|26 September 2013||Updated the steps for entering download mode so that Odin can detect your phone.|
I’ve always wanted to update my Samsung Galaxy Wonder to Android Jelly Bean; lately my cellphone became quite slow (especially after the latest upgrades to Android 2.3 from Samsung) and I always wanted to install Chrome and Google Keep that both require Android 4. Samsung does not provide any official release of Android 4, so I decided to go for a custom ROM. In particular, I’m using Android Jelly Bean, 4.2.2, CyanogenMod 10.1 ALPHA (Build 7).
I had quite a hard time to understand how to install it; basically because I had never installed a custom ROM. Moreover, the instructions to do that can be found on the web but I never found a complete tutorial that shows the procedure from the very start: they all assume that you have already done previous steps.
Then, I decided to write a complete tutorial (this is based on Windows). This assumes you have an external sdcard on the phone.
The update will wipe out all your data, so make sure you backup them first. Proceed at your own risk. You will also lose Samsung warranty.
PLEASE, if you have problems with this custom ROM, DO NOT post comments to this blog post: use the official discussion forum thread.
Make sure you read the whole tutorial first, before proceeding.
Disclaimer: All the tools, mods or ROMs mentioned below belong to their respective owners/developers. I am not to be held responsible if you damage or brick your device.
Make sure you can connect your Android phone with the computer. If not, install the USB drivers for Samsung Galaxy W properly. The easiest way is to install Samsung Kies.
Install ClockworkMod recovery using Odin
Extract the odin Multi_Downloader_v4.43.exe file and run it.
- enable “One Package” in options
- Select the Ancora.ops file,
- load the md5 file with the “One Package” button
- turn off phone,
- hold Volume Down + Home + Power Button for a while till the phone turns on.
- the phone will turn on and black porn show some screen,
- plug in usb cable
- press Volume Up
At this point Odin should detect the connected phone
Wait for the download to finish (see Odin)
Create a backup of the current image
Turn on the phone in the Recovery Mode: hold Volume Up + Home + Power Button for a while till the phone turns on (Note: this time it is “Volume Up”, not “Volume Down”). Release power button as soon as samsung logo appears and hold your volume up button + home button until clockworkmod recovery appears on the screen
- Volume buttons to move in the menu
- Home button to mobile porn select a menu
- Power button to go back
Select “backup and restore” and then “backup to external sdcard”:
You may want to store a copy of the backup in your computer hard disk; just connect the phone with USB, and navigate to the directory where the backup was saved on the phone sdcard:
Put these files in the root folder of your external SD card (you can turn on the phone as usual and connect it via USB for that, or copy these files from the computer using an external card reader).
When the copy finished, disconnect the phone and turn it off.
Switch ON the phone in the Recovery Mode: pressing and holding Volume Up + Home + Power buttons together.
Now wipe data and cache selecting the following commands (and wait for them to complete)
- Select “wipe data/factory reset”
- Select “wipe cache partition”
- Select “advanced” and then select “wipe dalvik cache”
Select “install zip from sdcard” and choose the zip file containing the OS (in this case it is cm-10.1-20130611-EXPERIMENTAL-ancora-alpha7.zip) from the root of the SD card (where you previously copied it).
Now do the same for the google apps zip file: select “install zip from sdcard” and choose the zip file containing the OS (in this case it is gapps-jb-20130301-signed.zip) from the root of the SD card.
Now you’re ready to reboot into the new system from the main menu!
NOTE: Your Phone will boot now and it might take about 5 minutes to boot on your first time. So, please wait.
If everything went fine, you should see the new logo
Note: as for me, this procedure started with an error message saying that the vocal synthesis engine crashed, but I simply ignored the message and went on.
After you inserted your Google account, the phone should be ready; at this point, if you selected an Internet connection, all the applications you had previously installed from Google Play should be installed automatically… it took about an hour in my case.
The system seems rather stable and surely more responsive than before!
Battery usage seems to have increased, especially when connected with WIFI.
All in all, I’m very happy of the new system.
These are all the links where I found the software and information I based this tutorial on.
