Root Security error on rooted Spectrum (stock ICS)

[bhl62]

I found I was missing some contacts from the phone and wondering if it was due to Backup Assistant & Backup+ being frozen I defrosted them from TB and rebooted, then got the Secuity Error screen.

I'm not entirely sure if the defrost caused it or if it was related to converting all the updates of stock apps to system apps with TB last week (I think this was my first reboot after that). If so, my guess would be Play Movies DRM check gets messed up from the conversion as well and not just from freezing (see Root Warning thread).

Questions:

1. Is flashing back to stock ICS using the procedure at Flashing LG signed Firmware - LG Spectrum - RootzWiki the only step from here or are there any other possibilities before going there?

2. I presume VS920ZV7_15.S7_15.P58014.R5 is the most current stock firmware for the Spectrum.

Thanks for your help.

Thats pretty much the case here. yes that is the latest firmware as well. God thing is you will lose root but probably wont lose any data.

UPDATE: I tried a factory reset based on a suggestion in another forum but that didn't help, so I went through the steps to reflash and it went through like a charm from my Win 7 x64 PC.

Note that it restored the phone to as-new condition and did not leave all installed data and apps as was implied in other discussions. It went through the whole initial configuration steps for accounts, etc like a new phone. It also didn't auto-update apps previously backed up on Google servers like I've seen on my Asus Prime after a factory reset (the save/restore boxes are checked). Is there a way to force it to do a restore?

Thanks to everyone who made tools and information available in all the various forums.

I found that Google has a different MEID for the device so it isn't treating the previously backed up data as belonging to this device. Anyone know how to change it?

The flashing didn't wipe your data, the factory reset did. If you had not factory reset, all your data would have stayed. As for your other question about the MEID, I believe your have your terminology wrong. MEID is tied to the phone for your carrier to see and is not something tied to your google account. And no, we will not tell you how to change your MEID as that is against forum rules.

I didn't expect the factory reset to do anything since that was when the phone wouldn't get past the Security error screen. If it did in that short window, then oh well!

Regarding the MEID, my assumption was that re-flashing changed whatever Google uses on their backup system to identify the device. I'm referring purely to what they show on their dashboard page, not trying to change my phone in any way. There are two entries for the same VS920 on my google.com dashboard, one with a last-accessed date from yesterday (before it soft bricked) and one from today after reflashing, but with a different MEID value (last 4 hex digits are different). I was wondering if there was a way to reset one of the values on the Google server so that it recognizes them as being from the same device. (Plan B of course is to root again and use TiB to restore everything and not worry about the Google backup).

Upon loading, titanium backup defects the android id has changed and well prompt you to revert it. It may restart the phone without warning as well.

Although by now you may have discovered this on your own.
