Lg Lucid ICS Warning

[jhcii]

Ok most of us have already figured this out but for those newbies out there and those who haven't heard or tried it yet here is some info to go by before you soft brick or brick your phone.

After you have updated to ICS (4.0.4) you are pretty much stuck with only being able to root your phone.

If you try to install Clockworkmod or another custom recovery you will get a "Security Error" on bootup or even the "fasboot, fasboot, Long time no see" error screen.

If you use Titanium Backup (I do) and you REMOVE anything from the rom you will get the "Security Error" next time you turn on your phone.

If you use Titanium Backup and you INTEGRATE updates into rom, you will get the "Security Error" next time you turn on the phone.

Long and Short of it is this, if you mess with the rom, by removing or adding anything to it, you will most likely get the "Security Error" screen the next time you reboot or turn on your phone. So far I have been able to use the LG Mobile Update Tool to "RECOVER" my phone back to stock ICS, and then I have to "Re-Root". Not bad in the overall scheme of things, but remember this one fact - The tool downloads the update from LG's server, they can remove it at their whim, So until someone can figure out how to disable the security check at startup, it's not a good idea to mess around with the phone until that happens.

This is just a word from those of us who have tried these things before, and just want to warn/prevent others from the same headaches.......

And now back to your regularly scheduled programs........

Pretty sure we have a locked bootloader.

spectrum user got an unlock the other day. it required using a hybrid gb/ics kernel among other things....

Right now I'm in the process of using root explorer to copy all the files over to my external sd card so I can transfer them to my home computer. I wanna go through every folder and file to see if I can find any files that might be locking it. It could just be a simple script file but I'm not to versed in the android OS, so I'll just poke around on the copied files (It is a lot easier to look at these files on a large monitor) and I don't need to worry if I edit a file and screw it up since it's just copies of the original. To bad they have internal memory banked so you can't access it while it's hooked up to the computer, copying files and directories one by one over to the sd card is tedious, but sometimes very rewarding.........

On a side note I found the "Security Error" .png while looking around so it seems that it just might be a script that's checking.... located in res/images/errorlogo.png so guess I'll be looking through them for any call to that location and go from there.... LOL Hope this info helps out others as well.....

are you using the ics spectrum root only tool? you may need to download superuser from the play store

After upgrading i looked for an universal root method for ics phones. i found one on the XDA Forums, it works. all the credit goes them them i only found it.

I also found a nice reference to Douglas Adams' book the Hitchhikers guide to the galaxy. In the directory you'll find a folder named ETC, open it and find the file event-log-tags and open it with wordpad. It contains lines with a number then a description of it. The very first line is "42 Answer (To life the universe etc |3)

We Spectrum guys used the gb hboot partition to disable the security and a cm9 kernel injected into the boot.img to boot. But our Bluetooth and hotspot don't work being unlocked with ics.

I don't know how to do any of that but I don't use bluetooth anyway hopefully someone can work something out over here
