[Q] EVO Cannot boot normally or into recovery

I am using a rooted EVO 4G gingerbread with clockworkmod
Current symptoms are as follows:
Boots into a blank screen (backlight is on, but nothing on the screen at all)
Vibrates once you turn it on, but nothing after that.
Stays there until I pull the battery.
Occasionally vibrates twice and a green light will start to blink above the screen.
Tapping power still toggles the screen and backlit buttons when in this state.
Throughout today it's gone through several different symptoms.
At first it was stuck on the quickboot screen doing nothing, but the buttons were completely unresponsive. It would sometimes also constantly vibrate. I took out the battery for awhile and it would just show the screen again when I put it back in and tried to boot.
When I got home later that day, it stopped doing that, but just would refuse to boot at all. It would sometimes show the white screen and just be stuck there unless i pulled the battery out. Now it's doing the symptoms I posted in the beginning.
Any ideas on what's going on and how to fix this?

Can you get into Hboot? If you can you can RUU and hopefully that will do something.

Thank you for the reply
No I cannot get into HBoot, it literally just boots up (whether or not I'm holding the volume down button or not) into the blank screen I described.

Turn off your device and then remove the battery AND the SD card. Wait about 30 seconds and then re-insert the card and battery. Now simultaneously press the DOWN volume button and the power button until the device starts. You *should* be taken to the HBOOT screen. If so, select 'recovery' from the menu and then go from there. I suggest a re-wipe and re-flash of your rom.
If you still cannot get to the HBOOT screen or recovery, download one of the RUUs from my signature, specifically one with an .exe extension and run it from within Windows while your device is connected to your PC via USB.

Still nothing. Thanks though.
I think I have to just return and get another phone... I haven't seen this error anywhere. I removed the microSD card for about a minute, put everything back in, still tried to boot in recovery (vol- and power) didn't work. I tried one of the RUU .exe and no good, when the phone was on, the program didn't recognize that my phone was there or something. Afterward, I tried the other RUU link where you have to drag files, coudln't see anything when I tried to boot in recovery still.
This is looking like i have to get a new phone

new symptom. Just vibrated 5 times. Longer than normal too.

HELP
Reioumu, what did you do?

same symptoms...with 5 vibrations and need for a battery pull.

I can get into hboot (by pressing vol-down + power)
I cannot get into recovery.
It splashes to the white htc evo screen, then flicker of the LED, 5 vibrates, and a black screen.
i was backuping my system using ROM MANAGER. When i turned on the phone, it couldnt detect the SD card. When i rebooted all the issues you described started to happen.
I'm at wit's end. I did a bunch of googling on the issue. "vibrate 5 times black screen evo" and there seems to be some sort of fix but i dont understand how to implement any of it. I got as far as installing the Android SDK but cant get fastboot to work. The issue seems to be with the USB port AND the SD card detection.
I was planning to just give up and give it to Sprint to fix but the rep said i need to unroot it before i send it to them. [email protected]#[email protected]#. I cant do that without recovery!

[Q] Htc one m8 black screen, won't boot up PLEASE HELP

So, I tried to restore a backup from TWRP. During the process, the system and cache were restored fine, but couldn't restore the data (for some reason, it said failed), so I figured it's alright, I'll just have to install all the apps again, no big deal. But, after I clicked the "reboot system", the screen went off and never turn back on.
I can't get in bootloader screen in any way, I haven't tried the Vol up + power button for 10s, and the vol down + power button, and the 3 button all together... Nothing works.
When I press the power button normally, nothing happens, not even the Htc logo screen.
When I plug it in, it only shows the battery charging icon. So I tried the buttons combination again (coz I thought at least the screen turns on now), but still, nothing happens, just the screen switch between black and the charging icon.
So, I left it charging overnight, and tried the buttons combination again, nothing works still.
Now I have no idea what to do, can anyone please help me?
Htc one m8 international
Rooted, TWRP recovery, S-ON

It sounds like you hard bricked your phone. Try using this guide youtu . be/ rpA71FXddyU[/ but Im not sure it will work.
Only thing what you need is that computer recognize your phone, because when It doesnt then you should take your phone to local phone repair.

HTC M8 stuck problem.

I rooted my phone like a month ago and installed TWRP. After ARHD i wanted to try MIUI, but when i flashed it i lose my root. I m downloaded ElementalX 4.4 gpe kernerl and i go to flash it, instalation go normaly, but when i finished twrp lagged for first time 2,3 secunds when i tap reboot. After that, phone booted normaly, white display with htc and developer text, like always, but after that come black display. It stucked here and i cant do anything. No matter how long i hold power button or anything else it cant do anything. It dont shows orange light on charger. 2 hours i cant do anything, but phone is running something, it is hot right now, cca 41 c, but its still stucked. Please help.

a
finded out now, when am hold power buton + vol up, phone just restart, and stuck like last time. It cant boot to recovery or bootloader

Hold power + volume UP, as soon as the screen goes BLACK switch to volume DOWN. Keep the POWER button pressed at all times.
That will put the phone in the bootloader, go from there to the recovery and reflash a rom with a FULL wipe otherwise it will never work.

Probably hard bricked - not sure

Hi,
after running a rooted Kitkat for a year or so I thought I wanted to install CM12.1. So I wiped and flashed via CWM Recovery and also flashed some GApps (probably the wrong one). After flashing (with confirmation that everything was successful), I wanted to reboot but after clicking on reboot, the screen just went black. Waiting for 5 mins, nothing changed.
Pushing the Power-On button lets the phone vibrate once, that's it. Pushing Vol+ or Vol- together with Power-On does not change anything. Connecting a charger to the phone, let the red LED flash once.
What can I do to revive my phone....?
Suggestions or hints are greatly appreciated

Try holding power and volume up together for 8-10 seconds, just to make Sir it's totally powered off, then connect the charger and see if it starts charging. Older batteries don't do well in this phone. It wseems to me you might have had the sudden-battety-drain phenomenon when you flashed.

Thanks, that seemed to have work. I am now a happy user of CM12.1 on my Xperia Z1 Compact

Phone boot up, but the screen remains black

So I was trying to flash the VF version of Ressurrection Remix, ended with a fail because I have no idea how to upgrade to mm blob since I have downgraded my self long ago, so I deleted all partition, and restored my previous backup.
But strangely my phone is completely black, first thought my phone is bricked, but it's not, going to fastboot mode, screen won't turn on, same as doing normal boot, scree remains black, but when I turned off the phone and plugged in to the wall charger, the screen turns on and show battery icon in it.
So I tried to do a normal boot while the screen is black after trying to boot into fastboot, keep waiting and finally there's a vibrate, and charging LED light up, pressing the power button will vibrates and I'm assuming that's the power menu, long press the power button will turn on the flash, so my phone is working but only the screen went black!
and this is not a brick, I have no idea what's going on with my phone, so any help?
