[Sony Xperia T, TL, TX, V] Amplifiction:
Hi guys,

My phone is in a permanent state of rebooting. I have searched these forums and other websites, but none of the solutions I found apply to my situation. I am going to provide as many details as I can here, even if they seem irrelevant.

My phone when it crashed

Sony Xperia V, stock firmware 9.2.a.1.210. (Which is the second latest. Couldn't get latest because neither Sony PC Companion or Update App found updates. This was BEFORE rooting.)

Rooted this morning using Towelroot.

(EDIT) Then I installed latest version of SuperSU.

Unless Towelroot somehow unlocks bootloader, I have a locked bootloader.

Deleted some pre-installed apps (which is why I rooted in the first place). Using Clean Master, I removed:

Google Play Movies

Google Play Books

Google Play Magazines

Sony Select

Sony Music Unlimited

Sony Xperia Link (Not sure about name. Used to view stuff like messages on other devices. Purple icon.)

I think that is all. I'm pretty sure I didn't remove anything vital. (My knowledge of Android is limited, and so I didn't go on a killing spree.)

Using Xperia Smart Connect, (I decided to try it after all), I set up an event. (When connecting to my TomTom Go, switch off Wifi. Afterwards, Switch on Wifi. The TomTom was turned off.)

Everything was fine after that.

The crash

Later on, I wanted to take a picture using the stock app. The app launched and worked for a few seconds, displaying what the camera registered. Then, the screen froze. After some time, I tried turning off my phone, to no avail. So I removed the battery. Re-inserted battery, pressed power button. Since then, my phone keeps on rebooting.

What happens exactly

After I insert the battery and press the power button, the phone vibrates and seems to boot normally. I get the colorful boot animation, followed by the lock screen. A lot of systems seem to be functioning correctly:

The lock screen looks normal. It displays the background I have set (from the stock Winter theme, I think) and shows the authentication dialog (more on that later).

The displayed time was correct after the first few boots, before I removed the battery for longer than a few seconds. After that, it was wrong a couple of times, before getting it right again a few boots later.

Other icons being shown in the status bar: Bluetooth (grayed out, which is normal if there's no connected device), no SIM card, no network, battery status (correct) and Wifi (best reception with constant up and down arrows).

The notification LED works. (Changes with battery status.)

"Battery almost empty" sound when applicable.

My phone never registers any input on the touch screen, save for one time, when it registered the first digit of my PIN code. After a while of displaying the lock screen, the whole screen turns a certain color (I've seen different colors on different occasions: red, purple, ...) like some kind of color filter is being applied. (The image is visible, but in one color.) After, that it fades into black and reboots.

What I have tried

Charging the phone for about an hour. The power led is orange when charging, meaning the battery has a decent amount of juice.

Removed the battery several times (one time for over fifty minutes). After I re-insert it, I need to press power button to get it to boot, which is of course normal. (As opposed another thread I've read, where the phone would boot as soon as the battery was inserted.)

Connecting to PC using USB cable and Sony PC Companion (SPC). SPC can't connect, most likely because the phone reboots before it can finish detection process.

Tried a forced reboot by pressing and holding power+volume up. Has no effect.

After a few reboots, I removed SIM and SD cards. The only effect that had: instead of the enter PIN code dialog, I get the "connect the dots" dialog. (Which makes sense.) No input is being registered. The pattern (dots) used to be my secondary authentication method, the primary being facial recognition. My phone doesn't seem to initiate facial recognition.

Let it reboot repeatedly. I estimate it has rebooted 15-20 times now.

On flashing

If flashing is my only option, I want to try Cyanogenmod instead of Sony firmware. I'd rather not flash at all, though, since I have no experience. All of my data has been backed up, so an internal wipe is no deal breaker.

If I do have other options, I'd prefer the quickest and simplest method of getting my phone operational. Provided there is one...
