[MT11 / Neo V] Enabling bluetooth caused bootloop brick. Can't access recovery.

[Evangeder]

I know how to fix the bootloop, but that will destroy all my internal data. And i don't want that.

The internal and SD drives are invisible to my PC. Windows do see the drives and installs drivers for them, but that's all.

They do not show up at My Computer screen, but the E:\ drive shows up at Device Manager.

USB drive is recognized as: SEMC Mass Storage USB Device.

When i want to access it using windows command line, it shows me that: " Device is not ready".

PC Companion does recognize the phone as MT11, and it shows the popup "yeah, there's an android device plugged in there", but the main screen still shows up: "There aren't any tablet/phone plugged into PC".

How do i access internal memory? I need to backup the application data (mostly the google authenticator), and everything else can be trashed. I also heard that deleting application cache and bluetooth folder helps to get out of the bootloop... but as i said, i cannot access the internal (nor external) memory.

The phone itself is rebooting as soon as it gets to XPERIA logo.

Sony -> XPERIA -> Blackscreen -> Sony -> XPERIA -> Blackscreen... repeat.

Holding volume down makes the vibration but the phone restarts anyways. So that won't help with anything. PC Companion wants to format my internal phone drive so big NO NO for that.

Any help?

There you go

I have found on the internet that this is a common problem with XPERIA's from 2011 year.

They sometimes randomly get stuck at bootloop after turning on the bluetooth option.

Some phones do manage to load to the lock screen, and then reboot. So it's possible to turn of bluetooth if you're lucky enough and it will stop rebooting.

My phone doesn't even want to go past XPERIA logo. I have no idea why is this a thing, but i lost my data 2nd time right now, and i'm probably never going to buy another XPERIA series phone. It could be everything. Everytime i enabled bluetooth it worked. Besides few months ago which this thing had happened. I used PC Companion to wipe my phone. Now this problem came back to me after the same action - turning on the bluetooth switch.

I managed to get QHSUSB_DLOAD device to appear in my computer, but there are no drivers for it, and i don't know what to do beyond this point. I'm polish, not spanish :x

I guess i gotta move to ye olde bricky 3310, at least there are no problems with phones from ~1999 year.

Edit: oh, okay, thanks! will definitely check that out

"Urządzenie dołączone do komputera nie działa." means "Device connected to the computer does not work"

Meh, i give up. I'll just throw this phone to a trashcan.
