[ Q ] Xperia Pro Frozen USB / Black Screen

Hey guys i hope someone can help me out : )
Problem:
I froze some system apps on my xperia pro including mtp (the one that you need for the usb to connect to the computer)?!
well then i was using the phone like regularly and it suddenly froze.
Rebooted the phone ..black screen , the phone is booting normally but i cant see a thing of course.
Fastboot / Flash mode
With flashtool It says its connecting but then i get an error
With the cmd fastboot method its just stating "waiting for device" and when i connect it in fastboot mode nothing is happening just windows telling me thats something wrong with the usb connection and it wont work.
When the phone is turned on and connected to the computer i can see it listed in the device manager as mk16i
if that is relevant
Thanks for reading.
problem 1 : is your phone hardware qwerty button light up when you turn it on and dim when wait a few second? if similiar like that maybe you need to replace the flex cable
problem 2 : try reinstall your phone's driver and make sure you connect the phone in fastboot mode with blue notification led light up.

Desire HD bricked!

Hey guys,
I've flashed quite a few ROMs in the past 2 years. Today, I flashed a new ROM and it worked fine. After that, I installed Nova Launcher and changed the density to 160 and the phone asked for a reboot. However, it isn't booting after the reboot. I can see the white HTC screen for 1-2 seconds, after that the display dims and then turns off. Can't go into the bootloader or the recvovery. The phone charges normally (can see the orange light) and on connecting to the PC, it gives the successful connection sound. Any tips on how to fix this? I've done S-OFF long back if that helps. I've tried removing the battery and inserting after 5-10 mins, however I'm still getting the same output.
EDIT: Guys, just noticed that the phone isn't turning off after the HTC white boot screen. The backlight starts and then turns off after a second, and then starts again for a second and this keeps repeating..
Pull the battery.

Did you reboot holding power and volume-down?

Yeah, tried all possible combinations incl the usual power + vol down. The HTC logo appears for 5 seconds and then I can only see the backlight on the screen for another 2 seconds. This backlight then turns off and turns on repeatedly every 2 seconds and continues till I remove the battery again.
In short: No bootloader access, no recovery access. Just can see the device after I connect it to pc and type adb devices.
UPDATE: Fixed. Used the adb, on typing adb reboot-bootloader, I could access the bootloader. Thanks guys!
Same problem, Please Help!
My DHD, passes the HTC logo, then goes blank. The backlight doesnt go off, its just blank and remains like that indefinitely.
There is no charging led light when on the blank state,
The blank state does get detected by the computer.
Fastboot Commonader V1.51 says no fastboot device detected.
(P.S. My volume keys are water damaged and do not work, so i cannot use Vol- and power)

just try plug your phone to pc...then open cmd n change source to adb folder that you place..then type "adb devices" if your phone detected in there..then you can continue to next command type "adb reboot bootloader" or "adb reboot recovery"..next if you success go into recovery..just flash/ install another rom from there..
hopefully can help...
That worked. Thanks

Xperia Z5 Premium - Power button not working - can't get into fastboot mode?

Hello everyone,
I really hope somebody can help me with this.
I have xperia z5 premium, power button stopped working a month ago or something, but the phone was working perfectly fine. Of course, I made a mistake and did not charge it in time and it turned off. Now I can't get it to turn back on because the button is not working.
I explored all my options and I realized I can do fastboot reboot through fastboot and adb. However, I can't seem to get my phone to go into fastboot mode.
I hold volume up button (which I know for a fact is working), I plugin usb, and instead of getting that blue led light everybody keeps talking about, I just get a red led and then a green one after the sony logo that signals the phone is charging.
I installed ADB and xperia z5 premium drivers and I still can't get it to work. When I type fastboot reboot it says <waiting for device> when I try adb reboot or adb reboot bootloader it says "error: device not found".
I've also installed xperia companion app and when I plugin my phone it shows a screen where it says: "Your device is locked
1. Unlock require
Unlock the device using password or fingerpint if needed
2. Allow data access
On your device, select the option to allow data access"
I've tried doing the same thing with adb on two different pcs, always get the same result. Phone just gets to charging screen and keeps charging instead of going into any mode.
I also tried holding volume down button and plugging in usb which is supposed to be recovery mode or something, but that doesnt work either, I also get charging screen. And I'm 100% sure both my volume up and volume down buttons are working.
What am I doing wrong?
P.S - Debugging mode is not on, im 100% sure since i never turned it on.
Somebody please help!
Thanks!
