Seems like software failure. Try flashing a ftf using flashtool

[Q] Xperia Mini St15i continuosly rebooting.

When I turn on my Xperia Mini, I first see the sony logo and then I see the xperia logo and then the screen turns off. The phone automatically starts again with the sony logo, xperia logo and so on.
I have tried starting the phone in safe mode by holding down the volume key or by repeatedly pressing the menu button but both of them do not work. I have also tried to "repair" the phone via the PC Companion but it detects the phone only momentarily(as it switches on).
This problem started soon after I had switched on the bluetooth radio on my phone.
My phone is running on Android 4.0.4
This problem did occur in the past but I was able to open the safe mode then and a factory reset solved the problem at that time.No such luck now.
How can I hard reset the phone without reaching the menu??
Or is there any other way to solve this problem??
Please help.

Have you tried to install a custom rom or have you got any idea why this is happening?
Do you know how to flash with flashtool? If not look in my signature there is a rooting guide. In the rooting guide on how to root gingerbread 4.0.2.A.0.62/69 you can see how to flash with flashtool and after that, if you want, root it.
If your phone wasn't rooted and your bootloader is locked and you haven't installed any app which could cause this problem, bring phone to service, but only if this could be hardware related and you haven't modified anything
Oh my science! You've been here since 2009 and this is your first post!?!?
Don't worry Your kernel is clean the problem is with the Rom.
Just flash the stock firmware ftf for your phone using flashtool and it'll be brand new again!
This will be useful
http://forum.xda-developers.com/showthread.php?t=1568792
There are numerous tutorials about flashing ftf through flashtool just google it (the above link will be also useful).
Flashtool can be used with locked bootloader . You can use it on a out of box phone right away.
hit thanks if I've helped!

I have experienced the same problem with my Xperia mini pro (SK17i). Just try to switch off Bluetooth before it restart. May be it will work on your device too.
Is it possible that bluetooth problem is an issue on android 4.0 ICS?

I too faced the same problem in my ST15i....Bluetooth works fine for a few times and after that suddenly it creates bootloop. When for the first time i went to the service center he told me that the ICS release is having a bug and it is not completely compatible.
I have also tried many custom roms with my bootloader locked. But the problem is same.
I feel that the problem is with the stock kernel and stock ICS rom compatibility.
Devs, please look into this and please develop a perfect solution. :good::fingers-crossed:
phone not starting up
i also have this rebooting problem b4 that time i just unlocked my bootloader by test point method the mobile functioned properly
but again the same problem exists this time i tried relocking bootloader by test point method and tried to flash it.Also i tried using s1 tools also after that my mobile is not even switching on 1 vibration is coming and no other further action
I heard that this is the best forum for flashing and rooting android

I also had Xperia Mini which gave me blue tooth problem.
1) Take out ur phone battery & connect ur phone with charger & switch the phone on.
2) Leave ur phone for about 10 mins and then while restarting put ur battery in the phone.
3)Take out the charger while restarting & ur startup will be more longer.
4) Then quickly go to setting &switch off the blue tooth.
5) Ur phone will restart again but this time ur phone will be working.
NOTE
In this process take out ur Sim Card & SD Card fron ur phone.

[Q] No flash mode O.o

Hi guys!
I can not run flash mode in a neo (note here, this is not my phone, I only trying to repair it somehow).
When I turn it on, only sony logo appears, than xperia logo aaaand it reboots. When I'm trying to start flashmode, (holding "back" than connecting to pc) it is just turning on, sony logo, charging (also when I'm trying to start fastboot mode). What can I do with it?
(plus info: the owner of this phone was try to upgrade his rom to android 4.1.2, and I don't know... maybe he did not unlock the bootloader or didn't flash the kernel or what...)
Try restoring the phone with sony companion

To enter flash mode, you need to hold the "Menu" key and not the "back" key while attaching it to the PC. Make sure you do this when the device is turned OFF!

[Q] Sony Z2 stuck with Sony Logo

I have a Sony Z2 with a locked Bootloeder with root, i tried to install the Rom in this Thread
http://forum.xda-developers.com/xperia-z2/development/rom-pre-rooted-deodexed-zipalinged-t2929194
Everything was working so well, finished installing the rom and then i tried to restart my z2 but i see only the Sony logo, can not switch it off anymore or boot into Recovery mode, the battery is very low, not able to do anything as my Device restart all the time.
Can someone help me or i have to send it to Sony ?
Have you tried flashing a stock rom with flashtool? Assuming you can still access fastboot (hold volume down whole plugging in USB on a computer, it might be volume up if that doesn't work, it slips my mind as to which it is)
Sent from my Xperia Z2 using Tapatalk
I was in the same position. I use flashtool, create anew bundle, flash a new tft and all's good - fone is like new (*^_^*).
You've got your answers already.
And for the future, if you want to turn off the phone while it's in bootloop then hold power button + volume up at the same time and wait few seconds like that.

Can't access boot loader in Xperia z2

After installing an application, my phones screen turned off and now I can't access any part of my phone. I tried to go to boot loader but bootloader is locked so I can't. usb-debugging is off too. is there any particular way for me to get my Xperia z2 back?
please consider that because screen is off, I can't do things like turning usb-debugging on in setting.
thanks in advance for any help.

Try to hold power and volume up buttons for a 10 seconds until phone vibrate(maybe need more than 10 seconds,try about 15 sec to keep them).If your phone vibrate just realse buttons and power him on.

I think you don't need usb debugging to re-flash your software via flashtool.

how do i check the firmware of my unit?
Download for E2303 if this is your phone's modification, then flash with Flashtool. Do wipe of everything before that and beware that all data will be deleted, so hopefully you have backup already.

thanks my friend, i already downloaded E2303, but when i do bundle the firmware, it is not responding , im am using the latest version of Sony Mobile Flasher By Androxyde
one more question,
do the CDA# , Market and Operator of the firmware does not matter??
You can use for different market if your phone is not locked to particular mobile operator. Try to reset phone first on this order:
1. Power off phone
2. Press and hold volume down button
3. Press and hold volume up button
4. Press and hold power button
5. Hold all 3 buttons for at least 30 seconds
6. Then try to flash your phone again
