Solution for "Security Error"
One of the reasons you may be rooting your Nitro might be to remove bloatware. At least, that was the main reason for me.
Anyway, after you root and go about customizing and deleting apps, you will likely find yourself rebooting and being greeted by an LG logo and the words "Security Error". Then you go through the terrible motions of unbricking your phone
and trying again only to brick it once more.
Well, after bricking my phone a good 30 times, I have found a solution. Here it is:
DO NOT UNINSTALL ALL AT&T SYSTEM APPS
There you have it. It seems that AT&T has set up their ROMs to verify that all system apps are intact at boot. If they are not, they assume that the ROM has been tampered with. Of course, this does not mean that you can't freeze these apps. I used Titanium Backup
to freeze these apps.
When I finished customizing my Nitro, I booted into ClockWorkMod Recovery and made a backup. Each time I bricked my phone while testing this, I just restored that backup. I've also kept the backup on my SD card just in case.
Here is a list of the apps that I have found will brick your Nitro if removed:
- AT&T Address Book (Safe to remove with v20c update)
- AT&T Navigator (Safe to remove with v20c update)
- Google Play Books* (Safe to remove with v20c update)
- Google Play Movies*
- Google Play Music (Safe to remove with v20c update)
- Google Play Store/Market
I have found that these ones will defrost on reboot.
