Rooting the v20c firmware ??

i have recently upgraded to v 2.3.4 and its giving me a real hard time , lg promiced better gaming performance and battery life , so far ive only seen apps crashing games lagging like hell and real slow performance and only about 60 mb of free ram at any given time .
i'd really like to root and install a custom rom on this device , i've heard about gingerbreak and superoneclick but none of them worked with me so can anyone please give me a link or something to a guide on how to root this device ??

Check out NOOBYs How To Thread. Its a sticky somewhere. Gingerbreak and Superoneclick only work on certain versions. Rather use Smart Flash Tool to install a patched ROM.

The new rooting method is generic it install new firmware already rooted and is not dependant on what software the phone is using ( why it's also a recovery method )
The older rooting methods fool the OS into giving you root permission through various exploits and then properly root it with its new permissions. The older methods relies on vulnerabilities and that is why a lot of rooting tools don't work after the software has been patched.

Its highly subjective. Its depends on what you prefer.
I think Zeuz is the best ROM at the moment. CM10 is fast becoming very good. There's still a few minor bugs but its getting better and better with each nightly. I really like the way the V30 Repack looks but there's a few bugs that are quite annoying like USSD codes don't work and SD mounting doesn't work fully.

You can use ANY software you want. You should maybe choose v20s Europe Open. Or Any UnitedArabEmirates version from here: http://lg-phone-firmware.com/index.php?id_mod=1#united arab emirates
I guess, it's also the version you are looking for

Yes I am, the first step is to download my patched ROM, then follow the guide

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..

[Q] Is There Any Cwm Flashable Stock Rom?

After flashing numerous custom rom, I want switch to stock rom but I'm too lazy to do it from pc and odin. Is there any cwm flashable zip stock rom? I mean stock, not based on stock. I don't want to lose the root access after flashing too. I really appreciate if someone give me the link because I can't find any. I always find either odin flashable stock rom or stock based custom rom, not cwm flashable stock rom.

In the past i found a stock rom prerooted in a flashable zip.Search a little in forum and if u dont find it tell me to search

Random thought in my mind: Why the **** you want to flash the stock rom from cwm recovery.
If you're attempting to find an alternativr for Odin, well lets face it, mobile version of Odin is available, though I'm not sure it works on sgm.

The **** I'm trying to say is I want to use the convinience of CWM rather than using my pc to switch between stock and custom rom. If you don't get it, get lost! Don't even try to answer my question.
