It looks like an official release is near, so if you aren't VERY comfortable with adb, etc. then this isn't for you, and please don't attempt it. As with any procedures of this sort you risk getting your phone in an unusable state and potentially worse. If you are comfortable with this and don't want to wait for the OTA, here's what I did to make it work. Hopefully this will also help others force future OTAs as the procedure should be transferable.
Manual OTA Install:
- Restore to 100% stock VS98012B via one of the available tot/kdz methods, then get root using the latest ioroot from autoprime (or do it manually). Don't install a recovery. Don't modify anything.
- Download the bin file from here and verify that the md5 is ebb9750e33574c7738a8256fb01a9e00
- Rename the file to dlpkgfile and push it to /cache/fota/
- From an adb shell run the following command:
echo "--update_package=/cache/fota/dlpkgfile" > /cache/recovery/command
- From adb shell run the following command:
am start -n com.lge.lgfota.permission/com.lge.lgfota.permission.DmcEzUpdateStart
- The phone will restart on its own and go through the software update procedure.
If you want a custom recovery, then you have a few more steps. JackpotClavin has already written up an excellent guide on how to do so HERE. Follow his steps 5-8 (as you've theoretically already followed this guide to get to 24A), and substitute one of the .lok files included in this archive for the file named "boot.emmc.win" in step 7. If you have already gone through that procedure and have a custom recovery, you can simply flash either of the following two zips:
Q: What's the difference between the two?
A: One is built with the standard 4.6 gcc toolchain (same as stock LG) and the other is built with a linaro 4.7.4 optimized gcc toolchain.
Note: In order to have a custom recovery you need to be use an older (12b, 4.2.2) aboot/bootloader. At the same time, your laf partition (which is the one responsible for download mode) is now based on the new 24A OTA and won't work with the older aboot. All you need to do to get a working download mode again is dd the laf partition from 12b. You can find it right here. Since the only way you got to this point is by using dd to install an older aboot, I'll assume you can do the same thing for laf.
Devs: Feel free to use the kernels in your roms. Just give credit in your OP.
