GT-S5660 stuck in "Downloading..." screen - Samsung Galaxy Gio GT-S5660

Hi all,
My phone got stuck on the main Samsung screen so I tried flashing new ROMs with Odin and it always got stuck on the "setup connection" phase. I tried few times and now I can't even get to the download mode, only yellow text "Downloading..." or black screen.
Is there anything I can do to unblock it? I tried removing the battery, waiting, putting battery back, waiting... but nothing. I managed to get out of downloading once but now it's back and I find it even difficult to pass the completely black screen.
Thank you.

[Q] I've made a huge mistake, flashed Verizon S3 kernel on ATT, phone will not boot

I tried flashing the Zeus kernel using CWM, but I failed to realize the kernel was for the Verizon S3. When I restarted after flashing, it displayed the Samsung logo for a split second and then went to a black screen. The screen was on, but it only showed black. At this point I passed out, and when I woke up it was still on the black screen. I pulled the battery and tried to restart, and got the same black screen. Then I tried every way I know of (except using a jig) to get into download mode to no avail. Now when I turn it on, it vibrates once, flashes the logo, and then the screen shuts off and is useless. I think there's a solid chance I've ruined it this time, but if anybody has any suggestions they would be greatly appreciated. Thanks!
Put the phone in dl mode. It's possible the screen will be black and you can't actually see it's in dl mode. Plug into your computer. Odin flash a stock Rom.
The fact that it's doing something means it is not completely ruined. It just may be harder to restore to working order.

Phone Stuck, Stutters then Fails.

Hi. So my htc m8 just turned itself off and when I turned back on it was stuck on the htc logo. I tried all sorts to fix it. I press Volume up and power to re-start then quickly volume down to get into download mode or what ever it is. I then went to factory reset where it went to a black screen with a green circle around a green arrow. Then it just goes back to the htc screen and gets stuck. Ive done this a few times and sometimes I get the pone to the main set up with country, wifi terms of use and that. When I get passed that I get this message: Sense Home has stopped unexpectedly. Would you like to send error report to htc? That pop will just take over, cant get passed it. I can go into setting an and have tried factory reset from there but same thing just starts over. Please can you help? Phone isn't rooted or had any custom roms put on. Running 6.0 Marshmellow.
Thanks :angel:

interesting Oneplus 3 issue

So, the phone works, but when it turns on, nothing displays at first, no logo or loading animation. but, once its fully tuned on, everything shows again. now, the real issue... I cant get into recovery mode, or anything to try and get it factory rest or flash new firmware on it to fix the issue, because the screen displays nothing when I'm trying to access recover menus. it just stays black until i disconnect the batter and let it turn back on normally all the way.... tried some research and did the usual black out issues... but nothing.
any help would be great thnx!

Phone stuck on black screen even soft reset does not work

Hi,
I tried bunch of stupid **** today on my phone to try to update it and now its stuck on black screen. I tried to open recovery mode too but nothing shows up. Just a while ago it was boot looping with android logo and "Your device is unlocked message" but even that stopped now. Is there anything I could do or is this thing dead for good?
P.S. the device does not show up on ./adb devices as well
