R&D tool and workaround?
The means to unroot isn't in the first post, and the OP is discussing this issue with him so - don't post unnecessary chides, it is a legitimate question, posted before I warned that this isn't a Q&A thread. Hopefully the answer will be included in the OP, as it is something that will be asked - over and over again .
You have helped me out quite a few times earlier and now I thank you for the "real thing": being generous enough to go through the trouble of making things easier to everyone else. That takes patience and a really good deal of generosity. And maturity above everything else.
When I began working with IT by 1981 I was nice to my peers. Then I became more and more technical and efficient at my job, and harder and harder at my peers and everyone else.
In return (despite all my capacity) I only drew drawbacks. My career sank. I had to start it all over again, with a different drive. ;-)
Today IT is just a hobby, and it's encouraging to see that at least a few of the most gifted people are showing that gift and contempt are not always bound to each other! :-D
Attitudes like yours, although they don't warrant you (1) a $300K/Y job, they DO warrant you (2) a very, very nice feeling that is hard to describe (albeit I suspect that you already know it) and (3) raise the suspicion that there's really a God and that (4) we are really above the rest of the animal kinds. I hope you get all four.
Congratulations and just forgive me for the last kitsch words

Thank you very much, for such an encouraging post I like and appreciate it very much. But there is one thing, that I can't stop wondering about, how could I help you out already? I mean you should probably know more bout IT and programming and stuff than me... Just curious Anyway, I like to help ppl out a lot. I also do this in real life a lot, but the problem is, that a lot of ppl dont pay you back at all. Just using one's knowledge/money/whatever and not giving back anything, or even ignoring advices and stuff is something I hate the most! Just like some of the Noobs here. I have nothing against questions and there never will be a stupid one, so dont stop asking, it is an important part in life. But I hate the ignorant noobs, that dont even try to use the search, dont look around in the forum, are simply too lazy, to look around but simply create their own threads, with questions, or information, that can already be found here. And mostly you can't only find it once, but already several times, because of them.
So dont stop asking, but use search first, pls... I'm also still a noob, so I also gotta ask a lot of questions, and this will never stop, until I either throw away all the IT around me, a solar storm makes it impossible for us to use any kind of IT, or I am dead
So to all the others here, share your knowledge with the ones, who also would like to have it. I also know, that it is time consuming, but trust me, giving, will mostly/always be warranted in any way later. I believe in karma and who gives good, will receive good. So maybe one day, when you dont have time/dont wanna mod anymore, but still wanna use good modded software, you need someone else to do it for you and who could do this better, but a person, that learned from you? So I never will stop supporting this community as long, as I got some time.
And I also know, I was writing a lot now and better stop now
Just one last thing, keep me posted, if we need some information added, so it can be found more easily, as long as it can be explained in a way, even I will understand

I know a lot of old-school stuff that is still valid, but when it comes to Android I'm a complete moron. Got my OB by Oct 2011 and I'm still trying to leave the craddle. BTW this OB is my first SP, and I wanted to take the most out of it.
Yes I need help, and XDA is BY FAR the best Android site I've seen in the net.

For some time I used to post frequently at ABXZone (used to be a more populated community) under the same nickname and believed EXACTLY the same thing. I don't post so often these days, since my kids keep me busy enough. But as I said, when it comes to Android phones I'm still a complete moron, so in some way I'm being paid back here for that I did there.
And I also know, I was writing a lot now and better stop now
Just one last thing, keep me posted, if we need some information added, so it can be found more easily, as long as it can be explained in a way, even I will understand
And where do I get it from? PM the original poster of the topic pls ;-)
-edit-
Ask Huexxx either in a PM, or simply in his thread, since I am sure, he still has got it somewhere on his PC
Or anyone else might mirror it.
Read the first post carefully and you will already find the link to gabwerkz and another theming guide and about making bootanimations, is nothing for a noob guide. This is meant to help ppl who start out with android. Not list every single topic in here I think this is a bit too advanced for noobs. And as soon, as anyone is a bit into the whole android thing, he will know, where to search for and find sources of knowledge, he/she is willing to get But thanks anyway, maybe I'll add it to the second or third post

If you install a new ROM, do a full wipe. This means, wipe data/factory reset, wipe cache, go to advanced, wipe dalvik, wipe battery stats and go back. now select install zip from SD card. Then choose zip from sdcard and then select the file you downloaded.
Wait till all is set up and enjoy your new ROM
If you only update a ROM, follow the instructions given in the thread about the ROM.
What to do if the Update failed?
Well it depends on how much you failed, what u had installed before and if Huexxx Recovery fix was applied.
First scenario: Huexxx's patch was applied in the ROM before.
This enables to boot to recovery by repeatedly pushing a hard key, like volume- or g-key directly after you start the phone.
Push em fast, while the softkeys are flashing(turn on and off). As soon as they stop flashing, you will be in recovery and can either restore a backup, or install another zip file.
Second scenario:
CWM is still enterable via adb.
You first of all need to download and "install" ADB.
Best will be, to simply extract the files to C: and also rename the new folder to a short term like "ADB" without "".
Then open the command prompt, navigate to the folder of adb: e.g.
Code:
C:
cd ADB
cd adb
Now you should be in the adb folder, where you can find adb.exe and some other files.
If not, check out, how it is called and navigate there in another way.
"cd" means change directory, so if you didnt rename it to ADB, but e.g. ADB-sdk, type cd ADB-sdk instead.
Ok, now simply type adb reboot recovery and wait.
Now your phone should restart to Recovery Mode.
But watch out, if you do this with a working ROM, and forgot to install CWM, you will get a factory reset!
Third scenario:
None of the above worked. Then you have no chance, but to to use the unbricking method below. Then root your device, install CWM and you can have a new try
Your Phone doesnt boot anmore or only shows the LG screen contantly!
If your phone is stuck in bootloop, have a look in here: SMARTFLASHTOOL
You can download the patched V20s from ABOVE or take the v10a from here
Flash with R&D Tool:
The upper is the easier and faster solution, but if you really need R&D Testtool, because Smartflash didnt help, grab R&D tool HERE(it's in the package), and then follow THIS guide
You can also use the latter method, if you wanna return your phone on warranty. But I would make a Factory reset afterwards anyway. And don't forget to remove all files from your SD card as well, since this could show them as well, that the phone might have been rooted.
Themes are modifications to the look of your UI (UserInterface). This gives your Operating System a different Look.
There are a lot of things, you need to pay attention to.
For example there are ODEXED = easier on space, tougher on tweaking and ram usage (just a short explanation)
and Deodexed = easier to tweak, lighter on ram, heavier on space
Find more information on this HERE
Now you need to know, if your ROM is odexed, or deodexed. You mostly find information on this directly in the thread of the ROM you are using (see above).
If you know what kind of ROM you are using, go to the Themes link above and choose whatever you like. There is almost always written, for which specific ROM this was made (e.g. Zeus ROM, Stock GB, stock Froyo,...) And mostly, if you need a odexed or deodexed Version of a ROM, or not.
It's pretty much like odexed files also work on deodexed Software, but not the other way around. (NOT ALWAYS)
Then you encounter bugs like missing statusbar, display bugs, glitches, ...
So check if the theme you are willing to try will REALLY work for your device.
If you wanna make your own Themes, check out UOT KITCHEN Or these two threads: HERE AND HERE Credits to gabwerkz and Huexxx.
More to come, leave comments with topics, I am supposed to add, or critics
To come
Whatever you want me to post here
Couldnt find what you were looking for? Did you already use the search in upper right corner?
If not, go to Q&A section and post your questions there pls.
Only post here, if I am supposed to add something, or explain it a better way
Catching a logcat:
Whenever you QQ (cry) around because anything doesnt work, every dev can only guess, what s your problem. If you wanna provide the necessary information to him, give him a logcat and he will be happy and fix the bug you are getting.
Ricardo Cerqueira once posted this pic about this topic
So here is what you need to do, before you report the next bug/error to your dev.
1. Download QtADB from HERE (Find their HP here: http://qtadb.wordpress.com/)
2. Extract it to some place you wanna have it.
3. Now Open QtADB.exe
4. Connect your phone in debug mode
5. Click logcat on the left side (it's the last one)
6. Now Reproduce the problem, that you have, like force closes or other stuff.
7. Maybe reproduce it a second time
8. Push ctrl+A to mark all the lines
9. Right click it and choose, export selected to file
10. Save it to a place, where you can refind it.
11. Upload it somewhere (e.g. mediafire.com)
12. Post in the corresponding thread and give them a description of the error, so they know, what they need to look for and the link to the uploaded logcat.
This will improve a lot of ROMs around here, cause everyone uses it, but hardly anyone (including myself) can contribute to cooking/deving. So do us all the favour, that if you experiance an error and it's cause by the ROM and not a buggy installation, make a logcat and post it to the threads of the devs
Here is how it typically looks (Zeus ROM v4.02 + LG kernel without dimming light):
