Salve a tutti , da una settimana ho avuto questo problema : Lo smartphone non aveva quasi più batteria ( 12% ) e tutto d'un tratto si è spento , provando a riaccenderlo vibra , mi arriva alla schermata : SONY e si riavvia , anche dopo avere caricato la batteria al massimo , il cellulare in questione è un Sony Ericsson Xperia Pro MK16i , Provando a collegarlo al pc non mi riconosce il cellulare con il programma Sony Companion , esiste una modalità di recupero? Se sì quale e come accedere? Grazie in anticipo!

Ciao, il tuo telefono è in bootloop e molto probabilmente è possibile recuperarlo. Intanto hai provato ad aggiornarlo manualmente con il tool di sony?
Update service - Sony Smartphones (UK)
Dal tuo posto mi sembra di si ma non conosco il nome dell'updater di sony quindi te lo scrivo comunque. Il software che hai attualmente installato è originale senza modifiche giusto? Comunque ti suggerisco questo forum:
{PRO} Complete List of Roms | Kernels | Rooting/Other for Xperia Pro (MK16a/i) iyokan - xda-developers
Qui trovi tutte molte guide per provare a risolvere il tuo problema, a mio parere se l'update ufficiale non funziona, l'unico modo è avviare in fastboot e flashare da zero il sistema operativo originale (o modificato se vuoi) tramite android sdk .
Ho trovato questa guida ma ne troverai altre cercando su google "bootloop nome tuo telefono" (fonte: https://forum.lowyat.net/topic/2185722):
Cosa dovrai fare a grandi linee:
scaricare l'sdk di android
essere sicuro di avere i driver del tuo terminale installati
riavviare il tuo terminale in modalità fastboot e collegarlo al pc
aprire il prompt di dos (clicca su start e nella casella cerca digita cmd invio)
da li cercare la cartella dell'sdk che hai installato e cercare in particolare la cartella contenente il comando fastboot.exe
copiare in questa cartella i file originali (o anche non originali se preferisci) da flashare
usare il comando fastboot per riportare il tuo telefono a funzionare
Questo è l'ordine da seguire, leggendo la guida qui sotto prova e poi nel caso riposta. Ovviamente prima di fare qualcunque cosa leggi bene la guida e tutti i link.
ROOT GUIDE FOR XPERIA PRO (MK16i)
- compiled by siuyi - tested and certified usable on a THORUS set.
1) Download this zip (xperia-pro-root-recovery.zip - 11MB):
xperia-pro-root-recovery
2) Extract the zip to desktop and name it 'xroot'.
3) Open the folder and copy the file 'RootXperia.zip' to your phone's SD card, create a folder named 'downloads' and paste it there.
4) Download this Stock-based kernel (boot.zip)(Rooted with CWM Recovery + Handy Shortcut during Startup):
http://forum.xda-developers.com/attachment...85&d=1321907423
source: CLOSED - xda-developers
5) Extract the boot.zip, and copy boot.img into the 'xroot' folder on desktop.
------------------------------------
++ To unlock bootloader, refer the link below:
Unlocking the boot loader | Sony Xperia
i) read the important information by SE and click 'start unlocking the bootloader' button at below.
ii) stop at step 7 by copying down the code and direct jump to step 11 (unlock button for MK16i is MENU button).
iii) for step 13, If Windows asks you to install the drivers, install the driver from the folder “Fastboot Driver” in the folder you downloaded in (1).
iv) for step 14, open command prompt and change the directory by keying in 'cd C:\Documents and Settings\[your pc name]\Desktop\xroot' . After that, refer step 15 and 16.
Done. bootloader unlocked.
------------------------------------
WARNING!! YOUR XPERIA PRO WILL BE FLASHED THOROUGHLY LIKE A NEW UNIT ONCE ROOTED. BACKUP ALL INFO FROM YOUR UNIT INTO YOUR SDCARD OR PC TO AVOID UNWANTED CASES!!
------------------------------------
4) Put the phone into fastboot mode:
i) Power off the phone and make sure it’s not plugged into anything.
ii) Hold down the MENU button and connect the USB cable. A blue light will appear at the notification led.
**If a blue light does NOT appear, then your phone can't get into FastBoot, and probably still has the bootloader locked. You can also try a different USB port on the computer, and even a different USB cable.
5) Double click the dos batch file 'Root-Xperia-PRO.bat' in the 'xroot' folder on your desktop.
6) A dos window will open temporarily for a few seconds, and close. you might not even see it it's so fast. Wait for around 3-5 seconds.
7) Look at your phone's screen. You should have an orange colored recovery menu, which is the CWM-based Recovery v4.0.1.4 application running.
**Slide open the keyboard: The up and down buttons move the selection up and down. the Enter button selects something. the BACK button goes back.
8) Select 'install zip from sdcard' > 'choose a zip drom sdcard' > 'downloads' > 'RootXperia.zip' > 'Yes - Install RootXperia.zip'
9) Wait the flashing to complete, go back to the main screen, select 'wipe data/factory reset' and 'wipe cache partition', in 'advanced', select 'wipe Dalvik Cache' and 'wipe battery stats' , and return to main menu, select 'reboot system now'.
Done, your Xperia Pro had been rooted. Mind that the restart will take longer than normal.
10) Enter to fastboot mode again, refer (4). Then reopen command prompt setting like what you did in 'unlock bootloader (iv).
11) Type in 'fastboot flash boot boot.img' after the command. Your unit will come to an orange background which is the CWM-based recovery mode. Reboot the system.
Your unit is now with recovery shortcut during startup, by pressing the 'Volume Down' button once when the static Sony Ericsson white wordings become brighter.
Add-ons (siuyi haven't tried anything from this point onwards)
1- Upon unlocking bootloader and rooting your MK16i, if you tend to update your unit via pc companion under 'Support Zone' (also known as FOTA Update, Firmware over the air update), our update will be denied OR you WILL brick your phone. If you happen to brick your phone, do not worry and refer below.
REPAIR it due to FOTA Brick or ENABLE FOTA update, read the link below:
Enable FOTA update for UNLOCKED bootloaders WITHOUT brick (recommended)
[FIX] Enable FOTA update for UNLOCKED bootloaders WITHOUT brick - xda-developers
and if the above doesn't work, try the method below:

2- To relock your phone's bootloader, read the link below:

****Credits goes to rcummings100 and Bin4ry from XDA Developers Forum, FreeXperia for the CWM recovery image, and jeopardise from Lowyat.net for the heartful guidance.****
disclaimer : siuyi holds no responsible on your unit. Be a man, do the right thing. If you bricked your phone, refer 'Add-on (1)' to solve the problem. Unlocking bootloader voids warranty? Then refer 'Add-on (2) to revert back before you send off for warranty claims. There might be wrong info in the guide above as well.
---------------------------------
If you do not plan to unlock your bootloader, you can try to root your unit using the below method:
[Daily Update]Root / Unroot Sony Ericsson Xperia 2011 v1.5 without unlock bootloader
*Note that some upgrades which requires rootings requires bootloaders to be unlocked as well. So it is your choice to choose between unlock or not for the bootloader.
For recovery applications, you may install boot.img via step 10 (if im not wrong).
