[Q] Flashing Kit Kat Based Custom ROM - G2 Q&A, Help & Troubleshooting

Hi ,
I just got my G2 Yesterday , rooted and flash TWRP right away on the stock 4.2.2 . I am tempted to try out some Kit Kat based custom roms now. I have a few questions
1-) Can i directly flash KK based custom rom ( after a full wipe of 4.2.2 ) ?
2-) Would i be able to go back to my stock rom via nandroid after KK custom rom ? i.e going into recover and flashing the backup again ? ( heard there are not custom recoveries for KK ? )

1-) Yes, kinda. Just look for instructions in OP of the roms. This one works pretty well: http://forum.xda-developers.com/showthread.php?t=2667714 (Only D802 there are LG KK Roms for other variants though, just search the forums)
2-) No, there's no custom recovery for 4.4.2 yet, but devs are getting close. Read more about that here: http://forum.xda-developers.com/showthread.php?t=2667227
Edit: One more thing: You can of course flash AOSP 4.4.2 roms and will keep custom recovery.

So if i understand correctly. There would be no going back from a KK based rom except using the LG tool to flash the stock KDZ right ?

Only AOSP? I just got this phone and I'm familiar with adb and the rooting/recovery process but does this mean I could install a 4.4.2 version of cyanogen or paranoid android or BeanStalk over 4.2.2 and keep my custom recovery?

This depends on your variant. The D800 kitkat has been moded to allow a mixed match of partitions that allows the previous loki enabled recovery to run. This was released yesterday But Is only possible thanks to the release of the kernel source for the D800 from LG. Other variants will follow. In fact the D800 versions from AndroidUser0011001 and garyd9 will flash from your custom recovery, no LG Flashtool required

Thanks guys !
I think its better to stick with stock rooted for now and jump to KK when all the necessary stuff is made available. So that jumping between KK and JB is easy .

You will have to flash a 4.4 rom first ( official or leaked doesn't matter ) because you need to update your bootloader to run 4.4. No root won't stay so you will have to re-root and install custom recovery too. Also, you can't go back to 4.3 once you update to 4.4.

About the steps ? Bcoz i read some tutorial said that i need to flash 4 different files...That is for leaked firmware is it ?
There are plenty official rom release 4.4 already, if the official ones do i need to flash like the leaked ones?

Official is a single file you put in AP/PDA so it's easier and less confusing which files goes where.

Download THIS - put your device into download mode, unrar the .zip load the file into PDA slot and hit start.
It's the single Official Polish ROM

[Q] How to enter TWRP on stock Kitkat firmware?

Hi Guys,
So I tried the new stock Kitkat firmware for my d802. Flashed the KDZ through support tool. I lost root as expected.
Then I started to miss root and control over my phone, so I wanted to go back to Jellybean.
After some difficulties I got the support tool working in offline mode. Flashed Jellybean stock KDZ.
Rooted the phone again and installed recovery.
Converted the stock KitKat rom to a flashable zip, and copied it to SD card.
I flashed the zip and all went fine.
Anyhow, when I wanted to return to recovery it did a factory reset instead, and now I can start all over.
Do we have a solution to this problem?
Thanks.

We are waiting for LG to release KitKat kernel sources for D802 before a solution can be made, but it does require you to go back to JB again and then flash a KitKat rom with the modified kernel in order to keep your custom recovery

Thanks. I thought that if it was a flashable zip, I could always return to custom recovery, but of course it is the content of the file that needs to be modified. I'll wait.

it would not be just a modified kernel it would be an entirely modified zip with parts from 4.2.2 and 4.4.2 so that it can support custom recovery like in jb but be able to boot into kk in fact the only reason we need the kernel source is because we have to add some lines so it can allow jb and kk partiotions to work together

D802 kit Kat kernel source just came out a few hours ago so soon you guys should see a stock kk Rom with root and recovery support

Can't wait to see that. Is there any downsides to this method or is all working well with this work around?

I have been using it but for att and have not experienced any troubles and I also know of a few people who have already flashed roms whitput trouble also it seems like the g pro 2 rom might be the first to seeing custom recovery on d802 since someone there already made a patch but has not tested it yet and thus has not released it yet

OK... so all the kerneis are for custom roms... so sad... i like stock rom...

This is the new stock kernel for 4.4 that let's you flash 4.4 based stock Roms strait from 4.2. You must also flash the baseband when going back and forth. (I think this is what you asked for)
If youre talking about a modified stock kernel for 4.4, then no. No one has anything out yet. And more then likely won't for a bit after all devices have access to 4.4

Stock Rom

Hello guys. I need an advice pls.
I flashed a galaxy s4 i9500 (international) with sokp Rom. (Aosp based 4.4 Rom)
Now I want to flash a pure stock 4.4 Rom. Which I never had on my device. I started with custom Roms from 4.2.2, moved to 4.3 and then the custom Sokp Rom. So I need words of advice.
Is there a flashable latest stock rom which I can flash in twrp? If yes, are the steps the same as flashing custom Rom?
Where can I get a link if such?
Thanks in advance.

You can flash through odin a stock rom from sammobile or a custom rom generated from stock from xda where you can flash the zip file you pput on the microsd card for i.e. with recovery. But original stock rom which might be used to restore original condition (for warranty reasons for i.e.) should be flashed with odin or kies.

[Q] switching between lollipop roms

Hi, my g2 is running stock lollipop. If I want to try an aosp lollipop based rom I just need to wipe the old system and flash the new one? I do not have to flash any other stuff life "back to kk" or be worried about the sensors or modem, or recoveries am I right?
anyone?
no sir, if you are on stock Lollipop you are not clear to flash any ROM's, do you have a custom recovery?
Apologies, as I have not tried the OTA lollipop....how is it? Worth trying in place of a constantly rebooting CM12-based phone?
You will need to be running a 4.3 bootloader before flashing the Lollipop ROM's, so you will need to take some steps to downgrade.

So we just have to flash jelly bean bootloader true recovery if I come from stock lollipop to an AOSP rom?
And what if we want to go back from AOSP to stock lollipop?
Thx!
