Root [FiX] for all Xperia MiNi owners experiencing the OVERHEAT issue

root required
This script should fix the mini overheat problem.
Actually what it does is decrease the touch sensitivity of the two touch buttons.
It won't make your phone run cooler though :)
But the phone should be usable again. Meaning no random touch button activation, and exiting apps all the time, etc

Download Gscript or Script Manager from android market
https://play.google.com/store/apps/details?id=nl.rogro.GScriptLite&hl=en (GS)
https://play.google.com/store/apps/details?id=os.tools.scriptmanager (SM)

Input the following script as ROOT:

cyttsp_fwloader -dev $dev -fw /system/etc/firmware/$fw -verify_only
sleep 5
reboot -p

Or just download the script

You're phone will shutdown, so don't worry. Just turn it back on.

And that should be it. It should be fixed now! :-D

NOTE: ICS does not have this bug. There's no need to run this script when running ICS ROMs.

Hi i have executed the script and it went well i think, it shut down. But now the touchscreen is disabled :p i have flashed the software but it still the same, please help.

rooted st15

Weird... I've never heard of that happening.
Try to flash firmware with flashtool and see if it works.
Take a look at my guide under rooting section if you need help with that.
I've also provided links to firmware downloads.

After that try to flash you ROM of choice.

Also, I'm running CM7.2RC2, which doesn't have this problem. So you might wanna try that.

CM is short for cyanogenmod. A custom ROM.

If re flashing doesn't solve it, it might be hardware related. I've heard of cases like yours where the touchscreen wouldn't work.

You could try this firmware
download SE PC companion if you haven't got it installed already.

Find an option to repair/update device. I haven't used it in ages, so I can't remember the details....
If that doesn't work, than it's definitely hardware related, and you should take to service.

If you have an unlocked bootloader, download this Xperia_Relock_bootloader.ftf and flash it.
It will re-lock your bootloader. Because warranty is lost if it's unlocked.

CM is awesome fast and by my opinion better then stock :)
And so far I haven't had any overheating issues while running it.

BTW- FXP kernels are battery inefficient. So you might wanna use Rage kernel for CM.
My battery last a few days on it. And you have way more CPU governors to choose from. My recommendation is use smartassv2 or brazilianwax for best battery/performance.
