Hello folks,
I had an old HTC one M8 running android kitkat. I've rooted my phone using kingo root app then installed flashify. I downloaded the latest TWRP 3.1 and also ensure that the version was correct for the device. After installing the img file using flashify my phone restarted and stuck with a dialogue saying "Entering Recovery". I've gone through a similar post where a senior member said to hold the power button until it reboot up. That method is not working for me.
I would highly appreciate and be pleased if anyone can help me out.
Is your bootloader locked? If so, that isn't the proper procedure for installing TWRP on this device. You can't install custom recovery on this device, unless you first unlock the bootloader.
Hold power+ vol up to force a reboot (may need to hold the buttons for a minute or so in a "stuck" condition). Once the screen goes dark indicating a reboot, let go of the buttons, and only hold vol down, until you see the bootloader screen. From there, if the bootloader is locked, unlock it using the HTCDev.com process, then wipe cache and flash TWRP with fastboot.

So I'm stuck on the HTC logo (with the This build is for development message..) and it looks like I can't do anything about it. I can't get into fastboot with the whole Press volume down + Power button. Buttons are unresponsive.
adb doesn't recognize any device when I attempt to reboot the phone into bootloader with the command 'adb reboot bootloader'
Any solutions?
What I did before this happened: Ran CM 12.1 for a good month then decided to go back to stock rom. I unrooted, flashed stock recovery, and locked the bootloader (did not flash stock rom yet). I decided to try another custom rom so I went to unlock the bootloader again. All seems dandy when it starts to reboot when I unlocked the bootloader, but now it's just stuck on that screen.
Edit: I just got around to reading some guide that tells me I should just wait until the battery dies since it's likely frozen. What a bummer.

Hold the volume up button and power simultaneously (for 15 seconds) to restart the device while on the HTC logo. If you can get into fastboot mode (Volume down and power button while phone is powered down), make sure you're running the stock recovery and have locked bootloader to run the RUU.
Ok,
Was installing the viper rom on my M8, and for some reason, now my phone is stuck in a boot loop. Obviously the install went pear shaped. But now I cant even boot the phone into recovery mode.
Boot sequence now is: Google lettering appears on screen, followed by green android with the blue spinning shape in its chest, then the green android with the red triangle and black exclamation mark appears and the whole thing loops again.
When plugged into the PC its not recognized so I cant use adb to boot into recovery or try load another rom/wipe cache etc.
I've tried all combinations of power button & volume up/down to break the boot sequence, no joy.
Any ideas how to resolve, or do I have a very expensive paper-weight?

Rest assured, if the screen comes on, the phone isn't bricked.
Red triangle with exclamation point is stock recovery.
What was your exact sequence, in detail? From bootloader unlock, install custom recovery, etc.
Was the phone on Lollipop when you unlocked the bootloader?
To reboot into bootloader (not recovery, there is no button sequence to boot directly into recovery on this device):
1) Hold power and vol up for several seconds to force a reboot
2) The moment the screen goes black to reboot, let go of the buttons, and only hold vol down
3) Don't let go of vol down until you are on the bootloader screen
4) Failure to get into bootloader is virtually always user error. You either started pressing vol down too late, or let go of it too early. Just repeat until you get it right.
But from there, as mentioned it sounds like you are on stock recovery. You will probably need to flash TWRP again via fastboot in order to do much more.
Did you flash a custom recovery before you flashed the rom?? Can you boot in the bootloader mode (turn of Device completely- turn on again and hold volume down all the time.. then you should be in the bootloader)?
And your phone is not really bricked
Edit: damn to slow should not write on the phone

My friend, did you flash it using stock recovery or custom recovery? if you did flash it using stock recovery you will meet this kind of problems. I suggest you try power button and down if im not mistaken and go to hboot and fastboot usb and connect to adb, type fastboot devices in cmd if it detects your device then you can flash TWRP , find any kind of custom rom for M8 and flash it. I also assume your bootloader is unlocked and driver is installed in your PC.
Problem solved. Redpoint73's key press combination worked!

Hello All,
my phone was bootloader unlocked, rooted, installed with custom ROM and custom recovery.
Selling it to my friend, I did a phone reset in the phone setting menu.
Seems like I have done the wrong way? should have done in the custom recovery menu (TWRP)?
Now seems like I can not boot up to recovery mode anymore, by pressing power & volume down button, it always boot up straight to normal state.
Questions:
Have I lost the custom recovery?
How do I re-install? go thru ADB mode?
Thanks!
That button combo reboots to bootloader, not recovery (which doesn't have a button combo to boot directly to). Its a subtle difference (recovery vs. bootloader), but important. Its nearly impossible for the phone to not be able to boot into bootloader (if the bootloader was damaged, you wouldn't even have the screen coming on). If that is what you are experiencing (can't get into bootloader), you are probably just doing the button combo incorrectly: Hold vol up and power buttons until the phone reboots. When the screen goes black, but before the white HTC logo screen appears, let go of those buttons, and only hold vol down. Don't let go of vol down until you see the bootloader screen. If the phone boots normally, you likely just got the timing wrong, either started pressing vol down too late, or let go of it too early. Just repeat until you get into bootloader.
Alternately, within OS (and debugging enabled) you can do:
adb reboot-bootloader
or
adb reboot recovery
Now, if you get into bootloader, select recovery, and TWRP still doesn't boot. Then yes I'd recommend fastboot erase cache, and re-install TWRP by fastboot.
Pardon me,
I used the wrong term, I mean boot to bootloader.
I also pressed the wrong buttons, vol down and power instead of vol UP and power.
Many thanks for your advise.
I unlocked the bootloader and installed TWRP Recovery using the OP3 Tool. However now the phone will not boot unless I press the power button a few times. When it does boot I get the "Your device is not safe message", if I boot from here I get the OnePlus logo with the "powered by android" text but then it just shuts off. If I use the volume keys to select something else, I get nothing, the fastboot mode just gets stuck on the fastboot until I turn the device off, recovery just reboots to the "Your device is not safe screen".
Any help would be wonderful

Did you flash anything while you were unlocking the bootloader? The message is shown when the bootloader is unlocked so that is ok. Your phone, however, should turn on by long pressing the power button. You're getting a bootloop, If I were in such a situation I'd use the fastboot mode to flash the stock firmware again to get the phone working...

Awesome! Enjoy :good:
So I was trying to install TWRP on my phone. I have a Mac and was looking at some online guide. I had a pin set-up, and this is what I did:
1. Installed ADB and fast boot
2. Unlocked the boot loader on the phone
3. Check the terminal commands that the device is connected correctly
4. Had the ABD and TWRP img files on the phone.
5. Tried to fast boot TWRP.
What is happening now is that I'm stuck on a boot loop of a TWRP screen, the screen if flashing and won't load. I'm guessing to let the battery die out over night
I was looking at a few threads and some say that I should flash the factory image. Everyone is saying flash the stock file... However, I can't even get the phone to turn off or go back into bootload mode for my computer to recognize the phone.
Any tips?
Hold volume down and the power button down. Keep it held down might take sometime but you should get to the loader. boot twrpRC1 flash rc2 after getting in twrp. You could also start fresh by fishing factory once you get back to bootloader
Long press power button to shut it off
or press power button and vol down together and will take you to fatsboot mode and from there you can use volume button to seltect bootloader or recovery
I don't do pin's so I'm not familiar with the hangups involved with those and TWRP.
But I guess the first thing I'd do is remove the pin lock.
Then power down phone.
Wait 30 seconds!!!!!
Press power + volume down until phone powers on, then let go.
Should boot right into bootloader.
Fastboot boot twrp.
Install TWRP from the fastbooted TWRP.
I'm not familiar with the Mac process but on a PC we need to fastboot into TWRP from an image file on our computer first, and then flash the file on the phone.
I recommend keeping a copy of the boot signer on your device, flashing this fixes most of these types of issues I have found, especially with new rom upgrades etc.
Did you let the phone fully boot into the system after unlocking the bootloader, or did you immediately try and boot twrp?
I've had this problem twice before, both after a fastboot unlock, and I had to let it fully boot into the system before proceeding

Thank you you too. That was the problem, my patience. I didn't hold it down long enough for it to boot back into boot loader mode.

Hey I think that was it. I immediately tried to boot twrp without letting the system fully boot.
Thanks you all for the support. Go XDA!
The first question everyone should be asking is if OP was on the O Beta previously.. If that is the case Op needs to flash the factory image in both slots.
Put phone into the bootloader
Flash all bat
Put phone into the bootloader
fastboot --set-active=other
fastboot reboot bootloader
flash all bat
fastboot boot twrp
Even if OP wasnt on the O beta, this should fix the issue.
After successfully flashing Oreo, I am seeing the same flashing/looping TWRP (twrp-3.0.2-0-RC1).
Long press of Pwr restarted the phone.
Rinsed & repeat a few times.
Any thoughts to flash TWRP (temporarily)?
