CM7 is EXT3, so I can't see that fix helping. NVflash back to stock, install ClockworkMod the restore /data

Need help with getting ICS on my Black.

Hey. I've been trying to root my Black, running 2.2.2, for the past few days and couldn't get it done. Tried Superoneclick and UnlockRoot, both of them didn't help me. The thing is, I don't really need the root, only ICS. I've heard there's a beta version of 4.0 for Black. Is there any way to flash the ICS stock rom, if there is one, without rooting, and in a successful and safe way?

For rooting 2.2.2, try with Blackjack (google for it or find it here)
For flash ICS ROM
1. Download the kdz file from http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP970/AFRAKW/V30b_00/V30B_00.kdz
2. convert it to .bin and .fls http://forum.xda-developers.com/showthread.php?t=1692191 (don't patch it with CWM!!!)
3. Flash using Smart Flash Tools http://forum.xda-developers.com/showthread.php?t=1448803
4. Done
Do with your own risk.
note :
Flashing using SMT will erase all of your data.
If application data on your phone now are important, I suggest you to root your device, then backup your data (I'm using Titanium Backup). You can restore later on ICS.

[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.

Help Me !

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.

EXACTLY !!
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....

How to return from New bootloader

Hello. I want to ask you how to return from New bootloader to the old bootloader. Im trying AIO tollkit with option 4, I connect device and press enter and it shows "aborted". APX drivers installed and other options from AIO toolkit working well.Please help me and sorry for my english

Hi, i used this http://forum.xda-developers.com/showthread.php?t=1975274 which flashes your phone back to GB and installs cm10 and recovery, then download and flash the rom of your choice.
download tool, extract then run the flash.bat file, turn of phone and remove battery, then hold both vol+ and vol- wait a bit then press enter and NVflash should activate the phone and up/downgrade it.

Thnx bro ! )
