Asus Transformer Pad Infinity TF300T users got an official upgrade of its OS to Jelly Bean, over a month ago, and it did not apply to the bigger and more powerful Transformer Pad Infinity TF700, until now. It is possible, following the instructions below, to get cozy with the Jelly Bean on the TF700. However, for a start, there are limitation to brightness and PPI issues reported by many and if it affects you, remember that you are warned.
These instructions work for a device that has an unlocked Boot loader. If you miss one, use the ASUS Unlock Tool to do it. The copy meant for Ice Cream Sandwich will work well with Jelly Bean. Here are the steps :-
- Switch off the tablet.
- Use your computer to download the TWRP blob file for TF700 and rename the file to “twrp.blob”.
- Transfer the blob file (the one you renamed) to the platform tools folder available at the location where you installed android-sdk in your computer.
- Connect the tablet with your computer using a USB cable
- Boot directly into Fastboot mode (you can do this by holding the Volume Down + Power button for 5 seconds).
- Select recovery mode when a message appears, by pressing the Volume Down key twice and Volume Up once, within the five seconds provided.
- Press the right keyboard shift and select platform-tools folder. Choose to open command window here and when it the command window opens, type the following prompt:
- fastboot-i 0x0B05 flash recovery twrp.blob
- This will copy the firmware into the device and install it.
- When it completes tell the tablet to reboot by entering the following prompt:
- fastboot-i 0x0B05 reboot
Your device will start with the Jelly Bean 4.1.1 interface, and you are good to go.
These instructions to custom upgrade the Asus Transformer Infinity TF700 came out from an effort by the XDA forum members who did not like the fact that an older device in the Asus tablet range was getting an update, while the more capable one missed it.
This instruction will apply to both rooted and un-rooted devices, but you will need to traditionally root your device or use firmware installer software, to make it through if you belong to those with un-rooted tablets.
Remember, this is a delicate process for someone who is performing it for the first time. Make sure you backup all your data, and keep a copy of the original firmware just in case you don’t like the new one, but it will rarely get to that extreme, if you follow the above instructions.
