[Q] Phone stuck on HTC screen and won't boot

Hi,
I rooted my phone about a year ago and recently wanted to update it and try a new ROM. Since I have no idea what the compatibility of of my old ROM I made a NAND backup then I reset it to the factory RUU version 3.29.651.5 and my phone was back to normal in the boot loader S was set as S-on.
I then proceeded to use the autoroot v2.5 in this thread: http://forum.xda-developers.com/showthread.php?t=838448. In the cmd prompt it said it was flashing the firmware, then said it was waiting for the device to boot up; however, the device did not boot up, I waited for approx 60 min and it was stuck on a black screen with the HTC logo in the middle and a small warning (triangle with exclamation point) in each corner. Now, it is permanently stuck on that screen. Even if I try to hold the volume down to get to the boot loader when it starts, it still goes to this screen.
What can I do to try to get out of this? I cant go back to my recovery to get my backup.
Thanks

The first time I tried to Root my phone, I had the same problem with Toasts Root method. That's stock Recovery you're seeing.
I ended up having to use Unrevoked Linux version and swore I would never unroot again, and I haven't.

I've tried using unrevoked and several other methods. The problem is I think most of them rely on the phone being on with USB debugging enabled. I unfortunately can't get there. The one ray of hope I have is that the device is recognized in my device manager as "Android USB device - HTC bootloader". Is there any other way I could fix this?

Are you holding power and volume down at the same time. Sounds like you are just holding volume. When you get to the bootloader I'd you see s-off all you will need to do is flash a PC36IMG of the recovery of your choice(I recommend twrp). Good luck!

Also, no need to unroot for any rom. Once you are rooted you can flash anything you want. Compatibility wise, you may need to update a radio but that is just flashed in recovery.

Thanks for the reply. Unfortunately I am holding power and volume down. Powering it on normally and powering it on while holding volume down both go to the same screen.

[Q] Stuck in bootloader HTC one x

I made a series of follies trying to root my phone. Using Hasoon 2000's all in one HTC one X kit I tried to install CWM recovery before I rooted the phone. When I tried to go into recovery mode after that it would just give me that red script with the legal warning underneath the HTC boot screen and stay there. In my attempt to fix the problem I tried to flash the stock kernal which resulted in me getting stuck in a boot loop to the HTC screen with the red warning. Factory reset did not do anything. So I had the brilliant idea of re-locking the boot loader.
So now my phone boots up to the bootloader screen, no matter what I do. Factory reset, boot into recovery mode, reboot, all lead me back to the same place.
Fastboot does seem to be working which leaves some hope I can un-brick this thing. I tried several times throughout the process to clear the fastboot cache through the ADB shell which seems to have executed successfully, but made to no difference.
Can someone walk me through the steps to get back to a working phone with a working recovery mode? Help would be much appreciated!

Search XDA for "red triangle", there are quite a few posts about how to fix that.

Please use search.
There is a tread in which it is describe how to fix your phone " from disaster "
I think it is in One X Android ROM section.
Search for tutorial and disaster pr something like this.
Hope this will help you.
Regards.

{UPDATE} : I was able to unlock my bootloader again which now results in a bootloop to that HTC screen with the red legal notice. I can get into the bootloader if I power on with volume down.

[Q] Stuck at splash screen, cant enter recovery.

I have an htc one as stated above. It is rooted and has s-off but at the time things went wrong I was running my stock rom.
Yesterday when I went to pause my music my screen froze. I tried turning my phone off and when I attemtep to reboot it all I got was the htc white logo screen. It will remain on this screen until I turn the phone off.
I can enter the bootloader but the options don't work (reboot only turns the phone off, factory rest freezes the bootloader) I have tried everything to fix this, from locking the bootloader and using an RUU exe (locking the bootloader failed) to reflashing the recovery (gave me the error "remote image update error).
The thing that I really don't understand is why this happened, I wasn't even doing anything and my phone just crapped out on me.
I need this phone back and I don't know what to do, any help is greatly appreciated.
Thanks!

Oh, and the best part is that all of this happened AFTER I already filed a warranty claim for the phones faulty mic. My new device comes tomorrow and if I send them this one back I'll be out 600 bucks.
Is there any way to fix this?

Additionally, everything is still unlocked (bootloader says unlocked, still have s-off) and there is no tamper evidence either.

When you enter your boot loader, what does the following command give you: fastboot devices
If you get your phone in response, you are not out of hope.

Help please: recovery.img specifically for HTC Desire 820 Lollipop required.

Hi All,
Long time reader, first time poster
Short story: I just need a straight link to a recovery.img file specific to my device which is a HTC Desire 820.
Long story:
- Upgraded my phone to Lollipop.
- Unlocked my HTC phone.
- Followed a guide on the net regarding flashing TWRP recovery image and rooting (did not realise I was unknowingly flashing a previous / incompatible version on my phone).
- Now stuck with a phone that can't boot to recovery or factory reset (because it then tries to boot to recovery when doing this).
- I can get into the boot loader screen and fastboot, but selecting HBOOT and then RECOVERY makes my phone vibrate a little and flashes a message, but then goes back to the boot loader screen.
- I tried to flash another recovery.img file, but this just made it so that the HTC logo is displayed and doesn't get passed that.
- Now I just want to flash the lollipop recovery.img so that I at least can root the phone and not necessarily install TWRP.
Any ideas?
Thank you in advance.

So... no ideas?
lol *bump*

Post your device model, i.e. 820n...820u...

Thanks for responding and providing guidance @tomal.
The model of my phone is: HTC DESIRE 820 Model Number: OPFJ50.
Thank you in advance.

Power of your device and connect the device to the charger when it is in power off after connected you quickly press vol up+power button or vol down+power button then you find a charging logo then release the buttons after tha the phone goes off automatically then you quickly press vol down button only it gets the bootloader then you flash the only lolliop stock official recovery.img because twrp of 64 bit having some bugs.but they fix it you wait for some time.

keep on pressing the power button for a minute and then restart into the os .
still searching for the recovery.img compatible with htc desire 820.
please if you get let me know at [email protected] .

Flash stock official recovery....it having no bugs while booting,restarting,formatting the phone. but it can't handle the ota updates. You have also wait for some more time they will updated best recovery or stock ruu or how to s off.

Hi, I don’t know who or were to ask, my HTC Desire 820 was working fine, no problem at all. I got a voice chat and while listening there was a loud noise and the device shut off. After a few seconds it booted back up and didn’t load android, it was on a constant bootloop. I couldn’t turn it off or anything. After a while it shut itself down. Assuming the battery was low I connected it but to my surprise it wasn’t charging, the orange LED was blinking. I leave it plugged in for more than one hour but the situation continued, the phone was not powering on and the led was flashing. At that point what I did was to remove the back cover and reset the battery which make it begin to charge normal. After 30 min I tried turning it back on but the boot loop was still there. I could manage to enter fastboot and perform a factory reset. After it finished the device was booting back up and at a certain point the bootloop start over. The device was not rooted, bootloader locked, everything stock, since I didn’t want to mess with it because it is my only phone at this moment. I think on unlocking bootloader, and rooting to try install a custom rom or a backup save from someone. I have been able to unlock bootloader but TWRP doesn’t load, the device will not go into custom recovery and I have tried several versions. Now I don’t have the stock recovery anymore. I can go into bootloader, but nothing else.
I have to mention that now I have more than 24H dealing with this with no luck or signs of fixing my phone. Please, please any one that can help I will be very grateful.
My phone info is the following
HTC Desire 820 dual sim.
A51_DTUL PVT SHIP S-ON
HBOOT-3.19.0.0000
OS-2.10.709.2
SEP 25 2015

SO in this way you have to s off the htc desire 820 and flash the ruu means os zip file in bootloader or type the command fastboot rebootruu in fastboot mode then flash the ruu with fastboot files with the help of computer.

But as far as I have read there is no way to S-OFF the Desire 820 so far. And I havent been able to find any RUU on the web

It is there to s off but you have to pay some money with the help of sunshine

I have used it before with another device I had. and to be honest I will be glad to use it again. the big problem here is that the phone is not booting, so I cannot install sunshine to gain S-OFF.
If there is any other way to get it done or something to allow me boot to the OS it will be great

The only solution for this is wait for a few days.because the htc desire 820 is the first model to get android 64bit.so the developers are not able to develop thirdparty code for it.if the device is locked go to the service center and give the phone they are all having the more stock roms to flash it.

Device Bricked

Hi,
I had unlocked my boot loader to flash TRWP. But after unsuccessful attempt of H2OS installation I tried relocking my boot loader. Now device is not starting and its just showing blank screen. White Notification LED is there but nothing on screen. Need urgent help.

You...locked it with H2OS and...what recovery? What did you even do

I had official TWRP installed. I booted device into Fastboot mode and run "oem bootloader lock" command

Why? there is no real disadvantage to having unlocked bootloader and relocking often results in problems,. I have read of people recovering from this after contacting opo CS so that would be my advice

Hi, this is my first post but I had a similar problem after flashing H2OS and relocking bootloader. I solved it by holding down the power button until the white LED went out and then I booted into fastboot (power + Vol up) . from there I unlocked the bootloader and since then the phone seems to be working fine.
I hope that helps, at least in the short term
I am using OnePlus 3 with TWRP recovery and H2OS.
