so you rooted it with smart flash tool?you don't need touch version of CWM.normally with the smart flash tool root method the phone will boot in recovery and then you just install the superuser.zip from your sd card.if you followed these steps then there will be the su app in your app drawer.if you are rooted you can always flash the zipped v20o by tantrums.here..

if there is the su app then just install rom manager from market, flash cwm recovery and then reboot into recovery and do full wipe.then you can install the zipaligned, deodexed version of v20o that i posted you above.

[Q] LG SECURITY ERROR - Bootloop on Optimus Black

I had rooted my Optimus Black right from the first week i had bought in May 2012. Tried all the possible custom ROM's out there. Huexx's Zeus ROM was my favourite. But due to power problems (abrupt restarts and excessive heating during charging) I had to give my Black to service center for repair. I made sure that I switched back to stock ROM before I give it back to the service center.
Since then, I have been unable to ROOT it !!
Tried all the possible methods to root it:
CWM Injection, Smartflash resulted into BOOTLOOP's when i tried to flash older V10 and V20 firmwares. Only firmwares that worked were V20 F and V20 G.
This got me really frustrated as I just couldnt ROOT IT.
Today I flashed European V30 with the intention of ROOTING it with Unlockroot.
This time i was successful in ROOTING.
I installed Rom Manager, Flashed CLockwordmod Recovery. Rebooted into recovery and was greeted with a "LG Security Error" !!!! The phone just wont start.
What is going on ?? Is my bootloader locked ?? I dont know ??
Can someone please help me ??

Official ICS has bootloader locked.

lg putted a "crc check" on the bootloader so if its modified like your case, it gives a security error

Does that mean I am stuck on STOCK firmware from now on ?? This sucks.
I also came across things like for the Optimus G and Nitro.
Cant anything be done regarding this matter for the Black ?
Removing the very essence of andriod OS by LG by resorting to such stupidity really DISGUSTS me.
Please Dev's, come up with something. STOCK LG roms suck ass.

yes you cannot have cwm with that rom (atleast this easy)
flash another rom with smartflashtool

Download THIS and use THIS tutorial .. you`ll get Gingerbread rooted. After this install rom manager and you can install custom rom.

Tried it but FAILED.
STUCK on LG logo with the bottom lights blinking. Waited for more than 10 mins but just stuck there.
As I had mentioned earlier, can boot successfully through only stock firmwares like V20 F, V20 G and V30. Cannot flash patched roms and neither can I flash old V10 firmware as it results in BOOTLOOP.

A lot of people flash a patched V20 and they forget to flash the Superuser and that results in a bootloop.At least it happened to me when I first rooted my OB in ancient times.Maybe this is the case.

IT WONT BOOT AFTER FLASHING PATCHED FIRMWARE. STUCK ON LG logo with blinking bottom lights (strange but true).
Tried Rom Converter 2 and 2.1, Injection Method, everything.
Patched V20S, V20O does not work.
also CANNOT boot succesfully throuh a Stock V10 (so that it becomes easy to root).

I have tried all possible methods in the above links. Does NOT work. It wont boot through a patched firmware. Seems like LG has put some sort of a LOCK for the BOOTLOADER. Only STOCK V20G, V20F and V30 work.

Did you start smartflash as admin? Disable anti virus program and firewall maybe?
Sent from my LG-P970 using xda app-developers app

Hi
This happens if you flash original v30b with smart flash and the only way to go back to GB is flash a patched v20 version....
And it directly first boots into CWM...now dont restart....just flash your backup from your memcard,this will bring your phone back alive....
You can try copy any other zip version in your memory card if u dont have backup....
The problem is original v30 formats the phone in some diff format.....
Flashing it back with CWM...brings it back alive....
If you already flashed patched version then u can try to enter CWM by console...adb reboot recovery......else do as mentioned above....

First off, I'm assuming your phone is rooted (since you have rom manager installed). Also what ROM are you currently running?
Secondly, make sure you have clockworkmod recovery installed. You then need to reboot into recovery mode, do a factory/data wipe, wipe dalvik cache and then install the ROM .zip file (must first be placed in the sd card main directory) by selecting it under "install .zip from sd card", then "choose .zip". After the ROM installs, reboot the device.

You need a patched v20 (see my noob how to). You cant install cwm on official ics. It will always cause security errors.

V28c this file i've downloaded and installed , with smart flash tool, so i have official update 4.0.4 , and when i select reboot recovery in rom manager , the phone is rebooting and it gave me an error Security Errror

Here's the noob how-to link: http://forum.xda-developers.com/showthread.php?t=1487105
Read through all that applies to your device/current ROM. Read carefully and follow the instructions. That's essentially how I learned to root the P970 and play around with different ROM's.
Good luck. If you have problems ever after following the instructions, try doing a search first. As I have found out, quite often people have run into the same problem before and there is most likely a solution. It sounds like you're still pretty new to rooting and flashing ROM's so I suggest just read, read, read.

Ok , i will read that how to , and i will try to instal v20, and i will try again.Thank you very much , sorry for my english.Good luck

As NOOBY0815 said, you can't use CWR (clockwork recovery) on official ICS. You need to flash a different stock ROM (GB 2.X.X) and then it will reboot into recovery... and then you can flash a new custom ROM.

So I tried to root my Galaxy S Advance using Odin. Everything went well until the reboot part. It's been stuck at the Samsung Galaxy S Advance logo screen for a while. What can I do ?

Flash the firmware again! Upgrade to jelly bean, if on gb, and use shaan's method to root.

That root method with Odin is for Android 2.3. You tried it on 4.1.2? If yes, then download your JB firmware again and install it with Odin (like you did with that root). And use this for root: http://forum.xda-developers.com/showthread.php?t=2087424

Guys, I've encountered another problem and I thought it wasn't necessary to open another thread. So..I managed to root my phone and I would like to install a custom ROM but I have problems with Clockwork mode. I found a thread about temporary CMW for JB and I tried it but it doesn't seem to work. I installed it but when I want to navigate through it's menus (for example going to the "install zip from sd card" menu) it restarts. Even when I try to reboot my phone ("reboot system now") it doesn't work. CWM just restarts. Any thoughts ?

Install CoCore with Universal kernel flash, and use permanent cwm. You need to unzip it, and use kernel.bin.md5 and you must have some root explorer installed.

No, you cannot change kernel without rooting your phone.
And rooting has a lot less risk of bricking phone.

[Q] PROBLEM!!! Can't flash anything bellow ics

Hi! I have an lg OB running ics 4.0.4(V30B). The phone it's rooted and I have CWM installed from Rom Manager. I can acces Recovery from Rom Manager and with the phone off ( VOLUME PLUS + G KEY). The problem is that I can't flash any Rom bellow ics (not even with Smart Flash Tools) without getting bootloops. I can flash Roms based on ics and above( IZS,CM10.1,NAMELESS ROM NIGHTLIES 4.4.4).

I was hoping you fixed the issue. I don't know what to do.
It's a matter of unlocking the boot loader. Once you do that, you can jump back and forth between ICS-based ROMs and everything else.
Gingerbread ROMs include the boot loader (marvel and Huexxx).

Did you already try the alternative way without the app? Which means load the files to your sdcard and afterwards type the dd if=xxxx of=xxxx? This could show if it works or fails. And did you ever flash the LU5900 port? So the early ICS ROM released by Redy, Gabwerkz and me. Try the manual unlock first.

OK I have the terminal emulator on my phone.
I've read the thread and it says "Move this two files, bootloader and recovery to the root of memory sdcard;
Enter in the command line
su
dd if=/sdcard/u-boot.img of=/dev/block/mmcblk0p2
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p4
And reboot or reboot recovery."
I have downloaded all on my laptop(bootloader recovery and su) but I am confuse....what's with that "su"?
Do I have to put it on the root of the sdcard too?
Sorry for my noob question
