[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
STANDARD DISCLAIMER
​

You are installing this ROM at your own risk. I am not responsible if you brick or anything. This is my daily driver, it has given me excellent battery life (actually goes to deep sleep).

THIS IS AT&T Skyrocket ONLY. Since the Kernel is included in this ROM and is cooked for AT&T only.

ChangeLog:

04/14/2012: Embryo 1.1 - Update

* Added call recording. (removed, Add Call button)

* Added El Librator 15toggle blue theme. (thanks El Liberator, you can thank him here).

* removed couple of bloat items

* Incorporated all patches from 1.0 onwards.

- Blue Circle battery.

- Autocorrect dictionary pack added.

Updates:

08APR2012: Upon request, providing the Circle Battery Mod, as a separate CWM zip. Note: this goes on top of the Embryo-1.0 base.

Introduction:

This ROM is my daily driver. I have deodexed ONE file at a time with the only bootclasspath required for each APK, yes I am a little bit anal about these things. No Kitchen or random dump everything in the classpath and deodex.

This is completely debloated. Purged with care and testing. If you need any app missing let me know I will give you the APK.

This is a basically *my* ROM, please no ETA. I do this to customize android to my liking. This is NOT themed, it is as stock as you can get.

Features:

Installation (For Update)

For updates please make sure, you are on Embryo-1.0 base.

* Place the update zip on SD Card.

* boot into CWM recovery

* Wipe Cache.

* Advanced -> Wipe Dalvik Cache

* Choose zip from sdcard.

* select the update file and flash.

* please let it settle, as it would need to rebuild the cache.

Installation (For Full Wipe)

This is important, please follow the instructions carefully. Also, you need the UCALC4 modems, if you don't have it, let me know I will upload it, download link in the end.

Backup:

Make sure you back up your data. I typically use TiBu, to move from ROM to ROM. Just backup "user" apps do NOT attempt to restore system app or data.

Prep:

Make sure you copied the rom and if necessary the modem into your SD card (internal or external, as the touch recovery can show both).

Install Procedure:

Make an Nandroid backup, in case you want to revert.

Go into Clockword Recovery. I personally use this ClockworkMod Touch 5.5.0.4.

Wipe data/cache partition (complete the action by selecting the Yes row)

Go into Mounts and Storage -> Select Format /system (complete the action, by selecting Yes row)

Did you WIPE Data/Cache and Format System as detailed in Step 2), 3) and 4). Please do it.

Did you really do Step 2) 3) and 4)?? If not please do it!!

The reason I am emphasizing Step 2),3) and 4) is because, the update script will NOT do that for you. I have intentionally not incorporated into it, as I found the format command to be unreliable, in the recoveries I have encountered so far. But, in the touch recovery it works flawlessly when executed from the CWM Menu.

Now, select the ZIP you downloaded and go through the install.

Enjoy!! the super fast and smooth ROM.
