(ROOT) (BACKUP) (TWRP) (DIAG) Sharp Aquos Phone Xx 302SH HOW TO ROOT, RECOVERY AND BACKUP // ROOT TUTORIAL BELOW!

Hi my XDA Friends!, I just got a Sharp Aquos Xx 302SH also known as Sharp W-072.a week ago and I love it! However, since this phone is from Japan (Softbank) I'm having trouble trying to activate the 3G/4G DATA CONNECTION on it. This is solved using an APN with password and username

In Colombia the network frequencies are the same as AT&T 3G/4G Network in the US, then I started my research to enable all the bands in it as it have a Qualcomm Snapdragon 800.

I learn some chinese and surfed in some chinese forums and posts, and I was able to recover the information about how to root this device, install TWRP and I also have a partition backup (for developing and recover from bricks)

This phone is amazing,

Dimensions: 70 x 132 x 9.9 mm, Weight: 147 g

SoC: Qualcomm Snapdragon 800 MSM8974AA

CPU: Krait 400, 2200 MHz

Display: 5.2 in, S-CG-Silicon LCD, 1080 x 1920 pixels, 24 bit

and a lot of things more! Check the Wiki page! In Japanese

If you need to put your device into DIAG mode you can download this and then push it into your phone, type this in adb:

adb push C:\adb\qxdm /data/local/tmp

adb shell chmod 755 /data/local/tmp/qxdm

adb shell /data/local/tmp/qxdm

Then plug your phone to your PC, it will be recognized as a DIAG device and will allow you to modify the frequencies for your baseband.

****This will turn on the DIAG mode in your phone for QPST editing, Please do this on your own risk.****
