Now if there is an exploit that can flash a prior kernel can it also flash a prior firmware by chance?

Hello,
If this is not the right place for this please fell free to move it.
Now that more unofficial roms like Cyanogenmod are getting closer to a stable/bug free release I am wondering about a few things.
According to Cyanogenmod's install guide a OLDER Kernel and Bootloader must be flashed in order to get recovery installed and Cyanogenmod running, one would also assume that most other custom roms would require this as well.
3. Flash the aboot.mbn file from VRALEC.bootloader.tar.md5 with Heimdall:
heimdall flash --ABOOT aboot.mbn
4. Flash the older kernel from VRALF2.boot.tar.md5 with Heimdall:
heimdall flash --boot boot.img
5. You should now be able to download and flash recovery:
koush's ClockworkMod Recovery: download
md5sum:3b13219e967fc622c035540107ee5553
heimdall flash --recovery your_recovery_image.img
6. Flash bootloader zipfile via recovery:
Flash the VRALE6.bootloader.zip in recovery
Install zip from sdcard
Choose VRALE6.bootloader.zip
Confirm installation
Reboot

Using this tutorial by invisiblek I obtained Root and Clockworkmod recovery some time ago and have not updated or touched the FW since. I even disabled OTA updates to avoid loosing my root.
In About Device I have:
Android Version 4.0.4
Baseband Version I535VRLF2
Kernel Version 3.0.8
Build number is I535VRALF2
CWM recovery version: 6.0.1.2
Would using the above methods to flash a new bootloader and kernel even be necessary on my phone to get Cyanogenmod running? Besides flashing the phone originally I have done nothing to change or update this stock rom.
The reason I ask is I would rather avoid any potentially phone bricking steps for installation of custom roms if they are unnecessary.
Thanks for the help in advance.
You can easily update your CWM version and bootchain (unlocked), which makes flashing custom kernels and ROMs possible, by via Odin. If that's what you wanted to know? Haha.
Well I was more wondering if I needed to even bother flashing my kernel/bootloader in order to get custom roms to run?

In order to load a custom ROM you'll need to be rooted, have an unlocked boot loader, and a custom recovery such as CWM or TWRP installed.
Most custom ROMS are based on a certain firmware. For instance Scott's ROM is based off of the I535VRBMB1 firmware but works with some older firmwares, however, it will not work with the newest firmware I535VRBMF1 (camera doesn't work).
Check this thread for newer firmwares (flashable through recovery) if you want to update yours!
Hello? Yes, I'm a noob. I tried to read and understand, but was not able to.
I have bootloader unlocked and rooted 4.4.2 stock in my m8.
I want to install the 4.4.3 roms.
My simple question would be what are the steps to get 4.4.3 radio? installed
wait to make it clear you only want the radio of 4.4.3 or the whole rom ?
but if you want to install the rom you need to have sometype of custom recovery after you installed that (you can do it through rom manager app on google play)
after that choose your rom that you wanted to install and then just flash it using the custom recovery

You didn't mention your carrier, but essentially you want to update to the latest firmware first, then flash a 4.3 ROM. To get to the latest firmware you either take an OTA from your carrier, which requires being completely stock with stock recovery and no changes to system, or flash a firmware file that someone has extracted from the OTA package. The latter is imo easier if you are already on a custom recovery. The development forum for your carrier likely has a post dedicated to updating firmware.

Go to link i posted to get your vzw firmware up to date. An fyi when you said radios you meant firmware an the radios is inside the firmware zip. After you update firmware you can flash 4.4.3 ROMs.

There is also a video in op. If you have a SD card I would go with that method but watch video read op an few times an if you still have questions hit me back.
Do i have to flash the cm12 firmware for 5.1.1 roms? I have the OTA update and running on 5.0.2?.
Yes, Each 5.1.1. ROM thread states that you are required to flash the latest firmware (otherwise you might get bootloop, flash errors).

Thank You!!
Im coming from an HTC device where flashing roms and flashing firmware were actually two seperate things due to security.
I was wondering that when you get a custom recovery on the LG G3, and flash a rom, do you have to also update your firmware as you go? Or does the firmware flash alongside the roms?
thanks
If you are referring to bootloaders and radios as firmware, then the rule regarding matching up the ROM to the radio applies as far as stock based ROMs go.
I have the latest DPH2 firmware recently released.
Suppose I want to flash a custom rom Based on previous firmware e.g. DPG1, Can I flash it through TWRP or do I have to be on the same firmware (i.e. downgrade first)?
Same question for the Kernel base as well.
