desire z stuck on android skaters screen

Hello Everyone, I am a totally newbie.
I had a opening problem of Desire z with my first time root tried.
I followed every instructions, first of all it seems that everything was ok,
after adb settings, it was stuck on HTC logo screen. so I started with Hboot menu and I had to choose factory settings, secondly I cleared wipe datas, after it my phone was rebooted,
Now my phone was stuck on 03 green android robot which are skating on white screen. There is no text at the top or bottom.
For now i can not use hboot menu even I tried volume down + power button.
There are some options;
When ever I tried to press and hold volume up + volume down + power = it
has vibrated 4-5 times and green red light blinks.
Screen is black and nothing happen
When ever I tried to press and hold volume down + power = red led ligt blinks
I also tried to plug it on my computer via USB, nothing changes. Only my computer recognise a usb entrance but can not find any driver ( it is the same sound when you plug a usb into your computer)
I hope that I can explain my problems....
Waiting for your help, thanks

no reply i'm losing my hope to get my phone back

can you show a link to which guide you followed and where things went wrong exactly, also if you remember any specifics about your phone before you started

[Q] Flash mod for Xperia

hi guys,
I'd like to install CWM to my Xperia M C1905... how to put the phone to "flash" mode, please?
I tried volume down, up + power button => nothing
I tried Reboot your Xperia device pressing and holding the power button, when the LED turns pink then press the Volume Up button now the LED will turn Cyan from http://tips4droid.com/cwm-recovery-xperia-m-xperia-m-dual => nothing
Thank you.

To boot into fastboot: power off your phone, hold the volume up key and connect the phone to your PC with the USB cable. When the LED turns blue, release the volume key. This is the one you need for CWM.
To boot into flashboot (for flashing firmwares using Flashtool) you hold the volume down key instead.
To boot into recovery: press the volume up key while the LED is pink as you wrote. It won't work until you install CWM.

you need to install the rom ... not only the kernel ... once the purple led comes press the volume up key , it'll take you to the recovery . Do a factory reset and then install the rom ..

Stuck at bootloader unlocked warning

I have TWRP and LineageOS with Magisk installed on my A50. Normally, when my phone boots, I get the following sequence:
1. Phone vibrates.
2. Samsung Logo appears for a very short time, with bootloader unlocked warning at the bottom.
3. A screen showing a bootloader unlock warning at the top and "PRESS POWER KEY TO CONTINUE" appears.
4. After a while or if you press the power key, an additional unofficial software warning appears in red letters at the bottom.
5. After some time the phone continues to boot normally.
My problem is that after the latest reboot ("reboot into recovery" via power menu), it gets stuck at step 4 and won't continue to boot, neither recovery nor system, even if I wait for tens of minutes.
What I've tried:
-reboot with volume +/-/poweroff
-reboot with volume volume -/poweroff
-all of the following with and without USB connected to PC:
-power/volume +/- at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-power/volume + at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-power/volume - at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-volume + at boot, both starting after logo screen as well as starting before logo screen
-volume - at boot, both starting after logo screen as well as starting before logo screen
-volume +/- at boot, both starting after logo screen as well as starting before logo screen
None of these helped. I just get the normal sequence 1-4 and then stuck every damn time. Can't get into recovery or download mode. Can't even power off, obviously.
Is my phone gone for good?

With some help I managed to get into download mode, and from there reflash stock rom with ODIN.
Basically, you need to reboot the phone with power/vol+/vol- and as soon as the screen goes black, you release power but keep pressing the volume buttons, and also immediately connect the USB cable with the PC. Timing is key.

bro, you helped me alot, i'm stucked at this screen maybe 2 hours I didnt know what to do.
Btw, I've it just in 1 time =))

I got a way easier Method which has saved me several times
Is something i came up myself
Il be as precise as i can be so everyone understands!
1.Plug the phone to the wall (Your charger to the outlet)
2. Hold Power And Volume - (Volume down) until the phone shows the second charging animation (Which is the one after the first image of the phone charging [A circle with the lightning icon in the middle], this second screen shows a charging animation and the percentage of the battery) This indicates that the phone is fully Turned Off
3. Unplug your phone and the charger off the wall and bring it to your computer
4. Plug your cable to your Computer then back on your phone Hold Volume + and Volume - (Volume up and Volume Down) and plug your phone to your computer WHILE HOLDING BOTH VOLUME BUTTONS.
This little trick will put your phone in download mode so you can restore your device using Odin OR Flash Twrp with Odin and boot to right into Twrp (There is a way to do it without turning the phone on and having to go back to step 1, Follow this Tutorial to do it
(
)
I Hope this helps you all
And Happy Flashing!
