***lg lucid ics root***

I doubt very seriously CWM nuked anything, its doesnt even have the radio partitions in its fstab, so it cant even flash those.

Whats prolly happened is like all other LG's (and others) that have gotten ics updates. The bootloader is locked and the boot and recovery partitions/img are signed. At boot, the bootloader does a sig check and if it fails the phone wont boot.

Prolly possible, but unlikely to be able to crack the sig to forge it lol
 
Can someone provide me with a bit of info. I have v5 and V7 of your firmware in .cab format. I need to know at what version you received the ICS update and also if your firmware was locked at GB or only once you took ICS.

Ok, then I need to wait for these two cabs to download and I should have some answers for how to unlock your boot loader. GB was an unlocked boot loader, correct?

not sure who/if anyone is still trying to crack the bootloader thing.. but i know in the LG motion thread they have a temp recovery solution for the ics locked bootloader.. '2nd init recovery' from someone named 985hPaKicK, it's originally for the LG Optimus LTE2 but they managed to get it working for the LG Motion.. so would it be worth a 'try' for this device? it would only be a temp solution but it allows you to make nandroid backups etc.. maybe a dev with more knowledge on the subjuct could shed some light? :D

happy holidays!!!!

Actually, I posted an ICS rom I need tested out. If the results are good, then I can have a boot loader unlock tool finished in the next day or two. The main hangup is having a functional boot image for ICS. Then it's on to getting you guys CM10.

On GB (both spec and lucid) the bootloader was unlocked, meaning you can play around with stuff without much fear of bricking your phone. On ICS, the locked down aboot (the first partition that boots) and every partition after that. This includes recovery and boot. If you mod either, you get the security error and have to reflash a .cab file. The boot partition itself carries a binary program called "wallpaper". This program checks for certain files in /system and if they are not there or have been modded, will also trigger the security error. We got around this on the Spectrum by replacing the entire boot chain with the unlocked GB one, but you need a custom kernel to run ICS then. The stock one will not work as it checks back up the chain to make sure everything is still locked back to Aboot. The rom I built is running a custom boot image that should allow ICS to boot. If it does, then I just need the partition images from GB for the lucid and we can all it a day with making the tool. The biggest hiccup is getting a boot image that works, and the Spec and Lucid are very close chip wise, so this should work. Depending on how close they are, we may even be able to port over our CM10 build, which we're just putting the finishing touches on.

o wow thats awesome!! and thanks for the detailed explanation now i understand it all a little better :D still not on that level yet haha but i will contribute however possible..

so im assuming by what you said that the 2nd init recovery thing may not work in this scenario :D haha.. wish i had a few lucids i could test things out on for ya lol
 
On a Upgraded ICS Lucid tried running the root script however it doesn't seem to want to work for me it does the restore and its just stuck there forever doesnt get past it no matter what I do. Just got this phone today. Any Ideas or suggestions?
 
Yeah thats not working for me either. I get SU but it wont copy it over to the /system/bin folder and then make the symlink for /system/xbin

Tried to manually do it but it wont let me mount a system partition nor can I use adb remount neither works I only have superuser in the /system/app folder but I can't do anything with it. I tried to run Root Explorer but it instantly denies root privileges So I don't know what else to try at this point.

Make sure USB Debugging is one via Internet Mode > Ethernet while connected to PC and drivers are installed. Oh and make sure no encryption are on, doesn't some to work with encryption for some reason, atleast for me.
 
This is how I gained root: How to root LG Lucid 4GLTE[ICS Update 4.0.4](LINK UPDATED)[LEGIT][HD] - YouTube

It worked fine for me...also I made that video haha.

If you don't want to the video it's simple, download the rooting tools from here: http://androidforums.com/spectrum-all-things-root/637556-root-lg-spectrum-ics-ota.html .

Make sure the Lucid has NO encryptions on, if you do you MUST factory reset in order to root (Atleast I did)

Download and install drivers.
Enable USB Debug and put the phone on USB cord to PC.
USB Mode > Internet > Ethernet.
*Notification will come on saying USB Debugging is On*
Extract tools.
Run the .bat for Windows and .sh for Linux.
