from GB to ICS

INSTRUCTIONS FOR FLASHING ICS FROM PREVIOUS GB ROM

If you are not on hboot 1.23 or higher, start from step 1, if you are, go straight to step 10

1.- Make sure your battery is 100% charged as flashing will wipe battery stats

2.- It is highly recommended (but not mandatory) to have SuperCID, if you want it, go to my FAQs, the procedure to get it is in there.

3.- Make sure you have downloaded HBOOT 1.23. We will flash HBOOT 1.27 later. IF YOU FLASH HBOOT 1.27 BEFORE ICS ROM, YOU WILL GO INTO A BOOT LOOP BECAUSE YOU ARE STILL ON GB. YOU WILL HAVE TO REMOVE YOUR BATTERY, (after pulling out your battery, you will have to extract your SD card, mount it in a reader and delete PG58IMG for hboot 1.27, save PG58IMG for hboot 1.23, get your SD card back to your phone, battery too, close your back cover, and press power button and volume down hard key until boot loader screen appears and flash hboot 1.23)

4.- Copy the file PG58IMG for hboot 1.23 into your SD card root

5.- Long press the power button to get the restart menu, then select restart, then bootloader

6.- With volume down key, select the bootloader option and confirm by pressing power button

7.- Your phone will ask you to update, confirm this by pressing the volume up key

8.- Let it finish; your phone will turn off your screen for a few seconds. Do not worry, it is working, (It will boot twice.) When your screen comes back, it will finish flashing.

9.- When the message update complete appears, press the power button to reset.

10.- When your phone gets back to the lock screen. Delete PG58IMG (hboot 1.23) from your SD card, and prepare your SD card for clean install.

11.- To prepare your SD card for clean install, delete everything on your SD card but personal files. (Music, pictures, personal documents and movies.) If you want to restore your apps from Titanium Backup, you can do it without restoring data. If that doesn’t work, just go to settings>applications>managed applications; Delete data, cache, as for the chosen app, and download it again from the market.

12.- Copy the zip file for the ICS ROM in SD card root, then long press the power button for the restart menu. Select restart and choose RECOVERY.

13.- Once in RECOVERY, select “install zip from SD card”, then select “choose zip file from SD card.”

14.- Now select the ICS zip file to start flashing, you will be asked to confirm the new installation, select “yes”

15.- After doing this, you will be asked whether to perform a clean install or not. As this is the first time flashing ICS ROM, select “Yes.”

16.- Now you will be asked to select the kernel of your preference, select the one you want and let it continue.

17.- When it is done, it will let you know. Go back to main menu and reboot phone.

18.- It will take a while, maybe 5 to 10 minutes until you get the lockscreen for the first time, don’t worry, it is normal. When you get the lockscreen, leave it there for 5 minutes, the ROM is starting your wizard setup.

19.- (IMPORTANT) When unlocking, you will see the option for setting your google account, skip it by pressing your back arrow key

20.- Set everything you need and get your wizard setup done but DO NOT SET UP ANY ACCOUNTS YET. When your phone finishes with this, go to settings, scroll down to “Security” and check the box for unknown sources.

21.- Go back and reset your phone. Now set up all your accounts.

22.- Now, if you want to flash hboot 1.27 repeat steps 1 to 9 and you are done.

By flashing hboot 1.27, you will get latest RIL and radio for your phone
