I have TWRP installed, and have managed to run it a few times. Now I cannot start TWRP at all.
From off, if I switch on, the following happens:
1) Screen with Samsung Galaxy A70 - Secured by Knox
2) 0.5 seconds later another screen, "this phone's bootloader is unlocked and it software integrity. .." and "press power key to continue..."
3) 5 seconds later, same screen as (1)
4) 3 seconds later, red letters "this phone is not running Samsung's official software"
5) 3 seconds later blank screen with "samsung" and then booting to android.
In my experience I have to flash twrp every time I want to use it( I don't know the reason but I couldn't fix it ) , for booting twrp on the other hand I turn off the phone first, then I press power button+volume down until the "this phones bootloader..." screen appears, here is the tricky part, you have to quickly let go of these two buttons, press power button, let go of the power button (after the warning disappeared) and then press volume down button (and hold it) until twrp logo appears, this happens really fast so you may need to do it a few times to get used to it.

Yes, same here, the only time I have managed to run TWRP on this phone, is right after a flash.

Power off the device, plug into a pc, wait for it to start charge, hold vol up and power till it turns on. Wala boots to twrp. If you have magisk installed,you can use the reboot option within magisk.

Samsung changed how to enter recovery on Android 11. Power off device, plug into pc, wait for it to charge, then hold vol up and power till it turns on. Alternatively, if you have magisk installed, use the reboot options within magisk.
I did that. Thanks!
But it has gone to:
Android Recovery
Samsung /a70qxx/a70q
11/RP1A.200720.012./A705FNXXUB5DVB3
user/release-keys
Use volume up/down and power.
Reboot system now
Reboot to bootloader
Apply update from ADB
Apply update from SD card
Wipe date/factory reset
...
...
...
Where is TWRP? It seems it's gone.

That's because you're not installing it properly go back to my guide and follow it exactly and stop listening to these other people. I've been modding this device since it first came out with Android 9, I know every inch of this device. You're getting confused by what other people are telling you

It fails here, on this step. After successful flash of recovery.tar, power + vol down to reboot, cable still connected, nothing you can do now can bring TWRP up. The phone boots into Android.
EDIT: I think I have now got it. I will update in a few mins.

After successful flash of recovery.tar, power and vol down to reboot, as soon as the phone screen goes blank, immediately release all keys and press and hold vol up. Must be as soon as screen goes blank. The device will then reboot twice and land you in twrp splash screen. You must hit vol down and power after successful flash then when screen blanks, vol up. If you miss this step, twrp will not hold and revert back to stock recovery.
Here is the notes I made today:
****************************************************************
INSTALL + START TWRP
phone is off
press up + dn
insert cable
go into download (press up)
ODIN 3.14 + AP:tar(vbmeta.img+twrp.img), auto reboot off, press upload
when it succeeds, press dn + pwr until it reboots
then quickly up + pwr until it starts (no need to hold down)
this starts in TWRP
from powered off
press pwr button
goes into twrp or android(system) -- depending on what was used last time
if we used reboot->system last time it will now **Always** go into system!
to go back into twrp:
switch off
power cable until charge
pwr + up until it starts
****************************************************************
The above means that you CANNOT go back to TWRP unless you have a cable and a PC near by.

1. Unplug phone - VERY important
2. power on phone, doesn't matter if it is boot looping or whatever
3. hold vol up and power EXACTLY 10 seconds
4. let go of both
5. hold vol down and power till boot loader comes up.
You have no charge because you are running an old ver of twrp, get 2.7.1.0

Share how I fixed my HTC M8 with the same problem.
Hi,
I just want to share how I fixed my HTC M8 with the same issue. The method is the same but a bit different. I found the solution from googling the below link:
http://forum.xda-developers.com/htc...ter-download-mode-t2853100/page2#post62490577
The essential method is to keep holding down the power button and don't let it go while pressing on the volume up button to reset. At the very moment before the phone resets and shows the HTC logo white screen, switch from pressing the volume up button to the volume down button while holding down the power button. Or you can count 10 seconds and switch before the screen resets.
I hope this helps other people with the same issue.

Thanks, the pwr + vol-up 10 seconds before the phone hard resets, them pwr + vol-down got me back into hboot and recovery and then out of a build.prop issue.
I have no idea why this is a thing: Getting into the boot loader is usually easy. I can't imagine why when the system doesn't boot normally that the standard procedure to enter hboot changes.
regardless of retarded engineering on qualcom or htc's part, thank you an0ther.
Here's what I did:
Had everything running fine with twrp installed and rooted.
Booted into twrp.
Wiped cache system and dalvik.
Restart.
Device wouldn't boot or go to recovery.
Attempt to follow THIS
Process fails.
Unplug device as instructions say.
Device battery dies.
Device will no longer boot into anything, including download mode.
Help?

Make sure your device is fully charged and turned off.
Simultaneously press and hold the power and volume down buttons.
When the LG logo shows up, release the power button only.
Now press and hold the power and volume up button while keeping your hold on the volume down button.
When the factory reset screen appears, release your hold on all buttons.
Press the power button to continue.
Press the power button again to confirm if you’re sure you wish to continue with the reset.

Try holding down the power button for like 30 seconds.
I tried flashing ViperOneM8 1.8.0 (ViperOneM8 1.7.1 -> 1.8.0) which I guess was the wrong thing (I think that was an update, should have started with 1.7.1 first). Anyway... Now my M8 boots to some type of android base OS without a lot of things...
1) It's not possible to get to settings as there is no settings app in the app drawer.
2) There is no title bar/task bar at the top. The area that holds the time, and a few icons at the top is gone.
3) There is no background.
4) There is no way to get on the WiFi do to #1 and because of this I can not add my google account. That in turn means no google play store access.
But the BIGGEST thing of all... I CAN NOT BOOT TO FASTBOOT!!!
- Power the device off.
- Hold the volume down button (also tried the volume up button) + press power usually boots strait to fastboot mode.
I THINK it has something to do with the fact that by default in the settings I need to untick the fastboot option in the dev options.. Well I can't get to settings. Now what?

Shut down phone.
Turn it on
Hold volume up+power button until it restarts
As soon as you get the black screen for restart release power button and hold volume down.
If your timing is right you will enter bootloader.
I tried it and it definitely works
Flash your nandroid or any rom you know was ok to begin with and you are up and running!!!

Tried that...
1) Powered off device.
2) Held power button for about 2 seconds until it came on then let go.
3) IMMEDIATELY I pressed and held down the power and volume up buttons.
4) The phone continues to boot up a little bit longer and gets to the verizon check (verizon splash screen) then shortly after goes black (as expected).
5) IMMEDIATELY let go of power button continuing to hold volume up button.
... .. .. .
6) I get the white screen that says HTC (powered by android)... NOT a bootloader screen as expected.
Update... When I try to click on the app drawer then top right click the little three dots, I try and "Manage Apps" ... ERROR "App isn't installed"...
:/

If you connect the phone to the computer, can you get fastboot or adb to recognize the phone?
If so, you can try adb reboot bootloader command or fastboot reboot bootloader comand

Yea, I ended up doing the following...
1) While device is powered on, Press and hold Volume Up + Power until device reboots.
2) When it starts to reboot continue holding the Power button and change to the Volume Down.
That worked for me.
Hello
I was updating from a M version to another M verions. But I had to use the temporary recovery method.
This is what I was doing but didn't finish properly
Requirements:
1. Unlocked bootloader
2. TWRP for Z00A (Download | How to Install TWRP)
Unlock Bootloader on Android 6.0 Marshmallow ZenFone 2 ZE551ML/ZE550ML
Download tool (Download Here)
1. Extract it and connect Zenfone 2 with laptop/pc
2. Click unlock.bat will automatically detect whether the adb or fastboot mode, and then reboot into bootloader
3. Will appear on the screen to unlock the success of mobile phones after five seconds will reboot, then hold volume up the phone automatically re-boot back to bootloader.
4. If you missed the previous step, press the power button for 10 seconds off, then press the "Volume Up" and hold the power button to boot into bootloader.
5. After the phone has successfully re-enter the bootloader, click restore.bat on the computer, where the restore refers to the restore Android ifwi 6.0 otherwise Android phone can not enter the system.
6. The phone will reboot and restore white on black ASUS logo screen, and then enter the Android system.
Click to expand...
Click to collapse
I extracted and connect my zen2
Ran the unlock.bat
The phone entered the bootloader, flash his things and boot again but on the white screen
Then I had to hold power button 10s to turn it off and turn it on again
Entered the bootloadr by holding Power+Vol UP then to recovery.
At this time I just used the recovery as I usualy do, Wipe everything, cache, data, etc.
Connect to the PC, put the new UL-Z00A-WW-4.21.40.184-user.zip there and flash.
BUT now that comes the problem. I select the option to boot it after finish flashing.
So obviously I didnt finish the steps mentioned on the quote above.
I didnt ran the restore.bat before reboot into system and now All I see is black screen.
I've tryed some steps of those tutorials for briked phones but My computer can't see the device for long enough
http://forum.xda-developers.com/zenfone2/help/thead-bricked-phone-updating-to-mm-tips-t3452785
I try to do those steps but I'm stuck on this part
now back to the Zenfone 2, hold power for 20 seconds to shutdown, then press simultaneously the key "power" + "volume down", until phone vibrates. Or computer makes detection sound, wait a few seconds it will add an item immediately below intelSoC in device manager “MOOREFIELD” new devices is successful.

My phone doesn't boot even on bootloader. It just vibrate twice and then nothing happens.
On my device manager I can see the "Moorefield" but only for a brief moment. when I try to turn on the phone then it immediately disapears and repeat this process (Vibrate twice, long preiod doing nothing and still black screen, then vibrates again twice, repeat)
Any suggestion?
Thanks in advice

any luck fixing? i got the same result, no screen or anything, two vibrations since yesterday
Sadly, no.
no fix for me yet...
Let me know if you find something
You have tô unbrick your phone. There are some tutorials in the forum
I am using the Z008D variant of the Zenfone 2.
I had bricked my phone 3 times and the guides that had helped me are:
https://forum.xda-developers.com/zenfone2/help/thead-bricked-phone-updating-to-mm-tips-t3452785
https://forum.xda-developers.com/zenfone2/general/guide-brick-soft-hard-bricked-zenfone-2-t3284256
I too had the same problem the first time I unbricked my phone. The moorefield device would show up briefly in device manager. It is stated in the guide that you had to press power+vol down when connecting the phone to use xFSTK. I googled and found that you had to actually press and hold the vol down button only and then connect the USB cable, then release it when the moorefield device is detected.
So I wanted to root my device, and i did the steps till i flashed twrp(unofficial one for a50), i was at this point: To get out of Download mode and Enter TWRP Recovery mode: Press and hold Volume Down + Power key, when screen blanks release Volume down only and quickly press Volume Up key. As the screen blanked out i also accidentaly let go of the power button... bootloop since... I can't do anything, can't use recovery, can't use download mode, cant connect to it with my pc using a cable. so either i wait till the battery dies or i find another solution...
1. Unplug USB cable from phone.
2. Hold down power button till it shuts off
3. When it's off, hold vol up + vol down & Press power
4. It should boot to download mode.
5. Load stock rom for your model (Check the variant to make sure)
6. All is back to normal again.
