1º La Rom 4.2.2

 Cita:

Step 1) Turn OFF your mobile and go to Download Mode by pressing and holding the Volume Down + Home Buttons together for few seconds followed by Power button then proceed with volume up. (For some phones, when you see the construction Android robot and a triangle, press Power again to confirm to enter into Download Mode).

Step 2) Now open ODIN on your PC and connect your Galaxy SII Plus GT-I9105/P to your computer.

Step 3) Once your phone is successfully connected to your PC, the ID:COM box on ODIN will turn blue and will show the COM port number.

Step 4) unzip the downlowded file (from second post), u will get a Home.tar file.

Step 5) click on pda in odin (if odin 3.09 choose AP) and choose the file "xxxx.tar.md5"

Step 6) check "Auto Reboot" and "F. Reset Time" options and make sure that "Re-Partition" is unchecked

!!!!DO NOT CHECK "Nand Erase All" IN ANY WAY!!!!

Step 7) Click on Start button in ODIN window to start the installation process. The process will take few minutes to complete.

DO NOT UNPLUG USB CABLE WHILE EXECUTING THE PROCESS, YOU MAY BRICK YOUR PHONE!

Step 8) When the installation is completed, you read a "Pass". your phone will restart (first boot will take a longer time so don't panic)

2º Paso de la instalacion es poner el nuevo Recovery:
En odin, quitamos, sin repartition, En PDA ponemos el "CWM4.2.2.tar.md5" y lo hacemos.

3º Metemos el archivo root en el movil.

4º Apagamos e iniciamos en modo recovery ( Volumen Arriba + Home + Power )

5º Install zip... y buscamos el archivo "root.zip" que descargamos


Y listo
