My mission: hack the tablet Google Nexus 7 with Jelly Bean 4.2 installed to *upgrade* to CM10
Location: http://khonggiancongdong.org/
Results: MISSION COMPLETED.
Steps:
- Enable USB debugging mode: By tapping on “Build number” seven times, you have unlocked USB debugging mode on Android 4.2 and higher. You can now enable/disable it whenever you desire by going to “Settings” -> “Developer Options” -> “Debugging” ->” USB debugging”.
- Download softwares:
- ALREADY downloaded CM10 Nightlybuild 20121123 yesterday night.
- NOT download the Google apps for Jelly Bean 4.1.2 (the device currently running JB 4.2)
- Download ClockworkMod 6.0.1.9 for grouper (my device)
- PUSH the software to device’s sdcard:
- sudo ./adb push ~/Downloads/cm-10-20121123-NIGHTLY-grouper.zip /sdcard/
- Unlock the bootloader
- Reboot to bootloader: sudo ./adb reboot bootloader
- Unlock the bootloader: sudo ./fastboot oem unlock (then select YES to unlock)
- Install Recovery software
- I chose ClockworkMod (NOT touch version): sudo ./fastboot flash recovery ~/Downloads/recovery-clockwork-6.0.1.9-grouper.img
- Install Cyanogenmod 10 Nightlies and Google apps
- Select the option to Wipe data/factory reset.
- Then go to “Install zip from sdcard”; “Choose zip from sdcard”
- First, select your Cyanogenmod 10 Nightlies.zip
- Then, select your Google Apps.zip (I have to BACK to download and push/upload it to device’s sdcard)
That’s ALL 😉
Then it would reinstall all your recent apps automatically.
However, I do not know how to resync all app’s settings :). That would be an interesting open issue for next hacks.
