[Q]F180K Optimus G localized via flashing to E975

just recently, I bought a Korean Optimus G for a sweet price. now I'm thinking of rooting it and installing a custom rom.
problem is, it's an F180K but was localized by conversion to E975. How do i go about doing this, do I flashback to F180K (if that's possible) or can i continue and flash E975 ROMs on this converted-F180K?
also, I'm currently using an LTE sim but not getting any LTE, could the conversion be the cause? how do I fix it?
thanks in advance for the help! on a side note, which (in your opinion) is the smoothest and fastest rom that doesn't eat up too much space (is that possible) and gives the best battery life. preference of qualities are in that order.

I also own an F180K bought from Korea. What i can tell you is that this model has only LTE 900 and LTE 1800 bands. So even if you can and will convert back its possible not to fix your LTE issue.
Regarding the roms ( this is my opinion only ) i couldn't find any rom to beat the stock. I tried many of them about 5-6 months ago. Now might be different. So my opinion is that Stock rom with root access and greenify beats everything.

oh. so that's why i'm not getting any LTE. My carrier's LTE network runs on 2100. sucks -.-
anyway, know how I can convert back to stock F180K? Can I use E975 ROMs for my F180K or only the ones tailor made for the F180K?
thanks for the reply btw, I was beginning to lose hope. anyway, what version is stock on? I'd like 4.4 KitKat but if it's still on 4.3 then I'll still have to think about it.
I also heard stock F180K has a lot of korean stuff despite changing language to english, this true?

thank you, that's very informative. I'm currently on 4.1.2 although this isn't the korean version, should I go for the original F180K firmware? my software version is e97510d-ESA-XX.
I also read there are some korean stuff on the dialer in the stock firmware of the F180K, how do you get rid of those?
last question, what's in the later versions (4.2/4.3/4.4) that's not in 4.1?

If you want to get rid of Korean-specific features and elements in the interface (like labels on the dialer), the Korean stock ROM is not for you. The E975 ROM that you have right now should be good, but I am not sure if I understand exactly what you mean by "localized"... You can definitely use E975 ROMs on F180 (I do), but it might be a bit messy, depending on your luck. There is a lot of info here on XDA regarding F180 -> E975 conversion and related issues -- read it to understand what you are doing.

The last official stock version is 4.1.2, like I said before. If you want newer versions, you need custom ROMs. Note that there is an expected upgrade to 4.4.x which should come fairly soon, but hey, it's LG, so no solid ETAs. It will come when it comes...

well yeah, last thing since I don't think this has been answered yet, can I flash to other E975 roms from my current setup? (F180K converted to E975) or do I have to use roms made specifically for F180K devices?

Do just a little searching or perhaps you did....either way anything in here labeled LS980 will work for for you....

[Q] LG G3 D850 - compatibility with other roms

Hey guys,
There are absolutely no posts on G3 AT&T android development, and I am an extremely impatient person. I grabbed the bump'd unlock the day of its release and I was wondering if it was possible to flash a D851 AOSP rom on the D850 :fingers-crossed: . What would happen? Would it run or are we talking about an immediate soft/hard brick? I figured both the D851 and D850 are super similar, having the same hardware and being GSM... however, the slight differences in radios and what not might be an issue. What do you guys think?

Please re-read the thread for Bump. In order for you to flash a ROM it will have to be Bump'd for your device. @thecubed and @Shelnutt2 (perhaps others) are currently working on finalizing the Bump process so that ROMs can be Bump'd. Just hang in there-these guys work fast, but they also work methodically to prevent issues.

thanks for the piece of mind. I figured the devs just didnt want to release a sloppy product. I cant wait for cyanogenmod for my att lg g3. Im knew here so id like to show my support with a pledge of $20 to a dev working on my model phone. Can anyone point me in the right direction?

Will there be a Lollipop Build for D852

Hey all. I am new to this scene and have been seeing lollipop builds for the D855 variant of our phones. would anyone know if there will be a lollipop build for the D852 Canadian variant of our phones? I am guessing it is unsafe to attempt to use the D855 build on the D852. Cheers.

I think so, i'm fairly new to the LG scene but hardware wise we're exactly the same as AT&T models aside from a locked bootloader so I can't see it taking very long for a port. Its been that way for every HTC/Samsung I've had here so I see this being no different.

I've tried flashing both the D855 and D850 builds onto my D852 with no success. After modifying the updater-script and build prop the best I got was getting to the LG splash screen then it would reboot into recovery. I'm really interested to know how to port this over. If there is a process to be learnt we could use it for all the builds coming out for the other variants. I hope a dev steps in to help us out!

Unfortunately it cant be flashed or ported due to the fact that the kernel signature has to match your exact device so it must be compiled for your device from source. I know @Ariesdroid is working to get some stuff going for your device, though I have no idea if it is CM12 or not.

Absolutely we will.

Awesome, thx for the info guys, looking forward to the update.

Thanks for the info guys, i can't wait to see some cm12 come out for our device

Our team is getting all the nexus/moto devices and others going first unfortunately....I am just the graphics guy on the team. They are trying to get Validus and Tesla Kitkat ROMs to boot for my d852 so i can at least use our ROMs on the g3 for now....but 5.0 versions will follow with time....
Some cm 12 would be nice as well to play around with....I heard a rumor that it might happen soon... :laugh::angel:

Will it be compatible with d852G?

Cm12 lg g3 d852
I flashed the Unoficial-CM12 one on mine last night, and so far so good, no problems yet. Everything is working fine. Let me know you want to know how I did so, and I can put together a list of how-to. Also, if you want I can report any problems or bugs.

[Q] Sprint G2 ROMs HELP!

Hey Guys,
Hope you guys and gals are doing well. I wanted to know if there is rom for LG G2 (LS980) the latest build without the sprint bloatware? The current rom installed is "ZVD" but the knock code doesn't work and the software update option is missing. I got this from a friend and I am guessing he didn't flash it properly.
so I want to know the following things:
1. Can someone or has someone worked on the ZVE rom and removed the Sprint bloatware, If yes can someone please share it?
2. Is it possible to flash a D802 rom over LS980? I know noob question but still
3. I am not in USA so if I flash the rom to ZVC will I have carrier restriction? and would I be able to update it OTA to ZVD ? even if I am not in USA?
and lastly
4. Could you guys recommend a good rom which is less bloated with custom stuff and nearer to the stock international version of the phone providing the G2 experience as it should be?
Thanks.

Try cloudyfa's ROM. It will keep you with everything you need. Do not flash a d802 ROM. You will destroy your device. You can unlock it to work. Cloudyfa's ROM will allow you to use it international as you are.

...or you can just root with StumpRoot, install Titanium Backup and debloat (frost/defrost) yourself. I've always been of the opinion that the best ROM is always a stock rooted ROM. That's just my opinion/experience, no offense to any of the custom ROMs out there.
My G2 LS980 is on ZVE, i rooted with StumpRoot and froze what i considered unnecessary with Titanium Backup. Works for me just fine.

Nice to see you still around lord lugard.
Always be careful so as to not stop something that might be necessary as you can break yourself.

So very true.
