[Q] Flashed custom Kernal and and want to upgrade to Android 4.4

I have flashed the ThunderKernal with swipe2wake function in my LG Optimum G Pro E988.
Now, I would like to upgrade Android 4.1.2 to 4.4.
Do I have to flash the original .kdz file first before I update the system?
Thanks all of you!

There are 2 ways you could go about updating your E988. The first method would be flashing your jellybeen stock kdz file, then without rooting the phone, download the Over the Air software update. Or, you could directly flash the kikat kdz file associated with your country. Also do note that after updgrading to kitkat you won't be able to use thunder kernel anyore.
To guide you in flashing via kdz, here is the guide to using LG Flashtools 2014 (Many thanks to Hyelton by the way, this guide saved my phone ): http://forum.xda-developers.com/showthread.php?t=2420219Then, You may choose to download kdz files with this thread (courtesy of Minniang), http://forum.xda-developers.com/showthread.php?t=2438088&page=31 (although sadly, the links might be temporarily down as of the moment)

Thank you for replying and providing good methods for me.
Do I need to wipe before I flash kdz?
And also, after I flash kdz, all of the stuffs in "Internal Storage" will be deleted?
Thank you!

No prob The beauty about LG flashtools 2014 is that you have to options in flashing your .kdz. On the guide you will see the button for "normal flash" and "cse clash". If you choose normal flash, .kdz will be treated like an update, and your files will be kept intact. This flash is useful also if you accidentally play around system files resulting to a bootloop, and would just want to correct errors made without the need to erase all files.
The second option, CSE flash, will erase all your internal sd files as it will flash everything "from scratch". This is adviseable if you would like to start fresh with stock.
Nevertheless its a good practice to backup your files as theree are times when a factory reset is necessary after flashing kdz. Better safe than sorry forthose files

on flashtools screen do make sure select type is set to "cdma" and that phone mode is set to "DIAG". If i remember it right if you choose cs_emergency as phone mode only one option will appear, i overlooked that before too.

I have e986 model, wasn't suppose to choose 3g something for this model?

LG Mobile Support Tool won't download software.

I'm having problems with the LG Mobile Support Tool. When I try "Upgrade recovery" it gets stuck at "Downloading software..."
It starts downloading fast, but after it gets about 30% or so, the download speed drops to nil. My internet is stable and fast. According to NetBalancer, the LG tool starts downloading at a steady 3mb/s, and then drops to short bursts of 50-150kb/sec. I'm not having any connectivity issues with other programs.
I let it keep going earlier today for almost 4 hours. It got to about 60% and then the tool crashed.
There's been a couple of times it said something like "Please check your internet connection, then press retry." The internet connection is fine, and clicking retry will bring it back up to full speed for a few minutes before it slows again.
What can I do?

What version of Windows are you using?

Please don't post about the same problems in two different threads. I'm guessing since you using Volume Up to get into Download mode that you have a VK810 variant of the G Pad 8.3, correct?
If so, try one of the KDZs in my signature for the VK810.4G with LG Flash Tool 2014 (Google for it on XDA). That way you don't have to have a tool re-download the KDZ every time you attempt to recover.
If you want root and custom recovery, it's easiest to get both with the 11A KDZ, then flash my ROM in my signature with the latest TWRP v2.8.7.0. If you just want the latest stock unrooted, download the 36B KDZ.
If you don't have the VK810.4G, don't use the KDZs I link to.

I wasn't sure if this should be considered a new problem, or a continuation of the other. But, I can see how that would split people's attention. My bad.
I will try your steps, and let you know how it goes.

Ok, I succesfully got TWRP and 4.2.2 w/root.
Now I have another problem...
When I flash ViKtory Rom and SuperSU, it will not boot. It just gets stuck at the red Verizon screen.
You mentioned that in your ViKtory rom thread:
5.2.2. One user has verified that on their VK810, that once they flash any version of SuperSU.zip that they've tried, including 2.46 and 2.48 beta, the ROM will not boot. You're ONLY recourse is to get into Download mode and use "LG Flash Tool 2014" to Flash the 35A_08 KDZ, and root it using @Hnk1's thread [VK810][ROOT][Lollipop][5.02] No downgrade required.
Click to expand...
Click to collapse
After flashing, I lose the custom recovery and it boots to 5.0.2 without root. None of the root methods in Hnk1's thread succeeded in rooting...
I did this successfully about 6 months ago, so I know it's possible.
EDIT: I just realized that you said to flash the 35A KDZ, and I used the 36B KDZ. I'll download the 35A one and see if I have better luck rooting then.

Re: 35A versus 36B, I just haven't updated the OP. Actually these days I recommend the 11A KDZ because:
1. 11A through 24B can be rooted easily with the Stump app in brute force mode.
2. 11A is 4.2.2, so the aboot (bootloader) doesn't need downgraded prior to installing the initial Loki'd TWRP v2.7.0.1.
Did you upgrade to TWRP v2.8.7.0 before flashing the ROM and SuperSU.zip? Flashing KDZs always returns your device to complete unrooted stock just like from the factory. You should always use "CSE" mode of LG Flash Tool 2014. "Normal" mode doesn't wipe Data or Internal Storage, but especially if downgrading, you can expect that to cause problems.
35A is just as hard to root as 36B. I wrote that tip in the OP after I thought @Hnk1 's method was more easily reproducible. Sorry for the runaround and out of date directions, but you should go with the 11A KDZ.
If you had upgraded TWRP to v2.8.7.0 before flashing my ROM and SuperSU.zip and still had problems booting, you can try wiping Cache and Dalvik again (after flashing), but I don't expect that to work. You can also use CWM Recovery (just flash CWM from TWRP). There's a thread for VK810 CWM on here plus I think I have it in my VK810 section on Android File Host as a mirror, and wipe and flash everything from there. Like I said, that's only if you tried flashing from the latest TWRP v2.8.7.0 (available in these sections) for the VK810 and still had this problem. If you do switch to CWM, you can switch back after flashing the ROM for backups and such.
Good luck!

Success!
Success! :laugh: I am now running ViKtory rom! It's debloated and rooted and sweet! Thank you so much for your help. I believe this is the 2nd time you've saved my tablet!
One last question: Do I need to flash aboot to access recovery with your rom?
Here's all the steps I took on my path to success, just in case anybody finds it helpful.
===============================================================================
To return to stock, unbrick, or prepare to root.
===============================================================================
1: Open LG Flash Tool 2014
2: Use the following settings:
- Select Type: CDMA
- PhoneMode: DIAG
- Reset time: 33000
- Select KDZ file: Use newest to go back to stock unrooted
Use 11A if planning to root/twrp
- Upgrade with CSMG Client: Normal Flash will not wipe, SCE Flash will wipe
3: LG Flash Tool will open LG Mobile Update tool. If an error window pops up
saying "Cannot connect to server..." Ignore it. DO NOT CLICK OK! It will run
it's course and the tablet will reboot.
4: Done with that.
===============================================================================
To root
===============================================================================
Use Stump Root app. (Bruteforce)
===============================================================================
To install TWRP custom recovery
===============================================================================
1: Connect tablet in debugging mode.
2: Navigate to where loki_flash and twrp.lok is.
3: Open cmd from this location.
4: Run the following commands:
4a: adb push loki_flash /data/local/tmp/loki_flash
4b: adb push twrp.lok /data/local/tmp/twrp.lok
4c: adb shell
4d: su
4e: cd /data/local/tmp/
4f: chmod 777 loki_flash
4g: ./loki_flash recovery /data/local/tmp/twrp.lok
4h: exit
4i: exit
4j: adb reboot recovery
The tablet should now boot to TWRP
===============================================================================
To install ViKtory rom
===============================================================================
1: Boot to TWRP recovery v2.8.7.0
2: wipe system, data, cache, dalvik and internal storage DO NOT REBOOT
3: Go to Mount > enable MTP
4: Copy ViKtory rom and SuperSU zip files to tablet (and debloat scripts if
desired.)
5: Install zip files (may have to switch between IMG and ZIP to see them.)
6: Reboot.
ALL DONE!

Great! You're welcome, I like hearing about successful device adventures.
Yes, the exact directions what I have at the bottom of the first post. I'm unfortunately not knowledgeable enough to solve the boot into TWRP problem with the Lollipop bootloader / getting Lollipop to boot without he Lollipop bootloader on the VK810, although @xdabbeb gave me some ideas to try if I ever find the time.

LG Support tool get stuck at 60% installing new firmware/KDZ files to reset LG ms323 phone to factory settings.
What is the solution to this problem?

Soft Bricked D855

Okay, so a few days ago I had a completely stock LG G3 D855 v30n Marshmallow. Then I decided I wanted to root it and flash fulmics. So I flashed the v30b kdz with lg flash tool and rooted the phone with rootking. Everything worked perfectly until I flashed the ROM. I made a nandroid backup with TWRP and I downloaded the fulmics 6.6 zip of the xda forum and put it onto my external sd card. I tried to flaash it onto my phone but it wouldn't work (it kept reloading into recovery mode every time I tried to flash it). I thought the problem was I was using an old version of TWRP. So I flashed my backup and soft bricked my device. I have access to download mode. Could someone please help me in unbricking my phone and is it even possible to flash a rom in my situation? Thank you very much in advance.

There was no need to remove that...it only checks for Root it doesn't harm anything.. Neither steals your files.
Nevermind.
You still can boot in Fulmics right?
If you can,install TWRP Manager and install the latest TWRP.
Then reinstall Fulmics..
Or
Boot in Download Mode and flash the stock ROM.
Then Root your phone flash TWRP and then Fulmics.
