Welcome to SentinelROM for Samsung Galaxy SII (International Version -i9100 ONLY). Compiled from modded CM10.2 source using the Linaro toolchain for extreme performance. Android 4.3
This is one of the most popular ROMs for Nexus 10, Nexus 7, Nexus 4 and HTC One X, SGS3, SGNII and today I'm happy to release it for the SGSII community.

Read what people have to say about SentinelROM.



This ROM is compiled from CyanogenMod 10.2 with all the features you get in a CM10.2 ROM, plus the following features.
  • Compiled with Linaro 4.8 toolchain for extreme performance
  • Increased volume (not quiet like most CM based ROMs)
  • Zip Aligned
  • Compiled from latest CyanogenMod 10.2 source by me, not a 'cooked ROM'.
  • LMT Pie Controls
  • OTA Updates supported
  • Improved Web Browsing performance
  • Improved 3D gaming performance
  • Amazing battery life
  • Additional theming and UI customisation
  • FAST support via this page and our Facebook Page
  • A free copy of my music player app
________________________




This ROM has been built to enhance the CyanogenMod 10.2 experience, with faster gaming and web browsing performance (no choppyness in Chrome too!) and best of all, extreme battery life.

It's designed to be an excellent starting place for people who want to add their own MODs and tweaks, rather than forcing people to use the included ones. Think of it like buying a quality new car, optimized to do everything it does well, and giving you the freedom to modify the hell out of it if you want to. :)

Countless hours have been spent making tweaks to settings to squeeze the most performance I can find out of this ROM while still providing excellent battery life and without the dangers of overclocking and kernel level tweaking.

I compile this ROM and Kernel from the latest CyanogenMod source code, add my various tweaks and adjustments, then test for stability, so you get all the benefits of CyanogenMod 10.2, plus my tweaks and extras, all without the instability and inconvenience of flashing CyanogenMod nightlies (which are not designed specifically for the SGS2 like my ROM is).

The kernel source is available from the CyanogenMod's GitHub.

None that I am aware of. please report any bugs ASAP.

If installing for the first time:

To install this ROM you will need to have an unlocked bootloader and a custom Recovery such as TWRP or ClockWorkMod installed (personally I recommend TWRP, I have had issues with restoring backups using CWM).

  1. Copy the downloaded SentinelROM zip to your Internal Storage.
  2. Boot into your custom recovery
  3. Back up your stock ROM
  4. Enter custom recovery
  5. Factory Reset and wipe Cache and Dalvik Cache
  6. Wipe your system partition
  7. It's preferable to wipe your data partition if coming from a non CM10.1 based ROM
  8. Install the ROM
  9. Install GAPPS
  10. Reboot, the first boot can take up to 5 minutes.

Important: After installation you will be asked if you want to turn on CyanogenMod Statistics, please leave it off as this is an unofficial/modified build.

Note: Use of titanium backup to restore apps and data from another ROM is not recommended, and is the source of 90% of user issues, especially when it comes to battery life. Do so at your own risk.




You may flash other kernels as you wish via recovery. Remember to also flash the correct libraries for any 3rd party kernels. Instructions will be given by the Kernel author. NOTE: Updating the ROM via OTA will also overwrite any custom Kernels you have installed.
________________________




The following mods are developed by 3rd parties and have been tested by SentinelROM Users.

I can not offer support for these mods, or comment on their affect on performance or battery life. Use at your own risk.

MegaBassBeats! - by DeHuMaNiZeD

exFAT SD Card support - by HMkX2

How did you achieve extreme battery??? I'm curious. :)
It's a combination of many things.

*All the applications are optimized and tested. I don't include anything that causes wakelocks.
*Carefully selected tweaks and mods.
*Theres a few tweaks to Wi-Fi settings, etc to minimise battery usage.
*Optimised kernel.
*Compiled from source rather than cooked, so all the code is pure.

I'm looking forward to some feedback. HTC One X users are getting up to 4 days battery life with it, and similar on SGS3.

Hey mate! I'm glad new devs are working for our "old" device! Welcome in SgsII world! :D

I'm downloading the rom right now. Give me a couple of ours and I'll give you my first impressions! :)

Looking forward to it! As always, make sure you do a Nandroid backup before installing. And also do a full system wipe too.
Yes mate,don't worry: I don't like dirty flashes. The full wipe is my way! :D

PS. At the moment I'm on latest cm10.1 nightly(stock kernel). I think I'll write 2-3 lines about differences if helps ;)

Sounds good mate! For the most part, the available settings and options are the same as CM10.1 nightlies, with the exception of a few things like enhanced pie controls. The main difference is the performance, stability and battery life.

The ROM is designed to be an excellent starting place for people who want to add their own MODs and tweaks, rather than forcing people to use the included ones. Think of it like buying a quality new car, optimised to do everything ti does well, and giving you the freedom to modify the hell out of it if you want to.

I'd love to stick around and see some feedback, but its midnight and I have massive day at work tomorrow, so I'll check in in the morning and see how it's all going.

Have fun guys!
Last post before you sleep! :)

The rom is good, fast, and has no problems(at least for my usage). It's very similar to cm10.1 in speed and visuals.

Nothing to blame, it's stable and i'm ready to try it for a couple of days!

I set the cpu like this: Ondemand - Noop. 200-1200mhz. Screen off profile with 200-500mhz. Tomorrow's evening we'll talk about battery life ;)

Good night! :)

zzzzzzzzzzzzzzz*LIKE*zzzzzzzzzzzz

BTW: I'm very keen for your feedback on LCD density. I left it at stock CM10.1 which is 240DPI for the initial release, but I'm open to suggestions! Once we have some more SGSII fans on Facebook I'll put up a poll so I don't pollute this thread :)
