TG P990 ICS V30A - Stable - Rom and Advanced Kernel
BY TOPOGIGI



FEATURES:
Quote:

- Based on ICS 28G Nvflash 1st edition from Stefan Guendhoer
- Updated Gapps in /system/app
- Updated Meteo Widget
- Updated Polaris Office
- Advanced 1.4 OC/UV kernel recompiled from SU660 LG source for P990
- EXT4 filesystem for /system, /data and /cache partitions
- /system/etc/init.d support
- CIFS support
- TUN support
- Tweaked Deadline scheduler
- Sio scheduler (default in this rom)
- Supercharged via build.prop and init.rc (Supercharger is named "v6sc" in /system/xbin)
- KAK (Kick Ass Kernelizer) included in /system/xbin (named kak) and in init.d
- OC up to 1408 Mhz (via SETCPU, Antutu CPU Master or Pimp my CPU)
- UV (via Pimp my CPU or others)
- Optimized mount points with timed commits and noauto_da_alloc option
- Hotplug CPU governor (finally the second CPU goes to sleep when it's not needed)
- ZRAM included with 75MB swap size
- SuperSU by Chainfire is included
- Busybox (1.19.3) is included in /system/xbin

Long story short, this is a follow-up to the excellent work Stefan did with his ICS28G release. I decided to post this rom some days before my original intentions, because Stefan's thread is now closed and there will be no follow-up. Besides that, LG is making us wait until the end of the world before releasing their official update and this will make me work twice at least (now and when the proper kernel sources will be released). That's all.

Feedbacks are welcome.

DISCLAIMER: This ROM comes with NO warranty. If you brick your phone, don't blame me, I'm only experimenting with my phone and sharing the results with you, mates!



INSTALLATION INSTRUCTIONS:
Quote:

- BACKUP BACKUP BACKUP your actual rom and your data before installing anything!!!!!!
- Follow accurately Stefan's instructions in his original thread: this is a rom meant to be installed with nvflash!
- Reboot your device at the end of the process, go to system/xbin with a terminal emulator and type "su" and "v6sc" for checking the V6Supercharger functionalities
- Enjoy your new rom.

P.S. This rom wipes completely your phone (see changelog for exceptions),Backup all your data before installing this Rom!!!

KNOWN ISSUES:
Quote:

- Overclocking is highly unstable in this rom. I managed to OC my device for a few minutes but it hangs in a while. So, OC is for now enabled only for TESTING PURPOSES! Keep that in mind and do not complain about it until I will manage to make it stabler. (All OC issues are solved flashing SP2: overclock is really stable on my device @ 1.3 Ghz)

RECOMMENDED DOWNLOADS/SERVICE PACKS:
Quote:

- TG ICS28G SERVICE PACK 2 - download from here: http://depositfiles.com/files/4bza0mnh3
It's a CWM flashable .zip (flash it via recovery) with the following changelog:

- Stable overclock @ 1.3 Ghz (1.408 max OC for lucky people with an elite tegra chip)
- Increased swappiness (65) and zram (80Mb)
- 128 Mb ramhack thanks to wkpark's patch and suggestions.

Good luck!

DOWNLOAD:
Quote:

1.0 - Full ROM with experimental kernel (1.5 Ghz) with EXT4 partitions http://depositfiles.com/files/99led00ho
1.1 - Full ROM (CWM flashable) with stable SP2 OC kernel (1.4 Ghz) with EXT4 partitions rebased on v30a LG release http://depositfiles.com/files/iyl2urjxk

__________________
CHANGELOG:
Quote:

1.0 Initial Release - Flash with nvflash [OBSOLETE - USEFUL ONLY FOR PEOPLE COMING FROM OTHER ROMS/OLD BOOTLOADER/DIFFERENT PARTITION SCHEMES]
1.1 Flash with CWM - Entirely rebased on new v30a LG leaked release - Fully deodexed rom - Raised zram to 90 mb - Removed LG task manager - Added Gmail 4.2 with pinch to zoom in /data/app/- Added Jackpal's Terminal Emulator in /data/app[ACTUAL]


NOTES and KERNEL SOURCE:
Quote:

- https://github.com/Topogigi/LGE-Kernel-Star-ICS
I need time to comment out the source for every single change I made. So I committed the source AS-IS for other developers to immediately take advantage of an already patched base, ready for further commits. I will add comments to the source ASAP
- People coming from other roms are strongly advised to firstly flash the v28g nvflash package (1.0 rom nvflash based) and THEN upgrade to the following releases


CREDITS:
Quote:

- The entire CM team and AREMCEE in particular for his kernel repository. Without his github commits I would have not been able to recompile the sources
- Zeppelinrox for V6SuperCharger and Kick Ass Kernelizer
- wkpark and ibladesi for OC/UV code and ramhack solution
- Stefan Guendhoer for providing the base rom I reworked
- Faux 123 for the tweaks I applied to the deadline scheduler
- LG for providing us a leaked rom ?????? Am I just crazy ?????
....and many others that helped sharing their ideas and work for free.

ROM is uploading now (37% at the time being).

In the meanwhile, I drop some notes and some thoughts about it:

1) I use this rom from last week without any issue (besides overclocking) ad I must admit that even with the recompiled kernel I noticed no issue. Battery life is quite good compared to CM7.
2) The kernel is the same that AREMCEE used for his CM10 and the issues I noticed there are not present here. I mean I did not encounter the in call audio bug nor the Bluetooth always disconnecting issues here. So, I think that the old bootloader has a role in these bugs (the kernel is not the guilty part).
3) Overclocking: this is a real mistery for me: on other devices the same code works a charm: here you can't achive a stable OC even at 1.2 Ghz. Please help me to discover if this behaviour is limited to my own device. Try to OC gradually and report your results. The rom will always boot at 1.0Ghz, so no risk to brick it!
4) ZRAM really helps in making device snappier, so you can assume that LG did finally a good work and all the lags you can experiment are due to RAM constraints.

Let me know....

EDit: yes OC is little flaky right now but we should be coming to stable point when more people work on it.

And old bootloader is not related to in-call audio bug, it will appear after 3-4 days. But its not always the case, that issue is not traceable. Bluetooth fix was simple and it would not be in your kernel if you are not using cyanogenmo_p990_defconfig

It's nice to see you back

Especially, because of keeping fight up between devs and LG code

That's the way I like to develop. Sharing code (very well commented code) is the way to go IMHO. Cooperation is the key to success.

But.......I will miss Stefan in any case (even if my personal line of thought is nearer to yours than Stefan's one). Devs are rare stuff for a device that's slowly dying, and if I can put a good word in this fuss, try to find a good compromise with him, my friend

Welcome Back Topo

I am happy that we have the opportunity to try something new from your factory.
Topo Nostaligia was great as a return to the past, so now let's move into the future with the new Topo ICS
