[Q] Alittle help From a Developer - G2 Q&A, Help & Troubleshooting

I'm bout 80% done with building a ROM. It boots like a champ lol. Just seeing if a Dev. Could take a quick look over it before I publish it. Would be very thankful. Since this would be my first release.

Not a dev(or cook..), though I can test it.
id is d802 or maybe other variant ?

[Q] Just a few questions!

Hi fellow G2 users!
Got my G2 a few days ago (I know I'm about a year late) but this phone seems awesome. Model is D802.
I did a lot of reading before doing anything and so far - I am on stock LG rom, rooted, installed TWRP with autorec, flashed a volume mod and installed xposed with g2 tweaksbox. So far I have nothing to complain about.
Anyway, now come the questions - my previous phone was a sensation, and to have that fully ready to flash, it required unlocking the bootloader, S-OFF, radio flashing and root.
1. Is there anything else I need to do here? This is my main question. I did a lot of reading before posting this or doing anything to my phone. I only do something once Im completely sure I know how.
2. I've read about flashing modems of some sort and came across this link - xda wont let me post links for the 1st 10 posts... Its a site like codefi.re/autoprime
Can someone please tell me what the 4 different versions of the D802 files are?
3. Any recommended ROMS/kernels that are absolutely brilliant? I know that all devs make great roms but with specifically battery life, STABILITY, and all the LG features (like knock on and the new message reply box thing and quickmemo, etc) I have heard a lot about Pardus. Might try that out soon if I dont get any other recommendations.
4. I read about Jishnu's camera mod. The links have been deleted from his thread. Is it okay to ask if anyone has a backup? I would like to try it if possible.
5. I read about Viper Sound Mod. Is there an updated method of installing this on stock rom? The thread I found seemed outdated and half the links were invalid
Nobody?
Depends on what you want. Have you researched aosp roms? All the things you looked up are fine. Tweaks for a ton will help enrich its use but to change to a complete different operating system is what you should try out if you want to see something different. Modems usually come with the rom. Make sure you flash the correct variant for your device.

Lollypop porting

As some of you know i'm working on a N6 (because of the qhd screen) lollypop port since 1 month (really?^? sooo much to port 1 rom?) ^^
My last result is a half bricked device because of kernel incompatibility with L... (i'm lucky that i still can pull out the battery).. The only kernel source available is the Lg one.. some of you like @Tectas made an incredible job with their source (thank you.. you really helped me a lot for developing, and thanks to @sykopompos for his incredible help and friendship). Anyway main problem with L is not the rom itself...everything it's in place and surprisingly it's recognized by the bootloader in last_kmsg... the real problem is an error that i coulden't get rid of.. is a kernel panic due to the MODEM! Here the link to see what happened.. Googling for that error i found a lot of people with the same problem in old version of android but no one with a fix (aww c'mon!!) anyway... i tried every possibile fix cherry-picking and coding for bypass or avoid or to solve this problem...but it remains... any help would be appreciated but i'm afraid we'll all need to wait for LG to release the L source for G3.
If someone wants to help i'm really happy to work with everyone

If I were you I'd wait for a proper bring up of G3 + CM to 5.0, there are to many variables to this, I mean heck, even on 4.4.4 when i build I deal with a ton of build errors I need to solve.
IF you got LP to even boot on the G3 it would prob work very bad at this point.
just my 2 cents
i'm not sure at this point because all the hardware is recognized by the bootloader but at that point the modem get a fatal error that is not even described..

did you by chance check out the 4.4.4 kernels for lg g3 on the modem part. I know they're different, but maybe it might give you some clues on how to fix the code.
wich kernels?
Are you trying port 5.0 from the n6 system img? Probably never going to work bud
Sent from my VS985 4G using XDA Premium HD app
i think that once i will figure out how to fix the kernel panic it will start to boot at least ^^ with all it's bugs but it will boot

Help from experienced Developers!

Hello devs,
I have had a Micromax Canvas 2 Colors phone since a year and a half now. Custom/Themed ROMs were uncharted territory for me till June of this year, when my warranty was about to expire. I decided to use the VionicL ROM then. One heck of a ROM that was. Later, in the span of months, so many developments came in for the device, CM11, CM12/12.1, MIUI, and so on. I was very happy to see that there are so many people working hard on providing us the very best experience on our phone. But, like most of the average mobile phone users, I used to download the ROM, install it and enjoy, nothing more than that.
Now, as the time has come for me to switch to a new phone, I am switching to Lenovo K3 Note. I have had digitizer issues with my Canvas 2 Colors and the battery back-up was a little on the poorer side. So, I'm finally giving my phone away to one of my friends and moving on. Although, I would've loved to experience the final, stable build of CM12.1. Thanks to all the devs that worked hard on that. @Al3XKOoL : Especially you, man!
Now that I'm going to be using a new phone, starting from the 28th of October as per Flipkart, I looked up the phone on xda. Unfortunately, there is no forum for the phone. I was a little disappointed, but even C2C did not have a forum a few months ago. So, I tried looking for ROMs, and I have to say, I was a little disappointed with the progress in new and variety of ROMs. I agree that it is a fairly new phone, but there are a lot of people who own that phone, so I was expecting better results. And another point that many people like me would be searching for ROMs.
The help I request from all the developers here is to teach me to develop ROMs and Porting ROMs. I am absolutely inexperienced here, but I'm eager to learn. I'm 17 years old and I am studying 12th grade at the moment. I would still love to learn about ROM development and Porting so that I can provide the people with some ROMs like you all have. Although, I will not be helping out the C2C family, I can start to help the K3 Note family in any way I can. I hope some developers are interested in having an acquaintance.
Please consider this a sincere request and if anyone can please help me learn, I would be very, very grateful to you. I know that I can't learn it overnight, and that is why I want a proper guidance.
If anyone is interested to help me learn about the things mentioned above, please contact me through a message.
Thank you and sorry for annoying you lot with a long post!
And I will be indebted forever to all the developers in the C2C community for giving me and all the C2C owners a pleasurable experience. Thank You!
Sorry for tagging you people, but I hope you don't mind and you people are the most recognized devs in the C2C community :

first of all thanks for our words..im still using my WIKO RAINBOW as my second phone..ive moved on to VODAFONE SMART ULTRA 6 and im testing MIUI 7 LOLLIPOP with a ported rom already that is booting and running with TWRP ..although is very buggy its ALPHA version still, that is nice..
for developers/porters whatever is not easy to teach someone..we have our work to do and that kind of knowledge we have, it took us a few years and at least some dead phones, hard bricks and a few other bad things that could happen to our phone..so my advice to you:
read
search
talk with other users
now and then ask for help when you need it, some users know a lot
you need time and patient..be aware that many times things will not go as you expect or wish..best of luck and keep following us in my blog and youtube..RAINBOW / MMX A120 C2C still is a good phone.:good:

Hey, thanks for taking time out to read my post and replying.
Nice to hear that you've been working on a different phone and rolling out new ROMs for that phone too!
Yes, I know that everyone have their own work, family and personal stuff and everyone are developing in their free time or as a hobby. I will be doing the same too as I have my studies as a bigger priority.
I understand it is not easy to teach anyone about developing, at least guiding is possible, right? I would be glad if you could guide me in what to read and where to be careful etc. stuff like that.
I already bricked my K3 note once and revived it somehow. I know it will not be an easy road or it is just as easy as downloading a ROM and flashing it in recovery, most of the users can do that. I know it is hard work, I will try to read, but there is so much knowledge on XDA alone that it will take me forever to read, understand and be able to implement. So, what I am asking is, if you could let me know on where to begin and in which direction to go after that, I would be indebted to you.
Again, Thank you for taking some time out, I know you have loads of work, and I hope I can be as good a developer as you someday!

There is a Chinese developer who has rolled out CM12.1, but the English translations are not complete, so there are some chinese fonts still left behind, and there are some bugs in that too. I would not recommend using that ROM for daily use till the bugs are sorted out and the full English support is included.
With some support, I was planning on compiling CM12.1 for the K3 note. I've noticed that major developments for this phone is on some Spanish and Russian websites and not on XDA. I was a little sad to see that, but hopefully, there are a lot of developments on XDA too!

SM-S820L Lollipop Update?

Is there any way to get Android Lollipop on the Galaxy Core Prime SM-S820L? I have read about custom ROM's but I still don't know much about them and can't find any for this model. If anyone has found or created a way to flash a custom ROM onto this device, please let me know.

I also own this device, and unfortunately there is very limited support in the custom Rom department. If there was to be a lollipop Rom, someone would either have to port one somehow, or build it from source. Given the development rate for this device, I don't predict it happening anytime soon, sorry to say.
not going to happen
i have been trying since february the answer i got from my carier was samsung is contracted not to support this device thats why that is so hard to find samsung told me to take the device to bestbuy to force update if they could probably irrelavent but maby it helps
SM-S820L Got the Shaft!
Yup! This seems to be the future for the SM-S820L, or lack of future I should say.
I too have the Samsung Galaxy Core Prime SM-S820L. I have spent lots of hours scouring the internet looking through every android related forum in hopes of eventually finding someone that is undertaking much needed programming to build a custom ROM for this CorePrime version.
If you are looking for a custom recovery to use. I can point you to my and others posts over at Needrom. The best I can offer is an unofficial TWRP release, but it DOES work! It does for myself at least and I am no Android Guru whatsoever.
I guess I am not allowed to post Links in any of my posts yet because I am still a NOOB on these forums. I'll PM you with some direction my friend!
I cannot take credit for coming up with any of that software. I simply rooted around long enough to compile a collection of tools and files that worked for me to modify the Recovery of my SM-S820L.
:good: Feel free to shoot me a Private Message on this site or to my personal Email....... [email protected]
I would love to help out as much as I can with modding your phone. Like I said, I'm not a proffesional but I have read up on the procedures used and been successful with my own Galaxy Core Prime:laugh:

Wrong SECTION. You should have posted this in Questions & Answers
It is probably almost impossible:
1 ) We need clear AOSP as a base because if not there will be so freaking much bugs to resolve that it is not worth it
2 ) MIUI require special porting way for diferent socs there are diferent sources for snapdragon, diferent for mediatek but did not see any for our kirin
3 ) It need a lot of testing reainstalling so there need to be someone who can live without his p9 Lite
4 ) There is needed someone who knows how linux works and someone who know good miui rom
5 ) Maybe it would be possible with AOSP as a base but we dont have it and it is hard to port clear aosp so will not even sit with this
6 ) You have stock EMUI which is similar you dont need MIUI
7 ) I dont have actually time to even put linux in virtual machine so wont do this
8 ) This thread is in wrong section so need to be moved to q&a but I think I answered you question
9 ) Even if it is possible you will not even try this because you have locked bootloader. So if you will unlock it to install rom so why not to unlock it now and build it on your own? Just learn how to do this. For me on my old phone it did get a week to have a booting rom. But there was clear AOSP. Here I dont know will be longer so go ahead and good luck
OK changed my mind. Will try to build based on cm13 but nothing to promise and dont know when will find some time so dont expect anything
Thank you for your post
