My p930 is rooted and running the latest CWM recovery and CM10 nightlies. The screen is broken and I 'll need to send it in for warranty/insurance claim. I've run a CWM backup, and transferred that to my PC. Now I need to return to stock/unroot.
This thread, along with other unroot threads, are kinda old. Is SOC > Unroot still the best method? Has anyone unrooted from 4.1/CM10? Are there any other known methods?

If all else fails you could use the LG update tool to update to official ICS... I personally don't know if there's an easier way.
On the broken screen thing, how much are you being charged to replace it? You can get the digitizer glass/frames on eBay for around $40-45. There is a nice guide on how to tear-down the phone floating around the general forum which I have used three times so far : But it's pretty easy to do and would save you some time of being without your phone... and save you the hassle of having to unroot and all.

Best thing to do now is just update using the official LG updater to ICS from download mode. If it refuses to install for any reason, flash the V18f ICS update first.

I'm also wanting to go back to the stock ICS on my optimus LTE. I'm just not 100% sure what I should flash first. Currently if I connect the phone to the LG mobile software it says that my phone is already up to date. Where would I be able to get a V18F ICS update? And also once I've done that will I be able to point the LG software to Telus I don't remember since it's been so long since I upgraded my phone.

Then you should be able to follow the unbrick guide to downgrade to GB, and instead flashing CWM and carrying on from there, try to use the LG updater while on stock GB.

The v18f version is here: http://forum.xda-developers.com/showthread.php?t=1668476
The nice thing about this is that this exe will flash no matter what ROM you currently have installed. Then, after installing this, the official updater will recognize your phone as out of date and will allow you to flash to the official v20c update easily.

Seems to want to update to V10J and that's about it, never get's to V20E. Also after the update it just stays at the Telus splash screen.
I was able to load the ATT V18F no problem and then get to the point where the LG software wants to update but that's where it end unfortunately.
Guess I'll keep trying and see how it goes.

Oh, that's actually fine. You just need to do one more thing: after you get stuck on the splash screen, pull the battery and put it back in. Then hold down volume down + power button to turn the phone on (same way you access CWM if you have it installed). Then press power button twice to confirm and your phone will reboot after a little bit and should work fine from there.
HOWEVER, if it's not even the version you want, then that doesn't help you much. What version of the phone do you have? P935 from Telus?

E971 update V20D?

Hi all,
I just noticed that there seems to be an update for the Rogers version of the Optimus G...seems to be named V20D. Any thoughts? I can't seem to update to it (get an error) and I've tried un-rooting as well as re-locking, and still get "Err: 0x13e"
Any helpful suggestions are appreciated!

Tried KDZ back to stock and upgrade or perhaps KDZ install it directly if you can get it?

Thanks, that does indeed work (KDZ to stock then upgrade), but I was hoping to preserve current settings if possible...any other suggestions?

update:
Although root is lost and bootloader is back to stock, it seems flashing the 1GB KDZ over top my current settings works and almost everything seems fine so far.

I've been trying to find a change log for this update but have been unsuccessful. Anyone?

nope, i couldn't find one either. the only thing i noticed other than the software version change is that under "About phone" there is now a "Regulatory and Safety" section.

I was only rooted and it seems to have kept root after the update. Still don't know what it changed besides the about section

To me, it seems as if standby battery life has improved.

[q] zve on affliction rom

I WENT BACK TO STOCK TO GET THE ZVE UPDATE . I USED STUMP TO ROOT INSTALLED SUPERUSER THEN AUTOREC.I READ YESTERDAY THAT I ALSO NEED TO USE TWRP 2.8 . I NEED TO GET THIS VERSION ONTO MY LS980 SINCE THERE ISN'T AN OFFICIAL VERSION FOR OUR PHONE AS OF YET.CAN SOMEONE PLEASE GIVE ME THE STEP BY STEP SO THAT I CAN GET AFFLICTION BACK ON MY PHONE? THANKS IN ADVANCE.

just curious
why would you put affliction rom on your phone which runs on zvd, when you have the more advanced zve version on your phone installed
does not make sense
phone runs fine on the latest zve version, so I see no reason to change.
If you want to get rid of some the the bloat use something like titanium backup to freeze the bloat and you are fine to go.
Have not seen any rom for sprint on the zve version that works.

zve on affliction rom
Just curious to see what zve had to offer. Am now back to the great 'sprintless' affliction. Here's fingers crossed for 5.0!

Try this and enjoy

Unoffical 5.0
I've been keeping up with the thread since day one. Since I don't have a back-up [ Black Friday/Cyber Monday around the corner! ] I think I'll hold off awhile before taking the plunge. Thanks for the suggestion!

[Q] Go back to stock from CM12

So I flashed an unofficial build of CM12, literally hours before the official version came out, and now I want to go back to LG's stock software KK 4.4.2. But I'm new to flashing so I just watched a youtube video on flashing CM12 and did it. Now I can find no way to go back. I did try to use the LGflashtool, but my DL failed. Also, I'm not sure what my build number is. I think it's LG D855 10l but I'm not too sure because when I got he phone it was in English and not from India as the 10l suggests. I also have TWRP installed. I did no backup's or recovery, but the original software should still be in the internal memory right?
So what do I do guys? Did I goof?

The original software is gone, its not saved anywhere on the phone.
You need to find your stock file and flash it with the lg flash tool, its the only way to get back to stock in your situation.
Sorry, but I won't be able to help beyond that.

Well, thanks for the tip
At this point, it seems like I'd be better off keeping CM12 for a little while, no? I don't have the time or hear to fix this right now

LG G3 VS98535B (5.1.1) safe for update if rooted?

I have a lg g3 (verizon) with 5.0.1 rooted. Is it safe to update to 5.1.1? Has anyone tried? I want to but im afraid it'll break my root completely or my phone will brick. I can't lose my root because ill lose a lot of features. So if someone has tried or is willing to try that'd be awesome!

Same boat. I'll be watching this for an answer.

Reflash stock recovery and you should be fine
OTA usually removes root. You can reroot it after you install the OTA

No update for the d855 or other versions ?!

I have the Verizon G3 with 5.01. The 35B OTA wouldn't even install until I restored the factory image.

Well I recommend a clean TOT or KDZ flash. Hope this will fix your problem. Please do follow this post http://forum.xda-developers.com/show....php?t=2785089 to flash TOT or KDZ then update via OTA. Thanks!

DO NOT TAKE THE UPDATE
...if you want root, etc. Currently there is no way to root 35b and no way to roll back to an earlier version. They patched some things up it seems.
Some brave souls took the update and are stuck now... http://forum.xda-developers.com/ver...-5-1-1-ota-t3220693/post63200915#post63200915
Freeze with tibu (or delete) the system update apk to stop the notification.

I just update my rooted 5.0.1 VS985 to 5.1.1, gotta say , this new system is more battery save. i turn on the music and LG health and mobile data when i took exercise tonight for about 2 hours, and it's only cost 3% of the battery.and you know,lots of useless Verizon apps and others, but it's fine, i can disable it in app manager.

Yea I noticed that with this new update as well.
I'm little sour about being in un-rooted state.
But the battery life is noticeably better.
Maybe this option was there but I noticed new options under the developer setting where you can restrict amount of background apps running. I believe this helps out a lot as well.

Just an update on the update...
On vs985 it looks like someone was able to successfully TOT back from the 35B update, so people shouldn't be stuck anymore if they took the OTA(see post 84 here... http://forum.xda-developers.com/ver...ing-takethe-vs98535b-5-1-1-ota-t3220693/page9). Root is still not available for people who took the 35B OTA yet, but there are 2 stock based rooted 35B ROMs available now: Jasmine and Skydragon. I think the only thing that isn't functional is advanced calling because we can only use the 24b modem with the 35b ROM due to the 12b bootloaders we have that allow us to have TWRP...or something like that. So it'll be a 35b ROM and all it's updated glory - running a 24b modem.
