[Q] Piyush

How do I hard-reset my sony xperia mini st15i? There back and menu buttons are both touch buttons. I tried the power+back+menu button combo... no use.
Hey piyushw,
To hard-reset your phone, hold down the power and lock button keys for five seconds and the phone will automatically restart.
Greetings,
KanocX
Hey Thanks KanocX!
Actually my touch screen has stopped working so I was trying to hard reset it. There is a power button on the top, a home button and two volume buttons on the side.
Tried out various combos with them. Still not working.
Hey piyushw,
have you tried simply take out the accumulator?
Greetings,
KanocX
Hey KanocX,
That was the first thing I did. Removed and reinserted the battery couple of times.. everytime the screen goes un-responsive.
Thanks,
Piyush
Hey piyushw,
is this phone rooted?
Greetings,
KanocX
Hi,
No it is not rooted.
Thanks,
Piyush
Hey piyushw,
I think the best solution is, to send the phone back to Sony to repair it...
I don't think if that's possible in your country, but in germany there is a law called "warranty". Call Sony for further information.
sorry, that I couldn't help you

[Q]Car bluetooth not working properly

I have ProBAM on my Galaxy SL. It is a 4.2.2 ROM, so the problems related to car bluetooth in GB and ICS should have been solved. But when I connect it to my car (a Toyota Yaris, should this help) and someone calls me, I have like 50% chance to be able to answer. At times, it just keeps ringing and when I press the green or red button on the touch screen or on the wheel nothing happens. Any idea on how to solve this?

Same problem here. Also noticed that the device in store on display had the same thing on the screen. And it was almost fully charged (98%) and still didn't turn on. Anyoen found a fix for this?
EDIT:
After many many reboots and connecting NFC spots to another it finally made a connection and about 15minutes later watch was working.
Try this
Try this:
Press and hold power button for 5 seconds to shutdown then wait 3 seconds and press and hold power button again 5 seconds to power on and connection logo is appeared
just use a usb charger

Same problem on an usb hub. Just try a real usb charger. It solve the issu for me.
I hope its help.

Same problem here, put the thing to charge and when I switch it on it shows that .3 25 11 message and nothing else happens, just bought it on amazon and didn't work since the very first moment... So I can guess it's going back to the shop with a promise of not buying anything else from this brand. Shame on Sony

[Completed] Teclast X10 not turn on display

Hallo I have a Teclast X10 and I have a problem, strange problem. Since a time the power button does not work properly: it turns on the tablet, it turns off the display but it does not turn on the display again. It is not always like this, sometimes it works (less and less times) but when I am not able to turn on the display if y press the volume button I can hear the sound of the volume, but the only solution is to reste the tablet but the micro-button.
I think it is a software problem but this tablet is only used to youtube and videos.
Could anybody help me?
Hi there and welcome to assist,
Unfortunately there is nothing about your question on XDA forum. Try a Google search first.
Good luck

Bricked Witson PX3 MTCD >>Solved<<

Do you know how can I enter recovery / reinstall firmware on a Winston PX3 without any buttons? just reset.
The unit is made of Opel Insignia and uses the car button. The power power button only switches the screen on / off and nothing more.
Is stuck at the lollipop logo without anything else.
I tried all the method here... reset, keyboard without any luck
RK tools not working since is not seen by the laptop
Bootable SD, same... no luck.
Thanks in advance
I also want to know that, never find solutions at this time.
I have same car with same head unit, do you have a good radio reception?
Read here and tell us if it works ... on my witson px3 android 5.1.1 works this procedure to enter in recovery... good lock

Solved after taking out the unit.
The trick with power button does not work since on Insignia access to the power radio buttons is via canbus interface. Power button only switches screen on and off when not in Android... nothing more.
So solution:
Is easier if the unit is not mounted in the car, I have not tried to enter recovery after a reset, but maybe I will try sometime.
1. Disconnected all power from the unit... ACC & BAT disconnected
2. Prepared 12V power supply with on negative and two positive connectors
3. Connected negative to GND & one positive to BAT
4. Connected USB keyboard
5. Press right ALT (ALT GR on some keyboards) and PrintScreen
6. Connected the other positive lead to ACC (unit does not work if both BAT and ACC are not connected)
6a. Start pressing repeatedly on E (not holding E pressed, but press...release... press... release..... rapidly)
7. The boot logo shows (Lollipop...etc) and after a few seconds the unit reboots itself
8. Release right CTRL & PrintScreen and continue to repeatedly press on E.
9. The Recovery shows on screen.
Sweet success at last.
I put a USB stick with Hal9k room and selected install from USB and clean... waited for 15-20 minutes and everything fine.
Mounted the unit in the car after switching to MicroG and configuring apps.
Hope this helps others who have problems getting into recovery.

Hi,
Found solution, described in the previous post.
Reception is good. I had also a power amplifier mounted but did not improve reception futher so got rid of it.
Hal9k ROM with MicroG is much faster than stock one.
