[please sticky] to anyone trying to ota update and it won't take:

TO ANYONE TRYING TO OTA UPDATE AND IT WON'T TAKE:

If your software version is saying vzc still, and you have made changes to your build.prop. Also, as mentioned below by Mista_J, if you have removed system apps, this will also cause the update to fail. The update checks all of those for integrity.

I changed one thing in my build.prop and it didn't take, changed it back, and whammo, worked well, even being rooted.

Yes, you will lose partial root after the update. The files will still be in place, but you will have to use the ratc method via Short Fuse's Super One Click Root again, to get guid and suid functionality back. Also, you will have to do the su update in Super User, to re-update the su binary.

The only changes I've found so far is an update for the radio (I'm guessing to get the phone ready for the LTE rollout, even though it's still not switched and I'm in a LTE release city), Polaris Office, which I don't recall being there before, and the idiots actually made a /etc/install_recovery.sh, which should have been part of vzc, as far as I can tell.

Here is the recook that bypasses all checks:

(yes, I'm well aware that this isn't the most secure way of doing things, but it works.. or at least, it should.. lol)

Easy steps:

1) download above and move it to your sd card via an adb push, or simply using an sd card adapter, and rename it to update.zip (however you do it, just make sure you rename it)
2)
a) reboot via adb "adb reboot recovery"
b) reboot via an app such as DroidGrams or ROOT Toolbox Lite
3) let the magick happen! (if it prompts you, tap your home soft-key on 'apply update.zip from sdcard/', and it's obvious from there)
4) (reboot by tapping home on 'reboot system now') play with, and enjoy your updated phone

Hope this helps everyone!

Later folks,
~WickiD~

P.S. Once I figure out the whole 'magick' thing, I may have a working cwr for us!

(wow.. this means backtracking about a year and a half to my old moto backflip scripts - they do things very similar..)

I'll recook the update tonight so that it bypasses the checks.

When I do, you'll have to have it on your sd card, and reboot it via adb, into recovery, and it will automatically pickup the update.zip and install it, as long as you left the recovery stock. If not, there will be a few more steps involved..

I'm off to bed..

My phone is rooted and I've tried to update it twice. It still won't update. I didn't change my build.prop, the only thing I did was uninstall a couple of system apps. What do I need to do to update?

Did you backup the system apps? You should just be able to restore them, and be fine.

I noticed the updater-script checks the integrity of certain system apps too - i.e. assert(apply_patch_check(... is your culprit..

I'm actually glad you brought that up. I've done one recook already. Looks like I'm going to have to do another that removes all checks for those that have modded beyond build.prop.

(Updated OP, obviously.. lol)

Looks like we're learning from each other! Thanks!

So I just flashed your recook, and my software version is still LS840ZVC...

*edit*

~~And, it seems to have killed my data? Can still make calls, and am showing 3G, but it's acting as if I don't have a data connection.~~
Reboot fixed the data issue.

**Mista_J** · 07-17-2012, 03:24 PM

The ota update failed 3 times on my rooted phone. I updated using the LG mobile tools and it worked. I had to re-root my phone. It says that it's rooted but I can't update the su binary in superuser.

It took a little time to kick up data upon reboot even before the update. I've noticed this on this phone.. for whatever reason, it takes forEVER for it to kick back up, and yeah, to get it up faster, you can reboot, or do a profile update. That's the software itself, though, not anything I did. The only thing I changed in this was the updater-script.

As for the version number, I'm not sure why it wouldn't have taken.

Can you do me a favor and PM me your /cache/recovery/last_log?

That will tell me where it quit on you, and I should be able to fix it.

See, I'm sort of doing this blindly because I've already updated my girl's phone before I did this recook, and don't want to risk messing it up until we have a stable recovery in place.

What did you use to root? Because I used Short Fuse's Super One Click root via the rageagainstthecage exploit. I then used the busybox installer by jrummel to install busybox, and that seemed to work in order to update the su binary via superuser.

I hope that helps. Let me know if it does.

Peace,

Couldn't install busybox, says it cannot locate "android reboot".

Which version are you trying to install?

I can't, as there is no recovery directory showing the cache directory...

It's saying:

E:signature verification failed
Installation aborted

I'm having the same problem, I tried unrooting/rerooting, factory reset, and connecting to my computer in download mode and still no luck getting the OTA or this package to install.

**coreag** · 07-30-2012, 01:03 AM

i managed to install the update using this method but am unable to reroot the phone using ratc for some reason.

~~I ended up just finding an APK to reinstall NASCAR so that the official update would work. It left root intact after updated, to boot.~~

I stand corrected... OTA is still failing, not sure what's it's still missing. Grr.

**d_mcknight** · 08-26-2012, 08:34 PM

I had problems with the signature verification failing on zip files when I renamed them on my tablet. Is there a way to rename the package that won't cause the recovery to reject it?

Not that I've been able to find, and I've tried it a few different ways. =/

I tried running the LG update tool, and it's telling me that I'm already current on my software, however, my software version is still showing as zvc. If I'd known that deleting the bloatware would cause this much headache, I'd have happily left it be.

**Odinist** · 08-28-2012, 11:51 AM

Doesn't look like it really adds anything, though:

Hopefully by the time ICS is released for this thing I'll have been able to sort it out.

**d_mcknight** · 08-29-2012, 11:37 AM

Yeah, my only concern is that we need to update to zvd before we can get is or jb. I contacted LG, and they said to bring it in to sprint, or else mail it to them for service..

BTW, this thread will get you back to stock, after which the OTA ZVD will install with no issue: http://forums.androidcentral.com/lg-...-firmware.html

Updates disable your SU binary. It's there but unusable.

Use the unbrick method from the stickied forum to go back to GB then connect to wifi and go to System > Updates > Update LG Software,
That will put you on Ice Cream Sandwich, if you want to stay on GB when ever you see an update notification, ignore it.
