Can someone explain the N4 conversion? - AT&T LG Optimus G

So, I understand the process of it.. but not really as to why.
Are you able to install anything N4 you want? Roms, kernels, etc? Or is it just the N4 converted roms from the dev section?
Is everything working? I've read mixed reports.
Thanks,
Nicholas

The lgog and the nexus 4 are fairly similar phones. The reason we can't run nexus 4 ROMs is because some differences in the partitioning. Flashing the modified tot for the conversion converts your partition layout to that of a nexus 4 and installs the stock nexus 4 rom with an unlocked bootloader.You are supposed to be able to use nexus 4 ROMs and kernels. I've flashed like a 3 different nexus 4 ROMs
The problems that you might run into are with lte but that is fixable.
There is a fix for capacitive keys , nfc , and the external SD card which I were originally not working. The fix is a ROM so if you want all those things working you have to use it or properly patch another ROM with some of its files. There is also a flash able zip that but it is only compatible with certain ROMs.
The only "issue" in not having the full internal SD storage. You only have 8gb in comparison to 16gb but having large external SD should help storage wise.
However, apparently the conversion breaks the camera for the jelly bean stock port from the lg e973http://forum.xda-developers.com/sho...an LG-E973/1/5/0 CANADA / ATT / INTERNATIONAL. Camera works fine on every other stock based ROM when you convert back but apparently not on the jellybean port. It has not been proved but it has many claims supporting it. My camera does not work and I have converted.

Dr0!d thanks for explanation. I have a question. Ever time I come back to stock I get an encryption error. What am I doing wrong?

I got that error once. lgpnst doesn't really wipe partitions correctly before flashing ROMs. NownI wipe all of my partitions in recovery and then fastboot -w in command prompt before flashing back to stock . A data and cache is probably all that's needed but the flashing process takes a minute and I haven't had time to try it out. I think there is also something you can do at the encryption screen . it says like reset phone or something I think I've read that if you keep hitting it it will reset your phone or something idk sorry.

I tend to go back and forth doing the N4 conversion and back to At&t stock. I get this fail to encryption screen,some times after I LGNPST back to stock. Pressing the "reset phone" repeatedly never does anything for me. What i've been doing is when this happens is, I'll shut the phone down and press the Vol down and HOLD first and then hold the power button. It will bring you to some kind of factory recovery where it says "HARD RESET MODE" Just press the power button to confirm the reset and it essentially just wipes the phone and brings it back to stock.
Hope that helps!

Thanks so much man!
Are there going to be any AOSP roms coming out native for the LGOG soon? If so, I'll hold off on the conversion. But if not, then I think I'll go ahead and do the conversion and flash Ginsex or one of the other JB ports. Are the cameras working on this if you flash the fix?

Yes there are a couple of people working on aosp ROMs right now just give them a little more time

I know some people are against the conversion as such, but I think in the long run, this will be the only benefit of this phone - I'm expecting LG to do its thing where they don't provide any updates once their newer phones come out.
And here comes the nexus4 conversion - we'll be able to advance our phones thanks to the actual updates for nexus4 that google and the community will provide. Probably we'll lose LTE at some point when the modems will no longer be compatible with newer android versions.
My previous phone, the captivate was in a similar scenario - slightly different from the international galaxy s, but the devs worked out a set of patches to be applied against the galaxy s roms to make them work on the captivate and the captivate has long lived since, becoming one of first phones to get cm10.1 nightlies and enjoying more than a few 4.2.1 roms. It's definitely slowing down, it's been more than 2 and half years since the phone launched and people have moved on to newer devices.
So if it wasn't for the nexus4 conversion, I wouldn't have jumped on the lgog for my upgrade - the phone shipped with ICS, might get a 4.1 update eventually, but I don't expect LG to follow up with further stock updates after 4.1.
I know there is speak of AOSP roms coming to the LGOG, and I'm really thankful for the all the devs who work bringing these, and hoping we'll even see official cm10.1/cm11 then probably we won't need the conversion at all, but if it doesn't happen, or devs give up on the lgog the conversion will be the only path to newest android.

I still dont understand why any dev is working on anything other than perfecting the n4 conversion. Doing anything else seems like a huge waste of effort and time to me. A perfectly functioning n4 conversion = this phone will be in the game for years and years. Anything else just means everyone is sol when the developers for this specific phone jump ship.. that will never happen with the n4 conversion.
There is also the odd (cant put my finger on it) veil of secrecy with this phone that i never bumped into before. So much info no one knows because its just simply not shared in any way.

While I personally don't really agree with the first comment (I feel as though stock LG development has its place and there are dangers to the conversion), I definitely agree with the secrecy, on my old inspire I knew just about everything the devs were working on, what was and wasn't working, as well as which problems they were facing. With the LGOG I feel like I'm in the dark quite often.

This phone is already essentially a N4. We are working on methods of porting the nexus 4 kernel to our phone that do not require any modifications, so we will always be able to run anything the n4 can run anyway. Basically, there will be a longer wait because this is harder to do, but it will be better in the long run, as we fully understand what is going on.

Accept that the problem still stands with a ported kernel doesnt it? You guys leave and we need a new kernel and are s.o.l. . Also please dont take what im saying as any kind of insult, its not. Just looking to understand better.
Though i guess the same could be said for a perfected conversion is something in that needed changing.

Of course both would need kernel changes to make everything work 100%. Either way, someone would need to fix things. Fixing the kernel to boot with full stock may take more work, but I would consider something that does not require modifying the non "normal" partitions of the phone to make work better than something that modifies the base bootloader of the phone.

HA! thank you! i HATE this stupid secrecy thing that alot of people in this community have. i have also never experienced anything like it. it really keeps things from expanding. people in here know that they run the risk of damaging their phone anytime they flash anything. the reason these people are keeping things secret is because they think that "dumb people will brick their phone". i have personally been running a solution to running n4 roms/aosp stuff without having to do any conversion for multiple weeks without any harm to my phone. i have a completely working cm-10.1 rom with full internal (16gb), full access to external, cap buttons, led lights, LTE, etc. everything works but i was told by members of team codefire that if i release it then i am an effing moron.

Who cares what team codefire thinks just keep doing what you are doing and thanks for everything can't wait to try something out. If you need more/any tester just let me know I have best buy insurance so not worried about bricking.

I'd like to just chime in and say 1) one person said you'd be an effin moron and he is far from the whole of team codefire. His words and actions don't represent the team as a whole, and his words were uncalled for. He could have said things in a nicer way. 2) The cm-10.1 you have relies on a testing version of freegee that was developed, but since abadonded. The reason it was abadonded was quickly we discovered that it bricked sprint radios. We had 4 people, including myself, loose radio. Thus this new freegee method was dropped.
We are instead working with 3.4 lge kernel source. I've also narrowed down what I believe the issue is on mako kernel not booting stock, to be the lge power management vs caf/mako power management. We'd probably have lge 3.4 working by now, but all of us, sk8 included jumped on using mako kernel once it was discovered about this slightly different freegee method. However like I said, after we bricked 4 radios on sprint, we didn't expand the testing any further and stopped.
