HTC One X (GSM - Tegra 3) : flashing [MOD] Lower Autobrightness values - battery saver - detailed

How I flashed the [MOD] Lower Autobrighntess values - battery saver (from j4n87) step by step.

I did it on an international HTC One X model (GSM and Tegra 3). I don't know if it works on other HTC One X versions, non GSM or non Tegra 3. So do it at your own risks.

1) Download the file from the link provided at the end of the #1 post [MOD] Lower Autobrighntess values - battery saver

2) It is wise to make a backup of your ROM. Detailed instructions can be found in HTC One X (GSM) : detailed instructions to unlock bootloader, install custom recovery and root at steps B.10) to B.14) of the B - Install a custom recovery section.
It also means that before any attempt to flash any MOD, you should install a custom recovery and make a backup of your stock ROM.


The step by step instructions are pretty much the same as the ones for installing SuperSU (root) in the C - Root the HTC One X section of HTC One X (GSM) : detailed instructions to unlock bootloader, install custom recovery and root.

3) Plug your HTC One X on USB

4) Put the Dim_autobrighntess_final.zip file at the root of your HTC One X sdcard (into the folder /sdcard). There are different ways to do it. I rather like to use the adb push command


droid $ adb push Dim_autobrighntess_final.zip /mnt/sdcard/
758 KB/s (10515491 bytes in 13.537s)
droid $ adb shell
shell@android:/ $ cd /mnt/sdcard
shell@android:/mnt/sdcard $ ls -l Dim*
----rwxr-x system sdcard_rw 10515491 2012-05-12 06:39 Dim_autobrighntess_final.zip
shell@android:/mnt/sdcard $ exit
droid $


5) Wait 5 seconds then unplug the USB cable from the HTC One X

6) Power off the HTC One X

7) Power on the HTC One X in bootloader mode by holding Volume-Down button while pressing the Power button.
FASTBOOT should be highlighted in blue.
Before doing this, you should ensure your phone has at least 50% battery !!

8) Select RECOVERY using the Volume-Down button, then press the Power button.
The "quietly brilliant" white HTC screen appears briefly.
Then the "ClockworkMod Recovery v5.8.3.1" black screen appears.
The "Reboot system now" item is highlighted in blue.

9) Touch the 2nd item "install zip from sdcard"
The screen "Apply update from .zip on SD card" appears with the item "choose zip from sdcard" highlighted in blue.

10) Touch the highlighted item "choose zip from sdcard"
The screen "Choose a zip to apply" appears with a list of files and directories.

11) Scroll through the files and directories (with your finger) until you see the file Dim_autobrighntess_final.zip (at the end of the list). Then touch it.
A new list appears

12) A new list appears with a lot of "No" and the item "Yes - Install Dim_autobrighntess_final.zip" in the middle. Touch the "Yes - Install Dim_autobrighntess_final.zip" item.
The installation begins and a log is displayed at the bottom the screen.
When the installation ends, you're back on the screen "Apply update from .zip on SD card".

13) Touch the last item "++++Go Back++++"
You're now back on the screen "ClockworkMod Recovery v5.8.3.1"
The "Reboot system now" item is highlighted in blue.

14) Touch the "Reboot system now" item.
The HTC One X reboots.
A dialog box "Android is upgrading ..." appears with the message "Optimizing application nn of nn"

The new auto-brightness settings are now active.
Enjoy ;-)
