HOW TO : UPDATE to 4.3 from STOCK 4.2.2 ( STOCK recovery, Locked/Unlocked Bootloader)

[Ivan Aldwin Cristobal]

This is the procedure I followed to Update to Stock 4.3.

Requirements:

1. 4.3 update file : Click here - JWR66V from JDQ39

2. MINI SDK package attached here : mini-sdk.zip

3. Windows PC (Win 7/8) I have not tried on windows XP or lower

4. Nexus 4 drivers installed on the PC

5. Ensure you have adequate battery life on the phone ( atleast 50%)



Steps to Install:

1. Unzip the contents of the mini SDK package to the root of your C drive

2. Move the 4.3 update file downloaded in step 1 to the mini SDK folder

3. Rename the update package to Update.zip (ensure that you can see the file extension in windows before renaming so that the file is named correctly)

4. Open command prompt on windows

5. Type in the command : cd C:\mini-sdk

6. Boot your phone in Fastboot mode and then go to recovery

7. In recovery select the option "apply update from ADB "

The screen will then show a message : Now send the package you want to apply to the device with ' adb sideload <filename>".....

8. Back on your PC type in the command : adb sideload update.zip

9. The phone will display certain messages and will update itself in the background

10. Wait till the update is complete and Enjoy 4.3


Notes:

1. You will NOT loose your data

2. This can be used only on STOCK recovery

3. It will work on UNLOCKED bootloader
