[AT&T Samsung Galaxy S II SGH-I777] Misterjunky:
HOW TO

If you plan on flashing a custom rom you will not need to root your phone because all of the custom

roms here in XDA forums are pre-rooted.

Here is the best and easiest way to flash/install a custom rom and backup your original stock rom.

First you need to install the Samsung USB drivers into windows.

(Be sure to use the original Samsung USB cable for trouble-free operation)

Here is the link for the Samsung Unified USB Driver: http://api.viglink.com/api/click?for...13196871580881

After installing the usb driver above restart windows.

Now is a good time to download a custom rom of your choice, there are about 5 or 6 you can choose from.

I would suggest to download the "UnNamed" custom rom which can be found here: update-unnamed-v1.1.0-full.zip

It is currently the best and most reliable full featured custom rom you can find for our i777 phone.

After you have downloaded a custom rom you need to copy it to your phone's internal sdcard.

To copy the rom zipfile to your phone you need to go into the settings of the phone:

settings>applications>development>usb debugging and make sure that the "USB debugging" is disabled.

Connect the usb cable from computer to the phone and open "Computer" from the start menu in windows &

there you will find a "SGH-I777" drive icon.

Open it and you will see 2 icons, PHONE and CARD, copy the custom rom zipfile you downloaded into the

PHONE drive. (you will only see CARD if you have an external sdcard in the phone)

Now you need to download these two files below.

SGH-I777_ClockworkMod-Recovery_5.0.2.3.tar kernel: http://www.multiupload.com/QQKN7NJAFT

Odin3_v1.83.exe Windows Executable: http://hotfile.com/get/116095613/4eaf8fc0/650871c/Odin3_v1.83.exe

Copy both of these files into a new folder on your desktop.

Open Odin3 in your new folder & select the PDA button & select the "SGH-I777_ClockworkMod-Recovery_5.0.2.3.tar" file.

Once this is done press the volume up & volume down buttons at the same time & hold them pressed

until you plug the usb cable from computer to the phone & you see the triangle on the phone's screen

and the "COM:XX" box in Odin3 light up yellow.

Then click the START button in Odin3 to start the kernel flash.

After successfully flashing you will see the blue CWM Recovery menu of options.

Select "Reboot System" from the menu.

After the phone reboots go back to settings and enable the usb debugging & power down the phone.

Now press & hold both volume buttons & press and hold the power button at the same time until you

see the SAMSUNG text on screen then let go of power button first then let go of the volume buttons.

Wait for the blue CWM menu then select "backup/recovery" then select "backup".

The phone will start backing up your stock rom at this point.

Once it gets done backing up your stock rom you can flash the custom rom.

To flash your custom rom select "Wipe data/Factory reset" from the menu.

Then select "Install zip from sdcard" & select the custom rom zipfile which

you have copied to your phone.

Once it gets done flashing & installing select "reboot system".

Using the blue clockworkmod recovery menu:

HOME softkey = selects.

BACK softkey = go back.

Volume Up/Volume Down = scroll up & down.

Now you are ready to use the phone. (at last!!!) :)

P.S. The reason I made these instructions so detailed is so even a NOOB can understand it! :)

Remember if a NOOB can understand this then ANYONE can! - (that means you!)
