Which method do you think is much easier to get 100% SUCCESS on ROOT

after backreading for a couple of days, i have seen a lot ways to root & install recovery on our OptimusBlack .. . mine is V20B im knowledgeable enough about modding phones.. last two are OptimusOne(frroyo) & X8(eclair) ~
this one http://forum.xda-developers.com/showthread.php?t=1456274
or this one using BlackJack Method http://forum.xda-developers.com/showthread.php?t=1111771
now my question is which method do you think is much easier to get 100% SUCCESS on ROOT
someone here who get a successfull root access using BlackJack?
any feedbakcs?

IMHO, if you still om froyo, the first one should work best (SoC right?)
But GB? Try this http://forum.xda-developers.com/showthread.php?p=23790405

Question: Does this method of rooting your Black leave the Phone untouched?
Cause my mobo died on me - and after the repair i got it back from maintenance with Stock V20N on it. I flashed then V20C, rooted it with SOC and put my Nadroid backup on it. I had then to install the LG Update (cheat with own little Webserver and edited LMHOST) to update to V20N / V20O. Now i am on V20O......
I have finally the phone and layout i like but miss root to Backup the current ROM.So after playing hours with it - and the upcoming CMW9 or Miui ROM around the corner - i need Clockword Mod. So question again short:
How to root V20O without losing settings / data / apps?
Pls advice and sorry if i overread the solution in some of the threads - i read them nearly all....

that method is for rooting GB right? but what about installing CWM?
Got my new OB and its on GB v20b..

That method is for flashing an already rooted version of v20.
Flash it (use the same version as you already have and make no wipes after)
then install superuser.zip and you ll have access to CWM.
That s all you gotta do.
Or flash v10a or similar with smartflash, root it, install cwm and then install any custom ROM you want. That s probably even easier.

okay.. now im confused where's the real thread or link for rooting GB v20b?

v20o root does not work
hi there,
first of all, I'm a noob in rooting and flashing, etc. I have a question regarding the mentioned v20o flashing (by SergovnikRZM):
I downloaded and installed all files, but in SmartFlashTool the start button is grey, I cannot start the process.
Also I cannot choose the Com Port and the LG Mobile USB serial port as the picture shows.
What should I do? Do you have any idea?
(I have a v20o Hungarian rom and the OS is xp sp3)
Thanks in advance and sorry if it's trivial but it is not mentioned in the steps..

How about enabling windows enabler? If your on Windows 7, you should run it as admin. you need to click on windows enabler, till it shows ON.

Ok, I will try, but this step was not mentioned...
(os is xp sp3)
when I tried the KDZ update I had to run windows enabler, and it was working well, and as I see this tool is also included to root, but this step is missing
Anyway, thanks your reply I will try it

Hi! Yes, now that you say it this way thats what i have done. Because in some tut it was said to do it that way, but i guess they were talking about flashing a GB rom/zimage.

As the install guide says you are meant to flash the repack and then go into recovery and flash the rom. You will likely need to flash a gb kernel via obin and then do as hia install guide says

Ok, thanks for your help so far.
So you mean the PC version of Odin. In which state will i have to bring my phone in order to do so? Where do i get the GB kernel from?
Would be really cool if you could help me further.

Well i am not 100% sure, tbh your safest route would be to re flash a stock gb rom then root it and then try again just to make sure theres no issues, in which case you can download a gb rom from the sticky in the dev section (make sure its a older rootable image!) and flash using odin while your phone is in download mode

please start at http://forum.xda-developers.com/showthread.php?t=1424997 then/or http://forum.xda-developers.com/showthread.php?t=1329360
i am hoping of course, that you can still somehow manage to get into download mode.

I has almost the same issue! I am running speedmod kernel and i want to put back the cf-root 5.3 kernel so I flashed the tar which was included the zimage via mobile oding and after reboot the phone gave me a blank screen and no recovery! only downlaod mmod where I can manage to flash speedmod again via pc odin...
why is that happend?

Come on mate have you even read the opening page for the liquid smoother rom on all opening pages it tells you to the letter how to install and yet you don't follow it and wonder y you have a black screen. Have you installed clock work recovery after rooting your note if not search how to install cwm on you tube cursed4eva is a brilliant guy who spells it all out for you- . Please don't use the fact you a noob as an excuse as I'm probably newer than you but can read and follow instructions to the letter as the developer knows best.

W00t! The phone came back to life! Thanks alot.
Now, what i dont understand is that repack_lp1 thing. I downloaded I9220LP1-N7000-ICS-REPACK.tar ... now do i flash this one using mobile odin? Will this install the CFM?

Look for cursed4eva on YouTube watch the video were he shows you how to install clockwork then read the op of liquid smooth rom simple !

Please do some more research before randomly flashing files without having any knowledge as to what they do.
Before you start fiddling with repacks and leaked ICS based roms, read this: http://forum.xda-developers.com/showthread.php?t=1633938
If you still think it's a good idea to flash anything based on the leaked ICS builds, go to the thread of the rom you want to flash and read the instructions. Again, read the instructions and then to be sure read the instructions once more.
Then follow the instructions step by step and you're good to go.

From my rooted GB Chrack's rom I just used PC odin to flash AbyssNotekernel42CWTouchOriginalLogo.tar then I flashed Liquid Smooth rom without problem. However you should follow the instruction from their website.

This snippet of information can only further confuse a man who's mustering the courage to step into the unknown. Don't post stuff like that in threads like this. You can tell that to me or any other vet, and we'll know what you're talking about. OP won't.

I need advice on flashing

Hi there, my friend has an optimus black and runs on stock gingerbread firmware. I want to flash something new bcause the stock lags :/ I have a samsung phone and this type of flashing is new to me.
So basically what i will do is :
1.Root the phone by method one in the "starter guide"
2. Install ROM manager.
3. Use ROM manager to flash a new ROM.
Will this work or am i missing something? Thnx Is there any risk, cause i don't want to brick the phone as its not mine .

As for as roms go after u root the phone there are plenty. Sable or not is the question.

Thnx for reply but are there risks of hard bricks? Does Optimus black has flash counter?

flash counter? i don't think so
best solution is to install cwm as you can get out of troubles such as bootloops and other things faster
if you want best stability, try zeus rom but if you want jellybean, you can test it

No flash counter. It's possible to hard brick if you modify bin files you flash from SFT. Flashing ROM you can only get bootloop (at various stages of the boot process depending on how far it fot ). adb is usually accessible buy you can recover using SFT or LG R&D.
There's no know solution to recover from hard brick. LG emergency recovery tool requires working first stage bootloader.

I have 2.2 Froyo... Need help

Hello, I'd like to update my phone using Smartflash.
I have an official V20B rom which is rooted. I would like to install a new official rom but i'm completely lost when it comes to choosing the right version !
Where can I get the official V20S stock rom (which can be installed with smartflash)
Also, is there any official ICS rom ? (same, for smartflash), if so, is it fully stable ? Where can I get it ? (LG Mobile update says my phone is up to date... Huh)(I have read that you need to change the boot partition or something like that with ICS roms, is it valid for official ICS roms from LG too ?).
Do I have to unroot my phone before installing a new rom with Smartflash ?
Thanks.

1. Make sure that you have P990.
2. V20B should be a gingerbread.
3. If you read one post below yours, you could’ve find exactly what you ask official ICS for smartflash.
Cheers.

I actually have V10B sorry !
I will update via LG Tools with the kdz instead of smartflash. Is there anything to do specifically to keep my data in the phone or is it saved automatically in the LG Tools update process ?
Thanks

I think updating via LG Tool doesn't erase data on your phone... however I would strongly advise you to synchronize your contacts with gmail and backing up you apps with titanium backup in an external sd card.

Update via LG Tool didn't erase my data when I went from 2.2 to 2.3

Stock ROM through CWM

Hi everyone. I have a LG Optimus Black and I need to take it to service. Because I root-ed and installed custom rom I need to go back to stock version. I have a little problem because my computer doesn't recognize the phone anymore so I can't use smartflash. Does anyone of you know another way to return to stock version? Can I flash stock trough CWM? I need v10b. Your help would be greatly appreciated. Have a nice evening and thank you for your answers!

try to change usb port, not usb 3.0 but on usb 2.0 in SW mode for able to use SFT

I already tried that. I even tried a different computer. Does no one have a stock version that I could flash trough CWM? Even if it is ICS ore something like that. Thanks a lot anyway!

with lg Tools maybe, LGMobile Update (B2C), support, recovery phone.

you do realize that flashing even a stock rom through cwm will still not make the phone "stock". you'd still have cwm installed and need to get rid of that. try flashing a kdz instead...

His post stated he has a problem with his USB. Flashing kdz or files in SmartFlash is not an option.
The link posted above is not a regular "stock" ROM. It's a project that contains stock "recovery.img" inside the zip. Like what was discussed here http://forum.xda-developers.com/showthread.php?t=2224465
It is the same adding the unlocked bootloader together with the recovery http://forum.xda-developers.com/showthread.php?t=2160394 on a flashable zip or any .img on a certain partition.
Code:
package_extract_file("x-loader.img", "/dev/block/mmcblk0p1");
package_extract_file("u-boot.img", "/dev/block/mmcblk0p2");
package_extract_file("boot.img", "/dev/block/mmcblk0p3");
package_extract_file("recovery.img", "/dev/block/mmcblk0p4");
