First off Guys you need to install using Clockwork Recovery. This is no different then installing any other rom.

It is Jellybean 4.1.1.

Update: I will add a 15 Toggle Mod and Build Fix that will include a my original reworked siii framework and systemui from my original 1.2 release before I was going to release the LJ3 version. This should fix up some issues you guys are having with the percentage and give you back your 15 toggle mod as well.

Multiview: Since I am using the Gnote II's framework and SysUI in this build I redid the Multiview zips to include the Gnote II's Multiview instead of my modded version that I had made. This version is still a work in process. If you are having a problem flashing it, extract it and use root browser or root explorer to move the files to their proper location and set the permission as rw-r-r. This is still a work in process and does not fully function as it will cause the phone to crash due to issues with height restraints, the wrong keyboard (as the gnote ii keyboard does not work on the siii) and carousel.

Full Wipe? For best results I recommend a full wipe on this rom as many things have been changed since 1.1 and it may be a conflict it you do not do a Full wipe.

Prompt of Just Once or Phone: Yes this should say Just Once or Always and if you click Phone it act's as Just Once and not Always. However if you click Just Once it will Act as Always and Remember your choice. I am working on fixing this currently by renaming it. It is a result of the Gnote II framework-res.apk and is being worked on. However it does not affect the roms function if you remember what the difference is and you can always set the default app in applications or forget the default app.

Unfortunately, the process, %1$s has stopped - If you are getting this message you probably didn't install the rom properly and should do a clean install using clockwork recovery. However these messages are due to the Gnote II's framework and SystemUI. If you are running a specific program and this message pops up it is most likely due to the size (height and width) of the application and you can attempt to switch the application with the serenity 1.1 version of the app or a s iii version to fix. However through testing everything has been resolved I recommend a clean install using clockwork recovery.

Wifi Tether - Does work if you have an AT&T plan.

I read about a keyboard lag and battery drain from one use - the keyboard may have a little lag but if you turn you animations to .5x there is no lag. also the thermal settings start at the max cpu voltage for the cpu and then brings the cpu down way down and records the stages. the battery will be better after 1 days of use. if your phone is hot is hot at first it is probably because it's at the max cpu voltage and then brings it down. wait a day and its fine.

Serenity 1.1 theme was made by me and it's in the UpdateMe App called DGGreyAOSPTheme

UpdateMe is not My App I Can't Help It If It Crashes
