[q] help i destroyed my phone

Hello
Yesterday i tried to overclock my sgh-t999 with "ALL STARS KERNEL DEVELOPERS" but something wrong has happening and now i cant open my phone.IM stuck i cant entry on download mode or recovery mode to make a reset.NOTHING WORK what to do to reset my phone cuz i dont know what to do in this momment.IM STUCK.
Are you sure that you are unable to get into Download mode? Try this pull the battery, then replace it and then hold Vol Down & Home then pressing Power until it vibrates, still holding Vol Down & Home buttons, until the "Yellow Triangle" screen shows up. and Recovery is the similar with Vol Up instead.

[Q] F240L Stuck at bootscreen

my phone is stuck on bootscreen I tried flashing it following this method. Everything went successful but I can't go to recovery menu to reset the device cuz it's stuck on bootscreen. Anyone got any idea how to fix this?
I have found, on my phone anyway, that when you hold the volume down key and the power key it just sits there. I have to hold the buttons, let the power button go til I see the "LG" logo and hold the power button again. Then it gives me the factory reset screen. But you have to let go of the buttons as soon as you see this menu. Then you can hit power, hit power again, and it boots into recovery. Give that a try and see if it works.

ok so I hold down both power and volume down button then the lg logo showed up I released the power button and hold it again then the lg logo disappear and comes again and then it goes blank (um still holding both of the buttons) and the notification light keep on blinking. um really starting to get worried here I exchanged the phone with my galaxy s3 there is no way I cud return it now and I wudn't even try to re-flash it if it wasn't for the miui rom it had installed when I got it. I just want my phone to be at default 4.1.2 and now I'm clueless :crying:
however if I press and hold power and volume up button and when lg logo appear I keep pressing the volume up button rapidly this shows up:

i dont even know what it says its like in korean or something
That looks like the Korean download mode. When I use that method to get into recovery it's a bit tricky. I hold both buttons, nothing happens, while stil holding the volume down button, I let go of the power button just till I see the LG logo, then I hold the power button again til the small menu pops up. You have to let go of the buttons really quick when you see this menu because the power button and volume buttons are also the select button for this menu. Holding the buttons too long causes the menu to think you want to exit it....At least that's how it acts on my phone.
Remove battery, wait for 5 sec, attach battery again. press and hold power + volume down + home key, when you see reset option or recovery press power button to confirm and it will be fine.
Just try in the lg mobile support tool on top left and select update recovery the firmware will download and the phone will alobe get in the download mode and you don't have to do anything.

THIS TRIC'LL DO IT, BUDDY..... SUGGEST NEXT TIME YOUSTAY CLEAR OF THE HIDDEN MENU THOUGH!!! UNFORTUNATELY YOU'LL LOSE ALL OF YOUR DATA..NO JUMPING THIS.
1. Start your phone up by holding onto both the power button and the buttom volume key. When the logo pops up, let go for a second, and hold onto both buttons again. This should bring up the option to reset your phone. Agree to both prompts.
2. You should be on a new screen. It may warn you not to touch the screen because it is calibrating or testing it. You will have to press OK, and then give it a few seconds to do that bit.
3. The screen should have a list of options at this point (some of which say "+power) on them. If you want to use any of these options, you need to hold the power button, and then press that option on the screen. Press "normal boot (+power)" (don't forget to hold the power button at the same time). This should put your phone back to normal, and set it up again just like it came out of the box.
ENJOY YOUR PHONE BACK

Power button not working in Hboot. Stuck in safe mode!

Hello, I have searched the forum but cant seem to find an answer or a problem similar to mine.
So I was using my phone as normal and the power button wouldn't lock the screen. I held in the power button and it brings up a message saying hold power and vol up for 10 seconds to restart so the power button was obviously recognised.
I reboot into the hboot menu and can move up and down but not select, again the power button at fault. However when I hold the power button in here it turns the phone off.
When holding power button and vol up in hboot it reboots to safe mode, with the power key working exactly as it should locking screen and holding in for power options. There have been no recent app installs to cause this.
If anyone knows/ has an idea why it would be greatly appreciated .

Google Pixel stuck in Fastboot

Hi,
I've got my Pixel on February 2017 from Virgin Megastore in Dubai, all things were going right until last summer after a beach day, I realised that my volume down button does not work anymore and sometimes it still pressed (the button is not pressed physically) which puts my phone on vibrating mode maybe due to humidity or some dirt
I tried many solutions found on the internet: sucking the button, cleaning with Isopropyl alcohol… but no success
This weekend I noticed that my phone consume battery more than normal, tried to restart it but instead of rebooting normally the Fastboot appears
Now I’m stuck in this mode because my volume button down does not work and the power button work like if it is the volume button down, so I can switch between modes (start, power off, barcodes, recovery mode, restart bootloader) but I cannot select none of them
I tried to hold down the power button but it reboots on the same screen
I really don’t know what I can do
Please help me if you have any idea
Thanks in advance
Su fastboot reboot bootloader
Then flash the stock.
It needs USB Debugging to be enabled ? I'm not sure I had enabled it before that when I android starts normally.
Please share with me if you have a tutorial of flashing ROM that would work in my case
Thanks
Just wanted to tell you that I fixed the problem with a “hair dryer”, the volume button down starts working and I could restart the phone normally.
Thank you for you help
