Recently I found out in the bq readers website that the Android 4.1 Jelly Bean firmware was available for my bq Pascal 2 and decided to upgrade it. According to the instructions on the bq website it should be very straightforward process: copy the “.img” file to the root of the internal memory, reboot the tablet and choose the update option that would show up. However, the process for Android 4.1 Jelly Bean is a little different, but it’s still an easy thing to do.
The bad news is that you have to use Micro$oft Window$ to upgrade it, since the application that uploads the new firmware only works on Window$ :\ . You might try running it using Wine, but I wouldn’t recommend it since I think it’s too risky and you may end up with a bricked tablet in case something goes wrong. Fortunately, I found a video from bq readers on youtube that describes the process (see below). To upgrade the firmware you’ll need a micro USB cable. Here’s the process:
- Download the image from the bq readers website or by clicking here;
- Backup everything that you have in your tablet. Otherwise everything will be lost.
- Make sure your tablet is connected to the power supply or with the battery fully charged. You don’t want it to run out of power in the middle of a firmware upgrade;
- Turn off your tablet;
- Connect your tablet to your computer using the micro USB cable;
- Press the “Volume Down” button and then, using a thin paper clip, press the “Reset” button. Hold it for 10 seconds, release the “Reset” button, wait two more seconds and release the “Volume Down” button. Window$ will begin installing the necessary drivers. If Window$ can’t find them, extract the files contained in the .rar file download in step 1, open the device manager and install the drivers manually (the video below shows this step in detail). Make sure you install the correct drivers according to your computer architecture (32 or 64 bits);
- Go the the folder containing the extracted files and run the RK29update.exe application;
- Tick the loader checkbox and click the “Format” button;
- Finally, click on the “Update” button and wait until it finishes updating. In a few minutes your tablet should boot the new Android 4.1 Jelly Bean! 🙂

Simple and easy, isn’t it? 🙂
Take care! 🙂
