[Possible] Solution for stuck LG logo

As many of you I was stucked on LG logo for kitkat, tryed everything and im starting to think that maybe the system partition has something wrong. I tried with CWM and TWRP and nothing. Then the use x_justin says to me this things:
Install titanium backup, and in the homescreen of the app you will see your system size. It has to be 2.1 GB if you have less of 2.1GB on system partition then you have to install the lastest version of jelly bean via KDZ.
When you have 2.1 GB on system partition he told me install phillz touch cwm recovery, then enter phillz recovery and inside wipe/data cache option, select clean to flash a new ROM. Then install the Paulicat ROM, at least, this one worked for me, and some users says that is nesesary to past over this ROM and then to Custom ROMS. If you want ROOT flash also Super SU. Then, when finish ROM installation, wipe data/cache only that. Then reboot system.
That worked for me. As some of you i have tried many times and always LG logo. With this method im okay.
I used E975 10H kdz, and then cm 11, and then flashes 4.4 KitKat.
Hope this help all of you.
All credist of this method for @x_justin user.

Is there any difference between KDZs?
My Taiwanese 10f KDZ still has 1.6GB system partition.

[Q] Need help flashing CM11 on ZVC

My LG G2 is on the latest version LS980ZVC rooted and latest TWRP Recovery(2.7.0.0). When I flash the latest CM11 nightly and GAPPS, Everything is successful. Problem is when I try to boot it, it won't go passed the LG Logo. I've tried factory reseting it through recovery while the rom is still flashed but to no luck.
I am not new to flashing as I've been doing it since the HTC Evo.
I've tried for the past couple of days searching through this site and the internet on my issue. When the ZVC update first came around there was a thread in the Sprint android development section that explained how flash any rom after the ZVC update and now I cannot find this thread.
Also, When I flash Mahdi Rom, it flash and boots perfectly fine. Only problem is, I get no data and service goes away completely and doesn't come back unless I reflash the rom. But it only lasts for about 5 minutes before it just drops again. When I switch back to stock and I find that I have to go into my mobile network settings and switch from global/wcdma back to lte/cdma in order to get service back.
Any help will be greatly appreciated.

Yeah I tried that as well and I would get 3G data but phone calls or texts didn't work either for me.

Zv8 modem
The CM11 nightlies aren't made to work with the new ZVC kernel and baseband. In order to flash CM11 from ZVC you need to obtain the ZV8 modem and flash BEFORE the ROM and GAPPS. Boot to recovery and wipe everything except internal storage 3x to make sure everything is wiped. Then flash the modem rom and gapps in that order exactly otherwise it won't work. After everything flashes clear the davlik cache and cache 3x then reboot to system. Been using this method since I got my phone and it works everytime with every ROM I've tried. Also for those interested in unlocking US GSM capabilities do this then install an app called Tellinfo, from there you can do everything to change over to your GSM bands and use a GSM SIM card. I've been on AT&T for 3 months now.

ZVD, AOSP, Loki, HELP?!

Okay, so I think I understand all this, but help me out anyways please. I know that once you take the ZVA OTA you can't easily flash an AOSP ROM like CyanogenMod, and this is because something in ZVA (the radio?) patched Loki, right? So what has to be changed (if anything besides going back to ZV to be able to flash an AOSP ROM? And after doing whatever that is, can I then use Nandroids and Titanium to switch between, say CyanogenMod and the original software that came on my phone? Thanks, just trying to understand how it all works.

Your best option is to tot to zva, put recovery, flash your cm.

Ugh but tot'ing is such a PITA

Aosp are in zva radio firmware. Current is zvc radio with zvd firmware.

Okay so if I .TOT back to LS980ZVA, root with ioroot, put TWRP on with AutoRec, then make a backup and flash CyanogenMod, wipe dalvik, system, cache, and data, I should have CyanogenMod? Then will I be able to restore to that backup to be on the LG software?

Okay, last night I downloaded the LS980ZVA_01.TOT from StorageCow and reset back to stock.
Download LS980ZVA_01.TOT
Open LGFlashTool
Open .DLL and .TOT
Put LS980 into Download Mode
Start LGFlashTool process.
Plug in LS980
Phone is flashed to stock ZVA
Run ioroot
Phone is rooted
Download AutoRec and Install
Run AutoRec to install TWRP recovery
Go into TWRP, make backup
Wipe System, Dalvik Cache
Wipe Data, Cache
Install cm-11-20140810-NIGHTLY-ls980
Wipe Dalvik & Cache
Install ls980_noOC-simple-v5 (dr87's Kernel)
Reboot
Get "LG Security Error"
I tried this in several different combinations from wiping dalvik and cache to not, to flashing Kernel and not, etc. none worked, and when I restored my backup, I was stuck in a black screen boot loop (just notification LED changing colors). So help me out here, please. I'd like to be able to switch easily between CyanogenMod and LG software. I know that I can get CM on ZV8, but I kinda want my Spark.

Can't have your cake and eat it too unfortunately. ZV8 you must go

You need ZV8 modem, and you cannot flash Simplekernel onto CM11. There's not any stable kernels on Cm11 except for the CM11 kernel that is bundled.

Thanks. I finally just .TOT'd back to ZV8 and installed CM11 that way. Ugh that was a pain in the arse.

yea i spent 3 days doing this and bricked my phone bad by nor remembering to flash the kernel and not knowing about the zv8 radio.
i have read other post about the radio and it seems to throttle the speeds of your data more than anything
http://forum.cyanogenmod.org/topic/93947-which-radio-to-flash-for-latest-nightly-ls980/.
BTW for others reading you do not have to tot to zv8 just need to flash the zv8 modem.zip along with the ROM and gapps

So, I have stock zvd backup, but when I restore it, I'm stuck in boot loop. Currently on CM 11 with zv8. What do I need to do to boot into my previous stock zvd backup?

Try re flashing the zvd radio had same problem but with a cm11 backup reflashed the zv8 radio and booted no problem

I tried flashing just the ZV8 modem ZIP with ROM and GApps and it never worked. Tried several times. Had to .TOT no matter what. I spend basically a month with a new phone because I had to .TOT so many times from trying just about everything I could. Could you post exactly what you did to be able to just flash the ZV8 modem?

Cm 11 -here
I prefer Snapshots
Zv8 Radio -Here
This link jumps straight to the download thanks to Zack Miller
Full gapps - here
Thanks to the Cyanogenmod Devs
My Setup
1. Sprint LG G2 LS980_ZVC_12.tot
2. TWRP v2.7.0.0 as custom recovery
Make sure that your .zip files (gapps, cm11, zv8 radio) are in the root of internal storage.
Boot to recovery and create a backup of system, boot, and data
Then do a wipe
Then you can (install) flash your .zip files, you can flash multiple at once
Select the cm11.zip first then the zv8radio.zip then the gapps.zip
Swipe to flash
Wipe dalvik/cache
Reboot make take up to 10 mins for cm11 to boot the first time

Reverse
Can I restore my backup, flash the most current radio (I'm assuming still ZVC) and restore to revert back to my stock LG setup?

I install it like any other rom, wipe everything but internal storage, install the rom and it just gets stuck on the lg logo anyone care to help? Of I restore to my original backup everything works fine.

[HELP][E975] No Problem with KitKat roms but Stuck on BootAnimation with Lollipop Rom

Hi all.
I want to use lollipop on my E975. I have no problem with KitKat roms and I use Sling right now but however when i tried to install a lollipop rom several times, at first, they all worked perfect but after the first or second reboots they always got stuck on boot animation. I tried so many lollipop roms they're all the same about this(AICP,DU, Resurrection Remix). I used Philz Touch as recovery btw wiped cache, data and dalvik every time.
thank you.

1) Check if recovery is newest version. 2)Try to flash a stock kdz, also formatting your internal memory (do backup). Then root and install recovery and flash any lp rom.
Hope your problem is solved.

will you please provide the link to latest recovery for e975..

Same problem
I have the same problem. I have used Atmod Rom, then I installed lollipop roms. Everything worked. Once I decided to go back to stock, I rooted my phone again, but after that, when I tried to install any lolliop rom, I always stuck on boot animation.
Please help us, if the KDZ updater will help, please attach links, because I tried it yesterday, but can't find working KDZ updater. The program always stopped.
