[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
Download and Installation Instructions

PLEASE FOLLOW THE STEPS EXACTLY AND IN THAT ORDER, do not try to be cute and invent your own process, nothing good is come out of that. Also, the only recovery I have tested is CWM 6 from sk8, no other recovery has been tested, the update script depends on the recovery providing reliable execution of the commands. If you bootloop or FC after installation, it is not a good sign. I cannot help you debug that, the update script leaves a log file in /data/log, check for errors there.

Step 1) Make a Nandroid backup and better yet also TiBu if you need to restore apps.

Step 2) Did you do Step 1)???? Do it now, already.

Step 3) Make sure you downloaded the Full Wipe ROM and any add-ons or latest Stock theme or Embryo base theme updates (orange) or bloat. if you want the stock theme.

Step 4) Please make sure to check the md5sum's.

Step 5) Boot into recovery.

Step 6) Format /system (usually in mounts and storage menu option)

Step 7) Format /data

Step 8) wipe data and cache partition

Step 9) Did you do Step 6, 7, and 8? If not, STOP, do NOT proceed.

Step 10) Turn off Signature Verification. Select the Full Wipe ROM zip and flash.

Step 11) [OPTIONAL] If you want the Stock Theme, flash it now. Or, if there is a theme update package (orange), flash it now. NOTE: Flash only one of the themes.

Step 13) Good, now reboot and LET IT WAIT till everything is installed. Do NOT touch and mess around with any keys. Your installation went fine, if you see the bootanimation and then the touchkey lights up (dalvik cache being built) and then installing applications screen shows up. If the touchkey's don't light up you are hosed, bad flash, reattempt!! Same thing if the installing applications do not show up. If the above sequence of events do not happen, then your flash is borked, please look in the internal sdcard for the recovery log embryo-7-recovery.log, pastebin it.

Step 14) IMPORTANT Follow Any POST Installation stuff below.

Please do the following, after a full wipe installation. After the ROM boots:

1) Go to SuperSu and activate the app. (yes to update binary, Normal installation for the next prompt).

Please check the MD5SUM for all downloads on YOUR phone (not on the PC e.g).
