Use pc suite and use "repair firmware" or something like that.

OTA update bricked my phone. Need advice

Hi all,
mt LG Optimous Pro G E988 has been working fine for 6 months,
But over night there was a OTA update, and now my phone is "stuck"
I say stuck because it will boot with the message
"Secure Booting Error"
"Cause: Device Unlock!! So Boot Sucess!!!"
then it goes into my CWM Recovery....
I had rooted with cwm
Here is where I am having the problem. It never fully installed the OTA update, because I had a boot loader installed.
I had tried to wipe everything and do a factory update, but no use.
I also tried using LG Mobile Support Tool to reflash the factory ROM
as per: http://forum.xda-developers.com/showpost.php?p=45953380&postcount=1
Yesterday when I tried it, the LG f;lash tool said it was not able to connect to the LG Server
But today the program is saying there is not enough power and may cause a problem.
I have just charged the phone for 9 hrs straight. I don't believe that it's undercharged
Is there a way for me to flash the phone with the original ROM without connecting to LG's server (using their Support Tool)?
Please help.
Thanks
Since you already have CWM installed I hope you have a backup which you can restore. Backup your apps and settings using tools like super backup or titanium. Then reload the JB 4.1.2 kdz from pc. You can look for the steps on xda forums. Once that is done successfully you will loose root. Then try official update via OTA. Or you can try to update via pc tool. Someone already shared the kitkat kdz on xda forums. You can try that too. All the best.

Unfortunately I do not have the backup anymore.
I also tried updating via the LG Mobile Support Tool, which did not work as it gives an error about not being able to connect to the server
I tried the guide from Madmack "[GUIDE] [E980] Fix soft bricks. Flash back to stock using LGFLashTools"
But I have not been able to locate the TOT file for the international E988
I tried to use the one he provided and it did not work (yea I'm desperate to try anything now)
Anyone out there have a TOT file for the international E988?
Or is there a way to crate one from the KDZ files?
please help
thanks
Not sure why you need a tot file. Kdz is fine. Look in xda for guides on loading the kdz file. That is a sure way of unbricking your phone. If it is still bricking after kdz load go jnto stock recovery and clear all caches and reboot. Most guides i have used mention this as an optional step.

Same thing happened to me with the value update. You have no choice but to reflash stock with the lg flash tool. I flashed mine with the telcel flashware but got brave enough before the kitkat update to flash back to att with .tot file .You should be fine once you reflash stock

Here is the link to the tutorial ... http://www.cellrabta.pk/2013/10/how-to-flash-big-kdz-files-optimus-g-gk-g-pro-g2-and-others/.
Note that it is not my own but a tutorial that I used successfully for my phone multiple times.
And here is the link to the XDA forum discussion that has links for the KDZ downloads ... http://forum.xda-developers.com/showthread.php?t=2438088

[Q] Help Needed! How To Flash Stock Recovery for LG Optimus G Pro

I installed cwm recovery soon after I got my LG Optimus G Pro because I wanted Android 4.4.2 Kitkat but after installing multiple ROM's I wasn't very satisfied with the battery life so I returned to the stock ROM.
I got the notification for the OTA from At&t for Android 4.4.2 but because I have cwm recovery I can't install the OTA.
I have been searching the internet and countless forums and every solution I have found hasn't been clear enough on how to return to the stock recovery.
If anyone can help me on this it would be greatly appreciated!:good:
Which version of LG G Pro do you have?
Irrespective of the version you can try unrooting using the menu entry in SUPERSU app. Then run the OTA.
I have a LG E988 which is the international version. I had ROOT but I updated using the LGMobile Support Tool on my PC. Update to KitKat went through fine and as expected I lost ROOT.

I have the LG E980. I could never find a legit download for LGMobile Support for PC, if you have a link that would be awesome

I generally trust stuff on XDA. Here is a link to the XDA page that details the process for LG E980 - http://forum.xda-developers.com/showthread.php?t=2302660. All the best.

Dont ever do this. This will softbrick your device and will cause it to go bootloop into recovery. Your best option is to flash kdz/tot. Just backup everything.

So many opinions - no authatative answers
I need to unroot and get the OTA 4.2 for mt AT&T Optimus G Pro (E980) too.
So far in this thread it has been suggested to:
1. Unroot with SuperSu and get the OTA
2. Flash the stock 4.2 with LG Tools
3. Flash the stock (pre-4.1.2 I assume) using a ROM manager I assume?
4. Never unroot with SuperSU and get the OTA as it will "softbrick" (whatever that is)
I'm a newbie to this and barely got my AT&T Optimus G Pro (E980) rooted because there were so many conflicting methods, only one worked and that was after re-installing ADB to a lower version.
What is a newbie to believe with all this conflicting advice? Is there a moderation team that will flag the correct answer?
Thanks Guys

[Q] Root+OTA

The problem is that I want to root my LG G3 D855 32gb, is there any way i can root but still be able to OTA update it?(Sorry for my bad English)
Update: I found an app called Towelroot, some people said that they can still update after root, anyone who used it can tell me if that's real cause I don't want to brick my phone or something like that.THANKS
If you want to root, do it now. OTAs can break root or patch the vulnerability. Never take an OTA until it's been confirmed safe or rootable.

For most people, OTA doesn't work after rooting. But there are some who claimed that they can OTA after rooting, and root was even preserved after the OTA.
Ota Update to 10g save my purple drake root,not problems.

You can root and then unroot to be safe to take the OTA update. There are some guides on how to go back to stock around here. One could be using the LG PC Suite and the other one, flashing a .kdz file.

Updating rooted phone

I have rooted 815 with 10b eur software and it seems like the new 10c update might help with the bluetooth issues. I tried to update before root but no update available in my country at that time. Now how could I update my phone to 10c the easiest way? I assume I would have to reset and reroot the phone in the process. Or can I just ota and reroot?

No need to do a fullwipe/factory reset.
You get the latest KDZ and flash it - if you do it right you should not loose any data.
But you will loose root for sure and you need to reroot.
As far as I read OTA won't work on rooted phones and unrooting seems not enough - you must either flash a KDZ or use LG Bridge for the Update.

lg g4 vdf UK - unroot and restore question

Hi.
I just bought the g4 from vodafone uk. I have LP and would like to root it and install exposed without unblocking the bootloader. However I havent decided if I am keeping the phone and might return it in 2 weeks.
I havent found any kdz for vdf uk to restore to stock.
Is there any way to restore back to the factory state. In case i want to return or restore?
Thanks

Check and see if there's a rooted img someone has made for your variant and a kdz. If so I would flash the rooted rom and just flash the kdz If you decide to return it they'll never know it was rooted if you completely restock it. If there isn't a rooted img just ask if someone would pull you a copy, but as long as you have a kdz your good
