Rooted HTC Desire 820 Restarts continuously - Stuck in Boot Loop - htc Logo

After rooting my phone and trying to flash TWRP recovery, my phone is now stuck in a boot loop - Htc Logo.
I tried holding down volume down and power button but it does not enter recovery - continues loop.
I tried volum up and power and all 3 buttons pushed as well but stays in bootloop.
I think i might have erased the stock recovery that was on there..
What can i do to fix this?
Please help me as soon as possible
Tighten two volume buttons and the power button when you see a black screen and holding down the volume- and power button that would go to zagruzchik.Telefon must be connected to kompyuteru.Esli got to go to the boot loader, boot into download sistemu.Esli not work then you have forgiven stock rekaveri of loader. https://yadi.sk/d/nWnRAChBnEtxG

Hi... Thanks for the reply... I tried again but it is still in boot loop - it does not go into boot loader...
Any suggestions please help me
flash stock through TVRP rekaveri. 1. Wipe-advanced Wipe - note 5 crosses (micro SD card is not necessary) Swipe to wipe 2 flаsh stock rom 5.0.2 https://yadi.sk/d/nWnRAChBnEtxG 3. Follow the advice of 1 (Tighten two volume buttons and the power button when you see a black screen and holding down the volume- and power button that would go to zagruzchik.Telefon must be connected to kompyuteru.Esli got to go to the boot loader)

Need some advice....

I tried to root my phone and followed all steps until it asked to boot into the custom recovery and that only displayed a blackscreen and if I tap on the screen the phone vibrated. I cannot boot into bootloader as the phone just automatically tries to enter recovery with blackscreen.
Hold all buttons the phone boots normally and can use the phone as usual.
I've tried to use the adb and fastboot cmds to restore and factory reset but just reboots and tries to enter recovery with the blackscreen.
My device is htc_a51ul if that helps.
Thanks,
Phatzy

I think you have flashed a wrong recovery ,first thing to do now is flash stock recovery and whether if it is working fine if so then flash the proper version of twrp 2.8.7.0 is recommended and see if it works
I had the same issue when I first flashed twrp on lollipop but then I did the above and now everything is fine.
while its on the blackscreen only adb commands work. If i try fastboot commands its just waiting for device and phone dont respond. I cannot get into bootloader at all with volume keys or with adb command.
Many thanks for suggestions.
Ok I have now managed to get bootloader back and I can now enter the stock recovery but when I enter recovery it has a red triangle. Is there anyway to remove this?
Thanks.

Stuck in recovery after ADB with broken power button

Its very complicated. My T705's power button was damaged by water. And i flashed Stock MM rom with odin. It was fine after flashing, the tablet boot into the os properly, work very well in the os.
But then i want to wipe the cache and data after that, so i was using the code"adb reboot to recovery" to get into recovery mode because my power button was broken. (I thought it can be using home button to select in recovery mode)
But the nightmare is i can't select anything in recovery mode which requiring a power button. So i can't wipe the cache, also can't select the option to reboot my tablet...... I've tried to hold both the volume down and home key to go to the download mode menu, and select restart by holding volume down, but it go to recovery again even after removing the battery, i think it's because the adb command.
And the strangest thing is i can't use my volume up button in download mode menu, so sadly i can't flash the rom again,:crying: but the volume up is working well in recovery and in the os......
Is there anyway to prevent the tablet to boot into the recovery again? I'm quite sure it's not the problem when flashing MM rom, the problem should be the adb command makes my tablet boot into recovery until i change the boot setting in recovery mode.

That would only work if you could actually use adb.

Holding vol down + home key can boot to the download mode menu.
But the device will automatically turn on after inserting the battery, no need to press any button, but the device only boot into recovery after i use the adb boot into recovery command.

If that's the case that means the power button is stuck on or you wouldn't be able to power on or boot to Download mode.
All you need to do is flash the stock firmware or twrp and it will reboot back to the OS.
Hopefully I've got your fix:
When you insert the battery your device boots up, if so, insert the battery and press the correct key combo while the splash screen from logo.bin is showing to boot into the download mode.
After that flash TWRP latest version with Odin. Then when your phone again boots to recovery, chose Reboot -> System to boot Android.
---
If the above isn't applicable and you can start Android somehow, I will download either FlashFire or MobileOdin to flash another recovery/ROM.

Bootloop even when in recovery mode

Hi guys,
I have a nexus 7 2013 which boot loop (or any watchdog restart ?).
If I try to normal start this one, I will get the Google logo for few seconds, then it will restart on its own.
If i press the volume down during this process, I can boot to bootloader, but same way, after few second, device will restart.
Any clue on what can be wrong ?
Thanks

Hello, connect external power and try again. If it works now, you will have to replace the battery.
If it does not work with external power and it can not stop in bootloader/fastboot mode, then the hardware is faulty or the bootloader is corrupt.
External power does not change anything. Still boot loop, so really should be a hardware issue.
If I keep volume up key pressed, it boots, but almost unusable if I have to continuously press the volume up key.
Same when in bootloader: if I continuously press the volume up key, it does not reboot.
I've tried to erase everything with fastboot, but cannot do most of the operation. When trying to format data, it says that partition does not exists (it exists, as it can boot !)
Bootloader is locked, so cannot go with TWRP for example, as I cannot validate the on screen confirmation needed to oem unlock.
Do you know any way to unlock bootloader without use of onscreen confirmation ?
I don't know if that would help, but when I was installing Lineage OS and updated TWRP, I also boot looped once on recovery (recovery itself was boot-looping), and re-downloading (from another browser) and re-installing recovery at fastboot mode fixed my issue.
I cannot unlock the bootloader because of this issue, so cannot flash anything
Could be broken power button, if it is stuck and pressing it continuously.
Are you able to reach your recovery to factory reset?
I mean can you reach it from the bootloader menu?
If not you could try to put twrp.img or recovery.img into your PC adb&fastboot folder and try
fastboot boot twrp.img
or
fastboot boot recovery.img
Don't know if this works with locked bl
Edit: may type
fastboot getvar all
and post your result, hide your imei if you got one
