OTA update bricked my phone. Need advice - LG Optimus G Pro

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.

[Q] E975 running e973 stock kdz

I rooted my international version E975 last night but because I'm a bit noob I didn't realise I also had to unlock the bootloader. So when I installed CWR I got stuck in the secure boot loop. I managed to get out of that with the KDZ loader through 'download mode' however I wasn't able to find the correct stock rom. Each time I tried to download the australia E975 rom it would fail download half way though, getting only 500mb or so.
I tried heaps of other links to the rom but they all seem to be broken. In the mean time I found another rom and loaded it without realising it was for the E973. So it's out of the boot loop, but it thinks it's an E973 now and I don't have any 3g/data access and the rear camera doesn't work.
So my question is: where can I find the stock rom for the australian version of E975? and ultimately I want to root, unlock bootloader and install the custom 4.3 rom. Do I first need to be back to 4.1.2 to do that? or can I do it from the wrong E973 rom, running 4.0.4?

Why not try the rooting procedure again on the existing Rom, unlock boot loader, install CWM and flash any custom Rom you want ?

That would definitely solve the problem of not being able to find the stock rom, but I was concerned that most of the guides I've read state that the starting state should be 4.1.2.
I'm worried that starting with the E973 rom might cause some incompatibility during the root/unlock/freegee/rom install...

I'm not an expert, but I believe you can flash any Rom as long as you do a clean wipe, and the hardware supports it.
Edit:
Well, maybe you better wait till a real expert confirms this.

Did I kill it? Com.Android.Phone has stopped

I rooted and used freegee to put cwm on. I tried to flash a rom but on boot it says com. android phone has stopped. I click Ok but it reappears instantly. Occasionally it also says nfc has stopped. I need all the help you guys can offer. Thanks!!!
Turn off your phone. Boot into cwm and do a restore of your backup. This seems to be a problem with the ROM, can you link to it?

It says no files for the back up. Basically I'm screwed? It was the Canadian cm10.2
use kdz updater to return to stock. or make a total wipe,push rom and gapps via adb and reinstall the custom rom again.

I've tried to return to stock using kdz but I click flash and 2 lines of code appear saying it started. How long should it take to flash? Right now I'm just trying to side load a stock variation. I'm just new to adb and flashing on computers.

That is because u have installed wrong baseband on your phone. Recover your previos stock rom and copy modem.img from it, you can find many HOW TO here on this forum. Only after that flash new ROM, copy your original EFS and modem into it.
Wrong rom or wrong kernel probably due to wrong rom. Try the above or flash a kernel appropriate for your Android version.

Lost Stock TWRP backup......

Hi there, yesterday I was trying to flash carbon onto my E980 and it kept saying it failed, so I re-read the installation guide and it had said to wipe everything from the phone and i guess my stupidity struck... I decided that I should wipe clean my phone, data and all.. Originally I had a backup of the stock rom just rooted and i forgot to transfer that to my external. SOOO now I'm kinda stuck with no OS and unable to flash any roms.. I was wondering if anyone out there had a TWRP backup of their stock ROM that I could potentially restore through the Recovery. I tried using the LG Flashtool to try and flash the stock ROM back on but all it did was stay at Ready!! even after I plugged in my phone.
Keep trying with the flash tool. Sometimes you need to unplug the phone a couple of times. Sometimes once. This will be you best option.

Question though, am I supposed to get the LG USB/Parallel Lock Key is not detected error when i try to load up the LG flashtool 1.5?
When you extract LGFlashtools there should be two dll files. change the name of the csmg_reg_key.dll to csmg_reg_key.bak
When I did that, I was able to use the megalock.dll that loads the tool. Also don't forget to change the date to prior of August 2012 and be off the internet. Follow the instructions provided in the OP of the LGFlashtool link. I didn't provide it here because I assume you do have it or we wouldn't be doing this.
Ok ill try it again after I get off work, hopefully I can get it back to stock

OK so, after i changed the csmg_reg_key.dll to csmg_reg_key.bak i got an error on the flashtool that said "The DLL for Authentication is not found!!" and flashtool doesnt load up.. I did download the flashtool from the OP's mirror so I'm not sure if that had anything to do with it but unfortunately its still not working...
Did you extract the dll from this link to that folder?

Okay so I extracted everything in the LG Flashtool rar file into my C:\LG\LGFlashTool folder along with whatever installed from the setup file, i got it to load without giving me the usb error and what not. Now I tried to flash it again, but it just stays at Ready!! and nothing else.... I've even let it sit for a long time in hopes for it to pick up the phones plugged in and start flashing but nothing at all. Am I doomed with no way to go back to stock? Not gonna lie... even though I finally got the phone to flash to CyanogenMod 10.2, i still miss the stock features of the phone.
You might need to unplug and plug the phone in, wait for a few seconds, and If that doesn't work, do it again. Sometimes several times. Make sure you have the drivers installed and you change the the date. You're getting closer.

[Q] Stuck in recovery (CWM) for no reason?

I've searched all over, but haven't found anything specific to this. I have a rooted e980 with a stock rom and CWM. It's been running great for a couple of months. I woke up this morning and it was on the CWM start screen. I figured it reset overnight and somehow got there. Anyway, I can't get it out of CWM. I've rebooted, battery pulled, and even restored several backups I had. They all complete successfully, then the phone reboots and goes right back into CWM. I even went and installed an old backup of a Carbon ROM I had, and it does the same thing: stays in CWM.
Any ideas? I don't want to keep screwing with it and really brick it.
I had the same thing happen to me as well...I tried restores...factory resets and nothing would work...the only option I had was to return stock using lg flash tools...you will lose everything on the internal sd...but the phone was up and running in about fifteen minutes...reroot...install cwm... after that I store everything on the external sd including my cwm backups... hope this helps...

Thanks. Yeah, I think that's what I'm going to have to do. Did you already have a copy of the stock rom? I'm downloading it now and it's taking forever...

It worked! Thanks! However, I had to use that same TOT file you linked. The I downloaded the stock rom 3 times and none of them worked, the extracted TOT did though. For future readers of this, some observations:
I used the TOT linked above by MythicBlue
The first time I tried flashing with the LG Flash Tool, it failed at 31 seconds, so I tried again and...
It failed again at the very end, however my phone was already fixed and rebooted, so you may need to try it again.
In the lg flash tool, check the box that lets you manually add the .dll file
the box directly beneath it is for the TOT file.
I hope my frustrating Saturday might help someone else.
My e980 did the same thing, had to use lg flash tools to get back to stock.
Anybody know what caused our phones to do this?

Someone answer this quick question for me...

Can I flash the new 10l ota with the bumped twrp recovery instead of the stock recovery? I don't have a back up of stock and don't wanna restore. In on 10h euro at the moment
If you mean by purely accepting the ota then no it won't work. If you have the zip file then yes it will probably work.
The easiest method would just be to no wipe flash the kdz of 10l then reinstall bump.

Thanks for the reply, how would I no wipe kdz 10l ice never done this before ?
I updated mine and I am on the same firmwareI did was use LG pc suite and did my upgrade from there then just use purple drake lite and flashed the bumped twrp using flashify and had no problems
Use lg flashtool 2014 which you can find on Xda (google search it) then you can flash a kdz file either a normal flash or a wipe flash it gives you the options.
