HTC Desire 820 bricked - Desire 820 Q&A, Help & Troubleshooting

Hello today i wanted to root my phone, but it was in twrp bootloop, now screen is off and orange led is lighting.. My PC doesnt recognize even phone.
When it's plugged to charger/pc it's showing battery with lightning.
Edit:
Now it's stuck in HTC White logo screen.. And PC recognize phone, but when i want to go to bootloader/recovery it's showing:
"Error device not found".

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.

HTC one x bricked need help...

I just flashed a arhd rom a kernel and InfinitySound mod and then my phone was stuck in the htc quietly brilliant screen...
The main thing is i can't even enter the bootloader with "vol+power down" help please...
Keep pressing the power button for more then 5 second and you will see the 3 buttons blinking. After that phone will restart and then press volume down to enter in hboot.
Then look on xda a tool with witch you will flash a stock kernel.
Perhaps this is the solution for you

i tried it, but no luck... it still boots into the htc quietly brilliant screen.
Hold the power button to force a reboot. As soon as your HOX powers off press and hold vol down, keep holding until you enter hboot. It might take a few attempts
First boot can take awial I don't think your stuck its just loading

It's stuck not loading because I have waited 10 hours already. Also, I keep trying to get it into boot loader , but to no avail... tried 30 times already...
Without getting into the bootloader, there's nothing I can do...

Does your phone keeps rebooting?
If so, it sounds like you haven't flashed the correct boot.IMG
You need to flash the correct boot.IMG that is for the kernel you flashed.
-----
As for boot loader, why don't you just use the adb command?
adb reboot bootloader
As for the button combination not working, you need to hold both power & volume down at the 'exact same time', and don't release them until your boot loader screen shows - even if it does an extra reboot, keep them held!

I am having the same problem, and i forgot to backup my previous rom. I rooted, and unlocked my phone, then i tried to install the rom, it installed. however now it just stays in the spinning loading sign for CM10. Is there anyway of putting another rom on the >fake, ie internal> sd card, which cant get removed from the acctual phone? so then i can install that rom? i have tried reinstalling the rom but that didnt work
Click to expand...

If you have cwm 5.8.4.0 you can mount the sd card as usb drive.
Don't forget to flash the boot.img that goes with the ROM.
fastboot flash boot boot.img
You are probably forgetting to flash boot.img using fastboot from your pc, from your description. After flashing boot.img, issue a
Fastboot erase cache
Or you will most likely get bootloops.

I've had similar issues earlier today. Read my thread, maybe it'll help.

EDIT: If the screen 'hangs' press power button + volume up, wait for the screen to turn black and press volume down. That should get you into your bootloader!

I wanted to flash to the UNROOTED Google Play Edition...so I rooted, TWRP'ed and did the S-OFF

so I tried to change the ModelID in the android.txt file...flashed, and then my HTC One M8 kept going into the HTC logo screen with 4 triangle error screen
When I do fastboot oem reboot, it gets me back into the device - but any normal restart after, and I'm back in the HTC logo error screen

Have you tried flashing a stock recovery via fastboot? Or flash TWRP again then flash a stock nandroid backup from the backup/recovery thread?
m8 white screen
Good evening community
I think I bricked my M8. Tryed to flash a custom ROM, unrooted and installed it but didn't liked and decided to go back to stock ROM. Went to TWRP and wiped one position more than needed - data. So now my M8 booted just into white screen with HTC logo, power off doesn't work at all, hard reset combination doesn't work, power on + volume up - doesn't work. It's always on and CMD says <waiting for device>
Who can help me?
Thank you in advance
Edit: got into bootloader, thanks to Niorun post edit.

For this phone, as long as the screen comes on, its almost certainly not bricked.
Being stuck with OS not booting is a common thing when flashing ROMs. It just happens from time to time for one reason or other. Folks that freak out about this (and think their phone is bricked) need to relax and learn some basic recovery steps.

Wiping data will not make the phone get stuck on the HTC logo screen. Wiping data just erases user data. So the phone would have just booted into the OS, but with no previous user data present any longer. Failure to boot was for some other reason.

Power + Vol Up reboots the phone, this should always function as long as the screen comes on.
Power + Vol Down to boot into bootloader similarly should always work as long as the screen comes on. Failure to do so is almost always a matter of user error, not performing the button combo correctly (either not pressing vol down fast enough, or letting go of it too early).
Power + Volume Down
So, in response to

Pressing Power + Vol Up does show the HTC screen for me, then it goes black.
Pressing Power + Vol down doesn't do anything.
Am I following the instructions correctly?

Try it this way:
1) Reboot the phone using Power+Vol Up
2) The moment the screen goes dark to reboot and before the white HTC logo screen appears, let go of the buttons, and hold the Vol down button. Do not let go of vol down until you see the bootloader screen
3) If the bootloader doesn't appear, you either started pressing Vol Down too late, or let go of it too early. Just do the steps again until you get it right.
Clarification
I have to anticipate when the screen is going go from black to showing the white HTC logo? Then do vol down then?
htc m8 brick
i too am having issues with a bricked htc 0ne m8. We purchased the phone as-is really cheap. its freezes while booting up. i can get into fastboot and recovery just fine. i have been successful in installing ruu files but the ruu file doesn't fix the "boot loop" freeze at startup issue. The device is s-on still which sucks because i can't find a method of achieving s-off in fastboot mode. i was able to unlock the bootloader, hoping that it would help and now the ruu files won't work anyone. now i can't get the bootloader to lock through the method that htcdev.com tells me to use. ive also tried to install update through adb sideload through recovery without success.
so i have a s-on, unlocked bootloader htc m8 that i still can't get it to boot up.
any help would be appreciated.

I just timed it (in my head, not with a stopwatch), and you have about 3 seconds while the screen is black, before the HTC logo screen appears. Plenty of time to let go of the power and vol up buttons, and hold the vol down button.
The reason I say "the moment the screen goes dark" is that some folk wait too long, and start pressing vol down when the HTC logo screen is already up. By then, its too late.

Need more info.
What hboot number?
What radio numer?
What CID (or original carrier version)?
What RUUs did you try?
Don't know what method HTCDev says to relock the bootloader, but as long as you can still get into fastboot mode, its simply the command: fastboot oem lock
Also, there is no other currently working s-off method aside from sunshine (which requires booting into OS) so you can stop looking for one.
I "Softbricked" my htc one m8 AT&T
i recently rooted it and made 4 back ups. I deleted two of them and tried to roboot to fastboot. but it says 'No OS installed" . My computers reconize it as a disk drive and when i click on it, it asks me to insert a disk...Please, ANYONE with information that will help, share

Download a ROM on your PC, transfer it to your extSD, put that in your phone and flash it in recovery.

Well, you say you can't get in the bootloader or recovery, have you tried to hold down the power button and volume up button, and then when the screen goes off switch to power and volume down? That should take you to your bootloader! If you can get there I would guess you would have a backup in recovery

It doesn't. The tool is very outdated, and I typically (virtually always) recommend against using it for that reason. The toolkit uses the old firewater s-off method, which hasn't worked since December 2014.
When I said there is no other working s-off method besides sunshine (and to stop looking for one), it was a statement of fact, not a guess.
I need some help, I have a m8 rooted and to make an update from htc (I have te stock rom) I have flash de stock recovery (te old one was the twrp) but now after the update de phone is stuck in the htc logo, I can enter in the fastboot but I dont know what to do and what direction I should take
Follow my steps if your phone is not booting up.
1. Lock bootloader if you have unlocked bootloader.
2. Download HTC One M8 4.16.401.10 Stock Lollipop RUU [0P6BIMG] ( search google because I can not post link since I am new forum member).
3. Rename the downloaded RUU to 0P6BIMG and send the zip file to your phone SD Card.
3.Reboot your phone in to the bootloader mode by powering off the phone and rebooting with Power button and volume down or use fastboot mode command : adb reboot-bootloader.
-This way our phone will automatically detect the RUU file that you pasted in SD card (step 3) and flash it.
Your HTC One M8 is alive

The advice given here is good, except it assumes too many things. There is the assumption of S-On, and of current firmware version. Also, if you are using ADB to reboot to bootloader, the user might as well fastboot flash the RUU.zip, or run the RUU.exe that is also available.
@W_KuP, Post the results of fastboot getvar all (edit out your IMEI and serial# ~ that's private info)
If you are indeed on WWE/International firmware, that RUU.zip will work for you. Download link here.
If you are S-On, you will need to relock your bootloader first. In fastboot: fastboot oem lock. If you are S-Off there is no need to relock your bootloader.

even i am stuck in this mode, after the 3rd step from WinDriod Toolkit flashed supersu, returned to install Lineage OS from TWRP mode, was sucessful in that too however forgot to install GAPPS after that and proceeded further, phone asked that super su not installed and if i want to install one now, proceeded from there and the screen now shows a 'sad Teal colour smile',

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 bootloader.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. 1. https://yadi.sk/d/nWnRAChBnEtxG 2. http://forum.xda-developers.com/desire-820/help/update-modified-5-0-2-euro-firmware-t3376130
Simply Google UPDATE-unSU.zip and download it... Place it in ur internal SD and flash it in recovery... It will unroot ur phone... It's so simple.. ?

Tighten the two volume buttons and the power button when a black screen appears to hold the volume- button and power, smart mustget into in the loader in the boot loader to choose reboot (assuming that the system is not removed)

The phone is still restarting after selecting reboot also.
Can you boot into recovery?
Most likely you have a corrupted boot or system partition.

I don't know. The phone was working perfectly. Just a day ago I got a marshmallow update. I installed it. Then after 2 days, I wake up and find this.

I know this is an old thread and was left unsolved quite some time ago. But you must have found a way out yourself after not getting a solution in this forum. Could you share that with me please? I am having the exact same problem!
i have this problem too . please help me
i'm reflash stock frimware but phone boot loop .help plz
I'm having the same problem. any solution guys?
To all who has this problem, please do try to boot into custom recovery (if installed any) and wipe cache and davik-cache. If it still fails, please replug the battery, it should reset the boolean, and if it still fails, an RUU flash is the last resort before hardware issue.
Dear Friends,
if you have same problem with your HTC 820G Duel SIM ( after OTA Update of 6.0.x OS ) please call HTC toll free No. 1800 266 3566 ( Only for India )
even your Hand set is out of warranty,
send Email to them Because when i call to them they say you are only one who is facing this issue ( when i ask then to downgrade my OS to 5.x.x )
service center simply say Mother board problem and ask 9500/- for mother board or 173 /- as diagnostic charges
so please call to get your HTC working with proper OS
my phone is working properly just before 6.0.x OS update....
hope so no. of calls can make them realize real problem with there OS not in hardware
THIS IS THE ONLY WAY TO MAKE YOUR PHONE WORK calling HTC Customer Care Or Email ( i tried every thing posted in this web site but its restarting & looping... for all stock OS and CM13 and All other Nice OS / all recovery TWRP and Flashing tools i used but no luck...
