Download, for the first one, these files on your PC:
- CM 10.2 unofficial ROM zip
- Gapps for Jelly Bean zip.
Leave both of these packages unzipped and plug the smartphone to the notebook once the two files have been saved on the latter. Then it's high time you did the following: take the Gapps and the CM 10.2 zip files and move them to the SD card root of the Galaxy S2 I9100G. Then wait for this copy + paste task to end and unplug the handset from your laptop after that. After the device is turned off, you should enter it into Recovery Mode and then, in case you haven't done so for the pre-requisites, make that NANDroid back.
The latter task depends on whether your phone has TWRP or CWM Recovery. In case it has the former, creating a NANDroid backup should be done like this:
- press "Backup"
- choose what it is you want saved
- confirm.
Those of you whose handset has ClockworkMod Recovery instead, do as follows:
- choose Backup & Restore
- make a confirmation of this.
The Galaxy S2 I9100G has to receive a factory reset now. As mentioned above, the process depends on what custom recovery image your handset boasts. Should it run on TeamWin Recovery Project, then tap "Wipe", click on "Factory Reset" and then confirm. But if CWM Recovery is the phone's custom recovery image, you need to opt for Wipe Data/Factory Reset and then confirm.
To install CM 10.2 ROM text build on the phone, you need to, in case the device has TWRP, check out the next steps:
- tap "Install"
- find the CM 10.2 zip file
- slide a blue key to the right
- the installation has been confirmed.
For the version that sports the ClockworkMod Recovery, you must:
- opt for Install zip from SD card
- select Choose zip from SD card
- locate the zip file required for the upgrade
- confirm.
Then install the Gapps zip file by repeating the steps followed for the flashing of the CM 10.2. Once the tools have been flashed successfully, you can go back to the phone's recovery Menu and then reboot the device. Then access the firmware by going to your Google account; once there, enter the details you type in whenever you open it and wait for Home Screen to pop.
The ROM with which your phone came when you purchased it may be something you want to have back at some point. This is why we asked you to create a NANDroid backup. To have the old ROM restored, you have to use the backup file that comes with NANDroid. Then fully enjoy the Galaxy S2 I9100G in its restored state.
