Ok, it's clogging up multiple threads, so I'm going to put all the info here. The situation : You took the ICS update. It doesn't matter how, but you took the ICS update. Your phone now gives you a security error message. The cause (1) : You were on another non-stock rom/kernel (BO, BP, etc) and did not wipe before going to ICS. The solution (1) : YOU NEED TO WIPE WHEN GOING BETWEEN ROMS. There is no ifs, ands, or buts about this. You need to wipe. Turn off your phone. Power it back on by holding vol down and power together until the factory reset message pops up. Press power twice. Your phone will factory reset and then boot into ICS without issues. The cause (2) : You took the ICS update, and rooted. I don't care if you froze something, removed something, etc, but now you have a security error (and yes, i've heard it all so don't b.s. me and say you didn't). The solution (2) : Factory reset your phone by powering it off then rebooting it by pressing and holding down the vol down and power button until the factory reset menu comes up. Press power twice. Watch your phone reset and hopefully boot into ICS. If it does, then you froze something you shouldn't have. Don't do that again. If you still get a security error, then follow the instructions in this thread to reflash V7.

Then flash the cwm_bootloop_fix.zip file. Reboot into your rom. Now here is the critical part. Update your copy of CWM. You're a whole version behind where you should be.

Flashing LG signed Firmware - LG Spectrum - RootzWiki The cause (2) : You keep being pushed into CWM, but rebooting your phone pushes you back into the OS without any issue. The solution (2) : Follow the instructions in this thread and flash the V7 .cab . http://rootzwiki.com/topic/17823-flashing-lg-signed-firmware/ If you were on pure stock, you should not need a data wipe. If you encounter any weirdness, do a factory reset once you've flashed the .cab file. The situation: You are on ICS, but hate the locked boot loader or hate something about ICS (wifi tethering being broke, etc). The cause (1) : You hate ICS and just want GB back. The solution (1) : I can not stress this enough. There is a chance you will lose data connection if something goes wrong. I've done it a dozen times with no issues, but I also have a lot of experience doing it. IF you are not comfortable with that risk, wait for the un-locker to be published. Factory reset your phone. Then follow the instructions in this thread. Flashing LG signed Firmware - LG Spectrum - RootzWiki Use the V6 cab instead of V7. This will downgrade you back to gingerbread and the unlocked boot loader. Feel free to re-root, cwm, custom-rom, etc. The cause (2) : You hate the locked boot loader, but love ICS. The solution (2) : Be aware, the custom kernel we're using has a few issues. One seems to be bluetooth connections. The other seems to be ADB shutting down after the phone has battery reaches 100%. We're working on the bluetooth stuff and for ADB, just restart your phone while it's connected to the PC. Linux bootloader unlocker: http://androidforums.com/spectrum-a...oot-cwm-lg-spectrum-4g-ics-linux-install.html Windows bootloader unlocker: http://androidforums.com/spectrum-a...20-bootloader-pwnage-tool-lg-spectrum-4g.html The situation: You want the update, but the OTA updater keeps failing. The cause (1) : You're on pure stock (no custom kernel or any other mods)(root or not rooted) Gingerbread and the OTA updater keeps failing. The OTA updater sucks. Period. The double update also feels very much unnecessary. The solution (1) : Follow the steps in this thread and use the V7 .cab . http://rootzwiki.com/topic/17823-flashing-lg-signed-firmware/ If you are on true stock, you should not need to data wipe. If you run into any weirdness, you will need to factory reset your phone after flashing with the .cab file. The situation : Your phone is on ICS and now you can't get it to connect to your computer no matter what you try. The cause (1) : Something in either the unlocked kernel or in V7 itself turns adb off and doesn't turn it back on. This is either an init setting we haven't fixed or something in usbhub switching. The solution (1) : Reboot your phone with it attached to your computer. ADB starts on boot always and so does the USB hub. It's a PITA, but it's the current work around until we find the real issue. More info to come as the questions become asked. This should cover almost everything I've seen so far.
