[Q] Downgrading CM to v10k - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

Hey,
I´ve got CM installed on l7 and now I want to flash v10k again. I don´t want to brick the phone, so I just wanna know if I should just flash v10k using the KDZ or I need to do something with CWM before and after. What is easier? CM to v10k > v20a, or just CM to v20a?

I couldn't find any flashable v20 firmwares. And, since LG updater tool uses kdz files to update firmwares, i think it's the best way to go.
Also, after flash (through kdz), bootloader will get locked...You need to unlock it again and flash cwm.
Here's a guide to do all of the above...

Touch Screen on L5 doesn't work with custom roms

I've rooted and installed CWM 6.0.2.8 on my LG E612(V20e) using V20d+root+CWM on KDZ updater...
I've tried installing CM 10, 10.1, 10.2 and 11, Vanir, AOSP mod+Clean and Slimbean ROMs. All seem to be installed properly but once the phone is booted the touchscreen doesn't work? The only L5 Custom ROM wherein the touchscreen worked was KOLROM.
What seems to be the problem? Please help.. Thanks..

Is your bootloader unlocked ? maybe you need to update your kernel, download and install this

My LG L5 E612 is V20E by default.. I am afraid to unlock the bootloader and install CWM manually because I once experienced random reboots after doing that previosuly.. So to get CWM recovery I just flashed a V20d+root+CWM through KDZ Updater. I just noticed though that if I flash another version of KDZ (ex. V20A or V20D) that is different from my V20E default, I noticed that the backlight of the phone is dimmer? I mean on these different KDZ versions 75% brightness was just like the 25% on my stock rom V20E. Has anyone else noticed this too?

[Q] D802T with a different KDZ??

As we know D802T does not support TWRP it goes into bootloop. Any one here from Australia with model D802T tried flashing with any other KDZ? if yes can u tell me which one and if there were any issues with it like baseband etc??
I want to install roms and not able to since i cant install recoveries on it..also is there a chance to sideload rom from adb?
Any suggestions are appreciated.
Thanks

The kdz flash will just fail. A lot of people have tried doing that, it just doesn't work. Also, the problem with autorec is that it flashes a patched kernel that doesn't work with your d802t firmware and will end up bricking it. The recovery does work though. So theoretically, if you flashed a custom rom right after flashing the recovery it should work. I don't have a d802t though so I can't test it.

That requires a custom recovery and flashing twrp through adb would require Loki which doesn't work on kit kat. It's disappointing that you couldn't flash a rom directly. Maybe you should try flashing an aosp rom like cm after autorec and then go from there. Otherwise, downgrading to jelly bean through a kdz flash is your only option. You just need to find some jb firmware first.

LG D-802T firmware issue
Tried flashing custom rom (CM13) after flashing recovery (TWRP) on my LG D-802T (Australian); it started off fine but then ended up bricking the phone: "Continuous LG logo"
Tried flashing it with UK open ROM, failed again.
Did The Australian D-802T stock ROM, worked...
So concluded that it doesn't support others.

If you want to use blisspop 6.4, just flash it.
But if you want to flash Cloudy G3 you will need another LG G3 zzzzzz
In case Cloudy G3 2.2 is a typing mistake, you only have to flash the kitkat baseband first (download here --- credited to Cloudyfa) and then flash the rom.
my English is really bad, just reply if u can't understand any steps =="

No, I mean I am currently using BLISSPOP 6.4 and I want to flash Cloudy Kitkat based rom, how can I do that?
Flash kitkat baseband, then clean wipe then flash cloudy rom?
Does Hybrid bootstack work on Cloudy or do I need to flash another bootstack? Thanks

just wipe all, flash the kitkat baseband and then flash the rom.
idk if the hybrid bootstack worked with kitkat-based, cuz I have never try it. I'm sure that the hybrid boootstack work well with cloudy lollipop-based.
