Does running a rooted custom rom give you rooted access? So, for me, I'm currently rooted and on V9 using LEGO rom. Are you saying that I can update to the VD radio and go back to using LEGO rom without re-rooting?
Yes, that is correct.
Keep in mind, this is a rarity and probably like many have said, because during all the custom recovery installations in this forum, you run a command similar to this:
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
This command renames a script that is used to flash a recovery image onto the phone, a piece of the puzzle that LG relies on to flash the recovery. A mistake on their part.
Most phone setups do not allow for this, so please do not consider this the norm, but you can get away with it in this specific instance.
So, since you are on V9, and assuming you already have a custom recovery installed through instructions on this forum, do the following:
Optional) Backup your apps, if you are wanting to keep them (Tools like MyBackUp and Titanium BackUp have free versions on the market, but you may consider donating to their respective devs hard work and purchase the pay version. The pay version's unlock features and speed sometimes.).
1) Download a VC based ROM (LEGOv2, nROM 1.5.2, or ThundeROM 1.7) or CM7, read more about those
here. Or wait until VD based ROM's are released....
ThundeRom 1.8 is out and VD based. Click link above.
2) Move the ROM to your SD card.
3) Use the
LG Mobile Support Tool to upgrade to VD.
4) Type the following from a command prompt after the tool tells you the upgrade is complete:
This should put you back into your custom recovery.
5) Make a nandroid backup now.
You could have made a nandroid earlier before you started the process, but after upgrading your radio to VD, that backup probably would not have went well for you if you tried to apply it to VD baseband phone. I haven't tested that, so I do not know what it would do.
6) Flash the recently downloaded VC or VD based rom, reboot and enjoy.
Optional) Restore apps, if you backed them up.
Have a nice day, that will be one click on the
