Good news, sound is working!

More than a half year after my first Lollipop build, finally I could fix the sound problem. I used some commits made by timduru and decatf and added my own changes.

The rom isn't stable yet, but the work is going on.

For those, who want to check it out... I will upload the rom in the evening.

I began to push the sources to github, so we can share improvements.

Looking forward!

Lollipop (pre Beta)

Hi guys, here is the link for my latest build.:

http://sourceforge.net/projects/lgo...M/cm-12-20150816-UNOFFICIAL-p990.zip/download

Don`t expect too much. There is progress, but not a stable build.

Now sound is working, I tested bluetooth with a speaker, which workes. No fast forward bug!

But the resources are very small because of some problems in the backround.

Remember: After first boot wait 2-3 minutes to give the system time to finish the work in backround. Then choose your language.

I think, the sim-card will be recognized, mine is broken, please post your results!

I hope, that some of you will have ideas to improve my code on github(www.github.com/gucky01)

Have a good week,

Hi Guys,

I'm unable install latest build (cm-12-20150816-UNOFFICIAL-p990) on new bootloader by using (CWM 6.0.2.5).Please find the attached error for the same.

If someone is able to install it successfully please let me know which CWM/TWRP are you using?
[LG Optimus 2x] Genie's:
You should install KK or LP with CWM 6.0.4.5 or higher, or TWRP 2.5.0.0 or higher.
[LG Optimus 2x] messi_007:
Hi All,

I tested the latest build of Lollipop.

First of all thanks and congrats to Gucky and whoever directly or indirectly helped for his excellent efforts to build this rom. This is amazing when u run android Lollipop on 5 years old device!!!

0. Please take back up of existing rom before installing new new build. (Note back up should be taken on latest recovery you will be using to install this rom i.e. CWM or TWRP so that u will be able to restore immediately)

1. This is pretty smooth rom I tested this for 3 hrs

2. SIM card is being detected and undetected ,currently unstable

3. There is no Google play ,can u pls include it in next build? We wont be able to install any app without it.

4. Internet is working fine whenever SIM is getting detected.

5. Bluetooth I couldn't test

Keep it up guys. wish you good luck!

[LG Optimus 2x] gucky01:
builds for 2x

Hi Messi,

I could build a rom based on the 12.1 code months ago. This one is more stable, but the camera issue is still present.

Parallel I tried a rom with Timburus sources and some combinations of both. In one build the camera error dissapeared in the log, but camera doesn`t work.

In my opinion, the main problem is the absence of good coders here. I uploaded my sources to github, but I don`t see anyone, who works on...

LG p990 is dead ????????????????

Without Tony p .......
[LG Optimus 2x] DJNoXD:
The problem with old phones (like the p990) is that the amount of time rises to get the new android version working.

Working doesn't mean bugfree. Removing the bugs needs additional amount of time.

And thats the big problem. Its fun to develop and get things working, but you will need the time.

So think you have a family (needs time), a job (needs time), your social live and your hobbies.

You have to set the priority.

Speaking for me: job needs very much time (since one year) and also my family needs time.

So very less time left for anything else.

The more people are working on it, the better is the chance to get something new.

The sources are there, so start working on it. :fingers-crossed:

As promised here my last build for our 2x. It`s based on CM-sources+Tonys device and vendor tree +modifications. It`s a 3.1 kernel rom for the new bootloader. For instructions look on the first page in this thread.

Big thanks goes to Timduru, who constructed many patches for the tf101, which I could use.:D

The rom isn`t stable yet. So, check it out just for fun. :) Perhaps someone can post the working and not working parts, logcats will help!

In the next days I will build another one with m1 kernel.

My sources on github: www.github.com/gucky01

Some work ist left here: I have to sync my frameworks/native and device tree + writing a local manifest, then evereything should be done. Feel free to use ist or give some comments!

Parallel I´m working on a aosp- based rom. This one should be quicker, we will see.

Yes but you need to also make some minor changes to the build script to make it fully work with mac as far as I can think back.

I suggest to use Ubuntu or a distro based on ubuntu since Unity sucks with multitasking. Try zorin os or gnome classic.

Guys I am going to participate soon in this project, first gotta finish some tests and then I will compile some personal builds for myself and try to get it working/to get a logcat. I wonder how android L will work with non neon devices:rolleyes:
[LG Optimus 2x] TheMysteryouse:
exp

Could you maybe explain me what ye all mean with ' non neon devices' ? i dont get it lol.U can participate at any time if you need our files, go ahead :D
[LG Optimus 2x] zerocoolriddler:
From Wikipedia:

"The Advanced SIMD extension (aka NEON or "MPE" Media Processing Engine) is a combined 64- and 128-bit SIMD instruction set that provides standardized acceleration for media and signal processing applications. NEON is included in all Cortex-A8 devices but is optional in Cortex-A9 devices.[59] NEON can execute MP3 audio decoding on CPUs running at 10 MHz and can run the GSM adaptive multi-rate (AMR) speech codec at no more than 13 MHz. It features a comprehensive instruction set, separate register files and independent execution hardware.[60] NEON supports 8-, 16-, 32- and 64-bit integer and single-precision (32-bit) floating-point data and SIMD operations for handling audio and video processing as well as graphics and gaming processing. In NEON, the SIMD supports up to 16 operations at the same time. The NEON hardware shares the same floating-point registers as used in VFP. Devices such as the ARM Cortex-A8 and Cortex-A9 support 128-bit vectors but will execute with 64 bits at a time,[56] whereas newer Cortex-A15 devices can execute 128 bits at a time."

Our Tegra-SoC doesn't support NEON. That's one Reason the O2X is not supported by CM anymore.
[LG Optimus 2x] TheMysteryouse:
Oh.....thats also the reason we dont have an official cm rom anymore...Thank you sir for the info c:

Wow

Its amazing how many people are working right now to make a lollipop rom.Me, gucky, Puri, Djn maybe , some others and now you.Its amazing to be honest. :)
[LG Optimus 2x] wulsic:
Ey guys, I will soon obtain the 2X, for how long I don't know but for now I suggest that we pick a device tree which we are going to use as a base for the lollipop tree so that if we got stuff working/fixed things that we could push our commits to the lollipop branch so that the future rom developers who are going to make custom L roms for the 2x won't have a too hard time.

I will look tomorrow already a bit in the device tree/setting up my own place to compile for the 2x and see which device tree and kernel source we could use the best to get a working lollipop. Kernel version is suggested to start at 3.0.x

I gotta scroll through the pages a bit, the last time I did something with the O2X was like 1.5-2years ago. Good old time.

Does somebody has any suggestions, like which device tree is the most stable/up to date?

Edit:

I guess we are going to use firtecy's kernel sourcecode or that from Pengus since they are 3.1.10 which is more recommended then using the old 2.6 kernel.

For android L. If we get it booting the it's an alpha, then we can still always change from kernel sourcecode but I suggest that we just use 3.1 despite the gyro/camera bug.

Also guys, look at other devices with Nvidia tegra2 like the galaxy tab 10.1 which also has android L booting, just so that we can also use commits for our beloved 2X.

The Epic penguin team will get it working just like the Hacked cm9 or cm10 long time ago..

Sorry for this long message, the unbrickable device just brings up lots of memories.
[LG Optimus 2x] tonyp:
Personally I don't see a real use in trying to "port" (as in: swap files of another ROM rather than to actually build it) a Lollipop ROM.

Swapping the binaries like [MENTION=5021221]gucky01[/MENTION] does might help to figure out which packages will need fixes, but a proper log should point to these issues, too.

At some point you'll definitely need to start compiling the ROM to make progress. Everything else is a bit pointless.

The reason the ported ROM doesn't work certainly isn't some banality like the TF101 having a navbar.

[MENTION=5403922]wulsic[/MENTION]: Here's my CM11 device tree which should be a good starting point to bring up Lollipop: https://github.com/tonyp/tonyp_device_lge_p990

It is the continuation of [MENTION=2330281]aremcee[/MENTION]'s old CM device tree, with all the additions of people like [MENTION=3783116]pengus77[/MENTION], [MENTION=5600347]hjunii[/MENTION], [MENTION=1200697]DJNoXD[/MENTION], myself and all the other people I didn't list.

Your best shot will be the work of [MENTION=3951330]timduru[/MENTION], who managed to compile a working ROM for the T2 TF101.

So the first point to go should be his device tree, which you can find here: https://github.com/timduru/device_asus_tf101/commits/katkiss-5.0

Then include his additions.

Here's his local manifest: https://github.com/timduru/local_manifests/blob/katkiss-5.0_GCC/katkiss.xml

But remember he's building on an AOSP base, so it isn't directly compatible to CM. Building AOSP would require even more changes for our device to work, as it's missing lots of backwards-compatibility stuff CM has.

I had an ASOP build ready ages ago, but that work is buried somewhere in my sources (feel free to dig through my sources at Github - but it's not really worth the time considering so much stuff has changed by now).

You'll definitely need to fix frameworks_av, surfaceflinger etc (stuff like this, you can also use the patches in my device tree by hjunii as orientation).
[LG Optimus 2x] tonyp:
Ha, 30 minutes of abusing Google have been worth spending: I finally found the commit I used back in the days to enable adb on a development build:

Allow ADB to be enabled by default via a config overlay on a per-device basis.

https://github.com/ChameleonOS/andr...mmit/3fa2c88407715cd298af6eeb792a06f7e322e81f

I couldn't remember where you had to enable it, this was the correct place.

Use that commit and add config_enableAdbByDefault=true to the overlay (alternatively you could enforce the "1" temporarily within UsbDeviceManager.java to have it always enabled).

I'm not 100% sure how it works with adb authentication, but you can just grab the *.pub files from your .android folder and push it to /data/misc/adb/adb_keys via the recovery to authenticate your computer.

Hi community,

it is a shame that there is no more developers working for this great phone. I just found out that someone got Android Nougat working on a Nokia Lumia 520 (http://xdaforums.com/windows-phone-8/general/nokia-lumia-520-booted-android-nougat-7-t3512011) with almost the same specs as our beloved LG P990: Dual Core and 512MB RAM... And multitasking is working too!

Is any developer out there willing to try this out? Maybe Nougat is a little bit easier to port than previous versions? Hope some would like to try this out! :D

Merry Christmas und a Happy New Year!
