We arent able to, but you can use an older unlocked bootloader and then modify the boot.img accordingly.

Also we (P970 community) don't need to unlock the new bootloader atm.We can just use the already unlocked one that Lg gave us with GB.
I am fairly the KU5900 community is able to use CWM with the supposedly locked bootloader (Or used a similar aproach we used and used old bootloader). Check their forums.

You mean to say we already have our P970's bootloader unlocked from LG? Sorry for bad English.

Download a P970 ROM in KDZ format then convert it using LG Extract tool then using Smart Flash Tool flash the bin and fls file to your KU5900 then viola you got a Korean OB with P970 ROM that has unlocked bootloader. I'd suggest flash a stock froyo rom of P970 cos its easier to root then you can install CWM.

Firstly if you have KU5900 using P970. You lose the ability to use 5GB of your internal memory.
Secondly if you have unlocked bootloader you can inject CWM before flashing with SFT.
Thirdly you can just use KU5900 ROM that has unlocked bootloader and inject CWM.

You can't. The V28C comes with locked bootloader and we need source to make a kernel thats compatible with old bootloader.

forgot to tell, right you'll lose the 5gb internal, cos that's how i did it before in my ku5900, after i flashed it to p970 rom i was able to use any rom i want. guess yours is the easier way.

[Q] Unlocking bootloader with 11w## greater than 29?

Under my battery, it clearly says 11w40, and it's been told to me that you can unlock the bootloader with the number up to 29. Since my X8 is stuck on Eclair, and I hate that, is there a possible way to get a custom ROM, with 11w40?

Its not necessary to unlock bootloader for a custom rom
first root your phone then install recovery
search for a rom for stock kernel and install it
You can use custom roms but you need those that tell "(for) stock kernel"

the translate is not good so i dont want to do it with a wrong way
Looks like you have to flash a v20 version of the optimus black with cwm injected (see in my noob how to) with smartflashtool (use search), do a factory reset in recovery, flash superuser.zip http://androidsu.com/superuser/, reboot & done. After this you can always access recovery via RomManager or QuickBoot app and you can flash any ROM you want (like Zeus, or ICS repacks,...)
No guarantee though... If you brick it, it's your own fault, not mine. Just try to read more about this topic first!
:laugh: :laugh: :laugh:
done
i use : B_SmartFlashTool_Extern
the i flashed it with another version : LGP970_V28C_00

U-boot from V30B Full Unlock

Hi Guys!
Present unlock bootloader from firmware V30B.
This is bootloader was unlocked user nikname payback from russian forum 4pda.ru and make on IDA Pro disassembler, an analog unlock bootloader on LG Optimus L7
This full work with original kernel.
Dont enter into recovery before flash it!
Enter in recovery from switch off the phone
Press hold button Volume plus and G, and press Power.
Unlocked bootloader correctly working with CWM 6.0.1.4 only
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.
Or download exe file, and switch on usb debugging mode on the phone and start exe file.
Patching firmware V30B CIS for SFT with add unlock bootloader and CWM recovery is here: http://disk.yandex.ru/public/?hash=MbUS7VP/Xt3wCJ1GisQ5g8sfgRnBUuhURSpxcqWr+jM=.
This firmware without root. Superuser in attach. Flash in CWM.
Sorry for my English.
Not bad... This is useful to Redy. Since there's hardware keys to boot to recovery. And a recovery finally for him.
I'll compile my kernel with orig boot args to be able to use this bootloader. Good job.
Isnt this the same somone has already posted...and this is not unlocked bootloader of v30 ...but bootloader of v20 pushed in v30..

Try Flashing a Euro Open found here http://lg-phone-firmware.com/ with kdz flash tool.......and please stop making so many threads about each and every question. And if you must do it then post it Q & A section. Thanks.
Ok, i will try that out. Should i flash over the existing v20a, or downgrade first...??
Sent from my LG-P880 using xda app-developers app
I do not think that you need to downgrade to 10H for that ....... If it does not work then you can downgrade to 10H but I am quite sure that it will work and you won't lose any data.
Good Luck.
You cant get eur xxx. Why would you want anyway?

Sorry to hijack the thread :good:
Did you manage to get your phone onto the EURO Firmware or you just unlocked your current firmware ?
To unlock the phone and install a custom ROM I take it that you must root the device first so :-
1) root
2) Unlock
3) cwm
4) custom rom
I am coming from a Galaxy S2 which I did not have to root just use ODIN so thats why I am asking because I want to go straight to custom CM10
I unlocked 262-001..... And
