It'll always work. Unbricked my p970 many time using this method

You can also try find KDZ for your firmware and try CWM injection method (http://forum.xda-developers.com/showthread.php?t=1512203) just use google to find your kdz. didnt work for me though

http://forum.xda-developers.com/showpost.php?p=22597935&postcount=3
Follow this guide and you can flash it over and over again and it will always be ready to root

What does that have to do with the V20J version that the OP asked about?????
I am also trying to root the same version for my girlfriend since she got a job at Koodo mobile and got stuck with this phone which with stock software is garbage compared to her old HTC Desire.
I've been searching for a while and not found anything to do with this software version except this post where you arrogantly told the guy to search first.

I've the same phone and the only way I managed to root and keep stock rom was downloading the v20j kdz file and following the cwm inject method. You'll have to find the kdz file, its here somewhere though
Edit: http://lg-phone-firmware.com/
Make sure phone model is selected and hit ok

I've since given up. I cannot find a working source for the UPK file to perform the CWM injection method. Also half the tutorials and download sites are in another language or converted to English making them less clear because of the translation.
Its my girlfriend's phone and she has no backup she is allowed to use at work so I don't want to risk causing it to be down for any amount of time. She will have to put up with it and bite her tongue when customers ask if she likes it, lol.

I have a question about this one; is there a kernel or a radio version that will prevent you from doing the passimg to FRG33? It would be useful to know it, in order to avoid even trying it.
By the way, working on stock GRI40, would i have that problem?. I made the manual upgrade from FRG33 to GRI40, flashing all the time stock rom's from Google.
I've no idea what causes the "main version is older" error, so it seems like the only way to find out it's to try. Theres no risk in trying, except a few minutes of your time...
I've heard people suggest the hboot may be the problem, or the radio, or this, or that, but I've never seem anything to bring me to the same conclusion...
I believe efrant suggested that refurb phones may be the ones effected, and I'm kinds thinking he may be on the money...?

Should work. The only potential stumbling block is the passimg step, which doesn't work for a small number of people (no idea why)...

I've downloaded frg33, renamed it to PASSIMG.zip and moved it to the sdcard (Root folder), yet when I boot into hboot it doesn't recognise it (Does the search but then nothing). Any solutions?

If the zip holds another zip then use it.. I once failed to use rom just because of that.
Nope just files.
Make sure it's not named passimg.zip.zip (Windows often hides the extension).
Sent from my Nexus One using XDA Premium App
Nope, it's PASSIMG.zip. I'm not sure if the file is corrupted, I tried downloading it about 3 times so far, none of them have worked.
Even if it's corrupted, your phone should still see it, and report an error.
The only reasons the phone wouldn't see it would be if the file is named incorrectly, in the wrong location (not on root of card), file is missing, SD not mounted, etc...

Your only option then is to unlock your bootloader, or wait...
Is your phone a refurbished or repaired one?
Sent from my NookColor using Tapatalk
No its not refurbished. I just got this phone new and it wasn't rooted to begin with at 2.2 and I made the mistake of updating to 2.3.3. I am assuming there will be a development in the works for this issue or another walkaround to this.

Rumor has it that the author of rageagainstthecage has a version working for Gingerbread, which is known as Gingerbreak. He's waiting for more phones to be updated before releasing it though...

Need Baseband for LG Thrill

Guys,
Tried to install the GB on THrill and it was installed successfully and only was getting 3G speeds. In the process of installing GB, there is a part where we need to update the baseband to something and since I didn't like it, I reverted back, But I am getting only Edge where ever I am going. Earlier I get H and H+ on AT&T. Anyone knows where I can get the baseband file for LG Thrill so that I can install.
Any advice is appreciated as well.
Guys one of our guys found the baseband for LG Thrill. Please check the post
http://forum.xda-developers.com/showpost.php?p=19440931&postcount=48
Great Thanks to him..
Try installing thriller only thing I can suggest, I have gave my warning and said wait for dev supported gb. When I had the Atrix installing the leaked gb caused some bricks and unforseen complications, like not being able to revert back.

[Q] Help plz!!

A friend tried messin around with his tab when he doesnt even know how to jailbreak an iphone 3g... The tab wouldnt even boot past the Samsung Galaxy Tab screen, but it was able to get to download mode... I used a guide to update it to gingerbread using odin, and everything went well! I opened odin, selected PIT and chose the P1_add_hidden.pit file, then i selected PDA and chose the P1000NVFJP6_P1000NUBJP3_P1000NUUBJPB_HOME.tar.md5 file, and i made sure i checked Re-Partition, Auto Reboot, F. Reset Time, Phone EFS Clear and Phone Bootloader Update.. everything went well, but on recovery it was unable to update the systemfile.. but everything else on recovery updated and installed fine! as it reboots, it gets stuck in the bootanimation in the part it says Samsung glowing.. did i do something wrong? how can i fix this? I am still able to get to recovery and download mode fine..
Use overcome method like described here

Btw, you should not have checked Clear Efs.
The replace bootloader too.
And best to use Odin 1.7 included in the gb stock safe in that link I give you.

Why do some people think its rational to use absolutely ridiculous titles like "hlp plz" etc etc??
Please use common sense and use descriptive titles, ie a short title that describes your topic for people browsing the forum. "help plz" does not describe your topic in absolutely any way other then somebody using a completely generic title.

Yes, there is a lot of reading to do, if you want to study it all.
I dont think SuperOneClick is meant for ICS, I will recommend you to look at this:
http://forum.xda-developers.com/showthread.php?t=2028946
And then I would suggest you try option 2 in "How to get root". You dont need to download ICS, you already have it.
Good luck.
