Stuck on LG boot screen(no boot loop just frozen) - LG Optimus L9 P760, P765, P768, P769

I urgently need help as my lg optimus l9 p769 will not boot past lg screen (it is not a boot loop it just stays frozen for about 4 seconds then it shuts off, then if I put my charger in, it boots to the lg logo and permanently freezes there)
this first started when I changed my cm 10.1 theme, I left my phone but when I came back it was off. the only way for me to turn it off was to take the battery out. When I took the battery out and put it back in, it would automatically boot itself up. Eventually I decided I better change my recovery from the physical keys to the touch screen one. I flashed a touch screen clockwork recovery through adb from my command prompt after I did that I decided to boot into the recovery so in the command prompt I typed up the command to boot into the recovery when I did that nothing happened and I was still in fastboot mode. So I decided to shut the phone off, after that that's when it started to not boot past lg logo screen and freeze on logo screen after I put in the charger.
I cant get into download mode
my recovery does not work
my power button might be broken( I cant tell as it suddenly stopped working for no reason after I applied a new theme)
(I will open up my phone if I need too, if I do how would I disable the power button, or fix it)

[Q] Stuck on Boot Animation

My phone restarted one day and just wouldn't boot up. At first it was just stuck on the SAMSUNG logo, but after trying to boot into recovery, it now sits at the boot animation. When I try to boot into recovery, the CWM screen will come up, but no menu will show up, and then the phone will restart after a few minutes and go back to being stuck on the boot animation.
I can enter Download Mode, but USB Debugging must be disabled since ADB won't recognize the device and I can't send any commands (yes, drivers are installed).
First of all, is there any way I can recover the data on the phone? That is more important than getting the phone working, since I was just about ready to get a new phone anyway.
What can I do to get the phone working? Everything involving flashing a new kernel, or resetting the phone back to factory seem to require a working recovery or the ability to send commands through ADB, but I'm probably missing something, since there must something else that I can do.
Any help is greatly appreciated. Thanks.
**Not sure if this is related or not, but the reason why the phone restarted before this issue occurred is because the power button on the phone is a bit faulty. Over the past couple months I've been having issues with the power button; it seems overly sensitive so when I push it sometimes the screen will turn on and off and other times the phone will just restart as if I held the button down for too long. This is the main reason why I was ready to get a new phone.

[Q] Phone stuck in boot loop. I cannot access recovery mode or download mode

I have a samsunng galaxy note 2. I installed DN3 v3.0 2 days back. The phone was working fine. Today I installed an app from outside and was using it until my phone battery went low. SO I swapped the battery as I normally do. But this time phone wouldn't boot. It is stuck in a boot loop. As I put the battery, PHONE WOULD AUTOMATICALLY TURN ON!!!
And it will stick on the " samsung galaxy note2" screen. Then the screen would go black for a second or two and repeat. I pulled out the battery and put it back, again the same. I tried putting back the old battery, but in vain.
I cannot access recovery mode, and when I try to enter download mode, the phone would stick to that screen where it asks either to press volume up or volume down button to enter or exit download mode, and then again it would try to boot and stuck to boot screen.
Please help me, I don't know what to do.

Boot problem - I9300

Hi,
So my S3 stopped working a few weeks ago while I was on holiday. It fell from my hand and turned off on its own. After that I turned it back on and it was working fine for a couple of minutes, then the problem started happening.
Every time I opened an app that used the camera, the phone would reboot. After a couple of reboots, it would get stuck repeating the Samsung logo (haven't been able to boot it since then). When I plug the charger in, it passes the Samsung logo and then stays on the Cyanogen mod logo. I've left it on for hours on the CM logo without any luck. I can't boot into recovery mode because the vol. up button doesn't work, and I can't get adb to find the device on my pc (though it does charge when plugged into the pc).
All I'm wondering is if there's a way I can save my media files from the phone myself, or if I need to take it to a service centre.
Tl;dr - phone loops samsung logo when on battery, gets stuck on cm logo when charging, vol. up broken so can't get into recovery mode, adb won't find the device so no recovery mode like that either, want to save media files.
Any help is appreciated. Thanks

Well now let me tell you how this problem occurred, well my friend bought this phone from someone, so he doesn't know if there was custom recovery ever installed on this phone or if it's on stuck recovery
the phone was working fine, then one day an update notification pops up, he does the update, the first time it showed him an error message, but he tried one more time and it got throw the update process, unfortunately the phone got rebooted but never made it past the boot screen
now because the phone won't shut down, i can't get into fast boot or recovery mode (i don't know how to do that unless the phone is shut down, and doing the volume/power button combination)
i'm really stuck here and don't know what to do, i'd really appreciate your help guy
PS: sorry for the English, that was the best i could do
EDIT : i managed to get into fastboot mode,yeeeey! (see the 4th attachement)
how did you get into fastboot mode
i am not able to do it

Oneplus X not booting or charging

So I have a OnePlus X with AOSP 9.0 installed. I tried to root it using SuperSu and when I tried to reboot it after the process was done, my phone got stuck in a boot loop. The OP logo would come on the screen for a second, the phone would vibrate and then automatically go away repeatedly. I was unable to access the recovery and was only able to get the phone into fastboot mode which told me that phone has a locked bootloader.
I feel like I might have accidently corrupted the partition that has the phone's BIOS or something
Eventually my phone ran out of battery and now I can't even charge it to be able to get into fasboot mode again. I have tried leaving the phone plugged in for two days but it isn't charging. It keeps going through this cycle of charging for a second and then not charging and wasting power for 3 seconds and leads to no gain in charge.
I also have a video of the charging boot loop if someone needs to see it.
PLEASE HELP ME :crying::crying::crying:
