[Q] Help! Phone doesn't turn on anymore! - General Questions and Answers

Help!!
Today I tried to flash paranoid android to my rooted xperia z2, but now the phone won't turn on anymore!! If I hold the power button, the phone vibrates, but nothing happens. If I keep holding the button it keeps vibrating. I can enter fastboot mode by holding the volume button and connecting to the computer, computer installs a driver, but then it doesn't recognise it anymore...
HELP

Just an idea but try this, open the sim card tray and use a pin to press the red button and after that wait for 1 minute at least and first hold the volume button down and then while holding it, hold the power button too for 5~ seconds iirc. Or wait upto a minute and see if it triggers.
Delete my post pls
Isn't that you need to hold volume - and connect to usb to get in flashmode?

already tried that, it will directly go to TWRP recovery menu by pressing volume down key and power button. By holding volume down key and connecting usb it will turn on flashmode but that did not happen any more.

yah but that option was not working after recovery flash and unable to turn on flashmode by pressing volume - key and connecting usb.
Does anyone know the solution to this? I'm stuck with a soft bricked xperia M2 D2303, bootloop and can't open recovery mode. Tried to connect to PC and run flashmode, but not working, I'm just getting a green blink, not the solid color for the LED.
It does run fastboot, but no flashboot. Any ideas?
PS: I have no idea what my IMEI is.

For the Flashmode, the green led has to blink one time. So that's normal.
And did you installed Flashmode drivers?

Can't flash TWRP through Odin.

Hi, I've been trying to flash TWRP to my phone in order to root and install some custom roms but there is a problem. I boot into download mode just fine no problems I connect my phone to my PC via USB cable and Odin recognizes my phone I untick auto reboot choose the correct TWRP file and start it and this is where it all fall aparts. My phone doesn't restart on it own, it just keeps staying on the downloading please don't turn off the target screen. I tried all the button combinations no luck phone doesn't restart. Only combination that works is volume down and power button but that just shut downs the phone. I really need some help here guys. Thanks in advance
after flashing TWRP, hold down volume (-) and power button, do not release until you start again... when you start, change volume (-) button to volume (+) for a few seconds and release... then start twrp
After flashing TWRP, disconnect cable, hold Volume DOWN and POWER button and once the screen is OFF, press and hold POWER + Vol UP + HOME.

Mi Samsung doesn't turn on!

I rooted my phone yesterday, so today i wanted to install twrp, but when i turn off my phone and tried to go unto recovery menu the logo just turn green and and the screen went black. I tried to start the download mode but is no answer, so i thought that the phone was bricked, but when is bricked you can access to the recovery mode, all i can do is press volume-down + power-btn and there i got the samsung turn on logo but then i have the same green logo and the black screen again.
Somebody can help me pls!!!
Try this: Connect usb with pc. Hit volume down + power button till screen goes on and at the same time screen goes on release power button and hit and hold volume up and down button, this should get you into download mode and flash stock firmware with odin

Question my Galaxy A12 won't boot to android or download mode help me pls

so I just tried to install unofficial TWRP 3.5.0 on my Samsung galaxy a125m and everything went fine, Odin said done. Then I just tried to start TWRP by pressing power and vol up and it didn't start, so I thought I might have done something wrong and rebooted to download mode and flashed it again, Odin said done, then I unplugged the USB cable and now it won't boot, neither to the system or recovery, even to download mode, it did enter download mode a few times before but I pressed the wrong button and had to cancel and enter again, now it won't even enter download mode so I can't flash stock rom to fix bootloop... pls how can I solve this I'm desperate
when I try to enter download mode by pressing volume up + volume down it just shows up charging mode without any numbers, then it turn on and shows Samsung logo, unlocked bootloader warning screen, and the Samsung logo again, but then just restarts and repeats all again...
when I try to press volume up + volume down + power, nothing really happens...
someone help me please
You need to keep both volume up and down pressed, then plug in the charging cable. It should enter download mode, no need to press the power button like in older samsungs.

Is the cable plugged into a charger and on?
Have you considered that your volume buttons may not be working?
Same hear
Try attaching your phone to the PC, and then pressing volume down + power to reset the phone, (for about 7~8 seconds) then immediately press the volume down and up buttons, that's how I recovered from it. Tell me if it worked

Please help it dosent worked
No pc detection
No download mode
No recovery
No charging
Hello, unfortunately in these cases the only solution is to enter download mode, check if any button is damaged or if the cable works and if it is well connected, press the buttons harder, hold down the volume up and volume down buttons at the same time , by pressing the strong buttons, for about 6 seconds and then connect the cable. If you don't try another cable to see if that's the problem there is no other solution as the phone is not recognized by an app that can put it into download mode when turned off the solution is the one I already told you about. I hope you have fixed that problem. Sorry for my bad English.

I am having a similar problem with the Samsung A12 SM-a125u
I never could enter into this "Downloading mode".
I tried flashing the stock ROM through ADB with fastboot, and I have another problem that I've never seen before: ADB can see the device while in recovery mode, but fastboot can't. And so it won't allow me to flash the ROM and I don't even know how Odin is supposed to help yet; I think I needed to enter Downloading mode for that, but I can't get into it.
I'm working on this phone for a friend who was given it because his friend's mom doesn't remember the password to it. Does that matter? It's worth noting that because of that I cannot get in to turn on OEM unlocking or dev mode, but idk why that would come into play in recovery mode. Also, the model indicates this is an AT&T phone, and tutorials online have acknowledged this model in their "applicable models" list at the beginning of their tutorials, but I know that carrier phones can cause problems all over the place (stop buying carrier locked phones people!); is this a problem?
How the heck do I flash the stock ROM to this this?
