what i dont understand. in OP stand, at first to Flash the KK baseband.....
But when i Flash a kitkat Rom, the KK baseband will be installed automaticlly. Logical.
i write how i would Flash, maybe others correct my idea:

- stock 4.2.2 Rom
- root it
- Flash recovery
- install KK Rom (give enough on Forum)
- Flash the Special kernel.
- reboot
- Flash you recovery as u do it on 4.2.2

is that correct?

Right way :

- stock 4.2.2 Rom
- root it
- Flash recovery
- Flash Kitkat Baseband
- install KK Rom (give enough on Forum)
- Flash the Special kernel.
- reboot

Key point:
System Kitkat + Patched Kitkat Kernel + Baseband kitkat

The installation process can be done from a custom rom stock 4.2.2 or only from the original stock rom?

You guys can think flashing KitKat ROM just the same as flashing normal (JB) ROM with special baseband requirement (KK baseband)

so the KK ROM (or Patch), should not contains aboot.img, correct?
Yep, if you include aboot (new bootloader), then all this process is useless.

@Cloudyfa

What is a different between KitKat BaseBand of you and BaseBand that extract from kdz file?
They're the same, I just packed them and uploaded for your convenience.

Though I am not a developer or an expert in this subject.....

with my previous device LG O2X, Base bands could not be flashed with a zip file by recovery method....ONLY possible with smart flash tool or the KDZ method...so I am a bit confused and your picture confirms somewhat this.... @Cloudyfa maybe you can clarify this?

Thanks

problem solve .

I download this : https://mega.co.nz/#!dUkUCACD!aHKC-ylD2ngd8eX-jcwKVWHQt4Z2qIGEWMbKMvk8w-A
and flash via TWRP again it's ok.

in zip file contain
cust
modem

of D80210E ESA of my country


I already mentioned about cust.img, so if you wanna back to JB (D802) you should include your JB cust.img or simply clear its contents.
@Cloudyfa
...

A special thing for D802 that this variant has cust.img partition so you guys doing ROM for it must include cust.img or else the ROM wont boot. That cust.img not really important, the real problem is the old setting files and branded app in your old cust partition trying to load on new KitKat system that causing problem, so you can include the cust.img in your ROM, or use script to clear all the old cust partition.

...

With G2 we can flash it via zip file, they're in @autoprime's thread. Or you can extract it from your latest JB kdz to have an updated version.

ัyou mean I can use script

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/cust

for make rom or restore swap between JB and KK.

Hello,

I didn´t really get the use of the patched kernels. What is possible if I use such an modded kernel? I am at Europe Open KK Stock Firmware at the moment. So I can´t use TWRP etc. anymore due to the closed source of the KK Kernel of the original Firmware.
Please explain me the feature of the offered Stock KitKat kernels patched for Old Bootloader in this thread.

    Stock KitKat Kernel


    Info
    You guys already know our G2's issue with LG's official KitKat upgrade. It forces us to use the new bootloader which is loki-killer, that means no custom recovery (CWM, TWRP, Philz), no custom kernel anymore. Right now there's no way to bypass that new bootloader in order to install those stuff. Anyway we still have a workaround to deal with that issue by patching the new kernel so it can work with the old bootloader (which still has loki support) thanks to @JackpotClavin, @Savoca, @xdabbeb​


    Upgrade to KitKat
    For best experience with KitKat, you should follow these steps:
    • Upgrade to KitKat first (KDZ/TOT/OTA)
    • Root by ioroot25
    • Use AutoRec to have recovery
    Then you can flash any ROM you like

    *D801 must root before taking KitKat OTA


    Return To JellyBean
    It's real simple when you wanna return to your old ROM or your NAND backup (JB base). All you need is downloading the old JB Baseband and flash it, then your ROM / backup. You can find old JB Baseband here in @autoprime 's thread: http://xdaforums.com/showthread.php?t=2451426


    White lines issue
    Some devices use different panel hardware (JDI instead of LGIT) and you will have white lines after using patched kernel. You must use those kernel with "_jdi" in its name. More info: http://xdaforums.com/showpost.php?p=52414185&postcount=122

    *Special thank to all the DEVs here in XDA that involved in the KitKat research.

    Some devices use different panel hardware (JDI instead of LGIT) and you will have white lines after using patched kernel. You must use those kernel with "_jdi" in its name.

    For Devs:
    You should make another version of your kernel to fix that issue for those using JDI panel. By using this cmdline appending:
    "mdss_mdp.panel=1:dsi:0:qcom,mdss_dsi_g2_jdi_cmd" instead of
    "mdss_mdp.panel=1:dsi:0:qcom,mdss_dsi_g2_lgd_cmd"

    For Users:
    Show your favourite Dev this post and he'll know what he should do in order to fix the issue.
    If you're using Stock kernel, flash these kernel instead: http://www.androidfilehost.com/?w=files&flid=14480

    Any chance for LS980??

    @Cloudyfa Now that d803 KitKat has been released, can we have patched kernel and new modem as well?
    I have extracted bin files with firmware extractor but don't know how to extract further to img file for submitting here, to save you from downloading 1.6gb file.

    Sent from my LG-D803
    Maybe, please pm me the modem.bin and boot.bin you extracted.
